The Tiangou Food Day on June 2 1 2020 is the most important astronomical phenomenon this year, which is really a good opportunity for astronomy lovers. So do you know what is the omen of Tiangou food day? What is the moral of the people? What's the point? Next, let's reveal the secret by constellation knowledge!

What is the omen of the dog eating the day? China's ancient science and technology were underdeveloped, and many things could not be solved by science. Therefore, the ancestors who advocated heaven, earth and ghosts invented some strange cultures, such as divination and astronomical phenomena. Tengu's eating day suggested ominous signs among ancient people. The ancients thought that if this phenomenon happened, it would indicate that the world was in trouble.

What is Tiangou Food Day? Today people call it a total solar eclipse. Total solar eclipse is a kind of solar eclipse, that is, an astronomical phenomenon in which sunlight in some parts of the earth is completely blocked by the moon. Total solar eclipse can be divided into five stages: initial loss, eclipse, eclipse, 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.

The significance value of total solar eclipse is paid attention to mainly because it has 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 these discoveries 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. When passing near the sun, it is impossible to see whether the faint starlight in the distance turns. However, if there is a total solar eclipse and the sun is blocked, it can be measured whether the light turns.

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. However, it represents an ultimate humanistic concern, an extreme love for nature, an eternal curiosity and awe of the iron law of nature that dominates everything, and it inspires all mankind to continue to advance on the road of exploring the universe.
