I listened to a podcast today by a theoretical physicist about competing theories for the origin of the universe. I didn't really understand it, or, using the commutative law of grammar, I really didn't understand it. I think I would have been disappointed if I had.
If I did understand one part (see above), then an enclosed volume of space can be represented by points on the surface of the enclosure. If so, then the whole universe might, á la Plato, be just a drive-in movie in some other dimensions. I think I play the lovable loser.
The other part discussed whether the universe began with a big bang, or if it was a continual oscillation between two 3 dimensional universes separated by a 7th dimensional gap, although neither theory seemed to explain where it all came from much better than the idea that the universe is supported on the back of a turtle who is standing on another turtle all the way down. Still one phrase caught my ear, "The trend is toward negative infinity." I don't know what he was talking about, but that's my new explanation for everything.
