Scientists prove that time travel is real under one condition

It became known that time travel was recognized as possible by one physicist, but only under one condition.

Barak Shoshany, an assistant professor of physics at Brock University, has published an entire paper recognizing the possibility of time travel. According to the physicist, travel is possible only in one case – if the traveler goes to parallel timelines. “Have you ever made a mistake that you want to correct? Correcting mistakes from the past is one of the reasons we find the concept of time travel so fascinating. But is time travel really possible in our universe, or is it just science fiction?” Barak Shoshani started his article with these words.

According to Barak, there are currently two unsolved problems that hinder time travel. The first problem is practical and has to do with exotic matter, that is, matter with negative energy, which is necessary for time travel. It is known that all matter in the universe is positive. The negative cannot be found just like that, it has to be created. Theoretically this is possible, but in small amounts. At the same time, Barak Shoshani admits that humanity has so far been limited by current knowledge and technology. In the future, other solutions may be found that allow time travel without the use of negative energy matter.

Another problem is the paradoxes that time travel defies logic. Barak cites the paradox of consistency as an example. According to him, if an event occurs that changes the past, then this change in turn prevents the event, making it necessary to change the past. For example, you cannot go back in time 5 minutes before your trip and destroy the time machine, because this event does not allow you to go to the past. The physicist notes that it is precisely because of such paradoxes in science fiction films that usually heroes are forbidden to change the past a lot and meet themselves, so that some kind of paradox does not take place. However, the paradox itself is only a theoretical concept indicating the impossibility of a theory. Time travel in this case.

Barak Shoshani also spoke of several hypotheses built around time travel. Stephen Hawking, for example, came up with the conjecture of the defense of chronology, in which he argued that time travel is impossible. And Igor Novikov came up with the principle of self-consistency, according to which time travel is possible, but the past cannot be changed.

According to Barak’s new article, time travel is possible and does not present any problems and paradoxes. But everything only works if the traveler enters an alternate or parallel timeline. In this case, you can do whatever you want, as everything is done in this timeline and doesn’t affect the main timeline from which the time traveler arrived. Shoshani notes that he and his students are currently developing a new theory of time travel that will be compatible with Albert Einstein’s general theory of relativity.
