The Three-Body Problem: The Most Competent Wallfacer of All Time

Chapter 48
Jiang Yu didn't hide his surprise: "What's going on?"

"Under the gravitational pull of the three stars, this planet 'lay down'." Yang Dong explained:

"I have to admit that this is a very strange phenomenon, but it is not impossible. Uranus in the solar system is revolving 'lying down', looking like a 'lazy man'.

"Uranus probably 'laid down' long ago, at a conjunction with Jupiter.

"And in this galaxy with three stars, the phenomenon is not difficult to understand.

"It should be that the trisolaran star is subjected to the gravitational force of the three stars from different directions, and the trisolaran star is 'turned down' by chance.

"Since then, Trisolaran's autobiography has been as usual, but its 'butt' has been facing the sun, but its 'head' has not seen the sun for decades. This scene is like someone rolling on the ground."

Jiang Yu was a little surprised: "Isn't it because of the influence of the stellar tidal force?"

"No," Yang Dong said affirmatively, "If only one side of the planet faces the sun because of tidal forces, there wouldn't be this 'dawn belt'.

"As long as there is a tidal force that affects the planet's rotation, it means that it is too close to the star, then this will be a planet full of radiation and high temperature, and there will be no life at all."

Jiang Yu looked at the "Chaoyang" in the sky: "Although the sun only shows a corner, it seems to be bigger than the normal sun."

"That's true, otherwise there wouldn't be such a long time for Heng Ji Yuan." Yang Dong explained again:
"It is precisely because Trisolaris is close enough to the sun that a stable development period has been formed. This civilization is more advanced than the technology of the post-Han era that we have experienced before.

"The other two stars sometimes pull the trisolaran star away, but the trisolaran star is very lucky, and it can gradually return to the sun every time."

Jiang Yu couldn't help feeling: "It's amazing!"

Yang Dong continued: "I learned from their historical documents that in the distant past, the environment of this planet underwent drastic changes.

"Under that kind of global disaster, some people still insisted on recording the situation at that time."

While talking, she changed the flying direction of the aircraft: "I guess, at that time, it should be when the planet just started to 'lie down'.

"Because the rotation axis has changed greatly, the magnetic field and force field of the entire planet have also undergone obvious changes, so that disaster was caused.

"If a catastrophe of that level happened on the earth, I can guarantee that human beings will definitely become extinct.

"Compared to the creatures on this planet, we are like flowers in a greenhouse, as long as the earth undergoes drastic changes, it will definitely be over.

"Migratory birds will die worse, and their navigation will be out of control in the first place.

"Of course the biggest disaster is that after the direction of the magnetic field changes, the atmosphere changes significantly immediately.

"Direct UV rays, changing oxygen levels, dramatically changing climates, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, ., ., ., ., ., ., . . . . . . . . . ’"

Jiang Yu breathed a sigh of relief: "However, the civilization of the Three-Body Problem has survived."

"Yes," Yang Dong said, "It's really a great civilization."

Jiang Yu quickly reminded: "No matter how great it is, it's fake. Don't get too involved in the drama."

Yang Dong nodded: "I know."

Her tone became a little more cheerful: "I'll take you on a day trip to Trisolaran."

While speaking, the plane had already entered the side of the eternal night, and within a few minutes, the scene outside changed from early morning to dawn, and from dawn to early morning.

Watching the green on the ground rapidly diminish, and finally under the searchlights of the plane, only the bare and cold surface remained.

Jiang Yu couldn't help feeling a little lost in his heart. Fate is indeed too harsh on this planet and civilization.

Just thinking of this, Jiang Yu saw what seemed to be small pieces of light on the ground.

Yang Dong explained: "That's the archaeological team in Yongye, you didn't notice it before, the most active discipline and industry on Trisolaran is archaeology.

"Because receiving the legacy left by previous civilizations is often more cost-effective than developing technology yourself.

"Of course, this also has a huge problem, that is, the technical route of the last civilization may not be correct.

"In this civilization, I took a deep breath and read a lot of historical materials, and found that every civilization on the Trisolaris will spend a lot of energy and try their best to preserve their own history.

"It seems that on this precarious planet, there must be a record of their own civilization in order to prove that they once existed."

After a few seconds of silence, Jiang Yu said: "Maybe this is the way for Trisolarans to survive."

While talking, a goose feather snow suddenly fell outside, Yang Dong looked at the white snow outside and said: "It's very cold here in Yongyemen, it's not suitable for people to live in.

"Yongri Noodles are very hot, reaching a temperature of hundreds of degrees.

"The planet's atmosphere sends the heat in the air here, and at the same time sends a large amount of water vapor.

"On the side of Yongye, the gaseous water condenses into snowflakes, which then fall to the ground."

Jiang Yu smiled and said, "So, wouldn't all the water on the planet fall to Yong Ye Nian's side?"

"That's right," Yang Dong smiled and said, "According to the literature, within a few years of the Heng Era, the Yongri Surface and the 'Dawn Belt' once lost a lot of water due to the special environment.

"At one time, the 'snow mining industry' surpassed the archaeological industry and became the pillar industry of the Trisolarans.

"But the snow they brought back from Yongye is only enough for the residents to drink water, and it doesn't have much effect on the climate.

"It wasn't until they made huge strides in aerospace engineering that they started bringing water from space to Trisolaris.

"The 'Dawn Belt' gradually came back to life."

Everything encountered by this wave of Trisolaran civilization is completely beyond Jiang Yu's imagination: "Bring water from space?"

Yang Dong asked Jiang Yu back: "Do you know how the water on the earth came from?"

Jiang Yu thought about it: "I remember seeing it in some magazine. It came from the universe when the earth was formed."

"Not exactly," Yang Dong said: "After our aerospace industry gradually developed, scholars in related fields discovered that a large part of the water on the earth is accumulated over time.

"Every day, a lot of ice with a diameter of several meters or even more than ten meters enters the atmosphere and joins the earth's water system.

"Because the ice is so small, it has not been found before."

Jiang Yu said "Oh": "There are also many ice cubes like this around Trisolaran?"

Yang Dong guessed: "There should be ice cubes in the state of small celestial bodies in every galaxy, and even in the entire universe."

Then she said: "The situation of the three-body star is better than expected, although there are three stars, it gives people a very hot feeling.

"But the strange thing is that the ice is much denser than the solar system, and there are many large ice asteroids around."

Yang Dong was puzzled and said: "It stands to reason that such dense small celestial bodies are often found around giant gas planets, such as Saturn's 28-kilometer-wide halo.

"Why are there so many small celestial bodies around solid planets like Trisolarans?"
