Slashdot has a post entitled Stephen Hawking Warns Against Confining Ourselves To Earth.
Stephen Hawking, one of the world’s greatest physicists and cosmologists, is once again warning his fellow humans that our extinction is on the horizon unless we figure out a way to live in space. Not known for conspiracy theories, Hawking’s rationale is that the Earth is far too delicate a planet to continue to withstand the barrage of human battering. ‘We must continue to go into space for humanity,’ Hawking said today, according to the Los Angeles Times. ‘We won’t survive another 1,000 years without escaping our fragile planet.'”
It’s not just the battering from humans. Space is, fortunately, very, very aptly named. But, still, there is a lot of stuff hurtling around out there. One bad collision and we, as a species, could pretty well be done. If we can figure out how to travel to and live on new planets, we can hedge our bets.
There’s a lot of work to be done to get to that level of technology; but at the moment it seems like we’re mostly killing time anyway. Might as well get started.
