"Ask ten different scientists about the environment, population control, genetics, and you'll get ten different answers. But there is one thing every scientist on the planet agrees on. Whether it happens in a hundred years or a thousand years or a million years, eventually, our sun will grow cold and go out. When that happens, it won't just take us. It will take Marylin Monroe and Lao-Tsu and Einstein and Morabuto and Buddy Holly and Aristophanes. And all of this...all of this...was for nothing unless we go to the stars." -CDR Jeffery Sinclair, Babylon 5, "Infection"
