Scientists suggest spacetime has no time dimension

(PhysOrg.com) -- The concept of time as a way to measure the duration of events is not only deeply intuitive, it also plays an important role in our mathematical descriptions of physical systems. For instance, we define an object’s speed as its displacement per a given time. But some researchers theorize that this Newtonian idea of time as an absolute quantity that flows on its own, along with the idea that time is the fourth dimension of spacetime, are incorrect. They propose to replace these concepts of time with a view that corresponds more accurately to the physical world: time as a measure of the numerical order of change.

In two recent papers (one published and one to be published) in Physics Essays, Amrit Sorli, Davide Fiscaletti, and Dusan Klinar from the Scientific Research Centre Bistra in Ptuj, Slovenia, have described in more detail what this means.

No time dimension

They begin by explaining how we usually assume that is an absolute physical quantity that plays the role of the independent variable (time, t, is often the x-axis on graphs that show the evolution of a physical system). But, as they note, we never really measure t. What we do measure is an object’s frequency, speed, etc. In other words, what experimentally exists are the motion of an object and the tick of a clock, and we compare the object’s motion to the tick of a clock to measure the object’s frequency, speed, etc. By itself, t has only a mathematical value, and no primary physical existence.

This view doesn’t mean that time does not exist, but that time has more to do with space than with the idea of an absolute time. So while 4D spacetime is usually considered to consist of three dimensions of space and one dimension of time, the researchers’ view suggests that it’s more correct to imagine spacetime as four dimensions of space. In other words, as they say, the universe is “timeless.”

“Minkowski space is not 3D + T, it is 4D,” the scientists write in their most recent paper. “The point of view which considers time to be a physical entity in which material changes occur is here replaced with a more convenient view of time being merely the numerical order of material change. This view corresponds better to the physical world and has more explanatory power in describing immediate physical phenomena: gravity, electrostatic interaction, information transfer by EPR experiment are physical phenomena carried directly by the space in which physical phenomena occur.”

As the scientists added, the roots of this idea come from Einstein himself.

“Einstein said, ‘Time has no independent existence apart from the order of events by which we measure it,’” Sorli told PhysOrg.com. “Time is exactly the order of events: this is my conclusion.”

In the future, the scientists plan to investigate the possibility that quantum space has three dimensions of space, as Sorli explained.

“The idea of time being the fourth dimension of space did not bring much progress in physics and is in contradiction with the formalism of special relativity,” he said. “We are now developing a formalism of 3D quantum space based on Planck work. It seems that the universe is 3D from the macro to the micro level to the Planck volume, which per formalism is 3D. In this 3D space there is no ‘length contraction,’ there is no ‘time dilation.’ What really exists is that the velocity of material change is ‘relative’ in the Einstein sense.”

Numerical order in space

The researchers give an example of this concept of time by imagining a photon that is moving between two points in space. The distance between these two points is composed of Planck distances, each of which is the smallest distance that the photon can move. (The fundamental unit of this motion is Planck time.) When the photon moves a Planck distance, it is moving exclusively in space and not in absolute time, the researchers explain. The photon can be thought of as moving from point 1 to point 2, and its position at point 1 is “before” its position at point 2 in the sense that the number 1 comes before the number 2 in the numerical order. Numerical order is not equivalent to temporal order, i.e., the number 1 does not exist before the number 2 in time, only numerically.

As the researchers explain, without using time as the fourth dimension of spacetime, the physical world can be described more accurately. As physicist Enrico Prati noted in a recent study, Hamiltonian dynamics (equations in classical mechanics) is robustly well-defined without the concept of absolute time. Other scientists have pointed out that the mathematical model of spacetime does not correspond to physical reality, and propose that a timeless “state space” provides a more accurate framework.

The scientists also investigated the falsifiability of the two notions of time. The concept of time as the fourth dimension of space - as a fundamental physical entity in which an experiment occurs - can be falsified by an experiment in which time does not exist, according to the scientists. An example of an experiment in which time is not present as a fundamental entity is the Coulomb experiment; mathematically, this experiment takes place only in space. On the other hand, in the concept of time as a numerical order of change taking place in space, space is the fundamental physical entity in which a given experiment occurs. Although this concept could be falsified by an experiment in which time (measured by clocks) is not the numerical order of material change, such an experiment is not yet known.

“Newton theory on absolute time is not falsifiable, you cannot prove it or disprove it, you have to believe in it,” Sorli said. “The theory of time as the fourth dimension of space is falsifiable and in our last article we prove there are strong indications that it might be wrong. On the basis of experimental data, time is what we measure with clocks: with clocks we measure the numerical order of material change, i.e., motion in space.”

How it makes sense

In addition to providing a more accurate description of the nature of physical reality, the concept of time as a numerical order of change can also resolve Zeno’s paradox of Achilles and the Tortoise. In this paradox, the faster Achilles gives the Tortoise a head start in the race. But although Achilles can run 10 times faster than the Tortoise, he can never surpass the Tortoise because, for every distance unit that Achilles runs, the Tortoise also runs 1/10 that distance. So whenever Achilles reaches a point where the Tortoise has been, the Tortoise has also moved slightly ahead. Although the conclusion that Achilles can never surpass the Tortoise is obviously false, there are many different proposed explanations for why the argument is flawed.

Here, the researchers explain that the paradox can be resolved by redefining velocity, so that the velocity of both runners is derived from the numerical order of their motion, rather than their displacement and direction in time. From this perspective, Achilles and the Tortoise move through space only, and Achilles can surpass Tortoise in space, though not in absolute time.

The researchers also briefly examine how this new view of time fits with how we intuitively perceive time. Many neurological studies have confirmed that we do have a sense of past, present, and future. This evidence has led to the proposal that the brain represents time with an internal “clock” that emits neural ticks (the “pacemaker-accumulator” model). However, some recent studies have challenged this traditional view, and suggest that the brain represents time in a spatially distributed way, by detecting the activation of different neural populations. Although we perceive events as occurring in the past, present, or future, these concepts may just be part of a psychological frame in which we experience material changes in space.

Finally, the researchers explain that this view of time does not look encouraging for time travelers.

“In our view, time travel into the past and future are not possible,” Sorli said. “One can travel in space only, and time is a numerical order of his motion.”

while it is simple enough for even an arm-chair philosopher to ponder, from the late Gene Rodenberry of Star Trek fame I did learn alot about the heavens, logic, science in general.

I've known for some years that Time and Distance have no substance. Time and Distance are the same thing from different perspectives, measuring the same thing with different scales.

Finally, that you say that there can be no such thing as Time travel is a phenomenal admission of truth, I applaud it and you. To be able to time travel would require the establishing and choosing of an object with a known and absolute position. This is clearly an impossibility.

1. there are no stationary objects in Space. everything moves;
2. there are no objects traveling a straight vector;

In dense aether model of space-time with water surface the space dimension corresponds the direction parallel with water surface, the time dimension corresponds the direction perpendicular to water surface. It explains, why we can move in space easily, but not in time. And it illustrates too, why time always has an arrow (density gradient) assigned, whereas the space not. The removal of time from physics may solve some isolated problems, but it will bring a much more problems in another areas, so it's not advantageous from utilitarian reasons.

In AWT the structure of space-time gradient is composed of pair time antiparallel time dimensions. The objects traveling in time into past will collapse, those traveling into future will expand instead bellow 2 cm dimensional scale, above it the time arrow is reversed.

http://www.aether...part.gif

It means, for every phenomena existing in dimensional scale above the scale of observer (wavelength of CMBR ~ 2 cm) exists anti-parallel phenomena, for which the entropic time arrow is reversed. Above 2 cm scale the pressure of radiation is balanced with gravity and the seeming expansion of space-time in visible light is balanced with collapse of space-time in radio waves.

You can predict quite wide range of new phenomena with this model, for example we can expect, the radiowaves will exert a negative pressure of radiation.

In AWT the picture of Universe will change pronouncedly, when you would observe it at different wavelength.

In visible light the light of more distant sources will attenuate faster, than it corresponds ISL and it becomes reddish. In microwaves these phenomena disappear and the Universe would appear as flat, transparent and huge, as possible - no gravitational lens and CMBR shielding and Sunyaev-Zheldovitch effect disappears.

http://www.tgdail...t-at-all

In radiowaves the gravity lens will switch their refractive index and the free space between galaxies will focus the EM radiation, instead. The background radio emission, which is the component smoothly distributed across the whole sky, will appear more brighter, than corresponds the distance of source. And the remote galaxies will appear larger, not smaller (as the classical model of space-expansion implies).

I've posted this before and I'll post it again, seeing as this article says what I've been saying sortof --> time is the result between two distinct bodies of energy interacting, and on it's smallest scale in a universe that has 0 movement and is absolute 0, there is no time, no need for it. In this universe we are constantly flowing through the zero point field and it is this constant motion which is ultimately the driving factor for a dimensionless time that doesn't run fluid universally but can occur at varying speeds --> when you move faster time slows to accommodate all of that extra interaction between your bodies of energy and other bodies of energy. Even if you have empty space and a stationary photon, the space is moving all around it and thus time is necessary.

Regarding the entropic time definition we should realize, it's energy density and distance scale dependent. Above 2 cm scale all density fluctuations of vacuum tend to agglomerate into larger pieces spontaneously because of gravity - this is the domain of relativity theory. Bellow this size the CMBR fluctuations tend to disperse all objects into smaller ones, instead. This is the domain of quantum mechanics theory, which doesn't recognize the gravity and in which the wave packets of all particles expand into infinity. The definition of time arrow by spontaneous entropy arrow will therefore depend on the dimensional scale used and the entropy of the Universe as a whole will not change - it's observer dependent. A primitive observers will perceive the Universe smaller and primitive too, whereas the more complex observers will perceive it larger and more complex. The intelligent life occupies the 2 cm dimensional scale just because this scale provides the highest stability in CMBR field.

..if you have empty space and a stationary photon, the space is moving behind it and thus time is necessary.
IMO Sorli's definition of time is silly and tautological. You cannot define the time as a numerical order of material change in space, because this order is defined with light (or another energy spreading) in time. In AWT the existence of time cannot be separated from existence of space. We can imagine it like density fluctuations inside of dense gas. If this gas would be completely homogeneous, then we could see anything from it. But at the moment, when we can observe something, because some density gradients exist in it, then the reality will become oriented: the transverse waves of light will spread along the longer side of gradients (and they will define the space dimension in such way), whereas the longitudinal waves will prefer the shorter one. The existence of gradient implies the violation of symmetry of reality and its breaking into time and space dimensions.

This boundary is not sharp, but the probability of spontaneous evolution of quantum computers (not saying about more complex forms of intelligence) is highly improbable at the terrestrial conditions. The existence of stable quantum computers is dependent on the human care, which will provide the shielding and cooling. The compatibility with wavelength of CMBR is the reason, why the highest number of living species reaches just the size up to 2 cm (insect, plankton) and why human brains operate just with neurons of the same size. The coastal shape, the surface of clouds, the shape of trees and leaves etc. are most richer for this dimensional scale, too.

The article seems to keep talking about "motion" and "change" without time. The example of the photon moving one Planck length in four dimensional space. So does this bring in the necessity of particles as history lines and require strong determinism?

Just when I was getting used to having free will again.

If a photon moved a Planck length in 4D between point 1 and 2 and struck something in just the right way, could it reflect back to point ? Why not?

Frankly I don't understand this stance at all. What Mr. Amrit Sorli basically does, he's trying to replace the time formulation with his own spatial one - and after then he is saying, the formulation of time as another dimension of space is wrong. Every theory has its weak and stronger parts. For example the concept of extradimensions is the best part of string theory and the four dimensional definition of space-time is the strongest part of relativity theory. It's not surprising, Einstein was so upset, when Minkowski published it in 1910 - it actually put the relativity into another level.

So if the Planck length is the minimum distance that a photon can move, and the speed of light is constant, and light cannot escape the gravity well of a black hole, then it must be that gravity is creating units of space in the path of the photon at a rate faster than (or at least as fast as) the photon can hop to the next unit. The speed of light would still be the speed limit for motion, but space would be created (or destroyed) spontaneously, like some sor to quantum foam. Would that be what quantum gravity is about?

