If human beings can travel in the future, why haven t we seen it back so far?

With the rapid development of technology, humans may actually be able to travel in the future, but natural travel is limited due to the fact that it will rewrite history. Crossing is the subject of many science fiction films and TV series, so will human beings really realize crossing? According to the calculations of scientists, if human beings really study the speed of light, travel is also possible, the reason why we have not seen people who travel back to the past is that they are not allowed to travel casually, after all, any crossing will change the development of the entire history.

1. With the development of science and technology, there may be time shuttle machines in the future, and people can go back to the past in the future

The dream of time and space travel has always been there, so can future humans really travel back to the past through time and space? I think it's possible. According to the research of scientists, as long as the speed of human beings reaches more than the speed of light, a special space-time excuse can be generated, and then it is possible to go back to the past through machine calculations; If future people can really go back to the past, why are there no future people around us?

The existence of time and space travel does not mean that human beings can use it casually, therefore, we cannot see any people who travel through time and space to return to the past.

2. Anyone who travels back in time will change history, and considering the magnitude of the impact, people in the future should be forbidden to travel casually

If human beings really invented time travel, it is normal to think that no future people will return to the earth, after all, time travel itself is produced for experiments, not for self-satisfaction; In the future, time travel should be turned off and managed by specialized people, and it is not a machine that ordinary people can use. If people in the past knew what was going to happen in the future, they would change from striving to develop to being lazy and waiting, and in the end, they would have seriously changed history.

NopeThe person who came may have mastered the ability to travel through time, but it is forbidden for ordinary people to use it in consideration of changing history.

If it can be traversed, then there are two explanations for this phenomenon.

The existence of parallel universes. Imagine what would happen if you traveled back in time and chose a completely different choice at the moment you made a choice than what you are now a reality? Is it very likely that something else will happen that is completely different, and that this completely different development will be contrary to what you are doing now.

How do you explain this happening? That's the parallel universe. In other words, when you make another choice, the other development becomes another universe and does not interfere with your previous universe.

Wormhole theory. A wormhole is an important entrance and exit through time and space, and a wormhole is a force field close to a black hole. With our current technology, it is clear that we cannot build a wormhole entrance or a wormhole exit.

Since there is no exit, then, in the distant future, even if there is an entrance to the wormhole, it will not travel to our time.

The original principle of traveling through time and space was discovered through the twinkle of stars, and it was scientists who discovered that every dimmed star was hundreds of millions of years ago, and the reason why it is only seen now is due to the speed of light.

So there is a hypothesis, as long as the speed of a person reaches a certain value, it can travel through time and space, and this time and space can be the future or the past.

As for why you can't travel back in time, this is going to talk about another theory, grandmother refutes it, that is, if you go back in time and kill your grandmother, will it still exist, then it won't exist, how can your grandmother die.

Because according to the theory of relativity, it is almost impossible to go back in time beyond the speed of light, so there is no one who travels from the future to the present.

Because there is no such thing as crossing, it is impossible for people to travel from the future to the present, which is a very superstitious statement, and everyone should look at it rationally.

Such a crossing is likely to have an impact on future development, so naturally there will be no particularly big moves.

Yes, but there is no way to achieve it with current technology, I believe in Einstein's theory of relativity: "When an object moves at or near the speed of light, the mass increases, the distance becomes shorter, and the time slows down; If the object moves beyond the speed of light, time will flow backwards". The spacecraft moved in a straight line at a constant speed in the same direction, at a speed of 1 million times that of the "train", from the same position and direction of the locomotive of the "train" in 2230.

Then, the time it takes for the spacecraft to reach the end position = 2230 * 365 * 40,000 kilometers 10,000 kilometers seconds * 1 million = 2230 * 365 4630 seconds = seconds, which is recorded as 18 seconds. It takes 2230 years from the Qin Dynasty to today on Earth, but it takes less than 18 seconds to get from the Qin Dynasty to today on a faster-than-light spacecraft, which is the relativity theory of the same event in two different space-time coordinate systems. The ratio is one second per year, which means that one second on a faster-than-light spacecraft is equivalent to about 124 years on Earth.

After 124 years on Earth, and only 1 second on a spaceship, isn't this time slowing down? How slow is it? People on Earth have experienced a lifetime of ups and downs from birth to death, and no one on a spaceship has had time to blink an eye.

Now, if we roll the "train" back to Earth, then, the Earth will rotate for 2230 years, and the spaceship will only need to fly for 18 seconds; In the same way, the spacecraft has been flying for 1 second, and the Earth has been spinning for almost 124 years. It doesn't matter what direction the spacecraft is flying and whether the Earth's rotation and revolution are forward or reversed.

At this point, in fact, a problem has been proven:

It is impossible to travel back in time and space, but it is both theoretical and practical to travel back to the future. Needless to say, spaceships exceed the speed of light, as long as it is close to the speed of light, or fast enough, astronauts can enter the future ahead of time. But be sure to note that the future that the spaceship enters on the Earth is not actually the future, but the Earth has really experienced so many years.

Therefore, it is impossible for astronauts to go back to the era when they set off.

Yes, but I think it's different time and space, you can only look at each other, not touch.

Through? Theoretically achievable.

There are 5 ways to travel to the future, all of which are possible, but the consequences are unbearable!

When will we be able to go to the future, and I don't know when technology will be able to reach it, and will it be possible in 50 years?

No, if you don't die of old age, will you die of old age?
