Celebrated physicist Professor Stephen Hawking has said that he believes we may face nuclear armageddon.

Hawking recently answered questions on BBC Radio 4 as part of a programme celebrating his 70th birthday. "I think it is almost certain that a disaster, such as nuclear war or global warming, will befall the earth within a thousands years," he said. "It is essential that we colonise space. I believe that we will eventually establish self-sustaining colonies on Mars, and other bodies in the solar system, although probably not within the next 100 years."
