The Science Fiction World of Xueba

The meeting will start soon.

The first to speak was the Chief Executive Officer of the United Earth Government, an old man with a European face.

"Hello, everyone. It is a great pleasure to meet all the experts and scholars here. All of you here are the top scientists on our planet. Most of them are old acquaintances. Of course, there are some new faces joining us today. I hope that in the next In the meeting, no matter whether it is a new face or an old man, everyone can speak freely. The earth's crossing of the asteroid belt is a risky decision made by the coalition government, but it is also a risky decision to use Jupiter's gravitational slingshot effect to accelerate the earth and escape the solar system. A decision of last resort.”

"Fortunately, such a crossing only needs to be done once. In the remaining few revolution cycles, we can let the earth pass along the edge of the asteroid belt harmlessly. Therefore, this crossing can be said to be the earth's crossing The last adventure before Jupiter’s rendezvous. In this adventure, there may be many dangerous scenes beyond our expectations, such as the earth being hit by a giant asteroid, such as the possibility of a large-scale shutdown of the planetary engine after the impact, and for example, extreme forces will Use this opportunity to launch an attack on our earth engine..."

"There will be many difficulties, and there may be many uncontrollable accidents. Of course, the coalition government and the military will do their best to eliminate non-scientific factors, but for purely scientific factors, you need to rely on the strength of everyone here. What I want to say is Now, let’s invite the Secretary-General of the Joint Government Science Committee to speak!"

There was a burst of thunderous applause in the conference room. This time, it was an old man with an oriental face who spoke.

Pang Xuelin knew him. This is the Chinese scientist Liu Xin who proposed the refusion planetary engine plan and the Wandering Earth Project together with Kazuo Nakata. He is one of the three giants of the coalition government and is also the secretary-general of the Science Committee. For ten years he held the position and is now an old man past his seventies.

Liu Xin said: "Mr. Seedorf has already told everyone about the importance of this operation. Next, let me talk about some problems and details that may arise during the voyage of the earth through the asteroid belt."

Liu Xin paused, and continued: "Before the meeting started, we have already sent you the scheduled route of the earth and the orbital parameters of the asteroids in the asteroid belt that we have observed so far over 500 meters. Everyone has read the relevant information, and the route we chose is also a safe route calculated by a supercomputer."

"However, for asteroids with a diameter of less than 500 meters, our current observation capabilities are limited. In addition, these asteroids are always in motion, and the early warning time we can do is very limited. In fact, any asteroid with a diameter of 100 meters , Asteroids with a mass of more than 10,000 tons falling into the earth, especially falling into the northern hemisphere, may cause devastating damage to our planetary engines, thus triggering a series of chain disasters. At present, one of our preliminary plans is that the distribution of the space fleet Cleanup missions are carried out within a radius of 1.5 million kilometers around the earth, and at the same time the earth provides detection and early warning. Once an asteroid with a diameter of more than 100 meters is found to enter this range, the asteroid will be blasted with an antimatter bomb.”

"It is estimated that the time for the earth to pass through the asteroid belt is about 50 days. At present, we are still more than five million kilometers away from the asteroid belt. It is estimated that the earth will officially enter the asteroid belt in half a month. Therefore, the next two You must provide all-round intellectual support for this operation here, and I hope everyone can understand."

"Okay, that's all I want to say. Next, if you have any opinions or suggestions about this operation, you can bring them up for discussion at the meeting."

After Liu Xin's words fell, the conference room was quiet for a while, and gradually fell into whispered discussions.

Soon, some scientists raised their hands to speak.

"I have a question,

Are we stockpiling enough antimatter bombs? What is the thrust redundancy of our engines? What is the explosion limit that a planetary engine can withstand? "

The conference room gradually fell silent, and everyone turned their gazes to the few people sitting on the rostrum.

"Let me answer this question!"

This time, it was a middle-aged man in military uniform who spoke, apparently from the military.

"We have stored more than a thousand antimatter bombs, which can destroy at least a thousand asteroids that may threaten the earth. You don't have to worry about this. In addition, the redundancy of the engine is about 30%, and we can withstand more than 1,000 asteroids. Thirty percent of the planetary engines lose their thrust. As for the explosion limit that the planetary engines can withstand, we have used supercomputer simulations. Even a megaton-level hydrogen bomb will not damage the planetary engines unless it directly hits the planetary engines. If it is an asteroid impact, generally only an asteroid with a diameter of more than 100 tons or a diameter of more than ten meters directly hits the planetary engine, which may have an impact on the planetary engine."

