Annihilation of the solar system

Wei Xu put the heavy suitcase into the car and said to Xia Lan in the cab with a bit of complaint:

"There are still a few hours before the flight takes off. Why are you going to the airport so early? The breakfast pasta in the departure hall is terrible and expensive."

"Teacher Shen said she wanted to see us off before we set off and let us go to her home."

Hearing Xia Lan's words, the irritation on Wei Xu's face immediately disappeared. He quickly closed the back cover and jumped into the car.

"Oh, Teacher Shen asked us to go, so let's go there quickly!"

Xia Lan and Wei Xu arrived at Shen Manling's home. A sumptuous Western-style breakfast was already placed on the dining table, which made Wei Xu's eyes sparkle. Shen Manling was holding a glass plate filled with fruit salad, her face full of elegance. said with a smile:

"You are in a hurry to go to Brussels this time, and you have to work overtime during the day and night. So I have no choice but to send you off with breakfast."

Wei Xu stared at the food on the table, and his stomach was already rumbling.

"Thank you so much, Teacher Shen. I eat box lunches with my senior sister every day, and I'm almost losing weight!"

"Hurry up and sit down, let's talk while we eat."

After sitting down, Wei Xu didn't care about the details of the knife, fork and plate, and started eating with his chopsticks. Shen Manling didn't mind either. She must have understood her lover's desire for food.

"Do you have any ideas for the next detection plan?" Shen Manling asked.

Xia Lan took out a few pieces of information from her backpack and handed them to Shen Manling:

"In the past few days, we have consulted a lot of literature and asked teachers in other majors. Existing observation results show that no habitable planets have been found within a hundred light-years around the solar system, and Oumuamua did use insects behind Jupiter. Information is transmitted through the hole, so we speculate that the parent star of alien civilization should be very far away from the earth."

Speaking of this, Xia Lan's face became solemn:

"At the same time, we also discovered that in the past 144 years, an object similar to 'Oumuamua has appeared in the solar system every 12 years. This phenomenon shows that the other party's observations of us show accurate periodicity. So we speculate, These 'Oumuamua may not have arrived in the solar system through a long voyage from their parent star, otherwise they would not have such accurate periodicity."

The smile on Shen Manling's face disappeared, replaced by a rare seriousness. She put the information in her hand on the table:

"But your speculation is somewhat unreasonable. 'Oumuamua itself is as big as an aircraft carrier. If it came through a wormhole, why didn't they directly send their space fleet to the solar system to achieve their goal? , wouldn’t it be simpler? Moreover, once a wormhole with a mass like Oumuamua is opened, the gravitational waves generated will be obvious, and conventional gravitational wave detectors can directly detect this phenomenon.”

At this time, Zhou Cheng was walking downstairs while talking:

"I also have similar questions to your teacher Shen. I have calculated before. If we want to send a spacecraft the size of an aircraft carrier to the solar system, the total energy required is equivalent to the total energy produced by the sun in ten years. .

This is a very terrifying order of magnitude. Moreover, this is purely the amount of energy required. If you include the conversion efficiency, it is an astronomical figure. You must know that the mass-to-energy conversion rate of nuclear fusion is less than 1%.

If the opponent is a civilization that can master such terrifying magnitude of energy control, then the opponent may only need to send out one battleship to easily wipe out all humans on the earth."

Wei Xu and Xia Lan both stood up and shouted in unison:

"Teacher Zhou!"

Zhou Cheng walked to the dining room and motioned for them to sit down:

"Tell me and your teacher Shen your complete guesses."

Xia Lan nodded and said:

"We have three speculations. One is that 'Oumuamua itself may be composed of two parts. Its shell and most of its mass are captured natural celestial bodies, and the real 'Oumuamua is hidden inside. The real 'Oumuamua may be detoured.

The back side of Jupiter appears later, but we can no longer observe it. Secondly, the real 'Oumuamua came from a wormhole, and the location of that wormhole may be the opponent's outpost here, but in order not to be

Our gravitational wave detector detected it, and the specific location may be at least a light-year distance from the solar system. The third is the real 'Oumuamua, which should be a series of equipment, maybe detection equipment, or some other equipment

"Theoretically, the mass will not be too great, but it will have strong kinetic energy production capabilities."

