Is UFO real or fake?

On September 26th, 2000, from 197 18: 58 to 19: 07, Ji Xiang of Huaisi Commune in Hanjiang County in the north of Yangzhou and Tao Siyan of stonebridge in the south of Yangzhou independently and surprisingly observed a strange astronomical phenomenon. A full moon-sized spiral luminous body appeared in the northwest night sky, still hanging. Since then, Wang Sichao, a researcher at Nanjing Purple Mountain Observatory of Chinese Academy of Sciences, has been insisting on UFO exploration for more than 30 years. On July 20th this year, the first UFO scientific exploration forum in China will be held in Shanghai. Recently, the reporter interviewed Professor Wang Sichao, one of the organizers. Millions of people witnessed two UFOs, namely 1 kloc-0 from 22: 33 to 52 on July 24th, 1995/981and from 22: 00 to 25: 00 on July 26th. More than ten provinces and cities in China witnessed these two large-scale UFO incidents, "almost half of China", with millions of witnesses including the Purple Mountain Observatory. Professor Wang said that the Purple Mountain Observatory collected more than 70 and 50 witness reports respectively, and then conducted further scientific investigation on some witnesses. Most of these eyewitness reports are authentic and can be mutually verified. 198/kloc-0 On the night of July 24, 2008, spiral UFOs flew over southern Xinjiang from the border area between southern Inner Mongolia Autonomous Region and northern Shaanxi, with a flight distance of about 2,000 kilometers. Professor Wang Sichao described, "First of all, I saw a faint luminous object in the night sky, shaped like a cloud, drifting westward. Over Yongchang, Gansu, it turned into a crescent shape, which looked like an ear at close range. Hanging in mid-air suddenly turned around and slowly raised his tail, which felt very strange. " Professor Wang said that the crescent-shaped light flickered with the rotation, especially when it was bright, and at the same time it turned out of the spiral light belt and flew west. This time, the spiral UFO slowly moved westward, getting bigger and bigger, which was surprising. "It is ten times or twenty times larger than the diameter of the full moon, which is very spectacular." "At that time, we collected many reports, and many witnesses drew beautiful pictures. It can be said that paintings painted in different places can confirm each other. " It looks like light from one angle and mosquito-repellent incense from another. UFO is much smaller than expected. For the above two UFO incidents, Professor Wang Sichao selected 38 and 26 high-quality UFO reports from a large number of eyewitness reports and scientific investigation records, and analyzed and calculated the physical parameters such as flying height and speed of these two UFOs. 198 1 year, the flying height of spiral UFO is about 650km, and the moving speed in the second half is about1.6km/s.1on July 26th, 1995, the flying height of fan-shaped UFO is about1460km, and the flying speed is only 0.29km/s. Professor Wang explained that there are many high-level astronomy enthusiasts in China, and some eyewitness reports were observed by astronomy enthusiasts. "They like to watch constellations since childhood, and there are strange phenomena. After observation, they marked UFOs in the constellation position. We can calculate the altitude and flight direction through the spherical astronomical method, according to the situation he painted, and through the longitude and geographical latitude. " Professor Wang said with a smile, this is a bit like the triangle between junior high school and senior high school. Although the earth is a sphere and the calculation process is difficult, it can be calculated by scientific methods. How big is the UFO? "It is much smaller than you think." Professor Wang Sichao speculates that it may be only a few square meters, but what we see may be several hundred square meters. "Just like a person smoking, the cigarette can turn very big, but the cigarette end is very small." Many of them are actually "flying animals". After years of research, Professor Wang Sichao divided UFOs into more than ten kinds, five of which can be explained by known natural or man-made phenomena, including fireball UFOs, spotted UFOs, bright stars, flying sticks and flying sticks. 