What is the slow clock effect, what is the shrinkage effect and the slow clock effect?

The bell slowness effect. Also known as time dilation, Einstein.

Delay is the special theory of relativity.

An important conclusion. According to the theory of relativity, this is because the motion of the object slows down time. This is not the case.

According to the unification mechanical model, a formula for time variation can also be derived, which is exactly the same as the formula for the "bell slow effect", i.e., t=t. However, it represents the "displacement" of (t -t) in the time dimension when a being moves, which corresponds to the displacement of the being in the space dimension. Not only that, but the unification theory finds that there is also a "displacement" in the mental dimension when the being is in motion.

In the theory of unity, the "clock-slow effect" is expressed as the "time position theorem". The specific calculation method: where t0 is the original time, v is the velocity, and c is the speed of light.

From the formula, it can be seen that when v gradually increases, t gradually increases, and the time gradually expands. Therefore, some people speculate that time stops when v=c, which is also the origin of the inference that "if your speed exceeds the speed of light, time will go backwards". Since the speed of light cannot be reached, time can never be turned back.

Gravitational field. It has a damping effect on the operation of atoms, and the energy is consumed in the form of gravitational waves.

In a gravitational field, the velocity of atomic energy consumption is directly proportional to the speed of the atom and inversely proportional to the strength of the gravitational field. What objects move autonomously in the gravitational field, when the velocity is greater than the gravitational force.

The acceleration effect is damping by the gravitational field. It takes the form of deceleration, and the energy exchange method is gravitational waves. Any time that the velocity of matter in the gravitational field is less than the gravitational acceleration effect, it will be dragged by the gravitational force, which is expressed in the form of acceleration and energy in the form of gravitational field stretching.

It can also be shown that the bell slow effect is the damping result of the gravitational field, which is directly proportional to the speed of the clock, and the faster the speed, the more obvious the bell slow effect.

When it comes to the special theory of relativity, many people immediately think of the phenomenon of clocks moving slowly and rulers shortening. Many science fiction works use it as a subject matter, depicting a man who returns from a rocket trip to space, only to find that he is still very young and that his grandson has become an old man. In fact, the slow movement of the clock and the shortening of the ruler are only one of several conclusions of the special theory of relativity, which refers to the fact that when the object is moving at high speed, the clock on the moving object slows down and the ruler becomes shorter.

The slowing down of clocks and the shortening of rulers are the result of the change of time and space with the movement of matter. Special relativity also concludes that mass increases with the speed of motion. In the experiment, it was found that the mass of electrons moving at high speed is greater than that of electrons at rest.

Einstein proposed the "clock slow effect", where faster-than-light time slows down? Let everything be changed!

Clock slow ruler shrinkage: also known as slow ruler shrinkage. According to Einstein's special theory of relativity, especially the assertion that the clock is slow and slow in it.

When an object is moving at a speed close to the speed of light, time around the object slows down rapidly and space shrinks rapidly.

When the speed of motion of an object is equal to the speed of light, time stops and space shrinks to points, i.e., zero space-time appears. Only objects with zero rest mass can reach the speed of light. No object can exceed the speed of light.

According to the special theory of relativity, space-time also has a Doppler effect, and the slow shrinkage of the clock is a manifestation of this effect.

When an object is moving close to the speed of light, time around the object slows down rapidly and space shrinks rapidly. When the speed of light is reached, time stops and space shrinks to zero. This effect is so subtle at low velocities that it cannot be detected or detected, and is only noticeable when it approaches the speed of light.

Therefore, people on the light-speed spaceship do not feel that time is slowing down, but they just don't take time, because the space has become 0, and they don't leave, how can they feel the passage of time? And those who observe from the outside, who are not in the same inertial frame of reference as the people in the spaceship, can feel that their time passes very slowly. By the time the spacecraft had circled 100 light-years away, 200 years had passed on Earth, and the people in the spacecraft felt like they hadn't taken time.

But the world photons are able to reach the speed of light because the photons do not stop, so there is no rest mass, only moving mass. The momentum of the photon is p=h =hv c, where v is the frequency, is the wavelength, c is the speed of light, and h is Planck's constant. Planck's constant is:

h= j·s。

The bell slowness effect. It is a physical phenomenon: between two identical clocks, the person holding the first bell will find that the second clock is slower than his own. This phenomenon is often said to mean that the other party's clock "slows down", but this description will only be in the observer's frame of reference.

is correct. Any local time moves at the same speed. The time dilation effect applies to any process that explains the change in the speed of time. The shrinkage effect generally refers to the shrinkage effect of length.

The length shrinkage effect is one of the relativistic effects. The length of a stationary long rod can be measured with a standard ruler and moves in a straight line at a uniform speed in the direction of the rod.

If you want to know its length, you have to note the spatial position of both ends of it at the same time. The distance between these two spatial locations is defined as the length of the moving pole. Special relativity.

As a foreshadowing, the length of a pole moving in the direction of the pole is shorter than the length of the pole when it is at rest. This effect indicates the relativity of space.

Space flight and time dilation.

According to the time laugh wide expansion effect, the astronauts are relative to the observer on Earth.

When moving inside a spacecraft at extremely high speeds, for Earth observers, the people inside the ship have not aged much despite the long years that have passed on Earth, as the extreme speed slows down the time of the spacecraft (and all objects inside).

