Since the 20th century, when people look deep into the universe, they are eager to solve a mystery. ....
Whispers patronize the earth.
1947 On June 24th, an American businessman named Arnold was flying over Washington State in a small plane. Suddenly, he found a group of huge UFOs flying in the air with him at a speed of about 1000 km per hour. Arnold's eyewitness report aroused great public interest, and since then, "UFO" or "UFO" has spread rapidly.
Arnold was not the only witness at that time-in less than a month before and after his report, many people across the United States claimed to have found similar UFOs. Perhaps coincidentally, shortly after Arnold's report, in the early morning of July 1947, in the town of Roseveare, New Mexico, Latal, an early rancher, found many strange fragments and a broken behemoth scattered on the ground. Before the US military could block the news, the news of "UFO landing" had spread. Although the military later said that the curious debris was actually a damaged weather balloon, various inconsistent explanations made many people believe that it was the military that concealed the truth that the debris came from an alien-this is the famous "Roseveare incident" in the history of searching for alien civilization in this century.
Since American Arnold first reported UFOs in 1947, UFO sightings have been reported all over the world:
1in the summer of 954, the U.S. military radar repeatedly found UFOs over Washington, DC. After the air force dispatched fighter planes, UFOs quickly disappeared.
1978 1 1 One morning in June, seven technicians of Kuwait Petroleum Company found a cylindrical behemoth on the ground near a work site. Seven minutes later, the unknown monster took off smoothly and disappeared into the night sky. It is reported that four similar incidents occurred in Kuwait this month.
On the afternoon of February 22nd, 1978, 1800km/h, the pilots of the Australian Air Force discovered UFOs. At the same time, there are similar reports in many places in the South Pacific, which became a sensational news that year.
In China, UFO sightings have been reported frequently since 1970s. 1998101At noon on October 3, Han Jianwei of Kunming, Yunnan Province took a video of a UFO with a camera in the northwest suburb of the city. It is considered that this two-minute video material is also rare in the world.
According to incomplete statistics, over the past 20 years, China has collected more than 5,000 relevant witness materials and cases. So far, there have been more than 654.38 million UFO sightings in the world, and this number is increasing at an average rate of more than 3,000 per year. American scholar Redfern said in his new book "Air crash in the universe" that the British government set up a highly confidential base in the remote Welsh valley to preserve the bodies of crashed aliens. A magazine in the United States even claimed that a confidential document of the US government showed that there was still a UFO crash survivor in the hands of the relevant departments of the US government.
Up to now, scientific investigation shows that most so-called UFO reports are caused by human activities and geological, astronomical, atmospheric and bioluminescent phenomena-countless so-called UFO reports can't prove that whisperd visited our planet.
Moreover, most scientists believe that it is completely unimaginable that such a spacecraft can fly to the earth from a galaxy with dozens of light years to hundreds of light years-even if it flies at the speed of 1/5, the energy required per second is equivalent to a 6.5 million-ton atomic bomb exploding in an instant; And transporting a ton of material from the nearest galaxy to the solar system to the earth, if it moves at a speed close to the speed of light, will require energy 1000 times that of the current human consumption on the earth! Interplanetary face-to-face communication may only be realized in movies and novels. ...
According to French media reports a few years ago, scientists from the former Soviet Union and the United States are studying a mysterious radio signal from space. According to analysis, this signal was a distress signal sent by a planet 50,000 years ago.
An American astronomer who did not want to reveal his identity told the French media: "This is an amazing breakthrough. Our computer has translated the most important part of this radio signal to the effect that please instruct us to go to the fourth universe, and there will be an explosion. We are in great danger. Our position is in the Milky Way 12.
This strange message has been translated into human-readable words by experts from both countries, but they have kept it a secret.
