The Science Fiction World of Xueba

The meeting started soon.

The first to speak was the chief executive of the United Earth Government, an old man with a European face.

"Hello everyone, I'm glad to meet with all the experts and scholars here. All of us here are the top scientists on our planet, most of whom are old acquaintances. Of course, there are some new faces joining today. I hope to continue in the future. In the conference, everyone can speak freely, whether it is a new face or an old man. The Earth ’s crossing of the asteroid belt was a risky decision made by the coalition government, but in order to accelerate the Earth and escape the solar system with the help of Jupiter ’s gravitational slingshot effect A last resort decision. "

"Fortunately, such a crossing only needs to be done once. With the remaining several revolution cycles, we can let the earth pass harmlessly along the edge of the asteroid belt. Therefore, this crossing can be said that the earth is in contact with the The last adventure before Jupiter meets. This adventure may have many dangerous scenes beyond our expectations, such as the earth being hit by a giant asteroid, such as a planetary engine may encounter a large-scale shutdown after being hit, and for example, extreme forces will Take this opportunity to launch an attack on our Earth engine ... "

"There will be many difficulties, and there may be many uncontrollable accidents. Of course, for non-scientific factors, the coalition government and the military will make every effort to eliminate them, but purely scientific factors need to rely on the strength of everyone present. What I want to say is For these, I have asked the Secretary-General of the Scientific Committee of the United Government to speak! "

雷 A thunderous applause soon sounded in the conference room. This time, an old man with an oriental face was speaking.

Pang Xuelin knew him. This is the Chinese scientist Liu Xin who proposed the fusion planetary engine plan and the Stray Earth plan together with Kazuo Nakata. He is one of the three giants of the joint government and the secretary general of the Scientific Committee. He has held this position for ten years, and is now an old man who has lived for a long time.

欣 Liu Xin said: "Mr. Seedorf has just talked to you about the importance of this operation. Next, I will talk about some issues and details that may occur during the course of the Earth's voyage through the asteroid belt."

Liu Xin paused and continued: "Before the start of this meeting, we have sent to you the scheduled routes of the earth and the asteroid orbital parameters of more than 500 meters in the asteroid belt we have observed so far. You have already read the relevant information, and the channel we chose is also a safe channel calculated by the supercomputer. "

"However, for asteroids less than 500 meters in diameter, our current observation capabilities are limited, coupled with the fact that these asteroids are always in motion, the warning time that can be done is very limited. In fact, any one hundred meters in diameter Asteroids with a mass of more than 10,000 tons and falling into the earth, especially in the northern hemisphere, may cause devastating damage to our planetary engines, which will cause a series of chain disasters. One of our initial plans is the distribution of the space fleet A cleanup mission is performed within a radius of 1.5 million kilometers around the earth. At the same time, the earth provides detection warnings. Once an asteroid with a diameter of more than 100 meters is found to enter this range, it will be blasted with an antimatter bomb. "

"The time it takes for the earth to pass through the asteroid belt is about 50 days. At present we are more than 5 million kilometers away from the asteroid belt. It is expected that the earth will officially enter the asteroid belt after half a month. Therefore, the next two Everyone must be here to provide all-round intellectual support for this operation, I hope everyone can understand. "

"Okay, that's all I want to say. Next, if you have any comments or suggestions about this action, you can come up and discuss it at the meeting."

欣 Liu Xin's words fell, and the conference room was quiet for a little while, and gradually fell into a whisper.

Soon, some scientists raised their hands to speak.

"I have a question, is there enough anti-matter bombs in our storage? What is the thrust redundancy of our engine? What is the explosion limit that the planetary engine can withstand?"

The conference room gradually quieted down, and everyone turned their attention to the people sitting on the podium.

"Let me answer this question!"

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

"We have stored more than a thousand antimatter bombs, which can destroy at least thousands of asteroids that may pose a threat to the earth. Do n’t worry about this. In addition, the redundancy of the engine is about 30%, and we can afford more than 30%. Thirty percent of planetary engines lose thrust. As for the explosion limits that planetary engines can withstand, we have used super-computing simulations. Even if a million-ton hydrogen bomb does not directly hit the planetary engine, it will not affect the planetary engine. If the impact of an asteroid strikes, only asteroids with a diameter of more than 100 tons or a diameter of more than 10 meters will directly hit the planetary engine.

