That question makes no sense in terms of this discussion. The heat death of the universe means that there is no "after", just as there was no "before" the Big Bang.

The actual concept of time does not exist (at least in my humble year 12 physics understanding and having read Brief History Of Time a long time ago :) )

It pains me to say this, because it is a masterpiece of vulgarisation, putting arcane physics and cosmology within reach of (still decently-educated) normal people, but it is very outdated in a lot of respects. It badly needs something else.

I found some of Carlo Rovelli’s books to be quite compelling, but they are more focused on the topic of time and space-time. Not really the universe in the same way as Hawking’s were.
