Yesterday afternoon Lyn and I watched this quite interesting documentary about Multiverse Theory. I must say it appealed to me. I hadn’t heard much about it before, but to me, the idea of universes outside of our own seems to be quite logical. As the program itself admits, the theory isn’t without it’s detractors, but it is gaining traction. However, it left me with a small question I’d just like to pose on here: if there are billions more universes outside our own, would that not explain why the universe is expanding? Presumably each universe has gravity, so they would draw other universes towards each other. Would that not solve the problem of expansion currently bugging cosmologists, or am I missing something? Answers i comments please,

Mind you, if multverse theory is correct, an extra verse will have to be added to this song.
