There is a title that has become a habit that many people are accustomed to, and that is the immature "Sun Father" and "Moon Mother".
In many people's minds, the moon is a quiet and virtuous woman, and the sunny sun is the moon's older brother.
But in this title, the moon seems to have become a creature on earth, and she can be called "mother-in-law", and the moon also has a masculine "sun brother".
But in reality, the sun and the moon are both huge stars in the sky, and there is no relationship between the two, and there are many stories behind the fact that humans call the sun and the moon "brother" and "mother-in-law".
How did this habit come into being?
And what is the profound meaning of human beings describing the moon as a "mother-in-law"?
What is the significance of the Moon to the Earth?
How did humans explore the mystery of the formation of the moon, and with the development of science and technology, humans began to try to create an artificial moon?
But why did this artificial moon never come to rest?
1. The importance of the sun and moon to the earth.
The sun and the moon are both the brightest sources of light on the planet and the greatest "umbrella" on the planet.
The sun is the "mother" of the earth, not only the "nutrient soil" of the earth's creatures, but also the "seed" that allows all things to grow on the earth.
Everything on the earth is inseparable from the light of the sun, and the heat of the sun also provides the required temperature for everything on the earth, and protects everything on the earth in the embrace of the sun.
And the moon is the most beautiful "sister" on earth, and at night, she will radiate a warm light, illuminating everything on earth.
There are many animals and plants that grow and thrive under the illumination of the moon, and in the hearts of human beings, the moon is a symbol of love, and people often compare the moon to a gentle woman, which is also the reason why the gentle and pure image of the moon has gradually taken root in people's hearts.
However, although the sun and the moon are far away from the earth, they are closely related to the earth, and some people even say that the earth is like a child of the sun, and the moon is the "sister-in-law" of the earth.
However, some people compare the relationship between the earth, the sun and the moon to a "mother-daughter" relationship, that is, the sun is the "mother", the moon is the "mother's daughter", and the earth is the "mother's son".
Who is the "child", "son", and "daughter" of whom, and the relationship between the earth, the sun, and the moon, has been the subject of endless debate among various scholars.
Either way, the sun and moon are vital to the earth, as they not only provide light and energy to everything on earth, but also protect against some of the cosmic rays.
In addition, the atmosphere of the earth is also formed under the condition of the right temperature on the earth under the irradiation of the sun, thus providing a suitable growth environment for the creatures on the earth.
The moon is the "umbrella" of the earth, and the gravitational pull of the moon can help the earth rotate slowly on the one hand, thus providing a good living environment for the creatures on the earth.
On the other hand, the Moon can also block some cosmic rays and protect life on Earth, while the Moon can also provide light to the plants and animals on Earth.
At the same time, the moon can also help organisms on earth regulate their biological cycles, preventing animals and plants from being damaged by excessive sunlight.
2. The mystery of the formation of the moon.
The Moon is the largest satellite on Earth and the closest star to Earth, and it is also the first step in human exploration of space.
But how did the moon form?
In the process of human exploration of the moon, scientists have also begun to explore the mystery of the formation of the moon.
It was not until the beginning of the 20th century that American scientists began to study that there were many craters scattered on the surface of the moon, and that the surface soil on the moon was also formed by meteorite impacts.
And the surface rocks on the moon can be traced back to 4.5 billion years ago, and the formation time of the crustal rocks on the moon can also be traced back to 3.8 billion years ago, and the age of this moon is even older than the age of the earth.
At the beginning of the formation of the moon, the rocks on the surface of the moon were formed by volcanic eruptions, and the formation time of these volcanic rocks can be traced back to 4 billion years.
So when was the formation of this moon?
In the process of human exploration of the moon, scientists have put forward many different theories, but they can basically be divided into three major factions, one is the Thermidorian school, which believes that the moon is due to the rotation of the earth to produce satellites from a part of the molten material on the earth, which is the moon.
The second is the Cold Moon School, which believes that the Moon is caused by a planetary body on the Earth hitting the Earth, thus crashing out of the Moon, and the Moon is therefore called an impact satellite.
The third is homology, which believes that the moon and the earth are homologous moons, and that they are the same as the earth, because in the process of the rotation of the sun, the matter between them gathers and eventually forms stars.
