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
I always interpreted "heat death" as "the death of heat" instead of "a hot death"
Your interpretation is correct.
You are correct and I misremembered it. "The Big Freeze" and "Heat Death" are the same thing. Thats when everything expands until there is no more heat.
If someone knows the correct terms for what I am talking about please let me know. Let me explain further.
What I am talking about is the opposite of heat death, which is somehow in my mind at a hot death? Basically, where everything goes back to one singularity instead of expanding forever.
Big crunch is what I've heard it called but I don't know if that's what you're thinking of. Googling that might give you a start though.
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
