Hawking has theorized that the only way to save the human race is through outer space travel and colonization of other planets, like Mars.

The scientist explains his theory in a new BBC documentary, "Expedition New Earth," airing in June.

"With climate change, overdue asteroid strikes, epidemics and population growth, our own planet is increasingly precarious," the BBC said in a statement about the show.

"Professor Hawking’s ambition isn’t as fantastical as it sounds."

Hawking last November predicted the planet had 1,000 years before such a disaster might strike.

His new documentary is expected to explain the new, accelerated timetable.
