A new mathematical model proposes paradox-free time travel.

Just three of the many science fiction films that make use of temporal paradoxes to lend continuity to their plot thread are “Back to the Future,” “Terminator,” and “Trapped in Time.” There are many other films that engage in this practice. It is interesting to note that this phenomena, which is created by time travel, has not just been investigated by the film industry. For decades, physicists have been working on mathematical models that attempt to explain the nature of temporal paradoxes and the circumstances under which they could be avoided. Or take place.

However, a very creative mathematical model that represents the concept of free time travel was proposed in an article that was just published a few days ago in the scientific journal ‘Classical and Quantum Gravity’ by two researchers from the University of Queensland, which is located in Australia. in the realm of paradoxes are possible. This article takes a novel approach, and what is more important is that it offers a theoretical interpretation of a solution to one of the most significant challenges that may be attributed to time travel.

In an effort to find a solution that brings together general relativity and classical mechanics
It is one of the most significant issues that physicists have been confronted with over the course of several decades, and every once in a while, a flash of insight appears that appears to move us a little bit closer to the unification of both paradigms. The essay that was published by physicists Fabio Costa and Germain Tobar is probably only a blade of grass in a meadow whose limit we are not yet able to see. However, the mathematical underpinning of the article suggests a solution to one of the most significant challenges that time travel presents, as I said in the previous paragraph.

If you know the state of a physical system at a certain instant, not only can you describe the states it has been in in the past, but you can also forecast the states it will be in in the future, according to the classical mechanics theory. This principle underpins a significant portion of our technological infrastructure. Consider the scenario in which we throw a tennis ball from the top of a building. This is a straightforward method to comprehend what it is proposing. Through the use of classical physics, we are able to calculate with a high degree of accuracy the location that the ball will occupy at each and every moment, as well as the speed that it will be traveling along its route of down towards the ground of the street.

The fact that the General Theory of Relativity, which was introduced by Albert Einstein in 1915, advocates something completely distinct from classical physics, despite the fact that classical mechanics has been shown to perfectly fit into many of the physical events that we are able to see in our macroscopic world, stands out as a peculiar phenomenon. Furthermore, it forecasts the presence of time loops, which means that a physical system is capable of concurrently occupying two distinct states that correspond to its past and its future.

Following Einstein’s description of this concept in his General Relativity, a large number of other physicists and mathematicians, including Kurt Godel and Willem Jacob van Stockum, took up the mantle of developing it further and comprehending its implications. This concept is sufficiently counterintuitive that it is not easy to comprehend. One of them was explained in detail by Godel and van Stockum, and due to a phenomena that is referred to as a closed time curve, it is possible to carry out time travel mathematically. This possibility is put forward by the mathematical possibility of time travel.

Explaining what it is is beyond the goal of this article due to its complexity , but at least we are interested in knowing that these time curves indicate the probability that a physical system can return to the same condition from which it initially started. It is essential that we bear in mind that all of the concepts that we are developing in this article are contained inside the theoretical area, despite the fact that this occurrence is known as a full-blown time travel. In science fiction films, time travel machines are the only thing that will ever be available. Well, at least for the time being.

In the three films that make up the ‘Back to the Future’ trilogy, Marty McFly, the main character, has never been in danger of losing his life. At the very least, this is the conclusion that we are able to reach after reading the essay that was written by Fabio Costa and Germain Tobar. Additionally, the mathematical model that was proposed by these experts explains that it is feasible to travel through time without compromising one’s free will and without the occurrence of temporal paradoxes or other forms of contradictions. It is essential that we do not forget that this is a mathematical model that is restricted to the theoretical domain. This is something that we must recall once more.

Costa and Tobar have arrived at the opinion that the events that a physical system is subjected to are always readjusted in order to prevent inconsistencies. This is the conclusion that they have reached. Despite the fact that we are making an effort to construct a grandfather paradox, which poses the question of what would occur if we were to travel back in time and kill our grandfather before he became acquainted with our grandmother. Under these circumstances, our father would not have been created; neither will we, and the impetus that drove us to go through time will be null and void, resulting in a contradiction or a temporal inconsistency.

The example that Costa and Tobar have used to explain their discovery is quite simple to comprehend, and as a result, I propose that we make use of it. Imagine for a moment that we possess the technology that would allow us to travel through time. We make the decision to utilize this technology to travel back in time a few months, travel to China, and prevent patient zero from becoming infected with the coronavirus. Our goal is to ensure that the pandemic does not take place. The reason that motivated us to go through time would be eliminated if we were successful, which would result in the emergence of a paradox.

The mathematical model that these researchers developed provides a solution to this discrepancy by enabling the time traveler to keep their free will and carry out the actions that they ought to carry out, but without completely reversing the event that prompted them to travel through time. Within the context of the example that we presented, the initial patient zero would not become infected; however, the system would adapt itself around us in order to keep the equilibrium regardless of what we did. In the event that the pandemic strikes at some point in the future, the initial patient zero could be replaced by another individual. Perhaps even by the time traveler himself, who, in his efforts to avoid infection, might wind up infecting himself in the process of traveling through time.
