I Just Finished Popularizing Science About The Apocalypse, And The Apocalypse Was Detonated In Advan

Chapter 110: Another civilization exists! [New book is on the shelves, beg for full order, second update]

The so-called far side of the moon refers to the side of the moon that always faces away from the earth and the star!

There are countless connections between the earth, stars and the moon.

During the long-term evolution of the Earth-Moon system, the tidal force between the Earth and the Moon gradually slowed down the Moon's rotation, eventually causing the Moon to be tidally locked by the Earth and the Star. From then on, the Moon always faced the Earth and the Star with the same side, while the Earth and the Star The rotation is also gradually slowing down.

Human scientific research shows that about 1.4 billion years ago, a day on Earth lasted only 18 hours and 40 minutes.

Now, the time it takes for the Earth and the planet to rotate once is 23 hours, 56 minutes and 4 seconds, and it increases by 1/75000 seconds every year.

This difference may seem small, but the cumulative effect over millions of years will be extremely huge.

The rotation of the Earth and the Star gradually slows down because the Earth and the Moon gradually become farther and farther apart, and the gravitational influence of the Moon becomes smaller.

The current revolution period of the moon is increasing at a rate of 0.014 seconds per century, while the average speed of stars moving away from the earth is about 3.83 centimeters per year, and it is still accelerating away!

The earth, star and moon, these two celestial bodies have always been interdependent and interacted with each other. Without the moon, the earth and star would become unsuitable for human survival.

In other words, human civilization will not appear on Earth, but will be another unknown civilization, and there may even be no civilization at all!

It can be said that because of the moon, there is civilization and stability on the earth and stars!

Otherwise, the earth and stars will be reversed by the sun and the moon, the mountains and rivers will be reset, the four seasons will cycle through one day, and the two-level iceberg will not be able to exist for a long time.

The most mysterious place on the moon is the back side of the moon!

In comparison, the far side of the moon is older and is of great value for studying the early history of the moon and the solar system.

Because of the existence of living things, Earth Star has experienced many vicissitudes of life, and has long buried its past deeply.

If humans want to know what happened in the earliest days, and if they want to better understand the solar system and their homeland, they can only conduct relevant research through the detection of the back side of the moon.

"The four-sided pyramid was found in the pit below!"

With the help of Jarvis, Jiang Xuan navigated all the way to the pothole where the four-sided pyramid was found.

Because the back of the moon always faces away from the Earth and the sun, and because extraterrestrial meteorites mainly hit the back of the moon, there is a very big difference between the back of the moon and the front of the moon.

On the far side of the moon, Jiang Xuan and Xiao Jin can even walk and move independently without the help of Iron Man armors.

But not on the far side of the moon.

The cosmic rays, solar rays, temperature, etc. here are all so high that even Xiao Jin, who is as powerful as the Star Devouring Beast, can't handle it. He needs to hide in the Iron Man armor to move freely.

This made Xiao Jin, who was not afraid of the sky or the earth, very unhappy!

He is a ferocious beast in the universe, able to travel and fly alone in the universe!

But now I can't bear it, the various rays and high temperature on the back of the moon

"Roar!!!"

Xiaojin roared in frustration, almost dismantling the Iron Man suit!

"Okay, don't be depressed. Xiao Jin, you are still in your infancy now. When you become an adult, these rays will definitely not be able to harm you anymore!"

Jiang Xuan comforted.

In fact, although Xiao Jin is very powerful, he is actually just a child who was only a few days old.

The reason why he is strong is because the genes of the Star Swallowing Beast are strong enough!

"Ouch!"

Xiao Jin was still a little depressed, but he didn’t continue to dismantle the Iron Man suit!

In this way, Jiang Xuan and Xiao Jin dived all the way down to a depth of nearly 100,000 meters. Jiang Xuan and Xiao Jin finally reached their destination!

You know, the diameter of the moon is only 3.476 million meters. Jiang Xuan and the others have dived to one-tenth of the moon's radius at this time!

"How come this cave is so deep?!"

Jiang Xuan frowned.

This cave is a bit ridiculously deep, I don’t think it was formed naturally!

The deepest Yarlung Zangbo Grand Canyon on Earth is only 6,000 meters deep, and its average depth is only 2,268 meters.

Nothing compares to this cave.

Even the Kola Super Deep Borehole, the deepest on Earth, is only 12,263 meters, which is also incomparable to this cave!

The most important thing is that the diameter of the earth, 12.742 million meters, is dozens of times the diameter of the moon.

But there has never been a 100,000-meter deep pit on Earth!

The moon and the earth can be said to have the same origin. Although there are certain differences, they have many commonalities...

Obviously, this deep crater on the moon is very strange, and there is a very high probability that it is not a natural formation!

"Jarvis, when was this deep pit formed?"

Jiang Xuan frowned and asked, "Why do you think there is something wrong with this pit?"

"From the analysis of the rocks in this deep pit, this deep pit should have existed three billion years ago!"

After waiting for a moment, Jarvis responded.

"Three billion years ago?!"

"Could it be that some kind of civilization really existed three billion years ago and landed on the moon?!"

Jiang Xuan looked solemn.

If some kind of civilization came to the moon three billion years ago, why is the Earth still at its current level of civilization?!

Or even become a "super large laboratory" for an alien civilization empire?

In other words, three billion years ago, the Earth was already a "super large laboratory" for an alien civilization empire?!

This idea is so crazy. What kind of experiment needs to be done for three billion years?!

Even the alien civilization empire should have fallen or changed after three billion years!

What is it that makes them, even if civilization changes, do this experiment that lasts for three billion years?!

"The master has arrived. The four-sided pyramid was found at this 4.8 location!"

Jarvis's voice remembered that Jiang Xuan and the others had finally arrived at their destination.

At this time, the depth from the moon’s surface is 110,640 meters!

"Xiao Jin, have you noticed anything different here?"

Jiang Xuan asked Xiaojin while looking around.

For all kinds of energy-related things, Xiaojin's intuition is sometimes more accurate than the detector!

"It's very depressing and scary here. I don't want to stay here any longer!"

Xiao Jin's face was solemn, and he kept looking around, very alert, and even his golden hair stood on end, as if he was guarding against something, an extremely terrifying existence!

"What existence makes the Star Devouring Beast so nervous?!"

Jiang Xuan was a little surprised. This was the first time he saw Xiao Jin showing such vigilance.
