Preface
The Moon is a very important part of the history of human space exploration, and it is regarded by mankind as a second earth that can be used by humans to live, work and store resources. But over time, the question is asked: Is the moon a star or a death star?
The closest celestial body
On the earth where humans live, apart from the sun, the closest celestial body is the moon. The new moon hanging in the night sky makes people yearn for it, and the full moon hanging in the sky is even more unforgettable.
But what is surprising is that despite its proximity, so far people have very little understanding of the moon.
It is known that the moon is a satellite that orbits the earth, and it weaves a beautiful and spectacular scene hand in hand with the earth. 384.4 million years ago, the moon was very close to the earth and the moon phases changed dramatically, but over time, the moon gradually moved away from the earth, and the moon phases changed more and more slowly.
It can be said that the state of motion of the Earth-Moon system is a natural process, and it also makes people doubt its past and present lives.
Although it is very close to the daily life of human beings, people's understanding of the moon can still be described as "strange".
Grow up, grow old, and die.
The moon also had a youthful appearance, about 4.5 billion years ago, when the earth and the moon were combined. Scientists believe that there was a dense atmosphere over the moon at that time, which also proves to some extent that there were volcanic eruptions on the moon.
This is because when the surface of a celestial body is finally free to release energy, it will choose to form a volcano on the surface, and on the early moon, in addition to volcanoes, there were many craters piled up on it.
Later, the massive amount of energy released from the moon washed away all the atmospheric components of the atmosphere, and when this period ended, the moon began to enter old age.
During the "prime" and "old age" periods, the core of the celestial body begins to gradually cool, which means that there will be no new changes in the celestial body.
The Moon is now in a "Death Star" phase where it is unable to produce new changes, specifically, the Moon will no longer form new craters, no volcanoes erupt again, and its gravity and gravity will remain fixed.
Although the Moon has turned into a "death star", it has to be admitted that it is still cruising around the Earth.
Physicists can give a relatively simple and clear explanation for this, and the movement of the moon also has its own physical laws.
In a celestial system, as long as two celestial bodies are attracted to each other, they can form the basis of motion.
In the case of the Earth and the Moon, the gravitational pull between them can cause the Moon to move around the Earth and even lengthen the time on the Moon.
And the friction between them can make the moon's rotation slowly turn into an revolution around the earth, all as a result of the mutual attraction between the earth and the moon.
Although the moon has lost its vitality, its place in people's hearts is irreplaceable.
A phenomenon that cannot be explained independently.
In the process of exploring the moon, people are not only amazed by the death of its life, but more importantly, it can help people solve many astronomical phenomena that cannot be explained independently.
In the 17th century, he used a telescope to observe the moon and concluded that the "tidal force" exists, that is, the attraction of the moon affects the tides, causing the tidal range to change constantly.
Later, in the 18th century, astronomers confirmed the authenticity of the two physical concepts of "conservation of angular momentum" and "gravity", which provided an important reference for people to understand the mechanism of action of the Earth-Moon system.
Without the moon, the earth's tidal phenomena would be monolithic and simple, which also provides a scientific explanation for the mythical "full moon and round man".
To this day, people continue to explore the mysteries of the universe with great enthusiasm.
Why do countries want to explore the moon?
People are keen to explore the mysteries of the universe, and the attraction to all this finally led to the first humans landing on the moon.
At that time, the moment when the astronauts stepped on the moon was recorded in history, and the moon landing became the first climax of human exploration of the universe.
Later, not only human beings, but also unmanned probes continued to go to the moon, and they transmitted information about the moon's resources, geology and other aspects back to the earth, further improving people's understanding of the moon.
Although the Moon is a "death star", it still has its own unique charm that attracts mankind to continue to explore.
To put it another way, although the Moon does not have an atmosphere cover, it can still provide places for humans to continue exploring the unknown.
Its gravity is smaller than that of Earth, volcanoes and craters continue to show astronauts the trajectory of its years, and staying on the moon for a long time can also form a new test for life and species on Earth.
Of course, with the gradual maturity of technology, more experimental facilities can also be "planted" on the moon, which is also very important for the process of human exploration of the universe.
Thinking about it from another angle, although the moon does not have a natural environment like the earth, it still has a unique resource charm to attract human beings.
Under its "shelter", scientists can explore the production of more rare resources, re-analyze and reuse various resources on the earth's surface.
Taking solar energy as an example, although there is solar radiation on the earth, only a small part of the solar energy reaches the surface due to the obstruction of the atmosphere.
The Moon is not blocked by an atmosphere, which also causes the Moon to emit much more solar radiation than on Earth.
If human beings can fully utilize this part of the solar energy resources, it will become a paradise of clean energy.
In addition to solar energy resources, the moon is also rich in helium resources, etc., and scientists can make more resources according to their properties, so as to reduce excessive dependence on the earth.
Of course, in addition to the two advantages of the birth of resources and solar energy, mankind also has a more long-term goal, hoping to successfully realize the "moon base", further deduce and adapt the mysteries of the universe, and finally realize complete self-sufficiency of human beings in space.
More importantly, the lunar base can avoid natural disasters on the earth's surface, making it safer and more stable.
In the future, mankind will realize the "Moon Project"
Just as people use the earth's resources, human beings also want to be able to fully enjoy and utilize the resources of the universe.
Today, with the continuous progress of science and technology, people can foresee the smooth implementation of the "Moon Plan".
In an era of continuous progress in science and technology, mankind always wants to be able to explore more unknown areas.
In this technological space industry, various objects and theories of the universe are studied very thoroughly.
For example, the moon is a celestial body, which is very close to the earth, and can provide the earth with various information and resources to a certain extent, and rely on it to expand human scientific knowledge and civilization technology.
Nowadays, the technological society is becoming more and more developed, and there are many airborne vehicles that can be seen everywhere in space.
The moon has been studied and monitored, and many experts have made corresponding predictions about the moon's lifespan.
In the future, the moon will be used as a provider of natural resources, a base for humanity to conquer the universe.
In the technological society, people's exploration of the universe is also gradually deepening.
Many people compare different alien planets to the Moon, but they don't know that they have long since become a "death star".
