About aliens! What kind of movie is this?

Although scientists believe that even if there are aliens, it is impossible to fly to the earth, but they have not denied the possibility of intelligent life in outer space.

Does extraterrestrial life exist?

UFOs exist in mysterious ways, and tens of millions of people on earth claim to have seen UFOs. Are these "witnesses" dreamers or liars? Or is there something between a lie and the truth? Is the answer a planet in space, or does it come from human worship of mystery?

The first upsurge of UFO research in the world began with the most famous "Arnold incident" in the history of UFO research. UFO is an English abbreviation, which means "UFO", also known as "UFO" or "UFO". Refers to a moving flying object or astronomical scene, which can be observed with the naked eye or monitored by radar, but human beings can't explain it at present. People who are interested in UFO not only speculate that it comes from a more advanced civilization than the earth, but also use psychological inference to explain this phenomenon from the problems that modern people may face. Descriptions of UFOs include: fast moving or hovering; Silent, erratic or growling when moving; Shapes such as plate, cigar, sphere, ring or ellipse, according to the current statistics, have reached 100 different shapes.

Records of UFOs around the world have existed since ancient times. However, on June 24th, 1947, 1947, the American press reported Arnold's UFO sighting in a large space, which made people all over the world curious and whispering in front of people, causing a sensation all over the world.

However, in the exploration of the universe, the exploration of aliens can arouse people's interest most. Although scientists believe that even if there are aliens, it is impossible to fly to the earth, but they have not denied the possibility of intelligent life in outer space.

Nebula NGC6543, nicknamed "Cat's Eye" Nebula

Recently, two scientists discovered that two planets outside the solar system may have the conditions for life, which even aroused a fever of "extraterrestrial civilization". Some scientists think that aliens certainly exist, but it is not easy to find a planet with life like Earth. If there are planets, there is not necessarily life; Life does not necessarily mean more advanced life, it requires that the position of the planet to the parent star must be just right. According to such conditions, there are only about 6.5438+0 million planets in the Milky Way. In this 654.38+million, there must be a series of conditions for the formation of life, including water, oxygen and various chemical elements. And if the aliens on those planets have a highly developed civilization, and their history of sending radio signals to the sky is much earlier than that of the earth, which has been 1 10,000 years (our earth is only 100 years old), then it is possible to count down only 250 planets. If they are evenly distributed in the Milky Way, the latest one is 4,600 light years. In the universe, there are 654.38 billion extragalactic galaxies like the Silver System.

In order to communicate with possible alien creatures, so far, human beings have carried out 50 plans to search for radio signals in outer space, all of which ended in failure, but another way for human beings to find alien civilization, that is, to directly detect outer space by using artificial spacecraft, is still in progress. During the period of 1966, U Dan, then Secretary-General of the United Nations, asked Von Keviczky, a UFO researcher, to study how to put UFOs on the agenda of the United Nations. 1978, the First Committee of the 33rd UN General Assembly adopted the deliberation draft put forward by the Grenada government, suggesting that all member countries coordinate the scientific research and adjustment of extraterrestrial life, including UFOs. 1979, the 43rd session of the United Nations General Assembly adopted a proposal to study UFOs as a worldwide topic, and pointed out in the outline of the 47th session: "The study of UFOs involving all mankind should be a part of human efforts to solve world social, economic and political problems." 1977 the first UFO international conference was held in Mexico. 1983 the second UFO conference was held in Brazil.

