Time theory: Time is composed of instances, for example, if I lay a card down (card=instance), then I rip it up and lay another one down. By this theory, it proves that time travel is impossible because the past no longer exists and the future hasn't happend yet so we can only travel in the instant that we exist in. Universal/God theory: Science says that a being such as a "god" is most likley improbable. However, every event has a cause (a swing is pushed) and every cause has a cause. So if the universe had a beginging (big bang), there must have been a prime mover, which if the universe did have a begining, I beleive that this "prime mover" would be the closest to "god". However the "prime mover" can only exist if the universe had a begining, meaning that if the universe was ever present, this means that at any given moment, an eternity has passed. And also that if there is a "god", it must hold the universe for every instant that passes by. Dimension theory: Should other dimnesions exist, I beleive that the best way to explain them is as different frequencies, like a radio. You stay where you are, but you "tune in" to a different frequency. Any thoughts?