"Thank you for your clarification, I have no questions for now!"

The scientist nodded in satisfaction.

Immediately afterwards, another person raised his hand and said, "Just now Secretary-General Liu also said that our current alert range is about 1.5 million kilometers, and the main targets of the space fleet are still asteroids with a diameter of more than 100 meters. However, according to my calculations, in fact, if an asteroid between 50 meters and 100 meters hits the northern hemisphere, it may have a very disastrous impact. I would like to ask, when it is found that the impact is inevitable, and the space fleet When there is no way to destroy the asteroid, can the earth turn its direction in time so that the asteroid falls accurately into the southern hemisphere?"

Liu Xin replied with a smile: "We can do this, which is why we require the space fleet to set up a warning circle of 1.5 million kilometers. When collisions with certain high-threat targets are unavoidable, we can actively adjust them." The asteroid’s landing zone should minimize losses as much as possible. This is why everyone needs to be a staff member here, because there are high-threat targets, and everyone here needs to make correct decisions. At that time, whether it is the coalition government or the space fleet, They will follow your orders directly!"

"Thank you Secretary-General Liu, my problem is gone!"

At this moment, Pang Xuelin raised his hand and said, "I have a question!"

After the words fell, everyone's eyes involuntarily focused on Pang Xuelin.

Although most of the people here recognized Pang Xuelin's qualifications to participate in this meeting, but when such a young man appeared in the meeting, his every move would become the focus of everyone.

"Professor Pang, please tell me!"

Liu Xin's eyes fell on Pang Xuelin, feeling relieved, expecting, and curious.

It was at his request that Pang Xuelin was chosen to attend this meeting.

After all, in the past few years, Pang Xuelin was considered the most popular scientist in China.

In addition to his outstanding achievements in the field of carbon nanotubes and graphene, this little guy even solved the BSD conjecture problem that has plagued the mathematics community for nearly a hundred years at a young age.

At the same time, he has made remarkable achievements in the fields of pure mathematics and engineering. Such compound talents are extremely rare in this era.

Because Pang Xuelin is too young and his qualifications are too low, although Liu Xin has noticed him in the past few years, he has been letting him stay in the front line of scientific research. On the one hand, he will see if he can achieve more outstanding achievements; There is also a qualification for him to wait for a while, and when the time is right, he will be directly transferred to City of Hope and become a member of the Science Committee of the United Earth Government.

It's just that the risk of the earth crossing the asteroid belt this time is too great, and intellectual support is urgently needed, so Liu Xin took this opportunity and directly named Pang Xuelin.

Pang Xuelin said: "I would like to ask, is there any way for our space fleet to urgently expand the warning circle? After all, the warning circle with a radius of 1.5 million kilometers is still a bit narrow. Once a relatively fast asteroid enters the earth's waterway , we don’t necessarily have enough reaction time.”

After Pang Xuelin's words fell, Liu Xin couldn't help but feel a little disappointed. He also wondered if this young man could offer some unexpected opinions or suggestions, but this question was a little too well-behaved.

At this time, the middle-aged man in military uniform said: "Professor Pang, the warning circle of 1.5 million kilometers has reached the limit of the space fleet. If the warning area is expanded, it is very likely that fish will slip through the net. Once If there is a problem, then there will be big trouble."

Pang Xuelin seemed not surprised by the answer from the middle-aged man in military uniform. He smiled slightly and said, "Then, I have an idea. Not only can the space fleet's alert range be expanded, but it can even be used within 10 million kilometers of the earth's waterway, with a diameter of more than ten meters. The asteroids can be effectively observed, I wonder if you are interested?"

"What?"

After Pang Xuelin's voice fell, the entire conference room suddenly became silent. Everyone stared at Pang Xuelin dumbfounded. Why is this guy so shameless when he brags at such a young age?

If he could do what he said, then why would the big guy have such a meeting? They could just leave, and the United Earth Government and the military could easily allow the Earth to pass through the asteroid belt unscathed.

Even Liu Xin, who had always had a certain promise to Pang Xuelin, looked at Pang Xuelin with some headaches, wondering if he had done something wrong to bring him to Hope City, this guy, how can he speak so unreliably!

"Comrade Pang Xuelin, this is a formal government meeting, and no jokes are allowed. You must be responsible for every word you say!"

Liu Xin looked at Pang Xuelin seriously.

Pang Xuelin smiled slightly and said seriously: "Secretary Liu, I guarantee with my academic reputation that although my idea is a bit wild, it is indeed feasible to a certain extent, but the specific implementation details need to be supplemented by everyone here."
