Humans to Leave Earth Behind?

World-renowned smart guy scientist Stephen Hawking, who's no doubt an avid Gizmodo reader, yesterday gave a speech where he detailed what humanity needs to do in order to survive as a species: leave Earth. That's right, provided we don't blow ourselves up or succumb to a superbug—genetically engineered or otherwise—Hawking believes that humanity's only chance for long-term survival is not to go West (young man), but to go outward, with an eye toward Mars, specifically.

"It is important for the human race to spread out into space for the survival of the species," said the wheelchair-bound theoretical physicist. If what he believes holds true, humans should have a colony on the Red Planet in 20 years and a permanent base in 40 years. So long as my iPod works on Mars, I'm all for it.
