Bringing balance to the universe: New theory could explain missing 95 percent of the cosmos

Scientists at the University of Oxford may have solved one of the biggest questions in modern physics, with a new paper unifying dark matter and dark energy into a single phenomenon: a fluid which possesses 'negative mass." If you were to push a negative mass, it would accelerate towards you. This astonishing new theory may also prove right a prediction that Einstein made 100 years ago.

Our current, widely recognised model of the Universe, called LambdaCDM, tells us nothing about what dark and dark are like physically. We only know about them because of the gravitational effects they have on other, observable matter.

This , published today in Astronomy and Astrophysics, by Dr. Jamie Farnes from the Oxford e-Research Centre, Department of Engineering Science, offers a new explanation. Dr. Farnes says: "We now think that both dark matter and dark energy can be unified into a fluid which possesses a type of 'negative gravity," repelling all other material around them. Although this matter is peculiar to us, it suggests that our cosmos is symmetrical in both positive and negative qualities."

The existence of negative matter had previously been ruled out as it was thought this material would become less dense as the Universe expands, which runs contrary to our observations that show dark energy does not thin out over time. However, Dr. Farnes' research applies a 'creation tensor," which allows for negative masses to be continuously created. It demonstrates that when more and more negative masses are continually bursting into existence, this negative mass fluid does not dilute during the expansion of the cosmos. In fact, the fluid appears to be identical to dark energy.

Dr. Farnes's theory also provides the first correct predictions of the behaviour of dark matter halos. Most galaxies are rotating so rapidly they should be tearing themselves apart, which suggests that an invisible 'halo' of dark matter must be holding them together. The new research published today features a computer simulation of the properties of negative mass, which predicts the formation of dark matter halos just like the ones inferred by observations using modern radio telescopes.

Albert Einstein provided the first hint of the dark universe exactly 100 years ago, when he discovered a parameter in his equations known as the 'cosmological constant," which we now know to be synonymous with dark energy. Einstein famously called the cosmological constant his 'biggest blunder," although modern astrophysical observations prove that it is a real phenomenon. In notes dating back to 1918, Einstein described his cosmological constant, writing that 'a modification of the theory is required such that "empty space" takes the role of gravitating negative masses which are distributed all over the interstellar space." It is therefore possible that Einstein himself predicted a negative-mass-filled universe.

Dr. Farnes says: "Previous approaches to combining dark energy and dark matter have attempted to modify Einstein's theory of general relativity, which has turned out to be incredibly challenging. This new approach takes two old ideas that are known to be compatible with Einstein's theory—negative masses and matter creation—and combines them together.

"The outcome seems rather beautiful: dark energy and dark matter can be unified into a single substance, with both effects being simply explainable as positive mass matter surfing on a sea of negative masses."

Proof of Dr. Farnes's will come from tests performed with a cutting-edge radio telescope known as the Square Kilometre Array (SKA), an international endeavour to build the world's largest telescope in which the University of Oxford is collaborating.

Dr. Farnes adds: "There are still many theoretical issues and computational simulations to work through, and LambdaCDM has a nearly 30 year head start, but I'm looking forward to seeing whether this new extended version of LambdaCDM can accurately match other observational evidence of our cosmology. If real, it would suggest that the missing 95% of the cosmos had an aesthetic solution: we had forgotten to include a simple minus sign."

This is a really nice paper (very easy to understand, although HIGHLY speculative, of course).

Link here; https://arxiv.org...12.07962

The usual trivial problems:
- This is not the cosmology we live in. It makes a bouncing universe with the wrong topology (AdS instead of approximately dS) and a time varying Hubble constant in the current era.
- This is not the physics we live in. It has creation of particles out of nothing (shades of Hoyle's static universe), and suggest "negative mass" while gravity is unipolar.
- This is insufficient in competition with LCDM. It is explaining a fraction of the dark matter/dark energy effects. So no prediction of seeing the DM peak in the CMB spectra (instead it notes that new phenomena should be seen - why?) or DM lensing.

Nothing to see here; moving on.

