Paul Auster, in one of the passages of his novel The night of the oracle (Seix Barral), it proposes the possibility of traveling through time. The subject is presented to the protagonist when he accepts the commission to write a film script to adapt the famous novel by H. G. Wells, The time Machine; a science fiction story where a scientist of the late nineteenth century manages to move to the year 802,701.

The protagonist of Auster's novel thinks that if someone had the capacity to invent a machine that would take us to the future, with that same logic, the people of the future could do the same, inventing a machine to move to the past. In his musings, he comes to think that if people could go back and forth through the centuries, both the past and the future would be full of people outside their time.

Every time we read a novel where time travel is the central theme, as in the story of HG Wells, we wonder what is true in all this Are occurrences of novelists and people with an excess of imagination or really can we travel in time?

We are going to try to reveal it because after Einstein formulated his theory of relativity special, our understanding of space and time will be modified and, with it, also the trips through time. Undoubtedly, the theory of relativity formulated by Einstein will give us the key to make the journey through time, since this trip is conditioned by light and space, being that to travel to the past you have to overtake a ray of light and to travel to the future you have to pursue it.

According to this theory, the passage of time is not immutable or absolute, it depends on the movement. In short, the theory of special relativity goes to say that you can travel to the future and, for that, it is enough to go on a trip and return after a while. This has been proven experimentally with an atomic clock that, after going around the world on an airplane, was compared with another one with which it had previously been synchronized.

Einstein, to develop the theory of special relativity, proposed the example of the two twins. The first one enters a spaceship and makes a long trip at speeds close to the speed of light while the other twin stays on Earth. On the way back, the twin who returns from the trip is younger than the twin who waits on Earth. In this case, the time of the twin that travels has passed more slowly than the time of the earthly twin so that the latter, ages faster.

Because of this, and with the help of current technology, we can travel to a future so close that it is only a few hundredths of a second away from our present, so that we can know the result of a football match shortly before it ends. , but, with such a small margin of time that it does not allow us its success in the pool. Traveling to the past is more complex and is only possible with the mind, but never with the body. According to the second Principle of thermodynamics, the aging is irreversible although in the space there are paths that lead to the past, "space shortcuts" by which we can overtake a ray of light.

As Paul Auster points out in his novel, if a person could travel through time, time would cease to exist as an entity of his own. With this issue, Auster takes us to the common place of the anthropic principle, the same principle that proposes that if there were a universe that would allow time to move, we would be facing a universe where intelligence would not evolve because it would be confusing, not to say impossible, record the events that have taken place or are happening.

"Once the people of the future made their influence felt in the events of the past and the people of the past began to influence the events of the future, the nature of time would change," writes Paul Auster in The night of the oracle, taking us to the fields of scientific fiction to make us understand that, with a future that knew how to return to the past and with a past that knew how to reach the future, time, as we know it, would cease to exist.

The stone ax it is a section where Montero Glez, with a will to prose, exercises his particular siege on scientific reality to show that science and art are complementary forms of knowledge.
