What would happen if the Universe just keeps on merrily expanding?
I have read that maybe all that will be left would be a big black hole, or black holes.
I have heard that all matter disintegrates, eventually; is that considered mainstream?
I don't want to know about big crunches etc... I am just interested in what would happen to the matter, planets, neutron stars, etc, given a long enough length of time.
There was the idea, in the LHC thread, about how there might be black holes inside white dwarfs, gradually eating them away, and heating them up at the same time...which was interesting.
