Stephen Hawking: Abandon Earth Or Face Extinction

Big Think reruns Stephen Hawking’s earlier warning of 2006, namely that we need to think about moving off the planet:

So, according to famed theoretical physicist Stephen Hawking, it’s time to free ourselves from Mother Earth. “I believe that the long-term future of the human race must be in space,” Hawking tells Big Think. “It will be difficult enough to avoid disaster on planet Earth in the next hundred years, let alone the next thousand, or million. The human race shouldn’t have all its eggs in one basket, or on one planet. Let’s hope we can avoid dropping the basket until we have spread the load.”

Hawking says he is an optimist, but his outlook for the future of man’s existence is fairly bleak. In the recent past, humankind’s survival has been nothing short of “a question of touch and go” he says, citing the Cuban Missile Crisis in 1963 as just one example of how man has narrowly escaped extinction. According to the Federation of American Scientists there are still about 22,600 stockpiled nuclear weapons scattered around the planet, 7,770 of which are still operational. In light of the inability of nuclear states to commit to a global nuclear non-proliferation treaty, the threat of a nuclear holocaust has not subsided.

In fact, “the frequency of such occasions is likely to increase in the future,” says Hawking, “We shall need great care and judgment to negotiate them all successfully.” (…)


 
Cosmos Magazine featured an article by Hawking earlier this week called To Boldly Go: My Life in Physics, which is a edited version of the address he gave at the Perimeter Institute in Waterloo, Canada in June this year.
