Our history engraved in the sky - total solar eclipse -

 The solar eclipse site of the "Three Kingdoms" was not on the Korean Peninsula, but how can a country find the best observation site from this record when it leaves a series of solar eclipse records? When an eclipse occurs, there is a moon shadow on the earth. In some places, you can see a total solar eclipse in which the sun is completely hidden by the moon. In the surrounding area, a partial solar eclipse occurs in which half a shadow of the moon is cast, and only a part of the sun is covered by the moon. If the moon deviates further from the sea, only a partial solar eclipse occurs. In either case, an eclipse can only be seen in any particular area on Earth. Talking about Northeast Asia, some solar eclipses can be seen on the Korean Peninsula and in the west, but not in the east, and some solar eclipses can be seen on the Korean Peninsula and in the north, but not in the south. Suppose a country consistently observed solar eclipses on the Korean Peninsula. Where can you best see all the solar eclipses recorded by the country? It is the Korean Peninsula. This is because among the solar eclipses recorded by the country, there are solar eclipses that cannot be seen or seen in neighboring countries. The optimal solar eclipse observation site is found using the properties of these eclipses. Then, where did the three countries actually observe the solar eclipse? If we can know this, we will be able to determine whether the three kingdoms really made their own astronomical observations and where they made their observations. First, in order to confirm the reliability of my method of estimating solar eclipse sites, I tracked the optimal observations for solar eclipse records left by Goryeo, Korea, Tang, and Yang countries and compared them with the powerhouses of each country. It could be seen that the results were actually consistent with the historically already confirmed stronghold This time, we looked for the best solar eclipse observation sites in the three countries. The location on Earth where all of the Japanese dishes contained in Three Kingdoms<Baekje Bongi> can be observed best is the Balhae Bay basin. In addition, the location where you can see the solar eclipse of Goguryeo, which usually appears in the 2nd and 3rd centuries A.D., was the area of northern latitude than Baekje, from Manchuria and Mongolia. Silla's eclipse records have been divided before 201 A.D. and since 787. Among them, the optimal observation site for Japanese food in Sangdae Silla before A.D. 201 was found to be the quantum river basin. The southern part of the Korean Peninsula was found to be the best observation site in Hadae Silla, which comes out after 787 A.D. In other words, in the Samguksagi, solar eclipses passing south in the early Silla period are mainly recorded, and solar eclipses passing north in Goguryeo and in Baekje, solar eclipses passing between them are recorded. This is a very unusual result. If China's records were copied, it would make sense if the best solar eclipse observations recorded by Chinese countries at the time and the best solar eclipse observations recorded by the three countries came out in the same location on average. However, as a result of analyzing the records of solar eclipses, the observation sites of the three countries are separated by very different latitude from country to country. What are the chances of such a result if the "Three Kingdoms Fraud" indiscriminately copied China's records? After Kim Bu-sik, the editor of Samguk Sagi, selected Chinese Japanese food records through high-level astronomical calculations, the Japanese food passing through the northern latitude was divided into "Koguryo Bongi", "Silla Bongi", and the one in between was inserted into "Baekje Bongi". This is because this level of calculation requires sophisticated astronomical knowledge and extensive numerical calculations using state-of-the-art computers. Therefore, it can be concluded that the solar eclipse records of <Silla Bongi>, <Gogury Bongi> and <Baekje Bongi> were independently observed in different regions. This can be proved by stochastic calculations. If you use a computer to randomly select Japanese food records from Chinese librarians and run thousands of simulations in <Silla Bongi>, <Goguryo Bongi>, and <Baekje Bongi>, you can see that there is virtually zero possibility of such a latitudes difference in the best observation sites of the three countries. The eclipse record of the Three Kingdoms is not an imitation of Chinese records, but a record that was measured at different locations. Meanwhile, even though Silla and Baekje observed solar eclipses on the Korean Peninsula, the probability that all the hardness of the optimal observation site "accidentally" will come out to the Chinese continent is virtually zero. (see previous published paper). Their solar eclipse records were measured not from the eastern part of China by chance, but from there. In short, looking at the solar eclipse observation sites of the Three Kingdoms, it can be seen that the existing conclusion that the solar eclipse record of the Three Kingdoms was copied from the Chinese side was a wrong judgment.
