WELL, HE’S SAID IT BEFORE BUT HE’S STILL RIGHT: Human survival depends on space exploration, says Stephen Hawking.

Stephen Hawking says the colonization of outer space is key to the survival of humankind, predicting it will be difficult for the world’s inhabitants “to avoid disaster in the next hundred years.”

The renowned astrophysicist explores some of the most remarkable advancements in technology and health with the new U.K.-Canadian series “Brave New World With Stephen Hawking,” debuting Saturday on Discovery World HD.

Before its premiere, he discussed the earth’s most pressing concerns in an email interview with The Canadian Press from Cambridge, England, declaring space exploration to be humankind’s most urgent mission.

“We are entering an increasingly dangerous period of our history,” said Hawking, who has Lou Gehrig’s disease, leaving him almost completely paralyzed and unable to speak.

I agree.
