When the speed is fast to a certain extent, will it travel through time?

Einstein's theory of relativity said that parallel space-time is opened in a way that when an object is about to reach a certain level, it will pass through the time limit, perhaps through it.

The special theory of relativity holds that time is relative, not absolute, and that traversal is temporal and spatial, which I don't think can be done.

Theoretically, the faster the speed, the slower time becomes, and when approaching the speed of light, time almost stops, then you reach the speed of light time may be equivalent to forbidden.

I expect that the crossing is achievable, but I am worried that if I can travel through it, will time be disrupted and everything will become complicated?

If it can really be crossed, why is there no future person who has traveled to our modern age, is it that we are now at the end of time? So it's almost impossible to cross.

I've seen a lot of books and movies, and I'm fantasizing about the future, and I think it's possible, just like the successful take-off of an airplane, just like the discovery beyond Earth.

As it is now said, at or beyond the speed of light, time stands still or flows backwards, but your body does not travel through it.

Not really. Even if your speed reaches the speed of light, it can only be said that time stands still relative to you, and that time stops flowing in a particular area where you are located.

In fact, this universe does not allow objects with mass to accelerate to the speed of light, so how hard is it to reach the speed of light? Not to mention that you're going to speed faster than light.

Humans may not be able to do it now, but everything has a weakness or a breakthrough point, and maybe one day it will really happen.

Time you say stop, stop. Is there still a crossing?

When the speed exceeds the speed of light, it is possible to travel through time and space, but this is contrary to today's scientific theories. The theme of crossing has always been a favorite theme of the people of my country, and it is also a common theme in various TV dramas and movies. Rewind the time to seven or eight years, you turn on the TV, almost all the channels, are broadcasting "time travel dramas".

Crossing seems unattainable for human beings, and it is precisely because of this that human beings are full of yearning for it. But what would you think if someone told you that crossing is not a fantasy, but "achievable"?

Through Einstein's special theory of relativity, we know that time and space are not "absolute" and stagnant; Rather, it is always in constant flux, and it is "relative". As long as we move closer to the speed of light, the slower time will be for us; When the speed of light is reached, space-time stops at that moment.

What is the speed of light? 300,000 kilometers per second. If we continue to develop and surpass the speed of light, will we be able to accomplish the feat of "time and space travel"?

It's possible. Among the existing dimensions, Wayne, a professor in the Department of Astronomy at Columbia University in the United States, once proposed such an idea.

When the speed exceeds the speed of light, the object will be swallowed by the "wormhole", realizing the quantum transition. This kind of migration may take human beings to unknown corners, or it may allow us to transcend dimensions and go to the "four-dimensional space". In the four-dimensional space, time and space are presented in a linear manner, and we only need to "generalize from points" to the past or the future.

However, this does not conform to existing physical theories. Why? In general relativity, the speed of light can only be approached, not reached, and is the upper speed in the universe.

It's very simple, some starlight was sent to the earth tens of billions of years ago, and the earth was formed only a few billion years ago, exceeding the speed of light, but halving or reducing this time by more than that, you can't go back to the past, you can't go to the future, you only go beyond the speed of light, not beyond time.

Not necessarily, theoretically it is possible to go to the future after the speed exceeds the speed of light, but no one knows whether it will travel through time and space, it is just a guess by scientists.

Yes. When you go faster than the speed of light, you can travel through time, but not yet.

No. According to Einstein's theory of relativity, if you travel through time and space, you need to distort time and space.

It doesn't change the time, for example: today there is an extra star in the sky, 1 light year away from us, in fact, this planet was formed 1 year ago, but it takes a year for its light to reach the earth and be discovered by today's people. If someone on a star reaches Earth faster than the speed of light, maybe yesterday or last week, can you say that their home star has not yet formed when they arrive on Earth?

Then the question arises again, for it it has already reached the earth, for the earth your planet has just been formed, and you can even see that the original you have just taken off from the planet, so will there be another you coming? Hahahaha.

The scientific community is still unsettled on this issue. 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 really travel through time and space, and that time rewind is just an illusion, and that faster-than-light events will cause a series of quantum mechanical reactions in time and space, which will eventually make it impossible to travel through time and space.

Of course, there are also scientists who disagree, and there is not only one way to travel faster than the speed of light.

As for the trajectory of history, it is also discussed in detail in "A Brief History of Time", and there are also several different theories, but in general, history is dominated by randomness, that is, uncertainty, and not everything is fixed and infallible.

The first speed is not as fast as the speed of light, the speed of light is fast enough, you can see it immediately when you take the flashlight out, so do you see the flashlight traveling through time and space? No, the speed of light is the fastest, the distance between human beings and the moon is hundreds of light years with the speed of light, and the time and space travel is because of the change of the magnetic field.

According to the special theory of relativity, the faster the speed, the slower time passes, and when traveling close to the speed of light, time is almost static! For example, thousands of years have passed since you flew in a spaceship for 10 days in the universe at close to the speed of light and returned to Earth! And you've only had 10 days to go!

And the time of other earthlings is thousands of years! The speed of light is not reached. Of course, if it is reached, the time you go backwards = (your distance - the distance that the light travels at the same time as you) the speed of light.

This is a false proposition. When it comes to the greatest physicist in human history, although there have always been endless debates and many propositions, it is believed that Einstein, the famous physicist of the last century, is definitely worthy of this title. Not only did he leave a mark on the world of physics;

It has also made outstanding contributions to the development of human civilization. In particular, his "theory of relativity" reveals that under the influence of the speed of light, space-time changes each other, almost opening the door to a new world for us.