The astronomer said, "It's very simple. Mathematically, we estimate that this is an ancient spaceship or a planet. It seems to be looking for some kind of guidance to help them out of danger. This incident is really shocking. After hard work, we have initially calculated that this information was sent at least 50,000 years ago, and it may be longer. "
Australian astronomers communicate with outer space by radio and assert that the earth is not the only planet in the universe where human beings live. These astronomers said that the alien civilization world had sent information to the earth hundreds of years ago, but the earth's radio telescope was invented only 50 years ago, and the direction was wrong.
Dr. Herbert Berkless, the head of the research project, said: "Until now, all radio telescopes in the world have been installed in the northern hemisphere, either in the United States or in Europe. They didn't listen to information from the southern hemisphere. " Is it really alien information that can only be received from the earth side?
Australia's telescope uses the most advanced space age technology, with 9 million channels, which scientists use to receive repeated high-frequency information broadcast by aliens. This information was received within a few hours after the giant antenna test. Dr. Berkless recalled: "We were surprised to hear that this series of beeps sounded like notes. We have no doubt that this is a message sent to us by an alien civilized society. "
A few days later, the radio suddenly changed its frequency. The beep was also interrupted. After a short silence, there was a deep moan. Dr. Berchris said, "This is the voice of an alien, and the language used is different from any language I have ever heard. The voice has been talking, with occasional beeps and grunts, as if clearing his throat. I can't guess what he is saying, but from his gentle tone, I think he is sending a message of peace. "
The recordings of aliens have been recorded and analyzed by experts all over the world. At the Australian receiving station, scientists work around the clock, trying to find the planet to send information.
If aliens really exist, they will communicate with each other through radio waves for the same purpose as us humans, and they will be sent to the battlefield by plane, which is also a question of love. Scientists put forward the above viewpoint; If aliens exist, then the planet inhabited by aliens is older than our earth, and the level of social development is higher than that of human beings. They can create a machine that can reproduce and replicate itself like a virus that infects an organism-an artificial intelligence machine. It is estimated that organic computers that have already used biochips will enter the 20th century, and then with the help of genetic engineering technology, various tasks will be completed at the molecular level.
Therefore, we can further assume that aliens have mastered the technology of computer self-replication, so we will appoint robots to perform tasks.
Robots start from the alien's residence and fly technical aircraft. After a long journey, it reaches a star system and stays on the planet there, looking for the trace of intelligent life and establishing a transit station. If it is not found, it will fly to a star system by plane. So step by step, and transmit the relevant information back at any time, because robots have the function of self-replication and can repair themselves, and there are no disadvantages such as physical injury and mental decline, while mice can produce new robots, which either stay in the transit station or develop planetary reconstruction aircraft.
It can be seen that when we receive information from aliens on earth, it may be these working robots that are contacting the base camp or each other.
Therefore, there are still some scientists who are positive about the possibility of the existence of aliens. But the question is, do aliens have any contact with us?
Some scientists believe that, except for some mysterious UFO incidents in the third kind of intimate contact, in general, aliens don't want to get in touch with people on earth, but they are evasive and fleeting. Why is this happening? This is mainly due to the huge technological gap between aliens and the earth, which will inevitably lead to an insurmountable gap between them. If aliens are 10 thousand years ahead of us, it is insignificant from the perspective of cosmic evolution. But how do two kinds of life with a difference of 10 thousand years between science and technology and ethics contact and contact? If people can partially understand the behavior of monkeys, but monkeys can't understand people's thinking, then there must be what biologists call "animal psychological disorder" between them.
Perhaps, aliens are observing such an ethics, not interfering with an evolving civilization and hiding themselves. In other words, aliens are just observing us, not participating. Perhaps, they will ask some questions slightly higher than our understanding, so as to stimulate human thinking.
At the beginning of this year, an international astronomical research team announced that they had discovered a planet outside the solar system for the first time, and its diameter and orbit around a star were very similar to those of the Earth-for many astronomers, this means that there may be life forms close to the Earth.
