A thousand-year-old book was unearthed in Hunan. Why do the research results make western scholars dumbfounded?

China is a country that has attached great importance to astronomy since ancient times. I ching wrote: look up at astronomy and look down at geography? It shows that people in China have been studying astronomy for a long time. In fact, as early as the Yaodi period, China had already started. Yao Dian records:

Xi He was ordered to respect the sky, like the sun, the moon and the stars, and to respect the people. Life is divided into two parts: West China, Zhai Yi and Legu. Yin Bin is away from home. He works in the East. ?

However, most of these astronomical expressions are literary and artistic, and some mysticism has been added during the period, because these astronomical knowledge is related to production practice and? Imperial power? Taken together, it shows an incredible incredible. Many people didn't recognize the development of astronomy in China at that time, thinking that these were just? Superstition? That's all. It was not until a thousand-year-old wonderful book was found in an ancient tomb in Hunan that the whole world was surprised by the ancient scientific and technological level of China. Western experts shouted: this is impossible!

Mawangdui Han Tomb in Hunan Province is a famous ancient tomb. From 1972 to 1974, archaeologists have successively excavated three ancient tombs of the Western Han Dynasty here. Many cultural relics that shocked the world have been unearthed in this ancient tomb, such as the famous Mawangdui female corpse, the Warring States military strategist's solo book, and the health-preserving prescription, which have never been found before, providing sufficient information for the study of China's ancient culture and technology.

Unknown, a wonderful fortune-telling book called Five Stars was also found in Mawangdui. The study of the unknown and destiny has been the pursuit and yearning of mankind since ancient times, and the ancients are no exception. There are many ways of ancient divination, such as divination with grass as the medium, divination with tortoise shell as the medium, divination with horns as the medium and so on. Divination itself is a superstitious activity, but a lot of knowledge involved in divination is of scientific value.

For example, this 8000-word five-star book was discovered by archaeologists from Mawangdui tomb at the end of 1973. It is written on cloth and silk, so it is also called Mawangdui five-star book. Although Wuxing Zhan is nominally a fortune-telling book, its main content is based on astronomy, so we can call it an astronomical work. The knowledge of ancient astronomy recorded in Wuxing Zhan is completely beyond modern people's understanding of ancient astronomy.

The rendezvous period of Venus given in Five Stars is 584.4 days, which is only 0.48 days longer than the value measured today, and the error is only a few ten thousandths. The rendezvous period of Jupiter given by five stars is 377 days, which is only about 1 day worse than the current data. At the same time, the constant week of 30 years is given. For example, the current observation value is 29.46 years, only 0.54 years away. These data, whether relatively old or relatively modern, are shocking, because the same research in the West achieved such accuracy, far later than the five-star writing period. So western experts shouted: this is impossible!

Not only that, Wuxing Zhan also recorded a large number of astronomical phenomena related to historical facts at that time, which provided a lot of evidence for future generations to understand the social phenomena and scientific level at that time. The book records the running positions of Jupiter, Saturn and Venus in 70 years from the first year of Qin Shihuang (246 BC) to the third year of Emperor Wen of Han Dynasty (that is, 177 BC), and records them in detail in tabular form. It can be seen that people's persistence in scientific research at that time changed two dynasties (Zhou Dynasty changed to Qin, Qin changed to Han), but this kind of scientific research did not stop, which really shocked the spirit of the ancients in pursuing truth!
