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.
This is not the first time Hawking has warned of impending planetary doom. In 2006, the physicist warned that Earth was at an ever increasing risk of being wiped out. And lately, Hawking has become quite outspoken.
