At some point wouldn't gravity override the expansion and cause a contraction again?
Heres a great source
It explains why the universe will have a cold death instead of a heat death.
Right now the universe is expanding and its expanding faster today than yesterday. Things could change, but current math points to a cold death
That IS the heat death of the universe. It's not heat death as in "a wave of heat destroys everything" or anything like that, it's heat death as in "there is no more heat(aka condensed energy), everything is equally cold(aka lack of condensed energy) everywhere. Heat itself is gone, has died".
That is correct and I misremembered. For some reason a heat death makes me think of going back to a singularity because a singularity would probably be the hottest thing ever. Ironically, a heat death would be really cold
