Earth Era

"Send a message?" Zhao Huasheng was a little surprised by this statement, "What message to send? Why send a message?"

"Things have come to this point, we have to confirm whether the speculated K2-level civilization really exists. If they really have placed Dyson spheres on the sun, then they must be able to send radio signals to the sun if we send them to the sun." Received. That's right, we want to take the initiative to contact them, no matter what thoughts and plans they have for us, we can't go on like this." Wang Tang's words were a little weak.

"Has the head of state made up his mind?" Zhao Huasheng asked after a moment of silence.

"It was the Ministry of Scientific Research who suggested the head of state to do this." Wang Tang said, "After sending the message, we will face two results. First, the K2 civilization sent us a message back. If this is the case, we can rely on the content of the reply. Arrange and arrange the next action. Second, no one has replied to us. This situation also represents two possibilities. First, this K2 civilization chooses to ignore us. Since it ignores us, of course we cannot sit still and must Take the next step, whether it is active detection or other methods; second, this K2-level civilization does not exist at all. If they do not exist, we must hurry up and take the next step, so as to to save our civilization. So... logically, if we don't get a response to our signal, we should restart the solar exploration program."

"I also agree with this statement." Zhao Huasheng nodded, "So, which observatory is responsible for the signal launch?"

"The Xinghe radio telescope in the Xinghe Observatory that once received the "Wow" signal."

The Galaxy Radio Telescope is the largest radio telescope above the earth, with a diameter of up to 500 meters. Of course, a radio telescope with such a huge diameter will not be composed of a base and a huge pot-shaped antenna like ordinary radio telescopes, because with the level of human technology, it is still impossible to support such a huge device above the ground. In fact, it was built in a valley in the ground.

It was a basin-shaped valley with a diameter of 500 meters and a depth of tens of meters. When the Xinghe Observatory was built, engineers trimmed the basin, leveled its valleys according to certain angles and curvatures, and then installed more than 400,000 pieces of aluminum on the walls and bottom of the basin according to certain rules. A scaffold to support the signal receiver was erected above the basin. In this way, all radio signals within a diameter of 500 meters will be reflected by these aluminum sheets to the signal receiver above, allowing it to obtain the most sensitive signal receiving ability on the earth. According to the theoretical strength, the Xinghe radio telescope can even receive radio signals on Mars that are equivalent to the strength of mobile phone communications.

The most famous "wow" signal in the history of extraterrestrial life exploration was also received by it.

The "Wow" signal is a radio signal with very suspicious characteristics coming from the direction of Sagittarius. The signal has a certain logical order, so it is unlikely to be emitted by natural phenomena. After receiving the signal, the staff of the Xinghe radio telescope wrote a big word "Wow" on the signal paper in shock to express their surprise, so the signal got the name "Wow". It was called the wow signal by subsequent researchers.

The Wow signal only appeared once, and within ten years after that, the Xinghe radio telescope would monitor again in the original direction every month, but never received any news similar to the Wow signal. Other research institutes on the earth have also conducted a lot of monitoring in the direction of Sagittarius, but they also failed to gain anything. The wow signal just had a glimpse, and it disappeared in front of human beings only for a moment, and never appeared again. As for what the wow signal means, no one has been able to decipher it so far.

This time, it is the most powerful and famous radio telescope that is in charge of sending information to the sun.

"Very good, Monjo, let's not go to Equator City, but to the Xinghe Observatory." Zhao Huasheng said, "Let's witness this incident together."

"Okay." Monjo agreed.

"I'm not in the Xinghe Observatory, but it doesn't matter. I will report this matter to my superiors. You can go directly, and someone will receive you there." Wang Tang said, "That's it, goodbye, and contact me anytime .”

"Okay, goodbye." Zhao Huasheng said.

The helicopter turned in the sky, and after resupplying in a military base that hadn't been evacuated, it embarked on the journey again. About eight hours later, Zhao Huasheng and his party came to the Xinghe Observatory.

The Xinghe Observatory covers a very large area, and even within a radius of 20 kilometers, it has been listed as a restricted area by the government, and any unrelated personnel are strictly prohibited from approaching. But the building area of ​​the observatory is much smaller, only a single small building two kilometers away from the Xinghe radio telescope. All the scientific research personnel and maintenance personnel of the observatory live here.