Gravity could also be thought of as dragging space into the black hole, but that would imply motion, which leads back to the speed of light being exceeded. Dragging is not necessary to get things to fall into the black hole. If gravity creates more units of space on the far side of an object in a gravity well, and destroys them on the near side, then space would act like a conveyor belt toward the center, without necessarily having any true motion of the object.

I'm saying, the wavelength of CMBR enabled to evolve human brain neurons of the same size, which makes the Universe symmetric around human observer size. The distance scale of most chaotic portion of Universe (the CMBR photons) therefore corresponds the distance scale of most complex portion of it (it's the human brain). I'm opened to admit the exception for your brain, though - if you insist on it.

I guess "creating" units of space is not right. If units of space are constantly popping into and out of existence on their own, then gravity could be defined as the tendency of units of space to persist. The stronger the gravity (i.e., the closer to a massive object), the less likely the unit of space will persist, so other objects will tend to remain close. The farther from a massive object, the more likely that units of space will persist.

Maybe that could account for dark energy; all you need is a lot of space between objects, which is what you have in intergalactic space, and even moreso between galaxy clusters.

what looks like things popping in and out of existence is just our most microscopic view of things and if we could see even further to smaller things we'd see that there are smaller forms of energy that make this all happen. Seriously things do not pop in and out of existence, that is an illusion caused by having a limited view of what is really happening. That is what your zero point field is all about. Who knows perhaps neutrino radiation has a huge role to play in the universes accelerated expansion, produced by the nature of fusion and fission reactions. Neutrinos are not inert there is something very important about the fact that they are so ghostly and can transition through matter with only very weak interaction. I would think that most of what there is to discover in particle physics are more and more such ghostly things but I can tell you that aether, is not one of them and never will be.

AWT is general theory and it doesn't predict well the particular phenomena (which are maintained well with particular theories). But the concepts of time and space are explained in it quite well. As an analogy of timeless and space-less universe can serve the underwater for surface ripples. Although such underwater is full of fishes, for surface waves it simply doesn't exist, because they cannot spread through it. It's too chaotic and disarranged for them. You can model the space-time formation in such environment with condensation of supercritical water vapor, for example. At the certain moment the stringy density fluctuations will emerge, which will enable the propagation of transverse waves at distance. On the picture bellow is an example of such space-time foam formed with condensing supercritical carbon dioxide fluid.

2) the gravitational lenses disperse the radiowaves
3) for microwaves the gravitational lens don't exist
4) the intensity of radiowave sources would violate the ISL in positive way
5) for microwaves the Sunyaev-Zheldowitch effect doesn't exist
6) the remote galaxies shrink with time, not expand
7) for radiowaves the pressure of radiation is negative

Which other theory predicts this? You should consider, Einstein predicted just the gravitational lensing and he become famous immediately.

What is being suggested about time must also then hold true for 3D space.

Dimensionality is applied incrementalism, regardless of which dimension we speak of. All dimensions are measures of relative motions. This a purely a function of mind in relation to reality. Reality without an observer can only be discussed theoretically, same as Reality with one.

Non-dimensional Reality with infinite dimensions experienced by mind.

All phenomena are "real" experiences of mind using conceptual dimensionality to order experience. A self-sustaining causality loop we cannot escape for the rather obvious reason that we could not experience otherwise.

For those who don't understand the necessity of the observer, I ask how there can be relative measures without? With a purely hypothetical referent, imaginary baselines and such, it still requires someone to hypothesize. With so called "real" or "physical" referents, these have to be selected as the basis for all subsequent applied dimensionality.

The time and space concepts are highly symetric. The wide class of animals (dolphins, bats, insects) are using longitudinal waves of sound instead of transverse waves of light and they're navigating through space-time with time intervals instead of space intervals. And their brains are quite comfortable with it. Even some blind people can navigate through space-time via time intervals. The space-time symmetric world is therefore not so distant from our reality, as many people believe.

The helium atoms in vacuum are doing eternal motion in the same way, like the pollen grain in water by Brownian motion (as the result, the cooled helium never freeze at room pressure - it's macroscopic effect independent to observer). Many other phenomena (Casimir force, for example) have their exact counterparts in material environments. So I don't think, such phenomena can be explained just with our limited view. The conclusion is, the vacuum around us is physically moving and we are swimming in it like fishes in water or better to say, like the quantum vortices inside of superfluid - just its incredible density disallows us to observe it directly.

3) for microwaves the gravitational lens don't exist
"The basic reason for the small amplitude of this effect is that gravitational lensing preserves surface brightness density. In the case of discrete sources, this sort of effect can result in magnification, but it's not something that will induce anisotropies in a uniform background."

Finally, that you say that there can be no such thing as Time travel is a phenomenal admission of truth, I applaud it and you. To be able to time travel would require the establishing and choosing of an object with a known and absolute position. This is clearly an impossibility.

1. there are no stationary objects in Space. everything moves;
2. there are no objects traveling a straight vector;

thanks very much.

.."if radio waves are shifted into the ultraviolet part of the spectrum, we still say that the light is redshifted - shifted toward lower frequencies"..
So shift to ultraviolet part of spectrum is the shift toward lower frequencies? Wow...

OK, where's the boundary of the "red-shift" concept, after then? Where is the wavelength of the "red"? If infrared waves are shifted into the ultraviolet part of the spectrum, can we still say, that the light is redshifted?

Mathematic is based on formal logics. If you have theory defined logically, their logical deductions cannot violate it or any math, which is built on this logical framework later. For example, the order of Venus phases in heliocentric model is difficult to formulate mathematically, nevertheless it still provides the clear prediction and the way, how to falsify the geocentric model.

For example, string theory is using Lorentz symmetry postulate (of relativity) and the existence of extradimensions. Which it the logically flawed combination, because the extradimensions would manifest itself just with Lorentz symmetry violation. So we can say safely, string theory is fringe theory and it cannot lead into distinct solution, because it's based on the logically inconsistent postulate set. And you needn't to derive any equation for being able to recognize it.

Unfortunately the time is not what we are perceive as the expansion of the Universe. But we can define the time with entropy and if entropy of Universe is wavelength/distance scale dependent (as AWT implies), then the entropic time arrow at general scale doesn't exist in the same way, like the space. Which corresponds the notion of infinitely dense aether, which is so stochastic, no wave can spread through it in the same way, like the surface waves cannot spread in underwater. Such aether is experimentally undetectable, after then - although it could be still full of fishes and dolphins or whatever else... Such insight still doesn't differ from dispersive perspective at the water surface: at the sufficient distance every causal ripple disappear in the underwater noise.

If we would prove, the Universe is collapsing instead in the long-wavelength spectrum, will it prove, we don't exist? In AWT the expansion of Universe is dispersive effect of vacuum fluctuations. If these fluctuations would disappear, we wouldn't observe anything, not just time. Apparently the existence of CMBR noise is more fundamental, then the existence of entropic time in the same way, like the existence of water is more fundamental, than the existence of water surface (in supercritical water no surface exists).

The dispersion of ripples at the water surface cannot be described with formal math in deterministic way - nevertheless it still has some logics in it. The physicists are ignoring the emergent multiparticle phenomena systematically just because of the absence of reliable models - but it doesn't mean, these phenomena doesn't exist. We exhausted nearly all meaningful ways, how to describe universe in deterministic way, so I'm trying to draw inspiration from these indeterministic ones.

A blueshift is any decrease in wavelength (increase in frequency); the opposite effect is referred to as redshift.

I'm quite sure about red-shift regarding the distributed radiowave background. But I'm not so sure regarding the negative refraction of radiowaves with gravitational lens. We should realize, the radiowaves are spreading in inverse space-time, so that their refraction with black holes is negative from perspective of these black holes - but from our perspective it still appears positive. After all, the same effect could explain the positive rest mass of antimatter at the high energy spectrum. At the water surface the celerity curve doesn't go through inversion, just through the infimum. The math will not save you from sign inversion, if you haven't robust logical model on the mind.

The dispersive model of Universe expansion is quite apparent for distant galaxies in Hubble deep field, which appear much larger, than the galaxies in our proximity.

http://arxiv.org/abs/1011.4956

In this case the mainstream physics recognized quite correctly, they appear larger, because their light is blurred with the CMBR noise in the same way, like the distant lights observed through fog. The question only is, why the red shift isn't explained with dispersion in the same way?

But recently we are observed many well developed galaxies in the Hubble deep field, which excludes the possibility, such galaxies could evolve during Big Bang. If we have galaxies older than the visible part of Universe and the red shift, then the tired light model is the only feasible explanation.

The atemporal universe concept of A. Sorli or Whitehead is not new in physics at all. These atemporal ideas we can find in work of J.A. Wheeler, D. Bohm, J. Barbour, P.Yourgrau, Dennis A. Wright, P. Lynds, Ron Larther and many others. But I'm still missing the testable predictions with atemporal approach. The explanation of Zenos paradox is not enough, because we have other interpretations, which are explaining it as well and they even lead into testable predictions (compare the quantum Zeno's effect)

http://en.wikiped...o_effect

We can say, whole the quantum mechanics is basically atemporal, because the immediate values of wave function aren't observable directly from outside of quantum objects. Therefore in quantum world the atemporal model of universe is of much larger relevance, than in relativity world.

As I've said before and received low marks for:
Time travel is impossible. Physics understanding of time leaves much to be desired and is probably wrong. Now is simultaneous everywhere, and there is only now. The passage of time is purely perceptual and relative, measured by benchmarks. Ours are the speed of chemical reactions and any changes we perceive in the passage of time anywhere is just a change in the speed of our benchmarks, not a change in time.

This article shows that physics is starting to learn a bit about time.


I've also said: there aren't lots of dimensions as string theory requires, time is not the 4th dimension, you can time travel to the future but only by existing in every intermediate instant, wormholes may exist but will only allow spatial travel not time travel and the universe is a sphere

Congratulations on the article, Amrit. I'll have to add my two cents though:
Humanity treats time as a linear progression from past to future because it is foundational to the narrative function that is the basis of serial cause and effect rationality. The problem is physically modeling it as such. It is not that the present moves from past to future, but that the changing configuration of what exists, turns the future into the past. We don't travel the fourth dimension from yesterday to tomorrow. Tomorrow becomes yesterday because the earth rotates. The present is the constant and it is the events which come and go. Physically, past and future do not exist, because the same energy is just changing configurations. As an effect of motion, time, rate of change, is similar to temperature, level of activity.
Quantum mechanics uses an external, absolute clock because it admits simultaneity and so the process goes from past simultaneous configurations to future ones.
brodix
1 / 5 (3) Apr 25, 2011
Relativity models time as part of the four dimensional geometry, in which points in space and time exist relative to one another and there is no absolute time.
If we were to eliminate the external clock from QM and just consider time as the dynamic, it is the collapsing of future probabilities which leads to current actualities. While all input into any event exists prior to its occurrence, the lightcone of this input only comes together at the point of occurrence. So while all physical laws deciding the outcome are deterministic, the total input cannot be known prior to the occurrence, so it is still probabilistic. Even if there were a method of faster than light communication to gather knowledge of all input prior to an occurrence, then the same faster than light potential could exist for information affecting that outcome and so the problem would be repeated.

I agree Lorentzian contraction isn't "real" because even approaching C the object doesn't locally perceive any change in time or physical contraction. From our low velocity inertial frame we perceive contraction and spatial deceleration because like 2D stick figures that can not perceive 3d displacement, we can not perceive 4d displacement. beyond .707C the object appears to slow down while contracting faster. locally both frames still measure C, normal energy density and no time dilation because these can only be revealed by relative measure. The biggest consequence may not be at the astronomical scale and increased energy density for acceleration or equivalently gravity wells but at the ano scale where Casimir supression causes lower energy density. Here we can find an explanation for condensed gas like deuterium ice or fractional hydrogen because now we are loading gas into larger "volumes" of space than should exist given exterior dimensions - paralell parking gas on the time axis

An intuitive understanding of reality necessarily implies that is has been conformed within this conceptual structure. This may be an issue wrt intuitive understanding, because unconceprualized reality (noumenal reality),... may not contain these a-prior subjective artifacts of the mind, yet observations still must be made consistent for science to make predictions.

