"It's time to abandon Earth, warned the world's most
famous theoretical physicist.

In an interview with website Big Think, Stephen
Hawking warned that the long-term future of the
planet is in outer space.

"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," he said."
