Hey guys, I am a physics newbie that just gone done watching parallel universes. From what I understand M-theory predicts that our universe is a brane that all matter is attached to, and its floating in a 11 dimensional space. Is the 11 dimensional space infinite or finite? Also are the paralled universes that are believed by some to exist; literally parallel to our brane. Is it possible to determine which direction our brane is heading in the 11 dimensional space?
