Can time travel be done? Although this question may be imaginary to ordinary people, physicists have been looking for answers to this question for many years. On a practical level this seems a far-fetched science for science, but theoretically (theoretically) time travel has been proven possible. A scientist with his student has created a Mathematical Model that proves time travel is theoretically possible.
is the most difficult challenge in all such theories (theoretical views). Dr. Fabio Costa of the School of Mathematics and Physics at the University of Queensland explains this study, "Suppose you travel time and try to reduce the number of Covid-19 patients by stopping the spread of the virus. If you prevent the first patient from getting infected, you will go back and stop the epidemic, along with the motivation that you want to go back in time. "
Costa says this is a contradiction. There are such inconsistencies, due to which many people start thinking that the journey of time is not possible in our universe. Some physicists say that this is possible, but logically it is difficult to accept because it will affect our freedom to do our voluntary work. "
This means that you can travel time, but you can not do any action that causes any contradiction. That is why till now it was believed that the journey of contradiction free time is not possible. Dr. Costa, together with one of his undergraduate students named Jermaine Tobar, has created a mathematical model that proves that paradoxical free time travel is theoretically possible.
In this study published in Classical and Quantum Gravity, Tobar has told that by knowing the state of a system at a particular time, we can get to know about the entire history of that system. For example, by knowing the current position and velocity of an object falling freely below the effect of gravity, we can calculate at what time it will be.
But Einstein's general theory of relativity presupposes the existence of a loop or time travel, where an event itself can occur both in the past and the future. But this is the main thing that dismisses dynamics.
According to current science, both theories cannot be right simultaneously. Tobar says that he remained confused on this subject for years that how motion science can keep pace with Einstein's projections. He used to wonder whether time travel is possible or not.
One answer to this question could have been a unified theory. The theory that harmonized traditional kinetics and Einstein's theory of relativity. Working in the same direction, Tobar and Dr. Costa came up with new studies and claimed that they had achieved the method of aligning it.
According to Dr. Costa, these calculations can prove very important for science. He said that mathematics was investigated and the result turned out to be something of a science fantasy. The arithmetic of this research is complex, but it points to a very fundamental possibility. Travel at such a time that no contradiction will arise from any work. Researchers say that this will also be able to correct events with some logical tasks.
Tobar explains with the example of Covid-19 that no matter how much you try, the infection of Covid-19 will not be stopped because if you prevent it from happening in a patient, it will happen to someone else.
According to Tobar, no matter how many contradictions arise. Things will change themselves accordingly so that there is no inconsistency with the universe. In this way, time travel that can be done with our minds in our universe is possible.
