In recent times, famed astrophysicist Stephen Hawking has become something of a hawk when it comes to human survival.
His fears have been profound. His warnings have been chilling.
He told us earthlings just last year that aliens might swoop down on us and devour us whole, while plundering what's worth taking from here. You know, a few Ferraris, an iPhone or two, Selma Blair, Yosemite, Aziza restaurant in San Francisco, and a couple of Himalayas just to look at.
Now, according to The Canadian Press, Hawking is adamant that we have to start colonizing out there before we endure a Waterloo down here.
In a speech in Waterloo, Ontario--the home of the thriving Research In Motion--Hawking said it's nice that humankind has developed technical abilities to make its environment a lovely (or not) place, but that our sheer selfishness and aggression--yes, not only in America--will be our undoing.
"Our only chance of long-term survival is not to remain lurking on planet Earth, but to spread out into space," he said.
