Briefly describe how time stops when the speed reaches the speed of light

To put it simply, let's say a car is running at the speed of light, and you're not as fast as it, so you see him moving forward, and then you're moving at the speed of light, and you see him standing still, and you're moving faster than the speed of light, and you see him going backwards.

The hardest thing you understand is why it has to do with time.

First of all, you have to understand that the universe is at least four-dimensional (according to Stephen Hawking, the universe is at least 11 dimensions), so what is four-dimensional space?

One-dimensional space is a line made up of an infinite number of points, two-dimensional space is a plane made up of an infinite number of lines, three-dimensional space is a three-dimensional space, made up of an infinite number of planes, and a four-dimensional space is made up of an infinite number of three-dimensional spaces, and you may not be able to perceive a four-dimensional space.

I'll give you an example, for example, if a cuboid is left unmoving, it's three-dimensional, but I drag it at a constant speed, and it moves one centimeter in one second, two centimeters in two seconds, three centimeters in three seconds, and there are seconds in one second, and there are seconds in seconds, so that in this space that I'm dragging out, there's an infinite number of time breaks, and each time break has a three-dimensional body, and that makes up a four-dimensional space.

The difference between four-dimensional space and three-dimensional space is because there is more time.

You might say that time hasn't changed.

According to the theory of relativity.

The strong field bends space-time and slows down the inertial frame of motion, which is known as the bell slow effect.

In layman's terms, a moving clock moves slower than a stationary clock, and the faster it moves, the slower it moves, and when it's close to the speed of light, the clock almost stops, but what you see in front of it is squeezing towards a point in the middle, and that point is a wormhole. When you move faster than light, you go through the wormhole and see everything going backwards, like I said earlier about dragging the box, and you see that there's a time break where you're moving faster than light, and there's a box that's lost and falls back into a box.

=1/sqr(1-u^2/c^2)

t= (t+xu c 2), so t= ( t+ xu c 2), and x=0, (to be measured in the same place), so t= t

u is the velocity of the inertial frame, when u=c, there is no value, or it can be understood that it tends to infinity, that is, t is infinite relative to t, then the person in the coordinate system t is relatively stationary with the t coordinate system. This falls under the category of special relativity explanations, and the speed of light cannot be exceeded.

The landlord's point of view is right, whether the speed of light is faster than the speed of light, it can only slow down time, it is impossible to stop time, and it is impossible to go backwards.

Let's say the two of you race together, and for a second, you swoop across the globe, but the person doesn't stand still, and he does what he can do for a second, and he lowers his arm. It's even more impossible to do what was planted for a second.

When the speed reaches the speed of light, time stops. Faster-than-light time is reversed! This sentence is just an exaggeration of understanding, or a misunderstanding, and it is not a fact.

Just look at the theory of relativity for what it says about this.

I don't want to figure out who no one will teach you, go to see a brief history of time in Chinese I haven't seen this, at least I know what e mc2 means, and if I don't know, let's go to elementary school

At one point, scientists studied the possibility of transcending the speed of light, fantasizing about one day being able to build rockets that move faster than the speed of light. In this way, people can catch up with the light signals emitted on the earth by simply riding this rocket and thus see what happened on the earth in the past. This means that at the speed of light, time will be reversed, and people will pass tomorrow, today, and then yesterday.

In other words, a person becomes an old man first, then a young man, a teenager, and then a baby. This phenomenon is unimaginable for people living in our physical world.

As you know, if a missile is launched at the speed of a jet fighter flying at the speed of sound, and its speed relative to the aircraft is also comparable to the speed of light, then, in the eyes of people on the ground, the missile will fly forward at twice the speed of sound. This is a conclusion based on the synthetic formula of the velocity of classical physics. But if a beam of light is fired at a rocket traveling at the speed of light, will that light travel forward twice the speed of light for an observer on Earth?

This question was a headache for scientists at one time. It was not until the end of the last century, when American scientists Michael Sun and Morey collaborated on a famous experiment that gave a largely clear answer to this question. They confirmed such an important conclusion:

The speed of light in a vacuum never changes, regardless of the observation system in which it is measured, and whether or not the light source emitting the speed of light is in motion. This shows that the speed of light is the "absolute champion" of nature as we know it today, and it is the limit of movement. Therefore, time is never turned back.

In fact, sometimes the explanation is very simple, in space physics, space and time are closely related. I'll give you an example, and you'll probably understand why. Take sunlight as an example, because it takes 8 minutes and 23 seconds for sunlight to reach the Earth, in other words, the sun you see is always the same as the sun 8 minutes and 23 seconds ago.

Light travels at the speed of light, so in space physics, distance is sometimes expressed in terms of time, such as light years that you are familiar with. A light-year is a distance of light that has one year. There is both time and space in it.

All that's left is to solve the problem of exceeding the speed of light. You should draw a timeline, you are standing at this point, the sun is 8 minutes and 23 seconds ago, if it exceeds the speed of light, then you are not seeing the sun 8 minutes and 23 seconds ago? So if you exceed the speed of light, time will go backwards.

In general relativity, it is not allowed to exceed the speed of light.

The eye sees things through the reflection of light, if the speed is the same as the light, the reflection to our eyes is of course static, in the same way, more than the speed of light, the reflection speed of the eye can not keep up, then it is not regressive. But these are all speculations, things that have not yet reached the speed of light in reality.
