② Misrecognition of known phenomena or objects: The factors or objects that are mistaken for UFO phenomena are celestial bodies (planets, stars, meteors, comets, etc.). ); Atmospheric phenomena (ball lightning, aurora, magic sun, Gengetsu, Elmore fire, mirage, clouds, ground light); Creatures (birds and butterflies, etc.). ); Biological factors (human eye residual image, eye defect, ocean lake plane reflection illusion, etc.). ); Optical factors (photo artifacts caused by camera internal reflection and development defects, image overlap caused by window and glasses reflection, etc.). ); Radar bait (radar secondary wave, abnormal refraction, scattering, multiple scattering, such as reflection from electrically dense layers or clouds or reflection from high temperature and high humidity areas, etc.). ), artificial instruments (aircraft lights or sunlight, re-entry satellites, rockets, balloons, military test aircraft, searchlights reflected by clouds, flares, signal flares, beacon lights, parachutes, secret weapons, etc. ).
③ Psychological phenomenon: Some people think that UFO may be a pure psychological phenomenon, which originated from the brain of an individual or a group of people. UFO phenomenon is often intertwined with people's spiritual and psychological experience, and there may be some connection between UFO phenomenon and unexplored areas of human brain.
The product of extraterrestrial civilization: Some people think that some UFOs are navigation tools made by highly civilized life on other planets.
What the eyes see may not be true, it may be a toy plane, or it may be a vague memory and more imaginative. However, you can invite an expert to have a look.
I'll tell you a few more events!
[UFO incident in Xinjiang] Tourists photographed UFO explosion.
The UFO phenomenon in Xinjiang, which caused heated discussion, occurred in September 2005. At that time, Liu and his wife in Kunming were traveling in Xinjiang when they accidentally photographed UFOs with DV.
Ms. Liu described to reporters afterwards that the bus they took was on the way from Karamay to Xingcheng, Brzin, at about 7 pm on September 19 last year. At that time, the sun was setting and the scenery outside the window was beautiful, so she took out DV to shoot.
When the bus arrived in Brzin, everyone had a meal and had a rest. Liu and other tourists get together to watch the DV she shot along the way. As a result, they were surprised to find a bright spherical luminous body in the video!
This object is only the size of a bean on the screen, but it is particularly bright and conspicuous. The bright spot with beans on the screen shows that it seems to be chasing the car. Because the car is shaking, it is also shaking up and down, flickering, getting smaller and smaller, and then suddenly accelerating.
At the end of the video, which is also the most wonderful moment, the flying light suddenly exploded like lightning and then disappeared. Seeing the sudden explosion of an unknown luminous body in the picture, the group was amazed and watched it several times.
At the beginning of 5438+February 2005, Xinhua News Agency Nanjing Branch, Jinling Evening News and other media reported almost at the same time that Wang Sichao, a researcher at Purple Mountain Observatory of Chinese Academy of Sciences and an international UFO research expert, believed that UFOs appearing over Xinjiang were basically not human masterpieces, and might be related to extraterrestrial civilization.
[Jilin UFO incident] The photographer photographed a mysterious spot.
On June 20th this year, at 65438, a wedding photographer from Changchun City, Jilin Province went to the hospital to visit his sick father. Through the window of the ward16th floor, you can see the panoramic view of the South Lake. He loves photography and decided to take a panoramic view of South Lake in winter. In order to get the best shooting effect, he set up a digital camera and pressed the shutter. 14: 29: 58. Because of the fog at that time, the photo imaging effect was not good, so he didn't continue shooting.
65438+1October 3 1 When sorting out the photos of the northeast, I was surprised to find that there was a bright spot above this photo taken in the fog, like a flying object, just above the South Lake, with a clear moving track.
Jin Fan, executive chairman of the World UFO Congress, vice president and secretary general of the World Chinese UFO Federation, and a senior expert in UFO research, said after seeing this UFO photo that the discoverer didn't know the speed of UFO movement at that time, and there was no specific data about the shape of UFO and its impact on the surrounding area, so it is not easy to draw conclusions. At the same time, because the luminous object is too small to see the real shape clearly and there are no other witnesses, it can only be tentatively named UFO.
Ufo in Xinjiang is just the reflection of window glass.
On June 2nd, 65438, "Xinjiang 9 19 UFO" seminar and networking exchange meeting was held in the conference room of the new Beijing Planetarium. The meeting was jointly organized by Beijing UFO Research Association and Yunnan UFO Friendship Association. Liu Hezhou, who filmed the video of "Xinjiang 9 19U-FO", also attended the meeting.
At the meeting, Zhou et al., Secretary-General of Beijing UFO Association, concluded that the UFO phenomenon photographed this time was actually caused by the flashing of the flash indicator of the camera in the car and the instantaneous reflection of the flash on the window glass. That is to say, when Mr. and Mrs. Liu were taking pictures of the scenery, someone behind them was taking pictures of the scenery with a camera, but they didn't notice the flash behind them. In this way, the reflection of light through the window glass was recorded in Mr. and Mrs. Liu's camera.
Jilin UFO-formed by atmospheric lens
Regarding the latest statement that UFOs were found in South Lake of Jilin Province, Chen Yue, a former member of chinese optical society and a Shanghai scholar, thought that the light spot in South Lake of Jilin Province was actually a very common phenomenon, a typical example of the formation of atmospheric lens, which was caused by phase difference. In fact, this is the case with a series of UFO phenomena recently, but because our popular science is not high, it is easy to cause a sensation in society when similar situations happen.
Chen Yue believes that what a UFO was originally still needs careful judgment. False news "spreading false information" will undoubtedly mislead the public and cause misunderstanding of UFO. The discovery of UFO should be studied with scientific attitude and method. Wang Sichao frequently published articles saying that UFOs in a certain place in China may belong to alien aircraft.
