Does dark matter move

Answer 1

We don't even know what dark matter is, let alone if it decays. One possibility is something called sterile neutrinos; neutrinos that do not interact via the weak force. If so, it's unlikely that they'd decay, though they might undergo neutrino oscillation. If not that, it's likely something even more exotic which we don't know anything about yet (other than it interacts with normal matter through the gravitational force, and not through any of the other forces).

Answer 2

No. Pretty much nothing comes from black holes.

We don't know exactly what dark matter is. There are several candidates that go by names like WIMPs (weakly interacting massive particles) and MACHOs (massive compact halo objects). Black holes could actually be MACHOs, though they're likely not the only kind.

Answer 3

Dark matter does move, but it interacts with other matter primarily through gravitational forces rather than through electromagnetic forces. This makes it difficult to directly detect or observe, but its presence can be inferred through its gravitational effects on visible matter.

Answer 4

no there is no evidence however we believe that it would be dark energy

Answer 5

yes, many think that dark matter isn't affected by regular matter, so it can simply pass through at high speeds.
