Should it be possible to travel into the past, questions would arise as how the paradoxes are to be avoided which may arise in this context from the violation of causality, such as the Grandfather paradox. .. When they got home, everyone on Earth would have aged five years more that they had.". Also, the human body would not be able to withstand time travel at all, as travelling at nearly the speed of light would kill you. Another possibility would be travelling at the speed of light, a constant, finite speed of 186,000 miles per second. But, "even if it turns out that time travel is impossible, it is important that we understand why it is impossible," he says.
Time travel: four ways in which it could be possible. Method Not Allowed .. Bi vit gc . Since the observers evaluate the temporal order of the events of A and B different, the tachyon moves from the past to the future for all participating. "The basic idea if you're very, very optimistic is that if you fiddle with the wormhole openings, you can make it not only a shortcut from a point in space to another point in space, but a shortcut from one moment in time to another moment in time," Professor Brian Greene, a prominent string-theory physicist, told Live Science. Einstein's theory of relativity suggests that it may be feasible to travel backwards in time by following a "space-time path" that doubles back and returns to its own starting point in space, but at an earlier time, NDTV news reports. "Einstein's general relativity and quantum mechanics." Using both of these theories, scientists have suggested several ways they believe time travel could be possible at least theoretically.