Is there any life form in the depths of the vast and deep sky? In this boundless universe, human beings are really lonely travelers. Isn't there a similar or wiser galactic companion?
Since the 20th century, when people set their eyes on the depths of the universe, they are eager to solve a mystery-
Whispering to visit the earth?
1On June 24th, 947, an American businessman named Arnold flew over Washington State in a small plane and found a group of giant UFOs soaring in the air with him at a speed of about 1000 kilometers per hour. Arnold's eyewitness report aroused strong public interest for the first time, and then "UFO" or "UFO" (abbreviation for UFO) spread rapidly.
Arnold was not the only witness at that time-in less than a month before and after him, many people all over the United States claimed to have found similar UFOs. Perhaps coincidentally, shortly after Arnold's report, that is, in the early morning of July 1947, in Roseveare, New Mexico, the early rancher Brasol found many strange fragments and a broken behemoth on the ground near his home. Before the US military could block the news, the news of "UFO landing" had spread.

Until now, it still attracts many UFO enthusiasts to gather here once a year.
Ever since Arnold, an American, first reported UFOs on 1947, there have been reports of sightings of UFOs all over the world: 1954 In the summer, the U.S. military radar repeatedly found UFOs over Washington State, DC, and after the Air Force dispatched fighter planes, UFOs quickly disappeared; 1978 1 1 One morning in June, seven technicians of Kuwait Petroleum Company found a cylindrical behemoth on the ground near a work site.

A magazine in the United States even claimed that a confidential document of the US government showed that there was still a UFO crash survivor in the hands of the relevant departments of the US government.
However, it must be pointed out that all these eyewitness reports and reports, which are close to modern myths, have aroused the creative inspiration of Hollywood writers who are good at seizing business opportunities, but they have never been officially confirmed by any country, nor have they been scientifically and carefully verified. On the contrary, up to now, scientific investigation has proved that the vast majority of so-called UFO reports are caused by human activities and geological, astronomical, atmospheric and bioluminescent phenomena-countless so-called UFO reports can not prove that there are whispers visiting our planet.
Most scientists believe that it is completely unimaginable that such a spacecraft can fly to the earth from a galaxy with dozens of light years to hundreds of light years-even if it flies at one-fifth of the speed of light, its energy per second is equivalent to 6.5 million tons of atomic bombs; And transporting 1 ton of matter from the nearest galaxy to the earth, if it moves at a speed close to the speed of light, will require more energy than the current human energy consumption on the earth in one year 1000 times! -Face-to-face communication between stars may only be realized in movies and novels.
Is human civilization on earth "mediocre"?
1952, a young student named Miller from the Department of Chemistry of the University of Chicago in the United States suddenly had an idea: since living matter is composed of various elements, various elements can produce living matter under certain conditions. He mixed methane, ammonia, hydrogen, water vapor and other primitive substances that make up the planet, and then simulated the earth's environment 4 billion years ago, such as thunderstorms and lightning. After a period of experiments, a miracle appeared: a reddish substance appeared at the bottom of the test tube-some basic substances that can breed life-amino acids, sugar and fat!
Miller's experiment seems to confirm the theory that because the material elements on the earth are essentially the same as those on distant planets, there are a large number of galaxies similar to the solar system in the universe, so no matter which galaxy on the planet has similar conditions to the earth, life will be born; According to the viewpoint of evolution, in this case, once life comes into being, it is entirely possible for it to move from low level to high level, and then to produce rationality-this is the famous "mediocrity principle" formed in the middle of this century.
197 1 year, at the relevant international conference held in the former Soviet Union, astrophysicists who firmly believed in the "mediocrity principle" concluded according to relevant theories that there are about 1 10,000 living planets in the Milky Way where the solar system is located, and the average distance between two living planets is 300 light years.
In fact, the actual process of human search for space bosom friends began in the last century. But it was not until the late 1950s, when radio telescopes and spacecraft appeared, that this kind of exploration had practical significance.
