(Phys.org) -- Philosophers have debated the nature of time long before Einstein and modern physics. But in the 106 years since Einstein, the prevailing view in physics has been that time serves as the fourth dimension of space, an arena represented mathematically as 4D Minkowski spacetime. However, some scientists, including Amrit Sorli and Davide Fiscaletti, founders of the Space Life Institute in Slovenia, argue that time exists completely independent from space. In a new study, Sorli and Fiscaletti have shown that two phenomena of special relativity - time dilation and length contraction - can be better described within the framework of a 3D space with time as the quantity used to measure change (i.e., photon motion) in this space.
The scientists have published their article in a recent issue of Physics Essays. The work builds on their previous articles, in which they have investigated the definition of time as a “numerical order of material change.”
The main concepts of special relativity - that the speed of light is the same in all inertial reference frames, and that there is no absolute reference frame - are traditionally formulated within the framework of Minkowski spacetime. In this framework, the three spatial dimensions are intuitively visualized, while the time dimension is mathematically represented by an imaginary coordinate, and cannot be visualized in a concrete way.
In their paper, Sorli and Fiscaletti argue that, while the concepts of special relativity are sound, the introduction of 4D Minkowski spacetime has created a century-long misunderstanding of time as the fourth dimension of space that lacks any experimental support. They argue that well-known time dilation experiments, such as those demonstrating that clocks do in fact run slower in high-speed airplanes than at rest, support special relativity and time dilation but not necessarily Minkowski spacetime or length contraction. According to the conventional view, clocks run slower at high speeds due to the nature of Minkowski spacetime itself as a result of both time dilation and length contraction. But Sorli and Fiscaletti argue that the slow clocks can better be described by the relative velocity between the two reference frames, which the clocks measure, not which the clocks are a part of. In this view, space and time are two separate entities.
“With clocks we measure the numerical order of motion in 3D space,” Sorli told Phys.org. “Time is 'separated' from space in a sense that time is not a fourth dimension of space. Instead, time as a numerical order of change exists in a 3D space. Our model on space and time is founded on measurement and corresponds better to physical reality.”
To illustrate the difference between the two views of time, Sorli and Fiscaletti consider an experiment involving two light clocks. Each clock's ticking mechanism consists of a photon being reflected back and forth between two mirrors, so that a photon's path from one mirror to the other represents one tick of the clock. The clocks are arranged perpendicular to each other on a platform, with clock A oriented horizontally and clock B vertically. When the platform is moved horizontally at a high speed, then according to the length contraction phenomenon in 4D spacetime, clock A should shrink so that its photon has a shorter path to travel, causing it to tick faster than clock B.
But Sorli and Fiscaletti argue that the length contraction of clock A and subsequent difference in the ticking rates of clocks A and B do not agree with special relativity, which postulates that the speed of light is constant in all inertial reference frames. They say that, keeping the photon speed the same for both clocks, both clocks should tick at the same rate with no length contraction for clock A. They mathematically demonstrate how to resolve the problem in this way by replacing Minkowski 4D spacetime with a 3D space involving Galilean transformations for three spatial coordinates X, Y, and Z, and a mathematical equation (Selleri's formalism) for the transformation of the velocity of material change, which is completely independent of the spatial coordinates.
Sorli explained that this idea that both photon clocks tick at the same rate is not at odds with the experiments with flying clocks and other tests that have measured time dilation. This difference, he says, is due to a difference between photon clocks and atom-based clocks.
“The rate of photon clocks in faster inertial systems will not slow down with regard to the photon clocks in a rest inertial system because the speed of light is constant in all inertial systems,” he said. “The rate of atom clocks will slow down because the 'relativity' of physical phenomena starts at the scale of pi mesons.”
He also explained that, without length contraction, time dilation exists but in a different way than usually thought.
“Time dilatation exists not in the sense that time as a fourth dimension of space dilates and as a result the clock rate is slower,” he explained. “Time dilatation simply means that, in a faster inertial system, the velocity of change slows down and this is valid for all observers. GPS confirms that clocks in orbit stations have different rates from the clocks on the surface of the planet, and this difference is valid for observers that are on the orbit station and on the surface of the planet. So interpreted, 'time dilatation' does not require 'length contraction,' which as we show in our paper leads to a contradiction by the light clocks differently positioned in a moving inertial system.”
He added that the alternative definition of time also agrees with the notion of time held by the mathematician and philosopher Kurt Gödel.
“The definition of time as a numerical order of change in space is replacing the 106-year-old concept of time as a physical dimension in which change runs,” Sorli said. “We consider time being only a mathematical quantity of change that we measure with clocks. This is in accord with a Gödel view of time. By 1949, Gödel had produced a remarkable proof: 'In any universe described by the theory of relativity, time cannot exist.' Our research confirms Gödel's vision: time is not a physical dimension of space through which one could travel into the past or future.”
In the future, Sorli and Fiscaletti plan to investigate how this view of time fits with the broader surroundings. They note that other researchers have investigated abolishing the idea of spacetime in favor of separate space and time entities, but often suggest that this perspective is best formulated within the framework of an ether, a physical medium permeating all of space. In contrast, Sorli and Fiscaletti think that the idea can be better modeled within the framework of a 3D quantum vacuum. Rather than viewing space as a medium that carries light, light's propagation is governed by the electromagnetic properties (the permeability and permittivity) of the quantum vacuum.
“We are developing a mathematical model where gravity is a result of the diminished energy density of a 3D quantum vacuum caused by the presence of a given stellar object or material body,” Sorli said. “Inertial mass and gravitational mass have the same origin: diminished energy density of a quantum vacuum. This model gives exact calculations for the Mercury perihelion precession as calculations of the general theory of relativity.”

Higher energy density = gravitational self energy (General Relativity) = more virtual particles (QM) = more scattering events per unit volume (QM) = lower light speed (QM) = more space (interpreted c = constant).

1.7 / 5 (29) Apr 14, 2012This isn't quite right. Length contraction, a component of SR, must occur because both clocks tick at the same rate. Clock A must 'catch up to' the receding mirror in direction of travel, so without length contraction clock A would tick slower than clock B.

Gödel said in his solution of Einsteins field equations of gravitation:
"...But there also exist closed time-like lines....; i.e., it is theoretically possible in these worlds to travel into the past, or otherwise influence the past."
which would imply closed causal loops or branching.

1.7 / 5 (31) Apr 14, 2012Wrong. That is in fact why the moving photon clocks WILL slow down. From the perspective of an observer not with the moving clocks, clock B takes a saw tooth path through space, so its light travels a longer distance than that observed from one riding along with clock B. From the observers perspective moving with the clock, he is at rest.
Noumenon
1.6 / 5 (28) Apr 14, 2012There is no contradiction at all. A velocity vector of the clocks only comes about because of the perspective of an observer, not moving with the clocks. This velocity vector direction has an effect on the path taken by the light, from the perspective of an observer not moving with the clocks.
No one said "time dilatation requires length contraction". If you only had clock B, you would not require length contraction, but there would still be time dilation. Length contraction comes about due to the non-moving observers determination of reletive direction and orientation of the clocks.

This is analogous to how the component velocity in the north direction is reduced by traveling some in the east direction.

That "energy density" is the "dark energy" they have used to patch current theory to match observations. And gravity is also the same force, pushing from everywhere. The pull comes from diminished gravity, not from some circular reasoning "gravity well".
And if we could make a nano-material transparent to this force from one direction, we´d have free energy and could travel to the stars.

1.1 / 5 (8) Apr 15, 2012Such a definition of time is apparently qualitative only and for the quantification of time you would need to express the FREQUENCY of changes, which is what the old definition of time would be very useful. After all, nobody prohibits anyone to define time accordingly to suit particular needs, the radiative time arrow used in relativity is only one of many definitions of time...
The charge of magnetic field intensity are sorta abstract concepts only. For example, what else the space is, than the time required for light to travel between different places of it? The bats are using such a definition of space, because they're navigating with longitudinal waves, not transverse ones.

2.8 / 5 (5) Apr 15, 2012Subjective experience of time is a mental illusion. At the quantum level, only entanglements caused by forces can produce change. Without change there is no time. Since the distance formula is always positive, there is no possibility of time travel.
We don't live in 4D Minkowski space. We live in nD (presumably 10D) space with virtual time (or derivative time). Even Kaluza-Klein knew this to be true.

But what then of the quantum vacuum - isn't it supposed to 'fizz' through time, or would this field cease to have relevence in the absence of thermodynamic activity?
I must say i'm more drawn to the idea of time as external to what we think of as our universe, a more fundamental substrate common to all universes, in an M-theory kinda way... and ditto the vacuum...

So, I don't so much vanquish the idea of "time" completely from the equation, as view it from a more utilitarian perspective. IMHO, Sorli and Fiscaletti are no different than others who believe in the palpable existence of time, i.e. they begin their hypothesis with a false assumption, and therefore it is incorrect.

The speed at which new Ut space is being created just so happens to be approx 300,000kms. It is also responsible for the association and dissociation of atomic standard model interactive cohesion. The book published via Amazon books called Absolute Relativity - theory of everything explains all this. Explained in a very easy to read text with illustrations. The real dimensions are ut,x,y,z. Ut is the Primary dimension into which can exist Euclids x,y,z. It has an orthogonal expanding velocity with a time symmetry of '0'.

In this sense, time is simply a relation between events and not a fundamental existent entity. Nature herself does not care about such a comparison,... that is to say there is no discoverable "time particle". Time is Applied in relating things, not Discovered. The same goes for space (and possibly causality.)
We add the conceptual structure to support of knowledge of phenomenal reality. The lesson of qm was to not confuse the two, and presume that Reality, as it is unconceptualized, still abides by our a-priori intuitions.

For those who don't understand the significance, gravitational waves can be crudely described as "ripples of time". For time alone to carry away energy implies it has some physical reality.

Gravitational wave recoil is quite a recent discovery in black hole merger simulations and will be very difficult to confirm, but for any wave/particle moving at the speed of light, the momentum is equal to the energy so would be expected.

1 / 5 (4) Apr 16, 2012Just because an atomic clock operates faster at a higher altitude does not mean that it is because of time. It could have something to do with gravitation, for example. Or, considering the small amounts of difference we could have measurement errors.
Then there is this idea proposed in some book somewhere, that if you move away from a wall clock at the speed of light, you could (in a thought experiment) see the photons from the clock (which would show you the same time continually) and that this would "prove" that "time stands still" when you move at the speed of light.
The problem with this idea is, however, that time does NOT stand still when you move at the speed of light. How do we know this? Because it would still take you 1 whole year to move the distance of a light year. If time actually stood still you would traverse that 1 light year distance instantly.

2.4 / 5 (8) Apr 16, 2012The reason they didn't work with the degree of precision we expect today is because they were circular and not elliptical. For 2000 years ago, it was still pretty good math. One could presumably create a mathematically precise geocentric model of the universe, for the very obvious reason that we exist in one and math does attempt to model reality. It would just be more complicated than other descriptions and what resolves the best choice among competing models is Ockham's Razor; What is the most efficient model that explains all that is necessary. Relativity does offer an effective model, but it does raise some unexplained issues and doesn't resolve some others. We don't know whether a simpler and more effective model will come along to replace it, before it does. The future doesn't advertise.