The five helicopters that Zhao Huasheng and his party took landed in front of Xiaolou. There was already a group of people waiting there.

"Hello, I'm the person in charge of the Galaxy Observatory. This is a relevant scientist from the Scientific Research Department." A bald middle-aged man came up, shook hands with Zhao Huasheng, and then introduced to Zhao Huasheng.

"Hello, I'm Zhao Huasheng." Zhao Huasheng nodded.

There are many more people in Galaxy Observatory now than before. In addition to the original staff and scientific researchers from the Solar Crisis Coordination and Processing Center, there are many more security personnel around the observatory. They were all strong young men, wearing formal military uniforms, with unsmiling faces, and looked very imposing.

The staff of the scientific research department knew Zhao Huasheng's identity, but they didn't say much here, and they didn't talk to Zhao Huasheng. They just nodded to Zhao Huasheng, which was regarded as meeting. When a group of people walked into the control hall, Zhao Huasheng saw many screens, which were full of flickering data, various charts, and lines of red, green, black, and white colors. Zhao Huasheng is not an expert in radio astronomy, so he doesn't understand these things, but he didn't ask too much.

"When was the signal sent?" Zhao Huasheng asked.

"It will be noon." The person in charge of the observatory introduced, "The signal is directed at the sun. Only at noon, the telescope will be facing the sun. You can take a rest first."

"No." Zhao Huasheng said, "Can I go to the telescope to have a look?"

"Yes." The person in charge of the observatory said, "It's just sending a signal. This is just a simple routine task for us. We don't need so many people to guard here. There is an observation deck next to the telescope. We go there."

So Zhao Huasheng and his party, several staff members of the observatory, and scientists from the scientific research department, a total of more than 30 people came to the viewing platform next to the telescope.

The viewing platform is higher than the valley next to it. Standing on the viewing platform, whether it is the lush jungle in the distance or a thousand meters away, the huge telescope reflecting the sun's rays can have a panoramic view.

It's just that the leaves of the lush jungle have shown a little withered and yellow color due to the drop in temperature. Although it is a hot summer, standing on this viewing platform, the mountain wind blowing in front of you also brings some coolness.

"This is probably the last time we use this viewing platform." The person in charge of the observatory sighed, "The weather will get colder and colder in the future, and we will stay in the base and never come out except for necessary telescope maintenance work. "

"Why, don't you evacuate to Equator City?" Zhao Huasheng asked.

"Of course not." The person in charge of the observatory shook his head: "If we evacuate, what will happen to the telescope? You know, the current human government does not have the funds and ability to rebuild such a big guy. We are humans listening to the voice of the universe. ears, we must stay here."

"In addition to this observatory, there will be at least 30,000 institutions on the earth, and more than 5 million workers will not be evacuated to Equator City." Mengzhuo said indifferently, "Among these institutions, there are energy factories, coal mines, Oil fields, nuclear power plants, scientific research institutions, etc. These things cannot be relocated."

Zhao Huasheng nodded slightly. This is a necessary institution to maintain the continuation of human civilization, and someone must stand up and stick to these positions.

"There are still fifteen minutes before the signal is launched." The person in charge of the observatory raised his wrist, looked at his watch and said.

Zhao Huasheng didn't seem to hear this sentence. Zhao Huasheng's eyes crossed the distance of a thousand meters, and put his eyes on the huge valley in the distance. Hundreds of thousands of fast aluminum sheets melted into one piece at this distance. They reflected the sun's rays, which made Zhao Huasheng's eyes narrow slightly. There is no vegetation within 300 meters around the valley, and there are no traces of any animals. The 300 meters away is full of vegetation, and occasionally the howling of wild animals can be heard.

Under the slightly weak sunlight, the entire huge galaxy radio telescope reveals a simple and desolate taste.

"It's time," said the person in charge of the observatory.

At the same time, Zhao Huasheng seemed to hear a faint buzzing sound, which was slightly low, but very powerful. It spread into people's ears, making people feel a little dizzy even in their heads.

The person in charge of the observatory does not seem to feel this. He suddenly opened his mouth and said loudly: "Dear unknown civilization, hello, these are some voices from the human civilization on the third planet in this small solar system..."
