If human beings can really build a time machine, can they change history after going back to the pas

Time is not uniform at different locations throughout the universe, time is relative; In his famous special theory of relativity, Albert Einstein deduced that time will speed up or slow down according to the change in speed; A person who moves quickly passes more slowly than a person who is stationary; The faster the speed, the slower the time;

This question is obviously impossible, if you can change history, then everything will change in your time, and whether you can travel through time will become an unknown, so this is a paradox.

No, because time is irreversible. So it is impossible to go back to the past, let alone change history.

In order to understand the principle of time machine making, we must first know some laws of time and space. For example, the general and special theories of relativity that have been discovered now, as well as quantum laws. Of course, what I just said doesn't really matter.

The important thing is the theory of the existence of space-time published in 2047, which elaborates in this ** that time and space do not exist, and it can also be said that the past and the future are the same, and there are only matter and fields. Just as time flows slower in the atmosphere and faster on the surface, the closer you get to the "field", the faster the central field time is, but what does this mean? Different times in different regions?

Before we explain these questions, let's talk about what time is, which is just a measurement invented by man to understand matter. It's like two identical cups, one was poured into the water yesterday and the other was poured in today, and you will believe it when you tell you that they were both poured today. This is because you did not actually see the moment when the water was poured yesterday, so it is said that people's perception of time is a subjective perception of the material environment.

In fact, time does not exist. If time is really an observable property, then what was before the universe was big**?

Space also does not exist, and in Newton's vision of man is to live in a box-like world, with many lattices in the box, and man lives in this lattice. Later, Einstein overturned this theory that lasted for hundreds of years, and he believed that space is irregular, and time is also affected by space, so there will be a speed of time flow in different regions. The universe and humanity are both magical things, and the future, although for me it is the past, will emerge a new theory, a space-time in which the past and the present and the future coexist.

So what exactly is such a space-time? The so-called space-time is only composed of the resonant fields between matter and matter, and the strength of these fields causes the movement of matter, and the movement of matter creates the operation of the universe, and the emergence of planets, thunder, fire, water, and air have long been formed. Life begins to take shape.

The so-called beginning of the universe is a chain reaction caused by the wrong movement of matter, just like in the beginning, a substance that was supposed to move upwards went downward, causing other matter to change, and after a long butterfly effect, the universe was born.

To put it another way, since we know that time is only a product of human subjective consciousness, do we think that time does not actually exist? How would we survive if time didn't exist? The answer is the movement of matter.

When one day all matter stops moving, does it mean that time has stopped? Our cars, computers, mobile phones, cells in the body, tiny atoms and molecules, etc., have stopped, and time has gone again? If it takes a year for the material to start exercising, does that mean we have one less year?

But because matter stops moving, we don't know that time has stopped, so this year is like disappearing, existed but not known, so it is concluded that time does not exist.

Space is also a law set by human beings in order to understand the universe, but in fact, space does not exist, only fields and matter exist.

It hasn't been done yet, and it can't be done, because if there is one, one can live forever.

People say that time passes and there is no looking back. Many people grow up and feel good when they were young and want to go back to the past, and some people are old and especially miss the time when they were younger. There are also people who want to see how people lived in ancient times, and some people want to know what the future world will be like.

So there is a time-traveling drama. There are also people who hope to invent a time machine, which can travel to the past and the future, so should human beings invent this kind of time machine?

1. If you go back to the past and can change history, then you still don't have this kind of time machine.

When you go back in time, it's okay to just take a look, learn about the past, or relive the past. It doesn't make a difference, but if you can change history, then the impact is too great, and people know the butterfly effect, and if you change history a little bit, history can change decades or hundreds of years from now. This will be a terrible thing, and if it is used by some people with bad intentions, the consequences will be even more disastrous.

So, if you can change history, it's better not to invent such a time machine.

Second, if you can see the future, then there is no mystery in life.

If this kind of time machine can transport people to the future, then people can know what the future will look like. It is said that life is like a play, if a scene knows the future plot in advance, then I believe that this drama will not have much attraction. Therefore, it is better not to invent such a time machine.

3. If there really is such a time machine, then is this society already doomed?

If people can go to the future and see the things of the future, then it can only be said that this society is like a play that has been written. This also seems to be counterintuitive.

If a time machine can be invented, human beings need to invent it, because if they can go back to the past, they can rewrite history, recover many historical regrets, and make life better now, but at present, human beings do not have the ability to study the time machine.

Human beings can invent this time machine, and if they can really invent it, then we all want to go back to the past and hope that this technology will become more and more developed.

I hope that if I could, I would invent a time machine, so that I could go back in time to make up for my regrets, meet people I would never see again, and see how I grew up.

Actually, I don't want to, I think if the time machine is invented, the world order will be chaotic.

Time is not uniform at different locations throughout the universe, time is relative; In his famous special theory of relativity, Albert Einstein deduced that time will speed up or slow down according to the change in speed; A person who moves quickly passes more slowly than a person who is stationary; The faster the speed, the slower the time;

The time machine could have been invented in 2344!

The time machine is actually a uof, they are not aliens but people in the future, because of the laws of physics and nature, we can't see him, we can only see the light.

Tesla had already invented the time machine.

At present, it is theoretically impossible to build a time machine, and many of the current theories about time machines contain unverifiable conjecture theories.

Our best understanding of time comes from Einstein's theory of relativity. Before the advent of the theory of relativity, time was generally considered to be both absolute and universal, and that it was the same for everyone, regardless of the physical environment. In his special theory of relativity, Albert Einstein proposed that the time interval between two events we measure depends on how the observer moves.

It is important to note that two observers doing different movements perceive the same two events, and the time that passes between them is not the same.

Brian Green, a physicist and best-selling author at Columbia University, said that many people have had the idea of time traveling, either to reunite with a deceased loved one or to stop the horrific killings. Time travel is a beautiful wish, and it provides wonderful material for all kinds of science fiction**. There have been countless ideas about how to go back in time.

These assumptions, if carefully scrutinized, are playing a side game with physics. In our view, almost none of these assumptions are true. ”
