Yeah iv detected unicorns on Mars also they are horses in the bull domain

so you should get a nobel prize for your bull domain

No, but what it does mean that proving the theory will not be achieved by expecting regular matter and dark matter to interact with one another in the form of an impact. That, as far as it has been explained to me, is a physical impossibility.

You are right impact is impossible.
Now if you get a current flow ( which is at right angles ) from the time domain, it will flow alongside regular current without interacting with the regular current flow. so in other words they co exist

Maybe Erik Verlinde got rid of dark matter, the same way that Einstein got rid of the ‘aether’ (we suppose it’s there – well, it has to be there for our theories to function- but we can’t detect it)?

Emergent Gravity and the Dark Universe

a reply to: Agnost

I've always wondered about gravity as a thermodynamically emergent property, even as an undergraduate I thought it would explain a number of puzzling problems with gravity, but obviously I had no concrete theory how it would arise.

Gravity by its nature is really different---the coupling constants are mass-energy which are weird numbers---in the rest of Standard Model there are integers of charge ratios, not these weird numbers.

It's different by coupling to everything somehow, unlike Standard Model. Stuff interacts with EM if it's is charged and doesn't if not. Strong force (gluons) have a similar rule: either it interacts or not. But somehow gravity interacts with everything---summing it all up, but with weird coefficients.

And of course Dark Matter and now Dark Energy. Plus the theoretical inability to unify gravity. If it's so difficult, then perhaps General Relativity does not actually apply at the microscopic scale, and that's why the theoretical unification has broken down. String theory didn't help matters.

All point to a possibility that we do not yet have the true mechanistic theory of gravity: General Relativity is an amazingly good but classical approximation in the limit, just as fluid mechanics is the classical approximation to the microscopic kinetic theory of atoms in certain statistical/thermodynamic limits.

It's as if maybe gravity as we know it is akin to Van der Waals forces which are weak but really arise from strong underlying electromagnetism.

If Verlande is successful, he will be the next Einstein. Of course there is some strong and legitimate opposition: arxiv.org...

And if we don't yet know the true microscopic theory, when we figure it out---what if it is engineerable? The giant problem today with engineering gravity is that the coupling coefficient is so small, big "G". You need a huge amount of mass-energy to do anything.

But what if gravity was a Van der Waals force which is the small residual of a much more powerful but almost always cancelled microscopic effect? If we can reduce that cancellation somewhat then there would be a much more powerful thing to engineer gravity with.

You are much better educated in physics than I am, but my sentiment about gravity...it is not a force. At all. Gravity being a force is an illusion. For that reason it cannot be explained using some exotic force carriers or Standard Model. It cannot be unified with the rest of the forces because there is no need to...and because it is impossible..for that very same reason. There is no common ground in nature of matter and gravity, only relation in behavior when the two superimposed. With that said, 'unification' has already happened, only not acknowledged directly. Although that's just my own opinion.

If dark matter were a plasma, it could be detected by its interaction with light and... wouldn't be dark. You could detect a cold plasma by its compton upscattering of light, or its absorption of light, or light given off when it recombined into cold atoms, or any number of ways.

Everyone that thinks the dark matter content in galaxy clusters is some sort of plasma is welcome to try detecting it through one of these means. The signal ought to be overwhelming, since dark matter is estimated to compose 9/10 of the mass of galaxy clusters.

Emergent Gravity and the Dark Universe

Well we can detect it we see its effects on gravity. Problem is we don't know what's causing it. It's not a matter of if it exists it's a matter of what is it. Observations show us something is there we even found a galaxy that is 90 percent dark matter. If something wasn't there the stars we do see would just get slung out into the cosmos. But they aren't something is pulling then together. What we may discover is are guesses as to what it may be are entirely wrong. For example I just read a paper a while ago that suggest black holes may exist in quantities far exceeding our estimations. And even went so far as to say there may be several real close to us that we just can't see.

The theory of the paper is below a certain radius we would have difficulty spotting the distortions that occur. And they believed that smaller black holes were created at the big bang and not part of stars collapsing. I doubt they are right but who knows until we can prove otherwise.

As with anything else, give it time.

How about reverse time?

How about reverse time..

'Time reverse' is not possible, imo, as there is no 'anti space' ('reversed time' can be rephrased as 'anti-time'). Does 'anti time' make sense to you when it relates to the concept of 'volume"?
