Thanks, I will show this to my 7 yo son! 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". It was a celluloid version of the same thing shown here, and it was very good for teaching me the scales of the universe when I was a young proto-physicist. Rowan.

Hello,
this flash animation (interactive) shows the scale of common things from the planck size to giant clusters up to the known universe which is 10^27 meters.
Have fun, it's worth a look.
and a nice day. Simon Plouffe
