Annihilation of the solar system

Supersonic flights chase the direction of the rising sun in the stratosphere, because the cruising speed of the aircraft is faster than the earth's rotation linear speed at the latitude on the flight route. Passengers on the plane will see a magical sight, that is, the sun in their eyes

In fact, it is gradually falling from the rising east.

Although the falling speed is very slow, it can still be judged by the morning glow clouds that gradually change from dazzling gold to dim orange. If you just believe your own eyes, then this is undoubtedly a reverse sunrise like a magical world.

But Xia Lan and Wei Xu were not in the mood to appreciate this rare and strange landscape. During the entire flight, they were studying the vast amount of detector data that Veronica gave them.

When arriving in Beijing, the time changed from morning to early morning. Xia Lan arrived at the National Academy of Sciences without stopping. When she arrived at the dean's office, she happened to encounter her father Xia Jigang in the rest area.

Gu Changqing held the photo given by Veronica in his hand and was a little hesitant:

"Jigang, as the Chief Science Advisor of the State Council, you want to give me some advice. Should we report this situation to the superiors or study it ourselves first?"

Xia Jigang paced back and forth and thought for a long time.

"What if there is a problem with these data and they are inducing us to implement an observation plan that wastes people and money?"

Gu Changqing took a deep breath and looked at the photos without saying anything. Xia Lan on the side was a little anxious:

"On the plane, Wei Xu and I have verified that there is basically no possibility of falsification of these data."

"The detector belongs to someone else, and the benchmark data was given by someone else. What do you use to judge it?" Xia Jigang asked impatiently.

"If there is a problem with the data, I am responsible!" Xia Lan argued.

"You can't bear this responsibility!" Xia Jigang's mood changed from impatient to angry.

When Wei Xu saw this scene, he was stunned and did not dare to say anything. Now he could understand how much effort Xia Lan put in the last time the "Yang Jian" space telescope was used. He could also better understand why Xia Lan was on the bench at the space center.

Why is she so fragile?

"You don't need to be responsible, Jigang. You should make a briefing immediately and report the situation to the State Council." Dean Gu's words broke the dull atmosphere full of hostility. After speaking, he handed over a signed blank briefing form.

Gave it to Xia Jigang.

Xia Jigang took the piece of paper and hesitated to speak. He took one last look at Xia Lan and Wei Xu and left the office.

The autumn wind swept the fallen leaves downstairs, making a "swishing" sound. Xia Lan held her forehead with one hand, dragging her exhausted energy and still studying NASA's detection data. Suddenly, the phone rang. The screen clearly displayed -

—Minister Zhong’s name suddenly swept away the tiredness all over his body.

"Minister Zhong! Hello!"

"Hello, Dr. Xia Lan, you haven't had a rest yet!"

"Not yet, what instructions do you have."

"There is a high-level meeting that requires you to attend as an expert. Please prepare the necessary information and I will send a car to pick you up!"

Xia Lan was surprised at first, and then immediately understood what Minister Zhong meant.

"Ok, I see!"

She once again came to the old but brand-new courtyard next to Tiananmen Square. Under the leadership of the security personnel, she came to a hall. The decoration style here was very similar to the hall when she reported last time, but it was much larger.

There is a large long table in the middle. Directly above the table, the chief minister has already taken his seat, and the other people scattered around the table are all regulars on the news network.

The chief looked around for a week, and finally his eyes fell gently on Xia Lan, who was sitting at the other end of the conference table.

"Everyone is here, let's first ask Dr. Xia Lan to introduce the current situation and then give you your professional opinion."

With the experience of the last report, Xia Lan had completely lost her nervousness. She gave a concise and concise statement on the entire discovery process of Oumuamua, the IAU and the airport's later lobby, and then gave her own opinions.

"I think all the evidence now points to those two satellites. Without more international help, it is necessary for us to carry out radio observations with fast 'Sky Eye' as the core! This requires 2/

3 or above, maintain absolute radio silence for at least 12 hours. Only in this way can we confirm our judgment - in addition to observing us, whether alien civilizations are already engaged in secret activities in our solar system."

Xia Lan said something, and there was a quiet discussion among the few participants at the venue.

"If you have any questions, just say them directly. It's so late today, so we've all gathered together. The purpose is to eliminate doubts and make decisions." The chief's words were calm and gentle, but powerful.

The Minister of Defense, wearing the uniform of a general, was the first to ask:

"Dr. Xia Lan, I remember you gave us an analogy last time. Finding clues of alien civilization is like using a magnifying glass to find a grain of sand on a shoe in the entire Beijing. With our own strength, we can

Can we do it? In other words, can we afford the price we pay for it?”

"At the time of the last report, the search area we faced was the entire solar system. This is indeed very difficult for us alone. However, according to NASA's data, we have basically been able to locate the problem that may lie in Europa and Enceladus.

Six satellites. This greatly reduces our detection range and makes it possible for us to implement the plan independently." Xia Lan answered the Minister of Defense's questions clearly.

All the leaders at the meeting carefully recorded every important speech in their notebooks.

