What are UFOs? (astronomical)

On June 24, 1947, American entrepreneur Arnold flew his own plane over Mount Rainier in Washington State. The weather was clear at that time, and suddenly there were nine white saucer-shaped unidentified flying objects in the north, connected in a chain shape, flying at an altitude of about 3,600 meters, flying from north to south. The diameter of the object is about 20 meters, and the flying speed is as high as 2,700 kilometers per hour, which is quite amazing. Arnold said there was no way he could catch them and they could have come from outer space. Arnold called these saucer-shaped UFOs "flying saucers." After this news was released, it caused a great sensation in the United States, so June 24th was designated as UFO Memorial Day every year. These flying objects of unknown origin or other unconfirmed origins, that is, cannot be confirmed using scientific methods or natural phenomena, are called UFOs (Unidentified Flying Objects, UFOs). In fact, "UFO" refers to "spacecraft" driven by aliens. At present, humans are still skeptical about aliens, so "UFO" includes "UFO", but "UFO" does not mean "UFO".

Although before this UFO sighting incident, there have been some reports on similar saucer-shaped flying objects, but they have not been taken seriously. After this incident, various parts of the United States paid attention to such sightings, and reports of discoveries continued to come out. Therefore, in order to investigate the truth of the incident, the Air Force launched the "Blue Book Project" in 1947, which continued for twenty-two years.* **Investigated more than 12,600 sightings. About 600 of the reports could not be explained using scientific methods or natural phenomena, which are the so-called UFO incidents. The rest could be explained by known objects or phenomena. , such as airplanes, balloons, clouds, meteors, artificial satellites, birds, light reflection, balllighting and folk activities in Taiwan, China - sky lanterns, etc. This shows that 95% of UFO sightings may be misidentification or even fake.

According to the investigation report on UFOs, the phenomenon of UFOs can be summarized into six different characteristics due to different types of UFOs:

1. The average speed is extremely fast. Come and go without a trace or appear and disappear suddenly.

2. The electromagnetic force generated can break the air, and when it appears, it can move silently and without hindrance.

3. There is a strong electromagnetic field around, which will cause the car to stall, the compass to jump randomly, the radio to be interrupted, the TV to be interfered, and the power system to malfunction.

4. It will produce various bright light changes in red, orange, yellow, green, purple and other colors.

5. There is no inertial reaction, and it can move forward or backward in a continuous polyline shape at any angle.

6. It has anti-gravity and can stay in the air without power, or rise vertically quickly and disappear.

The investigation work of Project Blue Book divided all data and files into confidentiality levels and sent them to the U.S. National Archives Administration for storage. Less confidential cases have been gradually declassified and made public, but there are still some The "topsecret" files are still hidden. Among the reports submitted under Project Blue Book, hundreds of reports have not been studied, and many official reports have not been included. Even if they are included, the reports are handled inappropriately and are often tampered with. It can be seen from this that Project Blue Book may be a cover-up used by the US Air Force to reduce the public's UFO fever, and may even cover up the authorities' secret research on UFOs.

Dr. Hynek, a world-renowned authority on UFOs, served as the spokesperson for the White House Committee on UFO Hearings and the United Nations Conference on UFO-Related Phenomena, and has been a UFO research consultant for the U.S. Air Force since 1948. , reviewed all first-hand reports of UFOs and similar incidents, and he advocated the need to treat UFO incidents with caution. As a result, he did not get along well with the Air Force, and the military abandoned Project Blue Book in 1989. Dr. Fu Heling, the executive director of the association, once visited Dr. Hynek and talked freely about UFOs. Heidegger repeatedly emphasized that some UFO incidents "have something worth exploring."

Although the name flying saucer came from the United States, American officials still deny the existence of flying saucer.

In fact, there are several secret bases in the United States, such as Area 51 north of Las Vegas, which specialize in researching special technologies related to UFOs. UFOs can often be seen in this area. Especially the stealth aircraft that have been successfully developed in recent years, their technology has surpassed the field of normal military aircraft development. These technologies may come from the research results of flying saucers, because some flying saucers have this invisible characteristic.

