Power of Ten

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.

Nothing like a little perspective.

Carl Sagan said that while he believed in extraterrestrial life, he didn't believe that beings from other planets have been here. He said that the sheer vastness of space would make such visits impossible by any known means. For an idea of how he thought it could be done (maybe), I recommend the movie Contact.