To me, what we are used to calling "time" is a ratio comparing two instances of change. In an example, one of them is the rotation of a second or minute hand on an analog clock, and the other is the movement of a runner along a track. We say the runner covered a quarter mile in a minute, but really we are comparing the distance of 1/4 mile with the distance between minute markings on the clockface. Where is the time? It's not being measured - just two measurements of spatial dimensions only.

Is time the basis of motion, or motion the basis of time?
If you want to derive time from motion, all you really need is change of configuration, but how do you derive motion from time?
Time is deduced from measurements of motion. What exactly is time? Entropy? Change? Duration? Fourth dimension?
We perceive the present as moving from past events to future ones, but we also perceive the sun as traveling across the sky. It took awhile to understand how this process worked. It should be noted that epicycles were extremely mathematically precise. The problem was conceiving a physical explanation for why they were so effective.

In order for these researchers to be correct they need to address time in general relativity, specifically the implication that CTL's can exist in a consistent solution to the EFE.

And all I am saying is that Superman went back in time man!!!... Relativity wreaked havoc on time....

The math describing relativity is accurate. The problem is when we attach a physical description to it and come up with warping spacetime, wormholes, blocktime, etc.
The math behind epicycles was also quite accurate. It was just when they tried to develop a physical theory to explain it and came up with giant cosmic gearwheels.
Ask yourself, when you pour a cup of coffee and eventually drink it; did you travel some meta-physical dimension from pouring it to finishing it, or did the event of your pouring it recede into the past, as you eventually consumed it?
Is there some physically real dimension of time, along which the present moves, or is it a changing configuration of what exists, such that each event recedes into the past, as the configuration of what exists changes? If you allow change in the present, then measures of duration are relative to physical context.

What are you talking about? We have, so far, demonstrated General Relativity to be an accurate theory to predict and explain observations we make in the physical world. If you don't "attach" it to the physical world it is just a set of equations.

Now, if you are referring to the problem with finding the physical "cause" of relativity, that is where if these guys are right we would need to adjust GR since it allows for CTLs and the like.

The rest of what you say is just babble.

I'm with rwinners. Replacing "time" with "change" is purely cosmetic. So if the previous state of the Universe was X0, and the new one is X1 obtained by the change function F with X1=F(X1)... Applying this recursively, don't you implicitly obtain a state-space model with X[t]=F(X[t-1])?

You're just replacing God's loop with infinite recursion. I sure hope the Universe's call stack is huge! Unless it features some form of tail-recursion optimization, which is... you guessed it, a loop.

I was kidding but the main point is that a total ordering of events/change is equivalent to an independent variable of time.

I understand thought that the concept may be more useful in cases where you can follow a chain of events forward and end up where you started -- closed time-like curves and the like -- but I thought existing theories of manifolds were already able to cope with that (being no expert on Riemannian geometry and its cousins).

@Pyle:

Unfortunately Zephir can't be so easily dismissed. Good try though.
Yeah, I know. I've seen others try and likewise fail. That's why I think he's a chatbot. I suspect that not even a completely insane person could learn as little as he has in the years he's been posting here. I was just venting some long held frustration. I really liked knocking down his "predictions" (it wasn't very hard to do).

(On the fermion point, I believe he is calling the particle-antiparticle pairs fermions not the CMBR photons.
I suspect as much too, but the CMBR (that we detect) is entirely made of thermal radiation (photons). If he wants to prove their source is ZPE, he's going to have to prove it locally.

But he talks in circles so who knows.)
Aint that the truth!

I am anxious to see his replies.

@yyz:

Some good posts here;
Thank you.

The "Atlas of the Universe" site was (AFAIK) created and maintained (at least up to 2006) by Richard Powell, a British astrophysicist:
Right. That was my reference, not Zephir's. But I can see how you might get confused by the way I put the text together. The quote above the atlas link was from the atlas. My sentence below it referred to an earlier post of Zephir's.

Pretty cool site, too.
I love the atlas as it's well done, and layman accessible.

Zephir's stupid reference (written by the schoolteacher and geologist) was this one:

http://arxiv.org/abs/1011.4956

Even though these observations have been explained to him, in some detail, here is yet another claim of objects in the universe OLDER than the universe.
Right. That's why I'm hoping my responses to his "predictions" will slow him down a little. They're reference-able and absolute proof his "theory" is useless and meaningless.

what looks like things popping in and out of existence is just our most microscopic view of things and if we could see even further to smaller things we'd see that there are smaller forms of energy that make this all happen. Seriously things do not pop in and out of existence, that is an illusion caused by having a limited view of what is really happening. That is what your zero point field is all about.

Apologies for my "Atlas of the Universe" mixup & thanks for setting me straight.

But yeah, I've seen him ref the Unzicker-Fabian paper multiple times (myself and others here have pointed out some of its flaws to on several occasions). What's interesting is his occasional practice of referring to some exotic, dense theoretical paper in PRL or ApJ and such and claim that it backs up some wild claim of his (this while he has already admitted that this knowledge of mathematics, especially at these levels, is lacking). Better yet, sometimes they refute his claims!

Great to hear VestaZ is history. Usually when Zeyphir's posts are getting pounded rather thoroughly, a few new sockpuppets appear to parrot his claims.

After listening to all the arguments and counter arguments in these comments... The following may be closer to actual reality...

If total (overall) 3-dimensional cosmic space exists as a hyperspherical geometric (spiral vortex, triple loop, double helix) standing wave which must have an endless inner series of fractal involved harmonics... Then, metric time exists solely as a measure of its change from one frequency phase order (spectrum) to another, ad infinitum down to the smallest virtual sub quantum particle-wave in the Planck volume.

When such total space collapses back to its initial ZPE singularity (i.e., its unconditioned, potential energy state prior to its initial dimensional manifestation or cosmogenesis) Its associated metric time would also cease to exist as it resolves back to its initial state of zero-change or infinite duration (i.e., potential metric cosmic Time) along with its total potential mass/energy (ZPE or angular spin momentum)...

I have an idea for a time machine. It comes from my lack of understanding on what antimatter time reversal could mean. Here it goes:

Instantly convert a human into antimatter inside a vacuum chamber. I have no earthly clue as to /how/ that could possibly be done, but let's just say it's possible in principle (feel free to critique the feasibility, though). The object now travels back in time. Since parity is reversed, could it also move "backwards" in space, thus following the past trajectory of Earth through space?

Inside the vacuum chamber, put a portable, opposite, version of the device in the chamber so the time traveler can reverse the process and "stop" traveling backwards and "enter" its new "present time".

Even if this were all possible in theory, I can't imagine how the object could move backwards in time any faster than time normally proceeds. So, the further back you want to go, the longer you have to wait, I guess. Also, once travels stops; annihilations???

Accordingly, Sorlis claim (referring to our 3-D physical space) that Time is exactly the order of events; and with clocks we measure the numerical order of material change, i.e., motion in space is entirely correct.

Its, therefore, entirely foolish to think that Time can be a dimension of physical space itself, that the arrow of time can be reversed, or that travel in time by physical beings is possible.

Obviously, while fractal involved 3-d space cannot exist without metric time (i.e., change in motion, frequency, position, force, etc.) with the first change being the initial emanation, at near infinite frequency, of the 1-d force ray (from the ZPE spin momentum singularity) that compose the initial cosmic fields... Such changes in time cannot be considered an actual linear dimension of the 3-d space itself... e.g., How can the changes in frequency of light (that determines color, etc.) be a property of the space that contains the photon waveform?

I looked at your website. Are you serious? Or is it intentional word wuze? I ask because it IS word wuze. You are using words without any fact based meaning attached to them at any time. "ZPE spin momentum singularity" is about as meaningless a noise as I have seen on this site. Even the AWITBS crap has more relevance to reality.

Words exist to communicate about facts and ideas. When they are detached from the facts or the original ideas they were created to communicate about they no longer have any meaning. For instance

Spin momentum singularity has NO meaning at all in a single point. Spin in the sense of angular momentum only has reality in comparison to the rest of the universe. Without OTHER objects there is no angular momentum. GR shows this and so far the evidence supports this.

Please try to attach your concept to FACTS so they can have some meaning. Spinning out meaningless words just to fill space is a waste of time or change in terms of this article

You imagine sitting with your son or daughter on the sofa and discussing on time. As a physicist you are aware you sit inside a quantum vacuum made of out QS volume of Planck. Inside Volume of Plank there is no change and so no numerical order of change. Change and numerical order (time) start at scale of Planck. In quantum vacuum before, now and after exist only in a sense of numerical order, means duration of an event is exclusively a mathematical quantity. From this perspective your life is longer than the life of your child but only in a mathematical sense. From this perspective universe age has only a mathematical dimension. In Princeton Einstein and Gödel has been discussed walking back home about universe without time.

In dense aether model of space-time with water surface the space dimension corresponds the direction parallel with water surface, the time dimension corresponds the direction perpendicular to water surface. It explains, why we can move in space easily, but not in time. And it illustrates too, why time always has an arrow (density gradient) assigned, whereas the space not. The removal of time from physics may solve some isolated problems, but it will bring a much more problems in another areas, so it's not advantageous from utilitarian reasons.


Fish can move through Water-space the same way that Heavenly-objects and space-ships can move through Space-space.

As for Time, we do move in Time (positive increments only) but not fast enough to get anywhere quickly.

Time is an element of the vector[] to determine the relative position of one object to another. It cant be absolute bc we dont know where we are; we have no knowledge of what is where.

An experiment which proves duration of an event is not a physical quantity. You walk on the street 3,6 km. You need 1 hour to pass distance of 3,6km. Distance is physical quantity, duration is not because you do not walk in time; time is only a numerical order of your walk. 1 hour is 3600 seconds. Each step takes 1 second. 3600 seconds is a number that shows you numerical order of your motion on the distance of 3,6km. Same is with the fish moving in water.
We do not remove time from physics, we just give it right meaning based on experimental facts.

Expect discourse. Our "walk back home", in all fairness to your concept and point of view, deserves a length of duration,

Emphasize the "Race course" paradox and your solution. De-emphasizing 'time' and emphasize the 'mathematical sense' of numerical order - an intuitive approach that helps children of all ages(!), to grasp this.

@Eth: Amrit Sorli is one of the authors of the paper. Do a Google Scholar search to look at some of his work. Based on what I read and his profile here I think this might be him.

@Amrit: Three questions.
(1)What are your thoughts on CTLs being allowed in GR as shown by Godel?

(2)Do you still believe, and if so how do you support? (ref 58J-2010-04-xx-01):
The process of continuous creation of particles in outer space increases the presence of mass in the universe, ends expansion and starts contraction.


(3)Also, regarding gravity, without gravity waves, does your theory lead to FTL gravitational effects?

So you know, I have a real problem with the two times in GR. My belief (intuitive only) is that CTLs are an artifact of the incompleteness of GR and that an enhancement of the theory is needed. (Godel pun intended, though everyone hates it when I do it.)

From the website
For us, human beings, this means: the universe is an eternal here and now wherein time measured with clocks is merely a numerical order of change.
I don't see any value of simply replacing time with change. Change can't occur without time or time can't occur without change, though I am not sure about the latter. If there is no difference in the math except the labels why the effort to claim there is no time?

merely a numerical order of change.
Vs merely a numerical order of TIME. One is a meaningless replacement and the other fits human thinking.

Pyle if you saw my posts on MultiVerse and Math concepts you will note that in those time is just a numerical order. Which I find disturbing but I can live with it since it explains why something instead of nothing.

I think it is silly to replace the word TIME with CHANGE for no increase in understanding, or an improvement in the math or any predictions proceeding from the idea.

Playing games with words is a bad sign. Words describe facts for the purposes of communication. If all you can do is change the words you are not dealing with facts and are trying to use Proof by Definition to AVOID possibly inconvenient facts.

'Time is physical quantity, distance is not because you do not walk in space; position is only a numerical order of your walk through time.'

See what happens if you just replace words instead of dealing with facts?