1February 997 15 At about 1 1: 30, in the southwest of Shandong Province, some residents saw a fireball slowly flying from the east in the middle of the night, with a big tail, and then it became a big fireball "dragging" two or three small fireballs, accompanied by a strong explosion. Finally, it is clear that a meteorite landed, but in the mouth of local residents, it became a "UFO." "Another time was at 200 1. At that time, a Nanjing resident wrote to me. It was July and it was very hot. He likes the cool air on the top floor. When he saw some glowing dots flying in the sky, he quickly drew up and painted things from north to south. Later, I saw it again, and it was also a luminous point. He was very strange and confused, so he wrote to us. I said it has appeared twice. You put the telescope beside you. If it appears for the third time, you point to it. It was the third time that a bird flew like a herringbone. Most bright stars are caused by birds flying over the town at night and reflecting light. " As for flying sticks photographed many times at home and abroad, there is a UFO researcher in Beijing. He made up his mind to catch the flying stick and catch it with a net. Later, it was found to be a moth, but when the camera was shooting, the speed was different, and there was a delay effect, so it became a stick. Therefore, we must be cautious in UFO research. "We generally choose UFO research, and at least observe a few more points to get some reliable data." How UFOs Overcome Gravity Professor Wang Sichao said that there are currently seven kinds of UFOs that are still difficult to be explained by known natural or man-made phenomena. This includes spiral, fan-shaped, light-spherical, spherical lightning, grotesque cars in the air, flying saucers and hovering spindle-shaped UFOs, among which spiral, fan-shaped and light-spherical UFOs may be related to extraterrestrial intelligent life aircraft. "Judging from the basic characteristics of two UFOs, 198 1 and 1995, this may be a special spacecraft. It ejects a lot of fine particles and gas substances when flying, and when it rotates, it forms a spiral UFO. " Professor Wang Sichao explained that at 1995, they calculated that the altitude was 1460 kilometers and the speed was 0.29 kilometers per second, plus or minus 0.05; 198 1, the altitude is calculated to be 654 kilometers, and the speed is also calculated to be 1.6 kilometers per second. These two times can be said to be very slow! ""According to the truth, such a low speed will fall in space. Why Shenzhou 5 spacecraft can't turn down in the air? It's because it's very fast. "Professor Wang pointed out that this kind of aircraft may have strange anti-gravity characteristics. Professor Wang said that the matter that humans can see and the dark matter that is hard to see are all dominated by gravity. Helicopters can only hover in the troposphere with a height of less than 10 kilometers, where the air is dense. When the helicopter's propeller rotates, it sprays air downward. The downward jet gives the helicopter a reaction force to balance it with gravity (gravity of the earth), so that the helicopter can hover in the air. The two UFOs flew in the space of 650 km and 1460 km from the ground, respectively, where the atmosphere was very thin, and the observation showed that they didn't spray material downward. In this case, it is difficult for them to hover or fly at a very low speed without falling. Therefore, this kind of aircraft may have the peculiar characteristics of anti-gravity. " Man has not mastered the high technology of anti-gravity. So I think they may be special spacecraft related to extraterrestrial intelligent life. "The research stagnated only because it was so rare. China's research on UFOs began with the discovery of UFOs by Harold in the United States on June 24th. 1947. Although the research on UFOs has passed 60 years, it is still in the "primary stage", mainly because UFOs are so rare. Professor Wang Sichao said that at present, the research on UFO in China has mainly reached qualitative and semi-quantitative analysis. Professor Wang told reporters that in the past, the research on UFOs generally stayed in the "qualitative" judgment. " For a phenomenon, estimate what the situation is and judge whether it is in the past. Such qualitative judgment is not enough according to the present science, and there must be quantitative analysis. "Professor Wang said that for a long time in the past, China's research on UFOs stayed on the qualitative judgment of data. Because UFOs are very rare, it is not enough to rely on a few observations. Experts made a quantitative analysis of two UFO sightings, 198 1 and 1995, because the eyewitness reports were sufficiently accurate. They selected witness reports from dozens of different locations and calculated the height and height error through spheres and triangles. " Through quantitative analysis, important parameters can be obtained for the latest research. "Professor Wang said that after experts from Nanjing Purple Mountain Observatory published the calculation method, raw data and quantitative sighting report of 1995, scientists from other regions could investigate whether this was the case at that time according to the original report published by them. In addition, Professor Wang Sichao said that at present, China has begun to make new attempts in observation methods. In the past, it was difficult to observe UFOs. They come and go without a trace. When you open the telescope, they disappear. However, now we can use new methods to shoot directly with some digital cameras with higher pixels.