Yeah. (Seems to be popular, too...I'm having a hard time downloading it).
My initial reaction is: what about (energy) conservation laws? Doesn't that contradict a creation tensor? But maybe once I get it that will be explained.

On the upside: If there is indeed negative mass (and it can be contained and/or manufactured) then an Alcubierre type warp drive might actually be feasible.

I've thought for a long time that there can be no "nothing"; and that black 'holes' are just this clear stuff roiling around and sometimes acting like water draining, or a tornado, not sure about the negativity of it, however I believe it's involved in the perception of gravity. It's gravity I'm not so sure exists as it's described. I think Gravity is the pressure of this stuff, rather than some attractive quality of mass. If planets are the grapes, dark matter is the jello. Only total ignorance can produce theories like mine; Sometimes it's good to start fresh. By the way, is the temperature of a mass thought to affect its gravity?

once it is understood that our common sense notions of space and matter are inverted - it will all fall in
place - space is the reality - matter the phantom. . matter is but a local disrupttion of space. Space is probably colaspsing at half the speed of light while the phantom matter appears to expand. Space synchronizes everything and its behavior is what creates time. Time is a property of the behavior of space.

We made up dark matter and dark energy and have never found a single particle or erg of either.

Now we expect to trade our magic matter and energy for a magic fluid which has negative mass, negative gravity and which, when pushed, pushes back.

When may we expect floating airplanes and rockets which need hardly any push to reach escape velocity?

At least they got the repulsion part correct...baby steps in the right direction. Too bad about the mathematical requirement for anything other than a field. Negative fluid matter....LMAO.

"with both effects being simply explainable as positive mass matter surfing on a sea of negative masses"

This is hilarious to anyone who actually works with magnetic fields. Add the word "charge" before mass and replace the masses with fields...as close as the above can get to reality.

Dr. Farnes says: "We now think that both dark matter and dark energy can be unified into a fluid which possesses a type of 'negative gravity," repelling all other material around them.

....because the fact that pretty much all matter in space carries a charge is irrelevant to any kind of repulsion phenomenon. Yeah...that's it.

Responding to the forthcoming barrage from the usual suspects....now we have repulsion in the equation...bye bye gravity math, hello new gravity math...it's a start.

Actually, in 1955 Einstein wrote a book in which he expressed his understanding of the applicable physics at that time, "There can be no energy without a field to bind it". It took the smartest man to live in the 20th century 37 years to figure it out and say it after his 1918 musing mentioned above. Farnes working off what Einstein said in 1918...must have got the advice from Jones....

This is the difference between understanding "physics" and understanding math...therefore thinking you understand physics. I stated a repulsive force was necessary to explain galactic motion. Not one single mainstreamer agreed because the math didn't say it...had a heated exchange with a psycho and a couple of psychos in training. Now here we are with "This astonishing new theory ".....that attraction is not the only "force" governing motion. It is only new to mainstream dogma, hence why suggesting it was received the way it was. So it is nice to see Mainstream theoretical guys taking the first steps to catch up to those who have already recognized this. Too bad their followers still appear to be stuck in the mud....

Um, cosmos, as in cosmology, so spacetime expansion; but also the spacetime geometry of general relativity where light is red-shifted climbing out of a gravity well, and also that light would curve away from dark energy regions (and dark matter?) rather than curving around them-- it's not like dark energy and dark matter are the only criteria that have to be satisfied...

Um...so far, we can only manipulate light with a magnetic/electric field. And our only verified physical effect on photons is polarization...again, magnetic field. All other optical effects attributed to "bent spacetime" due to "gravity wells" A) occur in the presence of magnetic fields and B) cannot be verified. Unless you can reference any instance where we experimentally "bent spacetime". You are correct how light "could" behave if the negative gravity fluid was viable, it doesn't. I am just agreeing with the repulsive force modelling as it is blatantly correct, but not due to "negative gravity". As I said they took a baby step in the right direction, now they are standing still facing the right way...they just need a telescope to see how far behind they are.

