Human race 'must colonise space or face extinction', warns Stephen Hawking

Stephen Hawking has warned that unless the human race colonises space within the next two centuries it will disappear forever.
The famous astrophysicist says that our only chance for long-term survival is to move away from Earth and begin to inhabit new planets.
In an interview with website Big Think, Hawking said he was an âoptimistâ but the next few hundred years had to be negotiated carefully if the human race is to survive.
Earlier this year Hawking he said that a spaceship capable of travelling through time - but only forwards - would breach Albert Einstein's theories of relativity.
This means that humans might one day be able to use time travel to skip generations into the future.
Having taken six years to reach its full speed of 98 per cent of the speed of light (650million miles per hour), a day on board the ship would be equivalent to a year on Earth, he said, allowing those on board to reach the edge of the galaxy in just 80 years.