Right or wrong

1972 and 1973, the United States launched Pioneer 10 and 1, Voyager1and 2 to explore distant outer space. "Pioneer" 10 and 1 1 each carry a message of congratulations written on a gold-plated plate. Voyager 1 No.2 and Voyager1No.2 each carry a gold-plated record called "Voice of the Earth", which is 30.5cm long and equipped with a playback device. It records greetings in 60 languages, 1 13 coded pictures depicting the customs of the earth (including the Great Wall of Wan Li), 35 kinds of natural sounds of the earth and 27 kinds of world famous songs. Voyager spacecraft carries the voice of the earth and the message signed by US President Carter to astronauts: "This is a gift from a distant small planet. It is the epitome of our voice, science, images, music, thoughts and feelings. We are trying to keep our time alive, so that you can understand our life. We look forward to solving the problems we face one day in order to join the civilized family of the Milky Way. This "voice of the earth" is to pin our hopes, our determination and our good wishes for the distant world on this vast and awesome universe. "

Voyager 1 and Voyager 2 fly at a speed of about 500 million kilometers per year. If all goes well, they will still send the information of the universe back to earth before 20 15. After that, they will turn off all the instruments because of the exhaustion of electricity, but they will still fly silently to the depths of space outside the solar system. The last hope comes from the expectation of the unknown. If travelers 1 2 meet intelligent aliens, maybe they can understand that there are many lonely intelligent beings around a distant star, the third from the center, and they sincerely hope to find some "cosmic relatives" in the vast space.

The hypothesis about the existence of aliens

Reports about aliens often appear in newspapers. Many people claim to have seen UFOs and even aliens, and have taken various photos about UFOs. Is all this true or not? Do aliens really exist?

According to people who claimed to have seen aliens, most of the aliens they saw were humanoid creatures, with short stature, big heads, narrow mouths like cracks and tight clothes. But some people claim that the aliens they see are tall giants, robot-like monsters, hairy monsters and even beautiful naked women. For this phenomenon, some people think that these aliens come from more than one planet. Others think it is impossible for so many different kinds of aliens to visit the earth at the same time. This chaotic description just shows that the alien's statement is unfounded. Some people think that a considerable part of these are not credible, but some of them can still be proved to be true.

Others are keen to find traces left by aliens in ancient times. They believe that all kinds of unexplained prehistoric miracles, such as the circular masks of characters in the murals in the Sahara desert, the huge stone buildings in Easter Island and South America, and the pyramids, are all related to aliens. Some scholars have suggested that human beings are descendants of aliens, or that some ethnic groups in human beings (such as Maya) are descendants of aliens mating with earthlings. But these can only be used as guesses and assumptions, and most of them still lack sufficient evidence.

Carl sagan, a famous astronomer at Cornell University, once pointed out that there are almost 200 billion stars in the whole galaxy, and quite a few of them have planets. Among these planets, it is estimated that there may be as many as one million similar to the earth's environment. Since life can be produced and evolved on the earth, it is also possible to produce and evolve and show intelligent creatures on these planets. Some of them are certainly more advanced than the present human civilization. Therefore, these astronomers believe that it is entirely possible for intelligent life to appear on other planets besides the earth.

But Sagan sneered at the news that people all over the world often meet aliens. He believes that these are all adding some technologies to the so-called aliens, and most of the alien images described are human deformation. On other planets, the evolution process of life is very different. The evolution form of extraterrestrial intelligent life is likely to be completely different from that of human beings, and the science and technology it has mastered will also be completely different from that of human beings. Moreover, these planets that may produce intelligent life are thousands or tens of thousands of light-years away from the earth. Therefore, it is totally unrealistic to think that aliens visit every year or even every day.

Sagan's views can roughly represent the opinions of serious scientists. In other words, the existence of extraterrestrial intelligent life is completely possible in theory. But all kinds of news about the discovery of aliens are mostly unconvincing. But there are still some events that are considered reliable but can't be explained by the scientific community at present, and even some prehistoric miracles that can't be understood. Are they related to extraterrestrial intelligent life? All this remains a mystery.

For the existence of aliens at present, scientists have put forward various possible ideas, which are bold and now seem bizarre, but who can blame human imagination? Maybe these fantasies will become quite big one day.

