What do you think about the compatibility of the physical end of the universe and Christian eschatology. What will the new creation be made out of?
Looks like you're really thinking ahead! The end of the universe is still a large unknown since Dark Energy is such a large unknown. Will DE weaken in time, or will acceleration continue? If it is the latter, there will be a gigantic hydrogen energy reserve that will support millions of civilizations. The Big Crunch alternative is more formidable.
