LONDON - The affect of the new time travel the minds of scientists who are looking for, especially through the new physics, the answers, at least theoretical means. To intrigue more, in some respects, appear to be the bounds of the past, perhaps seduced by Mark Twain that he wanted to make a trip to the Middle Ages with his An American in the court of King Arthur. For researchers, in this case, however, is not a void, albeit fascinating exercise fantasy. Seth Lloyd of MIT in Boston at the head of an international group of scholars which also includes two Italian (Vittorio Giovannetti and Lorenzo Maccone) has shown a proper explanation as sophisticated, but in fact a journey back in time would be addressed. The protagonists
Compared to many other theoretical attempts made so far, Lloyd adds more credibility because it makes use of an 'effect' first ignored. Let's see how. He begins with the transporter, the most well-known thanks to Star Trek where people are transferred from one place to another instantly (in the laboratory, however, some have already been teleported photon) and by quantum mechanics. But the trick is to trigger the 'effect of the suffix "of that time, is a different way of playing cards available. Thanks to it, only the particles that were found could be teleported back in original condition, thus making a trip back in time as well.
The appeal to the strange "effect" allows scientists to bring some advantages as in the scene without running into serious problems raised by time travel so far assumed related to the theory of relativity. In this case, required a much more difficult is the deformation space of time. Secondly, around a very famous paradox known as the 'paradox of grandfather, "which imagines go back in time and kill his grandfather and what, exactly, is paradoxical because it would prevent the birth of the murderer.
But the new theoretical effort aimed to imagine a time machine hidden in fact add value and perhaps even more fascinating is that the great challenge for decades, at least since the time of Einstein, the physical torture. It is the dream of uniting with the laws of quantum mechanics and relativity to get the coveted "theory of everything ', ie a single, simple, universal law that unifies all the other simplifying the description of the world.
addition to the exciting frontier of knowledge there is also a more practical purpose. The effect of post-selection used by Professor Lloyd is the basis of research on quantum computer that you begin to see some possibilities on the horizon and when that will materialize again upset our lives. Similar information perspective, of course, was not treated in time machine that HG Wells wrote in 1885 to travel in the future will bring us up to the year 802,701. But paradoxically, if the 'effect post-selection "of Professor Lloyd worked really open both doors, those of the past and the future. It's enough, meanwhile, to run the imagination.
