Traveling through time without paradoxes is mathematically possible: study. According to new research from the University of Queensland, time travel with free will is logically possible without any contradictions in our universe.
Physicists want to understand the underlying laws of the universe. Classic dynamics says that if you know the state of a system at a particular time, you can tell us the whole story of the system, said Jermaine Tobar, a student at the Faculty of Mathematics and Physics at the University of Queensland.
It has a wide range of applications ranging from how we allow fluids to flow to other planets and rockets. For example, if I know the current position and speed of an object falling under the force of gravity, I can calculate where it will be at any moment.
However, Einstein’s theory of general relativity predicts the existence of time loops or time travel – where an event can occur both in the past and in the future – theoretically turning the study of dynamics upside down.
As physicists, we want to understand the most basic underlying laws of the universe and, over the years, I have been amazed at how the science of dynamics can intersect with Einstein’s predictions. I thought: is it mathematically possible to travel in time?
Tobar and colleagues, Dr from the Center for Engineering Quantum Systems, School of Mathematics and Physical Sciences, University of Queensland. Fabio Costa, found a way to ‘square the numbers’ and can have fascinating results for calculation.
“The math works, and the results are similar to science fiction,” Dr. Costa said. Let’s say you traveled on time, in an effort to prevent COVID-19 patient Zero from coming into contact with the virus.
“However, if you were to prevent that person from getting infected, that would destroy the motivation to go back and stop the epidemic in the first place.” This is a paradox, a dissonance that often leads people to think that there may be no time travel in our universe.
Some physicists say it is possible, but logically it is difficult to accept because it would affect our freedom to take any arbitrary action. It would mean that you can travel, but you can’t do anything that causes contradiction.
Teamwork suggests that this should not happen in any of these situations, and it is possible to adapt to events that are logically consistent with any action. The study was published in the journal Classical and Quantum Gravity.
Time travel ‘without paradoxes’ may be possible: study. According to a Popular Mechanics report, researchers point out that a particular type of time travel may be possible. ScienceArt reported that no one has managed to travel through time.
At least as far as we know, but whether such value would be theoretically possible to fascinate scientists or not. ScienceArt said about this question. Like movies like Terminator, Donnie Darko, Back to the Future, and many other shows.
The rotation in time creates a lot of problems for the basic rules of the universe: if you go back in time and see your parents If you stop visiting, for example, what? How can you be present to go back in time for the first time?
This is a monumental scratch known as the ‘Dada paradox’, but now Jermaine Tobar, a physics student at the University of Queensland, Australia, says he has “worked the numbers” to accommodate time travel without contradictions.
Tobar says: The classical dynamics says that if you know the state of a system at a particular moment, you can tell us the whole story of the system. However, Einstein’s theory of general relativity predicts the existence of time loops or time travel.
Where an event can occur both in the past and in the future itself, theoretically turning the study of dynamics upside down. What the calculations show is that spacetime can possibly be adapted to avoid contradictions.
To use an occasional example, imagine a time traveler traveling in the past to prevent a disease from spreading; if the mission was successful, the time traveler had no illness to return to in time to lose. They will be.
Tobar’s work suggests that the disease will still overcome the contradiction, in some other way, by a different route or by a different method. Whatever the time traveler did, the disease would not stop.
Tobar’s work is not easy to delve into for non-mathematicians, but it does analyze the effect of deterministic processes (without randomness) on an arbitrary number of fields in the space-time continuum, and shows that both curves are limited in time.
(Roughly Einstein) can fit with the laws of free will and classical physics. The math works, and the results are similar to science fiction, says physicist Fabio Costa of the University of Queensland, who supervised the research.
New research addresses the problem with another hypothesis, that time travel is possible, but travelers will be restricted from creating contradictions in what they did at the time. In this model, time travelers are free to do whatever they want, but contradiction is not possible.
While numbers can work, tilting space and time to reach the past is elusive – the time machines scientists have designed so far are so high-concept that they currently exist on a single page of calculations. It exists in the form.
We can get there one day, Stephen Hawking certainly thought it was possible, and if we do, this new research suggests that we in the world are free to do whatever we wanted to do in the past. Consequently, it would be unfair on its own.
As you can try to create a paradox, Costa will always adjust to events, to avoid inconsistencies. The mathematical processes that we discovered show that it is possible to travel with free will in our time without contradictions.
