FAST is built in a natural karst giant col in Tai Wo Tai. The terrain here is undulating, the landform type is simple, and the local mountains are steep, forming steep cliffs and overhangs. Hao Qiuyan came out of Lukou of Guiyang Airport, did not stop, the distance of 180 kilometers was smooth, and it took about two and a half hours to arrive.

The two main scientific objectives of FAST are to survey neutral hydrogen in the universe and observe pulsars to explore the origin and evolution of the universe. The former can study the large-scale physics of the universe, and the latter can study the structure and laws of matter in extreme states. And, of course, the search for possible interstellar communication signals and the search for extraterrestrial life.

Due to the high sensitivity of FAST, the number of objects that can be observed will increase dramatically due to the ability to see farther and fainter objects. By detecting interstellar molecules and searching for possible interstellar signals, the probability of finding extraterrestrial civilizations will increase by 5 to 10 times.

The observation frequency that large radio is good at is medium and low frequency, and the high-frequency submillimeter wave and millimeter wave field also need stronger telescopes to form a relatively complete observation system. What I'm thinking about now is that only by broadening the dimension of science and technology can we penetrate the fog of the universe.

Generally speaking, most telescopes belong to optical telescopes, which are mainly observed by the human eye, and can be divided into refractive telescopes, reflecting telescopes, and catadioptric telescopes. However, the human eye cannot see the radio radiation from celestial bodies that are too far away and from various celestial bodies.

Li Rendong picked him up downstairs, and they talked as they walked. Hao Qiuyan asked about the situation, "Have you received any information recently?" "FAST is already running down this road. Hao Qiuyan paused, "I don't want to make rash judgments about the progress of research based on subjective understanding alone, this is a comprehensive system and careful analysis." Most of the countries in the world are involved in the search for aliens. The non-governmental, governmental, and participatory, most of them scientists from all over the world, showed unprecedented cooperation. Li Rendong said, "We are working hard all the time, and there is no time to relax, what a mission and task [the Blu-ray Project] is, and we dare not have any slackness." ”

They walked up to the elevator and pressed the button. The two of them didn't say anything more. The elevator rose rapidly, quietly crossed the floor of the mezzanine, and came to the main control room of the comprehensive building. The working host and the on-site monitoring and control screen are working, and FAST receives about 2 T of information every day for storage and processing. There were a lot of people in the hall, and under the large electronic screen was a collective operating table, each at their own work.

Sitting down at one end of the hall, Lee continued, "If we hear something credible, we should think about anything else." ”

Hao Qiuyan thought for a moment, "What do other scientists think?" ”

"As for the voice of the 'extraterrestrial visitor', Hawking, as an important member of the monitoring program, once issued a warning, hoping that radio telescopes in the world that can listen to cosmic signals will not answer any suspicious signals."

"Don't answer, don't answer, don't answer. In the universe of belief in the dark forest, exposing oneself is tantamount to being wiped out. I can understand people's concerns and will not actively send signals. ”

"We send it to data processing centers in Beijing and Guiyang for analysis."

"In the future, if our human interstellar warships sail beyond the solar system, pulsars will become veritable beacons in the vast sea of stars. FAST has only received a faint signal from outer space, and it cannot be confirmed that it is transmitted back from Midi. But I've always felt that Midi knows how we receive information, and he knows what to do.

"On September 17, 2016, we received suspicious signals. After the relevant experts deciphered the alien signal, they were surprised when they cracked it, and it was a warning signal from aliens. As the commander-in-chief of China's extraterrestrial observations, how should you view this issue? ”

Hao Qiuyan, "On the night of September 17, Mi Di and I were on Phoenix Mountain. As for receiving high-quality suspicious pulsar signals from afar, from the obtained frequency phase map, the scientists calculated the distance of the pulsar from Earth. Since pulsars gradually slow down as they rotate, the difference in energy between how fast and slow they rotate is converted into radiation, which is picked up by the FAST telescope. Seems quite normal. ”

Li Rendong, "I can't tell whether it is related to the 'Phoenix Mountain Incident', Qian Lei sees the overwhelming '1351 light years', and every time he feels a faint sadness, in some conspiracy theory title parties, 1351 light years is even more of a headache." ”

"Whether it's conspiracy theories or premeditation theories, there are some things that we simply don't understand. According to the state of existence in the dimensional space we are in, high-level aliens, that is, god-level civilizations, are several dimensional spaces higher than us, can you still think that some things are taken for granted? Sometimes, we need to use Tai Chi thinking to understand a problem. ”

"However, how many people can master Tai Chi thinking?"

"Yes, Tai Chi thinking is a new way of thinking, which is compatible with the material thinking of Western culture and the material thinking of Eastern culture. Tai Chi thinking is the essence of Chinese dialectical thought, which 'overall's all easy-to-learn thinking. ”

"Scientists can't engage in scientific research and learn Tai Chi thinking at the same time, then they won't have enough energy."

"Everyone has their own strengths."

