Re: [math-fun] the scale of our known universe

When I was a boy growing up in Texas I used to go to the Wednesday Night Physics Movies at UT, and one of the movies they played was called something like "Orders of Magnitude".

'Powers of Ten', maybe? http://www.youtube.com/watch?v=0fKBhvDjuy0 When I saw it, I thought 'Orders of Magnitude' would sound far more dramatic. Sincerely, Adam P. Goucher
