Well I haven’t seen that episode but it is based on the same concept, I saw that in a Horizon episode talking about the shape of our universe, you can see the asteroids universe here http://www.dailymotion.com/video/x18wu9y_horizon-2009-alan-and-marcus-go-forth-and-multiply-pdtv-remax_lifestyle
at minute 52, is a great show.
Man, it’s great that you cached that
Cheers!!