'We do not remove position from physics, we just give it right meaning based on experimental facts.'

And again a simple replacement of time based vs your position based thinking shows that you are simply playing word games.

Time and Space are DIMENSIONS. The math using those dimensions WORKS. That no one understands time fully is a result of it simply being a property of the Universe just as Space is. We don't understand the why of space either but we have an intuitive ability to deal with BOTH despite that, probably because we evolved under those conditions. That Time and Space are interlocked in SR and GR is not intuitive because we cannot travel in time with same freedom as we do in space.

Either way they are just dimensions. Changing the labels without something of value coming from it is silly.

This is an old argument.

"Two contrasting viewpoints on time... One view is that time is part of the fundamental structure of the universe, a dimension in which events occur in sequence... The opposing view is that time does not refer to any kind of "container" that events and objects "move through", nor to any entity that "flows", but that it is instead part of a fundamental intellectual structure... within which humans sequence and compare events. This second view, in the tradition of Gottfried Leibniz and Immanuel Kant, holds that time is neither an event nor a thing, and thus is not itself measurable nor can it be travelled."

http://en.wikiped..._physics

Personally, I subscribe to the former view. The reason being; the only numerical sequence of events time is really tied to, is the speed of light. That is, every other sequence of events is relative to the speed of light, as observed locally.

Perhaps the wheel began as a primitive notion (disregarding the oxymoron content) as well.

Sorry everyone, I was a bit rushed yesterday and quite vague if you weren't me. Yes, by CTLs I meant Closed Timelike Loops, or Curves I'll use CTCs going forward. Godel showed that a universe was possible that was consistent with GR yet contained these CTCs where one could revist their past. Subsequently the exotics have been linked to CTCs, but my understanding was that Godel universes are just rotating with some special distribution of normal mass. Red shift data seems to indicate we don't live in a Godel universe.

Anyway, this idea of time being a numerical order of change is nice, but it doesn't deal with relativity so it seems pretty 19th century, as everyone has been saying. uba nailed it I think.

I'm with uba on this one. Time is relative. I don't think there is confusion in this statement. Yeah, yeah, yeah: time, space, space-time. Distance is relative too. So there Ethelred, thpppt! The measurement of spacetime, albeit length or duration, is relative to the frame of the observer.

In physics time is a mathematical tool which help us to describe physical phenomena. Time is not relative, relative is velocity of material change. And "relativity" starts with massive particles; light has the same speed in all inertial systems, so no relativity by light, see our coming article "The now insights into the SR" - Physics Essays - AIP.

Movement in Space-time has a fixed total. More movement in one means less in the other. Not thinking about it this way may be what is causing you guys to argue about it being relative or not. The total movement in all four dimensions is always the same. And yes it is relative. If nothing else movement in space-time is relative to the Universe as a whole. But you always move in space-time not just one dimension.

Not really. GR works NOW. The rules might have been different in the first fractional moments of space-time. Most physicists are certain that the quantum rules were different IF there was BB. In Brane theory I suppose that would be different.

What I was trying to do is get people to think about space-time as a whole and not separate elements. Sometimes if you can change point of view you gain in insight. Sometimes you start haring off into the wilderness and never return. See Oliver K Manuel for an example.

In physics time is something we use because we experience literally every instance of our existence.

No. First it is speed, a scalar, and not velocity, a vector. Second both speed through space and time are relative to observers or the Universe as a whole or your point of origin if it is YOUR speed that you are dealing with.

And "relativity" starts with massive particles;
Well anything with mass OR without mass.

The redshift effect is still relativistic and NOT Newtonian.

It the Universe is more than 4D, space-time IS 4D not 3D, then any instruments we make are inherently more than 4D. The key is making instruments that can detect that. We can detect the curvature of space for instance. That is likely either occurring in a yet one more dimension or there is some kind of granularity of space and those grains are of variable size.

The Tortoise paradox does not account for time in a correct manner - Achilles is not being granted the sufficient PERIOD of time needed in order to pass the tortoise. IMO this is a simple and straightforward explanation - it would have been a paradox if Achilles under the given conditions was capable of overtaking the tortoise !

That said: - In order better to understand the concept of timeless Universe - IMO it should be stressed that Timeless Universe must refer to "Noumenal World" out from which "Fenomenal World" is being "extracted or interfered with" by human mind and translated into this vivid impression of a "Real Physical World". In this perspective Noumenal Universe is timeless - and time can be defined as the order of material change in physical world - HOWEVER nothing is being said about how to define MATERIAL CHANGE ! What is changing ? IMO it is the mind (the observer) that integrates the "timeless events". This implicate that Time become a mind-related quality.

Temporal and Atemporal View in Physics
The existing temporal view in physics sees material changes taking place in space-time as a fundamental arena of the universe where time, past-present-future, is seen as the fourth dimension of space-time. This temporal view is the result of experiencing material changes within the framework of linear time, past-present-future, which is the fundamental psychological model of the mind through which an observer experiences the material world. In universe there is no linear time as a dimension of space. Quantum space is 3D (Planck Volume is 3D) and time t is a numerical mathematical order of material changes in a 3D space. This atemporal view is closer to the real physical world as the temporal view. It gives us a more adequate picture of physical reality; it is based on the observer that is conscious of his/her psychological time.

Amrit, thanks for responding. Sorry for my first comment not being so serious, as I did not anticipate you would take part in the discussion; though I'm glad you did.

I'd like to ask you one question. I get that you regard time as an ordering and not an axis through which particles travel. But locally, from the point of view of a particle and in its vicinity, taking that ordering of events that it encounters (t1 < t2 < t3...), shouldn't that total ordering implicitly define a field?

http://en.wikiped...ed_field

And so, conceptually it defines a space, a 4th dimension.

The question of whether such a dimension is "instanced" and fixed already (static Universe) or whether our Universe's rules destructively "update and replace" space as events happen is more of a metaphysical one (ie, "implementation details") and can't possibly be answered, so I don't mean to go there.

idknow, you wrote: "Time and Distance are the same thing from different perspectives, measuring the same thing with different scales."

Can you elucidate? Consider human conception. Prior to the conception, ovum and sperm occupy two unique spatial locations (non-coincident). The sperm could pass through a specified location (at one time). And, the ovum can pass the same location earlier (or later). While within parents, the two cannot occupy the same location simultaneously (without a consequential mess). Yet, once fertilized, the two do occupy the same location.

The distance between each of the ovuma and sperm (and the location of interest) can reduce value magnitude to zero. But, while in the two parents, the zero distance cannot be simultaneous. At fertilization, they do. I argue that distance is not the same as time, and time is independent of it. The 3D+T does exist as 4D universe. [I postulate another dimension - thought. Encompassing reality or fantasy, time separates.]

We have, so far, demonstrated General Relativity to be an accurate theory to predict and explain observations we make in the physical world. If you don't "attach" it to the physical world it is just a set of equations. Now, if you are referring to the problem with finding the physical "cause" of relativity, that is where if these guys are right we would need to adjust GR since it allows for CTLs and the like. The rest of what you say is just babble.

I guess I tuned out after this, but the conversation continues. We still exist in the present, but the earlier posts are fading into the past. The present doesn't move along some external dimension, it simply changes form and those areas with higher levels of activity change faster than those areas with lower levels of activity. Acceleration and gravity will slow rates of change. Probability precedes actuality. Future events become past events. This effect of time is relativistic, but it is still contained by what is physical.

Regarding calculations of relative rate of clocks in GPS we have to impact: one of SR and one of GR. Special Relativity predicts according to formalism (2) that the on-board atomic clocks on the satellites should fall behind clocks on the ground by about 7 µs per day. A prediction by General Relativity is that clocks closer to a massive object will seem to tick more slowly than those located further away. As such, when viewed from the surface of the Earth, the clocks on the satellites appear to be ticking faster than identical clocks on the ground. A calculation according to the formalism (3) predicts that the clocks in each GPS satellite should get ahead of ground-based clocks by 45 µs per day.
The combination of these two relativistic effects means that the clocks on-board of each satellite should tick faster than identical clocks on the ground by about 38 µs per day.

There is little in physics above the quantum level that is not dependent on time. Even at the quantum level there is time. There just isn't an arrow of time at that level. So far nothing you have said is in anything except word replacement.

And the fact that the math works.

Nonsense. The mind is biological and chemical. It functions according to the laws of the Universe and it evolved to fit those laws. Psychology is the study of the mind and NOT a process of the mind.

Ethelred,
It's a question of whether time is a dimension along which events exist, aka. blocktime, or is time the rate of change, due to constant activity.
The difference is that in the first, the events and this dimension, are the constant, while the point of the present moves along them. With the second, the present is the constant and it is the events which coalesce out of probabilities and are replace by the process, such that it is the events going future to past.
While the entire basis of history and cause and effect logic are the direction of past to future, in order to create a physical theory to explain it, relativity uses the correlation of distance and duration to argue space and time are equivalent and the present is an illusion. While QM uses an external absolute change of instant measurements. The result is by projecting a deterministic past onto a probabilistic future, they end up in multiworlds.
On the other hand, if time is simply a collapse of probabilities, as the
brodix
3 / 5 (5) Apr 30, 2011
physical reality evolves and is the future becoming the past, it retains the present as fundamental and allows physical laws to determine the course of events.
Also it retains free will, because if time goes past to future and we only exist at the moment of the present, then we can neither change the past, or affect the future, but if time is an effect of motion, then our input is integral to the events being created.

This is still living in time. A numerical oder of change that fits the physical laws of our universe is indistinguishable from time. It is not in our head that light has specific frequency of oscillation per unit of numerical order.

A and B are indistinguishable. Though A, as stated has the advantage of fitting GR and B is simply the product of you not understanding that a numerical order of change is still the same as A and thus the only thing wrong is your insistence on avoiding SR and GR which have space-time.

QC,
The foundation which any social organization requires is a group narrative. Polytheistic societies were generally competing groups of people, owing allegiance to differing ideals, as well as recognized powerful outside forces. Those most focused on one deity proved far more political effective. There is a necessary tendency for such identifications to become increasingly hermetic and deny any reality that is not also centered around their deity. That such belief systems develop idiosyncrasies is not a bug, but a feature, as it separates true believers from those harboring doubts.

There is no space without time, as much as there is no time without space. Those two are inseparable, and represent not two, but ONE physical entity - which is being refferenced to as "space-time" by some.

When you travel through space, you also travel through time, and vice-versa. And as much as you can not travel a negative distance, you neither can travel "back" in time.

Everything in the Universe is in constant motion - there is no such thing as an "absolute standstill". Even though some of the outcomes of classic GR and using its maths might suggest otherwise - the problem is mostly not within the concept, but with its application. You have to treat space and time as one entity, and only then you can understand that the actual absolutes (zero/infinity) will actually never be reached. At least not within a sub-group of the absolute (the Universe).

And as such, I also have to jump on the boat which suggests that there is no separate entity "time". If, then only space-time.

- in which way?
The concept that time is merely measuring a numerical sequence of events, does nothing to explain time dilation.

As the speed of light constant is a fundamental property of spacetime, and clock rates are inextricably tied to the locally observed speed of light in a vacuum, time itself is a fundamental property of spacetime.

Otherwise, processes which change numerical sequences of events (like heating, or freezing), or even change the propagation speed of light (like through various materials), would have an effect on locally observed time.

Very simply, it doesn't matter whether time is a physical dimension or not. It wouldn't turn the world of physics upside town if it wasn't. Very very little in physics depends on time. Even though some equations use time, those equations don't depend on time; they could replace time with something else or rather more frequently make due without time at all. "Time is simply an illusion derived from motion. If nothing could move, there would be no time. Of course, human beings being creatures of evolution could argue time goes on even if there is no motion, but this is a contradiction for time implies change and without motion there can be no change. Therefore, time is simply the bi-product of change, and not an independent entity."

Force is not even correctly defined. Force is defined in terms of mass, and mass in term of forces they dont exist its all geometry.

Correct. Geometry is what accounts for all differences from any entity to another entity. Whether they be objects, forces etc... Geometry is what makes unlimited creation possible.

