Space Settlement - Colonizing the Cosmos!
: "Today space is mostly rock and radiation. We can change that. In the 1970's Princeton physicist Gerard O'Neill showed that we can build giant orbiting spaceships and live in them. These orbital space colonies could be wonderful places to live; about the size of a California beach town and endowed with weightless recreation, fantastic views, freedom, elbow-room in spades, and great wealth. In time, we may see hundreds of thousands of orbital space colonies in our solar system alone. Unlike earlier colonization events, no people need be oppressed and no ecosystems destroyed for the simple reason that there aren't any out there. If we do it, space colonization will be so important that only the origins of life itself is comparable. Even ocean-based Life's colonization of land half a billion years ago pales by comparison."
