Stephen Hawking's giving us all about 1,000 years to find a new place to live

Unless we can figure out how to get the heck off this planet. Then ask noted theoretical scientist and astronomer Stephen Hawking. He says humanity won't survive another 1,000 years on Earth because of, you know, the usual suspects -- climate change, nukes, robots. Hawking, speaking earlier this week at Oxford University Union, says our best chance for survival as a species is to leave the only home we've ever known and establish colonies on other planets. "Although the chance of a disaster to planet Earth in a given year may be quite low, it adds up over time, and becomes a near certainty in the next 1,000 or 10,000 years," Hawking said in the speech, according to the Christian Science Monitor.