Chiefly of interest in these findings, IMO, is the fact that some barriers to certain types of phenomena will be removed -a good example being the possibility of Quantum-entangled states being able to transmit information over large distances --instantaneously, in fact-- as the idea of FTL travel will cease to have any relevance as a fundamental impossibility. No time = no theoretical limit to velocity.

I'm sure there are plenty of other assumed impossibilities that will be possible with this new understanding, but that example came to mind first.

With spacetime, the aspect of space being considered is distance. Yes, any motion across distance requires duration, but another aspect of space is volume. We generally accept that space cannot exist without containing some amount of energy, so it would have to have a temperature. Such as the temperature of the CMBR at 3.7k. If you use ideal gas laws, temperature and volume are inversely proportional; Reduce the volume of a given amount of gas and the temperature rises proportionally. By the logic of spacetime, wouldn't temperature be another parameter of volume? Yet we don't talk about spacetemperature. Why not? Yes, they are fundamentally related, but we recognize there are differences.
The reason we equate time with space is because we really don't understand time, so we equate it with motion through space. It defines our life, yet seems ethereal. The future is unknown and the past seems both objectively precise and subjectively fragmentary. Is it coming, or going?

Very very little in physics depends on time. Even though some equations use time, those equations don't depend on time; they could replace time with something else or rather more frequently make due without time at all.

Perhaps Amrit had de Sitter Space in the back of his mind.
Conceivably after having read the following statement:

"Since the spacetime metric has no explicit time dependence, once an observer has crossed the cosmological horizon, observers closer in take its place. This ...process of ...an exponential expansion of spacetime."

"This steady-state exponentially expanding spacetime is called a de Sitter space, and to sustain it there must be a cosmological constant, a vacuum energy proportional to everywhere. In this case, the equation of state is p=-rho."

Wikipedia: Inflation(cosmology)
Subtitle;
Space expands. (Directly after subtitle 'Overview'.)

It is not as if this suggestion - that space-time has no time dimension - has not been already been discussed long ago.

"FTL travel will cease to have any relevance as a fundamental impossibility. No time = no theoretical limit to velocity." - Whatever

You read but don't comprehend. The claim isn't that time doesn't "exist". The claim is that time doesn't "exist" as a physical dimension.

And of course, it doesn't.

Like temperature or entropy, the concept of "time" is an emergent characteristic of a bulk collection of objects.

The fact that time has an apparent geometric relationship with space is an artifact of analysis. It need not and does not have any real geometric interpretation. The apparent geometry of space time is a contrivance which may aid in the visualization of the relationship between space and the bulk property we call time, but simply because there is a mathematical relationship between space and time that is the same as a geometric one, this doesn't require that the relationship have any true physical manifestation.

Time is obviously an emergent property of a bulk, because without objects that change relative to each other, there is no concept of time. Time is always defined in terms of relative change. That is object A is seen to evolve relative to system B which is taken to evolve at a known rate. Hence a relative rate of change for A is implied.

There can be no time evolution to an empty universe.
There can be no time evolution of a universe consisting of a single particle.

The same is true even for a universe consisting of 2 particles since time must be defined relative to an evolving system and there is only one system evolving and no observer available.

Time only has meaning in a universe of 3 or more particles and even then time evolution is curious.

Consider a 1 dimensional universe of three particles A,B and O (observer). Configure the universe so that it progresses from left to right as ABO. Define that as T=0
Now allow the universe to be configured as BAO This is T=1

Vendicar_Decarian
not rated yet Apr 30, 2011
But suppose A and B are oscillating between AB and BA. Then O will see time evolving as 0,1,0,1,0,1. Time will shuttle back and forth, sometimes going backward.

As the number of particles in the universe increases, it becomes increasingly difficult for a system to evolve naturally into a state it acquired earlier. So with larger systems time seems to never return to an earlier state and hence never appears to go backward.

Time is in fact governed by the same statistical properties of entropy, and this is why the entropy of large bulks strongly tends to increase over time. It does so because time is ultimately defined by the bulk characteristics of the entire universe.

Vendicar_Decarian

To an observer deemed "outside" the universe, time travel is possible. But only by re-arranging the entire content of the universe into a state it held earlier in "time".

If the observer is deemed "inside" the universe, then time travel is also possible by doing the same as above. But in this instance the observer must be part of that which is being re-arranged.

By doing so however, the observer loses all memory of it's regression in time, and hence can never "experience" time travel.

You may have gone back in time just a fraction of a second ago, but you would never know it because your memory of the present was erased as the universe reconfigured itself, and the universe includes your memory of the current state.

As to faster than light travel... That will never be possible because the objects are in large part comprised of electric fields, and since the propagation speed of electric fields has an upper limit of c then so does everything that is in part composed of an electric field.

On the other hand, I have seen no convincing argument preventing faster than light signaling, provided that those signals are not carried by an electric (electroweak) field.

Should physics manage to unify all fields into one, then it is likely (but not required) that there will be a common propagation speed limit to all of it's derivative components.

This is the notion that an astronaut traveling near the speed of light would age more slowly than those at rest on earth -- proven by experiment with atomic clocks on spacecraft. But it's one-way, and not really "travel."

Back-and-forth travel to the future is impossible, because there's no "future" to travel to. By whatever means, slowing down the aging process just allows one to stay young longer in the present -- the same present in which others age more rapidly. This already happens with the disease progeria, in which the aging process is accelerated. If you met a progeria-stricken child when he was one year old and only saw him again when he was eight but had aged to eighty, would you say you'd traveled to the future? How would this be any different than when a spacetime traveler returns to earth after fifty years to find he's still young and his son is an old man?

Hi common idea is time is physical, time is dimension of space.
Not just common. It is part of GR and SR.

Our idea is time has only math status, time is a mathematical numerical order of change in space.
Except that the math is still identical thus there is no difference.

if you do not see difference here, fine for me.
I am asking what the difference IS since YOU JUST SAID it is mathematically indistinguishable.

A numerical order of change that fits the physical laws of our universe is ((indistinguishable) (from)) time.
Since there is NO WAY to distinguish, if it cannot be distinguished mathematically then there is NO WAY to distinguish AT ALL so WHAT IS THE POINT.

Avoiding the question is not helping anyone.

It looks like you're essentially saying your motion sets the clock rate, without regard to time dilation and reference frames.

If motion alone represents time, why do different observers observe different clock rates, when observing the same set of numerical sequences? Is it magic?

The problem in understanding time here is, it's not your motion which sets the clock rate, but rather it is the speed of light relative to your frame of reference which sets the clock rate. Do you see? Time is about the spacetime around you, not numerical sequences of change, per se.

clocks "tick" in space only, not in time,

The only reason there is any confusion as to the nature of time is that we tend to view it as the present moving from past to future in a linear fashion. Which does make it seem similar to space. Note the use of lightspeed is to convert distance and duration.
If we view the present as the constant and it is the changing configuration of this physical reality which causes future potential to coalesce into current form and then be replaced by continuous change, it is a non-linear process, much like temperature is a non-linear scale. The vector of time is effect, not cause.
On the other hand, what is space? If you had a single object and no external reference, presumably spin would still be apparent, because it would exert centrifugal force.
Space would seem to be an equilibrium state and that might be the reason for the consistancy of light.

If I was on an astroid in intergalactic space, then the only way to tell if it was spinning was by observing galaxies in the far distance? What if I was blind, then would I be safe, but if I could see, I would be spun off?

No. Green is an emergent color when one mixes blue and yellow.
When mixing pastels, sure. But in reality, green is a real part of the spectrum and is a primary color (used in CRT's and projection equipment). So your perception of green in pastels is an emergent perception only. It doesn't make green any less real.

Actually we can manipulate time for isolated systems in an exactly analogous manner. by simply returning a sample to the state it was in before now. The universe has moved forward in time, but taken in isolation from the universe, the sample has moved back in time.
No, this would be an example of, well, change.

The information regarding the changes has moved on to other sources, but it exists, nonetheless.

There can be no time evolution of a universe consisting of a single particle
What if the particle is a neutron? Would it not decay? What if it's a photon? Would it exist, or merely be a hypothetical potential?

On the very small scale, space isn't all about the objects in it. Space is also its own thing (quantum fluctuations) and therefore can exist separately from the objects within it.

As virtual particle interactions are time dependent, in an "empty" spacetime, time should still exist (even if only as an abstract principle).

So even in QM, time is a required property of spacetime.

Almost everything said about color has been wrong. Red or Green? Wiki Qualia. The brain calculates the color from the sensory signals from the eyes. This is essentially a calculation of the color and not just a response to a specific wavelength.

For example, notice how film records light changes with great difficulty when going from indoor light to outdoor light. The eye adjusts for all of this on the fly and we see persistent shades of color even in changing lighting.

While typically a human eye has sets of three cones with different sensitivities, some people have four and are capable of making more subtle distinctions. (wiki Eye)

Further there is research which shows that color perception is also affected by language.

In terms of "mixing" colors almost any three colors properly separated (generally equally) on the color wheel can be adjusted to produce white and the intermediate color mixes.

Color perception and color science is a complex topic.

Your question is one that has been first accredited to Mach. You have been imprecise in it's asking however.

Observation includes more than just seeing. An observation is any interaction you can have with another object or system.

I may not see an electron, but I can experience it's charge. That is an observation.

Similarly, I may not see a remote galaxy but if I feel it's gravitational tug, or if photons from it strike the back of my head, then that is also an observation.

Now, if I am isolated from the rest of the universe in such a way that there is no outside influence on me at all, then such an environment should be identical to a situation where I am alone in an empty universe.

The best way to understand time is to think of it as a "Ruler". Time is simply the measurement of change. just as inches are a measurement of length. Neither time nor inches exist as dimensions, they only exist as tools for us to apply to bring understanding to something that is dimensional. Thats why I believe time travel is impossible.. We can only effect the rate of change we are in, not time itself.. and the closest way to connect with the past is to put yourself closest to the point of occurrence. So while time travel is impossible, with all the technology we have now, we are connecting ourselves to current events faster. Which in essence will be as close to past time travel as we are ever going to get..

Vendicar,
Much of current cosmology is based on the assumption that the four dimensional fabric of spacetime is as real as those giant cosmic gear wheels of epicycles were assumed to be. Once you propose that it is simply a mathematical model and time is not a real fourth dimension, then the whole Big Bang/Inflationary cosmology concept evaporates, because space has no physical manifestation and so cannot be warped, bent, bounded, etc.
Consider that while this expanding universe is based on the redshift of light and the assumption that the only cause can be recession of the source, this raised an initial problem, because if it is essentially an expansion in three dimensional space, we would appear to be at the center of the universe. So it was amended to say that space itself expands multidimensionally and every point appears to be the center.
brodix
1 / 5 (4) May 01, 2011
The problem is that the speed of light is stable. This means the space it crosses is stable. Redshift could very logically be an effect of distance, since it is mostly proportional to distance.
Inflation and Dark energy are enormous patches proposed to explain discrepancies between theory and observation. These observations could easily be explained by various aspects of a stable universe, in which the facets of collapsing mass and expanding energy make up a cosmic convection cycle.
One of the main evidentiary proofs of Big Bang theory was the discovery of Background radiation, combined with the prediction that it would exist as residue from the singularity. Yet if light travels so far it falls off the visible scale, then it would register as this black body radiation. So instead of an initial effect of the Big Bang, it would be the final effect of some form of "tired light."
brodix
1 / 5 (4) May 01, 2011
This then goes to the nature of light and whether photons are irreducible units, or the smallest measureable quantity of light; that which will bounce an electron to a higher orbit.
Not to start arguments with convention, but I suspect many of the current assumptions are a patchwork that are not going to stand up to a lot of further evidence. The oldest observed galaxy is at 13.2 billion lightyears and that means something that large had to coalesce in just 500 million years. Given it takes our own galaxy 225 million years to make one revolution, that is a very short amount of time and will eventually seem as likely as a 6 thousand year old earth seems today.

"Isn't it interesting how a linear arrangement of frequency is perceptually converted into a 3 dimensional volume"

Actually a 3D point. The original wave is a linear combination of an infinite number of frequencies, our eyes just sample 3 of them - it's a compact representation :)

"t can always be replaced by d/c for a reference light beam."

