"Don't worry, wait a little longer!"

Chen Lang shook his head, then looked to his side.

Because it was a busy period, only Liu Yishou, Zhao Tingyun and Zhao Kai came to the scene with Chen Lang.

The simulated ones were also the four of them.

Looking at Zhao Tingyun, Chen Lang couldn't help but said, "How is it? This can be regarded as realizing your idea of ​​landing on the moon yourself?"

Zhao Tingyun was speechless, then nodded.

Although I knew it was fake, it was no different from landing on the moon in person, and it was much safer.

Chen Lang looked at Zhao Kai again at this time, and said, "Although you didn't go to the moon, you will be in charge of your people throughout the whole process. Let me say a few precautions first."

"Yes!"

Zhao Kai nodded.

"First!"

With a wave of Chen Lang's hand, the projection of the moon appeared in front of everyone.

Pointing to the moon, Chen Lang said: "There are dark parts and bright areas on the surface of the moon. The bright areas are highlands, and the dark areas are low-lying areas such as plains or basins, which are called lunar land and lunar maria respectively.

Of course, there is no water on the moon. The so-called maria actually has no water at all.

The reason why it is called the lunar sea is because early astronomers thought that the dark areas were covered with sea water when observing the moon, so they called it the sea.

The more famous ones are the sea of ​​clouds, the sea of ​​dampness, the sea of ​​tranquility, and so on.

These bright places are mountains, but our goal is not mountains, nor the lunar sea. "

As he spoke, Chen Lang rotated the projected moon, pointed to the back of the moon, and said, "Here is our goal."

The crowd watched intently.

It was a mess full of potholes and weird mountains.

And as Chen Lang continued to zoom in on the virtual projection, finally, the surface of Chen Lang's finger appeared clearly in front of everyone.

"What is this stuff?"

Liu Yishou looked at the inexplicably familiar boulders and pyramids in front of him, and he was stunned.

The same goes for the people next to them.

Why are there pyramids on the moon?

Or, this is not a pyramid, but a stone that looks very similar to a pyramid?

"Prehistoric ruins!"

Chen Lang spoke lightly.

"Our goal is to excavate prehistoric ruins?"

The ten astronauts were also stunned.

Chen Lang nodded again, and continued: "There is day and night on the moon, and the moon's rotation period is 2732 days.

But the earth revolves around the sun, and the moon revolves around the earth. Although the rotation period is 2732 days, because of the lag, a day and night on the moon is 2953 days, which is about one month in the lunar calendar.

And since the moon can rotate, why does it have a back side?

According to modern astronomical science, the so-called back side of the moon is due to the tidal locking between the earth and the moon, so only one side of the moon always faces the earth.

The side we will never see from Earth is the far side of the Moon.

The back and front of the moon are completely different in terms of terrain.

However, this is not the main reason. "

Chen Lang looked at the crowd and said, "The earth also revolves around the sun, why doesn't the earth have a back side? Why does the moon have one?

The gravitational force from the earth is only one aspect. If it is only the gravitational force from the earth, it does not have such a back side.

The real reason is because of the core of the earth! "

Chen Lang waved his hand, and the line-by-line comparative information appeared in front of everyone.

"The front side of the moon is relatively flat, like the surface of a normal barren planet.

On the other hand, the back is rugged, full of bumpy impact craters, whether it is material composition, morphology or rock age, the back is very different from the front.

This is not the most important thing, the most important thing is underground.

The front side of the moon is flat, facing us, the thickness of the moon's shell is only about 60 kilometers.

But on the back of the moon, the thickness of the moon's shell is about 150 kilometers.

what does this mean?

It means that the core of the moon is biased toward the front, so the front of the moon has been attracted by the gravity of the earth, and humans have been unable to observe the back of the moon from the earth.

However, for a planet, there is no doubt that the core of the earth continuously attracts the outside matter at the beginning, and finally forms the core of the planet.

And since it is the core, why is it not at the center of the moon, but on the side closer to the earth?

Because, the moon was made! "

"how can that be?"

Xu Zifeng looked at Chen Lang with his mouth wide open, his face full of disbelief.

After Chen Lang said this kind of statement that overturned common sense, Liu Yishou and others were at most surprised and shocked, but no matter how their emotions fluctuated, they would never doubt what Chen Lang said.

In the past, Chen Lang used too many facts to tell them that Chen Lang would never tease them.

Especially when it comes to business.

But Xu Zifeng was different. It was the first time for her to have close contact with Chen Lang. Although it was only a projection, she still felt that after Chen Lang spoke, her common sense and cognition were all overturned.

Therefore, she instinctively doubted and instinctively couldn't believe it.

"Why not?"