"Thank you for your confusion, I have no problem for now!"

The scientist nodded with satisfaction.

Immediately afterwards, another person raised his hand and said, "Secretary General Liu also said that our current alert range is about 1.5 million kilometers. The main target of the space fleet is asteroids with a diameter of more than 100 meters. However, according to my calculations, if the asteroids between 50 meters and 100 meters hit the northern hemisphere so far, they may also have extremely serious impacts. I would like to ask when the impact is found to be inevitable and the space fleet When there is no way to destroy the asteroid, can the earth reverse its direction in time so that the asteroid falls into the southern hemisphere accurately? "

Liu Xin answered with a smile: "We can do this, which is why we ask the space fleet to set up a 1.5 million-kilometer alert ring. When some high-threat targets are unavoidable, we can take the initiative to adjust The asteroid's landing zone minimizes losses. This is why everyone needs to be a staff here. Because high-threatening targets appear, everyone here needs to make correct decisions. At that time, whether it is the coalition government or the space fleet, Will listen directly to your instructions! "

谢谢 "Thank you, Secretary General Liu, my question is gone!"

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

The utterance of the words fell, and everyone's eyes were involuntarily focused on Pang Xuelin.

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

"Professor Xiao Pang, please say it!"

欣 Liu Xin's gaze fell on Pang Xuelin, with comfort, expectations, and a hint of curiosity.

He chose Pang Xuelin to attend this meeting, which he requested.

After all, in the past few years, Pang Xuelin is regarded as the most powerful scientist in China.

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

At the same time, it has made remarkable achievements in the field of pure numbers and engineering. Such composite talents are extremely rare in this era.

Because Pang Xuelin is too young and his qualifications are too low, although Liu Xin has paid attention to him in the past few years, he has always allowed him to stay on the front line of scientific research. On the one hand, he can see if he can achieve more outstanding achievements. He was also asked to go through his qualifications and be transferred to the City of Hope directly when appropriate, becoming a member of the Scientific Committee of the United Earth Government.

It is just that the risk that the Earth ran through the asteroid belt was too great, and urgently needed intellectual support, so Liu Xin took this opportunity to directly click on Pang Xuelin's name.

Pang Xuelin said: "I want to ask if our space fleet urgently needs to expand the alert circle. After all, the alert 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 response time. "

Xi Pang Xuelin's words fell, and Liu Xin could not help but feel a little disappointed ~ www.readwn.com ~ He also wondered if this young man could come up with some more unexpected opinions or suggestions, but this question was too normal.

At this time, the former middle-aged man in the military uniform said, "Professor Pang, the 1.5 million-kilometre alert ring has reached the limit of the space fleet. If the alert range is further expanded, it is likely to cause a fish to leak the net. If there is a problem, then the trouble will be great. "

Pang Xuelin didn't seem to answer the middle-aged man in military uniform with a slight smile: "Then I have an idea, not only can I expand the alert range of the space fleet, but even enter the earth's waterway within 10 million kilometers, with a diameter of 10 meters or more Asteroids can be effectively observed, I wonder if you are interested? "

"what?"

Pang Xuelin's voice dropped, and the entire conference room was quietly audible. Everyone looked at Pang Xuelin with a stunned look. Why is this guy so young that he is so shameless?

If he can do what he said, what big guy has a meeting, it can be dispersed directly, the United Earth Government and the military can easily let the earth pass through the asteroid belt without any damage.

Even Liu Xin, who has been holding Peng Xuelin for a period of time, looked at Pang Xuelin with a headache and wondered if he had done it wrong to get him to Hope City. This guy, how to say it is so unreliable!

"Comrade Pang Xuelin, we are a formal government meeting, we must not make any jokes, every word you say must be responsible!"

欣 Liu Xin looked at Pang Xuelin seriously.

Xi Pang Xuelin smiled and said positively: "Secretary General Liu, I guarantee with my academic reputation. Although my ideas are a little bit wild, they do have some feasibility. They are just specific implementation details and need to be supplemented by everyone present."