Surely you can't just make that substitution. These "d" and "t" are different, independent quantities. You can't just specify one as a function of the other, you need those 2 degrees of freedom.

"not at all: in every equation of physics time t is exactly numerical order of material change"

In that case, Ethelred was right and time versus change is just semantics. Of course the same concept can be interpreted in multiple ways. A wave can be interpreted in time or frequency, as above. It doesn't make sense to say one is truer than the other.

"by gravity there is no numerical order (no time)"

Yes, some forces are independent of time/velocities.

It is all the result of the quantum vacuum.

Gravitation increases the local vacuum energy.

As a result light passing through a gravitational field experiences more quantum scattering and hence takes longer
to traverse a void.

Since we define c as being a constant we conclude that the longer traversal time implies more space. So we conclude that there is more space the closer we get to a gravitating object, and that space is "warped" around that object.

It's possible to think that physical phenomena associated to materials bodies are dominated by time, as the fourth dimension of space (4D).
But the human perception of time, allows us to perceive the time as a dimension independent 3D + t. In some subjects the perception of past events, or sequences of past events and, sometimes, of the future, is just as "alive".

I don't think that a complete description can fit in 1000 characters.

Less spatially dense relative to a uniform grid imposed on space from a sufficient distance away such that space can be presumed to be flat.

Rulers contract when moved into stronger gravitational fields. This clearly shows that the stronger a gravitational field, the more space and more vacuum energy there is associated with it.

In reality, this additional space is a result of the larger transit time through a region due to the higher vacuum energy.

The additional vacuum energy is the self energy of the gravitational field.

Gravitational fields are attractive because there is more space below an object than above, hence quantum mechanical fluctuations in the objects position have a higher probability of occurring below than above.

There is a difference between past, present and future, and it is all a result of the increase in the entropy of the universe.

It would be a very rare event for a system to have a memory of it's future because it's future would have to be in it's past, along with the memory of that future.

Since the probability of such a system is exceptionally low, the probability that a system can't remember it's future is exceptionally high.

Since he was the creator of quantum electro-dynamics I have to suspect that magnetism may be a real force and not a fictitious force like centrifugal force.

Sometimes looking at fictitious forces and comparing them to what are considered real forces like gravity leads to a deeper understanding. Which is why I am saying that gravity itself is a fictitious force. I am beginning to wonder about electromagnetism as well.

Actually green is in the spectrum as well as by mixing blue and yellow.

Now PURPLE is really weird.

Gravity does contract "space," yet space expands between gravity fields and the combined effect is neutral, ie. overall, space is flat. Currently this is being explained by Inflation blowing the universe up so large that its overall curvature isn't apparent, but a cosmic convection cycle would explain this relationship far more efficiently. Recently Paul Steinhardt, one of the developers of Inflation, raised serious questions about it creating more problems than it solves, in a cover story in SciAm.

If the universe expanded from a point, then why is the speed of light constant? The Doppler effect isn't about expanding space, but increasing distance. The train moving away doesn't create space, but moves through it. Same for galaxies: If they were x lightyears apart and then they are 2x lightyears apart, that is not expanding space, just increasing distance in stable space.
Geometry assumes zero is the center point, but logically it is the empty page. A point is one, whether it's in the center, or anywhere else on the page. Moving the points around doesn't create the space, just defines it.

Try the word 'Nature' instead of 'entropy'.

As far as Nature is concerned, all of Nature can be defined by the way it distributes energy introduced to it.

Of course energy is timeless. The distribution (of energy) is the "shape" (or "structure") you call memory. Or perception. Or Mind. Or Math. Or Time. Or Space. Or Event. Or literally everything.

The only limits to the ways of distributing energy are the limits you impose upon yourself. And the most important limit facing everyone today are our languages - used to describe Nature.

99% of what we read, write or say, are descriptions, not definitions or rules. You want to know the origin of all our 7000 languages? That all started with perceptions. Our senses, the origin of our jump start cognitive supremacy over other evolutionary forms of life.

"If the universe expanded from a point, then why is the speed of light constant?" - Brodix

The speed of light isn't constant. It varies with the energy density of the space it travels through.

The speed of light in a vacuum is thought to be constant, but we don't know if this is even approximately true in the earliest moments of the origin of the universe.

I expect that c goes to 0 as t goes to 0. But then the high gravitational forces cause d to go to zero as well.

Which makes it there first? c or d???

"Gravity does contract "space," yet space expands between gravity fields and the combined effect is neutral, ie. overall, space is flat." - Brodix

Correct. Gravity manufactures space, and packs more of it into any given volume as defined by extending a Cartesian coordinate system from an area of lower gravity.

Since gravitational field strength corresponds with additional space, objects must compress as seen from areas of lower gravitational strength.

Isn't RAM and ROM a form of memory distinct from the human mind?

"Mathematical formulas do not express the memory, so why the arrow of time must necessarily point to the future?"

I haven't seen that video, but so many of them have been pulled from circulation over the last couple of years so that access to them can be sold.

Feynman knew full well that all magnetism with the possible exception of quantum spin moments are the result of relativistic electrostatics.

Spin is a special case since electrons seem to spin, but have no internal structure to support spin. Hence their magnetic field would appear to be fundamental.

I suspect however that their spin is really due to an unequal flow of virtual particles around the charge imbalance. Such a flow is probably required to keep the charge imbalance from disapating.

You can't unify something that doesn't exist.

"Gravitational fields" are attributable to the local change in vacuum energy density. Higher density equates to a slower transit of light, and therefore an an apparent compaction of objects, an increase in space, a slowing of the flow of time, and as a result of the reduction of local entropy, the opportunity for local objects to increase the entropy by diffusing along the density gradient.

The difference of course is that no one claims that temperature is the 4th dimension.

@ Hush1. Certainly the problem of language to describe the nature and human events is a big problem. Just read Wittgenstien, to name one.
But if the energy is timeless, while the distribution of energy is "form", or structure, Levi-Strauss docet., in a sense, it is as if there is a jump from "Being" to "existence"(event )? From non-being to being? From time to time-not?

@ Vendicar. The difference between the shape of human memory and that of a RAM? Maybe it's the difference between memory and storage. A RAM stores, can not remember, the human mind stores and recalls at memory. The act of remembering seems to have an extra step, it is said that to remember is to report to memory (in the present) the past and not only what is stored. In RAM there is no past, there are only data.

Please, if I go too off-topic, tell me.

Time is merely the sequence. A clock creates a reliable, repetitive event system with which to compare the sequence of other events. One cannot perfectly synchronize different clock frames because they are both creating their own references. It has nothing to do with space. It isn't really all that complicated when you stop trying to explain how everything came from nothing over time. Order comes from randomness, not nothing. Order occurs randomly. That it does so over time is a simple cause-effect relationship. Stop trying to divide by zero: there's nothing there to divide with.

Ethelred is not alone. The name change has to be a rose. Putting aesthetics aside.


If you view the present as moving from past to future, time is a vector, similar to direction in space, but if you view the present as a dynamic state, in which potential coalesces into actual and it is the events which move "through" this present, from future to past, then it is a thermal medium and duration/rate of change, is relative to the processes enabling that change.
Because we can only exist in the present, our senses record the series of events, but then our senses also still see the sun as moving across the sky and our bio-rhythms are still very tuned to that.
The problem was developing a physical explanation for the sun's movement, much as developing a physical explanation for the present moving along the path of history is proving difficult to explain physically.

You keep saying "opens new understanding" and the like, but as Ethelred keeps asking: HOW?

If you uphold the two assertions/assumptions that energy is timeless and infinite in form, you need a construct/concept/tool/description, that meets and provides the sum of our data, information, experience, knowledge and existence.

Worst still, once that sum is successfully provided and described, we expect that sum to render our understanding of time as obsolete. The sum has to predict, as well as, repeat 'something' that is timeless and infinite in form.

The tool 'Spacetime' falls shorts in describing and providing the 'sum' described above.

The tool 'Numerical order of change in space' is like metaphorically looking at twins when regarding both tools.
I am not the Mother. I can not tell them apart. You can. And assert this tool provides and describes the 'sum' described above.

Wow. You obviously don't understand time dilation. Time and the speed of light are inextricably linked. No observer can ever see the speed of light in a vacuum change. However, distant observers can see a similar effect caused by time dilation. It's why black holes have the nickname, "frozen stars."

"Oppenheimer and his co-authors interpreted the singularity at the boundary of the Schwarzschild radius as indicating that this was the boundary of a bubble in which time stopped. This is a valid point of view for external observers, but not for infalling observers. Because of this property, the collapsed stars were called 'frozen stars,'"

Elisan,
Energy and information are two sides of the same coin. Energy manifests information and information defines energy. Since the energy is conserved, as new information is created, old information is erased.
When we are observing something at a distance, we are receiving the information carrying energy and interpreting it according to the patterns manifested in our mind.
As for time, the energy goes from prior information configurations to succeeding ones, while the information becomes manifest and then is replaced. So energy goes past to future, while information goes future to past.
To the extent our brains are physically manifest, they proceed from past events to future ones. Our minds are a succession of thoughts, which coalesce out of received information and then evolve into, or are replaced by the next thought, depending on our level of concentration. So the brain goes past to future, while the thoughts go from being in the future to being in the past.

c is determined by the scattering density of the particles that compose the vacuum. Increase their density and you increase the number of scattering events and in one view you decrease c.

In another view if you presume that c is a constant, then you have manufactured space since the transit time through a volume has increased, and the distance traveled must have increased in order to keep c fixed.

"Next, you'll tell us about "zero point weather" - as energy invariably flows from higher to lower potentials!" - Ubavon

The value of c is determined by the amount of scattering a photon experience while traveling through space. Between scattering events c is infinite, but emission delays within the scattering events themselves reduce the effective speed to c.

The measurement of time is arbitrary, really.
Why do we say hours, seconds? Why do we divide a day into two: day and night?
Why do we say that the solar revolution takes 1 year?, 12 months?
We could use another unit, that is a fragment of different "time "? Is time only different states, ie spatial positions of the earth to the sun.

The catch is I can't figure out how to use topology for both gravity and acceleration even though they are indistinguishable or rather because they are.

"My brain hurts."
If it helps, it's only indistinguishable in a sealed room. If you can look out (particularly "under" your floor), it rapidly becomes apparent you're either on a planet, or accelerating.

That is, they aren't really indistinguishable in the broad sense, but rather only in a narrow sense.

An aside: Awhile back, I described methodologies wherein a sealed room observer might tell the difference between acceleration and resting on a planet, through experimentation. The caveat was, the sealed room must obey all the laws of physics, save being able to perpetually accelerate. It was a fun brain stretch.

Temperature is the mean energy of MOTION. At thermodynamic level we assume the " system" is changing over time from one equilibrium state to another equilibrium state and that is how we get rid off TIME in the equations but is still there implicitly. There will be no system evolution if no time. One single configuration of the system is a snapshot in time of the system.

WHAT THE BLOODY HELL MAKES YOUR IDEA WORTHWHILE SINCE IT IS NOTHING BUT PHILOSOPHY?


It does sound like just moving the units around in the equations without ever changing the math, but the change in viewpoint has helped me, I think. Again, I'm a complete novice, but I've always had trouble seeing how anything was actually explained by the idea of a gravitational field as a surface that can be depressed by massive objects.

This article led me to think of space as a (very large) set of (very tiny) volumes (Planck distance cubed?), with photons hopping from one volume to the next, but never being able to move any shorter distance than that. If c is still the cosmic speed limit, then the existence of black holes means that space has to do something that is not motion in order to keep the units of space ahead of the photons that want to hop through them.

The non-motion thing could be explained if a gravitational field were a sort of extra-dimensional conveyor belt

(continued)
dnatwork
1 / 5 (1) May 04, 2011
that forces units of space away from massive objects (they get crowded out as the local density goes up?) and into regions of space that are emptier.

At that point, the gravitational field might look like a surface from a distance (the stereotypical rubber sheet with a bowling ball in the middle), but that flatness is an artifact of the observer's perspective. Looking very close (and in an extra dimension), you'd see that there is volume and structure and motion within the plane of that sheet. Rotate your perspective, and the first sheet would leave your view while new ones constantly blossomed before you, but all of them are just Flatland representations of a higher-dimensional reality.

