Powers of 10 - Cool stuff
I had a fun time drilling down from a cosmic view of things down to quarks on this site. It's worth the ride for a few minutes. It shows us where we fit into the Universe. A couple of powers of ten up and down and we get pretty insignificant.

View the Milky Way at 10 million light years from the Earth. Then move
through space towards the Earth in successive orders of magnitude until you
reach a tall oak tree just outside the buildings of the National High Magnetic
Field Laboratory in Tallahassee, Florida. After that, begin to move from the
actual size of a leaf into a microscopic world that reveals leaf cell walls, the
cell nucleus, chromatin, DNA and finally, into the subatomic universe of
electrons and protons.