What observation tells us is that clocks on Earth and in the spaceship behave like odometers and the difference in their readings at C can be predicted using Pythagoras.
Now you could claim that odometers should really measure change of latitude but travelling east-west makes them inaccurate but few people would consider that credible. I don't see why we should take that approach with clocks but that is what Sorli and Fiscaletti are proposing.

1 / 5 (2) Apr 16, 2012No. Augustine of Hippo argued that it was impious to consider that God could be omnipotent yet at any time have nothing over which to rule hence it was near blasphemous to imagine that time could have existed before he created the Earth etc.. The only way Augustine could reconcile that was to say time couldn't exist before matter, hence time must only be a description of the motion of created items. That is the philosophy Sorli et al are trying to reintroduce, they are saying it is not a measurement but an invention of our minds.
To do so (judging only from the above review), they apparently deny the result of numerous experiments (such as Michelson Morley as has been mentioned) and pretend the results were something other than they actually are.

3.7 / 5 (3) Apr 16, 2012I'm afraid not. To work like an odometer, space and time must be similar in nature so that Pythagoras applies. If there is only space as they suggest, clocks could only measure in one way, like an instrument in a car registering latitude instead of mileage.
Odometers, altimeters and clocks are all instruments that measure something, we are not arguing about that. Note what they say:
"The rate of photon clocks in faster inertial systems will not slow down with regard to the photon clocks in a rest inertial system because the speed of light is constant in all inertial systems, the rate of atom clocks will slow down because the 'relativity' of physical phenomena starts at the scale of pi mesons."
In other words thay say a photon clock should work like an altimeter while an atom clock should work like an odometer. The reality is that they both behave identically. The M&M experiment is a 'photon clock'.

1 / 5 (2) Apr 16, 2012Aether theory says that light is a wave in the substance. As I have told you several times before, and you would have known if you had studied aether theory, since light is polarised, it must be a transverse wave hence requires shear strength and a gas has none.

1 / 5 (8) Apr 16, 2012I didn't say it is. The dense aether model is more general and it doesn't attribute any particular outer geometry to the Universe. Nevertheless, the dispersion of light with vacuum fluctuations will lead to the FLRW metric, which corresponds the black hole inside out. FLRW metric is the basis of standard cosmology.

Photons are solitons (wavepackets) of transverse and longitudinal waves in similar way, like the Russel's solitons at the water surface. If the light would be formed with pure harmonic waves, then the photons could be never formed in it. Do you see, how little do you understand the light?
Turritopsis
1 / 5 (6) Apr 16, 2012So when you speak of photons, they are longitudinal flow. When you speak of light waves you're speaking of transverse motion. But light is actually both in every moment. So light is both longitudinal and transverse wave simultaneously.

1.6 / 5 (8) Apr 16, 2012I've spoken with an astrophysicist who would disagree.
Did you know a "black hole" does not have to have anything at the center? The shared center of mass of a system of densely packed stars could be the center of a black hole, in empty space. The density of such a cluster of massive stars could satisfy the conditions necessary of a black hole who's schwarzschild radius would fully encompass the cluster of stars, yet their shared center of gravity would fall in empty space. Everything entering the schwarzschild radius of such a system would "fall" into the system, possibly forming stable orbits around one of the component stars. Nothing has to be "spaghettified" at all.

1.2 / 5 (6) Apr 16, 2012Time is a measure of change, but what is space is a measure of? Distance, area and volume are measures of space, but it would seem space is what is being measured, not the measure of something more fundamental.
Time, on the other hand, is a measure of something more fundamental; Change. And change is an effect of action. Temperature is another measure, scalar, of action. We could use ideal gas laws to argue temperature is another parameter of volume, just as we use the speed of light to correlate distance and duration to say "space" and time are interchangeable, so why is there no "temperaturespace?" Given that space is considered to be filled with quantum fluctuations, which presumes some form of temperature, it would seem as foundational as "spacetime."
We know temperature is a measure and don't treat it as some foundational geometry, like we do with time.

IMO time is a RESULT of change (any change). Without change time is not "needed". Even a quantum event "requires" and creates time.

Which has no meaning in terms of actually doing science. Even if he was right there is not a single change in the way science would actually be done. No equation would change unless to make it make more awkward and everything would still be time-like and not change like.

All attempts to replace time with change, and Amrit tried doing that in posts here, turned out to have a timelike nature. Even when he tried to hide it by using an equation that had a variable that was timelike but he just intentionally left out what the variables actually stood for. In other words he tried to run a bluff and hoped that no would check what the variables really were.

5 / 5 (3) Apr 17, 2012Hi D_C, I'd be really curious to know what astrophysicist you spoke to about this, becasue, although the scenario you describe is not completely excluded, it would be rather temporary as once inside an EH the direction "out" is equivalent to going back in time. In other words, there are no stable orbits inside an EH and all bodies eventually collapse to the centre to form a Kerr BH. This is actually not unlike a stellar collapse after infalling matter has become dense enough to form an EH, but before it has formed a ring singularity. Your scenario is just more prolonged.
BTW, AA's point still stands. The pre-Big Bang singularity vanishes at the BB.

1.5 / 5 (6) Apr 17, 2012The universe has many properties, from quantum fluctuation to people. The issue is order of emergence.

5 / 5 (2) Apr 17, 2012Well, that's what I said :)
Sorry, this is tough at 1K charaters a pop. Also, I'm assuming a certain knowlege of BH, esp. Kerr BH (ergosphere & all). What I'm getting at is that even "orbiting" at C just outside the EH you'll still spiral in, inside even moreso. So the scenario you describe is very temporary, and "spagettification" inevitable...unless you can somehow go through the ring. You'd have to have V=C perpendicular to the EH at the EH not to fall in.
The same entity as outside the EH, but it behaves differently, i.e., space-like with the future being "down".
Deathclock
1.5 / 5 (8) Apr 17, 2012No... I'm not talking about orbiting outside of anything. External to the system the combined pull of all of the massive stars is enough to form a black hole at the point in empty space that is the combined center of gravity of those stars... INSIDE the system the stars no longer pull you to that center of mass when some stars are in front of you, some behind you, some to the left and some to right some up and some down etc... Then there is no "pull" toward the center, and you can form a stable orbit around one of these stars.
You don't understand I am not talking about a black hole formed by the collapse of a star, I am talking about a black hole centered on a combined center of gravity of many massive stars that pull toward that point ONLY when you are outside the system.
Deathclock
1.5 / 5 (8) Apr 17, 2012The attraction of the cluster of stars toward their center of mass could be so great that once inside the system nothing could ever escape it, because as you move toward the edge they ALL pull you back
Do you understand now?
Deathclock
1.5 / 5 (8) Apr 17, 2012Our universe could be the inside of a black hole (as observed from an external perspective). Inside the universe you have mass all around you pulling you in every direction and mostly cancelling out, but as you approach the edge of the universe all of the mass is behind you, pulling you in one single direction (toward the combined center of mass of the universe).

5 / 5 (3) Apr 17, 2012In Fatio's model, the Sun shields us from particles orginating on the far side from us, you understand that. If particles were reflected, some that come from our side of the Sun would reflect off it and bounce back to us. If you sum over the whole sky, the result is that those reflected exactly cancel the shielding hence there is no resulting force.
It's a primitive belief called "adding up" and even Le Sage knew that result. That's why he spent many years trying to solve the heating problem (but he never did).
Fleetfoot
5 / 5 (3) Apr 17, 2012No, your not good at logic because the waves are reflected on the outside so no heating but there are no waves (or at least fewer modes) on the inside hence also no heating. Reflected waves do cause a push as in solar sails. See my other post for why Fatio's model fails even though reflection would solve the heating problem, it creates a different one.
Russkiycremepuff
2.2 / 5 (13) Apr 17, 2012As to BH, EH can only be created outside of a BH. Although matter-energy cannot escape even from the outer edges of the EH, time, even as a dimension is not a factor in the inability of escape from the singularity and its EH even at the velocity of c. The EH is not a flat disk as portrayed in BH illustrations that look similar to the rings of Saturn, imo. We only think of it as a disk since that is most familiar to us, e.g., the early solar system; rings of the planets; subatomic particles. I tend more to believe that the EH is an outer "shield" that encompasses the BH, similar to the shell that encases a walnut or filbert but is penetrable and porous.
Deathclock
1 / 5 (4) Apr 17, 2012The event horizon is simply the distance from the center of mass of the system that, once traversed, light cannot escape back beyond that distance...
Most of what you said appears to be nonsense, but there may be a language barrier.
Russkiycremepuff
2 / 5 (8) Apr 17, 2012Time has no involvement in piece of matter-energy falling into a singularity through the EH first. If we are able to see the matter-energy falling into it, it may appear to slow down due to our distance from that event and how we conceive its physicality. The light that comes to us and our telescope has been long in arriving to our eyes and the singularity may have already moved even farther away and that whole region of space may no longer be there, having been consumed already.
We humans are prone to time constraints or the concept of that which we choose to regard as time, due to our abstract thought processes in our conscious moments.
But consider how we are in our sleep. In our unconsciousness during sleep, we are able to dream, but we have no concept of time passing. In those hours, we are no longer slaves to clocks, but when we wake up, time resumes for us due to our concept of it resuming.
Gawad
5 / 5 (2) Apr 17, 2012I understood you perfectly from the start, but I also know you're missing a very important point here:
If the mass of your combined system is enough to create an event horizon, it doesn't matter what the orbital speed of your objects is (whether stars, neutron stars or even independent black holes) inside the EH (and as I wrote, this also applies just outside the BH) the collapse of your system is INEVITABLE. No orbital speed can keep them apart. If they can orbit stably, you don't have an EH. Now, do YOU understand?
And while I concede you could sit in the *middle* of it in flat space-time until it all comes down on you and not have to worry about spagettification in that case...it would be the least of your worries!
So back to my original question: who was the astrophysicist you spoke, or what was his or her specialty? A lot of them specialize in analysis of atomic spectra and not necessarily in GR and exotic bodies. (Please, no Lisa Randall jokes, ok
Deathclock
2.4 / 5 (10) Apr 17, 2012What are you talking about? This is derived from mathematics... The event horizon is the point of no return, there is nothing to "see", it is not a physical thing, it is a distance from the center of gravity beyond which you cannot return, it is the point of no return.
It's not a real thing to discover, it's a thing that WE define.

