Stephen Hawking: "We Won't Survive Another 1,000 Years Without Escaping Our Fragile Planet."

Après moi, le déluge, eh, Stephen?

NASA came about because humans got to a point where, even after much imagination, shall we say, they realized no one was coming to take them off this planet.

If you hold your finger out to the sky and point, your finger might be directly under Chris Hadfield - way, way, way out there. It amazes me that some little man could be hovering two hundred-seventy miles over me, turning over as though in a floating washing machine, with almost nothing between us but my ceiling, sky, and the hull of the space station. Even though I cannot see him, somehow this lack of things between us makes me feel eerily vulnerable and at peace at once.

I have faith in humanity. I think another thousand years is more than enough time. Maybe by that time not all of us will need to leave.
