Why did the ancients say that there is one day in heaven and one year on earth?

Obviously, there would have been no scientific theories about the effect of time dilation in ancient timesHowever, the ancients were much more sensitive to astronomical insight than modern people, because the bright starry sky was one of the few things they could use to let their imagination fly, and they had more time to look up at the starry sky than modern people. According to the 12 branches, the ancient Chinese ancestors introduced the movement and changes of the moon, the sun and the stars, formulated a calendar, and even accurately determined the number of days in a year.

In fact, in the ** of "Journey to the West", the saying "one day in the sky, one year on the earth" also runs through the whole book, for example, Sun Wukong was recruited to the upper realm to be Bi Ma Wen, and later learned that this was a sesame petty official, so he went down to Nantianmen and returned to Huaguo Mountain.

When the monkeys greeted him, they said: "Congratulations to the king, you have been in the upper realm for more than ten years, and you must be proud to return?" "The Monkey King said:

I've only been there for more than half a month, and I've been there for more than ten years? The monkeys said, "O king, you are not aware of the hour in heaven."

One day in heaven is a year in the lower realm. ”

In fact, this relativity of time extends to all things in the universe. Just as the Buddhist "Nioh Sutra" says: "A flick of the finger refers to sixty moments, and one moment is nine hundred births and deaths", and the very small unit of time also contains countless births and deaths.

And life is between heaven and earth, and the seemingly long life is like a white horse passing by, suddenly. It's just that we, like everything in three-dimensional space, can't break through the limitations of this time and space, and can't jump out.

This is related to the rotation and revolution of the earth, and the earth revolves around the sun, and one revolution is a year.

Because the ancient legends are like that, time in the heavens passes very quickly, and time on earth passes so slowly, so it is like that.

This statement is only found in mythological stories, probably because the earth rotates for a year.

This is an ancient myth and legend, or maybe it is because the earth revolves in a year.

Because the ancients thought that the time of the earth is longer and the time in the sky is shorter, which is related to the rotation and revolution of the earth.

It may be that time on other planets is slower than that of Earth, so it is possible.

I think this may be just a rumor, and over time I believe it.

This may be a myth at the time, that's why I say that.

It's just a legend in folk mythology, it's not true, it's people's imagination.

They mainly understand based on the displacement of the moon, we look at the earth, the rotation of a moon from the moon will have a cycle, and it will return to its original position in a year, so we came up with such a theory.

It may be because the earth changes very quickly, and people tend to grow old, which is what makes them have such a view.

It is related to ancient myths and legends, and there are many myths and legends in ancient times, so there is such an idea that it is also related to the movement of the stars.

In some mythical TV, we will often hear the words of the gods saying that there is a day in the sky and a year in the earth, and in those myths, people believe in such words very much, but as we said, flies do not bite eggs, there must be someone who has issued such a point of view before people say,So why do you say that one day in the sky is one year underground? Is there any basis for this? Because the speed of the earth's revolution is different from that of the sun, and some people will borrow this idea to say that there is one day in the sky and one year in the earth, which also contains a certain scientific basis.

A day in the sky is a year in the earth, this sentence is what we often hear when we watch costume ** or costume dramas. There is no basis for this, it is all imagined by people who write about ancient costumes.

In fact, there is no basis for this, this is just a difference between the heavenly time and the underground time set in ancient myths and legends, and there is not much scientific basis.

This is only a comparison made according to the rotation speed of the stars, not a real difference in time, a pure comparison in space, so it is not true, and those rumors that travel through time and space in the future can not be believed, and time and space cannot be crossed at the same time, there is no basis at all.

The ancients knew that "one day in the sky and one year in the earth", of course, it was a coincidence! Because of the shrinkage effect and time dilation effect of modern physics, many people can calculate that if there is a flying boat flying from the earth to Andromeda 2.8 million light-years away, the spacecraft can reach Andromeda in 8-9 years, but 280 years have passed on the earth, and it is really "one day in the sky and one year underground". Therefore, it is said that the ancients also understood the stars of the universe, and even understood the theory of relativity and quantum mechanics.

In fact, the earliest legend is that two people who look like Taoist priests are playing chess with sheep, and then when the chess is finished, the sheep herd finds that his sheep shovel and decay.

China was due to the strong hindrance of Confucianism after the Song Dynasty. Therefore, after the Ming Dynasty, when we were obsessed with using the Bagu Wen to select the so-called talents who only spoke of morality, the West was already in the midst of a Renaissance. Later, in the last years of the Ming Dynasty, when science had been developed in the West, we still believed that "as long as the moral level is high, all problems can be solved".

Now when we see everything in the universe discovered by modern science in the West, those who shake hands say that we have discovered it a long time ago, which is irresponsible and even a little shameless!

It means that there is a difference between the time in heaven and the time on earth, and a day in heaven is equivalent to a year on earth, and I have found several explanations:

1.Myths and legends come from it, and it is not credible.

There is a fable about a fisherman who was about to freeze to death, and at this time the fisherman ascended to the sky, and the wine and food were singing and dancing, and the fisherman lived in the sky for 8 days, and he was very happy. On the 8th day, the fisherman misses his family and decides to return to the world, so the gods help the fisherman return to the world. When the fisherman returned to the world, he found that 80 years had passed.

Happy times always feel short-lived, and they pass quickly; The painful times are long, and it feels like they pass slowly.

Heaven is a symbol of happy times, and on earth is a symbol of painful times.

2.Einstein's theory of relativity has an explanation and is credible.

If you are fast enough in the heavens, according to the principle of relativity, you can do it for one day in the heavens and one year on earth.

According to the relativistic theory of time dilation:

Let the passage of time you feel as t'

The passage of time is t when at rest

The speed of light is c and your speed is v

Then according to the formula:

t'=t root number (1-(v c) 2).

Then after the calculation, it is known.

t = 86400 seconds.

t'=86400*365 seconds.

c = 3 * 10 8 meters per second.

So v = meters per second.

At this point your mass is close to positive infinity due to relative expansion.

And humans can't accelerate an object as big as a human to that fast (close to the speed of light), so in theory it's possible, but in practice it's not.

At present, humans can only speed up some elementary particles to a few percent of the speed of light, and no matter how large they are, it is basically impossible.

Because it can be obtained according to f = ma (f force, m force mass, a acceleration) when the mass is close to positive infinity, it is very difficult to obtain a large acceleration and the speed cannot be increased, and naturally it cannot exceed the speed of light, so at the same time, time travel is also impossible.