4 / 5 (4) Apr 17, 2012Actually it isn't difficult at all, the two beams in their diagram are exactly what Michelson and Morley did over a century ago. If they say photons aren't affected but matter is, there should be a fringe shift in the MMX and of course there isn't.
Deathclock
1.5 / 5 (8) Apr 17, 2012The rate of collapse would depend on the size of the cluster, while I agree that the collapse to the center of mass is inevitable (barring such things as dark energy) it could well play out over billions of years, plenty long for a planet to form with intelligent life pondering such things.
Gawad
5 / 5 (3) Apr 17, 2012Actually, yes, correct, but only until the ultimate collapse of your system (or until the approach of another body in the system destabilizes it's orbit during the collapse)
It's more complicated than that, Deathclock. The space-time gradient keeps INCREASING as you move towards the mass(es) that contribute to forming the EH (in your scenario or any other). By the time an EH has formed, S-T is already so warped that even a photon can't climb directly out of the gravity well. And there's no way orbiting bodies can keep from ultimately heading for each other: they would need to orbit at a V>C. I don't know what astrophysicist you spoke to, but their specialty was't GR.
Fleetfoot
5 / 5 (3) Apr 17, 2012A black hole isn't a point, it's a region centred on a point. For the simplest non-rotating, uncharged region, the event horizon is the place where you have to travel at the speed of light through space just to stay at a constant radius.
In that case you have a globular cluster, not a black hole. To stay in a circular orbit 50% OUTSIDE the event horizon an object has to be moving at the speed of light, any closer and it spirals in so the stars can't exist inside for any significant time.

I.e., the parallel bewteen a universe that ultimately collapses and massive content spiralling together to form a black hole has often been made...not unfairly...but there does remain one serious objection: the ultimate fate of our own universe doesn't appear to be collapse, but heat death. So the idea of our universe being equivalent to a black hole that will ultimately reform it's original singularity from the (gravitational) collapse of its contents doesn't actually seem to hold.

Everything that fell in before you is already way ahead of you (you aren't going to overtake anything in a black hole). So the pull to the center will always remain - UNLESS another black hole fell in with you. To be more precise: The only way that gravitational pull is going to be non infinite for you in one direction very quickly is like this:
When you are right at the point where the event horizons of two approaching black holes of equal mass and zero rotation meet with a motion vector which is balanced precisely between that of the two black holes.
Fleetfoot
5 / 5 (4) Apr 17, 2012No, you're not getting it, if the density becomes high enough, there are no stable orbits so the motion of every star within the cluster becomes a spiral ending at the centre in a very short time. During that infall, adjacent stars would appear blue-shifted because they are all heading towards a common point.

A massless spin-2 particle is a graviton.

It's not that the forces go away, the vectors along which they pull you change as you approach or recede from the system.

Can you explain how this perception of change exists, if time is a static dimension?
On the other hand, applying Ockham's Razor, it could simply be a universe of energy and the changing configurations coalesce out of potential and are replaced, thus it is the events going future to past, not this present moving/existing along an external vector.

Consider the most elemental theoretical states; moments after the singularity, vacuum fluctuation, absolute zero. They are all most defined in terms of levels of activity, not rates of change. The problem is that we understand temperature is a measure, but since we perceive time as narrative from past to future, rather than the more elemental changing configuration, that process of change becomes the measurement of duration. If the change happens faster the duration is shorter and time is faster. All this still happens within the context of the present, not external to it. We are not moving into the future, it is the events receding into the past.

2.3 / 5 (15) Apr 18, 2012If 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, as the spacetime between the observers and the frequency generator is the only difference.

5 / 5 (1) Apr 18, 2012That's what I was saying. To counter the gravitational pull you need an equally stron force (i.e. something that is as massive and as close as the one pulling you in the one direction or vastly more massive if it is further away.)
To feel no acceleration (like we do) you'd need to have these two forces cancel out. Within a black hole the gravitational differentials are so great that along the diameter of the Earth you'd feel a marked difference in pull. [cont]
antialias_physorg
5 / 5 (1) Apr 18, 2012Gravity goes with distance squared. So no configuration of external masses (save for a lopsided Dyson sphere with one end being a black hole of universe mass itself - which BTW would already preclude it from being a Dyson sphere) would give us the feeling of not expriencing any net gravitational force like we currently do.
Even if such a stupendously unlikley configuration were to be true - it would only work for a miniscule central region. Assuming it is so finely balanced as to 'protect' the Earth then anything even marginally outside the position of Earth (like the Moon, any other planet or the Sun...not to speak of other stars/galaxies) would feel the full differential. We'd see spaghettification of all other objects. Instantly.

4.2 / 5 (5) Apr 18, 2012OK so since you decided to post I am going to ask that question you refused to deal with the last yet again.
What does science gain by using change instead of time? Keeping in mind that the mathematical circumlocutions you would have to use are exceeding awkward and tell us nothing new about the Universe.
IF a new theory is to replace a previous one it MUST
Give at least as a good a prediction of what will happen in experiments.
If it isn't a BETTER prediction then it must have something else going for it. It must either tell us something new the Universe or it must at least be simpler.
So far you making things harder and aren't telling us anything new. Which means it is not worth using.

5 / 5 (5) Apr 18, 2012That is correct, hence it is reasonable to assume that they do not shrink. However, when measured in a moving frame, the measurement is reduced. The geometrical explanation of SR shows how those two requirements can be reconciled.
Correct, Lorentz's postulate of physical deformation was always an ad hoc phenomenon and became unnecessary when Einstein and Minkowski provided the alternative model of Reimann geometry.
The universe is not required to be "convenient".

4.9 / 5 (8) Apr 18, 2012BTW, Zephir also answered this one correctly. The fundamental physical reason for length contraction and time dialation (and hence the wedding of space and time) is the limitation on the speed of light, and by extention the value of alpha.
That any self styled physicist should demonstrate such a failure to grasp basic, freshman level physics is pathetic beyond belief. Then again, frozen chickens can't do math.

5 / 5 (5) Apr 18, 2012The difference between the coordinate rate of the clocks and the proper rate is roughly 38.7us per day. That is compensated by a digital synthesiser on the satellite. If the distinction between coordinate and proper time was unnecessary, the circuit would be unnecessary too. Distinguishing them and using GR to calculate the value is what allowed the engineers to design the circuit.
Fleetfoot
4.2 / 5 (5) Apr 18, 2012The path of the light is not vertical as you say, it is the hypotenuse of a triangle created by the arm and the distance it travels while the light is in transit. The "magic" is Pythagoras' Theorem which says that the hypotenuse is longer than the other sides. The invariance of the speed of light means that the longer distance takes longer time therefore the photon clock would tick more slowly. That is simple geometry and valid regardless of whether you treat time as a dimension or not.
Are you saying you don't believe in Pythagoras' Theorem?

5 / 5 (7) Apr 18, 2012They showed it was losing energy at the rate predicted by GR to within 0.1%, that is the difference. You don't seem to understand that science is quantitative. That is why they were awarded the Nobel Prize for the measurement.
There is no "discussion", they made an accurate measurement which matches the predicted value, those are the facts.

1 / 5 (5) Apr 18, 2012I looked it up and while you might be more right, the argument could go the other way as well:
a : a quality or trait belonging and especially peculiar to an individual or thing (you)
b : an effect that an object has on another object or on the senses (people are an "effect")
c : virtue 3
d : an attribute common to all members of a class (you)
This goes to my point about temperature. How does space register as a property, if it is not manifesting some degree of thermal energy? Temperature seems as fundamental a property as time/rate of change. So why not also insist space doesn't exist on its own, but is part of the property of space-temperature/vacuum fluctuation?

1 / 5 (5) Apr 18, 2012It is the blocktime interpretation of spacetime. What makes the ideas such as time travel through warped spacetime possible, since those other events have to exist in order to access them.
Multiworlds has to do with relating this inherent determinism with the probabilistic nature of QM, by arguing that all possibilities do exist in distinct realities. On the other hand, if we view time as effect, it is the collapse of probability which yields determined effects, the future possibilities collapsing into actualities.
The laws which determine outcomes may be deterministic, but the input is probabilistic, since input could arrive from opposite directions at C, so all input into any event cannot be known at any single location, prior to that event.

Because you can't have temperature without movement through space-time but space-time does not need temperature. Vacuum fluctuations are another matter not related to temperature. At least I don't it does.
This is just spitwadding as I am not a physicist but I am thinking that vacuum fluctuations are an emergent property of space-time vs. the Uncertainty principle.

However (I'm sure you knew a "but" was coming) you also appear then to believe that there are no formative forces, dynamics, fundamental attractors, underlying hunan behaviours - consciousness must be an epiphenomenon to you, right? The term psychodynamics may well have had an early origin, it still has universal applicability in refering to the Dynamics of the Psyche, unless of course, you subscribe to the neuricentric paradigm, like Francis Crick who believes (1994) that consciousness is entirely due to neuronal activity and that its centre is probably congruent with the anterior cingulate sulcus of the cortex.

Not relevant as that can't happen due to the Uncertainty Principle.
The Universe does not need us to exist.
So then electrons mean we don't have time according to that idea.
Without time there can be no change. No change in the real world means you didn't look. Change happens. Since that first moment of the Universe there has been change. No change is impossible as that violates the Uncertainty Principle.
I will ask you the same as I ask Sorli:
What do we get from by replacing time with change besides very awkward equations and conversations?

1.4 / 5 (9) Apr 20, 2012Please don't use the word "proven"... science is not in the business of proof it is in the business of evidence.

So what? You can't follow a hypothetical?
What does that mean, I didn't claim anything of the sort...
What? What are you talking about? When I say no change I mean NO change, universally, not just to a particular thing. I'm not talking about electrons, I am saying that if ALL change in the universe ceased then it would be equivalent to and inherently indistinguishable from the cessation of "time".
Deathclock
1 / 5 (7) Apr 20, 2012Yes, and without change there can be no time, they are fundamentally linked as one is a measure of the other.
When I say "no change" I mean NO CHANGE, if you are taking that to mean "well, there was change, you just didn't look" then you aren't following the argument. Entertain the hypothetical regardless of whether you believe it to be possible (for the record, I know you cannot stop all change, if you did you would not be able to start it again and the universe would cease to exist for all intents and purposes).
I agree, change is what ACTUALLY happens... time is a concept used to measure it.

Deathclock
1 / 5 (6) Apr 20, 2012You're right, let's just be dogmatic and maintain the status quo for the hell of it, even when it makes a lot more sense to consider change the thing that is physical and real and "time" the conceptualization of it's measurement.

1.7 / 5 (7) Apr 20, 2012What has been proven is that a constant speed of light creates correlations between acceleration/gravity and clock rates, bending of light etc. It doesn't necessarily prove the whole blocktime/4th dimension as physically real, spacetime as causation hypothesis. The leap from the mathematical description to the physical hypothesis is similar to the leap made with epicycles, from mathematically describing the patterns of the stars, to assuming they are attached to giant cosmic gear wheels. It is this blocktime assumption that leads to the whole wormholes panpoly. You can't travel to other times, if they get erased by changing configuration of the manifesting energy. Information does get destroyed by the creation of new information.
Gawad
3.3 / 5 (3) Apr 20, 2012FWIW, I'd like to mention that I actually AGREE with this, DC. It's one of the reasons I've come to believe that space-time is "emergent" (in a similar way to things like temperature, pressure and "solidity") and rather than fundamental. In a deeper sense, that time and space results from the actualization of the fundamental principle of conservation of energy/mass WRT quantum position and momentum. BTW, that doesn't mean S-T is an illusion or that it can go away somehow. So while you could say time and change are synonymous, this also serves to make Eth's point that swapping time for change is a useless shell game. And, importantly, GRAVITY throws a nasty wrench into the picture of your hypothetical static universe, making it impossible.