Underground civilization theory

I remember reading a cartoon story, which said that the earth is a paradise for human evolution, but there is another civilized world ruled by evolutionary insects inside the earth. Finally, underground insects waged war with human beings for the right to live on the ground. It is reported that after the American satellite "Charlie 7" went to the Arctic Circle to shoot, it was found that there was a hole in the Arctic region on the negative. Is this the entrance to the interior of the earth? In addition, geophysicists generally believe that the weight of the earth is several million times that of 6 trillion tons. If the earth's interior is solid, it will weigh more, which leads to the "hole theory" Some oil explorers found large tunnels and huge underground people underground. We can imagine that the earth people are divided into surface people and inner people, and the underground people in the underground kingdom must hold high the technology higher than the surface people. In this way, as companions of surface people, it is natural for them to travel by flying saucers that surface people can't make.

Mixed housing theory

This view holds that aliens live and work among us! In some photos taken by researchers with an amazing new type of radiation camera, it is found that some people have a light green halo around their heads, which may be caused by radiation from their brains. However, when I tried to query people with aura, I found that these people disappeared completely, and there was no sign of their existence. Aliens are hiding among us. We don't know what they are going to do, but there is no evidence that aliens will hurt us.

Human ancestor theory

There is a view that human ancestors were aliens. About tens of thousands of years ago, a group of aliens with high IQ and scientific and technological knowledge came to the earth. They found that the environment of the earth is very suitable for them to live in. However, because they didn't bring enough facilities to cope with the gravity of the earth, they changed their minds and decided to create a new race-a combination of aliens and earth apes. They took the female ape as the object and tried to make it pregnant, thus producing today's human beings.

Parallel world theory

The universe we see (that is, the total galaxy) cannot be formed in the four-dimensional universe, that is to say, the world around us is not only formed in the length, width, height and time dimensions. The universe may consist of two adjacent worlds. Although there is little connection between them, they are almost transparent to each other. These two physical worlds are usually "inseparable" worlds and have little influence on each other. When these two layered worlds are formed, the interaction force to "compound" them into a whole is great, and various substances are highly mixed together, thus forming a unified world. Later, the universe expanded. At this time, the density of matter decreases and gravity weakens, thus forming two worlds that are actually independent of each other. In other words, it is entirely possible to have an invisible parallel world adjacent to us in the same time and space. To be exact, it may be similar to our world or completely different from ours. Maybe the laws of physics and chemistry are the same, but the actual situation is different. These two worlds "dominated each other" as early as 20-/kloc-0.5 billion years ago. Therefore, flying saucers may come from another world. It may be that they accidentally broke in under some special conditions, and it is more likely that they have mastered the knowledge of traveling in two worlds, and they often shuttle between the two worlds, and their scientific and technological level far exceeds our human beings.

Four-dimensional space theory

Some people think that UFOs come from the fourth dimension. The ghostly aircraft disappeared instantly, and the satellite electronic tracking system network could not be seen at all when it was turned on. It can be thought that UFO residents are playing with space-time technology. A technical means can form some local space bends, and this local curved space will expand in the space in contact with it. After completing this step, people from another space can come to our space. As mentioned in various eyewitness reports, concrete and tangible creatures suddenly appeared on the ground near UFOs, instead of running out of a door obviously. For these situations, the above statement can be regarded as an explanation.

Since the distance between celestial bodies is extremely far away, since there is little possibility of the existence of aliens, and since space navigation is difficult, why are there so many reports about UFOs and aliens in books, newspapers, magazines, TV stations, radio stations and the Internet? There were records of unidentified objects flying in the sky in ancient times. However, the UFO report that really attracted attention began in 1878 65438+ 10. A farmer in Texas, USA, saw a disc-shaped object flying in the air. At that time, the plane had not come out. This strange phenomenon caused a sensation in the society after it was published in the newspaper. More than 150 newspapers and periodicals reprinted this news, which became the earliest example of modern UFO reporting. UFO is a kind of UFO in English. Take the first letter of three words. Its abbreviation is UFO. In some books in Hong Kong and Taiwan, the pronunciation of the three letters of UFO is written directly in Chinese characters, which is called "UFO", which is mysterious.

