Proof That Spacetime is Flat?

As a followup to my last entry (Is Spacetime Flat or Curved?), here's a very nicely presented youtube movie which demonstrates why cosmologists believe the WMAP data shows the universe is flat to within a small margin of error. As I've said many times before, I believe that margin of error is eventually going to reveal that there is a slight curvature to our spacetime, but if you watch this video you'll see a good explanation of the opposing viewpoint.