2nd, anyone who says that gravity "allow the expansion of Universe with increasing speed" isn't serious, so has yet to make a point. A CC ISN'T gravity, even though it acts against gravity. Dark energy *appears* to be a CC that results from negative pressure, NOT anti-gravity or gravity reversed or any other kind of popular fantasy you care to wave around. So basically, you're not even asking the right question!
Finally, with gravity, even if you were to start with a hypothetical mature STATIC universe, it wouldn't stay that way. You'd immediate have macroscopic bodies FALLING towards each other, or they'd have to ORBIT. Static...NOT!
Terriva
1.1 / 5 (9) Apr 20, 2012End of story, this is simply how the science works.This is entertaining non-sense. Universe is not a living animal. In addition, static Universe doesn't mean Universe without motion. It allows the galaxies being recycled in full depth, for example. It just lacks the metric expansion of space-time and it explains the red shift with dispersion of light at the density fluctuations of vacuum, that's all. Such a model naturally leads to the even horizon, inflation model, etc..

There's a lot more to it than just redshifts at this point. In support of Big Bang theory are also the CMB, proportions of primordial elements (H, He and Li), and stellar and galactic evolution.

3.5 / 5 (2) Apr 20, 2012Posssibly. You may very well be right about that. In the sixties it was all S-Matrix and all that, which is hardly more than a historical curiosity today. But the thing is that for the last 30 years, fundamental physics has made little progress (at least as compared with the first two thirds of the 20th century), and we know there are big, big pieces seemingly just out of reach. So I hardly think it's a waste of time to explore such avenues, especially when you compare that with all the time and energy that went into string theory, only to culminate in the revelation that, essentially, "anything is possible".

Luckily they can make those decisions for themselves, without having to digest your reems of babble on the nature of free will. Can you imagine a scientist submitting a proposal for funding based upon his 'intuition'?
Ive got 300 words left. When philos of the past have made useful contributions to science they were doing SCIENCE, not philosophy. This is another good dividing line between the 2. Einstein explored philosophy when he was young but, finding nothing he could USE, abandoned the effort.

3.6 / 5 (5) Apr 20, 2012Hopscotching from one crackpot site to another to support your delusions won't a scientific claim make; I never said there are no problems or unresolved issues with BB theory. But the static universe model is much worse and utterly discredited. For one thing, no "matter recyling" mechanism that makes any kind of sense (that doesn't require magic) has ever been found, either in theory or in reality.
This is a dead horse that only children who are afraid of the night can't let go of: no crackpot, the world has not always been and will not eternally be the way you wish it to be--as it is now--just because you can't really imagine that things could be other than as you see them over the spark of your life.

Russkiycremepuff
1.6 / 5 (7) Apr 20, 2012Deathclock is correct, in so many words. Time is but an "instrument of measurement" of one event towards the next event. The event is the "change" that differentiates one event from the other, and the "time as a measurement" crosses the boundary from the first event to the next, or the ones after that.
Time is not dimensional as height, width, depth and breadth. It cannot be because time cannot be built in three dimensions as in geometric form. Time is an inherent invention of the human mind to make order out of chaos, and sense out of confusion.
When you speak of time, you generally speak of it as a dimension that has incremental properties. that are finite as nanoseconds, seconds, minutes, hours, days and night, etc. As humans, you have given those properties to time, not merely for your own convenience, but also to account for differences of a global nature.

1 / 5 (8) Apr 20, 2012At the proximity the observable reality is complex and fractal, with maximal complexity at the distance scale, corresponding the wavelength of CMBR (~ 2 cm). With both increasing, both decreasing distance scale the character of observable reality changes: the random complex objects are changing into regular spheres, driven with simple laws. But if the distance from human observer scale increases even more, then the Universe appears random and fuzzy again.
If we could see only the objects million-times larger or smaller, than the human observer, then the Universe would appear quite funny: it would be composed only from spheres, nothing else. It's very prominent behavior. Now the question simply is - how the Universe should behave for to appear like the spheres at small and large distance scales and like the random fuzzy objects at all another scales?
Russkiycremepuff

Yes, the event, or events, add up to a "change" in configuration no matter what type of event it may be. A supernova is an event due to a change in the star's configuration. All events that have some sort of change in configuration is still a change for each particular event.

Without dense aether model such insight is very difficult to imagine, not to say about some timeless model of Amrit Sorli. The AdS/CFT correspondence is based on similar insight: the topological inversion of the space-time, which is behaving like the Klein bottle or Mobius strip here.
It means, you're not required to believe in geometric nature of the space-time - but after then whole areas of modern physics (the topological geometrics in particular) will remain cryptic secret for you.

3 / 5 (2) Apr 21, 2012Change is local. At present even in the SR sense as no information has ever been transmitted at FTL.
Change has a RATE that is measured against time. Time-space is a constant, change is variable. Yes I meant it CONSTANT. In the form of the rate of movement through space-time is fixed. Faster through space slower through time and the total of the two is always the same in comparison to the Universe at large.>>

Now if you can manage to fit change-space into equations of elegance then you will have done something. If you just make a bloody great mess as Amrit keeps trying to do you will be straining, that is ignoring Occam's Razor.

He is going on about numerical order of change BUT the order is TIMELIKE and he his thus just engaged a philosophical circle jerk.
Except that it doesn't make more sense and produces awkward math that just tries to hide the timelike nature of change.
Go ahead and try to fix that constant of SPACE-TIME while using change without simply hiding time and doing it awkwardly at that.

5 / 5 (4) Apr 21, 2012As Noumenon already pointed out, this is completely untrue. Length contraction is a part of special relativity, hence there can be no contradiction. Here's the proof:
Let the length of the clocks be L at their rest frame X. Therefore one 'tick' is T = 2L/c. Let the speed of the clocks be v relative to X. According to special relativity, the length of the horizontal clock is
L' = L*(1 - v²/c²)
Therefore one 'tick' of the horizontal clock observed from X is
T' = 2L'/c = 2L*(1 - v²/c²)/c = T/(1 - v²/c²)
The length of the vertical clock does not change, but the photon must travel a greater distance relative to the horizontal clock. The photon path is given by:
cT" = [4L²+(vT")²]
Cont~
Ethelred
3.7 / 5 (3) Apr 21, 2012But first tell us why we should replace the present system with something that looks ugly awkward and adds nothing. I say nothing because you have consistently evaded the question of what it adds thus implying there is nothing.
Ethelred
kvantti
5 / 5 (5) Apr 21, 2012From where we can derive the length of the 'tick' of the vertical clock observed from X:
T" = [4L²+(vT")²] || ( )²
c²T"² = 4L²+v²T"² || -v²T"² , :c²
T"²-v²T"²/c² = 4L²/c² || 4L²/c² = T²
T"²(1 - v²/c²) = T² || : (1 - v²/c²) , ( )
T" = T/(1 - v²/c²) = T'
Which is same as the 'tick' of the horizontal clock which has undergone length contraction. The authors of the paper are therefore incorrect and their whole research is based on misunderstanding of special relativity.

The moving length contracted horizontal light clock ticks at a rate (in respect to the clock at rest):
T' = 2L'/c = 2L*sqrt(1 - v²/c²)/c = T/sqrt(1 - v²/c²)
Where L is the rest length of the clock. The vertical clock - which has not undergone length contraction - ticks at the rate:
cT" = sqrt[4L²+(vT")²] || ( )²
c²T"² = 4L²+v²T"² || -v²T"² , :c²
T"²-v²T"²/c² = 4L²/c² || 4L²/c² = T²
T"²(1 - v²/c²) = T² || : (1 - v²/c²) , sqrt( )
T" = T/sqrt(1 - v²/c²) = T'
Which is the same as the 'tick' for the length contracted clock, as it should be according to special relativity.

5 / 5 (3) Apr 23, 2012The answer is simple if you can think in terms of spacetime being a 4-dimensional manifold. Clocks moving through spacetime measure in the same way that an odometer measures the distance travelled by a car, the result is dependent on the path.
In Newton's view, they should have measured in the same way that am altimeter works in a balloon, it registers the altitude regardless of horizontal movement.
The difference between coordinate and proper time are that proper time is measured along the path, regardless of how it curves due to acceleration. Coordinate time is the difference between the beginning and end events projected onto one specific axis (i.e. the dot product).

Philosophy of course includes theoretical physics - I wonder if any respondents here have read "Theoretical Physics" by Kompanyets, a favourite in my library. Of course, conceptual terminology like dialectical materialism and logical positivism don't mean a thing to those who do not know how they have shaped our modes of approach in modelling reality... It shows rather clearly in their scientistic, trite formulations of thought.

If a single mathematical theory predicts correct results for many different phenomenon and experiments - and contradicts none - then the theory is effectively a correct theory for describing reality and all metaphysical arguments concerning the theory are moot unless you can prove it theoretically (with math) and empirically by experiment.
E.g. in this sense all the interpretations of QM have been irrelevant (for physicists) up to these days, but now it seems such experiments as "delayed choice quantum eraser" and "quantum interrogation computing" have been hinting that the Copenhagen interpretation is false since it can't bridge the gap between decoherence and re-coherence of quantum states.

Because the light would spread more slowly trough such dense vacuum, the speed of laser clocks would slow down too. In another words, these neutrinos would act similarly, like the relativistic dilatation of time inside of gravity field.

Take a look at the Einstein field equations or the stress-energy tensor. Do you see an inverse square of distance somewhere in the equations?

In it's simplest form the mass-energy density of a spherical stellar body is simply 3(mc²+E)/4pi*r³ where m is the rest mass of the body, E is the total sum of thermal and electromagnetic potential energies of the object and r is the radius.

It doesn't matter Newton used G first, it is an universal natural constant that, as Fleetfoot said, "is nothing but a conversion factor related to the SI units of mass, length and time. GR is derived without it but we use that factor to convert the results to m/s^2 per kg."
...and in Newton's theory of gravitation P_e = G*(mM)/r. Btw. sqrt(rc^2) = sqrt(r)*c (or if you meant sqrt[(rc)^2] it is just rc...)
Fleetfoot
5 / 5 (1) Apr 25, 2012No, like any other density, the mass-energy density is the energy (including mass) divided by the volume.
And there you have a perfect demonstration of how clueless Callippo is on maths, G is a constant like "1 inch = 25.4mm" and appears anywhere you want to convert gravitational units.
Fleetfoot
5 / 5 (1) Apr 25, 2012The factor 2G/c^2 converts units of radius into units of mass, nothing more. In consistent units, we can say the mass of the Earth is 8.9mm but most non-scientists would find that odd. What matters is the ratio of mass to radius so in consistent units, G is superfluous.

5 / 5 (3) Apr 25, 2012The proof has been around since 1660, or 1678 if you couldn't do anagrams in latin. It is Hooke's Law as I said, trivial schoolboy physics. The length of a rod subject to a stress far below the elastic limit is increased in proportion to the tension and it is constant, it doesn't grow with time.

