Recently, a file decryption enthusiast in the United States purchased a deposit from the Central Intelligence Agency (CIA) Decrypted UFO file on CD , And uploaded the files to The Black Vault website for public browsing and downloading. The 2700-page archive is exciting for some flying saucer enthusiasts, but can these files really help scientists find aliens?

Misunderstood UFO
In 2012, the Kentucky State Police received a large number of unidentified flying objects (UFO) sighting reports. It was discovered that a shiny mysterious white object appeared in the sky. The local government department could not give an exact explanation, so there were rumors in the local area: “Aliens” had arrived in Kentucky.

Actually, This white mysterious object does not come from a distant planet, but is an ongoing test project of the Internet company Google . They released a number of large balloons in an attempt to build a high-speed wireless internet network in the air and set up an information highway for remote areas to solve the problem of poor mobile phone signal and internet speed.
UFO has always been a topic often mentioned in “unsolved mysteries” book stalls, and occasionally became news in the newspapers. When people find objects in the air that cannot be explained by previous experience, they will be regarded as UFOs, and sometimes they will use their imagination to associate UFOs with possible life outside the earth. however, For most UFO incident reports, what witnesses saw were actually known objects or phenomena It is only due to visual errors, or the phenomenon itself is beyond the scope of the observer’s knowledge, that the UFO’s misjudgment is formed.
In addition to the Google balloon over Kentucky, a wide variety of objects and phenomena have been misjudged as UFOs:
In 1995, over Manchester, England, two Boeing 737 pilots noticed some shiny objects sliding quickly above them. The captain described this object as a fast-flying Christmas tree composed of many shining points. The first officer claimed that it saw a black wedge-shaped object. At that time, the air traffic controller did not find any flying objects within the detection range of the radar, so the incident was classified as a UFO incident. However, by comparing a similar sighting in 1990, analysts believe that what the two pilots observed was actually an obsolete satellite crashing into the earth. The bright light came from the interaction between the satellite and the atmosphere.

Coincidentally, in 1976, two police officers in Devonshire, England, also regarded Venus as a UFO and sounded their siren in an attempt to chase and arrest “aliens.” An American couple also reported that they were being chased by a UFO and claimed to be able to see the window on the UFO with a telescope. However, the UFO position they said was actually the position of Jupiter, and the reason why Jupiter chased them was probably because the visual effect of “the moon walked and I walked” gave them an illusion.
Why are scientists right
Not interested in UFO research?
Whenever a strange sight appears in the sky, the most excited people are probably the scientists. The unknown situation in the sky may be related to the atmosphere, space, astronomy and other disciplines. Whether it is out of curiosity to explore the unknown or the actual need to do research and publish papers, scientists will never let go of any opportunity to discover new things.
However, as early as the 1960s, the scientific community had already formed a consensus- UFO research will not bring scientific breakthroughs .
In the 1950s and 1960s, big news of UFO appeared in the United States every three to five. The U.S. Air Force initiated the Blue Book Project and conducted a systematic study of various UFO reports in an attempt to find possible explanations and reasons. However, due to organizational deviations, this plan has attracted criticism from politicians, journalists, and scholars from all walks of life, who believe that the quality of the research planned to be carried out is low, and there seems to be some acts of covering up information. The thankless U.S. Air Force originally wanted to suspend the plan, but worried that this would lead to more accusations about covering up information, so it decided to delegate the relevant research work to a committee composed of university scholars. After several screenings, Professor Edward Condon of the University of Colorado was finally determined to be the head of the committee, so people are accustomed to calling this committee “the Condon committee.”

