Possibility of the impossible: travel to the past and the future.

The ability to move in time to look into the future and change the past, or simply to experience pleasant moments again, centuries worried inquisitive mind of man. But today, scientists are in place so far all attempts to find a reasonable answer to the actual question of how you can teleport in so unstudied substance as time, relying only on the claim that there is no proof you can not move in it. Albert Einstein mathematically proved that time travel is possible when the object faster than the speed of light (3 * 108 m / s).
A black hole, according to science, has enormous power of attraction, and, on this basis, while near its center runs very slowly. That is all you need to travel in time - this is just a temporary move from the field of the Earth at the time of the black hole in a matter of seconds. An alternative way of moving through time and space - the use of so-called wormholes. According to quantum physics, it is possible to move into the past or future, to jump from the Earth (or any other entry points) to infinity galaxy or universe. The problem is that the wormhole is too small for the passage of people, so the first task of this generation will be the science of energy, which will expand the walls of the hole. Further, it is impossible to get "much anyhow": the "one" side, you should see the arrival, and at the same portal should be kept open. We conclude that the return to the past, which does not have this very point of arrival, it becomes impossible. Modern scientists have "fun" trying to send a photon in the past, and then change its polarization.
Recently formulated a theory was the idea of ​​Bella that all points of space have instant communication, but to be able to transfer it to the subject does not have the energy. In other words, to move in the blink of an eye can still only information.
So how do scientists need to contrive to finally get to another time, when you want? Of the most common theories of the conclusion is the following: either learn a speed greater than the speed of light, or to reproduce the energy is so strong that it can push the gravity field, opening the gates to other times and universes.