5 / 5 (3) Apr 26, 2012Try to find out a little about the subject before posting. Spaghettification elongates an object and thins it at the same time. The stretch factor is the square of the thinning so the volume is unchanged.
The changes are caused by the tidal force as the object nears the gravitating body so at any distance, the amount of change is determined by Hooke's Law up to the point of tensile failure (and this may be outside or inside the event horizon for a black hole).
Fleetfoot
not rated yet Apr 26, 2012The paper talks about a metal bar increasing in length and that is goverened by Hooke's Law. It's clear you don't follow this even in the aether model so let me explain it for you.
Think of a 1m rod free floating in space. Aether theory said light was waves in a crystalline substance which fills the universe so assume the rod happens to be at rest relative to that. Assume the aether has a temperature which is rising causing it to expand, the Hubble Constant gives 6.5nm per century over the 1m rod.
If the ends were unconnectedand both at rest in the aether, they would move apart at that speed, but an initial speed for one could cancel that out and simple inertia means there would be no force needed to maintain that condition.
(contd.)
Fleetfoot
not rated yet Apr 26, 2012If the aether dragged on matter, the planets would not orbit the Sun but would slowly spiral in as they lost orbital energy. That is not seen but we might speculate that there is a small effect beyond our ability to measure. If that were the case, the 6.5nm per century difference in the motion of the aether past the ends of the rod would create a tension in it and then Hooke's Law applies. Of course the value would be ridiculously small but in theory it would be non-zero. My original point still stands, that effect would be constant in time, not cumulative.
In the actual paper, they are not talking about a mythical aether but simply the Hubble expansion. There is no linear space "drag" in GR.

Philosophy is a continuing education that connects to science because science is always in flux, always changing. And the rationality of philosophy helps us to understand those changes in science. Philosophy gives us the 6 questions of: What; Why; Who; Where; When; and How. Science alone does not. Science only gives us possibilities, such as: Can it; Will it; Could be; Might be; Should be; etc. "

2.2 / 5 (10) Apr 26, 2012Kant mistakenly felt he had to choose one over the other; science over faith to procure knowledge. But faith is often mistaken for belief, although the two are quite different. Faith is not limiting itself to events or occurrences; while belief does. Belief in an afterlife is a certainty of its existence; but faith is merely hope in its existence. It is possible to have faith and also procure knowledge of science.

1 / 5 (7) Apr 26, 2012Neither is physical matter or its velocity dependent on time. The mass, size, and amount of gravitational force of the matter as the cause may affect the steady forward flow of time, but only on a temporary basis. Time stands as Zero or Null everywhere in the universe and everything else has dimension. We cannot go back in time, only forward. If time were a dimension, then it could possibly flow backwards, BUT only if it had memory capability to reverse itself to the previous level. For that to happen, the "space" and all matter, etc. that has moved on will have to return to the same as though it had never left and, quite so, it indeed had never left.

Fleetfoot
5 / 5 (3) Apr 27, 2012In relativity, real clocks produce a fixed rate of ticks per unit of proper time regardless of their motion through space. They measure time in the same way that the odometer in your car measures distance, the length of a worldline depends on its path through the 4-dimensional manifold.
If you project the ticks of a clock onto the worldline of another clock using the vector dot product, the projected ticks will be spaced more widely than those of the clock onto which you are projecting creating the effect known as "time dilation".
Again, this explanation is simple undergraduate material and has been known for over a century.

You are as ignorant of my middle name as I am of yours. That is not ridicule, just a statement of fact regarding absence of specific knowledge on both our parts. Your lack of knowledge of basic physics is a major impediment to serious conversation on the subject.
Fleetfoot
5 / 5 (2) Apr 27, 2012I agree entirely, your character is of no concern and neither is mine, however what you know or not is very relevant.
"Dispersion" means that ripples launched with frequency f1 arrive with the frequency f1 and ripples of frequency f2 arrive with frequency f2 but they travel at different speeds.
A redshift factor z means that ripples launched with frequency f1 will arrive with frequency f2 characterised by the factor z defined by
z = f1/f2 - 1
Clearly they are not analogous and the fact that you don't know what phenomena the words describe is relevant.
Origin
1.5 / 5 (8) Apr 27, 2012You have arguments - or you haven't. That's all.During dispersion the speed of waves can change as well. The change of speed will be perceived as a change of frequency from intrinsic perspective of the observer, who is using the same waves as a measure of time. The duality of both perspectives is what is characteristic for dense aether model.
Origin
1.6 / 5 (7) Apr 27, 2012For example, the gravitational lensing of black holes can be perceived in two dual ways as well. From extrinsic perspective the space-time remains flat and what is changing is the speed and direction of light waves. This perspective is quite common and everyone imagines the gravitational lensing in this way. Unfortunately, this perspective is not consistent with general relativity, in which it's the space-time, which gets curved - not the path of light. The relativity clearly says, the light speed is invariant, so that the light always travels along straight path trough space-time and it cannot be refracted. What is changing is the frequency of light, after then.
Fleetfoot
5 / 5 (2) Apr 27, 2012There is ample evidence against it but first you need to understand what the term "redshift" means.
No, the term "dispersion" specifically means they travel at a speed which depends on the frequency but since the frequency doesn't change, the speed doesn't change either.
These are two independent and quite different effects. The evidence that rules out Tired Light will not make sense to you if you think the term refers to speeds when it actually refers to a change of frequency.
Fleetfoot
5 / 5 (3) Apr 27, 2012The frequency from the perspective of the source galaxy is the same as produced by the same atoms here. The frequency we receive is reduced compared to that, similar to the Doppler Effect.
The local speed of light anywhere is determined by the local refractive index, it determines the wavelength as a function of frequency but it cannot alter the frequency.

5 / 5 (1) Apr 28, 2012If "redshift" means "change of frequency" to me but "change of speed" to you, any arguments I produce will seem irrelevant to you even if they are perfectly valid from my point of view. Terms like "redshift" are only useful if they carry the same meaning for both of us, that is the basis of language.
There need be nothing subjective involved, we can agree to both use a definition from a third-party glossary and as long as we agree the same definition, we can have a meaningful conversation. As long as our definitions differ, there will only be confusion.

5 / 5 (1) Apr 28, 2012What I am saying is that there is no point attempting to discuss interpretations until we first agree what it is that is being interpreted. The word "redshift" refers to a difference of frequency between locally produced spectral lines and those observed from distant sources.
Your aether model is nothing more than that of Lorentz hence it is at best equivalent to SR and has no way to model expansion, it is not a metric theory. There is no explanation for redshift in LET other than Doppler.
I intend to return to the Doppler topic once you agree what "redshift" means.

Philosophy is not metaphysics. I thought I had made that clear when I said that "metaphysics in itself cannot be a science due to its inability to produce cold, hard facts. It may have the potential to do so, but at this time, it is based only on belief and belief is unscientific unless founded on incontrovertible evidence. Philosophy is not based on belief or faith.

For time to go backward, everything in universe would also be required to reverse their course, and the laws of thermodynamics would also be reversed and could not repair to its present or future, until time resumes its forward motion. There is no "motion" of time despite all clocks manufactured. If time had motion, it would create continuous warps in space that would demolish matter and energy. The only thing that could possibly control the motions is gravity, and it would have to be a "super" gravity to keep time in check.

Laws of thermodynamics are all based on, and rely upon, dimensional qualities of matter, energy, space, gravity, EM, et al. Even DM and DE must have dimension. You may take a circle, a perfect circle, and you may turn it, without breaking the circle, into a triangle, rectangle, square, and any other geometric design you wish as long as you do not cut the circle. The flow of the circle into angles does not depend on time because the geometry is closed. It is still a circle with dimension, and nothing has really changed. Nothing goes in and nothing comes out of the circle or whichever other geometric form it is pushed into. The form is three dimensional if you transport height, length, and depth to it so that it is no longer flat.
But time, even if it were a dimension is not involved in creating this sphere. Other influences create the sphere from the circle, because time flows onward, while the sphere, such as

Laws of thermodynamics preclude going backward in time for supernovae. That alone is able to convince that time is not a fourth dimension. The supernova will proceed according to its principles of gravitation and repulsion of matter and energy. It cannot go backward to its former self after it has gone through its motions and has no recollection of itself as a star.
As I have said before, time has no memory of its previous level, and therefore cannot influence bodies of matter and energy to go backward. All of your fancy Laws will not change this fact because time is an abstract.
My feeling is that clocks are actually influenced by the gravity drag and EM in space, which is why electrons and other particles are influenced by the EM and gravity (or repulsion) in their own microspace.

Nor do I. When you drive a curved path across a flat field, the odometer records the length of your path. A clock works the same way, it doesn't only measure how far north you have travelled.

But they do not understand that time has no memory of the past. Events are vanished and do not simply go into some kind of file that can be pulled out later to view and experience again. Those files are only in brain's memory cells of the observer, but not in the time. Time has no vector that can be determined as to the position of one point in space relative to another point due to its lack of dimension. However, transfer of matter and energy from one point to another IS possible through a method of dissolution or dissociation, and then recreation or recombination of that matter and energy. The time involved may be measured in such experiment, but time is otherwise unnecessary.

It is not going to stop with the stopping of events and the changes that events create. Time has no evolution because it is not dimensional. It has existed before the universe came to be, and it will still exist long after the universe is gone, or has recondensed. Time is endless and while it behooves you to place limits on time, it is an exercise in futility except for the measurements we use for human convenience.

It also has nothing to do with creationism, for it has no intelligence or will. It is not an energy as we know energy since observable and detectable energy is an emission of matter and forces such as gravity and EM. The only force that time is capable of, is its onward "flow". This flow is unseen. We cannot detect it and it is not quantifiable. It occupies "adimensional space" everywhere in the universe, but not as the same as everything else that occupies normal dimensional space. It is not a spirit or ghost either, but it IS a Force.

They all relate to each other in some way, but time does not relate to these things because time is outside of the sphere of influence of such objects. Time is not a plasma, gas or anything related. I believe now that the closest I can come to describing this thing called time is "thought". Of course, thought and ideas stem from chemical processes in the brain. But the next question for that is: does the chemical processes in the brain cause the thoughts and ideas; or do the thoughts and ideas cause the chemical processes to facilitate the thought process? Where does thought come from? And where does time come from? It is possible that time and thought are the same, even though it seems impossible, but it only seems to be. And no, I am not delving into metaphysics with this explanation. I try to be purely analytical and observant of all aspects.

1.6 / 5 (7) Apr 30, 2012Many people believe that the oldest galaxies are closest to the point of the BB, the point of origin of 3Dimensional objects. But it is the galaxies that were made after the BB from the matter and energy that "came out first" and therefore, had the highest velocity to reach the furthermost depths of the new universe. When our telescopes see the red shifting of galaxies, it is those that left the origins ahead of all others. If not for the red shift, we would think that they are still closer due to their light reaching us long after those galaxies had moved on.But in any case, they will also be the last to return to the point of origin. First to leave and last to return.

