the 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.   rmal_cyclic_cosmology
