What are the benefits of inventing a time machine for humans

Before we get into that, we should first talk about the time machine itself. Theoretically, a time machine can be made, but the special theory of relativity says that our time travel can only go to the future, and not to the past, so even if someone can get high technology in n years, it will not be able to go back to the present to harm us. Later, Einstein introduced the general theory of relativity through refinement, saying that it is possible for us to choose to go back to the past in time travel, but we only intervene in history as an observer, and cannot intervene in history as a participant, and if we really want to intervene in history, we can't change anything, because time and space will begin to separate at the time when you participate in history, and you will enter another historical space-time with you in a parallel universe, and what you will change is only the world of another universe, and it will not have any impact on our real world.

Therefore, even if the time machine can be used successfully, it will not have much practical significance for our human real life.

The words are divided into two ends, if we can shuttle back and forth in this dimensional cosmic time we are in, and can change the course of history at will, and this high-tech is mastered by a madman like "Stupid La Lantern", haha, it's nothing to us, it's a big deal to wear a turban on our heads, and worship the dome building three times a day, then the Yankees will be miserable, and anyone who is not used to the "La Lantern" brother will be humanely destroyed.

Do you mean going back to the past and the future? I don't think that's possible.

To make human beings truly and completely free from the instinctive behavior of animals.

At present, it is impossible to construct a space-time machine in the confirmation theory, and many theories about the space-time machine now 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. ”

This is still inconclusive, but just imagine, if you can make it, you can't go back to the time and space before the time machine was created, because the time machine has not happened yet, so if it is created, at most it can only go back to the time and space after the time machine was created.

With the development of science today, the field of research has advanced to the two extremes of maximum and minimum. However, whether it is in the deep space of the universe or inside the nucleus, we cannot verify it ourselves. The answers given by these theories may be even more absurd than a blind man touching an elephant.

It's like quantum theory, when I look at you, you collapse into what I see, and if I don't look at you, you disperse behind me. Is this the truth of the theory or the absurdity of our thinking?

In terms of the current physical knowledge of human beings, it is unrealistic to travel through time and space, but Einstein proposed that time can stop when an object reaches the speed of light, and some scientists have proposed that even if it exceeds the speed of light, it can only reach the future at a high level, and cannot go back to the past. In short, we can only dream now, maybe one day it can really be realized, but we are afraid that we will not be able to catch up.

See how you ask for a time machine.

If you want to go back to your past and go faster than the speed of light, it's that you will see your past self like you are watching a movie.

If you want to touch it, the theory can't be realized yet.

If you want to see the ancient galaxy, Hubble has made it happen.

This, Doraemon, have seen too much???
