My understanding is fully based on pop-sci, but: Eventually the influence of gravity starts generating black holes, which are really high entropy objects (in fact, for a given region of space, you can't actually fit any more entropy into it than a black hole does). So it seems to me that stars and planets and so on are intermediate steps between a hot, low-entropy universe at one end and a cold, high-entropy universe consisting of black holes. Eventually the black holes maybe evaporate leaving an extremely fine mist of radiation, but by that point space will have stretched out the the point that the undiffentiated radiation cannot collapse again. I found this from an actual physicist: "our gravitationally bound ball of gas has a negative specific heat! In other words, the less energy it has, the hotter it gets." https://math.ucr.edu/home/baez/entropy.html https://math.ucr.edu/home/baez/entropy.html
