Carl Sagan
“Since, in the long run, every planetary civilization will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring--not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive... If our long-term survival is at stake, we have a basic responsibility to our species to venture to other worlds.”
Carl Sagan

Albert Einstein
“Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.”
Albert Einstein
