Except we have good evidence that the universe is very close to flat, space-time wise.

A hypothesis that there's local unexplained curvature...Well that's really what dark matter is all about. What's curving it?

edit: Just ignore my comment, it's wrong.

(for posterity) My understanding is that spacetime being flat is akin to it being the surface of the universe's curves. Explain, expand, or correct me if that's wrong; I'm certainly no physicist.
