Is Time Travel Possible?

Everyone is currently running in the future, always moving forward at the same speed. Science says that humans can move about at a rate of one second per second, whether they want to or not. Hey, here is an ice breaker, time can change speed.

When Einstein introduced Special Relativity in 1905, the realization that all the great things in the universe must go on overtime was one of its most remarkable effects. These statistics and the theory itself do not preclude the idea of ​​time travel, although Einstein made many attempts to ensure that going back in time was not possible.

The ability to walk in time, whether to correct a past mistake or to gain insight into the future, has long been used in scientific myths and debates by physicists. While the debate continues over whether it is possible to move to the past, physicists have decided that going to the future is certainly possible.

There is often a belief that going forward or backward in time would require a machine, a time machine, to get there. To answer that question, we need to clarify what we mean by time.

Perhaps this is best explained in Hawking's "hypothesis of chronology", which means that nature does not allow its history to change, saving us from the possible problems of the time. Perhaps the most famous of these time-series puzzles is the so-called "puzzles of the grandfather" when the traveler returns and kills his grandfather. An old example is the paradox of grandfather when a traveler goes back and kills his parents or grandfather - the main episode of the movie Terminator - or otherwise disrupts their relationship - thinking "back in the future" - he was not born, or life changed forever.

The only exception to this confusion arose when Marty McFly almost prevented his parents from meeting in the past, which could lead to his disappearance. In the book Back to the Future, for example, Marty McFly goes on a rampage and hinders her parents from knowing they met, probably to prevent her presence.

A recent study by the University of Queensland could provide an answer to this perplexing mystery. In this study, researchers demonstrated statistically that it is possible to move in time without conflicts, indicating that the universe will automatically adjust itself to avoid inconsistencies.

If so, even if time goes by, we will never change events to create a different future. While these discoveries have been a source of enlightenment, there seems to be some evidence that although an extension of time may allow us to see the future, we can never visit the past. But it also means good news, because while these findings dampen our hopes of changing history, they may also remove the barrier to passing on the past. Over time it will make it possible to change the past, which does not make sense as it has.

Though possible, Hawking and others say you will never go back before building your time machine. If the passage of time is possible, then in theory it is only possible to return to where the original machine was made, and thus could mean that future travelers can visit us. Apart from Futurama, the idea of ​​going back in time will probably continue to fascinate humanity, but that part of the travel time - the "receding" part - will probably remain a delusion forever in the future.

Over the past decade, contemplated physicists have done a great deal of work trying to determine whether, in the universe, at first it did not have time to travel, it is possible to build a time machine, in other words, whether objects and geometric objects can be altered. . -a time in such a way that you create new ways to go back in time. Another possibility, while not necessarily leading to the passage of time, is to reveal the mystery of how other particles can interact more rapidly with light. Even the slightest chance of passing time is so fascinating that many physicists continue to study not only how it is possible, but also how it can be done.

Blake Crouch, a well-known science fiction writer who has written extensively over time, said this new study seems to confirm the meaning of certain travel times that are always uplifting. There have been many episodes of movies and novels based on time-bound paradoxes, perhaps the most famous of which is Return to the Future and Bees' Day. There are straightforward solutions to these calculations that include time-bound closed curves representing cross-country lines; A certain point of the future that is the cause of the earth's line exists in the causal past, and this condition can be described as a journey over time.

The logical paradox has given researchers a partial headache because, according to Einstein's common view of relationships, “closed time curves” are possible, theoretically allowing the observer to travel in time, and interact with his or her predecessors, which may jeopardize their lives. Some philosophers have responded to the controversy by arguing that it is possible to go back in time, but that it is not possible to change the past in any way, a concept similar to Novikov's proposed adaptation to physics. Another possibility is that the paradox simply indicates that such a move is impossible; The laws of physics must somehow prevent the passage of time.

Other theories, especially the relation of special and general, suggest that sufficient geometry or certain forms of space movement could allow for the passage of time and the future if such geometry or movement were possible. Attempts to confirm this were unsuccessful in both cases, ultimately due to inconsistencies between standard relation and quantum mechanics. However, in all studies, only a small amount of physics was found to prevent wormhole use over time.

Thorne suggested that by controlling the black holes, one could create a “hole” in space that would allow one to move instantly from one part of the universe to another. He later realized that theoretically this could be reused in the past. The woman's father wanted to know if she could text him in the past, on the day of the car accident that killed her daughters a while ago.

It is an interesting idea to get into the future that some people will go gradually. For example, Stephen Hawking pointed out in his 1994 book, Black Holes and Baby Universes, that if time were to pass in the future, people would do the same in our day.
