A physics student admitted that time travel is possible without creating paradoxes

Despite the fact that time travel is currently not possible, scientists have been arguing for many years that they are impossible without the occurrence of paradoxes. In particular, one of them is the famous "grandfather paradox", the essence of which is that if in the past the parents of a time traveler do not meet, then he will not be born.

However, physics student Germain Tobar from the Australian University of Queensland admitted that time travel can take place without paradoxes, as stated in the publication in Classical and Quantum Gravity. He noted that Einstein's general theory of relativity anticipated the existence of time loops and time travel, implying the existence of events in the past and future. As Tobar pointed out, the space-time continuum can adapt to prevent paradoxes.

The physicist gave an example that if a time traveler goes to the past to defeat the disease and succeeds in this, then in the future he will not have the motivation to return to the past. Tobar admits that the disease will arise in any other way, thereby eliminating the paradox, so the actions of the traveler will not have an effect.

He hypothesized that time travel is possible, but its participants will be limited in their actions in the past to prevent the occurrence of paradoxes. In this case, according to Tobar, paradoxes will be impossible, and the travelers themselves will be free to do what they want to a certain extent.
