Black Holes

[The Seftrex]

I thought the universe was still expanding.

The universe is still expanding but at one point it is theorised, that the Universe will retract. So you could make the assumption the Black hole at the center of the universe (which is impossible to determine techniquely because the universe is still expanding), is not strong enough.

There is also the theory that the universe will continue to expand and dark matter will be all we can see in the night sky as the stars will be so far away.

well, since the universe is ever-expanding, a black hole at the center strong enough to cause the universe to contract would be strong enough to suck in endless galaxies within its area of pull. it would be an interesting look at how the universe would react to the power of a black hole.
