"There are in fact 100 billion galaxies, each of which contain something like a 100 billion stars. Think of how many stars, and planets, and kinds of life there may be in this vast and awesome universe." "We find that we live on an insignificant planet, of a humdrum star, lost in a galaxy, tucked away in some forgotten corner of a universe, in which there are far more galaxies than people." This comes from Carl Sagan's Cosmos episode 7, "The Backbone of Night."