1.6 / 5 (7) Apr 30, 2012Sir, YOU are the scientist, not I. As has been said before, time dilation occurs in the presence of mass due to gravitational force. Time is a different kind of force, as it flows forward from present to future (Zero to one, Zero to one, endlessly), but never backward. While it is not a dimensional force, it still has a capability of slowing down slightly as it collides with mass and energies, but regains its linear movement. Other forces such as EM can go through mass and emerge elsewhere. Time cannot do that, but it flows on its own Adimensional space. That space is smooth and is somewhat attached to normal dimensional space so that time is able to interact with mass, even slightly. In fact, I have been wondering if that A. space is the DM and DE that we seek.
Russkiycremepuff
1.6 / 5 (7) Apr 30, 2012But let us go back to the beginning, the singularity. Within that singularity was 3D mass and energy, other forces had not been created yet. IF time had been within that singularity, it too, would have been dimensional and that is ridiculously impossible. Therefore, time and its own A. space were OUTSIDE of the singularity and were established already in some kind of preparation for the new universe. It may have happened many times, or just once.
Time is incremental, always flowing from present to future, whereupon that future becomes the now, or present and time resets back to Zero. It IS a force due to its flow, but its flow is not dependent on anything but its being carried on its Adimensional space.
Russkiycremepuff
1.6 / 5 (7) Apr 30, 2012Time, as we know it and measure it according to Velocity and distances, use it as a utility. Likewise, I believe that at moment of Big Bang, all the contents of the Singularity also used time and A. space as a utility to explode out of its origin and, following the linearity of the A. space in all directions, the 3D space and A. space joined together, a bit loosely due to the matter that carried with the force of the explosion or inflation of 3D space. Time was already everywhere, everywhere that its A. space was in place, that is.
Now, it is for you scientists to find that Dark Matter and Dark Energy. Those are the matrix which enables Time and are eternal.

Again that is accurate, cosmological redshift is interpreted as a consequence of the Friedmann equations which were first found as a solution to GR. Doppler is a good approximation over shorter distances but for high redshifts the exact gravitational interpretation is required. That is why it is often noted that it is more accurate to describe space as expanding rather than galaxies moving through space.

This is from 2010 and regards "time dilation" and its absence from quasars, but not from supernovae.
"One of Hawkins possible explanations for quasars lack of time dilation is that light from the quasars is being bent by black holes scattered throughout the universe. These black holes, which may have formed shortly after the big bang, would have a gravitational distortion that affects the time

1.7 / 5 (6) May 02, 2012It is important to also remember that the Adimensional space is not absorbed or enters the BH, or even remains near it. That is because an Adimensional object has no gravitational force of its own and is only mildly affected by a dimensional body's gravitational attraction due to the slight clinging of the "fabric" of 3Dimensional space to the fabric of Adimensional space. The same holds true for the 3Dimensional space. It does not enter into BH, For 3D space to enter into vicinity of BH and enter into its influence, that 3D space would have to separate itself from the A. space and then it would be lost into the BH. But because it "clings" to the A. space, it proceeds along with the Adimensional space on which Time moves along with both of the spatial entities or objects, i.e., 3D space and A. space. Only the matter/energy of mass, etc. can enter the BH but not the space.
Russkiycremepuff
1.7 / 5 (6) May 02, 2012I do NOT believe in time dilation in the presence of 3D mass and energy. There is very little influence on time, if any, by matter/energy. Time and 3D mass/energy are not related to each other, and time and the spatial fabric simply goes around the mass to emerge on the other side and keeps going.

But. the Dark Matter and Dark Energy I believe to be another aspect of the fabric of Adimensional space. If I am correct, then that fabric of A. space will not remain in Sun's vicinity or within it, but will likely divide similar to jelly and then join back together on the other side of 3D object. So too with all other 3D objects that it encounters without any time dilation.

The title is misleading, it refers to an attempt to measure something equivalent to the stretching of supernova light curves but in quasars. The technique uses a Fourier Transform and the evidence only shows they haven't measured the lowest frequency components yet. They need about 200 years of data to do that reliably so don't hold your breath.
Fleetfoot
5 / 5 (3) May 02, 2012This is self-contradictory. If "there is no 'relativity'", the speed would be frame dependent as described by the Galilean Transforms, it cannot be invariant.

Time is here only a numerical order of duration of material change.
Smaller the number of numerical order measured by the clock, slower the velocity of material change.
Twins get older only in a 3D quantum vacuum not in space-time which is only a math model and has no physical existence.
I see my work here is not rely fully understood: I do not deny existence of time, time we measure with clocks exist; time is a numerical order of duration of change that run in a 3D quantum vacuum. Definitely time has no physical existence as a medium in which change run. I hope this will be clear soon to all.
Fleetfoot
5 / 5 (2) May 02, 2012Part of that may be because English is clearly a second language for you. Reading the book I recommended will help you learn the technical terms accurately. For example:
It is not "invariant in all inertial systems", instead "invariant" means it "has the same value in all inertial [coordinate] systems".
That may have been what you meant, it's hard to tell.
That is not disputed, the difference between the 3D and 4D interpretation is whether the measurement is path-dependent.
What you are saying is clear but is contrary to the experimental evidence supporting GR.

Those other parts could be measured by ordinary timepieces also, as on Earth, but the term of the hour and the day may have to be modified due to actual length of hours, days and years in different locations of the universe. The change from future to present is not dependent on time because that change is dimensional and time is non-dimensional. It merely measures the change or event, and as time flows, it - cont'd

You said " time as a utility is used .. to measure an event or a distance (the given physical phenomenon) within the assigned parameters of specific 'blocks'". While a ruler can be used to measure distance, the period between colour transitions acts as the "blocks" or base units for measuring duration.

1.7 / 5 (6) May 03, 2012Mr. Sorli is correct that time has no "particular" speed, although it does have an unquantifiable speed that may never be determined with our present technology. Because time is unconnected to normal 3D space and only 'flows' on its Adimensional space fabric, Time can continue on its own speed which is outside of our frame of reference, for now.
The insistence of Aetherists and others that time and 3D space fabric are somehow entwined is illogical. If that were the case, then time would not flow smoothly and would stop and start and then rush madly off to join the speed of light. In that case, time would be wholly dependent on the speed and machinations of every 3Dimensional object it encountered and the universe would be in a herky-jerky motion because of it.

That cannot be because changes are always occurring and any and all changes will occur without the need for time except as utility. I have mentioned this enough times, I think.

5 / 5 (2) May 04, 2012Not "proportion", they must be of equal duration, equal amounts of time. That is what I meant by "regular", Newton used the word "equable", or at least that is how it was translated.
You go too far. We can class the clock as being in one of two states, "blue" or "clear" at any moment. Times are measured only by counting the number of occassions that state changes say from clear to blue during the interval to be measured.
However, you are still missing the point, time can be measured by state changes alone.

again some magic properties of time....what for ?
time is numerical order of change in this real 3D physical space which originates from the 3D quantum vacuum. Time is real as much as change is real.
Time is a numerical order of a duration of a given physical phenomena which run in a 3D quantum vacuum. At the Planck scale there is no time, physical phenomena are immediate. By the immediate phenomena as EPR and gravity information and energy transfer are carried directly by the fundamental grains of a 3D quantum vacuum. Motion of light in a 3D quantum vacuum has its time, at the photon scale there is no "relativity" yet; velocity of light is invariant. "Relativity" starts at the scale of the pi meson.

"However, you are still missing the point, time can be measured by state changes alone." - Fleetfoot -
Yes of course. The changes do not depend on time, except as measurement of distances and durations. Time itself cannot be measured; only the thing itself is measurable by time as we know and understand time. Time is actually elusive in its continuous flow in (or on) Adimensional space fabric. We should understand that there is a "flow" of time, but we must build clocks and rulers and regulate the methods of precise measurements in order to "harness" the time in precision

1.7 / 5 (6) May 04, 2012It could be said that Time "rides" upon its Adimensional space fabric continuously and avoids 3D spatial matter and energy but not the 3D space itself. We cannot "detect" Time itself even though it does exist and is everywhere.
You still equate Time with change and vice-versa, but changes can occur without the influence of Time, or rather your concept of Time, unless you are continually looking at your timepiece to measure durations of change.
Tachyon, there is no phenomenology in Adimensional Time as related to changes, and so there is no inseverability clause, as you succinctly put it without the "clause". Any "variable transform proportionalities" are not Adimensional Time dependent, only on the watch or clock that measures your concept of time.

1.7 / 5 (6) May 05, 2012Mr. Sorli, I have already stated in previous comments that Time and its accompanying Adimensional fabric of space, were OUTSIDE of the Big Bang Singulrity even before the great expansion or explosion of all matter and energy outward in all directions. IF the Time had been within the Singularity object, then time would need to be also 3Dimensional and would have exploded outward along with all other objects in that first nanosecond of the "explosion". For Time to be locked into that Singularity, it would need to interact with all forms of matter and energy as another form of energy. IF time were 3Dimensional, it would be readily seen in whichever shape or form it would have taken. Also Logically speaking, if Time cannot be seen or detected with any of our senses or with mechanical instruments, that means that Time is NOT 3Dimensional, and therefore, it has no form and cannot interact with 3D objects or space.
Russkiycremepuff
1.7 / 5 (6) May 05, 2012When you say that "Time is a numerical order of a duration of a given physical phenomena which run in a 3D quantum vacuum.", that is not in dispute. But I believe there is more to Time and its existence in Adimensional space than in 3D space.
From your own description, you appear to have given an assignation of Time as a 3Dimensional object or entity which exists as a "numerical order of the change in duration" of something. How do you account for this temporal ability? Does it have some sort of intelligence with which to accomplish such a feat? And when and how do you know when and if the Time has accomplished such. You only say that Time is a numerical order, etc. etc. But WHO is doing the measuring? Is Time doing the measuring?

But in your analogy of universe as pond ripples, you have never stated the ORIGIN of those ripples. In your pond, the ripples or waves flow outward and, presumably, there is a center from which those ripples emerge and flow. The fishes under the waves are not in my question at this point.
But I must know the origin of your ripples or waves; the exact location of dead center where the ripples are from; and why ripples emanate from that center. Are the ripples continuous to flow outward, or will they slow down and possibly reverse? What is causing the ripples?
Please explain your AWT ripples. Thank you.
Terriva
1 / 5 (5) May 05, 2012But the point is, this light get dispersed with distance in similar way, like the ripples at the water surface (the wavelength of light increases), so that the distant light sources are simply unobservable, because the become infrared. Such distance limit doesn't imply the beginning of Universe though - if we would come closer to these distant light sources, we would see them again.
Try to imagine the water surface under slow rain. The fall of droplets at the water surface will become unobservable from the certain point at the surface with surface ripples, when these ripples will get dispersed before they can arrive to that point.
Fleetfoot
5 / 5 (1) May 05, 2012Incorrect, if the source was distributed, then what we see would be the integral of sources from different distances and redshifts so the spectrum would be flattened on the IR side of the peak compared to a thermal curve. What we see is precisely thermal.

I do not know if such terms are appropriate to your pond analogy, but that is why I feel that it is imperative to know your starting point or beginning of ripple formation and their procession forward. You seem reluctant to address this.
What I now mean, is that if you disagree on Big Bang but only believe on randomness of universe and the string theory, then your pond ripples analogy is flawed in that randomness does not create universal ripple/waves, imo. Maybe only local but it still requires a catalyst to create ripples. Therefore your pond analogy could not relate to the natural formation of universe even if universe is closed.
"The origin of ripples at the water pond is the same like the origin of light in the Universe - some wave sources randomly distributed around it."
What is the origin/source of that light?
Russkiycremepuff

To create what we see requires a source which is all at a single distance from us, a very thin spherical shell centered on us.

