Living in Space
Professor Stephen Hawking reckons humans will have to head into space to find a new home and survive in the next 200-500 years.
He says the threats now facing Earth are "too big and too numerous, and the only places to go are other worlds."
He was speaking at an event in Norway, and he said nuclear-powered light ships or "some new form of energy" could carry craft to Alpha Centauri, Earth's nearest star system.
He also thinks that "spreading out may be the only thing that saves us from ourselves. I am convinced that humans need to leave Earth."#
Personally, I do think man will kill this planet one day.
Do you agree with the Professor, and can you ever envisage life elsewhere?
