Sorry, you must be a member of the group to do that. Join this group.
We’ll see that if space extends infinitely far—a proposition that is consistent with all observations and that is part of the cosmological model favored by many physicists and astronomers—then there must be realms out there (likely way out there) where copies of you and me and everything else are enjoying alternate versions of the reality we experience here.
So if there is enough space and I look far enough I'll find myself? How is that not pure assertion via imagination?
