how would heat death at the end of the universe work if energy cant be destroyed or created?

Question

I learned about the energy only changes form recently and was wondering how heat death in the end of the universe would work because “all energy is lost from the universe”

Answer 1

It’s called heat death because all energy is tuned to heat, it’s not lost, it’s spread out everywhere in an infinitely explaining universe, so effectively the energy density is so small that it might as well be zero and even then it’s so spread out that it’s impossible to use any of it