However, some countries, such as Brazil, Puerto Rico, Grenada and other Central and South American countries, have sufficient evidence to confirm the existence of flying saucers. Before the Soviet Union was opened to the outside world, it was not possible to talk openly about UFOs. After the Soviet Union was opened to the outside world, it has caused a research boom, and some astronauts have spoken out about their experiences of frequent contact with aliens in the sky. There are frequent reports of UFO sightings in other countries. For example, UFOs have been frequently discovered in the European Alps, aircraft and ships disappeared in the Bermuda Triangle, and the unidentified phenomenon - crop circles discovered in the UK, etc., may all be related to UFOs.

If you want to talk about the history of the discovery of UFOs, the earliest official record in the world is that of Emperor Xia of the Xia Dynasty in 1914 BC:

"Ten days of discovery", recorded In "Collection of Ancient and Modern Books". The ancient myth "Hou Yi shot the sun" evolved based on this record. The "ten days" here are not the ten suns mentioned in mythology. According to UFO science, they should be ten flying objects as big as the sun that can shine together. Later, in the reign of Emperor Jie of Xia and Emperor Xin of Shang, there were also records of "three suns appearing simultaneously" and "two suns appearing simultaneously"; during the reign of Emperor Zhao of the Western Han Dynasty, it was recorded that "there were meteors as big as the moon, and all the stars were traveling westward" and so on. , these sun, moon and stars are obviously the "UFOs" known to modern people. So far, there are about a thousand UFO records in the official history of our country. There are also some calligraphy and paintings circulating in the market that also have such records. For example, the pictorial magazine "Dianshizhai Pictorial" published by Shanghai "Shenbao" in the late Qing Dynasty and the early Republic of China has an article "Red Flames Soaring in the Sky", which describes the sky in Nanjing (Jinling) one night. A ball of fire appeared, complete with pictures and text. Therefore, if you want to study the history of UFOs, you should start from the historical records in the official history of our country.

The first UFO photo in Taiwan, China, was taken at 8:25 pm on June 28, 1967, by Cai Zhanghong (brother of Director Cai Zhangxian) at the Yuanshan Observatory in Taipei. The UFO photos taken by astronomical telescopes were only released in 1996, but only two-thirds of the images were captured. Because black spots have developed over time, after computer processing, a complete picture of the UFO is presented. It can be clearly seen that the UFO is in the shape of a disc, and the lower part of the UFO is dark black and does not emit light. Therefore, the UFO below The sky was pitch black, and other parts of the UFO were pale white, and all displays were in a luminous state. The space above the UFO was gray-white, and the visible luminosity was very strong. This photo confirmed the witness reports of many citizens in Taipei City at that time, and found that UFOs emitted strong orange-red light and looked cigar-shaped from a distance. This luminous UFO, with its shape, structure, color, luminescence and other characteristics, can be confirmed to be a UFO beyond the scope of human science.

In addition, various mysterious relics such as the large ground paintings and graphics of Nazca in South America, the Egyptian pyramids, the large stone statues of Easter Island, and the pyramids of the Mayan culture may all be left behind by aliens. And in the Old Testament of the Bible and the original Buddhist scriptures, we can use modern people's perspective to understand some records of UFOs. It can be seen that alien flying saucers have often appeared on the earth from ancient times to the present.

Recently, NASA announced that evidence of single-celled organisms similar to bacteria may have existed on Mars 300 million years ago from a Martian meteorite that fell to Earth 16,000 years ago. . In addition, astronomers have also discovered the existence of at least three more planets in other galaxies. Therefore, are there highly intelligent aliens in the universe? We can discuss it from two aspects:

1. Scientists’ estimates:

In 1960, Professor of Astronomy at Moscow State University in Russia, Wilian Ananino, once said that the entire universe is about There are more than 100 million planets inhabited by intelligent and rational life forms. The American astronomer Drake studied the famous Drake Equation and calculated that the total number of planets with intelligent life in the Milky Way is about 300,000 to one million. According to the famous Astrobiology Institute of Cornell University in the United States, Dr. Shagun estimates that there should be one million planets similar to Earth-like civilizations in this galaxy.

2. Exploration of the history of the universe:

The universe has been around 15 billion years since the birth of the Big Bang, while the earth was only formed 4.6 billion years ago. Human beings only became the masters of the earth about 100,000 years ago, and the history of their intelligent civilization is only a few thousand years old. Compared with the age of the universe, it is as short as a flash of lightning. Judging from the age of the universe, of course there are other planets inhabited by cosmic intelligent people whose civilization far exceeds ours.

