Use scientific knowledge to explain the conditions for traveling through time and space

Preface: There will be black holes in the universe, and human beings also know that black holes are very scary, because black holes can swallow any matter around them, and once they come into contact with black holes, they will be torn to pieces by strong gravity. If you want to use wormholes to realize time and space travel, it is theoretically possible, but it is difficult to do it if you want to really realize it, because human beings do not know a lot about the universe and wormholes, so if you are sucked into a black hole, there is no way to predict what will happen next.

Although there are a lot of scenes in the movie, the wormhole is seen as a folded space-time, and after being sucked into the wormhole, it will appear on the other side. But in fact, what humans know is that the matter swallowed by the wormhole does not appear in the universe again, because the gravitational force in the wormhole is very strong, and the density is also very high, so once it is swallowed by the wormhole, it will be crushed. Because the space of the wormhole is very distorted, such a distorted space requires a huge amount of energy.

Wormholes are also real in the universe, but if humans are sucked into them by gravity, they may come out from the opposite direction, but they may also be one with wormholes, in the dark, unable to move forward, and unable to see anything around them. At present, human beings know very little knowledge, because the universe is relatively mysterious, and there is no way to understand it thoroughly in a short period of time, so everything is unknown. There may also be a celestial body in the universe called a white hole, where a black hole has no return, and a white hole may be the opposite.

But there is no way for humans to enter the inside of the white hole, and the objects inside the white hole may also escape outward, if the black hole and the white hole are connected, a different space may be constructed, this channel is the wormhole, so it is possible to cross through the wormhole, but the current human technology is not able to achieve, as for whether it can be realized in the future, it remains to be considered.

No. Because the current technology is not enough to support the crossing, it is also a fantasy, and it is impossible to use wormholes to achieve crossing.

OK. This is because the current technology has not reached such a level and cannot use wormholes to achieve traversal.

Today's science and technology still have certain limitations, and time travel is still a virtual thing. At present, human beings have not mastered the laws of space, and cannot carry out crossing.

In my own opinion, from a scientific point of view, I don't think it is possible to travel back to the past through time and space through a time tunnel, this is just a beautiful illusion of people, and there are unfinished things in the past that need to be completed in the past, for example, many TV series and movies are told and interpreted through time and space.

The Spanish movie is called, Time Authority, and she is through the heroes and heroines in it, through the tunnel through time and space, to a certain fixed time in the past, to do something historical, such as a famous person received a danger or threat, if he is about to finish something, they will help him to rescue him, to help him complete it.

I think it's possible, just say that your speed is faster than the speed of light, then you can exceed the speed of time passing, and then you can travel back.

I thought about it, and it seems that this is really the case, if you are fast enough, faster than the speed of light. Then you can go back to the previous time. Because your speed is already faster than the speed at which it passes.

But the hard thing to do is the speed, because the speed of light is very difficult to achieve in real life, or under existing conditions.

So it's not possible with today's technology. ‍

No, the most scientific theory now is that time can only represent the difference between the speed of physical change and chemical change, but cannot reverse physical change and chemical change, and time will not store a point in time space for you, so it is nonsense to travel back to the past and the future through time. To put it simply, the speed of cosmic time is determined by speed and gravitational field, for example, in spacecraft space with a speed of one-tenth of the speed of light, and at the edge of the black hole event horizon, time will be much slower than that of the earth, and the physical and chemical changes in the above two spaces and the earth are all positive changes, but after a period of comparison, it will be found that the same experiment done in the above two spaces, the earth has done ten or more experiments. From the perspective of civilization development, for example, the above-mentioned two spatial development civilizations have just changed from the industrial revolution to the information Internet era, and the earth may be a higher civilization stage than informatization, and the civilization progress is fast, and the fundamental reason is that physical and chemical changes are fast.

Change is irreversible, and of course, don't expect time to store space, and you can go to a certain point in time through time. And in that case, the weight and energy of the universe are infinite, because time is in the universe, and time stores space at infinite points in time!

You can't go back, even if you exceed the speed of light, you can only see the past, but you can't change it, just like watching a movie.

With the shadow of love.

Don't be naïve! If you could go back in time, would you be sure if we were in the past or in the future? Besides, some people say that an object moves faster than the speed of light and then goes back to square one!

And the original object at the origin has not disappeared, that is, the object moving at the speed of light has returned to the past! Suffice it to say that this is just self-deception. In fact, when an object moves faster than the speed of light, only the image of the object remains at the origin and is no longer an entity.

To put it simply, when an object moves faster than the speed of light and returns to the point of origin, the reflected light from the object at the point of origin has not yet reached the observer's eye. In fact, even if you move ten times faster than the speed of light, it will consume time. For example, you have traveled 300,000 kilometers at ten times the speed of light, and you have only taken a tenth of a second.

So, no matter how fast you are, time is still moving. It's just that it takes less time. Time is just a concept, a criterion.

and not entities.

Faster-than-light is a huge and strange problem, and you can't explain it even if you want to explode your mind, just like Albert Einstein thought about quantum mechanics in the last century, you can't understand it anyway, and you can only find a superluminal example to find the real answer.

These madmen, gods and demons who deceive people in the name of science, see people go back in time!

In the world above, it is possible.

