"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, and we must confirm that the presumed K2-class civilization really exists. If they do have a Dyson sphere on top of the sun, then they will be able to receive the radio signals we send to the sun. Yes, we want to reach out to them, and no matter what they think and plan for us, we can't go on like this. There was some weakness in Wang Tang's words.

"Has the Führer made up his mind?" After a moment of silence, Zhao Huasheng asked.

"It was the Ministry of Scientific Research that advised the Führer to do this." Wang Tang said, "After sending the message, we will face two results, one, that K2-level civilization has sent us a message back, if this is the case, we can arrange and arrange the next action according to the content of the reply, and second, no one will send us a message back." This situation also represents two possibilities, first, this K2-level civilization chooses to ignore us, since it ignores us, then of course we can't sit idly by, and we must take the next step, whether it is active detection or other methods; Second, this K2-class civilization simply doesn't exist. If they don't exist, it's all the more important for us to take the next step to save our civilization. So...... Logically, if we send a signal that doesn't get a response, we should restart the solar program. ”

"I agree with that statement as well." Zhao Huasheng nodded, "So, which observatory is responsible for this signal transmission?" ”

"The Galaxy Radio Telescope in the Galaxy Observatory that once received the "Wow" signal. ”

The Galaxy Radio Telescope is the largest radio telescope above Earth, with a diameter of up to 500 meters. Of course, such a huge diameter radio telescope will not consist of a pedestal and a huge pot-shaped antenna like a typical radio telescope, because with the level of human technology, it is not possible to support such a huge device on the ground. In fact, it was built in a valley above ground.

It was a basin-like valley with a diameter of 500 meters and a depth of several tens of meters. When the Galaxy Observatory was built, the engineers trimmed the basin, leveled its valley at a certain angle and curvature, and then installed more than 400,000 pieces of aluminum on the mountain wall and bottom of the basin according to certain rules, and also built a bracket to support the signal receiver above the basin. In this way, all radio signals within a diameter of 500 meters will be reflected by these aluminum sheets into the signal receiver above, so that it can obtain the most sensitive signal reception capability on Earth. In terms of theoretical strength, the Galaxy radio telescope can even receive radio signals on Mars 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 a very suspicious character coming from the direction of Sagittarius. There is a certain degree of logical arrangement of signals, so it is unlikely that they are sent by natural phenomena. After receiving this signal, the staff of the Galaxy Radio Telescope was full of shock and wrote a big "wow" on the signal paper to express their surprise, so the signal got the name "wow", which was called the wow signal by subsequent researchers.

The wow signal only appeared once, and for more than ten years after that, the Galaxy radio telescope listened again every month in the original direction, but never received a similar message like the wow signal. Other research institutes on Earth have also been heavily monitoring the direction of Sagittarius, but nothing has been achieved either. Wow Signal just caught a glimpse of it, only to be seen in front of humans for a moment, then vanished, never to be seen again. And what exactly the wow signal represents, no one has been able to decipher it so far.

This is the most powerful and famous radio telescope that is tasked with sending information to the sun.

"Very well, Monzo, let's not go to Equator City first, go to the Galaxy Observatory." Zhao Huasheng said, "Let's witness this incident together. ”

"Okay." Mondra agreed.

"I'm not in the Galaxy Observatory, but it doesn't matter, I'll report this matter to the higher-ups, you go directly, and someone will receive you wherever you go." Wang Tang said, "That's it, goodbye, contact at any time if you have something." ”

"Okay, goodbye." Zhao Huasheng said.

The helicopter spun through the skies, refueled a military base that had not yet been evacuated, and then resumed its journey. About eight hours later, Zhao Huasheng and his party came to the Galaxy Observatory.

The Galaxy Observatory covers a very large area, and even within a radius of 20 kilometers, it is listed as a forbidden area by the government, and it is strictly forbidden for any unrelated people to approach. However, the floor area of the observatory is much smaller, only a small building two kilometers away from the Galaxy radio telescope. All the scientific staff and maintenance personnel of the observatory live here.