It seems that I have some trouble with the basics here.
If negative mass is when something, pulled by gravity accelerates in a direction opposite to the direction to the center of the pull /accelerating in a direction opposite to the gradient of the increasing of the field/, but pushed by /the proposed/ antigravity would accelerate towards the "center" /moving in the direction of increasing field gradient/... and if most of the matter, being dark matter, is with negative mass, and predominant field, permeating the Universe is that of antygravity... wouldn't that actually result in a contracting, instead of expanding universe?
And how about the property of actually being "dark"? I mean - nothing in seems to explain why this negative mass matter is completely indifferent to electromagnetism /note that it does not create "antilight" as may properly be expected from "negative energy matter"/.

Our visible universe is in the outflow of a super-supermassive black hole. As ordinary matter falls toward the super-supermassive black hole it evaporates into dark matter. It is the dark matter outflow which pushes the galaxy clusters, causing them to move outward and away from us. The dark matter outflow is dark energy.

The galaxy clusters which have been pushed for longer than we have are accelerating outward and away from us. We are accelerating outward and away from the galaxy clusters which have been pushed for less time than we have. From our perspective most of the galaxy clusters are accelerating away from us.

Here's an easy way: find a mirror image of any galaxy. Sort of like the opposite of an Einstein ring, with the galaxy adjacent (as it appears in the sky) to a region of dark energy but much farther away than that region... finding such a mirror image (even distorted) would support their notion.

Asymmetrical.

Very very slightly asymmetrical.

137, or...0.00729927007299270072992700729927

and thus, unidirectional time, gravity, mass, etc.

With big ass (seeming) energy available on breakdown.

It's not really, it's just separated or torn from the backdrop support structure of the given dimensional bubble.

Like the speed of light, not really a limit but a limit in and of the dimensional bubble.

And when the thing is seen as the bubble of resonance that it is (infinity boundaries on both ends), then you can see enough of the shape of it to curve fit the quantum into the scenario.

One can use the mathematics if they wish but that is not the fundamental, the point of understanding is the fundamental.

Oh Boy! A new, imaginatively constructed speculation for all of us to argue over.

The question I have is. If the DM/DE combo produce "Negative" Gravity?

Why are the larger galaxies, in general, spiral shaped? Wouldn't the effect of NG from a surrounding sphere of DM pushing the on the structures from all directions, result in spherical galaxies?

And, as t_b_g_l asked. Where is the DM lensing effect?

Other questions I have are. If NG is a product of DM & DE? Centered (anchored?) around galaxies? How could there be any inter-galactic mass, such as gas streamers to be observed?

Many galaxies outer arms consist of extensive gas & dust clouds. Wouldn't the NG have rudely shoved all that low-mass debris deep into the cores of the larger galaxies?

And how would it be even possible for the ancient, low-mass dwarf galaxies to exist as satellites of the larger galaxies?

The creation tensor is equivalent to the creation operator in the standard model of particle physics ( https://en.wikipe...rd_Model ) when one tries to unify the SM with general relativity.

As an important aspect of quantum mechanics, this "magic" is therefore an integral part of the theory that made possible the very technology you are using to make your posts..

So, what is your definition of magic?

Is it magic if it can be clearly seen to work?

One area the paper does not cover, as others have noted, is gravitational lensing. This idea is incomplete without addressing this. While lensing studies are invoked, the actual lensing observed is not addressed.

It's an interesting toy model. But I'll wait to see what the general astrophysics and relativity communities have to say.

If it has negative gravitational mass it should accelerate exactly opposite way until it reach velocity-> c and in result we should have 2 separate universes one with positive mass and one with negative. If it has only negative kinetic mass then it should resist any movement in space

On the other hand, time is not an intrinsic property of a reference frame, because our orbiting satellites experience time changes due to grav induced frame dragging by the earth's mass in proximity. This should mean the affected satellites would be out of our reference frame and become invisible to us like the scenes in the movie 'Langoliers'...like almost in another dimension. But because we CAN send time sync signals TO those sats AND recieve data FROM those satellites means that radio can cross time barriers.....but how? It is in a small scale like we could talk to intelligent dinos, Troodons, if they ever existed, over a gap of eons of time. In for a penny then in for a pound. Thought experiment that maybe says that frame dragging is flawed.

