What is the omen of the dog eating day? What is the folk moral?

The Tiangou Food Day on June 2, 20201is the top priority of this year's astronomical phenomena, which is really a good opportunity for astronomy lovers. So do you know what is the omen of Tiangou food day? What is folk morality? What's the point? Then let the constellation knowledge reveal the secret for everyone!

What's the omen of Tiangou Food Day? Unknown omen.

China's ancient science and technology were underdeveloped, and many things could not be solved scientifically. Therefore, the ancestors who advocated the gods of heaven and earth invented some strange cultures, such as divination and astronomical phenomena. In ancient times, dogs eating the sun implied an ominous sign. The ancients thought that if this phenomenon appeared, it would indicate chaos in the world.

What is Tiangou Food Day?

"Tiangou Food Day" is called total solar eclipse today. Total solar eclipse is a kind of solar eclipse, that is, an astronomical phenomenon in which the sun is completely blocked by the moon in some parts of the earth. Total solar eclipse can be divided into five stages: initial loss, food, food, light production and recovery. Because the moon is smaller than the earth, only people in the umbra of the moon can see the total solar eclipse. Now people call it "the dog eats the moon", which is a unique natural phenomenon.

Importance value

The reason why the total solar eclipse is taken seriously is mainly because of its great astronomical observation value, because the moon will darken the original dazzling sun and expose the corona layer that was not easy to observe. Many important astronomical and physical discoveries in the history of science were made by the opportunity of total solar eclipse, and only through this opportunity can they be made.

The most famous example is a total solar eclipse in 19 19, which confirmed the correctness of Einstein's general theory of relativity. Einstein published his general theory of relativity in 19 15, which was extremely difficult and incredible at that time. This theory predicts that light will turn in a huge gravitational field.

The strongest gravitational field that humans can contact is the sun, but the sun itself emits strong light, so it is impossible to see whether the faint starlight in the distance turns when passing near the sun. However, if a total solar eclipse occurs and the sunlight is blocked, it can be measured whether the light has turned.

The opportunity appears in 19 19, but the total solar eclipse is in the South Atlantic, which is far away and difficult. British astronomer Eddington set out with an enthusiastic and curious observation team. The observation results are very consistent with Einstein's pre-calculation results, and the theory of relativity has been recognized by the world since then.

Astronomical phenomena such as total solar eclipse have nothing to do with people's daily life. Eat and drink Lazar. But it represents an ultimate humanistic concern, an extreme love for nature, an eternal curiosity and awe of the iron law of nature that governs everything, and it inspires all mankind to continue to move forward in the exploration of the universe.
