A new theory of gravity might explain the curious motions of stars in galaxies. Emergent gravity, as the new theory is called, predicts the exact same deviation of motions that is usually explained by invoking dark matter. Prof. Erik Verlinde, renowned expert in string theory at the University of Amsterdam and the Delta Institute for Theoretical Physics, published a new research paper today in which he expands his groundbreaking views on the nature of gravity.
In 2010, Erik Verlinde surprised the world with a completely new theory of gravity. According to Verlinde, gravity is not a fundamental force of nature, but an emergent phenomenon. In the same way that temperature arises from the movement of microscopic particles, gravity emerges from the changes of fundamental bits of information, stored in the very structure of spacetime.
Newton's law from information
In his 2010 article (On the origin of gravity and the laws of Newton), Verlinde showed how Newton's famous second law, which describes how apples fall from trees and satellites stay in orbit, can be derived from these underlying microscopic building blocks. Extending his previous work and work done by others, Verlinde now shows how to understand the curious behaviour of stars in galaxies without adding the puzzling dark matter.
The outer regions of galaxies, like our own Milky Way, rotate much faster around the centre than can be accounted for by the quantity of ordinary matter like stars, planets and interstellar gasses. Something else has to produce the required amount of gravitational force, so physicists proposed the existence of dark matter. Dark matter seems to dominate our universe, comprising more than 80 percent of all matter. Hitherto, the alleged dark matter particles have never been observed, despite many efforts to detect them.
No need for dark matter
According to Erik Verlinde, there is no need to add a mysterious dark matter particle to the theory. In a new paper, which appeared today on the ArXiv preprint server, Verlinde shows how his theory of gravity accurately predicts the velocities by which the stars rotate around the center of the Milky Way, as well as the motion of stars inside other galaxies.
"We have evidence that this new view of gravity actually agrees with the observations, " says Verlinde. "At large scales, it seems, gravity just doesn't behave the way Einstein's theory predicts."
At first glance, Verlinde's theory presents features similar to modified theories of gravity like MOND (modified Newtonian Dynamics, Mordehai Milgrom (1983)). However, where MOND tunes the theory to match the observations, Verlinde's theory starts from first principles. "A totally different starting point," according to Verlinde.
Adapting the holographic principle
One of the ingredients in Verlinde's theory is an adaptation of the holographic principle, introduced by his tutor Gerard 't Hooft (Nobel Prize 1999, Utrecht University) and Leonard Susskind (Stanford University). According to the holographic principle, all the information in the entire universe can be described on a giant imaginary sphere around it. Verlinde now shows that this idea is not quite correct—part of the information in our universe is contained in space itself.
This extra information is required to describe that other dark component of the universe: Dark energy, which is believed to be responsible for the accelerated expansion of the universe. Investigating the effects of this additional information on ordinary matter, Verlinde comes to a stunning conclusion. Whereas ordinary gravity can be encoded using the information on the imaginary sphere around the universe, as he showed in his 2010 work, the result of the additional information in the bulk of space is a force that nicely matches that attributed to dark matter.
On the brink of a scientific revolution
Gravity is in dire need of new approaches like the one by Verlinde, since it doesn't combine well with quantum physics. Both theories, crown jewels of 20th century physics, cannot be true at the same time. The problems arise in extreme conditions: near black holes, or during the Big Bang. Verlinde says, "Many theoretical physicists like me are working on a revision of the theory, and some major advancements have been made. We might be standing on the brink of a new scientific revolution that will radically change our views on the very nature of space, time and gravity."

Guys. Dark matter isn't necessarily matter. Stop taking this so literally. Dark matter is a placeholder term for something that *behaves* like matter. If the theory of Verlinde pans out then his theory will be 'dark matter' (though it'll likely get another name).

While correct in stating that dark matter is a blanket term covering observed gravitational effects, those effects are matter specific. MOND is an example of an ALTERNATIVE to dark matter theory, it involves modifying the gravitational laws to better fit observations vs invoking invisible dark matter halos.

