"Stephen Hawking, one of the world's greatest physicists and cosmologists, is once again warning his fellow humans that our extinction is on the horizon unless we figure out a way to live in space. Not known for conspiracy theories, Hawking's rationale is that the Earth is far too delicate a planet to continue to withstand the barrage of human battering. 'We must continue to go into space for humanity,' Hawking said today, according to the Los Angeles Times. 'We won't survive another 1,000 years without escaping our fragile planet.'"