The speed of light is arguably the most magical speed in the universe. It is rumored that as long as the speed breaks through the speed of light, then time and space will expand indefinitely, allowing us to "travel through". When the time comes, the bridges in the movie will no longer be impossible; Humanity can plunge into the long river of history, change the past, and participate in the future.

Is this correct? Just kidding, of course it can't be. Things from the past have happened, how can we change them?

In the philosophical world, there is a famous "grandmother paradox" that illustrates this situation. Reaching the speed of light will indeed cause the "Lorentz Change", which will change the flow rate of space-time;

However, this is unlikely to bring about the effect of "crossing". Albert Einstein once gave an example of what the speed of light does on time: if a person is running at the speed of light, the speed of the second hand in his hand will be infinitely close to stagnating.

In other words, in a single space, the speed of light can slow down the flow of time infinitely, but it is impossible to cross the timeline, which is beyond the theoretical scope of "general relativity". Generally speaking, only sci-fi ** will have such a scene.

Moreover, the so-called "reaching the speed of light, time pauses" is also relative to the outside world. Time is still moving at a normal pace for you. Many people think that the speed of light can bring "eternal life"; This is nonsense.

All in all, the magical operation of "crossing" and "immortality" should not be pinned on the speed of light.

According to Einstein's theory of relativity, the mass of an object will increase with its velocity when it is moving at high speed (macroscopic high speed, i.e. close to the speed of light). When the velocity is infinitely approaching the speed of light, the mass of the object will tend to infinity.

I don't think it's just a matter of being fast enough if you want to cross.

It's really possible, but at the current rate, it's not fast enough.

No, the crossing is just a plot in **, not true.

This kind of thing must be fake, and it is impossible for people to really cross over.

This is possible, but it is difficult to reach speeds faster than the speed of light.

This one is said to be able to travel as long as you reach the speed of light.

Because according to the relevant theory in Einstein's theory of relativity, objects are moving at high speeds.

Bad extra money can only put you in a state of fantasy.

Crossing is speed, not speed.

This claim is false because there is no scientific basis for this.

No, the current test with the speed of light will travel through time and space, which is very difficult to achieve.

No, it has not yet been discovered that time and space travel can be realized, and time and space travel is just a conjecture in people's psychology.

It is possible to travel through time and space when the speed is fast enough to make time negative, and it is almost impossible to reach a negative number of time. The faster the speed, the slower the time, the theory is right, it is just a contest of speed and time, and it does not make time change. It's not that you can travel faster than the speed of light, that's not right.

For example, when you stand in front of a table and the speed of the negative time reaches the back of the table, you will see the front you, that is, there are two you, and when the negative time returns to the original table, you will disappear, just like a dream, the greater the negative time, the longer you stay in the past, this is the crossing.

Idealization works, but it doesn't, because there's so much pressure that can squeeze people out, and there's also rapid friction. I drove a distance and found that time was slowed down, albeit by a few microseconds, which could be illustrated by the fact that time could be slowed down.

It's impossible, no one has really tried anything like that so far, and there is definitely no way to achieve time travel.

No, the current technology has not yet reached that level, we can shuttle at will, and the faster the speed, the slower the time is for you.

The premise of time travel is to reach the speed of light, but there is no technology to achieve it now.

It is possible to travel through time and space, and according to the special theory of relativity, the faster the speed, the greater the mass of the object, the greater the gravitational field excited by the object, and the more space-time bends around the object. If the speed exceeds the speed of light, it may disappear in this space-time and appear in another space-time, but these are our guesses, and the physical laws around and itself when the speed of a real object reaches or exceeds the speed of light have not yet been discovered, and it is too arbitrary to draw conclusions too early.

The phenomenon of slow clock, ruler shrinkage, and superluminal time reversal can all be achieved by sound experiments, and there is no problem that cannot be explained by classical theory, which can only prove that Einstein's conclusion is problematic, and he ignored the problem of measuring speed, and regarded "phenomenon" as "physical essence".

No, there's no denying that having a time machine is a great thing. Who wouldn't want to go back in time, change history, and make themselves superstars. Scientists have also given us some ways to achieve time travel.

But wait, they seem to have forgotten to send you a copy of the Crossing Codes

Time does not rewind when the speed is close to the speed of light.

It will only be close to stationary, and as the object accelerates, the mass increases, the length is compressed, and the atoms slow down, equal to the speed of light, c, and all changes cease when it is equal to the speed of light.

The speed of gravitational waves should be faster than the speed of light". Experiments have shown that there are substances that move faster than the speed of light, such as light pulses that are measured to be 300 times the speed of light!

When the speed exceeds the speed of light, then from the perspective of time, what is seen is the past, but it is only a scene of the past, not a return to the real world of the past.

In this three-dimensional world, light is one-dimensional and always forward. In the four-dimensional space that we can't imagine, in addition to going up, down, left, right, front and back, a timeline is also added. And when the speed reaches the speed of light, it can be said that the object is stationary, just like the three-dimensional we see that the two-dimensional ** is stationary, and we can see ** all the same; Suppose there is a creature that is four-dimensional, then it looks at us as we see **, it can transcend the concept of time, that is, it can see at a glance that our life is from the beginning to the end.

So according to the four-dimensional concept of time, we can think that time is not a vector, then the solution is that when the speed exceeds the speed of light, time can be reversed.