Xia Lan's words aroused Zhou Cheng's interest:

"It is logically self-consistent and consistent with our observations. Go on."

Wei Xu swallowed the steak in his mouth with great effort, and there was still black pepper sauce on his mouth:

"We now believe that the real 'Oumuamua, in addition to detecting us, may also be doing some secret things in the solar system, but we can't think of it for the time being. But considering the communication delay problem caused by the distance, logically speaking,

What they are doing is most likely operating according to a set program, and launching a new one every 12 years is to confirm whether the planned program is consistent with the actual situation."

Wei Xu hesitated and looked at his senior sister. Xia Lan understood what he meant:

"But there is something unreasonable about our guess. If they find that the actual situation is inconsistent with the plan, they will not be able to make timely adjustments."

Zhou Cheng was very satisfied with Xia Lan and Wei Xu's guesses and pondered for a moment:

"If they find that the actual situation deviates from the planned program, then they may use quantum entanglement's long-distance communication method to make real-time adjustments."

Shen Manling lowered her eyebrows lightly:

"If they have the ability to conduct quantum long-distance communication, why do they need to create wormholes to send back data in real time? Can't they just use quantum entanglement communication to send back data directly?"

A smile appeared at the corner of Zhou Cheng's mouth and he looked at his wife:

"Manling, as an astronomer like you, you may not be very clear about this. According to the existing theory, in order to achieve quantum communication, you must first prepare quantum pairs in an entangled state, and then place the entangled quanta separately. Only in this way can you

By changing the properties of one quantum, the properties of another quantum in the entangled state are changed in real time, thereby achieving long-distance communication."

Shen Manling, Xia Lan and Wei Xu, three astronomy majors, listened carefully to Zhou Cheng's explanation.

"But for such communication, each entangled quantum pair can only be used once before losing the entangled state. Simply put, ultra-long-distance real-time communication has traffic limits and is very expensive. If a large amount of data needs to be transmitted back, I think

Quantum communications are not necessarily more energy efficient than their current means."

With the support of Zhou Cheng's theoretical physics, this bold speculation gradually became complete, and at the same time it began to become scary. Because once it is established, it means that the earth will most likely be attacked by other civilizations at some time in the future. attack. Judging from the current situation, humans have almost no ability to resist.

"Well, now this series of speculations seems to be very self-consistent. So how are you going to find them in the solar system now?" Shen Manling asked.

Xia Lan said:

"If we assume that they are really active and working in the solar system, then electromagnetic wave signals will be generated. Then we can detect their radio wave signals through radio telescopes."

Shen Manling nodded:

"This method is good and theoretically valid. However, the electromagnetic waves they radiate should be very weak, so your actual operation may be very difficult."

Wei Xu picked up another croissant from the table:

"Well, so our plan is to gather radio telescopes from all over the world to form a radio astronomical telescope array with the diameter of the earth, just like we took pictures of the M87 black hole last time, to detect the electromagnetic waves they may emit. But... .”

Wei Xu stopped and looked at Xia Lan.

"It's just that considering that their behavior is very covert, the wavelengths and frequencies they use should be equivalent to the wavelengths and frequencies most commonly used on the earth, so that they will be submerged in the earth's very complex electromagnetic environment.

If a highly sensitive radio antenna like our fast sky eye in the mountains of Kaizhou cannot shield electromagnetic environmental pollution, it may not be able to detect anything." Xia Lan added what Wei Xu had not finished.

Shen Manling and Zhou Cheng looked at each other and fell into thinking.

Xia Lan took a shallow breath and said:

"The difficulty of our plan does not lie in the observation equipment, but in the cooperation of radio silence."

Shen Manling hesitated. Although it is not easy to use radio telescopes around the world, it is possible to implement it. But the main problem now is that in this information age, global radio silence is needed. That means everything from satellite communications to the ground Radio stations need to be shut down in cooperation to achieve the clean electromagnetic environment they envision, which is basically an impossible task.

Zhou Cheng calmed down and said: "Well, let's put aside the difficulty for now. Your plan is the most likely to make discoveries. You go to the International Astronomical Union to propose a plan first this time. Let's see what the European experts say. If there are difficulties , let’s find a solution together.”
