A scientific study revealed paradoxes at the heart of time travel, and the possibilities for humans to be able to go back, an idea that has always been trapped in science fiction, and does not go beyond Hollywood films, according to Russia Today Network.
Scientists and screenwriters alike have long been fascinated by the possibility of time travel, and many films have also shown that it can lead to all kinds of unexpected consequences. One of the main contradictions is known as the "grandfather paradox".
The scientific research was published in the “Classical and Quantum Gravity” magazine specialized in science. As for the researchers, they are physicists who want to study if it is possible to turn a person back in time. The contradiction is just any act that changes the past, as it becomes different from what it was. So, if you traveled back in time and prevented your parents from meeting, how could you be born to travel in time in the first place?

Researcher German Tobar explained: “Classical dynamics says if you know The state of a system at a particular time, this can tell us the history of the entire system However, Einstein's general theory of relativity predicts the existence of time loops or time travel - where an event can be both in the past and the future itself - theoretically turns the study of dynamics on its head The researcher used the example of the coronavirus pandemic, to explain his dense calculations. If a time traveler set off into the past to prevent the disease from spreading, and if he succeeded in doing so, there would be no disease to bring him back to eradicate it. However, Tobar's work found that the virus still got away in another way. No matter what the time traveler did, the disease would not stop, so the paradox goes away.
Deep theoretical work focuses on the effect of deterministic processes on an arbitrary number of regions, in the space-time continuum. Tobar showed how closed, time-like curves (which were predicted by Albert Einstein) could fit in with the rules of free will and classical physics. "The mathematics has been validated - and the results are the stuff of science fiction," said physicist Fabio Costa of the University of Queensland, who supervised the research. ".
