Heat death leads to absolute uniformity throughout the universe and when that happens, when no two points of the universe differ in any way, the universe becomes a single point and then a big bang occurs, according to Penrose.

Argument was a bit more complicated.

Basically when all particles are moving at speed of light, time becomes meaningless and you can consider space to be infinitely small. I.e. identical conditions to Big Bang
