George Will wrote the following recently in Newsweek: "The sun around which Earth orbits is one of perhaps 400 billion stars in the Milky Way . . . There are perhaps 140 billion galaxies in the still-unfolding universe. If all the stars in the universe were only the size of the head of a pin, they still would fill Miami's Orange Bowl to overflowing more than 3 billion times."
It kind of makes the Space Shuttle's voyage a little insignificant.
