A Physicist Came Up With Math That Shows 'Paradox-Free' Time Travel Is Plausible

Scientists are fascinated by the question of whether or not it is possible to travel through time.

If you go back in time and stop your parents from meeting, how can you possibly exist in the universe?

Germain Tobar, a physics student at the University ofQueensland in Australia, worked out how to square the numbers to make time travel viable without paradoxes.

"If you know the state of a system at a particular time, this can tell us the entire history of the system," said Tobar.

Einstein's theory of general relativity predicts the existence of time loops or time travel where an event can be both in the past and future of itself.

The calculations show that space-time can change to avoid paradoxes.

Imagine a time traveler going back in time to stop a disease from spreading if the mission was a success.

The disease could still escape through a different route or a different method according to Tobar. The disease wouldn't be stopped regardless of the time traveler's actions.

The influence of deterministic processes on an arbitrary number of regions in the space-time continuum is looked at by Tobar in his work.

The results of the research are the stuff of science fiction, according to the physicist.

There are two people, Germain Tobar andFabio Costa. There is a person who says, "Ho Vu."

It was found that time travel is possible but that time travelers would be restricted in what they did to stop them from creating a paradoxes. Time travelers have the freedom to do what they want, but not paradoxes.

The time machines that scientists have devised so far are so high concept that they only exist as calculations on a page.

According to new research, if we get there one day, we would be free to do what we wanted to the world in the past.

Costa said that the events would always adjust themselves to avoid any inconsistencies.

There is a range of mathematical processes that show that time travel with free will is possible in our universe.

The research was published in two different books.

It was published in September 2020.
