1. I understand an expanding gas has increasing entropy and at a cosmic scale the universe is an expanding gas...sort of. 2. back before the universe was cool enough to form atoms it would seem to be very disordered, ie a high temperature universe of a plasma made of nuclei and elementary particles in random motion and lots of energy. The temperature dropped until atoms formed......and then galaxies. 3. Galaxies seem more ordered than a hot plasma of elementary particles How do these three phenomena add up to increasing entropy?? thanks any ideas.
