New theory of gravity might explain dark matter
The title is misleading. If his theory were correct, dark matter would not be needed.
A better title would be "New theory of gravity might explain away dark matter".
... how does Dr. Verlinde account for the center of gravity being offset from visible matter in disturbed galaxies like the Bullet Cluster? Or something like Dragonfly 44, a large mass with very few visible stars?
Face it, no one has ever really seen the effect of "special relativity",
A better title would be "New theory of gravity might explain away dark matter".
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).
What about gravitational waves? A wave does not necessarily point to a particle, but strongly suggests one might exist. If a graviton exists, as we know that gravity waves do (thanks to LIGO) then gravity is a fundamental force, not an emergent property.
This "dark" is the ether which is immobile in an infinite universeThen, how do you explain the measurable fact that light speed is constant independently of your own speed? Obviously you don't have f.idea about physics. Still, you are wasting the opportunity to go to a physics forum to read, learn, and ask questions to other mates, who will be happy to help BTW. But here you are wasting your time (and ours) like you were doing at school. But for talking bullshit please go to religious forums, this is not your place. Otherwise just try to think by yourself, I know it is difficult when you have received a religious brain wash when you where little, But those who tried hard were able to quit from religion and start thinking by themselves. It is up to you.
Reg blurted, "Well, LIGO measured something, but was it gravity waves? I suggest they measured perturbations in TIME, which is known to be subjective."
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.
Well, LIGO measured something, but was it gravity waves? I suggest they measured perturbations in TIME
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.
What are the chance you'll find new physic? It's like hoping for some miracle like the one Einstein stumble on
Well, LIGO measured something, but was it gravity waves? I suggest they measured perturbations in TIME
Oh boy...where to begin. Frankly it boils down to: You didn't even look at the LIGO signal (much less the shape of it)...or you don't really understand why it has that particular shape.
Otherwise you would have immediately refrained from posting this BS.
You accuse me of posting BS, but you close your mind to any other interpretation without a thought. You are hardly a fine example of the modern scientist with an inquiring mind
... intensive Calculus based science curriculum …You can say that again. Congrats to him, and thanks in no small part to his efforts at exposing the "rigged system," may the people find some solace in the knowledge of the democratic illegitimacy of the results. But should he fail to "drain the swamp," will he still say, as he did of his opponent, that our recourse is refuge in the second amendment? Will he need to ask for Putin's help again? Is it okay if we ask? Better buckle up and break out your slide rule, Benni, we're all goin' for a ride ... meet the new boss, Benni, same as the old boss – on steroids, with a fully loaded and equally rigged legislature (he ain't gonna drain nothin') ...
Go Trump
Any serious physicist, or even serious armchair wanna-be, knows that the physics we understand are incomplete.
You still don't get it. They're measuring a transient distortion of spacetime. It's a wave.
You can't treat time as if it was not part of spacetime, any more than you can have pea soup without peas.
Is the last line of the ninth paragraph supposed to be "the result of the additional information in the bulk of space is a force that nicely matches that attributed to dark energy."Nope, it's correct as written, "... attributed to dark matter." Refer to the abstract (arXiv link at the end of the article).
Any serious physicist, or even serious armchair wanna-be, knows that the physics we understand are incomplete.
We don't need more cranks on this forum; we have plenty. Rather than expose your ignorance with silly prattle, study physics and learn it.
I suggest they measured perturbations in TIME, which is known to be subjective.I guess. I would need to know perturbations in WHAT time. For example you might be talking about a wave, in which case you mean one period.
The state of displacement of the superfluid dark matter is gravity.Your definition implies some kind of force exerted by the superfluid. That force is the force of expansion of spacetime. That force alone does not directly cause gravity. You have to have some displacement in that force, as you say. Visible matter does the displacement which we call gravity. But displacements appear to occur with any non-uniformity in the expansion. Nothing is perfectly uniform in the macro world so we will be seeing non-uniformities occurring without any visible matter in the neighborhood. So we end up with what we think is dark matter. It's a cruel joke, I know. Nature gets the last laugh, as usual.
Well, LIGO measured something, but was it gravity waves? I suggest they measured perturbations in TIME, which is known to be subjective.Perturbations in the time required for the laser beams to reach the mirror. Meaning perturbations in the actual distances between the arms of the interferometer. Gravity being a force, not a distance, I would say it is not a gravity wave, only changes in spatial distance. The source of the disturbance may be caused by gravitational in-spirals, but such disturbances could occur as a result of some head-on collision just as well. The ringing form of the signal tells them which type they're seeing. For example they estimated the separate masses of the colliding black holes. In other words, a shock wave travelling through spacetime, but whether this has anything to do with gravity or not has to be determined by the interpretation of the signal.
I merely point out that the measurements did not necessarily show gravity waves, there are other explanations.So noted. Thanks.
