Special relativity holds that the concept of simultaneity does not exist. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Time is a physical quantity that should be as simple and ordinary as other physical quantities such as length, velocity, mass, temperature, and so on. However, because it is related to the birth, aging, sickness and death of human beings, blessings and misfortunes, it has been given too many mysterious meanings.

People are in awe of time, because with the passage of time, people will gradually grow old, and finally die, disappearing from this heaven and earth. In a sense, time represents everything that human beings have, so much so that when it comes to a time-related problem, people's brains will subconsciously increase the importance and difficulty of the problem by an order of magnitude, which is an instinctive reaction.

But time is actually not that magical, its essence, like the length, speed, mass, temperature, just like the previous one, is just a physical quantity.

Going back to the original proposition, the theory of relativity holds that the concept of simultaneity does not exist. This is actually the result of a corollary, initially, when Einstein had not yet established a theoretical framework for the theory of relativity, Newton's absolute view of space-time ruled the world, or the earth.

Newton believed that the time of the whole universe is fixed and unified, and behind the cosmic scale, there is a fixed frame in the background of the universe, which marks the time of the whole universe, and everything in the universe runs harmoniously and perfectly under the control of this clock.

However, there is an experimental conclusion that makes this theory paradoxical, that is, the speed of light does not change, and at this time, this is only an experimental result, and no theory has yet been formed. Light is the fastest propagating in this universe, and if we follow Newton's view of absolute space-time, the speed of light measured by people walking towards light should be different from that measured by walking with light on their backs, because the speed of walking needs to be added or subtracted. However, the result of the experiment is that the speed of light is the same no matter how one measures it.

This challenged Newton's absolute view of space-time, and of course, Newton had already hung up at that time, so he could not express his position or explain why his theory contradicted the experimental results. So scientists tried to unify the results of this experiment into Newton's absolute space-time system, but found that it could not be done anyway.

For decades since, scientists have been doing this, but to no avail. When everyone was at a loss, Albert Einstein made a shocking idea that the speed of light is absolute, and that the speed of light is always constant in any reference environment, which is a constant in this universe.

There are many constants, such as Newton's law of gravitation, the gravitational constant G is a constant. However, it never occurred to people to make the velocity of an object a constant, which seemed to people at the time to be a fallacy.

According to the point of view established by Newton's mechanics system, as well as people's common sense, velocity is always relative, when you say how much a person's velocity is, you must find a reference, otherwise where the velocity comes from, you can say that he is stationary.

But Einstein said that the speed of an object is a constant in the universe, which is simply appalling, and it is the idea that it should be sent to eighteen layers of hell. But one has to admit that the previous experiment somehow validated this idea.

Starting from this theory that the speed of light does not change, Einstein gradually deduced a series of even more shocking theories of terror, yes, terror theories.

One of them, relativity at the same time, is only a small branch of the special theory of relativity, but its implications are so frightening and shocking.

According to normal people's thinking, the concept of simultaneity is undoubted, and even when speaking, it involuntarily carries the meaning of simultaneity. However, Einstein's theory denied this common sense, arguing that every object has its own clock, and that the clock flow rate is different from one object to another, which completely shattered Newton's absolute space-time framework.

Light can transmit information and energy, and the fastest way for people to observe the state of an object is through light, but light has speed, that is, there is a delay in a person observing the information of an object in other locations. This means that the order of observing the same event from different locations may be completely different.

There is nothing difficult to understand if you just get here, after all, light has a speed of propagation, and the time it takes to reach different locations will naturally be different, so it is normal to be assumed to occur one after the other.

However, if two people with different speeds pass by the same place when the clock is pointing to the same time, observe the same two things, and observe the same difference in the progress of events, this is where Einstein's theory is frightening. Because if the difference in the progress of two events is extremely large, then the cause and effect of the event may be reversed. This was a complete violation of human cognition, and at the time, it was fundamentally anti-human rhetoric.

However, Einstein then proposed that because of the upper limit of the speed of light, the speed at which two things with a causal relationship interact cannot exceed the speed of light, so the causal relationship cannot be reversed, but even so, this theory is still extremely appalling.

Thus, while this theory is logically unassailable, the Nobel Prize has never been awarded to this great scientist for many years because of its appalling conclusions.

However, because of the theory of relativity, Einstein's prestige in the physics community has been so high that even the Nobel Prize can not be ignored, so the Nobel Prize committee at that time had to come up with an extremely obscene and not embarrassing trick, and they awarded the prize to another theory proposed by Einstein - the law of the photoelectric effect. Therefore, although such a super-theory was proposed, and even any inference of the theory of relativity could win a Nobel Prize, Einstein did not win a Nobel Prize for it.

However, in the past 100 years, as various inferences of the theory of relativity have been verified by experiments one by one, the correctness of the theory of relativity has become more and more accepted. The theory of relativity about simultaneity has also been proven.

But there is such a group of people in the main god space, they can not observe objects through light, but use a power called psychic power to observe.

For a long time, Qiming has subconsciously ignored a problem, that is, the way of transmitting information by spiritual power is different from light, it is real-time.