Since there are so many planets with civilizations similar to the earth in this galaxy, it stands to reason that there will be aliens with intelligence higher than ours. The question is, are these aliens possible to fly flying saucers to the earth? From an astronomical point of view, except for the earth, there are no signs of highly intelligent life on other planets in the solar system. The closest star to our solar system, Proxima Centauri in the constellation Centauri, is 4.3 light-years away from the Earth. According to the speed of a large space rocket, it will take 40,000 years to reach it. Within the scope of our knowledge, it is difficult for aliens to fly flying saucers to planets in other star systems in the universe and reach the earth.

The American scientific community has been conducting the "Search for Extraterrestrial Intelligence (SETI)" since the 1950s, using very large radio wave telescopes, such as the 305-meter-diameter antenna in Puerto Rico, to receive signals from the outer layer space radio waves, but so far it has not received any intelligent signals from outer space. Within the current space-time structure of the universe and the scope of scientific knowledge, it is impossible to explain the flying saucers that come and go without a trace and provide a powerful theory of flying saucers. Therefore, when the scientific community mentions flying saucers, they still ask: "Where are they?" ” This is the most troublesome question for UFO researchers at present.

To solve this problem, UFO experts studied time and space:

1. The problem of time:

According to the special theory of relativity, high-speed motion has been confirmed Objects in , their time course will be delayed. Therefore, if the flying saucer flies at a speed close to the speed of light, it will only take about six and a half years to reach the earth from the Pleiades, which is 410 light-years away; and the Andromeda star, which is 2.3 million light-years away, will only take about 15 years. You can reach the earth. If alien technology has developed flying saucers of this speed, this is one of the possible scenarios. However, when the speed a of an object reaches the speed of light, its mass m will become infinite. According to physics: f = ma, the infinite force f required to be applied to the object cannot be produced theoretically, so this The phenomenon of this time delay effect is not so obvious. Moreover, accelerating from standstill to close to the speed of light, or decelerating from close to the speed of light to stand still, requires a considerable amount of time and distance, and cannot be achieved overnight. As for the so-called back-in-time phenomenon caused by traveling through time tunnels, wormholes, super-light speed, etc., the "patriricide fallacy" will occur, that is, going back to the period when the father was a minor. If the father is killed, then the parents will The question of whether the living self can continue to survive now; it violates the axiom of physics - "causality", so it cannot be established.

2. The problem of space:

In modern physics, some scientists believe that the space of the universe may not be the three-dimensional space we know (time is fixed to one dimension) , three-dimensional space is three-dimensional space, collectively called four-dimensional space-time). These current physical theories, as well as several theories under research, all have space dimensions beyond three dimensions. For example, the "Bosonic String Theory" has twenty-six dimensions of space-time, the "Supergravity Theory" has eleven dimensions of space-time, and the "Double-Crown Theory" has five dimensions of space-time.

The other one is called "Superstring Theory", which is based on the fact that the space-time structure of the universe is nine-dimensional space and one-dimensional time, collectively called ten-dimensional space-time. It is currently the theory that attracts the most attention from scientists. Superstring theory is the latest physical theory based on the combination of "string theory" and "supersymmetry". According to the foundation of "string theory", the space-time structure of the universe is ten degrees of space and time, which is nine degrees of space plus one degree of time. Since the universe of ten degrees of time and space is not acceptable with our current level of knowledge, scientists have divided the structure of ten degrees of time and space into the four-dimensional space and time we live in and other six-dimensional spaces as small as elementary particles. Of course, we cannot see it. , so all human knowledge is limited to the scope of four dimensions of time and space, making it impossible to break through the bottleneck of science, which is a pity.