After studying a large amount of materials, the committee formed a report with a length of about a thousand pages, entitled “Scientific Research of UFO”, also called “Condon Report. The report analyzed 117 UFO incidents and their causes, and concluded: Further UFO research may not bring scientific progress . However, the “Condon Report” did not completely deny UFO research. It also pointed out that subjects such as atmospheric science and radio propagation may benefit from further exploration of some UFO phenomena.
But this is not to say that aliens have come to the earth and created new phenomena in the atmosphere and radio propagation, but some phenomena that occur in the atmosphere and the ionosphere that affect the propagation of radio waves, which may be mistaken for UFOs. For example, there is a lightning phenomenon called “red elves” in the middle and upper atmosphere. The relatively large-scale “red elves” can extend from 30 kilometers above the ground to 95 kilometers above the ground, and can also be horizontally Extending about 30 kilometers, it looks like a huge “jellyfish” or flying saucer in the sky. This phenomenon, which may be regarded as a UFO, was not recorded for the first time until 1989, and it has become a phenomenon of great interest to scientists. The “Fortune II” satellite developed by my country’s Taiwan region has also carried out observations of this phenomenon from space.
Regarding whether the UFO is an alien spacecraft, the “Condon Report” report argues that ” This is the most unlikely explanation “.

How to find aliens scientifically?
Denying the connection between UFOs and aliens does not mean that scientists are not interested in finding life in the vast sky. Like our country’s radio telescope, FAST, it sets the search for extraterrestrial civilization as one of its scientific goals.
After the use of radio transmission signals, people naturally think that since radio signals can cross the ocean and send information to remote places, it is possible for aliens to use radio signals to spread civilization information to other places in the universe. In 1924, when the distance between Mars and the Earth became relatively close, the United States launched the “National Radio Silence Day” from August 21 to August 23. All radio stations were silent for 5 minutes per hour to listen to the Martians. The signal provides a “quiet” environment. At the same time, the U.S. Naval Observatory used an airship to send a radio antenna to an altitude of about three kilometers, where it conducted signal monitoring.Of course, through detection, we now know The Martians only exist in our imagination, so this much fanfare exploration also ended in nothing. .

When radio astronomy was born at the beginning of the last century, radio astronomers quickly realized that these radio telescopes could not only hear and capture natural signals from astrophysics processes, but also may capture artificial signals emitted by extraterrestrial civilizations.
In 1960, astronomer Drake of Cornell University proposed the concept of a “water hole”. He believes that if other civilizations have the same way of forming life forms as ours, they will naturally have a special liking for “water”. Water is composed of hydrogen and oxygen. Near 1.4GHz, there is an area between the radio spectrum composed of hydrogen and hydrogen and oxygen, which can be used to superimpose artificial signals.
Although Drake himself found nothing in his searches near several stars at that time, the concept of “water hole” profoundly affected the subsequent search of extraterrestrial civilizations. The frequency of water hole is still one of the preferred frequency bands for search.
The FAST telescope plans to take advantage of its high sensitivity to monitor the Andromeda (M31) galaxy near the water hole frequency. If there is a signal from extraterrestrial civilization among the trillion stars in the constellation M31, then FAST must be able to catch it.

If the transmitting device is installed at the back of the radio telescope, the antenna of the radio telescope can also become a signal transmitter with strong gain. Some radio telescopes have both receiving and launching capabilities, and once actively sent signals into the universe in an attempt to get in touch with aliens.
In 1974, the world’s largest radio telescope “Arecibo” sent a signal to the globular cluster M13. The image formed by this bunch of signal codes marked numbers, the elements and basic units that make up DNA, the double helix structure of human DNA, the shape of the human body, the location of planets, and the appearance of a telescope. Since then, there have been dozens of such attempts, and the content of the transmitted signal has also been varied. Among them, there are not only the use of government public funds to develop, but also private sponsorship or private spontaneous fundraising. But so far, people have not received any response from extraterrestrial civilization.

Many people worry that the act of actively transmitting signals will expose the earth to the “dark forest” in the universe. .In order to assess the risk of this behavior, scholars put forward the concept of “San Marino Scale” .
The San Marino scale is calculated as the sum of the signal strength value and the signal characteristic value. Among the signal characteristics, the one with the lowest rating (a rating of 1) is a radar signal without specific information, and the one with the highest rating (a rating of 5) is a purposeful response to them after receiving signals from extraterrestrial civilizations. . Like the special signal sent by the Arecibo telescope to one or more planets, the risk rating is 3.
Although many scientists believe that it may be a dangerous thing to actively contact with extraterrestrial civilizations, there are currently no mandatory rules and regulations that prohibit San Marino’s higher-scale signal transmission behavior, and the scientific search continues…
