The case of aliens

Since the distance between celestial bodies is extremely far away, since the possibility of the existence of aliens is very small, and since space navigation is difficult, why are there so many reports of flying saucers and aliens in books, newspapers, magazines, TV stations, radio stations and the Internet? The flight of unknown objects in the sky has been recorded in ancient times. However, the UFO report that really attracted attention began in January 1878, when a farmer in Texas, USA, saw a disc-shaped object flying in the air while working in the field. At that time, the plane had not yet come out. After this strange phenomenon was published in the newspaper, it caused a sensation in society. More than 15 newspapers and periodicals reprinted this news, which became the earliest example of modern UFO reports. UFO is a Unidentified Flying Object in English. Take the first letter of three words to form it. Its abbreviation is UFO. In some books in Hongkong and Taiwan Province, the pronunciation of the three letters of UFO is written directly in Chinese characters, which is called "UFO", which makes it mysterious.

The first UFO report appeared on June 24th, 1947. This report said that Kenneth Arnold, a pilot of a civil aviation plane, was searching for an inexplicably missing plane near Rainier Valley, Washington, when he suddenly found nine disc-shaped flash flying objects in the air, each with a diameter of about 3 meters, jumping forward at an ultra-high speed of 2, kilometers per hour like a dish floating on the water. The reporter used the word "flying saucer" in his report. Since then, "UFO" and "UFO" have become synonymous with UFOs.

Because of the great influence of this incident, in order to find out the truth, in April 195, Edward R. Murrow, a famous CBS reporter, interviewed Arnold again. In the interview, Arnold stated that the report about his seeing UFO in 1947 "did not quote me correctly. Newspapers exaggerated my words ... I said at that time that these objects were fluctuating up and down, just like, ah, I think they were like boats drifting on the rough water. When I describe how they fly, I say that their flight is like throwing a plate on the water. Most newspapers misunderstood me and misquoted me. The newspaper said I said these objects are like plates. And I mean, they fly like plates. " Arnold said he saw a series of nine objects, one of which gave off a "terrible blue flash". Arnold concluded that they are a new type of winged aircraft. At the end of the interview, Moreau concluded: "The report in 1947 was a historic mistake. Mr. Arnold's original description was forgotten, but' flying saucer' became a household word. "

The meteorologist MacDonald of Arizona in the United States and Heck of Northwestern University in the United States first linked flying saucers with aliens. In the mid-196s, they suggested that some flying saucers were spaceships used by aliens to visit the Earth. This view is very in line with the psychology of ordinary people who love fantasy and curiosity, and immediately became a hot spot in news speculation, which has been enduring ever since.

Over the past half century, the media has reported on UFOs more than 1 million times. Now, in the United States alone, there are more than 2 reports about UFOs or aliens every day, including about 1 reports about catching aliens or having direct contact with them. There are more in the world. These reports have very specific time, place, people and events, and many of them also have photos of witnesses, audio recordings and interviews. If we all believe these reports, then there are too many aliens in our world. With the gradual integration of our country into the world family, reports on flying saucers and aliens in our country have gradually increased. Most of the books on the market are translated or compiled or rewritten by foreigners, and quite a few of them are "news" made up by foreign newspapers on April 1st, April Fool's Day. Some of our authors don't know whether they are really stupid or really want to get rich, but they sell them to us as true stories. Most scientists admit that our present civilization is still a naive civilization, and there are still many mysteries about the universe, the earth and human beings that we don't understand, which is why we still need scientific research and scientists. But if we attribute all the things we don't know and don't know to aliens and explain them by aliens, it will be too far from science.

In a country with free press, anything "news" can be made for commercial purposes. Flying saucers and aliens are often hyped as news stories. For more than half a century, they have created huge profits for various newspapers, radio stations, television stations, film producers and publishers, and at the same time, they have led a serious scientific problem to a completely different path from science.

Up to now, no serious scientific research institution or serious scientist (note that it is not a "scientist" with quotation marks) has claimed to have discovered an alien or an alien spaceship-a flying saucer.

carl sagan, the greatest contemporary scientist and popular science expert, chairman of the Planetary Science Society of the American Astronomical Society, chairman of the Planetary Research Society of the American Geophysical Society, chairman of the Planetary Society of the American Association for the Advancement of Science, and founder of cosmology, specifically talked about the origin of various reports about aliens and flying saucers in the famous popular science book The Devil's Haunted World. He said, "We are often accused of those fragmented and boastful UFOs (abbreviation of" UFO "in English). It is not difficult to understand: what can sell more newspapers and books? What can get more attention from people? What can make people feel more interesting? What can make us pass the hard time? Is it really the crashed alien spacecraft, or are those experienced swindlers cheating those fools out of their money? Is the powerful alien playing tricks on human beings, or is it someone's view based on human weakness and defects? "

on March 1th, 21, the CIA declassified 859 secret intelligence documents on a large scale for the first time. These secret documents, which spanned the period from 1947 to 1991, contain various contents, but the most interesting one is the research on UFO phenomenon by the CIA from the late 194s to the present. The research results of the CIA on UFO phenomenon for more than 5 years confirm that the UFO phenomenon in the early stage may be a conspiracy of the former Soviet government to create social chaos in the United States; The later UFO phenomenon was caused by the secret experiment of CIA top secret spy plane. In a word, UFO has no evidence to show its existence so far!

On April 22nd, 21, The Times reported that the British UFO Department, which was founded in 1953 and had 1,5 members all over the world at its peak, received at most 3 UFO sighting reports every week. Due to the decreasing number of clues available for investigation, it has been announced to be cancelled recently. On the other hand, this shows that with the improvement of public scientific and technological quality, people pay less and less attention to UFO events, and more and more people no longer associate it with aliens, but look at it more from the perspective of natural science.

VI. Scientific exploration

As a part of exploring the mysteries of the universe, scientists are also actively exploring life outside the earth and actively searching for information about whether there are aliens. This scientific exploration began as early as the 195s.

In p>1959, Coconi and Morrison wrote an article which was published in the famous British magazine Nature. The article says that according to their calculations, if there is intelligent life elsewhere in the universe, and their scientific level is equivalent to ours in 1959. Then, they should be able to receive radio signals from people on earth. Similarly, if they want to send us a radio signal, we can also receive it. Although the distance is extremely far, it takes thousands or hundreds of years to talk a word, but after all, it is possible to communicate. The two of them also studied the best wavelength for interplanetary radio wave communication, which is 21 cm wavelength of hydrogen atom. Because hydrogen is the most abundant element in the universe, and its 21 cm wavelength is also easy to detect.

This article has greatly stimulated people's enthusiasm for exploring extraterrestrial civilization and enhanced people's confidence. Because it tells us that we can communicate with each other as long as there are aliens and their technological level is similar to ours. This article is the beginning of scientific exploration of aliens.
