The lunar rover Yutu is one of the probes launched by China to explore the moon . According to the information sent by the lunar rover Yutu, people have discovered many mysteries of the moon.

But apart from the mysteries that humans have discovered, what other mysterious places do you know about the moon? Next, I will share some with you.

The first one is the rocks on the moon. As an aside, how many years do you think the moon has existed in the universe? According to official data, the formation of the moon was later than that of the earth.

However, according to NASA's research, the moon rocks they obtained are 3.6 billion years old, 4.3 billion years old, 4.5 billion years old, 4.6 billion years old, etc...

However, according to official reports, the earth was formed 4.6 billion years ago , and the ancient rocks on the moon are actually the same age as the moon. This makes people wonder, how many billion years has the moon existed?

Second , the geological structure of the moon is very different from the geological structure of the earth. The geological structure of the earth can also be explained by the movement of the crust.

However, the surface of the moon is full of craters, and it can even bear the huge impact of meteorites. To use an example, it is the momentum and friction between the pistol and the bullet at the moment when the bullet is fired.

When the bullet hits the target, the target will withstand the pressure brought by the bullet and not fall down. Back to the topic, when the moon is hit by a meteorite, it can only leave a shallow crater on it .

It's just that the craters on the moon are very different from the craters on other planets in other solar systems. The craters on the moon are very shallow and cause little damage to the moon.

If it is replaced by the earth, it will be different, so the moon's geology is very hard. If we don't use probes and let humans land on the moon, what will happen?

human landing on the moon

Humans land on the moon, what will happen? Throughout the history of global human aviation development, humans have successfully landed on the moon in the last century.

Human beings left their footprints on the moon for the first time, but we must understand one thing, that is, the moon does not emit light.

To explain in the language of scientists, the moon is a satellite revolving around the earth, and the principle of the moon's light is that it reflects the sunlight itself.

Of course, some friends around me have raised such a question, why doesn't the moon reflect the light of the earth? I just want to say that the earth is a planet and it doesn't shine....

Back to the topic, once an astronaut has landed on the moon, the first problem he will face is that the moon is all dark and there is no light at all.

Because the moon is a rare and colorless planet , if an astronaut stands on the moon to watch the earth, it is equivalent to the moon we see on the earth, but there will be a strong visual impact.

Although the earth itself does not emit light, and most of the plants and creatures on the earth depend on sunlight, the earth has colors and is a beautiful blue planet in the universe .

But this is what astronauts have to overcome, but in addition to the visual impact, astronauts may be under tremendous psychological and physical pressure.

This can be understood from two aspects. The first is food and water sources, and the second is the time on the moon. Why do you say this?

Because the moon is the natural satellite of the earth, there is no trace of life on the moon at all. If astronauts want to step into the earth, they first need to bring enough water and food, otherwise there may be no return .

Secondly, if the rotation speed of the moon is compared with the rotation speed of the earth, the rotation speed of the moon is relatively faster. The time on the moon is several days faster than that on the earth, and all the biological laws developed on the earth will be broken.

It can be summed up in three words: jet lag. And these are the most basic. According to the astronauts' response, they are standing on the moon and dare not look at the moon at all, so what are they afraid of?

scary things about the moon

Astronauts stand on the moon and dare not turn around to look at the earth. What is so terrible about the earth? People have seven emotions and six desires. Many times what people feel is not happiness, but fear, especially when a person is locked in a dark space.

This is similar to that in space. In the moon, if the astronauts turn around and look back at the earth, they can only see a huge blue sphere, and only one blue sphere can be seen, and nothing else can be seen.

The huge visual impact will cause great psychological pressure on the astronauts, especially the patients with giant phobia, who have difficulty breathing every minute. Why do you say that?

Because the actual volume of the earth is much larger than that of the moon , if you look at the earth from the moon, it is equivalent to looking at the sun from the sky above the earth. All human senses are magnified by at least dozens of times. Who is not afraid of seeing this?

Of course, this is only from the relationship between the earth and the moon. If you look at it from the astronauts themselves, the astronauts may want to go home the moment they land on the moon.

Because the sense of loneliness and emptiness on the moon is unprecedented, and the five senses of human beings are closely related to their environment.

To put it simply, you have entered a university from high school. When you enter a university, you need to adapt to this environment. If you adapt well, you will be familiar with it. If you don’t adapt well, you will only feel boundless loneliness.

And astronauts from the earth to the moon are just an enlarged version of the migration. After landing on the moon, there will be a sense of loneliness in life, like being abandoned by the world.

However, some netizens put forward another view, that is, will there be some kind of special sound in space that makes astronauts feel scared?

In fact, no, in space, humans cannot hear any sound. Friends who have studied physics know that sound transmission requires a medium, that is, it needs the assistance of air.

However, space is a vacuum, so astronauts basically cannot hear sound in space, and astronauts can survive in space entirely because they carry some special transmission equipment.

At present, human exploration of the earth is still a long way off. What do you think about this? Six small questions, when do you think humans will be able to popularize space travel?