3. Make an artificial moon.
Since the first satellite of mankind in the 20th century rushed out of the earth and into space, in the 60s of the subsequent 20th century, human beings set foot on the land of the moon to explore the closest star to the earth in the solar system - the moon, and 50 years later, human beings began to try to create an artificial moon.
The manufacturing process of an artificial moon has already begun in the United States, and the artificial moon will be placed in orbit 32,000 kilometers from the Earth, and the artificial moon will have a larger radius than the moon, and the artificial moon will be 10 times brighter than the moon, and will also be able to provide light for the night on Earth.
The artificial moon will be composed of dumbbell-shaped shiny objects and a large area of film, when the sun shines on the artificial moon, these large areas of film will shine the sun's rays onto the ground, providing light to the ground.
And when night falls, these dumbbell-shaped bright objects reflect the sun's rays from the earth directly onto the ground, thus providing illumination for the earth.
The artificial moon will be jointly explored by the United States and Russia, and this artificial moon will be placed in areas of the earth where human activities are concentrated, such as some large cities, and when night falls, this artificial moon will be able to provide light to the earth, thus facilitating nocturnal activities on the earth.
The artificial moon will also be able to illuminate some remote areas of the earth, as well as some places where there is no light, and will also be able to provide light for the plants on the earth.
The artificial moon will be placed in an orbit 32,000 kilometers above the Earth, called the Lagrangian point, which is very far from the Earth, so it will not affect the exploration of the artificial moon.
The artificial moon that people see at night will be brighter than the real moon, and it will be larger than the moon, but during the day, people will not be able to see the artificial moon, and it will not affect their life during the day.
And this artificial moon will be brighter than the moon, but it will not replace the sun, nor can it replace the moon, and the functions between them are completely different.
Fourth, the artificial moon is gone.
Although the artificial moon has been hyped in the media, in the years that followed, there was no follow-up of the artificial moon, and there was no news about the launch plan of the artificial moon.
Although the artificial moon manufacturing plan has attracted many people's attention, due to many technical difficulties in the launch of this artificial moon, the launch plan of this artificial moon has been shelved.
One is the issue of speed during the launch of this artificial moon, which has to surpass not only the moon but also the earth, so the launch speed of this artificial moon needs to be accelerated to 11.2 km/s.
However, the current launch technology on Earth is not yet able to do this, and even satellites can only launch at 8 km/s, and this artificial moon can launch twice as fast as satellites.
During the launch, another question is involved, that is, whether the artificial moon will collide with the moon during the flight, so the flight trajectory of the artificial moon will be adjusted to an orbit that will not collide with the moon.
And there is another question involved in the launch of this artificial moon, that is, how much can this artificial moon irradiate, and how long.
In addition to illuminating the earth, this artificial moon can also illuminate some remote areas of the earth and some ships in the ocean, so as to facilitate people's night activities, but the launch and operation of this artificial moon require huge costs.
Technically human beings are not able to do this, so the launch of this artificial moon has been shelved, and in practice, the artificial moon does not have such a large range of light on Earth, which also causes the problem of light pollution.
On the other hand, the extent of the artificial moon will produce light pollution, which will adversely affect the plants and animals on the earth, and will also affect the ecological balance of the earth.
In real life, human beings do not need this artificial moon, so there is another question involved in the manufacture and launch of this artificial moon, that is, the actual needs of this artificial moon, and whether this artificial moon is necessary to be manufactured.
V. Conclusion
Humans have been exploring space for decades, and in the process of exploring in space, many ideas and hypotheses about the formation of the moon have been born.
These hypotheses reflect not only the exploration of the moon, but also the search and curiosity of mankind about the origin of the universe.
But on the other hand, human beings should also respect the laws of nature and should not interfere excessively with the laws of the universe.
However, it also reminds us to carefully consider the impact of technological development and the actual needs of the earth, and at the same time to respect the laws of nature and not to interfere too much with the laws of the universe.
The moon is not only a satellite of the earth, but also a "protective umbrella" on the earth, and human beings should cherish and explore this planet more.
At the same time, as an important symbol and symbol in human culture, the moon plays an important role in human history and culture, which deserves more in-depth excavation and research.