I did not say space/time, which is a mathematical concept.Well ok. I'd say we exist in space, but we live in spacetime, time being a change in spatial configuration (sequential change, unless you're made of antimatter, the laws of physics generally working equally well in either direction).
Reg raved, "...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."
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.
The best part: "Thus, a perturbation in time will manifest as a change in the length of the LIGO pathways as measured by a laser." Reg can say this with a straight face and not comprehend that he is talking about measuring spacetime.
Reg, here's some advice. We don't need more cranks on this forum; we have plenty. Rather than expose your ignorance with silly prattle, study physics and learn it. Or go collect bottle caps. The latter is likely to be far more productive for you.
I suggest they measured perturbations in TIME, which is known to be subjective.I guess. I would need to know perturbations in WHAT time. For example you might be talking about a wave, in which case you mean one period.
Read my previous comment to Seeker2.I said that what they measured was a perturbation in TIME.
define "TIME".
You are a pedantic twit. (I know, back to the insults, but this one is irresistible!)I did not say space/time, which is a mathematical concept.You will find "spacetime", but not "space/time" in any textbook. What is it? :)
Look, a wave is merely a measurement which builds to a peak and then drops away again. Why is this particular shape in this particular case a direct manifestation of the presence of a "gravity wave". Is there some special feature of it that only you can see? Point it out.I merely point out that the measurements did not necessarily show gravity waves,You point out nothing, you make a baseless claim.:)
So, only explanations you agree with can possibly be right? You are a GENIUS! (There, that makes up for calling you a twit...)there are other explanations.Only wrong ones :) .

........real-world phenomena like dark matterWhat? ........"real world"? What is "real world" about DM if it has never been isolated to prove it's existence?
Nothing is perfectly uniform in the macro world so we will be seeing non-uniformities occurring without any visible matterSeeker, comparing what you wrote with what Einstein wrote in GR:
Face it, no one has ever really seen the effect of "special relativity",
Ya know, I use a navigation system in my car pretty frequently. That wouldn't work with nearly the precision it does if it weren't for the clever guys and girls who set it up taking general and special relativity into account in their algorithms.
You are, of course, free to believe that it doesn't work that way. But it's easy to confirm: just go ask them.
It should be mentioned that, if "general relativity" were founded on some independent principle, brushing it aside would be trivial to the rest of "science". But "general relativity" is based on "special relativity". Essentially, it says that the formulas and analyses necessary to explain gravity can be derived simply by invoking the behavior of simple acceleration in empty space, using derivations of "special relativity". But, if "general relativity" proves not effective, "special relativity" can have flaws, too. Face it, no one has ever really seen the effect of "special relativity", only the assertions of "scientists" that it occurs.
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.
@Benni: You don't need to "isolate" something to observe it.......it's never been OBSERVED either. You got pics?
No one has proposed something is "missing"Oh please, you DM Enthusiasts can never stop talking about the 80-95% Missing Mass.
DM is an observed excess.....Ok, show us the DM pics, I'd like to see what color this stuff is.
and it is especially easy to see in the cosmic background if your are interested in how we observe it.If it is so easy to "observe", show us the pics.
tgbl.......see what you started? Now the zany Zwicky family member wants pics of neutrinos.
Yes, but from you Benni.................I loaned them to Schneibo & he has refused to give them back. So if you want to see them, Schneibo is your man, he has also stated that he has pics of BHs.
Or are you now also claiming that neutrino's do not exist?
Why not, you clowns just claim anything.
@SIS
I find it hard to accept that we would have to dig this deep to arrive at a quantum theory of gravity. My gut feeling is that quantum gravity should be much more straightforward.
Face it, no one has ever really seen the effect of "special relativity", only the assertions of "scientists" that it occurs.
Willful ignorance.
You need evidence, man, evidence,
Verlinde needs evidence, not me.
You lost track of the subject.
However, what are observable predictions of the theory in a mentioned paper?This theory is nonsense. The dark matter field has different shape around objects of different size, it forms filaments, disk, rings and/or spherical clouds - i.e. its radial dependence differs from object to object.
@benni........well let's just hope that his policies take a big enough bite out of your monthly welfare check that it will force you back into the workforce to become a productive human being again.
Of course you support Trump. The only way he could be more antiscience would be if he believed in Nibiru, Lysenkoism, or the stuff coming out of your mouth.
@ Reggie the Clown
Of course Verlinde needs evidence.
You are just stringing words together in meaningless ways.
Are you perhaps a bot ?
...the universe will be quasi-spherical.Certainly. But you will also hear spacetime is curved. That's because objects passing through it have curved trajectories. But that's only gravity. But overall light travels in a straight line within about 1%. So overall the U is not curved. Therefore they call it flat. Actually it means the U is in free fall. If it wasn't it would mean there is some multiverse or branes or something else out there. But just because we are not accelerating doesn't mean there is no multiverse out there. It only means there is no spacetime expansion between us and the other multiverses.
I would need to know perturbations in WHAT time.
