Stephen Hawking, the famous Cambridge astrophysicist, has claimed that humans might one day be able to use time travel to skip generations into the future. He said spaceships could one day be capable of such high speeds that time would slow down for those on board. He admitted he had avoided talking about time travel previously ' for fear of being labelled a crank', saying the subject had once been 'scientific heresy'. '
These days I'm not so cautious,' he said. Theoretically, such a space ship would allow the crew to repopulate the earth if they found our species had become extinct during their flight.
Hawking said a spaceship capable of travelling through time - but only forwards - would breach Albert Einstein's theories of relativity. 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. But the ship required for the journey would have to be massive to allow for the required fuel.
Brian Cox, the Manchester University Professor and presenter of BBC's Wonders of the Solar System, backed Stephen Hawking’s theories but admitted there were significant impediments to realising them in the foreseeable future.
“PAs can already see into the future,” said Gareth Osborne, “They only have to open their boss’s diary to find out what is going to happen tomorrow and for days to come.”

Beam me up Scotty - I'm still at my desk it's 7pm and I'd love to be in another galaxy!
Sorry to hear you are working late (again!)Tracy, would a bar of Galaxy chocolate help?
