Human Survival Depends On Space Exploration, Says Hawking

thomst writes "The Winnipeg Free Press posts a story by Cassandra Szklarski of the Canadian Press about an email interview with Stephen Hawking in which the astrophysicist and geek hero opines, 'Our only chance of long-term survival is not to remain lurking on planet Earth, but to spread out into space.' The story also covers the upcoming Canadian debut of Hawking's new TV series 'Brave New World With Stephen Hawking,' and his excitement about ongoing work at the Perimeter Institute in Waterloo, Ont. investigating quantum theory and gravity."

    Without gravity, we'd die.

    No.

    Without WEIGHT, we'd die. Not quite the same thing.

    A spin habitat will do nicely to provide weight (and, if looked at in the proper general-relativistic way, gravity), without the need for large masses and the other inconveniences of gravity.

    Garbage disposal in transit is a problem, stuff you throw out the airlock follows you to your destination.

    How so? Assuming you throw it at greater than the escape velocity of your craft (how big is this craft?) surely it will continue to diverge from your path at the same velocity?

    Once, I would have written it off to deja vu and went on with my life. But the same article, 3 times? I might be human, but my memory is not that terrible, Slashdot!
