Hawking to Take Zero Gravity Ride
An anonymous reader writes "Well-known cosmologist Stephen Hawking is preparing for a once-in a lifetime trip. His goals are for even higher ground, but right now he's readying for an April zero gravity ride aboard NASA's 'vomit comet'. His ultimate goal is to take a ride on one of Richard Branson's Virgin Galactic flights, and this is a 'test run' for that more rigorous experience. Though complex math ain't no thing for Dr. Hawking, his interests here are purely inspirational. 'Hawking says he wants to encourage public interest in spaceflight, which he believes is critical to the future of humanity. "I also want to show," he said in an e-mail interview, "that people need not be limited by physical handicaps as long as they are not disabled in spirit."'"
I was under the impression you had to have a certain level of fitness and stamina.
Maybe they figure he has nothing to lose. As long as his head is protected, so what if he breaks his spine or loses a limb: he can't use them anyhow.
Table-ized A.I.
While I respect the man, I'm a bit baffled by things like this "he wants to encourage public interest in spaceflight, which he believes is critical to the future of humanity."
The "future" covers a huge amount of time, so I'm not sure we need to take interest in space exploration *now*. If I was the one spending money, I'll put most of the credit into Drexler's style nanotechnology research, once we 'master' nanotechnology, then tackling space exploration makes sense as either:
- at best a space elevator becomes possible and space access cost are reduced a lot,
- at worst a space elevator is impossible, but the improved materials should still reduce the cost of space access a lot and the payload themselves would be lighter.
