Sort of. There'll probably never be a way to prove whether or not parallel universes exist, but it's fun to think about what a parallel universe, if there is one, might be like.

Over time, I've formulated a theory that the universe(s) has/have somewhere between five and eight dimensions, and one of the possible dimensions is alternate universes. The complete list is as follows:

- time
- height
- width
- depth
- a dimension that the universe(s) sometimes end(s) up partially folded across to create wormholes
- heaven & hell (As in, heaven is in one hidden direction from our universe and hell is in the opposite direction; I'm not certain that that's how it is, but I think it's quite likely)
- dream worlds (Similar to the heaven/hell dimension, good dreams are in one direction and bad dreams are in the other, though in heaven good dreams would be on both sides and in hell bad dreams would be on both. I think this dimension is somewhat less likely to exist than heaven and hell as a dimension, but still likely.)
- alternate universes (i.e. if you somehow took a step along this dimension you might end up in a universe where I'm married to Enya, then if you took another step you might end up in a universe where I'm related to Enya, etc.)