Many general methods, such as: soul travel, is to let your soul go to the time and space you want to go, and then attach it to someone in that time and space, you can ask a master with high mana to help you

In addition, when sleeping, the astral body (mind) travels through the form of dreaming, which is the mind crossing

There is also a medium that leads you through a medium, such as gemstones, mirrors, crystal bracelets, which can be used by the whole person

There is also the ability to find time machines, or space-time portals to travel through them, (this is more difficult) and there are strong impacts to the brain, car accidents, etc., (don't try) according to scientific point of view:

When an object moves faster than the speed of light, time slows down, and when an object moves faster than the speed of light, it will flow so that we can travel through

The landlord has nothing to practice

You're on the road, a car comes by, you close your eyes and don't move, you're crossing, you're in another world. Just kidding.

This question is not very realistic, when the speed of a person exceeds the speed of light, you can travel through time and space, but you have to think, the speed of light is 300,000 meters per second, can it be reached?

The chaos of time and space has the possibility of 0.0000001 in 100 million.

Just look at the Cosmic Wanted and you'll know.

A few days ago, some American scientists declared that the "time machine" is purely just a great dream, and it is impossible for human beings to travel back to the "past" through time and space to meet their teenage selves or their parents who have just fallen in love.

Previously, many theoretical scientists have proposed feasible methods of "time travel", the most famous is the "wormhole" - this is a time tunnel that theoretically connects two space-time locations, which may be in completely different universes, or two places in the same universe, and matter can quickly reach the destination of another space-time through the entrance of one "wormhole".

Chio Kaku, a physicist at the City University of New York in the United States, said that creating a "wormhole" in the structure of space-time would require the energy of a star, which is obviously not something that humans can do. Even if humans could open the entrance to the "wormhole" and use it to travel from one place in the universe to another, from one time to another, humans would not be able to control the "time machine" to travel freely and accurately to a certain time and place in ancient times, as depicted in science fiction movies.

But scientists say it's much more likely that humans will "travel back in time" to the future. Green, a physicist at Columbia University, said, "If you want to know what the Earth will look like in 1 million years, I'm going to tell you what to do."

I can calculate that when you build a spaceship and fly at close to the speed of light for a long time——— when you return to Earth and walk out of the spaceship, you may only be a year old, but a million years have passed on Earth. ”

From the premiere of Charlie Chaplin's movie, someone used a mobile phone a hundred years ago?

This is discussed in Stephen Hawking's "A Brief History of Time", and it is recommended to take a closer look at this book and learn about relativity and quantum theory by the way, which is more conducive to understanding. Hawking believes that even if it really exceeds the speed of light, it is impossible to truly travel through time and space.

Through? Theoretically achievable.

Are you talking about time or space? At present, people are studying the rapid transfer between spaces, time is not easy to say, then we have to see where we are in time, if we are real time, it is impossible to travel to the future, because everything has not happened yet, if we are in a secondary position, for us, the main time is the future, for the main time we are the past, the people of the main time can travel to the present (for them the past), but cannot travel to the future.

It's almost impossible, because to travel through time is to change history.

Take a chestnut: a scientist in 3012 wants to go to 4035 to learn more advanced science and technology. But the scientists in 3012 have gone to 4035, and there will be no progress in science in 3012, so history will be changed. Those who go will disappear into space.

I believe that in the future human era, we will be able to travel through time and space and update the era of games.

Theoretically, yes, but it's hard to do. It can't reach that speed at all, like 4 times the speed of light.

Yes! Actually, I'm here in 2010.

In the movie Star Trek, a brand new acceleration technology is mentioned, which is the warp engine. In the movie, the spaceship flies at warp speed and can travel back and forth through cosmic galaxies, traveling to the area where it can defeat light-years or even tens of thousands of light-years in a split second. So what is a warp engine?

As early as Einstein's special theory of relativity, it was proposed that no matter can exceed the speed of light, so if human beings want to explore the deeper universe, they must find a new way to accelerate.

You must know that celestial bodies are measured in light years, and the closest star to the solar system also has light years, and the diameter of the Milky Way reaches 160,000 light years. So scientists have conceived a warp engine that can break the speed of light, and instead of a thruster as we know it, it can fly by bending space-time.

We know that the curvature of space-time has long been proven, and that space does bend due to massive objects. The warp engine uses space-time bending to compress the space in front of it, and expands the space behind it, so that the spaceship is wrapped in a curvature cannon and moves. To understand this concept, it is necessary to mention Einstein's model of four-dimensional space, that is, the three-dimensional space of the universe in which we live also bends to four dimensions.

This shows that the space-time structure is dynamic and can be extended, stretched and contracted, and the warp engine takes advantage of this to create an artificial driving field around the warp spacecraft with antimatter-driven drive engines, so as to distort space-time, causing the space in front of the spacecraft to shrink and the space behind the spacecraft to expand.

The place where the warp speed ship sails is called the warp speed cannon, so as to achieve a forward speed beyond the speed of light, in short, in fact, the space has been distorted, and the speed of the spaceship itself has not increased. It's like it takes five seconds for a piece of paper to move from point A to point B, but you can fold the sheet and the distance between the ends of the AB will be shorter, the speed will be the same, it will take less time, or even just a second to get from A to B.

The degree of space curvature is known as the new warp level in warp engine technology, and if the spacecraft reaches the first level of warp speed, it is equivalent to the speed of light, and the warp speed of nine can reach the speed of light, crossing the solar system in just 26 seconds, and crossing the galaxy in only 66 years. Although the warp engine is so rebellious, it is only at the theoretical stage, and if humans really master the driving engine, they may be able to uncover the secrets of the universe.
