Scientists Propose New Theory to Solve Time Travel Paradox and Enable Time Travel

A New Theory Suggests Time Travel Might Be Possible Without Creating Paradoxes

Germain Tobar is a physics student from the University of Queensland who has come up with a theory that could enable people to travel through time in the absence of temporal paradoxes.

Tobar’s mathematical approach further theorized that space-time is capable of undergoing corrections as a natural phenomenon, hence even if one were to travel back in time and change the past, the universal laws of space-time are bound to adjust in order to set right the disrupted time-line.

The sentiments presented in this theory are charming and manage to provide a new look at time loops and free will as Einstein foresaw. While the mathematics is solid, unraveling the real-world wrinkles necessary to make time travel a reality is still far in the future.

Time travel is a concept that often cross our minds and this article is here to amaze you by revealing how the existence of time travel can be real without any paradoxes. While it is probable that no one has actually gone through time travel at least not in the way that has been depicted in movies and tv series, the possibilities hold interesting theories for scientists. It is interesting to note that with reference to movies like The Terminator, Donnie Darko and Back to the Future, time traveling may pose a number of issues to the universe and its basic laws. For example if you killed your parents before they met how can you go back in time to kill them?

This has remained a puzzle to many, this is commonly referred to as the “grandfather paradox” but Germain Tobar, a physics student at the University of Queensland, Australia has claimed to have cracked the nut, making time travel possible in the theoretical aspect.

‘Classical dynamics is the theory that stipulates that if you can establish the condition of a system in the current moment, you can be able to decipher its past,’

Tobar further expounds. However, as Talia H. translates it in The New Yorker, “General relativity also indicates the possibility of time loops or time travel, when an event exists in both the past and future of the past, theoretically raising issues concerning dynamics.

If there is such a thing as space-time or one can calculate on it, then calculations done by Tobar show that space-time could correct itself to negate paradoxes.

For instance, if I can go back in time with my DeLorean, I would do it in order to prevent the spread of a disease. Where successful there would be no disease for the traveler to return home and avert. According to Tobar’s study, the disease would re-emerge in a manner that would bypass the paradox. Thus, taking any action the spread of the disease would not be stopped completely.

What I know is that Tobar’s work is mathematically detailed, nearly indecipherable for anyone not skilled in mathematics, however, it also explores deterministic behavior (no stochastics) in different areas of space-time. It also shows how one might get closed timelike curves, which Einstein prescribes, and still stick to principles of free will and classical physics.

Says Costa, ‘The math works, and the outcomes are something that feels like science fiction. ’

The new study addresses the issue with another hypothesis: that time travel is possible however being a time traveler comes with limitations that one cannot do anything that will make a paradox to occur. This one, unlike all the previous ones, allows time travelers to behave in any way feasible with their unique status, while at the same time denies the possibility of paradox.

On the mathematical level this may be all well and good, or logical; but to twist space time and travel back in time – that is indeed a trick. All presently envisioned time machines to date are still preconceptions of science and science fiction.

There might come a time in the future when humanity will be able to travel through time – Stephen Hawking once said that it was possible – and if we do, this line of research indicates that we may be able to change the past at will and the universe will make sure that everything ends up that way.

“As much as you would wish to construct a paradox, the arrangement of occurrences will always ensure that there is no incongruity,” notes Costa. ‘The mathematical results lend us the fact that free will time travel is logically feasible in our universe and does not breed paradoxical effects.
