Tell me you didn't take that from a modest mouse song...haha.
But uh, the exact size of the Universe is unmeasurable. It's either so big that within the current scope of human technology, it will be a long long time before we are able to measure it, or it's infinite, and still expanding more and more beyond that.
As for a shape, the hyperbolic universe makes the most sense based on what I've read, which really isn't much so I guess I can't really answer that. Though has anyone looked into the theory of the multiverse? It seems pretty interesting, though it seems pretty unlikely..
