"finite but unbounded"
At the risk of sounding like Doc Brown, it's difficult for us to think sufficiently-dimensionally. Here's the analogy I first heard.

Imagine beings who can only perceive two dimensions, living on the surface of a large sphere, so to them the world appears flat, but however far they go, they never fall off the edge. Strange.

We, on the other hand, are able to appreciate the fact that there's a third dimension. So we know what's really going on.

Just add a dimension or two, and you have us, and our appreciation of the Universe.

I think. (Though it makes my brain hurt.)

I think I'm going to be sick
I just can't handle stuff like that. I think I might be inbred or something.
