Wikiquote:Quote of the day/September 11, 2008

  Although September 11 was horrible, it didn't threaten the survival of the human race, like nuclear weapons do. ... I don't think the human race will survive the next thousand years, unless we spread into space. There are too many accidents that can befall life on a single planet. But I'm an optimist. We will reach out to the stars. ~ Stephen Hawking
