Well, like, how we're on an Earth right now, but it isn't Earth Earth, y'know?

[ Yes, exactly like that! ]

There used to be infinite universes and then there was just one universe and then there were exactly fifty-two universes, which seems, very… specific? I guess? But I don't know where we are now, I'm pretty sure some of the universes got pulled together or split apart, and you can't really tell when that happens. It just does.