There's still a problem of motion here, though. The units of space should not exceed the speed of light even in that extra dimension, so how do they get away from the photons that are trying so desperately to hop on them?

(continued)

dnatwork
1 / 5 (1) May 04, 2011
I think that can be answered if photons are constrained a move a discrete unit of distance in a discrete unit of time, which sounds like a bit of quantum mechanics, as far as I understand it. Crucially, they cannot move less than that or more than that, nor any faster or slower. Now add this caveat: There must be a unit of space waiting to receive the photon in its destination, or it is forced to hop back to where it came from.

Now it is not necessary for the gravitational conveyor belt to move away from the photon faster than light. Instead, it just has to move TOWARD the oncoming photon fast enough to leave it no place to land.

In a normal gravitational field, the fractional motion of space-units is such that the photon can catch the next unit of space, or the one after that. Near a black hole, on the other hand the fractional motion of space-units is such that the photon always misses its mark. I think you'd stop seeing photons escape when the conveyor belt reaches c/2.

(cont.)
dnatwork
1 / 5 (1) May 04, 2011
At greater than c/2, the fractions are in the photon's favor again, and it eventually does hop to the next unit of space. However, its origin was also moving at greater than c/2, so it actually ends up going backwards (from the perspective of a distant observer, who of course never actually sees any of this).

No doubt it would be better/simpler to get rid of the conveyor belt in any real theory, and instead say something along the lines of the units of space being compressed or inflated depending on their location in the gravity well. But my original point was, this article led me down the path to the conveyor belt analogy, and suddenly I can visualize things in a way that helps me understand better (maybe, I think).

"Doesn't c include the concept of time, as it is a speed?" - Dnatwork

c can be a velocity. But with the appropriate choice of units in physics then c becomes a dimensionless constant = 1.



I don't have to be a physicist to recognize algebra. The only way to get rid of t in the denominator of your equations is to multiply everything else by t, or by something that includes t. Cheating!

Also:

Speed = d/t

Velocity = speed + direction = (d/t) + direction

Ergo, c contains t no matter how you slice it.

Don't split hairs, dude, you undermine your credibility.

dnatwork,
The thing about that rubber sheet analogy is; What is its topology, without the gravity wells? Flat. So we add the gravity wells and it's not flat anymore, but the areas between those gravity wells are not still on the original flat plane, but are pushed up proportional to the degree the wells pull it down, so the overall effect is still flat. That is exactly what we observe. Between gravity wells, there is this cosmological constant which balances the effect of gravity and keeps the universe from collapsing. Now if we observe light that has managed to weave its way past all the intervening gravity fields, it has only crossed space which is part of the "bulged out sheet" and so is redshifted relative to distance. If I may use another simplistic analogy, it has been climbing up the down escalator.

I didn't say "science." Science is the study of processes. Math is static because it is conceptual modeling and modeling is reductionistic framing. If you still have dynamic processes going on, within that model, it quickly breaks apart. Physics must describe the dynamic processes and it necessarily gets fuzzy when it gets too precise. Consider the concept of one. As math, it's eternal and inviolate, but consider any individual physical object and it's just a finite and subjective node in some larger network.

With that said... Reality is what it is, not what we think it is. We can observe reality and participate in it, but our definitions of reality do not necessarily prove the nature of reality. The best we can hope for is to observe and affirm reality. I believe reality continues whether or not I observe it, and if my observations change or add to reality, then I have more power than any one would give me credit for.

There is one question I do not see the answer to in this thread. That is hopefully simply put, If our universe ceased to exist would time still exist? If time is a function of movement, gravity, space, thought, observations, whatever... Does time exist without our Universe? Does time only exist because energy-matter exists? Or is time existent on some level without our participation?

No, better to keep the conveyor belt in the form of the lines of force of the gravitic field (like magnetic field lines, but with no poles). The force lines extend in all directions and follow an elliptic path, with the massive object as one of the foci. The stronger the gravity, the closer the approach of the ellipse to that focus, and the farther the other end reaches out into the rest of the universe.

If gravity is mediated by particles, they would zip along the force lines at a speed determined by the shape of the ellipse and their position on it. Really wide ellipses (black holes, of course) would have a point where the outward motion drops to zero, so the particles just hang there and never return their juice to the universe.

Just repeating yourself doesn't change things, indeed that seems the point of your idea. So how about you take your own concept to heart and CHANGE instead of repeating the same thing.

But change still takes time. Time may be meaningless without change but there is no change without time. Time is NOT just a numerical order of change. It CONTROLS how much change can occur in any interval. The length of time is the key not the amount of change.

As we observe and count its duration time can only be a measure of the change from moment to moment or from cause to effect, of the conditions or positions of space and matter.

Therefore, it cannot be considered as a directional dimension (e.g., 1-D, 2-D, 3-D, etc.) of empty space, electro-gravitational energy fields, or material forms.

This dos not mean that the universe is timeless, but that time is not a scalar dimension, nor is it a directional vector other than as a measurement of the rate of change from one physical or metaphysical condition or position to another. For example, frequency is the change in time of cyclic motion as an energy wave expands and contracts from positive to negative polarity.

Obviously, then, time cannot be the cause or effect of such change, nor is it any part of the wave or object that changes its shape, position, momentum, etc.

But this is incorrect, as spacetime controls the local perception of frequency.

If two observers are in uniform motion relative to an observed frequency generator (they're not in motion relative to the generator) and one is in a gravity well and the other not, they will perceive different frequencies from the same source (and experience different clock rates from each other, as a result). Therefore, time is a property of spacetime, and not simply a numerical order of change.

We use the (subset of understood) words in this dictionary not only to invent stories, we also use them to invent new words; therefore mathematics is richer than physics.

Well that is one way to put it. I don't myself. I think of it as more a matter of symmetry breaking.

While this is a very lyrical picture, I see things more pragmatic:
I see it as mathematical. Nothing lyrical in it. VERY pragmatic in any case. Just do the math.

The physical universe is the initial source for the words in a dictionary (called mathematics) made by humans.
The principles of math are not dependent on the Universe we live in. As you pointed out we a fully capable of coming up with math that is NOT dependent on our Universe.

therefore mathematics is richer than physics.
Yes. But not all forms of math are compatible with a functioning Universe. Some forms of math are not compatible with each other. Such as Euclidean vs. Non-Euclidean geometry.

Well it allows us to exist anyway. In THIS Universe.

We may create stories and call them "other universes" but they'll remain unfalsifiable human phantasies forever.
Not fantasies. Philosophies that can lead to new ideas and ways of thinking about things. They may even someday be testable. Kind of like string theory maybe being testable someday.

Maths and physics are not identical with their objects.

It has the sense of an ordered series, but that's just an illusion under the 4D block universe. In the block universe, with no time, nothing moves, nothing "happens", and literally nothing "changes". Why things appear ordered then becomes a HUGE mystery. There quite literally is no "becoming" under this view.

As you can see Amrit has a problem with 4D space. He can't make it go away in the math but he keeps making the claim that it doesn't exist.

What do you mean by 'BLOCK' universe? Please tell me it does not involve 'conveyor belts'.

In the block universe, with no time, nothing moves, nothing "happens"
Yes, BLOCK or not. So what does that have to do with a Universe with time? A ordered series of change IS time. Note that Amrit has admitted that this is mathematically indistinguishable from the usual concept of time. He seems to have forgotten he said that.

Why things appear ordered then becomes a HUGE mystery.
No more so than in the Standard Model where particles have no direction in time. One of the favored idea is that entropy gives direction to time on the macro level. I like that but I tend to go with it as property of the Universe and WHY doesn't enter into it.>>

What I wrote I am pretty darn sure matches the actual concept of the article. In the article time is an illusion due to an ordered series of change. Which Amrit has admitted is indistinguishable mathematically from time.

What you are saying is if there is if there is no time there is no change, which I agree with but that is NOT what the article is saying. Amrit is saying that the time is just a listing of change in an ordered series. But the two ways of thinking produce the same math. No matter how many PMs Amrit sends me saying I don't understand it. He has yet to show a single mistake in what I have written. Even in the PMs.

Hi Ethelred,

If the universe is 4d, and all events, past, present, and future, already exist in this 4d universe, then yes, there is no change. You apparently find this counterintuitive, as do I. However, to state that there are 4 dimensions that exist in a block universe as argued by the tenseless physicists entails that nothing ever changes. The future is what it is, and does not change - it's "there" already. In this sense, the article really is poorly written because it switches back and forth between the A theory and B theory of time.

Wouldn't you think that the burden would be on those upending one of the foundations of GR, i.e. space-time? I merely point to one famous mathematician's work, that IS consistent within GR that has yet to be proven incompatible with reality, AND that the authors of the paper in this article refer to.

Further, Godel universes aren't an ignored area of study. Many physicists have spent time studying Godel's solutions and, again AFAIK, nobody has come up with why a universe couldn't be constructed in this manner and still be consistent with GR. They have shown, however, that our universe seems to not be a Godel universe based on red shift observations.

No. To the extent GR matches observations, it's silly to talk about upending it. The problem comes in when a mathematical construct goes beyond observation and makes further claims, which almost all mathematical constructs do. Past the point of observation, it is precisely those claiming the additional "reality" to prove it. Part of any "improvement" to GR in the future might entail that CTCs are impossible.

Agreed. But, if time was a real "dimension" of space - why is it that we can move willfully in any direction, at any speed, and to any place in 3-D metric space, but cannot speed up, slow down, or change our position in time - no matter how hard we will it?

@Jnwaco: Lost me there. My point was that CTCs have been shown to be consistent with GR and seem to me to be in direct conflict with the article's premise. GR is a theory that has been validated time and again by our observations. As such, the idea that time is not what GR says it is give me pause.

I think CTCs are evidence that GR needs to be "improved" as you put it. I believe they are an artifact of a theory pushed beyond its limits, as are singularities in black holes and a myriad other "allowable" things within GR. Intuitively I like the author's premise, but without the math to fix GR, they just aren't saying anything novel or useful.
(btw, I don't think CTCs are affected by the idea of past present and future being predetermined. In fact I think CTCs would be very possible in "block time".)

I have absolutely no reason to doubt that they are currently mathematically consistent with GR. And I agree 100% that they hint at a need to improve upon GR and that it has been pushed past its limits - or ours.

The thing about that rubber sheet analogy is; What is its topology, without the gravity wells? Flat. So we add the gravity wells and it's not flat anymore, but the areas between those gravity wells are not still on the original flat plane, but are pushed up proportional to the degree the wells pull it down, so the overall effect is still flat. That is exactly what we observe. Between gravity wells, there is this cosmological constant which balances the effect of gravity and keeps the universe from collapsing.


If gravity causes both the well and the bulge, doesn't this imply that gravity is both attractive (near the mass) and repulsive (far from the mass)? If that's true, and if gravity were described that way in the theory (I assume it is not; the cosmological constant is a fudge factor that Einstein did not like, right?), why would one need dark energy? That is, would there be anything left for dark energy to explain?

I simply have seen no advantage whatsoever by avoiding using TIME and trying to replace it with change. Amrit has said nothing that gives us a clue as to why anyone would want to do so. At present the best thing I can come up with about time is that it is a property of the universe we live and the only why is that it makes for a viable functional universe.

A "static universe" is precisely what physicists who take Minkowski Space too literally end up proposing.

You seem to have confused my conveyor belt with someone else's block time.

If light is never slowed down, then why does is not escape a black hole? Is the idea that it is redshifted to an infinite wavelength, and somehow that explains why it can't get out? How is that different from being slowed down, really?

Or, it is still moving at c in its own frame of reference, and our perception of it from our frame is hindered?

The conveyor belt is really all those frames of reference moving in relation to one another, in a chain that is stretched or compressed by the gravitational field. They are just really small frames.

Indistinguishability. The electron. You are not suppose to be able to distinguish between any two given electrons.

There's a catch to that. As long as those two electrons are viewed separately and isolated, we hold to that claim. Otherwise not. Quantum states differ then.

