I've seen movies that touch on parallel dimension theories and I generally find them pretty interesting. We talk about distant solar systems and the possibility of aliens but do you think that parallel dimensions are even possible? For those who have no clue what a parallel dimension is, here's a quick catch up: Parallel universe (fiction - Wikipedia, the free encyclopedia) That's from the Wikipedia page on the Parallel universe concept. I know Wikipedia isn't the best source at times but since as far as we know Parallel universes are completely theoretical, it's going to be hard to find some "facts" anyway. So what are your thoughts? Do parallel dimensions/universes exist in full or in part? If you have any theories feel free to toss them out here for others to discuss.
