The Chinese Sky Eye system, which Hawking called the device most likely to make contact with aliens. In 2021, China publicly announced that the Sky Eye is open to the outside world, and the cosmic signals it receives and the range that can be explored shock the scientific community of all countries! ---- primer
Hello everyone, I'm a polytechnic man. From ancient times to the present, human beings are full of reverie about space, in ancient Chinese mythology, the sky is divided into nine heavens, the nine heavens live with a variety of gods, in ancient Egypt or ancient Greek mythology there are also a variety of gods living in the sky, although these are myths, but the ancient people always believe that they exist. In modern times, with the continuous development of science and technology, human beings have gradually invented high-tech space exploration instruments such as astronomical telescopes and satellites, and their understanding of the universe has been further deepened.
Even more and more information reveals that there may really be creatures in the universe that we do not understand, and in the field of astronomical exploration that we do not understand, human beings seem to be engaged in a battle for space exploration, and all countries want to take the initiative in this war. Of course, our country cannot be left behind. The achievements of China's astronomical exploration cause are obvious to all, in addition to the launch of a number of satellites, there is also a device that makes the world marvel, that is, China's sky eye system. Many friends may know about him from Hawking's mouth, Hawking said before his death that the Sky Eye system may be the first device to contact aliens. So what kind of device is this, and what strange information has it found in space?

China's Tianyan is one of the most famous astronomical telescopes in the world, and its main mission is to explore the universe. It is worth mentioning that China's Sky Eye is completely a single-aperture spherical radio astronomical telescope independently designed by China, and the independent design means that China fully owns the intellectual property rights of this equipment, which is a milestone achievement for China's space exploration work. From the perspective of aperture alone, China's sky eye system is the world's largest astronomical telescope today, the caliber reaches about 500 meters, such a large aperture emission area is unimaginable to ordinary people, some people have simply calculated, the sky eye emission area at least has to be equivalent to 30 football fields so large. If thirty football pitches don't have any concepts, Ascendas will transform them into concrete tangible objects for you.
If you use the standard bottle of mineral water to calculate, if you want to fill it, you need to put about four bottles of it into each person around the world, and everyone can make up for the picture. In addition to the large area of China's sky eye, there is also a feature that is the exploration distance. Some people have done experiments, China's sky eye system is by far the world's farthest astronomical telescope. Its theoretical irradiation distance is 13 billion light years away, Ascendas explains to you what is the theoretical irradiation distance, that is to say, the irradiation range of our heavenly eye should be around this number, it is possible to be higher than this number or lower than this number. Ascendas also wants to tell you why this number is, because this number is the edge of the universe known to mankind today.
In addition to the illumination distance and area, it must be mentioned that this astronomical telescope is by far the most responsive single-aperture astronomical radio telescope in the world. For a variety of radio signals from space, the telescope is able to capture them instantaneously. From these three alone, it is not difficult to see that China's heavenly eye system is already standing at the peak of the world. The famous scientist Hawking has also publicly evaluated China's heavenly eye, saying that with this system, China is most likely to become the first country to contact aliens. It can be seen how powerful the heavenly eye of our country is. It is also very difficult to build such an excellent astronomical telescope, and even in the preparatory stage, it has been questioned by all walks of life.

None of China's top technologies are easily obtained. The same is true of the construction of the Celestial Eye. First of all, if you want to build a hemispherical telescope of such a large caliber, the field you need is a problem. There are two options for the choice of site, the first is the man-made plan, and the second is to rely on the natural terrain. After many rounds of discussion by Chinese experts, it was concluded that the second scheme is more reliable. Therefore, China quickly set up a geological expedition team to survey thousands of low-lying areas of similar shape in China. The seemingly simple work is difficult, because from the map alone, there is no ugly thing at all, and it is necessary to map the specific data of the depression in the local area. Area is the first priority, after the area condition is reached, the shape must be round enough, because if the shape is not round enough, the equipment cannot be erected.
The area is large enough, the shape is round, but it can not accumulate water, because as long as the water is accumulated, the entire equipment is prone to rust, which not only affects the service life but also affects the sensitivity of the telescope. The above three are just the basic conditions. Everyone should think that this depression is naturally formed, not artificially created, and it is not easy if the above three conditions are satisfied. It sounds very difficult, but in fact it is really not easy, this depression alone, our scientists have been looking for nearly 10 years. Ten years after the establishment of the project, Nan Rendong, a famous scientist in China, finally found this big depression in Guizhou. This can also be described as a ten-year grinding sword. After the location is chosen, construction is also a huge problem. Because China's sky eye system is different from other astronomical telescopes in the world, it can only be built with new technologies.
In this process, China's craftsmen have also created many world firsts and the world's largest, for example, in the construction of the device reflector surface of the Sky Eye and the feeder cabin, the world's first steel cable weaving technology was created. This technology was also used in the construction of many bridges in the later period. The reflector surface of the Celestial Eye device is actually a large iron mesh, which is woven from 7,000 steel cables, each of which is hung on top of a ring beam supported by nearly fifty huge steel columns. In addition, there are also many small organs on top of this large net, and scientists in our country have set up a small unit of reflective surface for each small grid. Some data show that these small units have a total of nearly 4500 pieces. There are about 400 types involved. In order to achieve the adjustment of these unit surfaces, Chinese scientists have also added adjustment devices to these unit surfaces, which are downswitches, and the number of these lower cables is also very amazing, with about 2300.
Having said that, let's talk about the feeder cabin known as the pupil. China's feeder module is different from the feed capsule of other countries, and the feed chamber of astronomical telescopes in other countries is fixed, and our feed chamber is mobile and adjustable. This technology enables the feeder cabin to acquire the radio wave signal as widely as possible. This technology is also the world's first, and it is believed that this technology should be frequently seen in future astronomical telescope construction projects. In fact, China's Tianyan, as the world's largest astronomical telescope, applies many world-first technologies, and these technologies can be taken out at will to hang other countries for many years.
At the end of the first quarter of 2021, China announced that the Tianyan system began to open to the outside world, and as soon as the news came out, a large number of astronomical enthusiasts came to visit from thousands of miles, and I believe that with time, there will be more and more news about Tianyan technology and Tianyan discovery being announced. In the next period of time, cosmic science enthusiasts around the world will surely obtain more extraterrestrial information through the Celestial Eye. This practice of resource sharing is also a confirmation of that sentence, science has no borders, technology has no borders, and if you want to develop better, human beings must learn to share resources, only in this way can more scientific and technological innovation come out.
Well, will China's Sky Eye system become the world's first human technology to contact aliens? Welcome to leave a message for Tengge, and finally like Tengge's article, remember to pay attention.