Another characteristic of superstring theory is supersymmetry. According to this characteristic, the nine-dimensional space should be overall symmetrical, and each dimensional space should have symmetry of equal weight. Therefore, the universe should still exist in nine-dimensional spaces with equal weight, that is, the universe still maintains a complete ten-dimensional space-time structure. The universe we know is a structure of three-dimensional space plus one-dimensional time, collectively called four-dimensional space-time. If we define the three-dimensional space in which we live as the space of one universe, the nine-dimensional space can be divided into three three-dimensional spaces, and time will not be divided into separate segments. Time should be regarded as the measurement of the same universality before and after an event. Standard, so the ten-dimensional space-time of the big universe has the space-time structure of the triple universe. If we use this three-dimensional space-time structure to explore some issues that currently have no scientific explanation, such as the disappearance of solar neutrinos, the source of cosmic gamma burst rays, and the amount of dark matter in the universe that is ten times more unobservable, etc. Question, of course, the origin of flying saucers can be explained as dark planets in other heavy universes, that is, planets in super-three-dimensional spaces that we cannot observe with telescopes. Aliens on their planets drive flying saucers and occasionally fly into our space. Arrive at Earth.

Based on the witness reports from people around the world, statistical research shows that the shapes drawn are divided into giants, tall people, and ordinary people according to their height from three to 50 centimeters. There are five types of dwarves, dwarves and dwarfs, and there are also three types of different appearances: dwarfs with fur all over, green-skinned people and giants with long hair. There are eight major categories, and there are nearly a hundred species. Different shapes.

At the Central and South American Cosmic Phenomena Research Conference held in Sao Paulo, Brazil, in 1970, experts announced that there were thirteen categories of flying saucers: egg-shaped, ball-shaped, saucer-shaped, circle-shaped, Cigar type, tea cup type, flying turn type, Saturn type, semicircle type, gyro type, dome type, oval type and discus type are further subdivided into one, three and two types. Among these flying saucers, there are very large space motherships that go back and forth between their planets and the earth. Because it is difficult to lift off after landing on the earth, they release small flying saucers when they reach the sky above the earth. After completing their mission, they immediately take back the small flying saucers and return home.

Since there are so many types of aliens and flying saucers, it can be seen that aliens not only come from one or a few planets, but from many different planets. If aliens have been living on the earth since ancient times, with their superb intelligence and technological civilization, today, if they have not ruled the world, they are at least the most powerful country in the world. However, this is not the case. Due to the difficulty of space transportation, not many aliens have reached the earth. From a scientific point of view, due to factors in the biological living environment, such as gravity, air composition, temperature, food supply, resistance to germs, etc., the differences between aliens and the earth may be very large, and therefore they cannot live in them for a long time. They must leave before their bodies are harmed, so only relics and deeds can be left behind.

What is the purpose of aliens driving flying saucers to the earth? There are currently six theories:

1. Promote civilization: Aliens secretly guide humans towards developing a more civilized future and promote cosmic culture. For example, ancient civilizations such as Egypt and the Maya may be aliens The legacy of civilization. In recent years, the use of the fourth kind of contact, which is to convey some new thoughts from aliens through psychics, is called New Age thought.

2. Searching for the roots of the Earth: Aliens were once Earthlings. They left when the living environment changed and they could no longer adapt, leaving behind many glorious ancient civilization relics, such as Egypt, the Mayan pyramids, and the Nazca in South America. There are huge figures on the ground, etc. Now I want to return to the earth to visit the ruins of those ancient civilizations.

3. Sightseeing travel: Aliens have extremely high living standards and very advanced technology. They can travel to all parts of the universe, and of course they will reach this beautiful blue planet in the universe that is suitable for biological survival—— Earth.

4. Surveillance and alert: Human beings are often warlike, so aliens monitor human beings' use of destructive nuclear weapons and prevent public harm, which will lead to the destruction of the earth and affect the peace of the universe.

5. Investigation of resources: Aliens have killed many livestock and even abducted humans for medical experiments. They have also long-term exploration of various resources on the earth, often taking plants, rocks and water samples to find out what is happening on their planet. Lack of information or resources.

6. Invasion and conquest: The earth is an extremely precious planet in the universe. When aliens cannot continue to live on the original planet due to the natural environment or the population is overexpanded and need to move out, they may use the earth as the target of immigration. Therefore, they secretly reconnoiter the military secrets, geographical environment and humanistic data on the earth, and make plans for future military invasion and conquest of the earth.

There are different opinions on the above six theories. From a scientific point of view, aliens spent huge resources and sailed long distances to reach the earth. They are evil and must have their own purposes. They are likely to invade and conquer the earth. Use it as a colony, or even as a settlement after wiping out human beings. Humanity must be vigilant to prevent alien invasion.
