Could 'dark matter' be evidence of interpenetrating other universes?

Question

We study stars because we can see them. We are beginning to find evidence of planets. But most of the universe is made of "dark matter.' Does any testable evidence insist that it is a function of the Big Bang? Does it move in tandem with other celestial phenomena? Is background radiation any different in the presence of dark matter? Does it have any antimatter properties?

Answer 1

Big bang models don't require the existence of dark matter per se, but the existence of dark matter helps support inflation theory, which is needed by those models.

Yes, it does move in tandem with other celestial phenomena - a recent study of interacting galaxies has produced some interesting results, but I can't remember any details. I don't know about the CMB, and I don't think there's any reason to believe it's anti-matter - but how would you tell?

There have been some serious suggestions that there's a connection between dark matter and M-Brane theory, but I don't think it's any more than highly speculative.

Answer 2

Dark matter could not be the evidence of other universe.
Dark matter, could support the theory of inflating model of the Universe. The rest of answer could be found in NASA websites and Wikipedia or Yahoo search engine.

Answer 3

Doubtful. If visible reality is as old as they say it is, which I doubt, it stands to reason that we should've had a nice pileup like unto tectonic plates criss crossing our reality. Sort of like an early Warner Brothers Looney Tune.

Answer 4

Most of your answers can be found right on the NASA website. They have articles about the information you are seeking I do believe.