"Regarding extraterrestrial civilizations, countries around the world have discussed quite enthusiastically."

"It's fair to say that the first contact between two civilizations can be a threat to each other. Because this is a matter of global choice, there should be no response to any signal without proper international consultation, and this should be an international consensus. But the current state of the earth is that it is a knife to stretch out the head and shrink the head is also a knife. The atmosphere leaves two windows for humans to explore the universe, one optical and the other radio. For astronomers, if an optical telescope is a microscope, then a radio telescope is a CT machine that obtains the ultrafine structure of celestial bodies. FAST is a powerful tool for detecting extraterrestrial planets, especially terrestrial planets. Due to its high sensitivity, it can see farther and weaker objects, and by detecting interstellar molecules and searching for possible interstellar communication signals, the chances of finding extraterrestrial civilizations are 5 to 10 times higher than existing equipment. Radio waves are electromagnetic waves that propagate in the form of TEM waves (transverse electromagnetic waves); Quantum communication is based on the efficient and absolute security of quantum information transmission, and has become the mainstream of earth communication, for human beings on earth. There will not be one type of communication for star civilizations, and electromagnetic waves contain many types, arranged in order of frequency from low to high: radio waves, infrared, visible light, ultraviolet rays, X-rays, Y-rays. Humans on Earth use radio waves, but it should also be considered that the science and technology of extraterrestrials is N billion years higher than that of Earth; Is the contact method they use the same as we use? Our quantum communication is only in its infancy.

There is also the induced magnetic wave, which is a changing electric field that produces a magnetic field, and a changing magnetic field produces an electric field. However, the mechanical laws of the electric field are very similar to the mechanical laws of the gravitational field (Coulomb force F=KQq/2, gravitational force (Earth) F=GMmR/2, are the Coulomb force and gravitational force two different manifestations of the same force? Just like the wave-particle duality of light, one is the property of a large number of photons, and the other is a property of a small number of photons. The Coulomb force is the property of the force exhibited by a small number of electrons, while the gravitational force is the property of a macroscopic substance composed of a large number of electrons (electrons in an atom). So a changing electric field can produce a magnetic field, and can a changing gravitational field produce a magnetic field? In turn, the changing magnetic field can create a gravitational field, thus forming a gravitational wave in the process of alternating generation? This kind of magnetic wave, we are still hypothetical; And this hypothetical wave is capable of carrying a greater amount of information, greater concealment and greater penetration.

Many scientists and thinkers have devoted a lot of energy and even their lives to exploring the universe, and magnetic waves are still stuck in our imagination. According to the theory of yin and yang space, we are in the material space, which belongs to the masculine space. The 4th and 5th dimensions are neutral spaces, and further up are feminine spaces. We're just kindergartens in space, and the alien highly intelligent race can even treat us like zoo animals. ”

Across the firmament, radio signals from the stars reach the surface of the radio telescope's massive butterfly-shaped antenna, even during the day and in adverse weather conditions without interference. Nowadays, the radio map emitted by the body has been detected and known by various countries, so it can be assumed that if the star is not not observed on the detection screen or output device, it is obscured by some vehicle (flying along the realization between the radio telescope and the star). If more such ground detection devices are used, as long as all the aircraft fly through the visual area of the radio telescope, the aircraft can be accurately positioned in three dimensions through triangulation calculations, and the accuracy rate is very high.

After thinking hard, Li Rendong was deeply touched, "We still have a long way to go, and now we have realized the leap from tracking imitation to integrated innovation." This kind of gap will be difficult to do, but we have not given up, and it is impossible to give up. The continuous enhancement of scientific and technological innovation gives us the confidence to explore deeper into the universe and achieve breakthroughs in cutting-edge scientific fields. ”

Hao Qiuyan, "This matter has nothing to do with Mi Di's loss of contact, but there are always doubts and I can't say it clearly." ”

Li Rendong, "What doubts? ”

Hao Qiuyan raised his head and looked at the high ceiling, "I can't tell you clearly, you find out the signal you received, and I'll listen to it." ”

came to the secret room and took out the information disk and put it on the playback device for him to listen to, Hao Qiuyan listened to the noise coming from the headset:

A (called 1, called 2)—B (called... Call 1)—B(~Call],—2) in (1—Call 1, 1—Call 2, W1.

B(—2, a brick])—B(—W]—2, W2(1—1, 1, W1, 2).

C(1,—called 1-2)—B(1—called 1,1—called 2,W1—B(2,w—masonry 1(—W]—called 2.

D—masonry 1 (—W] — call 2, call 1, call 2) — B (call... Called 1) (—2, a brick]) B (—W).

Li Rendong, "Many scientists can't tell, but that day, the signal was good, and people were intoxicated. The runway for the international competition of pulsars is at a time when the international radio astronomy community is competing with each other. Maybe it's just a very common reception, scientists think about problems based on scientific thinking. You have an unusual mind, I know that, you should have your point of view. ”