That is, an observer on Earth will notice that by the time the ship's clock has gone one turn, the clock on Earth has already made many turns. As long as the speed is high enough, this effect will be noticeable. For example, for an observer on Earth, it may have been ten hours, but a space traveler's watch has only been an hour.

This effect affects both the spaceship and the Earth.

It is symmetrical, because the Earth sees the spaceship moving, and the spacecraft sees the Earth moving, and the velocity of the attitude rise is equal.

Speaking of the bell slow effect, we also need to talk about the theory of relativity.

The consciousness of relativity is simple, it is relative. After B is in motion, A is also in relative motion for B. So regardless of the acceleration process, when two people move relative to each other, the clock for A to see B slows down and the clock for B to see A also slows down.

So if two people see each other again and are relatively still, the clock will become the same again. Another premise here is that both of them must be in a closed energy system, and both acceleration and deceleration are paying the same amount of energy. The change in relative energy is what causes the change in time.

According to the theory of relativity, time does not flow at a uniform speed, but is determined by its own speed of motion. The faster you move, the slower you will be relative to others. In this way, you will reach the future faster.

Therefore, if you live in a tall building, then because of the rotation of the earth, you will be faster than the person living in a low building, because in the same time, the amplitude (radius) of motion is larger, the speed will be faster, then your time will be slightly slower relative to others, just a few tenths of a nanosecond.

So if you reach the speed of light and sit in a spaceship, then the people outside watch you take a sip of water, and before you can see half of it, the people outside are dead. Therefore, if the speed is infinitely close to the speed of light, time will almost stand still relative to people from the outside world, and its own mass will tend to be infinite. If your speed reaches the speed of light, then time will stand still completely, the mass will be infinite, and the next second will never reach it, and you will come to the end of time, and you will die, so that anything other than light cannot reach the speed of light.

Through this principle, it can also explain why time on artificial satellites is slower than our daily time, because the distance from the ground is fast, and the speed of time passage slows down.

Another implication is that if the speed exceeds the speed of light, then you will go back in time, because you will catch up with the light from the previous second, and at the same time see the scene of the previous second, and then look at the earth again, it will be a movie backwards. But the universe is inconclusive that it is impossible to reach the speed of light, let alone exceed it, this is only the imagination of human beings.

The theory of relativity derives the relationship between the time schedules of different inertial frames, and finds that the time progress of the moving inertial frames is slow, which is the so-called clock-slow effect. It can be popularly understood that a moving clock moves slower than a stationary clock, and the faster it moves, the slower it goes, and when it approaches the speed of light, the clock almost stops.

The length of the ruler is in an inertial system"At the same time"The difference between the coordinates of the two endpoints obtained. Due to"At the same time"The length measured in different inertial frames is also different. The theory of relativity proves that a ruler moving in the direction of its length is shorter than a ruler at rest, which is known as the shrinkage effect, and when the speed is close to the speed of light, the ruler shrinks into a point.

Einstein proposed the "clock slow effect", where faster-than-light time slows down? Let everything be changed!

No matter which inertia system people in it, they think that the other party's clock is slow! Both of them are right, and it has nothing to do with the direction of velocity. Only when you still think about the problem in terms of absolute time will you think that they can't all be right, and you will think that there is a contradiction, but in fact they are both right, and this will not bring any logical and practical contradictions!

Remember, there is no absolute question of speed or slowness of the clock, only a question of whether it is fast or slow relative to whom, this is the relativity of time!

Again, the observer in the theory of relativity and the inertial frame in which it is located are important, and when we describe a phenomenon, we must be clear about which observer is saying it, and which inertial frame the observer is at rest relative to (leaving aside the non-inertial frame involved in general relativity). If one of the two is not clear, the description may be meaningless; If neither is clear, then the description is certainly meaningless.

The descriptions of different observers can be very different, but they are not inherently contradictory, and they can be "translated" into each other through the Lorentz transformation. It's like a cube that looks straight from one side to the side and looks like a square, and one angle turns it into two rectangles, and another angle can be three diamonds. Which pair of these three different shapes are described?

All right! The transformation of the angle of rotation here is similar to the effect of the Lorentz transformation described above.

In the twin paradox, the ship has to undergo an acceleration process, while the younger brother who remains on the ground is always in an approximate frame of inertia. The younger brother can explain that the older brother is younger than him by using the knowledge of special relativity, while the older brother in acceleration must use the knowledge of general relativity to explain the same thing. The older brother who rode the rocket explained his youth like this:

When he did the exercise at a constant speed, he saw that his younger brother was getting younger; Although he was in an extremely strong equivalent gravitational field at the time of departure and landing, because he was very close to his brother at that time, the gravitational potential of the two was not much different, and the difference between their clocks during these two phases was ignored in the estimation. When he makes a U-turn, he is also in an extremely strong equivalent gravitational field, he is very far away from his brother at this time, and the gravitational potential he is in is much lower than the gravitational potential that his brother is in, and he will see his brother age rapidly. Combining the various stages, the younger brother is older.

The problem of twins, the two are opposite, younger than each other. It is a fallacy that people call a paradox in order to justify the theory of relativity. Actually, it's true.

This is not possible. Because he violated logic. However, this does not affect the relative correctness of the relative round.

You and he both have a watch, and when he moves, you read (if you can't see it) that his watch moves slower than yours.