Are you actually asking what time it is?No. Pick a time. ANY time. Now tell me what the purturbations are re this time.
Switch on the clock thingy on your screen.
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).Space is to spacetime as single frames are to movies. Maybe they should call it movie time.
Its a bit like Einstein's spacetime continuum with dimples in it caused by mass which causes the effect of gravity.Sure does but it doesn't have to be caused by gravity. Nothing is perfect in the macro world.
GPS is running without any reliance on some GR based correction calculations.GPS has to know your altitude before it can calculate your time and position.
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.Regardless of Einstein's ideas about hidden variables, I don't think any well-founded model is going to explain natural variablilty such as that in spacetime entropy.
Spacetime is a concept which mixes apples and pairs.A unit of time is defined simply as a repeating sequence of some particular 3-dimensional spatial configuration. I don't see any problem like mixing apples and oranges.
The quantum nature of TIME itself provides the phenomenon we perceive as gravity.Ok the unit of time may be one orbit around the sun, or whatever. But I don't think this time is quantized. Now the time necessary to orbit some nucleus may be quantized. But I don't think electron orbits are due to gravity. That would be an EMF.
What is "real world" about DM if it has never been isolated to prove it's existence?I think there's plenty of evidence to prove what they think is caused by DM without needing to isolate it.
So now you want to launch into yet another theory about "inferred gravity".....one more thing for which there is no EVIDENCE...I certainly agree. Why would you launch into another theory for which there is no evidence?
Also recall Newton's question, "What is in mass that causes this field?"Poor guy. He never heard of expanding spacetime, I presume.
The rate of change of time is 1.1 what?
The rate of change of time is 1.
Sounds like he's talking about perturbations in the rate of time passage, So this is perturbations in 1?. Interesting. How subjective is this? Or maybe he's talking about perturbations in time of arrival.?
I suggest they measured perturbations in TIME, which is known to be subjective.
The rate of change of time is 1.
The rate of change of time would be time/time so it's a ratio of like quantities and therefore a pure number, and doesn't need units.Sounds like the rate of change of time passage.

Time does not exist. It is a man made concept.

Totally, my bat$hit crazy theory, but I'm owning it.
Then why do electrons 'tunnel' as a probabilistic function, rather than a stream? QM works just fine. My batshit crazy theory attempts to explain how QM becomes so random at the smaller levels and becomes less random at the larger and then on macroscales can become a force currently called "Dark Energy" . It'll take a book to explain properly.
@FizzWun
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.
None of your business, Reg.
You can't "average out" an emission spectrum, the energy is there in a discrete amount or it isn't. As described by QM. But really? Questioning QM, it's the most robust mathematical model ever devised, that has astounding predictive abilities about the behavior of matter and energy. And you tackle it like it's a cult?
I would like to see the possibility examined that dark matter and energy is nothing more than the faster than light matter influence on regular matter. Faster than light matter, if it would exist, has an arrow of time in reverse, and all fundamental forces operate with a negative time component consequently in the opposite direction. The gravitional force would push away matter instead of pull it together (other fundamental forces would not apply as only the gravitional force works over long distances). Galaxies would be surrounded by faster than light pushing on it gravitationally, causing the observed discrepancies of the rotation of Galaxies. And also of the accelerating expansion of the universe.
Stupidity! I have a better understanding of dark matter, black holes and gravity. Join me in LinkedIn (E-mail: a70bvek @ mail.ru , a70bvek @ gmail.com), there is published my project of quantum physics (looking for funding and specialists), in which there is an explanation for dark matter, black holes and gravity. My scientific work will give humanity an inexhaustible source of clean energy and the possibility of space travel. http:// www. linkedin. com/in/cybersystems (professional profile)
@SISI'm leaning towards repulsive gravity. So if you can make a theory of expanding spacetime into a quantum theory it should be no problem. Especially if you can model spacetime as a Hilbert space.
I find it hard to accept that we would have to dig this deep to arrive at a quantum theory of gravity. My gut feeling is that quantum gravity should be much more straightforward.
I'm leaning towards repulsive gravity.
That would require negative energy.It requires expanding spacetime. Is that what you call negative energy?
It requires expanding spacetime.I believe Erik Verlinde would say it emanates from expanding spacetime.
Hilbert space has nothing to do with space time.Hilbert space allows us to describe spacetime in a form which exhibits exponential expansion. It's amazing we're just beginning to catch on to accelerating expansion.
Well Einstein is incorrect, the wavelet changes little in free space; thus, the speed of the wavelet is the original or emitted wavelength divided by the measured period, obvious and common sense, thus any reference to this, Dr. E, is nonsense begets more nonsense..More AWT theory?
None of your business, Reg.
Mmm, I take it that means none.
Another wrong conclusion, Reg.It explains why you come over as thick.
Wishful thinking, Reg.
You are way out of your league, Reg.
It makes you look like a clown.
