New research has revealed paradoxes at the heart of time travel, making it more than just a plot of countless Hollywood movies, and mathematically possible.

Scientists and screenwriters alike have long been fascinated by the possibility of time travel. Several movies have also shown that it can lead to all kinds of unexpected consequences. One of the main contradictions is known as the “grandfather paradox”.

A contradiction is just any act that changes the past, as it becomes different from what it was. If you traveled back in time and prevented your parents from meeting, how were you born to travel back in time in the first place?

A physics student from the University of Queensland in Australia said he uncovered the mathematics behind the secrets of time and made it applicable without the contradictions.

Important research reveals how epidemics and ancient diseases spread!

Researcher German Tobar explained: “Classical dynamics says if you know the state of a system at a particular time, this can tell us the history of the entire system. However, Einstein’s general theory of relativity predicts the existence of time loops or time travel – where an event could be in the past And the future in itself – theoretically turns the study of dynamics upside down. ”

The researcher used the example of the Coronavirus pandemic, to explain his incredibly dense calculations. If a time traveler sets out to the past to prevent the spread of disease, and if he succeeds in doing so, there will be no disease that takes him back to eliminate it.

However, Tobar’s work found that the virus could still elude otherwise. Regardless of what the traveler did through time, the disease will not stop, so the paradox will disappear.

Profound theoretical work focuses on the effect of deterministic processes on an arbitrary number of regions, on the spacetime continuum. Tobar explained how closed, time-like curves (predicted by Albert Einstein) could coincide with the rules of free will and classical physics.

“The mathematics has been validated – the results are science fiction material,” said physicist Fabio Costa of the University of Queensland, who led the research.

Tobar’s study has been published in Classical and Quantum Gravity.
