Time machine's are possible

Time machines similar to Doctor Who’s Tardis are possible, Professor Brian Cox said in a speech at the British Science Festival.

“Can you build a time machine?” said Professor Cox, “The answer is yes.There’s just one, tiny problem, if you can build a machine capable of time-travel, you can only travel into the future. You can’t come back." 

To “travel” forward in time, you simply need to accelerate to speeds close to the speed of light, Cox says - as you get close to that speed, time slows down, but only for you, according to Einstein’s Theory of Special Relativity.

Professor Cox also suggested that research at the LHC might uncover extra dimensions - thus, perhaps finally explaining how the TARDIS is bigger on the inside. Professor Cox , a Dr Who fan, is to deliver a 60-minute speech on Dr Who to be screened by the BBC on November 23 - tackling questions such as extraterrestrial life, travelling to other dimensions and time travel.