The first UFO report appeared in1June 24, 947. According to this report, Kenneth Arnold, a civil aviation pilot, was searching for an inexplicably missing plane near Rainier Valley in Washington when he suddenly found nine disc-shaped flying objects in the air, each with a diameter of about 30 meters, jumping forward at an ultra-high speed of 2,000 kilometers per hour, just like plates floating on the water. The reporter used the word "UFO" in his report. Since then, "UFO" and "UFO" have become synonymous with UFOs.

However, the UFO is actually a visitor from the bottom of the earth, and it is the illusion of the director of the earth sunspot! ! ! Magnesium produced in the earth's sunspot A is most likely to lose two electrons in the outer layer and become positive magnesium ion Mg+, which is a silvery white metal and keeps metallic luster in the powder state. At room temperature, it slowly oxidizes with oxygen in the air, and it will gradually darken and lose its original metallic luster if it is left in the ground air for a long time. After aluminum is oxidized on the surface, an oxide film is produced, which can still maintain a certain metallic luster and will be silver in the sun. When sunspot A is close to the ground, the crustal potential changes from 0 to positive, and the positively charged metal dust is repelled from the ground fissure because of the repulsion of the same sex. Some are scattered in the atmosphere, slowly oxidized into dust, and some dust clouds are rejected to the surface. Under the action of rotating sunspot electric field, dust rotates in groups in the air. Under the action of wind, it sometimes becomes a ball, sometimes a straw hat, a plate, a cone, a cylinder, an ellipse, etc. And the viewer gave it an image name-"UFO"! ! ! ! ! ! ! !

Because of the great influence of this incident, in order to find out the truth, in April 1950, Edward R. Murrow, a famous reporter from CBS, interviewed Arnold again. In the interview, Arnold said that the report that he saw a UFO in 1947 "did not quote me correctly. The newspaper exaggerated my words ... I said that these objects were ups and downs, like, ah, I think they are 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 that I said these objects were like plates. I mean, they fly like plates. " Arnold said that he saw a series of nine objects, one of which gave off a "terrible blue flash". Arnold concluded that they were a new type of winged aircraft. At the end of the interview, Moro concluded: "The report of 1947 is a historic mistake. Mr Arnold's original description was forgotten, but' flying saucer' became a household word. "

Meteorologist MacDonald of Arizona and Heck of Northwestern University first linked UFOs with aliens. In the mid-1960s, they suggested that some flying saucers were spaceships used by aliens to visit the Earth. This view is very consistent with ordinary people's fantasy and curiosity, and immediately became a hot topic of news speculation, enduring.

For more than half a century, the media reported on UFOs more than 6,543,800 times. Now in the United States alone, there are more than 200 reports about UFOs or aliens every day, including about 654.38+00 reports about catching aliens or having direct contact with aliens. There are more in the world. These reports have very specific time, place, people and events, and many of them are accompanied by photos, recordings and interviews of witnesses. If we all believe these reports, there are too many aliens in our world. With China's gradual integration into the world family, there are more and more reports about flying saucers and aliens in China. Most books on the market are translated, compiled or rewritten by foreigners, and quite a few are "news" fabricated by foreign newspapers on April Fool's Day. Some of our writers 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 understand to aliens and explain them by aliens, it is too far from science.

In a country with free press, any "news" can be produced 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 led a serious scientific problem to a completely different road from science.

So far, there is no serious scientific research institution or serious scientist (note that it is not a "scientist" with quotation marks) in the world who claims to have discovered aliens or alien spacecraft-flying saucers.

Carl sagan, the greatest contemporary scientist, 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 cosmic biology, specifically talked about the origin of various reports about aliens and flying saucers in his famous popular science book The Devil's Haunted World. He said: "We are often entangled in the fragmented and boastful UFO (abbreviation of" UFO "in English) legends. 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 get us through this? Is it really the crashed alien spacecraft, or are those experienced swindlers cheating those fools out of their money? Is a powerful alien playing tricks on human beings, or is it someone's point of view based on human weaknesses and defects? "

On March 38, 2006+0/0, the CIA declassified 859 secret intelligence documents on a large scale for the first time. These secret documents, which span from 1947 to 199 1 year, contain various contents, but the most interesting thing is the CIA's research on UFO phenomenon from the late 1940s to the present. The research results of the CIA on UFO phenomenon for more than 50 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 short, UFO has no evidence to show its existence!

