In theory, it is not dangerous for the Earth to cross the asteroid belt.

Although there are more than 500,000 planets in the asteroid belt, these asteroids are evenly distributed in the orbit around the sun of more than 200 million kilometers between Mars and Jupiter, and the average distance between asteroids is more than 300,000 kilometers.

If it is just an ordinary spacecraft, you can easily find a safe channel to cross the asteroid belt.

But the earth is different. The diameter of the earth is as high as 12,700 kilometers and the mass is as high as 5.965*10^21 tons. Such a huge celestial body crosses the asteroid belt, which is enough to cause large-scale disturbances to asteroids within millions of kilometers near the Earth's waterway.

The journey through the asteroid belt is as high as 200 million kilometers, and it takes nearly two months.

In the meantime, if an accident occurs, asteroid with a diameter of more than 100 meters may fall into the Eurasian continent or North American continent, which may cause large-scale downtime of planetary engines.

If the planetary engine is shut down, the earth will accelerate and slow down, and coupled with a series of subsequent chain reactions, what is waiting for the earth is likely to be a catastrophe.

Not to mention, humans can only predict the orbits of asteroids with a diameter of more than 500 meters. A large number of asteroids with a diameter of less than 500 meters so far are difficult to observe.

To this end, the Earth's coalition government began preparations decades ago.

In order to deal with asteroids, humans have brought out the most powerful weapon, antimatter bomb, ever.

When building the ring-equator planet engine, humans simultaneously built a ring-equator superparticle collider.

It is through this collider that over the past thirty years, humans have accumulated a considerable amount of antimatter.

Once the Earth officially begins to cross the asteroid belt, the space fleet will conduct large-scale reconnaissance and use antimatter bombs to destroy asteroids with a diameter of more than 100 meters on the channel.

As for asteroids with a diameter of less than 100 meters, they can only be resisted by the earth.

The Earth aims the southern hemisphere in the direction of its advance as the main impact area of ​​the asteroid.

Most of the southern hemisphere is mainly based on the marine environment, and immigration has been completed. There is no problem of carrying asteroids without building planetary engines.

In addition, in order to respond to the possible crisis this operation, the coalition government has formed a team of consultants composed of top global scientists to provide intellectual support for the operation.

Pang Xuelin was also selected as a scientific consultant team for this operation.

The reason is not the high-purity carbon nanotubes he led to the development of. Although the current birth of carbon-based chips has enabled humans to create more powerful supercomputers.

What the coalition government mainly valued him was his achievements in mathematics.

In recent years, Pang Xuelin has made another mathematical achievement in the wandering earth plane with the BSD conjecture. The top mathematician and materials scientist are enough to get him into the sight of the highest leadership of the Earth's coalition government.

...

Early this morning, Pang Xuelin woke up from his dream.

Yao Bingxia, who was sleeping beside him, had already gotten up and could faintly smell the fragrance of his wife remaining in the quilt.

Pang Xuelin got up from the bed, washed, brushed his teeth, and then came to the restaurant.

Yao Bingxia was busy in the restaurant wearing an apron, with clear porridge, pickles, steamed buns and other breakfasts on the table.

"Brother Kobayashi, you're up, and you still have two fried eggs, so it's good later!"

Soon, Yao Bingxia came out with a plate containing two poached eggs. The two sat together and had a warm breakfast.

After breakfast, Yao Bingxia found a neatly ironed tie and suit jacket for Pang Xuelin from the room, changed it to him, and handed him the suitcase he had prepared long ago, saying: "This time I go to the United Government headquarters, you should be careful on the way. Now the spaceship faction outside is starting to make a fuss again. It is a huge mistake to say that the earth's crossing the asteroid belt, and humans will pay a heavy price for it. I heard from Brother Gao that the spaceship faction terrorist organization "Starry Wings" may attack the scientists who went to the United Government headquarters to support this operation..."

Pang Xuelin smiled and said, "Don't worry, they are just clowns who can't jump for long. Besides, the routes we chose are all confidential. They don't know which flight we take at all, and even if we want to do it, they can't find the target!"

Yao Bingxia said: "It's best if you're okay. I'm not by my side to take care of you for three months this time, but don't forget to eat as you used to when you get busy with work!"

"I understand, my little housewife!"

Pang Xuelin reached out and scraped the bridge of her nose.

Yao Bingxia gave him a blank look, handed the briefcase to Pang Xuelin, went up and hugged Pang Xuelin hard, then stood on tiptoe and pecked Pang Xuelin's lips, and smiled and said, "Okay, it's getting late, hurry up and leave!"

"Then I'm leaving!"

The two bid farewell to each other.

Pang Xuelin came out of his home, and several soldiers downstairs who were responsible for guarding him had been waiting for a long time.

A short buzz cut and extremely capable man stepped forward and saluted: "Hello, Professor Pang, I am Wang Lei, the captain of the Earth Defense Army, and I am ordered to carry out the mission of escorting you."

Pang Xuelin was slightly stunned. After so many years, he came to the wandering earth world. This was the first time he had seen a famous and surnamed character in the movie.

Wang Lei is one of the protagonists of the movie. In the end, in order to protect the heroine Han Duoduo, he sacrificed his life on the Sulawesi No. 3 steering engine.

In the movie, his wife and children were both in the Jiangcheng No. 1 Dungeon, but were eventually killed because the flint that restarted the Jiangcheng No. 1 engine failed to be delivered in time.

Pang Xuelin carefully observed it again. In the movie, Wang Lei's subordinates, Liuzi, Gangzi, Zhou Qian and others who had appeared in it were also there.

"Captain Wang, thank you for your hard work this time!"

Pang Xuelin and Wang Lei shook hands.

"No, no, no, Professor Pang, it is our honor to be able to escort you!"

Wang Lei looked a little excited, and even had a hint of admiration in his eyes when he looked at Pang Xuelin.

In the Dungeon No. 1, Jiangcheng, Pang Xuelin is a famous figure.

This is not only because of his identity as vice president of Jiangcheng University, but more importantly, as the inventor of high-purity single-wall carbon nanotubes, Pang Xuelin successfully solved the core problem of carbon-based chips and was one of the promoters of the new generation of human information revolution. Under the intentional or unintentional publicity of the government, Pang Xuelin has a great reputation all over the world, and is well-known in Jiangcheng No. 1 Dungeon.

Therefore, for Wang Lei and the others, seeing Pang Xuelin was like seeing a legendary figure.

"Okay, the time is almost over, let's go!"

Under Wang Lei's leadership, the group went straight to the underground hangar and boarded a transport plane.

The transport aircraft was then pushed into a large lift platform and rushed straight to the ground airport. Then, the aircraft engine was started and flew directly to Siberia.

The Earth Engine General Control Room is located in a dungeon twenty kilometers deep in the underground of Siberia. It is also the headquarters of the Earth United Government.

Since the southern hemisphere is the direction of advance when the Earth passes through the asteroid belt, the safety of the northern hemisphere covered with planetary engines is relatively high. The closer to the North Pole, the lower the probability of being hit by the asteroid.

The Earth Alliance Government located in Siberia is one of the safest areas.
