>>21726115The universe is eternal, but is also hot and dense, from one species' point of view. In fact, the universe right now is simultaneously:
1. the heat death of the previous aeon or cycle;
2. our current aeon, with planets and stars and life;
3. the infinitely dense, first nanosecond of the big bang of the next aeon.
All 3 are happening right now. All 3 are the same thing, from 3 points of view.
