The moon is the only satellite on earth. In many people’s cognition, the role of the moon is only to add a beautiful scenery to the earth at night, and bring some light to the dark night, guiding people walking at night.
However, as human beings enter the era of science and technology and have more knowledge of the universe, we realize that the moon is not only a tool for night lighting, but also a very important celestial body for the earth and human beings. Without the moon, the earth might not have the current ecosystem, and there would not have been the birth and continuation of life.
Some people may not understand that the moon is just a satellite. Is it so important to the earth and human beings? In fact, it’s not how important a satellite is to the earth. The key is that the moon is too special. What’s special about it is that it’s too big. As we all know, it’s normal for planets to have satellites around them. Almost every planet has at least one satellite. Gas giant planets like Jupiter and Saturn have tens of satellites around them.
If it is a small mass satellite, such as Jupiter and Saturn, one or more of them are missing, the impact on the planet is very small. But the moon is a different satellite. Its mass is too big. If its mass is too natural, gravity will not be small. Among the planetary satellites that scientists have observed, the mass ratio of them to the planet is basically more than 1000 times, while the mass of the moon is 81 times that of the earth.
This mass is far from what a satellite should have. If the mass of the moon is only one thousandth of that of other planets, the impact of the moon on the earth will be very small. But the reality is that the mass of the moon is too large, and the gravitational impact on the earth is also very large.
According to the research of scientists, the moon originated from a celestial body collision in the early days of the earth. A Mars sized planet hit the earth, and the debris produced by the collision finally condensed to form the present moon. Therefore, the moon may have been with the earth for more than 4 billion years. In such a long time, the moon has played an important role in the formation of the earth’s ecology.
Therefore, the moon is responsible for a large part of the stable and perfect ecosystem of the earth. The moon earth has formed an integral whole. A large part of the flow of liquid matter inside the earth is affected by the tidal force of the moon. The stable and perfect ecosystem of the earth is closely related to the material flow inside the earth.
Only a perfect ecosystem can provide a hotbed for the birth of life, and let life on earth evolve continuously until the birth of human beings. Therefore, the earth’s life, including the survival and continuation of human beings, cannot do without the moon. Once there is no moon, the earth may usher in huge ecological upheaval. At that time, the earth’s ecological structure will usher in violent plate movement in order to adjust and adapt, and a new round of mass extinction will be staged.
At this time, I believe many friends have understood the importance of the moon to the earth and human beings. We can’t do without the moon. I hope it can always be around the earth. However, the ideal is beautiful, and the reality is often very cruel. According to a large number of observations and studies by scientists, the moon is moving away from the earth step by step.
Through a large number of observations, scientists have found that the moon’s distance from the earth may have started a long time ago, with an average distance of about 3.78 cm per year. Although this range is very, very small, but as long as the time is long enough, one day, the moon will leave us. From the beginning, the moon was more than 100000 kilometers away from the earth, and now it is 380000 kilometers away.
Why does the moon keep moving away from the earth? In fact, the reason behind it is that the mass of the moon is too large. If the mass is too large, the gravitational interaction between the earth and the moon will continue to seek a balance. Although the moon always revolves around the earth, because of its very large mass, it will also produce a greater repulsive force, which keeps the moon away from the earth.
In fact, this situation is also very normal, you should know that the mass of the larger object is not willing to become a satellite of the planet, unless the mass of the planet is far more than that of the object. The mass of the satellites of other planets is more than 1000 times that of the satellites. This huge mass difference makes the satellites dare not have the slightest idea to escape. The strength gap is too big.
However, the mass of the moon is only one 81th of that of the earth. This mass ratio is not a very big gap between celestial bodies. Therefore, it is very difficult for the earth to completely bind the moon. The moon does not look down on the earth and will not willingly revolve around the earth. In the eyes of the moon, the mass of the earth is not big enough. If the earth is replaced by Jupiter, the moon naturally will not have the slightest idea of escape, because the power gap is too big to allow.
The moon is a little far away from the earth. One day, it will leave the earth and become a free body. Once the earth loses the moon, great disasters may come. What will human beings do at that time? Some people may think that human beings are also facing a huge disaster. If not, they will end up in the mass extinction just like the dinosaurs 65 million years ago.
Is that really the case? In fact, we all think that it will take a long time for the moon to completely break away from the earth’s gravity. As early as billions of years ago, the moon was a little bit far away from the earth, but it could not completely leave the earth. Even if it leaves the earth one day in the future, at that time, human civilization may have already become a powerful interstellar civilization.
The strength of science and technology is endless. As long as human beings become a powerful interstellar civilization, is this the problem of the moon? Of course not. At that time, even if the moon was gone, we could also rely on the spacecraft to pull a celestial body of the same mass to make up for the position of the moon, so that it could continue to form a stable gravitational balance with the earth, and continue to stabilize the earth’s ecological structure.
This is the power of science and technology. As long as the power of science and technology is strong enough, no disaster will threaten the survival of the earth and mankind. It is possible that in the future, when human civilization is strong to a certain extent, we will transform the earth in all aspects to make it a wandering planet. At that time, we will leave the solar system with the earth and explore the vast universe.