"Dr. Xia Lan, does the radio silence you refer to refer to all types of radio communications, such as broadcasts and mobile phones?" asked a leader who often appeared on the news network.

Xia Lan picked up a piece of information from her hand.

"Yes, but it also includes radar, satellites, 5G networks and even high-power lighting equipment and other sources of interference that can produce electromagnetic interference. I have made a list. Please take a look at it."

After speaking, a staff member distributed a copy of the information in Xia Lan's hand to every leader in the venue. The leaders looked at the densely packed forms and sighed softly.

"To implement silence according to the contents on this list is almost equivalent to returning to the farming era without electricity." The leader held the list in his hand and looked at Xia Lan with a solemn expression.

Xia Lan nodded decisively.

"That's basically what you said."

"What about the electromagnetic interference caused by other countries' satellites passing over our territory? We can stop our own satellites, but there is nothing we can do about other countries' satellites!" asked the leader of the Science and Technology Commission.

"We have already considered this issue. We can use the orbit data provided by IAU to know the satellites that pass over our territory during the silent time range, and then find out their communication frequency bands based on the models of these satellites. In the later data processing

, filter out this part of the electromagnetic signal." Xia Lan replied.

After a short period of low-pitched discussion, the Minister of Defense frowned and said solemnly:

"We may be able to withstand the huge impact of silent experiments on the economy. But this standard of silence means that during the silent period, our homeland defense is almost useless. Without communications and satellites, all our weapons and equipment will be lost.

Function. At this time, if an enemy comes..."

Halfway through his words, the Minister of Defense stopped abruptly and looked deeply at the leader who had been silent. The atmosphere in the venue also became solemn.

The leader was silent for a long time, and the discussion in the venue gradually subsided. Everyone's eyes turned to the leader who was deep in thought. No one could imagine what kind of decision-making that was so powerful that Changhong was echoing in his mind at this moment. He looked at

Looking at a place on the conference table without any ornaments, he said calmly:

"The technological level of alien civilization may be beyond our comprehension for the time being. But from a strategic perspective, I think it can be guessed. From the various behaviors shown by that comet, I can see that it is a bit of a warrior, and its potential is

The principle of "risk is short-term" lies in it."

Everyone was listening attentively to the chief's speech.

"If that's the case, it will be too late to make preparations until they are attacked like a forest and an invasion like fire. Therefore, my opinion is that at this moment, the Chinese nation must shoulder the responsibility for the destiny of mankind.

The radio detection plan proposed by Dr. Xia Lan should be implemented. You all should express your opinions and fully discuss it." In the second half of the leader's words, his eyes returned to the participants.

"What about homeland defense..." The Minister of Defense looked at the chief with an anxious and uneasy expression.

The scene suddenly fell silent, and only the depressing sound of breathing reached everyone's ears.

The chief looked around, but still no one spoke.

He stood up slowly and said in a loud voice:

"My opinion is that under military pressure, we must be prepared for all possibilities when experimental observations are feasible."

After another round of discussion, the outcome of the meeting was determined——

The radio astronomy observation plan was passed with silent cooperation.

However, considering that the emergency rescue system and medical system cannot be shut down, the 2/3 of the country's territory proposed by Xia Lan for silence was increased to 4/5 of the country's territory. The observation time was shortened from 12 hours proposed by Xia Lan.

to 10 hours, and ensure a successful detection. This plan is named the 'Sky Eye' plan.

"The plan has been approved, and preparations will begin immediately. I will mention a few points here, and you can refine and supplement the others."

The chief looked at the foreign minister:

"We must inform the United Nations of the specific time of our 'Eye in the Sky' plan, and urge the United Nations to issue an initiative to all countries around the world to implement the 'Eye in the Sky' plan with us for the sake of the destiny of mankind as a whole."

The chief looked at Minister Zhong again:

"You should arrange for the official media to inform the people of this matter in advance, but avoid unnecessary panic and confusion."

The chief turned to the head of the State Council:

"You must mobilize public officials across the country, whether they are at the grassroots level or in government agencies, to do ideological work between enterprises and the people in advance."

Then, he said to the Minister of Defense and the head of the security department:

"You must fully cooperate with the work of the State Council. Especially in the allocation of personnel, priority must be given to the areas where silent work is most difficult."

Afterwards, the chief issued instructions to the person in charge of the Science and Technology Commission:

"Regardless of whether other countries are participating or not, in this 'Sky Eye' project, you must cooperate with Dr. Xia Lan and their observation needs at all costs and without any reason. The purpose of all the work this time is to obtain the observation results from you."

.Your burden is very heavy, you must be able to bear it!"

Finally, the leader's eyes fell on Xia Lan. But the strong and tenacious eyes in his eyes gradually softened:

"Dr. Xia Lan, don't feel pressured for the rest of your work. Just follow your usual procedures. I believe you will be able to successfully complete the task."

After going through many twists and turns, Xia Lan finally got her plan passed.

At the same time, through the discussion in this meeting, she also truly felt the huge price paid by the country and people for this observation experiment.

She had tears in her eyes, but her eyes were firm:

"Guaranteed to complete the mission!"
