Hawking on the future of mankind
Found via the RDFRS.
To mark his 70th birthday, physicist Professor Stephen Hawking answered a selection of questions from listeners to Radio 4's Today Programme.
Topics ranged from the origins of the universe to the prospects for extra terrestrial life and the impact on Einstein's theory of relativity should neutrinos be confirmed to travel faster than light.
It seems clear that Professor Hawking believes we we will have to colonise space if we are to avoid catastrophe, but he is upbeat about the prospects for self-sustaining colonies on Mars and believes the human race will eventually spread out across the far reaches of the universe.
Finding intelligent life elsewhere in the universe, he says, would be the greatest scientific discovery ever, but he is not optimistic about the likely outcome.