On April 22nd, 20001,The Times reported that the British UFO department, which was founded in 1953 and had 1500 members in the world at its peak, could receive up to 30 UFO sightings every week. Due to fewer and fewer clues available for investigation, it has been 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.

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 1950s.

From 65438 to 0959, Cocconi and Morrison wrote an article which was published in the famous British magazine Nature. According to their calculations, if intelligent life exists in other parts of the universe, and their scientific level is equivalent to our 1959 level. 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, a word will be spoken for thousands or hundreds of years, but after all, it is possible to communicate. The two of them also studied the optimal wavelength of interplanetary radio wave communication, which is 2 1 cm wavelength of hydrogen atom. Because hydrogen is the most abundant element in the universe, and its wavelength of 2 1 cm is also easy to be detected.

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

Humans have lived on the earth for about two or three million years. Once upon a time, human beings thought that they were the spirit of all things, the only intelligent life in the universe, and even thought that the earth was the center of the whole universe. Later, with the progress of science and technology, people's eyes were broadened, and they realized that the vastness of the universe was far beyond our imagination, and the earth was really too small, and of course it was not the center of the universe. So people imagine that the universe is so vast that there may be an intelligent creature similar to human beings-aliens on other planets. This idea has deeply attracted some people who are keen on finding aliens.

/kloc-in the 6th century, when someone observed Mars with a telescope, they found many staggered meshes, so they thought it was a "canal" dug by "Mars entering". 1935, an American radio station announced that Martians had come to earth, which caused a false alarm. And an English writer created a science fiction novel called "War on Martians", which made many vivid descriptions of Martians and even triggered the birth of a series of novels and movies about Martians.

Are there Martians or not? In the era when there were only telescopes, it was always a mystery. In the 1960s, the spacecraft finally landed on Mars, which solved the mystery that has been puzzling people all the time: Mars is much colder than the earth, its surface is covered with mud and stones, and there are often strong winds, flying sand and stones, and there are no creatures on it, and of course there are no Martians.

After this mystery was solved, astronomers further analyzed that in the solar system, no other planet except the earth has the necessary environmental conditions for biological survival. Therefore, humans on earth are the only intelligent creatures in the solar system. To find aliens, we must go beyond the solar system.

1972, the United States launched the "Pioneer 10" spacecraft and flew out of the solar system on 1987. The metal sheet on the spaceship depicts the image of human beings, the earth where human beings live and the position of the solar system (see the right). 1977, the American navigator 1 brought more information to the outside world, including a sturdy record player and a gold-plated record, which contained dozens of human languages and many musical works (including China's ancient songs). Eager for aliens to receive it.

In order to get in touch with aliens, scientists even made huge and complicated equipment, trying to send information to aliens and receive information from them. However, after many efforts, people still haven't found aliens. Some stories about seeing aliens are just legends, which are difficult to be strongly confirmed.

It is also worth mentioning that there are flying saucers. Many people have seen it. I guess it's a spaceship driven by aliens, but it's just a guess.

So, are there aliens? Scientists have analyzed that there must be many planets like the earth in the universe, and some planets similar to the earth's environment are likely to have aliens. However, as our space and communication technologies are not developed enough, we must redouble our efforts to find them.

Someone saw it from the window at Guangzhou Port Technical School 10: 45 in the evening-the dormitory was on the fifth floor, and a flying saucer flew from the sixth floor. People on both floors can testify. When I picked up my glasses, I only saw a light point (it should be a light beam) fluctuating up and down at a speed I had never seen before. It's high and far. At that time, it took less than 1 minute from hearing someone shouting to seeing it with your own eyes. When I picked up my glasses, I was just lucky enough to see them. Then in the blink of an eye, which light spot crossed the roof of the dormitory. The whole process is only 1 minute (the time I feel).
