The heat death has everything spread out so your visible universe holds only you more or less. The most extreme models say matter to be torn to atoms, the less extreme expect solar systems to survive, maybe even galaxies.
Both agree the black holes will evaporate to nothing but Hawking radiation
Yeah the whole “big rip” or whatever the colloquial term is, is an interesting one to think about if the expansion just keeps on accelerating.
But from what science news I follow, I think our models and theories in that area are in for a shake-up. It will be interesting to see!
I think that is kind of orthogonal to the concept of heat death, though, which is more about entropy. Any universe that has a solar system or galaxy in it is far from reaching the state of heat death.
