I'm wondering what is thought or say parrallel or alternate uviverses and dimensions. What would be possible, or better yet, what wouldn't? When i usually consider anything about existince or reality or anything like that (philisophically or theoretically anyways) i always consider the possibilty that this isn't the only reality that exists. I often even forget that most people would assume this was the only real reality. Also, do you think it's possible to enter an other universe or dimension? and... if the universe is infinite how would that effect the possibilty of other universes? how would the expanding effect other universes. and... do other universes or dimensions exist in what we would consider the same "space" as our world???
