British scientists say time travel possible: the future can only go back to the past

British scientist Brian - Cox Professor in British Science Festival speech pointed out that, according to Einstein's general theory of relativity, time travel has possibilities. In theory, if we can develop a large object approaches the speed of light transfer technology, humans can let the "Doctor Who Season 7 DVD" description of the time travel possible

Cox on the audience that according to Einstein's general theory of relativity, if an object approaches the speed of light, you can perform time travel. As the object approaches the speed of light, time will slow down, but this is limited to specific objects. In addition, the time machine can only bring to the future, but can not return to the past

According to media reports, the British scientist Brian - Cox Science Festival in the UK, said that time travel may not be as people have always thought of as just a science fiction, but has possibilities. However, time travel can only bring to the future, they can not return to the past. He pointed out that if you can develop a large object approaches the speed of light transfer technology, there might be sent to the future of human, like "Doctor" described to be.

In the British Science Festival, Cox said: "You can create a time machine do? The answer is yes." However, Cox said that time travel is one-way, Time Machine can only be sent to the next person, but people can not return to the past. This week, Cox will be in London on the theory of time travel, science lectures to commemorate the "Doctor" 50th anniversary. November 23, will be broadcast on BBC Doctor Who episode "Day of Doctor". Prior to this, the BBC will broadcast a series of anniversary show, Cox's speech is just one part.

Festival to be held in Birmingham on speech, Cox pointed out that time travel can already achieved, but only a very small effect on the scale of the object. If we can develop larger objects can act on the technology, there may be sent to the future of human, like "Doctor Who" as described in. However, this technology is not yet exist, even if there is, we can only make people go to the future, and can not return to the past.

Cox said: "You can go ahead, in the future world freely." That, "Back to the Future" series of films in Maadi - Mike Fry can go to 2015. However, he did not like the movie back in 1985 or 1955. Cox said: "If you move fast, your clock relative to the rest of the people who turn slower, if you can be close to the speed of light, turn your clock speed will be very slow, you can go to the next 10,000 years. "

This theory builds on Einstein's theory of general relativity. General relativity that if an object is close to the speed of light speed, you can travel in time. As the object approaches the speed of light, time will slow down, but this is limited to specific objects. For example, fly across the Atlantic time experienced slower than the people on the ground. Cox said: "According to general relativity, in theory, you can do it. Need to make time travel wormhole. Wormhole is a shortcut through time and space, but the vast majority of physicists were skeptical. Hawking proposed timing protection conjecture our understanding of physics still not deep enough, which means that the wormhole is not stable. "