If you mean normal disc rotation as in a stellar accretion disk or in an evolved solar system the planetary orbits (ours anyways), the angular momentum appears to adhere to the inverse square law for bodies as you move away from the central gravitational mass, in a spiral or barred galaxy, the bodies do not. The observed discrepancy is what led to the proposal of DM in the first place. All equations of mass/orbital motion around a central body were derived based on observations of how bodies move in our solar system, the bold statement that it must work this way for the entire universe was a little premature.

I have been saying this for many years, only to be met with derision by so-called mainstream scientists. However, Verlinde hasn't got it quite right, its not the "fundamental bits of information", its the positions of the elemental constituents of matter themselves. Imaginary spheres with information and information stored in "space itself" are unnecessary inventions. What next? A "space-time continuum with dimples in it"? Forget gravity and look at the rotation of galaxies under expansion theory - it fits.
Reg Mundy
Well, LIGO measured something, but was it gravity waves? I suggest they measured perturbations in TIME, which is known to be subjective.
liquidspacetime
Curved spacetime is the state of displacement of the superfluid dark matter.
The geometrical representation of gravity as curved spacetime physically exists in nature as the state of displacement of the superfluid dark matter.
The superfluid dark matter displaced by the Earth pushing back and exerting pressure toward the Earth is gravity.
The state of displacement of the superfluid dark matter is gravity.
tblakely1357
Urgelt
They measured perturbations in spacetime.
Spacetime can be measured. In fact, very precise measurement of spacetime was necessary for LIGO to work in the first place.
You're taking away the wrong impression from Special Relativity. The rate of time passing relative to a different observer can vary based on velocity differences of the two observers; but that does not mean time is wishy-washy, unmeasurable, indistinct, or alterable by your beliefs or opinions. And it does not invalidate LIGO's detections.

Hopefully this will lead to a better understanding of the nature of gravity caused by the presence of visible matter.
Seeker2
Visible matter presumably blocking out or displacing the bits of information of spacetime leading to a gradient in the density of these bits in spacetime and hence the rate of expansion of spacetime.
Seeker2
This gradient in density leading to less expansion in regions of visible matter. Meaning we are getting squeezed out (eventually into black holes) by a lack of back pressure to counter this expansion.

What are you, the Donald Trump of physics?
'Dark Matter' is a placeholder term. Nobody knows what causes cosmological observations of motion to defy the conventional understanding of gravity. WIMPS are a class of possible explanations, but not the only class of possible explanations, for Dark Matter. There's no reason to prefer WIMPS over other explanations because there's no direct evidence for them, or any other explanation, right now.
The point of this article is to show that at least one theory other than WIMPs for Dark Matter is in circulation among physicists. If you comprehended the article, you would grasp that your summary for Dark Matter is utterly bogus.
Reg Mundy
Do not put your words in my mouth. I did not say the results from LIGO were invalid. I said that what they measured was a perturbation in TIME. I did not say space/time, which is a mathematical concept. I merely point out that the measurements did not necessarily show gravity waves, there are other explanations.

Oh dear, have you looked at the shape of the LIGO signal? How does that particular shape rule out time distortion and endorse gravity waves? There is still no sign of the very-necessary gravitinos required to substantiate gravity waves, yet you hold their existence to be carved in stone on tablets handed down by whoever is your god.

"...have you looked at the shape of the LIGO signal? How does that particular shape rule out time distortion and endorse gravity waves?"
You still don't get it. They're measuring a transient distortion of spacetime. It's a wave.

