What would it take to kick start a dead universe? Once a universe is finished, can it rise from the dead?
I've heard of heat death and cool death.
Heat death doesn't necessarily mean everything is frozen does it? Is it a total loss of energy or is it a lot of energy available but no work can be done?
Cool death, correct me if I'm wrong, is the total decay of the universe with no way to ever reassemble?
Either way, can a dead universe come back to life? If so, is there a mechanism currently known that could precipitate a rising from the dead?
