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

Chapter 225 Orphan Planet
After sending reporter Xu away, Jiang Yu said to No. [-]: "Go and find out how Bai Xiao's relatives and descendants are doing now.

"If life is not going well, ask them if they would like to join the Federation of Wallfacers.

"Don't let the dead heroes chill!"

Number three nodded: "Yes."

Jiang Yu said again: "I'll go to the City Hall later, name the square outside 'Pioneer Square', and erect a monument to Bai Xiao and the others as a hero behind the enemy lines.

"For Bai Xiangdong and Baker, erect a monument for their outstanding contributions to the Wallfacer Federation!"

No. [-] agreed, and just about to go out, Jiang Yu said again: "Help me find an astronomer. I'll take a good rest today and come see me tomorrow morning."

After going out on the [-]rd, Jiang Yu, who hadn't slept for two days and one night, felt tired, but couldn't fall asleep anyway.

It was around 21:[-], when he entered the sleepy stage in a daze, it seemed that a young man suddenly whispered in his ear: "We wanted to have a drink together when we came to Beijing, but I didn't expect that we never had the chance. "

Jiang Yu woke up suddenly, looking at the empty room under the dim light, his heart felt a little empty.

They only met once in the "Three-Body" game, and only met Wei Keke once more in reality.

It stands to reason that there should be no friendship, but when Jiang Yu heard the news of their sacrifice, he felt like he had received the news of the death of an old friend.

Jiang Yu looked at the ceiling and sighed: "Hey, they're all gone."

When the others left, he would continue to fight. Fortunately, he was no longer fighting alone.

It wasn't until midnight that Jiang Yu finally fell into a deep sleep.

The next day, he finished washing early and had breakfast, and immediately asked Number Three to invite the astronomer.

The astronomer looked like he was in his thirties, but Jiang Yu estimated that he was at least 50 years old.

Recently, Jiang Yu found that people in Guanghan City look almost the same after they are 27 or 70 years old, and they look almost the same until they are 70 years old, and they start to age again after [-] years old.

Residents of Guanghan City use "mature adults" to describe this age group that cannot see age changes, so as to avoid any unnecessary misunderstandings.

This "mature" astronomer is a typical oriental man, wearing a white coat that is standard for staff members in Guanghan City, short hair, and somewhat peachy eyes.

Seeing the Wallfacer, he was very excited: "Hello, Wallfacer, my name is Hu Guanghan, you can call me Xiaohu."

Jiang Yu shook hands with him, thinking that you should not be "Little Hu"!

He had read the information brought by No. [-], and this "Little Hu" seemed to be in his fifties.

No. [-] on the side hurriedly introduced: "This is Director Hu of the Department of Astronomy at Lunar University. He is the first batch of newborns born in Guanghan City, so his parents named him Hu Guanghan."

No. [-] paused and said again: "Director Hu is one of the researchers who participated in the 'Reinforce the Future' project."

Hu Guanghan said excitedly: "Yes, yes, my parents admire you very much. They have said more than once that I am a child of Guanghan City, and I am also your child."

No. [-] held back his laughter from the side.

Jiang Yu smiled awkwardly: "Thank you for your family's support, please sit down."

Hu Guanghan sat very stiffly opposite Jiang Yu. After making tea for them on the [-]rd, Jiang Yu said, "I called Director Hu here today to ask you some questions about astronomy."

"Please say."

"I'm very curious about Orphan Planet, so I want to ask Director Hu to talk about Orphan Planet."

When talking about his professional problems, Hu Guanghan's expression became much more relaxed: "The Orphan Planet is also called an interstellar planet or a wandering planet..."

"Liu, what are you wandering about?" Jiang Yu felt as if he had heard something extraordinary.

"Wandering planets!" Hu Guanghan said again: "The astronomical community believes that these planets should originally revolve around the stars.

"But because of the influence of other planets or gravitational sources outside the planetary system, it was thrown out of its own planetary system.

"According to observations and guesses since the last century, the number of orphan planets should be quite large!
"There are twice as many planets the size of Jupiter, or giant gas planets, and countless smaller planets.

"They have been shuttling between planetary systems and planetary systems, and only by accident will they be captured by the star's gravity."

Hu Guanghan paused and continued: "More than 40 years ago, the Hubble II telescope observed an orphan planet passing by the outer reaches of the solar system.

"But because it was too dark there, I just knew it existed, but didn't get any detailed information.

"It wasn't until five years later that the orphan planet was far away from the solar system, and we couldn't see it."

Jiang Yu thought for a few seconds and asked again: "Is the formation of the orphan planet your guess, or has it been confirmed?"

"It's our guess." Hu Guanghan's excitement at the beginning gradually calmed down, and he answered the question more logically:
"First of all, it is impossible for the space dust between planetary systems to form planets, let alone the large gas giant planets, it is even more impossible to form from dust.

"So when we discovered orphan worlds, we rejected the hypothesis that they formed outside of our planetary system.

"Then there is only one logic that makes sense, they must have formed within the galaxy and left the planetary system for some reason.

"At the beginning of the formation of the planetary system, the orbits between the planets are very unstable.

"Taking the solar system as an example, Uranus, which is 'lying down' in the outer reaches of the solar system, may have been 'lying down' under the pull of Jupiter's huge gravity when it met Jupiter a long time ago.

"Astronomers once speculated that Uranus may have formed in the inner solar system, and then migrated to the outer solar system under the gravitational push of other planets.

"Now we feel that the solar system is very stable, but this stage is very stable. At the beginning of its formation, the sun should be very violent and chaotic.

"The so-called we believe that at the beginning of the formation of each galaxy, there is a high probability that a few stars will be thrown out of the planetary system."

Jiang Yu was greatly surprised by what Hu Guanghan said. Before, he thought that there would not be too many orphan planets.

Sure enough, professional problems should be solved by experts.

But he still asked: "Is it possible that some orphan planets are intelligent life itself, pushing the planets they live on out of their own planetary system?"

Hu Guanghan was taken aback: "They have no reason to do this, the gap between the planetary systems will be very cold, and some areas may even be close to absolute zero.

"In this state..."

Jiang Yu said: "Just tell me, can my hypothesis be realized?"

Hu Guanghan thought about it: "It should be possible. If you master the full application of gravity, you should be able to throw the planet you live in out of the planetary system."

Jiang Yu asked again: "Using some large-scale nuclear engines, can we provide the planet with the power to leave the planetary system? I will use the earth as an example."

Hu Guanghan shook his head with a smile: "The force required is too great, and with current science and technology, it is impossible to build such a powerful engine.

"Even if we have a new breakthrough in the use of nuclear energy, and we can really create such an engine, it may take more than ten years to push the earth out of orbit and go to the outer reaches of the galaxy."

Jiang Yu nodded: "Then tell me in detail, the method you just said to use gravity to power the planet!"
