We have this universe, and it isn't infinite, yet it is infinitely expanding at the speed of light. No one knows what is beyond the end of the universe, and we can't even see its end. If we have the one big bang, (plz no religion in this, I am religious, I just want this to be theoretical/hypothetical) and that takes most of the dark matter in our universe (remember just in our universe) that means we can assume there is other dark matter beyond the pretty much infinite expansion we call home. Many media outlets especially comic books, have discussed two universes colliding (like that's what it would take to permanently kill deadpool or the old wolverine.) I want to hear your theories on this, please don't post irrelevant posts here, ONLY IF IT RELATES TO THE TOPIC are you to post arguments.
