When people look at the stars at night, they will always find a bright moon in the sky.
Under normal circumstances, the moon observed by people is not only round, it will appear different shapes according to different time. For example, at the beginning of each month, the moon seen by people is the shape of a crescent moon. By the middle of each month, the moon will gradually become rounder. For this reason, the ancients called these phenomena "new moon" and "moon look".
Although in the eyes of ordinary people, the moon is a very ordinary celestial body, as long as the sky is clear at night, people will look up and see the bright moon. In order to praise the moon, the ancients wrote many classic poems about the moon. However, in fact, the moon is a very mysterious celestial body. Not only are there many legends that occur on the moon, but there are countless unsolved mysteries about the moon.
When did the moon appear and why is it mysterious and mysterious
In ancient times, due to underdeveloped transportation and technology, the ancients were fascinated by the moon. They believed that there was an Guanghan Palace above the moon, and the beautiful Chang'e was inhabited.
In addition, in ancient myths, there is also a legend of " Pangu to turn into the sun and the moon". According to legend, after Pangu's death, his left eye turned into the sun and his right eye turned into the moon. These legends are indeed enough to prove the mystery of the moon.
However, such a mysterious and beautiful moon has a more mysterious life experience. Because in ancient legends from different countries around the world, it is generally believed that there was no moon in the sky at the earliest, and the moon is actually a acquired celestial body.
Regardless of whether these legends are true or not, the mystery of the moon has always triggered the exploration of people on earth.
What is surprising is that the moon is not only mysterious, but also affects the earth at all times. For example, when the moon orbits the earth in the sky, the earth's crust will have subtle ups and downs. Of course, these ups and downs are not as profound as earthquakes, but are so subtle that it is impossible for the naked eye to notice.
However, when this change is placed on sea level, you will find that whenever the moon rises, the sea water will fluctuate to varying degrees. This is what people often say about tides.
Secondly, I wonder if you have noticed that the moon always faces the earth. Even if it circles around the earth for many times, people can see only one side of the moon.
This makes people feel very confused, because when other satellites surround the main planet, they always rotate continuously, so different surfaces of these satellites can be captured by the main planet, but only the moon always reveals a fixed side from beginning to end. Even scientists can't explain this phenomenon clearly.
In addition, there is another incredible thing that is that there was no moon above the earth a long time ago. This is not only confirmed in the scientific community, but also recorded in ancient mythology. It is hard to imagine that people in the past actually discovered all this.
In the Manchu mythology in southern Africa, the phenomenon of "there was no moon in the sky before". In addition, it is also mentioned in the " Mountains and Seas" that before the great flood in the end of the world, there was only the sun and no moon in the sky.
That is to say, the moon appears after the flood. However, even if all this is true, no one knows where the moon comes from and what kind of material it is made of.
Scientists have discovered that the moon flies 4 cm from the earth every year and will sooner or later leave the earth
In addition, when scientists studied ancient coral fossils tens of millions of years ago, they accidentally discovered that 37 million years ago, when the earth did not have the moon satellite, there were about 400 days on the earth every year, with at least 30 hours a day, which is not as accurate as 365 days now. However, just after the moon formed the Earth's guardian satellite, the number of days on Earth began to gradually shorten, and the 365 days were gradually formed.
This amazing discovery scared scientists. They speculated that if the moon had been orbiting the earth, whether it would mean that the time on the earth would become shorter and shorter in the future, and it might even be that the number of days per year would be reduced to 300 days, and every day of human beings would be greatly shorter than 20 hours.
But this is just a speculation, because the moon happens to exist, the earth has been operating very smoothly for tens of millions of years. Moreover, the moon's tide-induced force always affects the changes in the earth's crust at all times, and prevents large vibrations from occurring inside the earth at all times. It can be said that the appearance of the moon is like a nanny, protecting the earth's surroundings.
In addition, when the moon orbits the earth, it also uses its body to block the rampage of many meteorites . The Crater that people can see now is the trauma left by those meteorites hit the moon.
It can be imagined that if there was no moon, volcanic eruptions and earthquakes inside the earth would be more irregular, and the earth would be more likely to be impacted by foreign meteorites. At that time, life on the earth would usher in catastrophes again and again.
Recently, scientists discovered another amazing fact that the moon gradually flew away from the earth at a speed of 4 cm per year. This amazing fact has to remind people of a legend that in ancient times, people could communicate with each other between the human world and the divine world. Human beings lived on the earth, while gods lived on the moon. There was a tower of heaven connected between the two worlds.
But one day human greed angered the gods, so the Tower of Tongtian suddenly broke in a war between the two realms. Since then, the God Realm and the Human Realm have completely parted ways, and the two realms have seen no bond that can be connected from now on.
When the moon lost its connection, it could only float in the air. Later, it ran farther and farther, forming the moon that people see now. So over the years, many people believe that the moon must be inhabited by gods and higher wisdom.
Although this legend is magical, according to scientists' speculation, the moon was indeed very close to the ground a long time ago, and it was only 26,000 kilometers.
But now, the moon and the earth are separated by 380,000 kilometers. From this point, we can see that the moon has indeed gradually separated from the earth at a slight distance every year.
If it is calculated at a speed of 4 cm, then in 10 billion years, the distance between the moon and the earth will expand to 780,000 kilometers. Sooner or later, the moon will leave the earth's orbit. Rush into the further space.
Just imagine, if such a day really comes, when the earth where humans live without the protection of the moon, the earth may really usher in a completely wandering time like in the movie.
