Hawking: If we survive the next 200 years, we should be OK

Professor Stephen Hawking, one of the world’s great scientists, is looking to the stars to save the human race — but pessimism is overriding his natural optimism.

Hawking, in an exclusive CNN interview, said that if humans can survive the next 200 years and learn to live in space, then our future will be bright.

“I believe that the long-term future of the human race must be in space,” said Hawking, who is almost completely paralyzed by the illness ALS.

“It will be difficult enough to avoid disaster on planet Earth in the next 100 years, let alone 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 is one of the few scientists known to a wide audience outside academia thanks to his best-selling books, a guest spot on “The Simpsons” and an ability to clearly explain the complexities of theoretical physics.

He has 12 honorary degrees, was awarded the CBE in 1982 and since 1979 has been at Cambridge University’s Department of Applied Mathematics and Theoretical Physics, where he is Lucasian Professor of Mathematics — a post once held by Isaac Newton.

Speaking at Cambridge’s Centre for Mathematical Studies, he said: “I see great dangers for the human race. There have been a number of times in the past when its survival has been a question of touch and go. The Cuban missile crisis in 1963 was one of these. Video Watch the interview in full »

“The frequency of such occasions is likely to increase in the future. We shall need great care and judgment to negotiate them all successfully.

“But I’m an optimist. If we can avoid disaster for the next two centuries, our species should be safe, as we spread into space.”
