Scale of the Universe 2

“Scale of the Universe” is an interactive flash applet which lets you zoom in and out over several orders of magnitude in distance. Along the way, you’ll see things like atoms, dust mites, planets, and the edge of the observable universe. This is a really cool way to get some perspective as to just how huge, and how tiny, things can get.
