Hello, I would like to share another hypothesis about the possibility of time travel, which I wanted to write about for a long time. However, due to its complexity, I could not think of a suitable explanation to describe it. I am used to explaining everything with examples so that people even far from science could understand my hypotheses. This time it was harder to find examples. So for earlier I apologize, if anything is not clear.
In physics there is such a thing as "time axis". It is also called the “arrow of time”. The time axis is a straight line stretched from the past to the future. It denotes a familiar world where the flow of time goes in one direction.
How do we determine that time is flowing? We determine this by the changes around us. And not only. If we closed our eyes and did not see anything around, and at the same time did not hear either, then we would still feel that time passes. Eventually, different thoughts appear in our head. That is, what we think about also changes. The synapses of neurons during the thought process are constantly moving due to the arrival of various signals to them from the outside world.
Changes in the location of physical bodies occurs due to the fact that they are constantly moving. In other words, movement is the indicator of time. However, oddly enough, the movement can occur not only in one direction.
If we saw a world where time goes backwards, we would see that movement also occurs. It's just that everything moves the other way around. You can call it "RETURN WORLD". The reverse world is a world where time flows in reverse.
Let's remember the change in time relative to the perception of objects when their speed reaches close to the speed of light. Scientists have experimentally proven that there is a time dilation effect.
Imagine there is a spaceship that can accelerate to that speed.
Now imagine that you are on Earth watching this spaceship and its passengers. When the ship begins to reach a speed close to the speed of light, you will see that the passengers in it move as if in slow motion. Moreover, the closer to the speed of light, the slower their time goes. However, this will only seem to you. On the contrary, it will seem to them that everything around is moving faster. For example, if they were flying to the nearest star at such a speed, they would think that they reached it in a few weeks or even days. It would seem to you that they got there in a few years. (All this would be only if the ship could accelerate to such a speed in seconds, in real life, for a human body to withstand this, it takes a year to accelerate or even more.)

The object can no longer accelerate completely to the speed of light, since the closer to this speed, the greater the mass of the object. At the speed of light, it would already have an infinite mass, and to move such a mass, you need infinite energy. Therefore, it is impossible to accelerate to the speed of light, according to current scientists.
However, let's mentally remove this mass limitation and leave only the time variation.
Imagine, instead of a spaceship, a wheel that rotates at a constant speed. This wheel has a perception of time as a living person.
So this wheel has reached a speed close to the speed of light. The wheel will seem to be spinning at the same speed, and to outsiders it will seem that this wheel has slowed down.
Now let's imagine that the wheel has reached the speed of light. Since the closer to the speed of light, the stronger the deceleration, it can be assumed that at the speed of light the wheel will stop. It will not rotate. Now imagine that the wheel began to move faster than the speed of light. Here we will see that the time regarding the observers of the wheel has gone backwards. The wheel just began to rotate in the other direction. That is, "move" in the other direction. In other words, when the speed of light increases, the movement is reversed. However, the wheel itself will feel that it is rotating in the other direction. That is, it turns out that the wheel rotates to the right and to the left at the same time. A kind of superposition that we observe in the quantum world when we consider the spin of an electron or other elementary particle, only this time in the macrocosm.
Considering the change in the direction of the arrow of time, we have four options for the rotation of the wheel on the plane.
1. When the wheel rotates to the right, its time flows as usual. (The wheel also rotates to the right with respect to an outside observer)
2. When the wheel rotates to the left, its time flows as usual (With respect to an outside observer, the wheel also rotates to the left)
3. When the wheel rotates to the right, its time flows in the opposite direction (relative to an outside observer, the wheel rotates in the opposite left side)
4. When the wheel rotates to the left, its time moves in the opposite direction (relative to an outside observer, the wheel rotates in the opposite right direction)
However, as we know, it is impossible to exceed the speed of light. As shown by many experiments, scientists have not received convincing evidence of exceeding the speed of light. It means that we are not given to observe such a change in the arrow of time.
Let's do another thought experiment.
When the wheel allegedly began to rotate in the other direction due to the change in its arrow of time, in the opposite direction, everything inside it began to move. The molecules in it began to vibrate in the opposite direction (although we would not have noticed this). That is, all movements began to occur in the opposite direction.
Imagine, instead of a wheel, a man. A person's perception of time is created by various movements within him. If a person exceeds the speed of light, then it turns out that everything inside him will move the other way around. This means that the perception of a person will also be the opposite.
In other words, a person will live in a reverse world, where time flows backwards.
If this is a passenger of a spacecraft, then all space bodies relative to him will move in the opposite direction. In other words, he will end up in the reverse world. With respect to an outside observer, who is in time, where the arrow of time goes in the direction we are accustomed to, the passenger of the spacecraft will move in the opposite direction. He will walk the other way around, talk the other way around - he will think the other way around. It will seem to him that on the contrary, all people live.
If we wait for 2018, it will wait for 2016. (Of course, the passenger himself will know why this is happening). In other words, he will live from the future to the past. He will live in a reverse world.
Many probably did not understand how he would get into the past. Let's go back to the wheel. His example is much easier to explain.
The wheel is in the opposite world, which means it moves the other way around. It not only rotates in the opposite direction, but also flies in the opposite direction, relative to an outside observer.
Now let us remember that the wheel, before entering the reverse world, reached the speed of light. He flew in one direction. If he exceeded the speed of light, he would be flying in the opposite direction. How would it look from the outside?
So again the wheel reaches the speed of light. At the same moment, another wheel flies towards him, spinning in the opposite direction.
This raises the question: where did this second wheel come from in space? The fact is that the wheel that appeared from nowhere is the same wheel. It has already exceeded the speed of light.
In physics, the fact is known that if it were possible to exceed the speed of light, then it would be possible to travel into the past. In other words, we observe a wheel from the present and the same wheel that moves into the past. That is, our wheel is in space in two places at the same time.
In other words, if we saw that something exceeds the speed of light, then it looked as if we see two objects approaching at a speed close to the speed of light to meet each other.
From the physics course we study at school, we know that an electron moves around a nucleus at a speed close to the speed of light. However, in quantum physics, the electron does not move, but rather bounces from orbit to orbit. Moreover, in an instant, an electron is in two places at the same time. At the same time, for each jump, the electron has a different spin. (Spin is the moment of rotation of an elementary particle).
Why the electron does this, scientists still cannot explain.
However, if we assume that the electron moves in time, then it becomes clear why the electron is in two places at the same time. We can also compare an electron with our wheel and then we will understand why it has a different spin.
You ask, where did the mass go, which should, according to the idea, grow? The point is that the mass is created by the gravitational field. However, besides the gravitational field, there are other fields in the atom. Electromagnetic fields. There are nuclear forces in the core. Perhaps all fields somehow compensate for the effects of the gravitational field. As a result, the mass supposedly disappears for a while. This is where the effect is observed, which changes the arrow of time of the electron.
We can say that many of the questions that now arise in quantum physics can be solved using a change in the arrow of time.
At the same time, if you study quantum physics well, you can understand how time movements can occur using the arrow of time.
Now many scientists are thinking that time travel could be possible if it was possible to get into a black hole. However, this is a rather dubious idea. And when do we even get to the black hole to check it out?
Perhaps we'd better first try to reach a speed close to the speed of light in the macro world. So, we will know exactly what is happening at near-light speeds. If our above hypothesis of the existence of a reverse world is justified, then time travel can be done within the solar system using this reverse world. We will not need to look somewhere far in space for a black hole.
