[Oh Prompto honey. He won't correct that, because, okay, it would also be awesome in that sense, too, but c'mon.]

I prefer to deal with what I know to be true and what I know to be possible. I haven't found evidence for such a thing, but I also haven't looked for any. There's nothing I know of personally to discredit the idea of other worlds--the universe is near infinite and expanding, after all--or of alternate dimensions, though that delves into quantum mechanics I haven't spent much time with.
