All the glory of the universe, in a single Flash app

From the femtometer to the light year, Universcale spans
40 magnitudes of measurement into a single cosmic Web
application.

It's really amazing when you zoom all the way out into stars
and galaxies and then realize that every time you go a
magnitude higher, everything you saw before, from the flea
to Mount Everest, is contained in this tiny little grid in the
lower-left side of the screen.

Of course, the Carl Sagan-should-be-narrating-this planetarium
music helps. Left click to skip intro and click on size numbers
