In 2019, the astronomical research team in mainland China used the "China Sky Eye" to detect a pulsar from 3 billion light-years away, and since then, the "China Sky Eye" has received signals from this pulsar almost every day, and these signals have regular waveforms and frequencies, and have been repeated 1,652 times in 47 days.
When the "China Sky Eye" team released these data, there was a global discussion about these signals, some of them thought that these signals could be "greetings" from extraterrestrial civilizations, while others thought that it was normal to have such signals.
Although these signals may be from extraterrestrial civilizations, there are various explanations, such as fast radio bursts, a pulsar that has just exploded, or an abandoned artificial satellite.
Because these signals come from the depths of the universe 3 billion light-years away, it is also very difficult to study these signals, but when these signals are thought to be extraterrestrial civilizations, people's curiosity is also aroused, so what choice should humans make in the face of these signals?
1. The "Chinese Sky Eye" received an extraterrestrial signal.
In April 2019, researchers at Hopkins University used the Green Fort radio telescope in the United States to observe a pulsar in space, called FRB121102, a pulsar 3 billion light-years away from Earth.
The biggest feature of this pulsar is that its signal is very bright, and the signal is not timed, so its signal will continue to flicker, and at the same time, this pulsar will burst out a large number of signals in a short period of time, and then it will send out the signal again after a long time.
In April, a team of researchers from the United States made an observation of the pulsar, but they found no signals, but just a month later, the pulsar suddenly burst out with a large number of signals, and these signals continued to be emitted for about a week, after which the pulsar never sent a signal again.
When these signals were discovered by the American scientific research team, they immediately observed the pulsar, recorded the data of the burst signal, and then uploaded the data to the database of the international astronomical community for researchers around the world to study.
However, after the data was uploaded to the database, the Chinese astronomical research team found the data and further analyzed the data, and finally found that the waveform and frequency of these signals have a certain pattern, and this pattern has been repeated 1652 times in 47 days, which makes the "China Sky Eye" team very curious about these signals, so they used the "China Sky Eye" to observe the pulsar.
When the "China Sky Eye" completed their observations, they found that these signals were all from the pulsar, and the waveform and frequency of these signals were regular, so they finally uploaded the data for researchers around the world to study.
But when the scientific teams in other countries analyzed these signals, they found that the pattern of these signals did not originate from the pulsar, but from other signal sources, which were in the vicinity of the pulsar.
When the team of "China Sky Eye" analyzed these signals again, they found that the frequency and waveform of these signals were very obvious, so they extracted the waveforms and frequencies of these signals, and conducted an in-depth analysis of the waveforms and frequencies of these signals, and finally they found that the waveforms and frequencies of these signals are very regular, which is a very complex waveform, and the frequency of these signals is also very low. Therefore, the waveform and frequency of these signals are not due to man-made interfering signals.
Therefore, when the "Chinese Sky Eye" conducted further research on these signals, they believed that these signals may come from an extraterrestrial civilization 3 billion light-years away, and these signals may be the "greetings" sent by the extraterrestrial civilization to humans, so these signals are also considered to be the most likely signals of extraterrestrial civilizations ever discovered by mankind.
2. "Extraterrestrial civilizations are not to be trusted".
Some people think that it is very normal to have such a signal, it is likely to be a new pulsar, and the characteristic of this pulsar is that it will continue to send out signals, so this may be some problems with the observation instruments on the earth, while others believe that these signals are very likely to be signals from extraterrestrial civilizations.
But these signals were eventually considered to be signals from extraterrestrial civilizations, and they also caused many people to worry, because they were worried that if these signals really came from extraterrestrial civilizations, then these extraterrestrial civilizations were likely to want to invade the earth, or raze everything on the earth, so they called for these signals to be replied to, and to convey the peace wishes of mankind to the extraterrestrial civilizations.
Others believe that it is very dangerous to have such signals, and the Chinese astronomical research team has not found any evidence of extraterrestrial civilizations after studying these signals, so they think that these signals are still more likely, so they believe that humans should not reply to these signals until there is evidence to prove the source of these signals.
One of the most well-known is Stephen Hawking, who once conducted research on extraterrestrial civilizations when he was alive, and put forward many views about extraterrestrial civilizations when he was alive, and in 2016, Stephen Hawking conducted research on extraterrestrial civilizations in a paper, and discussed whether humans should respond to the signals of extraterrestrial civilizations in the paper.
Stephen Hawking believes that although human beings have a very strong desire to explore extraterrestrial civilizations, human beings should remain silent, because human beings have no evidence for the existence of extraterrestrial civilizations, and they also do not know the attitude of extraterrestrial civilizations, and whether the technology of extraterrestrial civilizations is more advanced than humans, so if human beings reply to the signals of extraterrestrial civilizations, it may cause a devastating disaster, so human beings should not interact with extraterrestrial civilizations.
Stephen Hawking believes that if alien civilizations have the ability to go to Earth, then their technology will definitely be much more advanced than humans, and may even invade species on Earth, or destroy everything on Earth, so if humans declare the existence of extraterrestrial civilizations, then this is likely to cause a devastating disaster.
3. "Keeping silent" is the greatest protection for human civilization.
The exploration and interaction of human beings with extraterrestrial civilizations is indeed a topic of great interest to human beings, because if alien civilizations really exist, then their technology will definitely be very advanced, and may even be of great help to human technology, so it can be said that the existence of extraterrestrial civilizations may bring a revolution to the development of human science and technology.
However, human exploration and interaction with extraterrestrial civilizations is also very dangerous, because the attitude of extraterrestrial civilizations and the thoughts of human beings may be very different, so human beings should respect and respect extraterrestrial civilizations, and should not interfere with extraterrestrial civilizations, nor should they reply to extraterrestrial civilizations, because if they do so, they will expose the location of human beings, and at the same time, it may also trigger alien civilizations to invade human beings.
Therefore, in the process of exploring and discovering extraterrestrial civilizations, human beings need to be very cautious, and the impact of the existence of extraterrestrial civilizations on human civilization is also very complex, and the existence of extraterrestrial civilizations may have an extremely far-reaching impact on human beliefs, morals, culture and other aspects, so human beings need to be psychologically prepared and culturally adapted to extraterrestrial civilizations.
But human exploration of extraterrestrial civilizations is also very important, because whether extraterrestrial civilizations exist in the end, and whether extraterrestrial civilizations are more advanced than human beings, are very important to human beings, but in the process of exploring extraterrestrial civilizations, human beings may also have a contact with extraterrestrial civilizations, so human beings need to make some preparations for extraterrestrial contact events.
Human beings may need to establish international protocols and norms to deal with the potential dangers brought about by the arrival of extraterrestrial civilizations, and at the same time, it is also necessary to develop some instruments that can conduct research on extraterrestrial civilizations in order to understand the existence of extraterrestrial civilizations as much as possible.
epilogue
These unknown signals from 3 billion light-years away are indeed a huge mystery to mankind, and although the source of these signals has not yet been confirmed, the study of these signals is also very interesting.
However, human exploration and interaction with extraterrestrial civilizations may have an extremely far-reaching impact on human civilization, so human beings need to be psychologically prepared and culturally adapted to extraterrestrial civilizations, and at the same time, they also need to respect and revere extraterrestrial civilizations, and should not interfere with extraterrestrial civilizations.
