In a rare interview, Stephen Hawking said to the BBC that humans must move to another solar system in order to ensure the survival of the species. “Once we spread out into space and establish colonies, our future should be safe,” he said. Hawking made a similar suggestion back in June. He believes that life on Earth could be wiped out by a nuclear disaster or a massive asteroid hitting the planet causing Armageddon with its Deep Impact. He said that, since we have no similar planets on our solar system, we would “have to go to another star” to find a suitable habitat.Before humans could even dream of such a move, we would need to develop a viable means of transportation. Hawking proposed “matter/anti-matter annihilation” propulsion. He explained: “When matter and anti-matter meet up, they disappear in a burst of radiation. If this was beamed out of the back of a spaceship, it could drive it forward … It would take a lot of energy to accelerate to near the speed of light.