1 / 5 (1) May 06, 2012The wavelength only changes if the depth of the water changes, the frequency doesn't change at all. When we look at the light from distant galaxies, the frequency is reduced compared to what was emitted.
We call it "redshift" because the frequency is reduced so blue light is moved towards the red end of the visible, but the effect occurs at all frequencies from gamma to low frequency radio astronomy.

Dispersion is a different effect that doesn't change the frequency:

not rated yet May 06, 2012The correct term would be "Compton Scattering". Thomson Scattering classically is similar but is elastic so doesn't reduce the energy. Compton Scattering is inelastic so does reduce the energy and applies when the photon energy is greater than the particle mass:

It is also responsible for the Sunyaev-Zel'dovich effect:

However, the scattering must also change the momentum which would mean space was opaque. Franz Zwicky first proposed Tired Light as an explanation for redshift in 1929 and even in his original paper he noted that this ruled out scattering as a viable mechanism. See "Specific falsified models" here:

Agreed, so the depth is uniform and therefore so is the speed of the waves.
The waves closest the centre have the longer wavelength or lower frequency, those farther from the centre have a shorter wavelength or higher frequency. As the waves move out from the source, the frequency INCREASES which is "blue shift".
Agreed, please try it.
Fleetfoot
5 / 5 (2) May 06, 2012Note also that since the speed is uniform, the waves cannot be "bunching up", the increase in the number of ripples per metre must be due to knew ripples being added between the existing ones. Your explanation relies on the Ripple Fairy sprinkling new ripples into your waves as they move.
For red shift, the Ripple Fairy would be stealing some of your ripples.

With the movement of egg, waves or ripples spread out from that source as contents of broken egg spill outward and ride the crest of ripples/waves going far and faster from the source. This is not randomness. This is beginning of universe and redshifting of waves and egg contents away from broken egg. All the waves are in circular pattern all around the source, and if an observer stands on top of source, in every direction he looks, everything is red shift.

If the speed and wavelength both change, the frequency remains the same so there is no red shift or blue shift.

It seems like you are describing an equilibrium in random creation, degradation, and eventual disappearance (evaporation) of all matter, energies and gravitational forces to return to their basic components only to blend with membrane and then possibly a simultaneous popping up of either the same or other equal subatomic particles elsewhere in the membraneous gas to maintain equilibrium of all mass in the present existence since matter and energy are interchangeable as they can become one or the other, but not simultaneously both.
I can understand the need for an equilibrium on and within the membrane, as ~1/2 of the matter is within that membrane and no more can be created subatomically, unless there exists subatomic particles in preexisting occulting dimensions and I do not think that we wish to go there right now.

Membrane soup is logical, but there is a smack of metaphysics to it, in that the equilibrium that must be kept has to indicate an intelligence of some sort.

In my illustration at fourth comment from top of page, I show that with Fibonacci sequencing, in 2D and you are observer looking from the right side of page toward the Singularity, it seems from your perception that the intervals between the wavelengths are decreasing. Is that correct? But, in reality, they are neither increasing or decreasing. The wavelength remains the same. Similar is a long row of fenceposts in the countryside. When you look down the row from near a post by the road, it appears that the distances between the posts decrease or diminish as you follow the line into far distance. But it is simple optical illusion from your vantage point of looking toward what could be beginning of the row.

5 / 5 (2) May 08, 2012The first thing to note is that "singularity" is a mathematical term which refers to the behaviour of the equations we use to describe the universe, it is not an object. For example y=1/y has a singularity at x=0. In cosmology, it just means the very early time when our maths becomes unstable and cannot make a prediction.
the second point to note is that since the laws of physics are universal (by definition, if they didn't apply everywhere, they wouldn't be "laws"). The conditions that the maths fails to describe happened everywhere at the same time (in the first millisecond after the "bang") so when you say "toward the Singularity", it doesn't really make any sense.
Fleetfoot
5 / 5 (1) May 08, 2012In reality, they decrease (though not the way you show, more later) while in "Terriva"'s picture they increase, his choice of picture is hopelessly flawed, he doesn't understand the phenomenon at all.
Suppose you look down the line of poles and by measuring carefully using parallax, you find they are equally spaced. You also see three cars on the road, the first just crossing the shadow of 10th pole from you, the second at the 20th and the third at the 30th pole.
(to be continued)
Fleetfoot
5 / 5 (1) May 08, 2012Each car has a horn and you know that by law they must all emit the same note when measured by someone standing next to the car when parked.
You have a directional microphone which you point at the first car 10 poles away. You measure the frequency and find it is a little low, then using the formula for the Doppler Effect you work out the car is moving at 20mph.
http://en.wikiped...r_effect
You point the microphone at the second car 20 poles away and note the frequency is even lower. You find the car is moving at 40mph. For the third car the horn note you record is the lowest and you calculate it is moving at 60mph.
When the sound from each car horn is being measured, it is moving through the same air just in front of the microphone so the lower frequencies will have a longer wavelength.
The actual process is slightly different but it is the same as Doppler for objects within a few million light years.
Fleetfoot
5 / 5 (3) May 08, 2012Terriva is claiming that all three cars are actually parked and that thinking they are moving is an illusion. Instead he belives that each time the sound passes a telegraph pole, some of the peaks and troughs of the wave get lost so by the time they reach us, those that remain are spaced farther apart (but have somehow managed to shuffle about so they remain exactly equally spaced).
By a remarkable coincidence, the fraction of cycles lost at each pole is proportional to the number of waves between that pole and the next which gives the illusion that the cars' speeds are proportional to the distance from the microphone.

1 / 5 (5) May 09, 2012In dense aether model it's because the concept of space-time is always connected with some gradient of vacuum density. In dense aether theory the transverse waves cannot spread without such a gradient, the light waves are no exception. With respect to the mass spreading this gradient is behaving in similar way, like the gradient at the water surface with respect to the light spreading and the principle of least action can be applied to it. This model therefore attributes the time to physical dimension of physical object: gradient of aether density, forming the space-time.
Fleetfoot

That energy propagates as ripples in spacetime at the speed of light hence the momentum they carry equals the energy.
In regions midway between two binary systems, where the gravitational waves overlap, they will produce standing waves. Those have the sum of the energies but the momenta being vectors partly cancel thus such standing waves in spacetime have an effective mass density.

You may also want to think about what "dimension" means in our language, I could also say that distance is "only a mathematical dimension, namely numerical order of location". Ultimately, what general relativity tells us (and SR via the geomtrical understanding of the Minkowski Metric) is that space and time are partly interchangeable. However, you look at time must also apply to space.
Origin
1 / 5 (7) May 09, 2012In dense aether model the gravitational waves correspond the underwater density (sound) waves, which are propagating like the Brownian noise at the water surface. Therefore the gravitational waves are still waves in extradimensional hyperspace, but because they do propagate in extradimensions with superluminal speed, they're not detectable like the harmonic wave in our space-time. Instead of it, we would perceive them like less or more sudden changes of CMBR noise intensity/frequency, coming from all directions at the same way.
Origin
1 / 5 (5) May 09, 2012The derivation of gravitational waves from stress energy tensor in general relativity is fringe, because in general relativity these waves are serving as a reference frame for itself (without existence of gravitational wave you have no reference frame defined and therefore the speed of gravitational wave remains undefined).

However Hermann Weyl proved in 1944 already, the Einstein's pseudotensor doesn't exist

Aether wave is, I think, also 3D plus the 3D time and thus in agreement with the SR and GR.

And yet, person (A) with the supposedly stationary clock says that his clock is normal in time and space but that B is running slow. While B is moving, A is also moving away from B and A is subjected to the rotation of the earth in relation to B. They are mutually moving away from each other.

No, SR and GR work in 4D while aether theory uses 3D space with time as a measure of change, not a dimension, that change is why Einstein is famous.
Start with a piece of paper which of course is 2D. Draw a line and call it the X axis. To add a Y axis, just draw another line crossing it at 90 degrees.

Fleetfoot
not rated yet May 10, 2012In SR, you can do almost the same with three axes for space and one for time (showing readings from a clock). In 4D, imagine one line and call it the T axis, then you can add a line at right angles and call it the X axis. The Y axis is at right angles to both T and X, and similarly for Z.
Note the key point here is that there is no unique direction for time in the 4D "hypervolume", its individual time axis is determined by the motion of each clock so two clocks motion relative to each other will not agree on times, even though both are working perfectly.
The duration measured between two events at which a clock is present depends on how it moves between the events. In fact what it measures is the length of its path between the events through 4D spacetime, rather like the odometer on a car measuring the distance travelled regardless of the car's heading, north, east etc..

No, it is a process that appplies to photons, not massive particles.

Ned Wright's stuff is some of the best around but perhaps a bit advanced for this discussion. Think about what I said about the cars and telegraph poles in my previous post.
Right and the same applies to galaxies or the cars passing the telegraph poles. They were moving at 20mph, 40mph and 60mph so each sees the next moving away at 20mph, each hears a lower note from the other's horn.
If you can understand that analogy, you'll understand cosmological redshift.

1 / 5 (4) May 11, 2012I think that this is the basic, primary point of a misconception about time. Causal evolutions (any change of "things") occurs at a rate of change - this implies the existence of Objective Time - despite any subjective perceptions, definitions, or modelling of time. There is therefore Objective Time and Subjective Time, the former is the rate of change in causal evolutions and a fact of cosmogenic ontology; the latter is its psychodynamic perception and human processing. "Time" therefore, is not an imaginary component but a primary ontological attribute. In this sense physical actuality of "things" (which are slow processes) is inseverable from time - Minkowskian perception of "spacetime" conceptualises this. It leaves fundamental paradox/duality: is t foundational, or adimensional space inductive.

where c is the speed of light. That is geometry in my opinion. You said in another post that you "happen to be mathematically challenged" which is fair enough, but you cannot then claim that you know better than every mathematician of the last century.
Russkiycremepuff
1 / 5 (5) May 12, 2012But I will always maintain that time, by itself, cannot be measured in and of itself without an inclusion of the speed of light or some other factor, as you have done in the formula. You can ask, "what is the speed of time?", or "what is the length of time?". But you must include with the question the thing that is relative or relevant to the question of time, such as in relation to a moving car or train, or the amount of time for a long distance runner to the finish line.
Time does exist, but to me the time is Adimensional and is measuring for tomorrow and today, but never the yesterday because that has already gone. Rather like an inchworm moving forward (tomorrow), then the front of worm remains in the present while it drags its rear up to the present also before moving forward again to the tomorrow (future).
Russkiycremepuff
1 / 5 (5) May 12, 2012And Adimensional time has always existed, along with the Adimensional space. The Adim Time is like the inchworm crawling across the Adim space in every direction simultaneously. If it encounters 3D anything, both space and time flow around the mass but not through it.

