Wait, I thought the heat death of the universe ment it all got so hot nothing survived… Does it literally mean heat will die and it’s going to be cold?
Yes. To my understanding, it’s when all the things in space drift so far apart due to the expansion of the universe that all the atoms and energy are spread so thin that there is nothing left but empty, cold, void.
The antithesis to Heat Death is “The Big Crunch” where the expansion of the universe stops and then starts to go back into itself until there is only a singularity like the one that the big bang originated from.
Eventually the distant galaxies will fade into memory as their light is lost to the expansion of the universe, then the stars will all burn out, the radioactive materials will all decay, and black holes evaporate in the final flashes of light to illuminate the universe.
With no sources of heat left, what remains gets down near absolute zero as residual energy is lost as infrared radiation. The heat death of the universe is the long, cold dark at the end of everything.
“This sucks. I should have brought a jacket. I’m fuckin cold.”

I liked when they called it the Great Gnab, as it’s the reverse of bang.
Basically, yeah.
