What eventually happens to black holes? Every galaxy has at least one in the center, and they seem to be plentiful in space. Do they just keep devouring matter forever and ever? It doesn’t seem plausible that they could eventually eat up everything in the universe.

I wonder if our universe didn’t originate from one huge black hole 13.8 billion years ago because every element created has got to be in a black hole. And the gravity of a black hole seems to be able to devour any and everything. Like some gigantic space cycle. The Hoover of the universe, then the vacuum bag bursts.