I don't get it? You obviously misinterpret what I have said, and I don't get it? Its you who "don't get it", brother. Did you notice that I said "a perturbation in TIME"? You persist in talking about spacetime as if it is real, whereas it is patently a mathematical concept that has no basis in reality. There is space. There is time. They are separate things, unless you agree with me that time itself is a function of the position of elemental particles? In which case, time is subjective and only exists in our experience as a side effect of the positions of the elemental particles. LIGO measured a change in position of matter using lasers (i.e. light), the velocity of which is totally dependent on the rate of change of "time".
tbc
Reg Mundy
(contd.)
Thus, a perturbation in time will manifest as a change in the length of the LIGO pathways as measured by a laser. Whats all this crap about a "wave in spacetime"? Its a wave in space caused by our perception of positions assuming time is constant, which it ain't.
Urgelt
Crankery at its finest. Reg is certain that if he strings together words just so, he has mastered physics in a way that mere mathematical physicists can never do.

Reg Mundy
The ONLY means we have of measuring the passage of TIME is by the positions of matter. Thus, rate of change of TIME is defined by rate of change of position of matter. Therefore, as far as we are concerned, TIME is merely a side effect of the apparent movement of elemental particles. You would have to read https://www.amazo...+gravity (free on Kindle) to understand why I think this is so. The quantum nature of TIME itself provides the phenomenon we perceive as gravity.
Reg Mundy

Spacetime is a concept which mixes apples and pairs. Space is measurable in three dimensions, time is something which moves forward at a constant rate (to us, subjectively). Mixing the two together to make "spacetime" is a meaningless exercise in reality and only useful as a mathemetical concept for performing mathematical functions (similar to the squareroot of minus 1, for example). Its a bit like Einstein's spacetime continuum with dimples in it caused by mass which causes the effect of gravity. Useful as a visualisation, but nevertheless an invention with no basis in reality, only imagination.
ScienceIsHard
I think it's fair to be critical of the entropic gravity theory here. The headline-grabbing proposition of the paper is something the author acknowledges is an interesting numerical coincidence rather than a well-founded model of the structure of the universe. If it's really possible to explain what we think is a fundamental force in the math of string theory, and explain real-world phenomena like dark matter, it still doesn't mean string theory is right. But it would finally leap from a theoretical model to an applicable model. And if anyone can manage that, they will get a Nobel prize.
I also think it's fair to say there are plenty of scientists who are skeptical that String Theorists or Relativity deniers have Nobel Prizes in their future.

Look, science is NOT hard for me in spite of how hard it may be for you, I spent 6 years in Engineering school studying Nuclear/Electrical Engineering & found my studies may have been challenging, but not hard.

Zwicky was never been able to pull it off, but you know how?

Part III: Considerations on the Universe as a Whole
Albert Einstein 97
If we are to have in the universe an average density of matter which differs from zero, however small may be that difference, then the universe cannot be quasi-Euclidean. On the contrary, the results of calculation indicate that if matter be distributed uniformly, the universe would necessarily be spherical (or elliptical). Since in reality the detailed distribution of matter is not uniform, the real universe will deviate in individual parts from the spherical, i.e. the universe will be quasi-spherical. But it will be necessarily finite. In fact, the theory supplies us with a simple connection between the space-expanse of the universe and the average density of matter in it.
Ultron
@antialias
No, that is not true. GPS is running without any reliance on some GR based correction calculations. The time is simply updated from one central point on all satellites. So it could be running without any GR knowledge at all. On the other hand the corrections differences could be used for confirmation of GR, but this is not what you are claiming.

Special Relativity does have problems too. I recently explained that a new equation of mass-energy equivalence is necessary to account for the difference in E and mc^2 from the 2005. experiment. With the new equation I also explained the fine structure constant value.

The most dubious thing about this statement is that everyone I've ever met that does science finds it infuriatingly difficult to add to the collective knowledge. You have to find a gap that hasn't been explored and do something meaningful in it, and have it matter enough to get read by other people and absorbed into their work. How many discoveries do scientists make over their careers that meet that bar?
On the other hand, you do have some people that can have many in a single year. With your background, H-mode fusion should be a reasonable match. There are 10's of thousands of papers on it, yet it's not figured out. I'm being serious, too... if you think this is easy... your talents are wasted on whatever you are doing now.

