Chapter 430 The Moon Was Made (Subscribe)

"Let's go, let's experience the moon too!"

In the Galaxy War and Defense Center, Chen Lang led the crowd to the simulation room.

After entering the simulation room, Chen Lang asked, "Qiuqiu, start the simulator."

"Yes!"

The sound of the ball sounded.

Afterwards, the originally dim simulation room, the light changed rapidly, and became the interior scene of the No. 1 Starship Battleship at a very fast speed.

This is a virtual projection system.

Chen Lang and others stood in the virtual room, as if they were standing inside the galaxy battleship.

At this time, in the middle area between the moon and the earth, inside the flying No. 1 Star River battleship, several small simulators slowly flew up.

The ten astronauts in the Starship Battleship No. 1 gathered quickly, but Xu Zifeng was a little overwhelmed.

After standing in a row, Xu Zifeng stared dumbfounded as several instruments she could not understand projected the figures of Chen Lang, Liu Yishou and others in the air.

"Commander-in-chief!"

With a swipe, the ten astronauts saluted in unison.

Chen Lang nodded slightly, and beside Chen Lang, Liu Yishou and others looked down at their hands in amazement.

Just like the real thing.

This is virtual projection.

People are on earth, but because they are in the simulation room, the scene inside the battleship is completely simulated, so they even feel like they are in the battleship.

In the battleship, the ten astronauts were also a little confused. Although they had been psychologically prepared, it was still incredible to see several living people appearing in front of them.

That's the beauty of technology.

fake?

Only Xu Zifeng, after staring at all this in a stunned manner, she couldn't help but stepped forward and reached out to Chen Lang.

However, when the hand crossed, it was passed through.

Yes!

fake.

is a virtual projection.

Those small simulators are specially made for simulating projection.

"Have you touched enough?"

Chen Lang raised his brows and asked Xu Zifeng.

It's really awkward.

When Xu Zifeng touched Chen Lang in the battleship, he passed through it, and what he touched was completely air.

In the simulation room on Earth, Xu Zifeng in front of Chen Lang was projected. She touched Chen Lang and passed through it.

However, it was not Chen Lang's body that passed through, but Chen Lang's body passing through her arm.

In her eyes, Chen Lang was fake and projected.

In Chen Lang's eyes, she was fake and projected.

"Hey hey hey!"

Xu Zifeng was a little embarrassed.

"Can I live stream?" Xu Zifeng asked.

"Don't worry, just wait a while!"

Chen Lang shook his head, then looked beside him.

Because it was a busy period, only Liu Yishou, Zhao Tingyun and Zhao Kai were present with Chen Lang.

It was also the four of them who were simulated.

Looking at Zhao Tingyun, Chen Lang couldn't help but say, "How is it? This is considered to be the realization of your idea of ​​landing on the moon yourself, right?"

Zhao Tingyun was speechless, then nodded.

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

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

"Yes!"

Zhao Kai nodded.

"First!"

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

Reaching out 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 depressions such as plains or basins, which are called lunar land and lunar sea respectively.

Of course, the moon has no water. The so-called moon sea actually has no water at all.

The reason why it is called the Moon Sea is because the early astronomers thought that the darkened areas were covered by sea water when observing the moon, so they called it the sea.

The more famous ones are the Sea of ​​Clouds, the Sea of ​​Wet, the Sea of ​​Tranquility, and so on.

These bright places are mountains, but our goal is not mountains, nor moon seas. "

Speaking, Chen Lang rotated the projected moon, pointed to the back of the moon, and said, "This is our goal."

The crowd watched intently.

It was a mess of potholes and weird mountains.

And as Chen Lang kept zooming in on the virtual projection, finally, the surface of Chen Lang's finger finally 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 the whole person was stunned.

The same goes for the few people around.

The moon, why is there a pyramid?

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

"Prehistoric ruins!"

Chen Lang spoke lightly.

"Our goal is to excavate prehistoric ruins?"

The ten astronauts were all stunned.

Chen Lang nodded again and continued: "There are days and nights on the moon, and the moon's rotation period is 27.32 days.

But the earth revolves around the sun, and the moon revolves around the earth. Although the rotation period is 27.32 days, but because of the lag, one day and night on the moon is 29.53 days, which is about a month in the lunar calendar.

And since the moon rotates, why does he have a backside?

In modern astronomical science, the so-called back of the moon means that due to the tidal locking between the earth and the moon, the moon will always have only one side facing the earth.

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

The topography of the back and front of the moon is completely different.

However, this is not the main reason. "

Chen Lang looked at everyone and said, "The earth also revolves around the sun, why doesn't the earth have a backside? But the moon does?

The gravitational force from the earth is only one aspect. If it only comes from the gravitational force of the earth, it does not have such a backside.

The real reason is because of the Earth's core! "

As Chen Lang waved his hand, line by line comparison data appeared in front of everyone.

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

On the back, there are bumpy, bumpy impact craters, and the back is very different from the front in terms of material composition, topography, and rock age.

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

On the front side of the moon, that is, the flat side facing us, the thickness of the lunar crust is only about 60 kilometers.

But on the far side of the moon, the thickness of the lunar crust is about 150 kilometers.

what does that mean?

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

However, for a planet, the core of the earth is undoubtedly attracting foreign matter at the beginning, and finally forms the core of the planet.

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

Because the moon was made! "
