Top British Physicist: Time Travel to the Future PossibleSubmitted by Bob-45 on Sun, 09/15/2013 - 23:58

British physics superstar Professor Brian Cox has gone on the record to say that time travel ispossible. Unfortunately, there’s a huge caveat to his claim: if you were able to achieve this feat, you’d only be able to travel into the future never to return. Why? Traveling into the past is impossible. Possibly.
The idea of mono-directional time travel is a slap in the face for most science fiction storylines,but fortunately for Marty McFly there’s no risk of accidentally sleeping with his mother from 1955 in this scenario. However, zooming around on hovering skateboards in the future is totally plausible. Maybe.

Cox pointed out this little trick of physics at a speech at the British Science Festival while discussing the merits of Doctor Who’s TARDIS, but it probably isn’t news to anyone with a basic knowledge of how Einstein’s theory of Special Relativity works. Although the UK national press seems to think otherwise.
