Isnt what science calls dark matter of the Universe really the antithesis of mass?

Answer 1

Is dark matter the same as a black hole in space? Gravity is so strong in a black hole that things "fall into it."

Answer 2

First Dark Matter is really a linguistic placeholder because simply no one knows what it really is. They know that Dark Matter does not emit or reflect enough electro magnetic radiation to be directly observed. but they can be observed by detecting the gravitational effects on visible matter. In regards to them being associated to black holes, I would say the current definition of a Black Hole does not characteristically appear the same (they may share a couple of traits but nothing significant). Thus I wouldn't say it is antithesis of mass since no one has really figured out what it is.

Answer 3

No one knows what dark matter is. The only reason we think it exists is the fact that the Universe is not only expanding, but that the rate of expansion is accelerating! Given the collective power of all the gravity in the Universe, this should not be happening. There is no known force to explain this accelerating expansion of the Universe. There is nothing that we can see that accounts for this expansion. The existence of dark matter is one way to try to explain it.

One thing we do know; the expansion of the Universe is accelerating. We don't know why.

Answer 4

No. Scientists haven't yet figured out that space is simply the name given to where there is no matter. So, because they haven't figured that out, they insist there is something between the matter in space. Hence, the hypothesis of dark matter -- "even though we cant see it, it must be there because we cant think of anything else."