Thanks pepe, for correcting my assumption. But still? My question still applies, even for elliptical galaxies. Why hasn't the DM/DE combo NG not pressed them into spheres?

Plus, as with spirals, elliptical galaxies have streamers of gas & dust flowing outbound,
In addition to satellite dwarf galaxies?

& how many of those ellipticals are actually spiral galaxies observed from an inconvenient POV?

Especially since many of the larger galaxies, both spiral & elliptical are mergers through collisions & cannibalizing their neighbors.

A future example is the passionately torrid, flamboyant dancing predicted between our Milky Way & the Andromeda Galaxy.

How would that event be possible? Or any other collisions & mergers between Cosmic bodies?

Wouldn't the speculated DM/DE Negative Gravity effect prevent any of those occurring?

Good new theory should not only predict already observed things, but should predict something new, unknown until now.

Having reviewed the papers a few times each, I find this plausible but not compelling. One major mark against it is that the author doesn't seem to realize that negative mass popping out of nowhere violates conservation of mass/energy- which need not only be for positive, but also for (putative) negative mass as well. It's a bold hypothesis, and well supported, but it has at least two problems (both unacknowledged by its creator) that seem fatal unless some explanation can be discovered: violation of mass/energy conservation and gravitational lensing. We'll see if the author or others can clear these up, and what other defects I might have missed might be advanced by the cosmology and relativity communities.

I think gravity reverses and becomes repulsive at approximately 1.5 million light years. It becomes more and more strongly repulsive, reaches a peak, and then decreases trailing off to zero.

This does away both with dark matter and also dark energy. It explains why most galaxies are accelerating away from each other.

It also explains gravitational rotational rates. Galaxies are pushing against each other keeping outer stars in a faster than expected orbit. You may read the justification for this theory here, along with responses to objections at the bottom:
https://www.reddi...tter_is/
General Relativity must be adjusted such that we keep time dilation, BUT ditch curved or dilated space. I.e. we should work with flat, 3D , Euclidean space + time dilation. I explain about this in the notes at the bottom of the article.

If the proposed "fluid" projecting a "negative gravity" exists throughout the entirety of space/time, then the negative gravity fluid halo surrounding a galaxy would be largely or totally countered by the negative gravity fluid that logically would also extend throughout the interior of the galaxy-- therefore the galaxy would still not exhibit the gravitational cohesion we observe. Eliminating the repelling fluid from the interior of galaxies would seem to be a mathematical gambit to force a somewhat workable cosmological theory. Although we need new thinking on this subject, this almost-universal repelling "fluid" seems like a lot to swallow.

According to Feynman lectures from 1960's the counterpart of gravitational energy of total mass M in 3-D space is its rest energy MC^2. This energy balance at BB was extended to one simple 'energy balance field equation' by Dr. Suntola in books, papers and annual seminars since 1995 by correcting a series of GR/QM flaws. This enabled his Dynamic Universe system to become valid for unbiased cosmic modeling while agreeing also with GR/QM predictions in locally validated systems within 18 decimals. The 1998 SN1a data of intergalactic distances could be explained as well or better than the flawed GR based standard model - without any auxiliary 'epicycle' parameters such as DE/DM densities of cosmological constant. The unnecessary 'negative mass' idea is today an epicycle correction to the Nobel rewarded DE epicycle - in hopes of additional Nobel mistakes in recent years!?

To be entirely fair, he develops various scenarios into possible explanations but ends not only by saying he didn't really consider them and they're follow-up work, but by reiterating his statement that it's not really necessary. It would appear you have found another defect in the paper. Well done sir.

