Are there really aliens in the universe? Is UFO really an aircraft for aliens to visit the earth? Previously, Dalian hosted the first World UFO Conference. Researcher Wang Sichao from Purple Mountain Observatory attended the meeting and introduced his research report on a series of UFO phenomena over the past 20 years. Yesterday, he was interviewed by a reporter and unveiled the mystery of UFOs for the public. UFO is not equal to alien spacecraft. Researcher Wang Sichao first pointed out that UFO is not equal to an alien spaceship. UFO (commonly known as flying saucer) is the abbreviation of "UnidentifiedFlyingObject", which refers to all unidentified or unidentified flying objects, but there may be aliens visiting the earth. Researcher Wang Sichao gave an example. Before a flight landed at Changzhou Airport on September 7th, the radar detected 4-5 UFOs in the air that could not be observed by naked eyes. The object disappeared naturally after hovering for more than an hour. The regulatory authorities showed that no high-altitude balloon was launched that day, which could not show its height, shape and volume, and ruled out the possibility of birds. Wang Sichao said that it is difficult to determine what it is now. This is a typical UFO phenomenon. Due to the lack of relevant information, UFO is not a problem that can be solved in a short time. He thinks it may be a special plane. Experts believe that aliens are very likely to exist. Do aliens really exist? It is reported that there are 200 billion solar "brothers and sisters" in the Milky Way. At present, scientists have discovered 150 stars surrounded by planets, which are distant relatives of the earth. Researcher Wang Sichao made a speculation that even if one of 10 stars is surrounded by planets, then the earth should have 20 billion brothers and sisters in the Milky Way. Just as the earth is the only planet with advanced intelligent life among the nine planets in the sun, there should be 65438+ 10,000-150,000 planets suitable for the development of life, and then intelligent life will be generated and scientific and technological civilization will be formed. Their level should be the same as that of the earth or. Even if aliens really exist, many scientists now point out that the vast planets are far away from each other and it is impossible for aliens to visit the earth. Wang Sichao, on the other hand, thinks that, just as people in banpo village couldn't imagine the development of human science and technology today six years ago, it's only been more than one hundred years since the Wright brothers invented the plane and now the spacecraft shelled the comet, and aliens may have more advanced technology to visit the earth. However, Wang Sichao also said that at present, scientists have no conclusive evidence of the existence of aliens and have not captured the radio signals of aliens. Twenty years ago, a UFO was suspected to be an alien plane. 197 1, Gaoyou saw a UFO and provided an eyewitness report. Since then, Wang Sichao has been studying spiral and fan-shaped UFOs in China. He told reporters that this kind of UFO appeared 16 times in China, among which19,81was witnessed by many people on July 24th, and was seen in China 15 provinces and cities, which is probably the most witnessed UFO incident in the world. Researcher Wang Sichao received more than 70 witness reports and studied them for more than 20 years. Eyewitness reports show that the UFO appeared at 10: 33 -52 that night, and began to appear over the junction of southern Inner Mongolia and northern Shaanxi, showing an arc-shaped light belt, moving slowly westward like a nebula, with a strong flash in the center of the light belt. When the UFO moved over Yongchang, Gansu, it hovered for half a minute, and its shape became an ear shape. The outer ear is crescent-shaped, one bright and one dark, and it turns out of the spiral light band and continues to the west. Subsequent observation in guanxian, Sichuan Province showed that the whole spiral gradually changed from the brightest yellow in the center to light blue. Finally, researchers at Qinghai Station of Purple Mountain Observatory observed that the elevation angle of UFOs at about 30 degrees in the northwest suddenly disappeared by itself. According to the research and calculation of researcher Wang Sichao, the flying height of the UFO is about 650km, the moving speed is1.6km/s, and the rotation period of the central luminous body is 1 1 s. Seen from the south, the UFO center rotates counterclockwise. "July 24th" UFO may be related to extraterrestrial intelligent life. Experts have different views on this UFO phenomenon. Some experts think it may be a meteor or a comet, but Wang Sichao believes that comets and meteors move much faster in astronomical observation; Another way of saying this is that the third-stage rocket propulsion fell off and spilled excess fuel during the rocket launch. Wang Sichao thinks that this speculation can't be established either, because rockets are usually launched from west to east by using the rotation of the earth, and 15 of China 16 UFO appearances are from east to west, and this time is no exception. Moreover, rocket propulsion cannot hover in the air, and there is no rocket launch record corresponding to the time when UFOs appear. Wang Sichao said that his research for more than 20 years has basically ruled out the possibility that this UF0 is an aircraft launched by human beings, and this time UF0 can have high maneuverability at an altitude of 650 kilometers, especially the strange hovering, indicating that it may be a special spacecraft related to extraterrestrial intelligent life.
