Our home 3+1 dimensional universe has the topology of a 4-sphere. ![]() ![]() Or that making clones of yourself that differ in just enough of a way that they have no place anywhere is a major sacrifice, because you might "be" one of those clones.īut there were a few things about the cosmology (particularly the dimensional structure of the universe) that didn't make much sense to me, or at least wasn't consistent with the way the characters were behaving. They're not afraid of any of their physical forms dying, what they're afraid of is changing too much, especially if they leave one of their earlier copies in stasis, and not being able to re-merge, because that would be too much "like" dying.
