Scientists believe that time travel is not possible only in science fiction novels, but also in real life. Of course, for most people, this area of science seems rather vague not only from a scientific, but also from a moral point of view.
Time has an arrow that moves steadily forward. Changing this order of things can lead to violations causal relationships. No one knows how it can The intervention in the past is displayed today. Maybe, even the smallest action in the past can ruin that the world we live in. But despite the danger, many of us I would like to make such a trip.
Theoretically, so that an object with mass can jump into the past, he needs to develop a speed exceeding the speed Sveta. However, Einstein’s theory of relativity says: nothing, having a mass, cannot move in a vacuum faster than light!
Physicist Robert Nemiroff sure that this statement is not entirely accurate. The scientist believes that technically such a speed to develop can. This requires energy, the total value of which It will be just huge, but it is easy to calculate, using the well-known formula E = mc2. But a massive object that can overcome the speed of light, will infinitely increase its speed and already can never slow down, and therefore stop.
At the moment, it is impossible to create a spacecraft that could overcome this line. However, hypothetically, we can understand the essence of the process of traveling back in time, including fantasy. Robert Nemiroff proposes to introduce a certain spaceship, which starts from Earth at a speed five times higher light. After ten light-years of rotation in the Earth’s orbit, our the ship returns to its launching pad on Earth again.
And so, at the time of the launch of the ship and throughout its journey an outside observer will be able to record an interesting fact: from our hypothetically super-fast ship will begin to separate it exact copy. It will look as if our ship “gives birth” to its copy, and that in turn rushes in pursuit of “original”.
This copy will follow the same route as the original, literally repeating his every maneuver in space. And so, after return of our ship to Earth by its phantom, repeating the message let following, in 10 years will return to the same point in space.
What will happen? According to Dr. Nemiroff, both ships, duplicating each other to the last atom, annihilate.
It would seem that such an example gives little to understand the general quantum theory and theory of relativity. However, he is very indicative. He demonstrates that time travel theoretically possible for bodies having mass if their mass is converted to wave energy. This will happen duplication of a massed original (moving at a speed close to the speed of light) its copy, without mass. Because the a copy converts mass into a wave structure, its speed can exceed light and travel in time.
In other words, under certain conditions, the same object could theoretically be at different points in space in one and the same time. That is, the past of the original may well become the future for a copy of it.
