A blood moon that only occurs once in a hundred years, if it appears in ancient times, what worries

Science and technology were not developed in ancient times, and people felt that it was a bad phenomenon and thought that there would be wars because they felt that red was like blood.

The blood moon is actually a normal natural phenomenon, which is what we call the tengu eclipse moon, which actually does not have any special meaning, and it is only because the ancients did not understand it that they would have such a thought.

Ancient Chinese records: What is the sign of a blood moon.

In ancient times, the blood moon was generally considered to be a very ominous sign, for example, the ancient Chinese Taoist books said that the red moon is the most yin and cold, indicating that the world is weak in righteousness, evil is strong, resentment is strong and angry, the appearance of the blood moon is drastic, the mountains and rivers are sorrowful; In Indian Buddhism, a blood moon is a sign of impending disaster. The Bible says that when there is a blood moon, it is a sign that the end is coming. According to relevant records, there are indeed some major events that "coincide" with the appearance of the blood moon.

Here's what happened when a blood moon appeared on the historical crack scale:

1. On May 18, 498 A.D., after the blood moon phenomenon occurred, the great Sima Wang Jing began to rebel.

2. On September 6, 499 A.D., Xiao Yaoguang, the king of Shi'an, who rebelled, was defeated and died. Hidden.

The ancients interpreted the Blood Moon as a bad omen, and the rising of the Blood Moon was likely to cause calamity. In other words, according to the understanding of the ancients, the blood moon is a "fierce silver digging moon", which is a bad omen, and the rising of the blood moon is likely to cause disasters. For example:

The Book of Nanqi records: "Emperor Yongtai of the Ming Dynasty in April of the first year, the lunar eclipse, the color is red like the core of the blood wheel, and the three days and the great Sima Wang Jing raised troops."

From the point of view of the formation of the blood moon, the blood moon is actually a natural landscape, but it is not common. Usually, the occurrence of a Blood Moon is associated with a lunar eclipse, but forest fires can sometimes trigger a Blood Moon. This is because after a forest fire, a large amount of smoke and dust will drift into the sky, and when the sun's purple, green, yellow and other shorter wavelengths of photons encounter these smoke and dust, they will scatter.

Causes of Blood Moons.

In addition to wildfires, the most common "blood moon" is actually a lunar eclipse, especially a total lunar eclipse that causes the moon to turn red. When the Sun, Earth, and Moon orbit in the same plane, where the Moon is between the Sun and the Earth, the Moon blocks the Sun's rays from reaching the Earth, thus forming a solar eclipse.

The red photons in sunlight have the longest wavelength and the strongest ability to penetrate the atmosphere, so when a total lunar eclipse occurs, only the red photons will be refracted to the moon, and the moon will reflect the red photons back to the earth, and the moon we see will turn red, which is the "blood moon".

In ancient times, the turning of the moon into red was a bad omen, and the ancients would have been frightened when they saw a blood moon. Because the ancients believed that "heaven and man are one", an abnormal situation in the sky represents the earthly hunger and good fortune.

In fact, the turning of the moon is just a natural phenomenon, but the ancients did not have so many scientific instruments to observe the earth, and there was no way to find out the real reason why the moon turned red.

Total lunar eclipse and blood moon

In fact, the occurrence of a total lunar eclipse will inevitably be accompanied by a "blood moon".

If the earth is regarded as the center, then the sun and the moon both move around the earth, but because the orbit of the sun around the earth and the orbit of the moon around the earth are not on the same plane, the can can be hidden and do not block each other most of the time.

When the sun, the earth and the moon are in the same plane, there will be solar eclipses, lunar eclipses, etc., because of the mutual occlusion of the planets, among which the lunar eclipse is divided into a semi-lunar eclipse and a total lunar eclipse, and the most ornamental value is the total lunar eclipse, because not only can you see the process of the moon being occluded by the earth, but also you can see the formation of the "blood moon".

"If the moon changes color, there will be calamity. Green is worried about hunger, red is fighting and fighting, yellow is virtue and joy, white is drought and mourning, black is water, and people are sick and die. "It is rumored that the appearance of the Blood Moon is a great omen, and a major disaster will occur, and whoever sees it will be unlucky.

In fact, this statement is feudal superstition. There are many legends and stories about the blood moon, but none of them are true and cannot stand up to scrutiny, which is just an explanation of the blood moon that appeared when science was not developed at that time. It's not that the Blood Moon can't be seen, and it won't be good if you see it.

The Blood Moon is a very special natural phenomenon, but in ancient times or some religious legends, it was believed that the appearance of the Blood Moon would be very terrifying. Therefore, the ancients were extremely afraid of the phenomenon of the blood moon, and the terrible legends about the blood moon were handed down among the folks.

An ancient Chinese Taoist book once recorded: "It shows that the righteous spirit in the world is weak, the evil spirit is strong, the resentment is strong, and the anger is strong; The wind and clouds change drastically, and the mountains and rivers are sorrowful; The world is in turmoil, and fires are everywhere. "The general meaning is that when the blood moon appears, there will be a catastrophe. Since then, this idea has been passed down continuously.