1 / 5 (5) May 12, 20121)always, when something moves or changes, i.e. the time is scalar quantity independent to the perceived order of events
2)only when we can recognize some order or causality in this motion, i.e. the time is vector quantity and it has always an "arrow" (no matter, how such arrow may be defined in this moment).
This decision is very substantial thing. For me only the second definition of time is correct, because if no causality exists in the motion or sequence of changes, than every random sampling of this sequence will not get to perceptible progress.
In dense aether model the Universe is random and full of motion like the gas, but it doesn't mean, some time runs there, as we cannot distinguish the direction of time arrow there. Such an universe simply is, but it doesn't exhibit neither time, neither space.
Terriva
1 / 5 (6) May 12, 2012The scalar definition of time has no connection to space-time and we cannot derive any new connection from it, because its noncausual by its very nature. If something moves or changes randomly, it would mean, the time may still flow in another dimensions, but not inside of our space-time. When such situation occurs, we can be sure, we are just confronted with extradimensions of our space-time.
Terriva
1 / 5 (5) May 12, 2012Because these forces and refraction phenomena are very common all around us, the observation of random time events from extradimensions is very common as well. The time runs in constrained systems only (like the water surface), the random events all around us are manifestation of time in extradimensions and they don't belong into 4D space-time slice, represented with energy spreading in vacuum.
Terriva
1 / 5 (5) May 12, 2012Now we can increase the refraction point of such gravitational lens, until it doesn't change into transparent glass sphere, floating freely at the flat 3D space-time. Such a glass sphere is not 3D object - but at least 4D object in AWT. It just means, the common glass sphere cannot be "just a 3D" object as well and we shouldn't apply the common 3D geometry for it. This perspective is required for the sake of consistency in further thinking. In AWT the curved space-time inside of massive objects forms a continuum with vacuum, everything is just a density fluctuation of it - only the density gradients are immense.

5 / 5 (1) May 12, 2012Terriva has also admitted that he can't do maths in previous posts. However, I think Pythagoras Theorem may be easy enough for you to grasp with a little effort.
Sorry but time is measured by any clock, a simple pendulum for example. The factor in the equation is the speed of light which is just a way of converting units, like degrees Celcius to Fahrenheit.
Events, like the deaths of Ceasar and Kennedy happen in different places at different times. It takes four values to locate an event, three for place and one four time. Mathematically, that makes it a dimension.
Fleetfoot

Correct. This particular maths is not too hard ;-)
A conversation when you get to a bus stop:
How far to the next town? - Ten miles.
How long until the next bus arrives? - Ten minutes.
Both questions are about separations, the first in space and the second in time. That's what the equations are about too. What people have found out from experiments is that space and time are not isolated, they must both appear in the complete, final equation.
Absolutely right, the universe shows only four dimensions to us, not six.

not rated yet May 12, 2012There are no extra dimensions in "AWT" because there is no such thing as "AWT". The only theory you have ever identified as "AWT" was actually Lorentz's aether theory, and it is 3D with ad hoc physical effects added to emulate SR, nothing more.
I'll repeat the same challenge I gave you each time we discussed this previously, show me where in Lodge's publication you can see any aether-related equation other than that of Lorentz. Just a page number would do but to date you have always failed.

1 / 5 (5) May 13, 2012Alright, since you say that the Time is 4th Dimensional, does it then have viscosity, opaqueness, turbulence, and capable of motion on its own? Can it be folded like a box or rolled into cylinder? Does Time hasten or slow down without benefit of Gravity and/or c and timepiece to display or record the movement? I agree that Adimensional Time does have length, only for present and future.

Russkiycremepuff
1 / 5 (5) May 13, 2012Yes, I agree with that part. It becomes the popular consensus among the physicists first; then the general population follow suit, as they will believe that the scientists know everything anyway.
But it is apparent that I did not include CMBR noise to remove along with earth, light, plane, clocks, etc.
My question is: as a stand alone quantity whose quantity or search thereof is frequently included in equations and measurements, what happens to that 4th dimensional Time outside of equations, Laws and experiments, etc. including removal of CMBR and all other radiations, matter and energies. Since it is said that in addition to 3 dimensions that are all discernible and are evident, where IS the 4th dimension of Time? Please do not tell me that the CMBR is Time, or that it is 4th dimension, because even CMBR had a beginning or genesis. Big Bang allows for 3D objects, 3Dimensions, directions, and distances.
Why do you suggest that length cannot have viscosity, etc If they are 3D?
Russkiycremepuff
1 / 5 (5) May 13, 2012But does a 4th dimensional Time also have viscosity, etc. as well as be discernible visually? Apparently not.
Terriva
1 / 5 (6) May 13, 2012The space is three-dimensional and it doesn't have a viscosity as well. It's just empty space with no other attributes or inertia. So why one-dimensional time should have some coligative properties? It's just additional compactified dimension of space - nothing less, nothing more. If you would travel into it, you will expand, if you'll travel from it into past, you will collapse. That's all.

5 / 5 (3) May 14, 2012Consider a block of jelly (US: "jello") on a plate. You place a ruler marked in cm on the top. One end of the jelly is next to the "3" mark while the other end is next to "8".
The numbers "3" and "8" are coordinates and the amount by which they are separated is the length of 5cm.
The jelly certainly has viscosity but the numbers we use to measure how ong it is do not. It is the numbers and their possible range which are related to there being a spatial dimension. Viscosity and all the other physical properties you list apply to the object, not to "length".
What I would suggest is that as a minimum you need to learn enough maths to understand the definition of a dimension before telling mathematicians they have go it wrong.
Russkiycremepuff
1 / 5 (5) May 14, 2012You have partially misinterpreted my meaning, although you are correct that I should be more specific and thorough. I am not saying that Time does not exist. It certainly does and is everywhere in the universe. But, my argument is similar to Amrit Sorli's in that Time is not residing in a fourth dimension at all and is absurd to include T as "fourth dimensional" means of measurement in any equation. An equation to include Time to measure c is valid, of course, as well as all three dimensions; but Time in and of itself without everything else, is quite "Adimensional". The Adimensionality of Time indicates that Time has always existed, even before the Big Bang, along with Adimensional Space. Long before the genesis of matter and energy exploded out of the "Singularity" that was the Big Bang and spread out into the Adimensional Space that was OUTSIDE of BB, Time (also outside of BB) was everywhere already and was Adimensional due to it not being a 3Dimension medium of measurement

You can see busses arrive at a bus stop and see that one arrives after the other, the arrivals are separated in time, but to measure the length of time between them, you need a clock. Time is as much a dimension as those of space, it serves the same purpose to separate events like a bus arriving in the same way that space separates the dots on the paper.
Russkiycremepuff
1 / 5 (5) May 14, 2012Extra-Dimensions over and above the first three are stuff of science fiction. If you said that you know of a seventh dimension, I and everyone else must inquire as to its location and the evidence of it, especially if you wish to have a seventh dimension included in math equations. Time has been elevated as fourth dimensional, but seems that no one can fully explain fourth dimension itself as to location, properties, visibility, characteristics, evidence of existence, etc.
Whereas, the three dimensions occur everywhere you look. But Time, as Adimensional, is logical and does not beg for explanation as to its visibility, location, etc. AdimensionalTime just is, and that is all explanation needed. Adimensional Time is necessary, of course, but it only measures 3D with distance and direction of 3D objects, length of events, etc. If Time were a fourth dimension, it would be impossible to travel to it and live in it, whereas, we do live in height, width and depth of 3 dimensions.
Russkiycremepuff
1 / 5 (5) May 14, 2012I had said much earlier that Adimensional Time only measured the future and the present, as going forward to future and bringing it to make the future become the present in a measured way. The AdimTime is the same everywhere, except for the measuring of sunrise and sunsets in all parts of universe where there is 3D matter, energy, Forces, etc., which are measured by 3D instruments that are meant for such purposes.
That Adimensionality of Time existed always because there was, and is, always a future and a present; very basic. But, I find that I must revise the purpose of AdimensionalTime to include the measuring of the 3D matter, energies, and all that exploded out of BB, as there is no 4th dimensional Time. As there cannot be two kinds of Time, it is only the Adimensional Time that can be also measuring the 3Ds. In this way, there is unification and no ambiguity. There is no actual evidence of 4th dimension, but only in minds of those who required it for equations.

- Fleetfoot -
You have said it yourself, "the arrivals are separated in time, but to measure the length of time between them, YOU NEED A CLOCK" It is that clock that is doing the measuring; the seconds and minutes painted on it are separated ON THE CLOCK FACE by lines as intervals that only represent the Time passing. The clock is mechanical method of marking the passing time.
Russkiycremepuff
1 / 5 (5) May 14, 2012The Time itself is only perceived volume arbitrarily arrived at by observation over centuries of sunset and sunrise, seasons, tides as influenced by the moon, earth orbit and tilt, and some other factors. But the 4th dimension does not reside in the clock. It is the gears and wheels, etc. that are driving the seconds, minutes and hour hands, and Time itself is not driving those hands to move; only the gears and wheels, etc. do that. Often there is a lever on clocks that can make it run slower or faster.
Time as 4th dimension cannot exist as a 4th dimension because of essential need for mechanical 3D objects: a timepiece, ruler or yardstick, tape measure, odometer, altimeter, thermometer, spectrometer, etc. These are all manmade instruments designed to measure what is being measured against the lines on the clock face and the clock's mechanism. It is all mechanical.

not rated yet May 14, 2012Exactly, just as the odometer in your car is a mechanical method of marking the passing of distance. There is nothing complex about this at all.
Fleetfoot
5 / 5 (2) May 14, 2012No dimension "resides" anywhere, objects "reside" at certain locations and over some distance. They exist at certain times or for some duration.
Trying to keep this as non-mathematical as I can, the range of numbers which can be used to describe a location or a time is what is meant by a "dimension".
Take a trivial example. Suppose I drive to the other end of town, a distance of 4km at a speed of 40km per hour. I can calculate it will take 1/10 hour or 6 minutes.
The equation I use is: duration = distance / speed
If I depart at 9:15, I will arrive at 9:21.
The equation is: arrival_time = departure_time plus duration
You want to say that time is not a dimension, well in that case I am not allowed to use times as coordinates or their difference as a separation called "duration". Both the above equations become invalid, so what are you proposing we should replace them with? What is your alternative?
Russkiycremepuff
1 / 5 (5) May 14, 2012AdimensionalTime and Space are passive. They allow all the work to be done by 3Dimensional objects, matter, energies, EM, DM, DE, gravity, events, etc. These are the workhorses of the universe.
Russkiycremepuff
1 / 5 (5) May 14, 2012I have already said that Time is "Adimensional", meaning that AdimTime is without dimension, similar to Atheists being "without G-d". Not having dimension does not mean nonexistence. It exists, but is more ethereal and has no form and no particular place. In equations, there is no indication that Time has form, none at all. In equations, Time is only a commodity by which everything is measured. The math is also ethereal and can be changed and is a product of mind to formulate a method.

5 / 5 (1) May 15, 2012We haven't spoken before so I can't say. I think we have identified one word that can be improved though ;-)
Exactly. That is what the word "dimension" means.
I now understand why there has been a disagreement. "Dimension" does not mean a place, it means the numbers used to say where the place is or when an event happens. Here is a page about it which is probably more complex than is needed here but there is a particular sentence that you may find informative:
"Whereas outside of mathematics the use of the term 'dimension' is as in: 'A tesseract has four dimensions', mathematicians usually express this as: 'The tesseract has dimension 4'."
