 Why did Yang Liwei carry a gun? Science and Technology Daily: Dont talk about aliens in everything.


Vision China

Astronomers have released details of a radio telescope in Canada that receives mysterious signals from distant galaxies, according to a report in the British weekly Nature. Many self-Media use sensational headlines to link the incident with aliens. In fact, the so-called mysterious signal is a fast radio burst, which has nothing to do with aliens.

Humans may have been lonely for too long, eager to find their own kind in the universe, so from time to time they will catch the wind and look for some evidence of the existence of aliens. So what are the rumors about aliens these years?

Rumors

Hawking said that aliens were no longer human beings.

The late British physicist Hawking did often mention aliens, and even participated in the search for aliens. Introducing the Breakthrough Listening project launched in 2016, he said: The older I get, the more I believe in extraterrestrial life. After a lifetime of curiosity, I began to help a global project to find evidence. The Breakthrough Listening team hopes to use radio and optical technology to search for extraterrestrial intelligent life on a large scale throughout the galaxy and its 100 nearby galaxies, trying to find signs of extraterrestrial life.

However, Hawkings claim that aliens are no longer human originates from the misunderstanding or distortion of Hawkings intention in some media. The idea originated in 2010, when some media claimed that Hawking believed that aliens might have evolved into energy bodies.

The plot of pure energy body in science fiction does not accord with Hawkings view on life. There is an article entitled Life in the Universe written on Hawkings official website in 1996, in which Hawking clearly put forward his understanding of life: There must be a mechanism to absorb energy from the outside world and turn it into energy available to him. Such a life form is not at all an energy body because it is not in essence divorced from the entity of matter.

Rumor two

The Stargate of the Gulf of Aden is open to alien attack

In November 2010, several earthquakes occurred successively in the Gulf of Aden. The incident has been highly valued by governments and scientists have been sent to investigate the site of the incident. It was rumored that there was a Stargate in the Gulf of Aden, which was a gateway connecting the rest of the universe. Others further explained that the Stargate is a wormhole. Wormhole is a way to travel in space and time in the universe. Now the channel is open. In order to prevent aliens from coming out and invading the earth, countries sent fleets to guard there.

In response, Wang Deng, a postdoctoral student in the Department of Astronomy, Shanghai Jiaotong University, said that wormholes are narrow tunnels that may exist in the universe connecting two different regions of space and time, and they are a very peculiar four-dimensional space-time configuration. In the framework of general relativity, it is generally necessary to support this special celestial body with extremely strong gravitational field by singular substances that violate the zero-energy condition. According to the theoretical hypothesis, it is possible for matter to travel instantaneously in space or time through wormholes. However, up to now, no evidence of wormholes has been observed. All the speculations about the existence, nature and space-time travel of wormholes are only theoretical hypotheses. The Stargate in the Gulf of Aden is just a series of earthquakes caused by simple geological reasons. There is no need to connect with aliens at all. Wang Deng said.

Theoretical physics also believes that, in order to form wormholes that can pass through a person or a spaceship, theoretically, a strange substance with negative mass is needed; or a cosmic string that is as strong as a black hole in length, but smaller than an atom in gravity; or a black hole with a radius of more than one light-year. The wormholes formed by too small black holes are disturbed by the material passing through them and shut down quickly. It takes at least this scale of black holes to form wormholes that can withstand human-size energy disturbances.

Unfortunately, the first two concepts exist only in theory, and do not exist naturally in the universe. And finally, to form a black hole with a radius of more than 1 light-year, it would take at least 10 billion Earth or 10 trillion Sun to hit it. And the black hole is much bigger than the entire solar system. How could it exist in the small waters of the Gulf of Aden? Therefore, although wormholes can be formed theoretically for space travel, the necessary conditions themselves can not be realized. Therefore, the saying that the Star Gate of the Gulf of Aden is wide open is untenable in scientific principle.

Rumor three

FBI Decrypted Documents Confirming the Existence of Aliens

Every once in a while, there is a rumor circulating online that the Federal Bureau of Investigation (FBI) has recently disclosed a number of confidential documents, one of which confirms the real existence of aliens.

In April 2011, several Western media reported that the FBI had declassified alien files. In fact, the FBI just put more than 2,000 decrypted materials on the official website to provide browsing and downloading. Most of them are about anti-terrorism, crime investigation and so on. Only a few articles are related to FBIs investigation of aliens and UFOs, especially one of the Guy Horter Report has become the focus of media attention.

What exactly does this report say? It is understood that the report was a memorandum sent to his supervisor by Guy Horter, the FBI staff member in charge of Washington, D.C., on March 22, 1950, which said: An Air Force investigator said that three so-called flying saucers were found in New Mexico. The flying saucer is described as a circular, central bulge with a diameter of about 50 feet. Each flying saucer is driven by three humanoid creatures only three feet tall and wearing metal tights.

The reason why this event has attracted much attention is because of its time and place. In July 1947, the famous Roswell Incident took place in Roswell, New Mexico. A flying object crashed into a local farmland and was taken over and cleaned up by the military. The military then announced that evidence of the existence of aliens had been found. But only a few hours later, the new person in charge of the matter changed his name to say that it was only meteorological balloons that crashed, and there were no UFOs or aliens. It became an important source of conspiracy theory. Many people use it as evidence for the government to cover up the truth and secretly study aliens.

So what is the truth? IBTimes (International Business Daily) article pointed out that this Guy Horter Report is never a secret file, it has always been accessible. It has been analyzed before, and the conclusion is that it is actually about a fraud that happened 60 years ago in Kansas.

The first people to make up the story were two Kansas hawkers who peddled along the street a treasure detector (actually two aluminium sticks) purportedly capable of detecting treasures such as oil and gold. To show that their treasure hunters are more effective, they falsely claim that these sticks use alien technology and fabricate the above UFO story to prove it. The story went round and round and even appeared in the local newspaper in January 1950. The Air Force Investigator mentioned in Guy Horters report provided the story to Horter after reading the above newspaper, and Horter took it as a fact report to his superiors.

So far, the truth is clear. The FBI has not declassified any classified files of aliens, just put some old files on the Internet. The memo, which has been highly publicized by the media, has long been proved to be the product of an unwise deception 60 years ago. It has no value at all and has nothing to do with aliens.

Rumor four

Yang Liwei brought his gun to the sky to prevent aliens from attacking him.

Yang Liwei, Chinas first man in space. Many people are familiar with his space story. Little is known, however, that Yang Liwei was carrying a pistol when he went into space. Therefore, there are rumors that Yang Liwei brought a pistol in order to prevent alien attacks.

This is not the case. Some experts said that the reason why Yang Liwei was allowed to take a pistol into space was not to let him use it in the sky, but let him use it on the ground. Maybe someone will say: Is the earth more dangerous than the sky? According to our current understanding of space, we have not found any extraterrestrial organisms in the universe, which affect the safety of human beings. But compared with space, there are too many organisms on the ground that can threaten human beings. Considering that when Yang Liwei returns to Earth after successfully entering space, the rocket will choose to land in some remote places, where there may be various kinds of wild animals, so let him take a pistol, which can be used to prevent being attacked by wild animals when landing on Earth. If the landing position is deviated, the pistol can also be used as a signal gun, shooting into the sky to let rescuers know what position he is in, so that they can come to rescue easily.
