What Happens to the Universe in the Big Freeze?

[BrownDwarf]

I understand the gist of the big freeze, and its relating topics i.e. cosmological constant, dark energy but I can't seem to find the specifics of what happens to the universe. Could someone help me out?

Note that it is all more or less speculative at this stage. Also note we have a cosmology forum, where you can post more detailed questions. Finally, just in case, please read forum rules.