From 65438 to 0959, the National Radio Observatory of the United States began a SETL project (a project to explore extraterrestrial intelligent life) that actually lasted for more than 30 years, trying to find human companions on the distant horizon. 1993, when the government plan ended in vain because of high cost, the SETL Institute of California, with private funding, launched the Phoenix Project with the same goal and began to search for 1000 sun-like stars.
According to statistics, in the past decades, scientists have observed and searched thousands of stars around the solar system for a long time in the range of about 80 light years. The result was somewhat disappointing: no possible source of interstellar communication was found.
Thankfully, although astronomers have not found any traces of extraterrestrial civilization in the vast space, they have also found more than 65,438+000 kinds of spectral lines of organic molecules, including basic chemicals that can constitute protein and DNA. In recent years, a series of landing explorations on other planets in the solar system have also proved the existence of extraterrestrial organic molecules. In the words of researcher Nan, deputy director of the Beijing Observatory in China, "this means that the seeds of life have floated in the vast universe, and all the planets, including our earth, are running in vibrant space. Who knows if comets or meteors planted these seeds into the earth, or even molecules with the ability to replicate, and who knows if they were imported by our ancient ancestors. "
While implementing the SETL plan, another CETL plan (communication plan with extraterrestrial intelligence) is also being implemented: in 1972 and 1974, the United States launched two space probes, Pioneer 10 and Pioneer1. Each of them brought a sign of the solar system with the image of the earth person; 1974 165438+1October16 The famous arecibo radio telescope sent a powerful radio wave to distant galaxies, including symbols representing a man, a woman and a child. 1977, the United States launched two space probes, Voyager 1 and Voyager 2. After nearly 20 years of flight, Voyager 2 has now flown over Pluto on the edge of the solar system. On it, there is a set of gold-plated records called Voice of the Earth, which recorded dozens of images and sounds introducing the earth civilization. One of them expresses the desire of mankind ... We are trying to extend the time to keep up with your time. "I hope that one day after overcoming the difficulties we face, we can become a member of the galactic civilization ..."
In the vast space, who is listening to this greeting from the earth?
There is no intelligent life outside the universe?
Although exploring extraterrestrial civilization and extraterrestrial intelligent life is an exciting topic, not all celestial and space physicists hold the view of "mediocrity principle". Quite a few scientists believe that human beings are not "mediocre", at least there are not many civilized worlds in the Milky Way, and human beings on earth are likely to be lonely travelers in the universe. They think that the only result of trying to find these nonexistent goals is to waste money.
According to Bian Yulin, a researcher at the Chinese Academy of Sciences who is engaged in observational cosmology research, people who hold this view believe that the evolution of human beings on the earth is the result of a combination of various special conditions. As long as these conditions are slightly different or changed, life will be difficult to appear and civilization will be even more hopeless; According to the birth process of modern civilization on earth, if an advanced civilization began to explore outer space about 5 billion years after the formation of its protoplanet, then human beings on earth should have received a lot of information about these planetary systems. "In fact, we haven't even seen one. This probably means that there is not even a civilization around all the stars over 5.3 billion years old in the Milky Way. " Most eloquently, so far, all the practical explorations of extraterrestrial civilization and extraterrestrial intelligent life have not yielded positive results.
"Not finding evidence does not mean finding evidence that does not exist." It is reported that NASA is implementing a project costing 654.38 billion US dollars to search for extraterrestrial life in the whole galaxy. According to this plan, from the end of this century to 20 15, the United States will launch a series of detectors, observers and orbiting telescopes to search the area around the solar system for 50 to 100 light years, looking for planets similar to the earth and trying to discover extraterrestrial life.
Undoubtedly, in the 2 1 century, the debate about extraterrestrial civilization will continue. Humans may be able to draw a conclusion in the next century. Perhaps this kind of argument will last longer, and this kind of exploration will certainly last longer. ...