Now, all of these defects may disappear; but if a bunch of folks on a relatively obscure Internet site can spot this many, how many will expert astrophysicists and relativists spot? I'd watch Sabine Hossenfelder's site, Backreaction. If she posts something I will try to remember to link it here.
Ojorf
3.8 / 5 (5) Dec 06, 2018
The part of section 4.2, where he takes the local universe to be flat and considers the effect of negative masses on the location of the CMB peaks.
He says in a negative mass universe at z=1100 an astrophysical object would have an observed angular size 169 times less than in LCDM. (Eq 30)
He then carries on, calculates the sound horizon and just after Eq 33, concludes that instead of a discrepancy of a factor of 169 there is substantial cancellation between the larger geometrical term and the larger sound horizon, so that within a factor of approximately 2 it predicts the location of the first CMB peak and my be consistent with observations.

What about this idea which is related to this discussion thread. I have changed the dark matter/energy/fluid to the word "medium" to mean unknown "material" as I think it is more appropriate to what I am going to say.

If you take the Universe as being full of matter and this medium (dark energy/matter) my idea is that the medium would be required in order to transfer field information. How could you possibly transfer gravitons or photons if there was no medium in which to transfer that information. It must be a way of exchanging information. For matter to work with gravity and EM field information the rest of the Universe must be a medium in which to transfer that information. That medium must be at a constant "viscosity" otherwise there would be patches where no field information could be transferred. That means that as the Universe expands there must be enough of that medium coming into the Universe to fill the gap that is left as the Universe expands.
(1/3)
richard_k
3 / 5 (2) Dec 07, 2018
The Universe must have an edge to it as there is no medium there for the field information to be transferred. Also as the medium and matter do not occupy the same space; then as this medium is "pumped" into the Universe it must force the matter further outwards at the rate of expansion of the pressure of that medium being pumped into the Universe. And as the Universe gets bigger the outer edge is always expanding meaning that in order to maintain the viscosity of the medium the size of the medium entering the Universe is directly proportional to the size of the edge of the Universe. What is controlling the force of that pressure is unknown but that is what is controlling the rate at which the Universe is expanding. That medium must be everywhere including in our solar system and obviously as soon as matter moves the medium must fill its place. Without the pressure of the medium the gaps would not be filled as matter moved.
(2/3)
richard_k
3 / 5 (2) Dec 07, 2018
However as matter moves inside the Universe due to gravitation and centrifugal forces the pressure of the medium would have some effect on the speed and direction of the clumps of matter moving through the Universe.

Strange thought, but if the medium being forced into the Universe like a tap flooding a balloon with liquid what happens when the tap is turned off.

You make this claim without any evidence. Where is your evidence? Why would any medium be required? If I shoot a gun, is a medium required for the bullet to travel through the air and hit its target? In the case of a bullet, any medium only inhibits the bullet's travel.

So I used the base of a wine glass as you would to illustrate the spacetime curvature of a gravitational lens but I inverted it to show that there's a mirror image with an adjacent-in-the-sky alignment. There are actually three distinct (tho distorted) mirror images. This is an experiment that's fairly safe to try at home. I tried to find a mirror image using the base of the glass normally, as with a standard gravitational lens, and couldn't find one. I uploaded a picture where I used a "sample galaxy" with a center that has a good asymmetry in shape and color to highlight the mirroring aspect of spacetime curved in the opposite direction of normal, "positive" gravity: Illustration of Anti-gravitational Lens

Hi zz5555,

Thank you for your comments regarding my post.

I just take a passing interest in these things. It was an idea that popped into my head after reading this article, I make no claim or have no evidence (that would take too much time) and I accept it could be a stupid idea. I just threw it out onto this forum as it seemed a simple idea/explanation for people to ponder.

We only think the Universe works the way it should because that is all we know. But the non-locality of variables (i.e. entanglement) is not consistent with the world we experience. There is no god given reason why absolutely everything in the Universe must match our daily experience.

Thank you for posting a link to Sabine's blog. It has been an interesting read.

As with all these things you can only prove your theory is right if your model simulates and matches all the known data and the world we experience. Only time will tell who was right and who was wrong.

In your gun example, it is the "air" in which the bullet is traveling that is the 'medium'. There are other factors, such as friction, wind velocity, weight of the bullet, etc. that could affect the flight of that bullet.
The same is true for a submarine firing off a torpedo where the medium is water. One could also say that the torpedo and the bullet are the "information" or "message".
