I have read that some cosmological models predict a heat death of the universe. Eventually all matter (beggining with superclusters, clusters, then galaxies, then stars) will lose all energy and separate (due to expansion which will eventually occur even on a galactically local level) so that all energy in U becomes diffuse.
At this point there are no more matter/energy interactions as everything (I think I read something about point particles) is so spread out it is in its own OU.
Can someone more knowledgeable please expand on my statements above?
Also at this point would it be reasonable to say that t=0 again as effectively the second law of thermodynamics becomes irrelevant when change is impossible as all particles exist entirely in their own OU?