The five helicopters that Zhao Huasheng and his party were riding landed in front of Xiaolou. There was already a crowd of people waiting.

"Hello, I am the person in charge of the Galaxy Observatory, and this is a relevant scientist from the scientific research department." A bald middle-aged man walked up, shook hands with Zhao Huasheng, and then introduced Zhao Huasheng.

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

The Galaxy Observatory is now much more populated than ever before. In addition to the original staff and scientists from the Solar Crisis Coordination Center, there are many additional security personnel around the observatory. They were all strong young men, wearing upright military uniforms, with unsmiling faces and looking very imposing.

The personnel of the scientific research department knew Zhao Huasheng's identity, but they didn't say much here, nor did they talk to Zhao Huasheng, they just nodded at Zhao Huasheng, and they could be regarded as having met. When the group walked into the control hall, Zhao Huasheng saw a lot of screens, which were full of flashing data and various charts, as well as lines of red, green, black and white. Zhao Huasheng is not an expert in radio space, so he can't understand these things, but he doesn't ask much.

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

"It's noon." According to the person in charge of the observatory, "The signal is directed at the sun, and the telescope will only be pointed at the sun at noon. You can take a break first. ”

"Nope." Zhao Huasheng said, "Can I go to the telescope and have a look?" ”

"Yes." "It's just a simple routine task for us to send a signal, and we don't need so many people to be here." There is an observation deck next to the telescope, let's go there. ”

So Zhao Huasheng and his entourage, as well as several staff members of the observatory, as well as scientists from the scientific research department, a total of more than 30 people came to the observation deck next to the telescope.

The observation deck is a little higher than the valley next to it, and from the observation deck, you can see the lush jungle in the distance and the huge telescopes reflecting the sun's rays from a thousand meters away.

It's just that the leaves of the lush jungle have shown a little yellow color because of the drop in temperature, although it is a hot summer day, standing on this observation deck, the oncoming mountain breeze also brings some coolness.

"This is probably the last time we'll use this observation deck." The person in charge of the observatory lamented, "In the future, the weather will get colder and colder, and we will stay in the base and never come out again, except for the necessary telescope maintenance work." ”

"Why, aren't you going to evacuate to Equatorial 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 doesn't have the funds and the ability to rebuild such a big thing. We are the ears of humanity to listen to the sounds of the universe, and we must stay here. ”

"In addition to this observatory, there will be at least 30,000 institutions on the earth, and more than five million staff will not be evacuated to Equateur City." "Among these institutions, there are energy factories, coal mines, oil fields, nuclear power plants, scientific research institutions, and so on. None of these things can be relocated. ”

Zhao Huasheng nodded slightly. This is a necessary institution for the continuation of human civilization, and someone must stand up and stand up for these posts.

"Fifteen minutes before the signal is transmitted." The head of the observatory raised his wrist, looked at his watch, and said.

Zhao Huasheng didn't seem to hear this. Zhao Huasheng's gaze crossed the distance of a thousand meters and landed in the huge valley in the distance. Hundreds of thousands of fast aluminum flakes melted into one piece at this distance, they reflected the sun's rays, and Zhao Huasheng's eyes narrowed slightly. There was no vegetation or animal signs within three hundred meters of the valley, but three hundred meters away it was full of vegetation and the occasional howl of wild beasts.

Under the faint sunlight, the entire huge galaxy radio telescope reveals a quaint and desolate taste.

"It's time." said the head of the observatory.

At the same time, Zhao Huasheng seemed to hear a buzzing sound, slightly low, but very powerful. When it comes into people's ears, it makes people feel a little dizzy even in their heads.

The head of the observatory didn't seem to feel this. He suddenly opened his mouth and said loudly: "Hello respected unknown civilization, these are some voices from the human civilization on the third planet of this small solar system......"
