The meeting began quickly.

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

"Hello everyone, it is a pleasure to meet with all the experts and scholars here, all of you are the top scientists on our planet, most of them are old acquaintances, of course, there are some new faces joining in today, I hope that in the next meeting, whether it is a new face or a previous old man, everyone can speak freely. Earth's passage through the asteroid belt was a risky decision made by the coalition government, but it was also a last resort decision to accelerate the Earth and escape the solar system with the help of Jupiter's gravitational slingshot. ”

"Fortunately, such a crossing only needs one time, and with the remaining few orbital cycles, we can allow the Earth to pass harmlessly along the edge of the asteroid belt. Therefore, this crossing can be said to be the last adventure of the Earth before its conjunction with Jupiter. This adventure may lead to many dangerous scenarios beyond our expectations, such as the impact of the Earth by a giant asteroid, the possibility of large-scale shutdown after the impact of the planetary engine, and the possibility of an attack on our Earth engine by extremist forces......"

"There will be a lot of difficulties, and there will be a lot of uncontrollable accidents. Of course, the coalition government and the military will do their best to eliminate non-scientific factors, but purely scientific factors need to rely on the strength of everyone here. That's all I have to say, and now I give the floor to the Secretary General of the Scientific Committee of the Coalition Government! ”

There was a thunderous round of applause in the conference room, and this time, it was an old man with an eastern face who spoke.

Pang Xuelin knows him, this is Liu Xin, a Chinese scientist who jointly proposed the refusion planetary engine program and the Wandering Earth Program with Kazuo Nakata, one of the three giants of the coalition government, and also the secretary general of the Science Committee.

Liu Xin said: "Mr. Seedorf has just told you about the importance of this operation, and next, I will talk about some problems and details that may arise during the Earth's voyage through the asteroid belt. ”

Liu Xin paused and continued: "Before the start of this meeting, we have 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 that are more than 500 meters high. ”

"However, for asteroids with a diameter of less than 500 meters, our current observation capabilities are limited, and these asteroids are always in motion, so the warning time we can make is very limited. In fact, any asteroid with a diameter of 100 meters and a mass of more than 10,000 tons falling into the Earth, especially in the Northern Hemisphere, has the potential to cause devastating damage to our planetary engines, triggering a series of cascading disasters. At present, one of our preliminary plans is that the space fleet will be distributed within a radius of 1.5 million kilometers around the earth to carry out clean-up missions, and at the same time, the earth will provide reconnaissance and early warning, and once an asteroid with a diameter of more than 100 meters is found to enter this range, it will use antimatter bombs to blast the asteroid. ”

"The time for the earth to cross the asteroid belt is expected to be about 50 days, and we are still more than five million kilometers away from the asteroid belt, and it is expected that the earth will officially enter the asteroid belt in half a month. Therefore, for the next two months, you must be here to provide all-round intellectual support for this operation, and I hope you can understand. ”

"Okay, that's all I have to say, and then, if you have any comments or suggestions about this operation, you can come up with them and discuss them at the meeting."

Liu Xin's voice fell, and the conference room was quiet for a while, and gradually fell into a whispered discussion.

Soon, 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 room fell silent, and everyone turned their eyes to the people sitting on the podium.

"I'll answer that question!"

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

"We have more than a thousand antimatter bombs in stockpile, and you don't have to worry about destroying at least a thousand asteroids that could pose a threat to Earth. In addition, the redundancy of the engine is about 30 percent, and we can withstand more than 30 percent of the planetary engine losing thrust. As for the explosion limit that the planetary engine can bear, we have used supercomputing simulation, even if the megaton hydrogen bomb does not directly hit the planetary engine, it will not have much impact on the operation of the planetary engine, if it is an asteroid impact, generally only an asteroid of more than 100 tons or more than 10 meters in diameter directly hits the planetary engine, it is possible to have an impact on the planetary engine. ”

"Thank you for your doubts, I don't have a problem for the time being!"

The scientist nodded in satisfaction.

Immediately afterwards, another person raised his hand and said: "Secretary-General Liu also said just now that our current warning range is about 1.5 million kilometers, and the main target of the space fleet is still an asteroid 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 also cause extremely serious effects. ”

Liu Xin replied with a smile: "We can do this, which is why we require the space fleet to set up a 1.5 million kilometer warning circle, when some high-threat targets are unavoidable, we can take the initiative to adjust the asteroid's landing area to minimize the damage." That's why you need to be here as staff officers, because when there are high-threat targets, you need to make the right decisions here, and whether it's the coalition government or the space fleet, you will be directly under your command! ”

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

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

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

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

"Professor Xiao Pang, please speak!"

Liu Xin's eyes fell on Pang Xuelin, with relief, expectation, and curiosity.

The choice of Pang Xuelin to participate in this meeting was requested by him.

After all, in the past few years, Pang Xuelin has been the most popular scientist in China.

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

At the same time, he has made remarkable achievements in the field of pure numbers and engineering, and such compound talents are extremely rare in this era.

Because Pang Xuelin is too young and too young, in the past few years, although Liu Xin has noticed him, he has been letting him stay in the front line of scientific research, on the one hand, to see if he can achieve more outstanding achievements, on the other hand, there is also a way for him to boil up his qualifications, and when the time is right, he will be directly transferred to Hope City and become a member of the scientific committee of the United Earth Government.

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

Pang Xuelin said: "I want 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 channel, we may not have enough reaction time." ”

Pang Xuelin's voice fell, Liu Xin couldn't help but feel slightly disappointed, he also wondered if this young man could put forward a few opinions or suggestions that were more unexpected to everyone, but this question was too decent.

At this time, the middle-aged man in military uniform before said: "Professor Pang, the 1.5 million kilometer warning circle has reached the limit of the space fleet, if the warning range is expanded, it is very likely to lead to the occurrence of fish that slip through the net, once there is a problem, then it will be a big trouble." ”

Pang Xuelin didn't seem surprised by the middle-aged man's answer in military uniform, and said with a slight smile: "Then, I have an idea, not only can I expand the warning range of the space fleet, but even can effectively observe asteroids with a diameter of more than ten meters within 10 million kilometers of the earth's shipping lane, I don't know if you are interested?" ”

"What?"

Pang Xuelin's words fell, and the entire conference room suddenly fell quietly, and everyone looked at Pang Xuelin in amazement, this guy is so young, why is he so shameless when he brags?

If he can do what he said, what kind of meeting will the big guy have, he can just disperse, and the United Earth government and the military can easily let the Earth pass through the asteroid belt unscathed.

Even Liu Xin, who has always had certain expectations for Pang Xuelin, looked at Pang Xuelin with a little headache, did he do something wrong to get him to Hope City, this guy, why is he so unreliable!

"Comrade Pang Xuelin, this is a formal government meeting, we can't make any jokes, everything you say must be responsible!"

Liu Xin looked at Pang Xuelin with a serious expression.

Pang Xuelin smiled slightly, and said: "Secretary-General Liu, I vouch for my academic reputation, although my idea is a bit fanciful, it does have a certain feasibility, but the specific implementation details still need the help of everyone here." ”
