This isn’t the first time the theoretical physicist has suggested that humankind must leave Earth in order to survive.

In January, during a BBC Reith lecture, Hawking said humankind is inching closer to demise, and it’s our fault.

He said it’s inevitable that a disaster, possibly of our making, will strike the planet.

“By that time we should have spread out into space, and to other stars, so a disaster on Earth would not mean the end of the human race,” he said during the BBC lecture.
