When the solar system was just formed, the moon was pulled by the earth and became its satellite. In the process of being brought closer to the earth, the moon once had a great influence on the earth. When the moon approaches, the ocean on the earth's surface appears strong tidal fluctuations, and the huge friction generated by this fluctuation makes the earth's temperature rise sharply, leading to the melting of the center of the earth. Under the action of high temperature and high traction, the magma in the center of the earth rolls in a rotating way, resulting in a magnetic field. This "super giant" magnetic field has formed a "protective shield" for the earth, reducing the invasion of cosmic rays on the earth. The survival and growth of life on earth depend on the protection of this magnetic shield. Without this protective shield, foreign radiation would kill all the seedlings of life that first appeared on the earth, and it would not reproduce on the earth at all. Not only that, the moon is quietly promoting the growth of everything. In the moonlight, plants grow fast and well, especially plants that are several centimeters high and germinate quickly, such as sunflowers and corn. The change of the moon phase also affects the sowing of plants. Carrots, white radishes, tomatoes, celery and Chinese cabbage are suitable for sowing in the first quarter, while eggplant, onions, leeks and pumpkins are suitable for sowing in the new moon.

Scientists also found that the relationship between human beings and the moon is also very close. Psychiatrists point out that the human body is about 80% liquid, and the gravity of the moon can also act on the liquid in the human body like the ocean tide, forming the "biological climax" and "biological low tide" of the human body. At the full moon, the biological tide is at its peak, and the moon has a strong influence on human behavior. At this time, the potential difference between the head and chest is relatively large, which makes people easily excited, emotionally unstable and prone to accidents. Maurice, a professor at Illinois State University in the United States, even pointed out that human murder, poisoning, depression, heart disease and so on all have a certain relationship with the moon's profit and loss. He thinks that the cations produced by the moon can induce people's abnormal behavior.