Taking measure (of differences) smaller than Planck measure will inevitably lead to many discourses. You are witness to such a discourse. :)

QM and GTR bear many witnesses. Great thread to which I no longer participate. Seeing nothing new, call me shortsighted.

My best answer is to go poke around on physicsforums.com in the astrophysics area. But barring actually looking for the right answer, here I go.

Gravity bends light. Light actually striking a point on the event horizon is bent enough that it just goes in a circle and doesn't leave.

There! An answer that avoids all the tricky questions. Who cares if it is right or not?

@Pyle: So light is still zipping along at c, but the space it is in has bent so much it folds back on itself, or into some kind of hyper-donut, or whatever shape would explain the fact that the light does not progress any farther despite its speed.

Excuse me if I should have said velocity. I'm not the difference matters when space itself is warped.

Possibly. There is a lot of stuff going on in this thread.

If light is never slowed down, then why does is not escape a black hole?
Light always travels at C in a vacuum. It doesn't escape a Black Hole because there are no paths out of a Black Hole. Light always travels in a straight path in space-time, which is not the same as a straight path in space. With a Black Hole ALL paths are contained within the BH. Another was to look at it, an easier way, is that light is bent back into the BH.

Is the idea that it is redshifted to an infinite wavelength, and somehow that explains why it can't get out?
Only if you assume that it is possible to point the light PERFECTLY out from the BH AND the BH is not spinning. Even a path that seems perpendicular to the surface of the BH can't leave the BH. It will just still just go around in a circle. Exactly as would happen in our Universe if it was closed.>>
Ethelred
1 / 5 (1) May 13, 2011
How is that different from being slowed down, really?
That could only occur at the exact Event Horizon. Inside the BH there is no path out. At the EH that is what would happen. Only with a frequency of zero you don't have a photon anymore. So it wouldn't exist.

Or, it is still moving at c in its own frame of reference,
Light in a vacuum doesn't experience time. So I tend to think of it as not having a frame of reference. Now if we don't assume a perfect perpendicular THEN it would be moving at C in an orbit around the BH within the Event Horizon. Again if it started within the BH there is no path out.

And I may be completely full of shit on what happens at the Event Horizon. Inside I am pretty sure about. Outside isn't a problem. At the exact EH I suspect that questions about existence become kind of meaningless since time is at a standstill. Which I suppose means you can't produce a photon there to worry about.

Time "stopping" at the EH is an illusion because as you get closer and closer to the EH, light has a harder and harder time escaping the gravity. To an observer, it may appear as if you never enter the EH. You merely cross the EH and keep going, implying that time does not stop for you. Eventually, however, you're crushed to death, though.
dnatwork

So, light doesn't slow down, but its path is diverted, so it never gets where it seemed to be pointed when it started out. Or another way, its speed does not change, but its direction (and therefore its velocity) does.

For me, that's why the conveyor belt analogy helps. If you go in any direction, there is a specific path you must follow, defined by Planck-sized units of space linked together in a chain. That chain loops back on itself eventually; near a black hole, it loops back before you get out.

I guess I would think of the event horizon as the interface between convection cells, only infinitely thin. It's basically the imaginary space between the real spaces where things happen, so nothing can happen there because nothing can exist. A border that is a human construct, an artifact of theory that we have named for our convenience.

In quantum vacuum time is the numerical order of material change. In quantum vacuum past, present and future exist only as a numerical order of change. Numerical order on its own has no duration. Duration of numerical order of change enters existence by being measured with clocks by the observer. The observer's measuring creates "time" in a common meaning of this word.

I seriously doubt this and you have presented NO evidence to support it. As others have pointed out this has a frozen chicken in time stasis which is silly. Far more likely is that the minimum time interval is the Planck Interval and that change is constrained by that interval. Light cannot travel farther through space-time than the Planck Length.

"BACK YOURSELF UP. Deal with General Relativity. Tell us why we should replace time with change, what we gain from it. Evasion of this shows you as a Crank and not a scientist."

At the same time, general relativity is constantly being interpreted beyond what observation would indicate (and in the case of consciousness, in direct contradiction to what we experience).

We do not experience ourselves as a 4D "worm" that has components in multiple time dimensions. We have no knowledge of the future, and the past is a fading memory.

That's why I'm still befuddled at the notions of this article and the title. If we remove time as a dimension, it explains a lot. General relativity is still valid and Makoski spacetime is still a convenient, accurate method of doing the calculations. But to take that too literally, beyond what we consciously experience (observe) has literally no scientific justification.

Obviously we experience the passage of time. We experience being in terms

In quantum vacuum, time we measure with clocks is the numerical order of material change. In quantum vacuum the "past", the "present" and the "future" exist as a numerical order of change only. A numerical order has no duration of its own. A duration of a numerical order of change comes into existence through being measured with clocks by the observer. The observer's act of measuring creates time as duration of material change.

I understand what they mean by there is no time or all the time is the same. A second is actually referred to as a clock tick from one point to another. So you are actually measuring the angular motion of the second hand with respect to any other object that moves. But I am a bit confused when it comes to periodic motion. Say something moves periodically, the word 'periodically' needs sense of time here. Take an electromagnetic wave with constant frequency, so time here is really interpreted as constant displacement+propagation for every oscillation with respect to constant displacement+propagation of another object (clock second hand) for every revolution(tick). So all-in-all time is completely relative and apparent, not physically measurable but a sensibly measurable quantity.

That is the problem with the article. It trys to replace TIME with CHANGE and makes no effort whatsoever to fix the mess that would make in physics. Thus it adds nothing of value to physics.

Ya, the clock ticking IS a physical instrument, but as per the article, what you measure is _exactly_ _not_ time but the change in movements of the hands with respect to something else that gives the perception of time.

This makes me think even mass is not measured directly/correctly. In a balance we measure weight which is mass times gravity. What if the gravity is not same as on the both sides of the pans? As it is proved gravity is not same in every point on earth(from my 6th std physics book).

I think for certain class of physics time need not be considered as a dimension or consciousness of dimensions are not reqd, so this will never affect those. It will be gr8 If they can only give a easily understandable way for their article and a 6th std student can understand and solve his textbook problem.

I had this question from when I was a kid, Why unit of time is measured in an absurd way (100ms=1s, 60s=1m, 60m=1h, 24h=1d, 365.25d=1y)? Is there a base 10 system for time?

The 'respect to something else' is just a circumlocution to avoid using the word TIME. And since the hands can move MORE or LESS in the same amount of TIME its a VERY bad concept. This is why someone brought up the frozen chicken. Change is measured relative to time because it WORKS and the opposite will just produce a big mess.

In a balance we measure weight which is mass times gravity.
No. We measure MASS in a balance. A spring scale measures weight. Increase gravity and a spring scale changes, a balance doesn't.

What if the gravity is not same as on the both sides of the pans?
Then its a lousy measurement which will change if you move the device.>>

That is over a large area. Unless you happen to have some exotic matter handy. Or a REALLY big balance.

I think for certain class of physics time need not be considered as a dimension
I think there was an example or two on the thread. Also some attempts to HIDE time while hoping that no one would notice the trick. For instance a balance is dependent on time as it take time to put the weights on and time for the movement to damp out.

Why unit of time is measured in an absurd way (100ms=1s, 60s=1m, 60m=1h, 24h=1d, 365.25d=1y)?
Because the Babylonians used multiple bases and Earth based time units. Base twelve, ten, and 360 and maybe I missed a couple. The key base was twelve. Then later shorter intervals were added in using base 10.>>

We still use dozen and gross today. Dozen has some advantages. It is divisible by 1, 2, 3, 4, and 6 vs. 1, 2, and 5 which makes it easier to split up a dozen evenly then with ten.

However to get back to the article. You have only touched on part of the idea. The other was that time is a numerically ordered measure of change and not a physical measurement. Which is silly. It can be considered as a numerical series but it is time that constrains the amount of change and not the other way around and Amrit is unwilling to deal with that reality. That is why any attempt to replace TIME with CHANGE is doomed to look as stupid as digging a hole in water.

60s=m, 60m=1h, 24h=1day for the same fundamental reason that eggs are traditionally sold by the dozen and the imperial measurement system was based largely on 12 and 16.

Look, the fact is that for the time being (no pun intended) no one, including Amrit, knows what time OR space is on a fundamental level. Are they quantized or infinitely divisible? Open question. Are they fundamental or emergent? Open question. The dimensions of space and time can both be considered as degrees of freedom of position (and in the case of space, orientation). Time is more restrictive. Only movement in one "direction" is allowed. Why? Open question. What if one of the "space" dimensions had a similar directional restriction? Perhaps we would then "experience" 2Ds of space and 2Ds of time. Open question. Maybe in that sense time is no more than a broken space dimension.

Change is measured relative to time because it WORKS and the opposite will just produce a big mess.
I guess current system of time helps us to understand stuff easily(relative). Someone has to re-explain for this system.

No. We measure MASS in a balance.

I thought a balance, balances the forces on the pans and the pointer moves due to the resultant torque.

Then its a lousy measurement which will change if you move the device.

gravity cannot change suddenly from one point to another. It must vary gradually :S. So technically you are measuring forces due to different gravities.

See currently we think time as

At 0 sec the body is at 0, at 1 sec it is at 5, at 2 sec the body is at 10, etc.

I think what they mean by time as a change of state

The body is at some point, lets say that as 0s,
the body is at 5m, lets call that 1s,
the body is at 10m, lets call that 2s, etc,

Now qn comes how you give 1s for 5m? answer is using a clock, where each tick(movement) is mapped to something that moves or something thats at rest apparently(the observer)

...people, especially philos and physicists, a lot more than space does, even though they both present the same fundamental ontological problem. Amrit seems to be REALLY uncomfortable with the nature of time (or rather not knowing its fundamentals) to the point where he is trying to do a lot of hand waving to make it just go away. His case is so bad that it's come to the point where we're, well, just having some good natured fun with the fellow. Fact is, even the current champion of the Time-does-not-exist camp (I know, technically this is not supposed to be Amrits position, but close enough), Julian Barbour can't make Time really disappear; he just recasts it as a one way space dimension. But then, if it's really just a special one way space dimension, well, isn't that just...Time? Anyway, I do find it interesting to think about, but in the end, as Eth writes, if their efforts are just a matter of recasting time as an equivalent with different semantics, that doesn't help physics.

Hard times ;) Now time seems to be kind of a mapping to me. :P The easiest way to understand what the article is about is to

1. Think you are learning physics
2. Strike the line in your physics book that says Time is a physical qty' and replace it with 'Time is a sensibly measurable qty'
3. Think of problems where you map time with some state, and where time seems to drive the motion. Now replace that thought with motion being independent and time being attributes given to different states.
4. Now solve them. There is no difference(mathematically) in both the methods, only logically you assume time is some name given to a certain state.

Its kind of works like a primary_key<->foreign_key in a database. I find it easy to understand by relating it to database, as I am a developer working on the backend.

True, Pi, e, & roots aren't any easier, but you do get more even divisors. It's really handy to be able to split quantities cleanly into halves, thirds and quarters, and to be able to divide those again into halves and thirds. Can't do that with 10. That's all I meant by being a little easier.

Also, while your objection is quite correct as far as doing base 12 math using only 10 base symbols, if you add 2 extra unique symbols to base ten to make it base 12 (0, $, &, 1, 2, 3, 4, 5, 6, 7, 8, 9, $0, $1...) then drill multiplication tables into your head like you did with base ten, then adding, subtracting, multiplying, and dividing are no harder or easier, IMO.

Not in 1000 characters. Forget it. Look up fine structure and hyperfine structure on the Wiki (it's fine). Basically, when a caesium-133 atom goes from one hyperfine state to the other it emmits a photon. Count 9,192,631,770 oscillations of that photon and that's one second. One reason to use such a method is that it's based on a physical constant. It's not an invented standard like XML. And there are reasons for the latter too. If you don't like programming standards, move back to the 80's! If you don't like physical constants, than move to a universe with fundamental random variables! Of course you might not have an easier time hacking reality in one of those. Still you may have over 10^498 of them to choose from.
