Here's how you jump in the past
An Italian physicist has constructed a theoretical model. Who will be evaluated by NASA probe Gast
Who would not like to go back in time? Maybe you want to correct errors or relive good times? This possibility is currently in the repair of the only superhero movie could become reality: the laws of physics allow it. Among those who theorized the existence of galaxies in space-time tunnels for use with a hypothetical "machine of time "is Fernando De Felice, University of Padova
. The physicist has put together various cosmic phenomena, mathematical model that involves building a step back in time through the naked singularities that are found in galaxies.
EXCEPTIONAL - But what is a naked singularity? "When you form a black hole for the collapse of a star under the action of its gravitational field inside the black hole creates a singularity, ie a region where abnormal situations occur - said De Felice -. The light captured by the black hole prevents us to observe this singularity. And 'as if it were to veil. However, there are naked singularities, not sealed from light and therefore visible. Naked singularities are obtained from information on its gravitational field, very complicated, where you experience exceptional phenomena such as time reversal. "
RETURN TO THE PAST - According to the scientist in the singularity particles move in the opposite direction with respect to time, as predicted by Einstein's theory of relativity. "Simply put, the second in our lives are moving forward: 1, 2, 3. For someone who is going back into the singularity: -1, -2, -3, compared to an outside observer. Put simply moving in the past. " For the moment you board a spaceship to reach these areas do not talk, we must wait for other advances in technology. "Moving at a speed much lower than that of light, the journey is impossible., Would be very long." Yet there are those who dream of a clock that ticks counterclockwise, no matter how the jump in the past may interfere with the events coming, even jeopardizing his own birth. Remember the movie "Back to the Future"? Michael J. Fox had not absolutely meet himself not to distort history.
IN THE FUTURE - Meanwhile, the most important outcome of the study by De Felice, reported by New Scientist magazine, is that we know we can check time, past and future: "I travel in the future have already been reproduced in the laboratory. Particles that travel at the speed of light are born and die in a millionth of a second, but seen by us of their existence is 10 seconds. It means that their life has spread in practice have made a leap in our future. " The transfer in the future is best explained with the twin paradox. If twins are separated: one on Earth and the other sailing among the stars at the speed of light, when the two find themselves astronaut has 20 years, the Earth 200. The twin who has traveled at the speed of light is missed in the future of his brother.
AT CERN - What if avventurasi be built in the galaxy of the singularity in the laboratory? Difficult, would be immense, a mass of incalculable. The researchers are not discouraged and are organizing to artificially produce a small black hole (and its singularities) with large accelerators like the LHC (Large Hadron Collider) under construction at CERN in Geneva. "Re-create a black hole? It 's a moot point - said De Felice -. These quantum objects do not behave according to classical laws of physics. I do not know if they can actually shape it. "
PROBE - Maybe GAST NASA probe to confirm the theory of De Felice. GAST will start next year with the aim of measuring the space high-energy flashes of light, known GRBs (Gamma-Ray Bursts). "In my model if you form a naked singularity, then there exists a trajectory of time reversal. And where both conditions occur GRBs are formed, the high-energy flashes of light in a very short moments. Without one of the three components of the model fails. " We'll see if De Felice's right.
