Time travel is logically possible by expressing mathematics, but how can it not be done

Time travelers may be disappointed with the results.  Two mathematicians claim that the heart of travel lies at a time when there is no logical inconsistency, so it is theoretically possible for anyone to travel on time and change reality. Germain Tobar, an honors student at the University of Queensland, said in a statement, “Einstein’s theory of general relativity predicts the existence of a time loop or time travel – where an event can be both its past and future – theoretically turning the study of dynamics in its head.”  If time is only the fourth dimension, then it is natural to wonder why we cannot go through it.

Numerous science fiction writers have danced around the problems of travelers of their time, carefully changing things in ways that do not hinder their journey.
Many pointed to the so-called “grandfather paradox” that this type of travel could not take place. If at any time the traveler prevents them from meeting their grandparents, they can never be present, and therefore will never be able to resist face to face.

Tobar was inspired by the equation that Einstein created to describe the loops of this period. In Classical and Quantum Gravity, he and his supervisor, Dr. Fabio Costa, show that there is no logical need to prevent time-travelers from making trivial changes.  The solutions of this pair imply that the universe will adjust. Although the model they describe in their paper involves a simple world where billiard balls represent jumping against each other, they suggest managing more complex human environments in the same way.

“In the zero examples of a coronavirus patient, you can try and prevent the patient from becoming infected with Zero, but by doing so you will catch the virus and the patient will become Zero, or someone else,” Tobar said. Although you can change history, it will only be the way you exist and want to make a journey that avoids any catastrophe.  Similarly, Tobar told IFLScience that a person who tried to turn himself into a worm in order to travel on time could miss something, causing eye damage to the process, which could cause them not to notice the whole properly. The example of the epidemic may question potential time-travelers if this journey is worth the effort. Tobar acknowledges this but argues that the changes may be incredible but trivial.

“Alternatively, events rearrange around something that might have caused a paradox that didn’t happen, so maybe someone actually came back but the word didn’t come out.” Instead of government-run cover-ups, conspiracy theorists insisted that the laws of physics were hiding the truth. Tobar told IFLScience, if time travel is possible, we can ask in a version of the Fermi paradox, why future travelers did not come to see us, even to show the events to which they were specially invited. “While time travel is reasonably possible, further restrictions may be imposed.”

Costa told IFLScience that white paper does not directly assist in the search for quantum gravity, different structures can be applied to that search for the dynamics developed on paper.  Tobar added that this work does not provide any guidance on how time travel works. Nevertheless, it may prove effective in other ways. The quest for quantum gravity, the theory that would integrate general relativity and quantum mechanics, is the sacred grill of modern physics.