Without knowledge we give existence a sacred spot in our reality. However, if we are simply a stable set of these spherical fields;if you think long enough, you will see we are nothing but a state, not a thing, non existence and existence is only motion and updates of these.

RealityCheck
We've been through your dishonest/uninformed/personal subjective 'versions of reality' before, CS. You have already seen many of my posts/explanations; you and Ira even referred to them a few times. Yet you deny it all?
Did you ask IMP-9, other interlocutors, to whom I pointed out many FLAWS in BB/Inflation/Expansion and standard-candle/distance-ladder assumptions/methodologies etc etc etc now increasingly being found also by mainstreamer recent discovery/reviews?
That Prof Paul Steinhardt video I LINKED corroborates much of what I have said for YEARS re seriously flawed "Inflation" hypothesis/assumptions/interpretations being "passed by peer review" and so building-in said FLAWS into the literature/exercises involving/based on said flawed "Inflation" etc assumptions/claims?
So, CS, can you pause your personal/irrelevant rants long enough to ADDRESS Prof Steinhardt's on-SCIENCE point re "INFLATION" being UN-evidenced nonsense?
Stop your denials/noises, CS. :)

Say, Fizz, you got any science qualifications? You know, degrees, certificates, anything like that from a college or university, maybe even a swimming certificate from the Big House? Your oppos on this site (Strumpo, Irate, et al) all qualified from the university of life but I see you flunked that one.
Captain Stumpy
so spreading lies is all you have?
links/references and evidence or STFU i have repeatedly asked you to substantiate your claims with evidence
to date, here are the numbers
re-BICEP
-almost 6000 posts and still no evidence
re-your ToE
more than 15000 posts, still zero content (mostly because you don't understand how copyright works)
re-any claim about pointing out specific flaws of any kind
absolutely zero links, references or evidence to any actual proof
not a single quote
not a single piece of data
not a single link
not a single reference that can be validated
not a single person that can give me a single link to your claims
not one
ever
period
now... links and evidence or STFU
oh, and reported
:-)

Yes you are batshit crazy and have been brainwashed by QM. Recall, space is continuous and real, the electric field is continuous and real, Planck infers randomness and non-causality. You can't get real from there, you are in the wrong store!

Mmm, I take it that means none. It explains why you come over as thick. Did you go to school?

Yes, the rms value. anyway, you guys should take this off site, maybe a chat room, or email juz say'n

Another wrong conclusion, Reg.
Wishful thinking, Reg.
You are way out of your league, Reg.
It makes you look like a clown.

That would require negative energy.
That has proven to be so difficult that no one has succeeded.
Hilbert space has nothing to do with space time.

Thought you had gone into hibernation, but then you come back with this snappy rejoinder after three weeks.....go back to sleep, Fiz, you need it.
Hyperfuzzy
No, simply common sense!

QM is a stupid tool. What it does is destroy the correct model and then we jury rig our equation by defining the potential and kinetic energy. Unfortunately this leads to solutions with multiple possibilities, i.e. non causal. Our unwise PhD's interpret this as real.
It's just a digitized wave equation with continuity destroyed.

Using a non-causal tool, not theory, no axiomatic properties, etc. to define causality. Do you c an error in logic, not only that, the system is essentially randomized, then a state may exist at a given temperature, probability density function, maybe a Dirac Delta Function. How about an assembly of diametrical spherical fields? Charge is conserved, so why all the BS! Everything we see and everything me measure is just these ghost like objects, apparently never created or destroyed, it's field from its center to infinity, simply the ripples, the rest is food!

Dude, GR, SM? GR: False Assumption: speed of light is the emitted wavelength over the measured period.
SM: The nucleus is held together by coulomb, the neutron is a supposition of an electron and a proton, not a third particle, the 1st particle. The electron and the proton are only spherical fields.

There is no evidence that they are spherical. They are far more likely to be ellipsoids. (Probably easier for you to think of them as pancakes....)
