The discovery of Neptune and Pluto tells us the inevitability of the existence of the Xia Dynasty

In the solar system in which we live, there are eight planets orbiting the star Sun, from near to far, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and a special planet, Pluto, which also existed as a planet in the solar system, was kicked out of the solar system in 2006 and classified as a dwarf planet.

Xia Shang and Western Zhou, Eastern Zhou divided into two sections, Spring and Autumn and Warring States. This is a list of Chinese dynastic sequences that we have memorized since we were young when we were in school and remembered. Because the archaeology of the Xia Dynasty has not been clearly documented, it has been suspected and criticized by western elites and some Chinese people.

However, what I want to tell you is that from the discovery of Neptune and Pluto, it can be proved that the existence of the Xia Dynasty is inevitable!

Neptune and Pluto, high above the stars, are hidden in the endless galaxy; the Xia Dynasty, buried deep in the ground, hidden in the unknown surface of the earth. How can there be a connection between the two? And listen to @ Three Ways of History for you to shred, heaven and earth people, Confucian Interpretation, new perspective to decipher history ~

01 Discovery of Neptune

Speaking of Neptune, we have to mention its predecessor, Uranus.

For a long time, people have thought that the solar system has only 6 major planets, gold, wood, water, fire and earth. The ancients looked at the stars at night, pinched their fingers, and there must be other members of the solar system hiding in the endless starry sky, waiting for human discovery.

If a worker desires to do a good thing, he must first use it. To observe the starry sky, it is impossible to do it with the human eye alone, and the discovery of astronomical telescopes has compensated for this shortcoming.

In 1609, the Italian scientist Galileo Galileo heard about the discovery that two lenses could be stacked together to clearly see things in the distance, and immediately made the first astronomical telescope in human history to observe the starry sky.

In 1663, the Scottish astronomer Gregory used the principle of light reflection to make Gregory mirrors, but due to the immature production process, it did not become popular. In 1667, the British scientist Newton improved Gregory's idea and made a Newtonian mirror. In 1672, the Frenchman Cassegreen used concave and convex mirrors to design the most commonly used Cassegreen mirrors. This telescope has a long focal length and a short mirror body, a large magnification and a clear image; it can be used to study celestial objects in a small field of view and to photograph large areas of celestial objects.

On March 13, 1781, the astronomer Herschel brothers and sisters discovered a new object with a pale blue, planetary-like small round face with a homemade 15-centimeter mirror, which he initially firmly believed to be a comet.

But the orbit of this new object is almost perfectly round, and its orbit is farther than Saturn, which is a new planet!

Later, the Berlin astronomer Johann Peter raised doubts that he thought Uranus was a planet, but he failed to prove his suspicions, and finally the French astronomer Laplace proved that Uranus was a new planet in the solar system by calculating the trajectory.

This is the first time that human beings have discovered a new frontier of the solar system after the five stars of the sun and moon. The new planet was named Uranus by European astronomers after the god in charge of the celestial realm in Greek mythology.

Uranus is 4.06 times the diameter of The Earth and 14.63 times the mass of the Earth, and Uranus is 19.2 times the distance from the Sun.

The discovery of a new planet in the solar system, a major event not seen in thousands of years, astronomers were very excited and began to study the orbit of Uranus.

However, astronomers have found that this "young" planet, some young people do not talk about martial virtue, do not go on the right path, and often go astray. Because the six planets of Jinmu, Water, Fire and Land all follow the orbits calculated by scientists around the sun, only Uranus is a little restless, and when it orbits the sun, it always deviates from the route it should take.

At this time, Newton's gravitational force has been accepted by scientists, and astronomers speculate according to universal gravity: there must be another planet near Uranus that exerts gravity on Uranus and disturbs the orbit of Uranus.

However, these are all conjectures, how can they be proved? Where is this unknown planet hiding? How to find out? For a while, astronomers were sad, where did the planet go?

At this time, mathematicians began to come out to help. In 1845, the Frenchman Auburn Le Vier and the Englishman John Cauchy Adams began to calculate the orbit of this unknown planet to determine the nature and position of such a planet, and it is said that the two calculations also triggered an academic competition in the British and French academic circles!

On September 23, 1846, the German astronomer Galler observed the planet with a telescope, which is Neptune.

Neptune's distance from the Sun averages 4,498 million kilometers, which is equal to 30.09 times the average distance between Earth and the Sun. It is slightly smaller than Uranus, with a diameter of 3.88 times that of Earth and a mass of 17.22 times that of Earth.

02 The existence of Pluto

After the discovery of Neptune, astronomers began to observe its orbit intensively, and it turned out that this newly discovered planet copied its predecessors, not to mention Martial Virtue, neptune's orbit is also irregular, completely unobtrusive, romantic by nature, and debauched!

At this time, astronomers have experience, and have speculated that there must be another planet on the periphery of Neptune, affecting the operation of Neptune.

However, this possible planet is really too naughty, although astronomers have used mathematics to calculate its position in the sky, but using astronomical telescopes to find this unknown hidden in countless stars in the endless starry sky is undoubtedly a huge project, and astronomers have spent decades still unable to find its trace.

History is always a striking coincidence, similar in reincarnation. On March 13, 1930, the American astronomer Tombaugh took many pictures of stars in succession according to Lowell's calculations, and when examining these photos, he found that there was one star in it, and found that there was one star in it, and the position was shifted. So Tombo concluded that this was a new planet in the solar system. Because only a planet will constantly move its position in the sky. In this way, a new planet was discovered, which is Pluto, and this day is exactly 149 years after the discovery of Uranus!

Pluto is so far away from the Sun that it is difficult for astronomical telescopes to observe it, the average distance from the Sun is 39.5 times the average distance between the Earth and the Sun, but its mass is only 0.24% of the Earth, the orbital period around the Sun is 248 Earth years, and it was kicked out of the solar system in 2006.
