"Not sure how that'd work, but I have to question the assumption that our worlds are gone in the first place. I don't know about anyone else, but I didn't see anything that resembled the end of the world. That, and I find it hard to believe that any human could survive a force that was strong enough to reach between universes and destroy a planet. My guess is still that something basically teleported us and the land around us here, and back home there's a crater and missing-persons reports."
