From ancient times to the present, human beings have never stopped wanting to explore the universe! The continent already had an understanding of the stars of the universe about 20,000 years ago, with the green dragon in the east, the white tiger in the west, and the Xuanwu in the north...... It is said that the later Hetuluo book, innate gossip, "Lianshan", "Burial" and "Zhou Yi" are all related......
In the journey of human exploration of the universe, every unconventional signal is full of mystery and temptation. Recently, China's large radio telescope, Sky Eye, picked up a strong signal from 1.3 billion light-years away, which was repeated 1,863 times in 54 days. This phenomenon has sparked a lot of attention and discussion, the most notable of which is: Should we respond to this signal?
According to reports, this signal has extremely high intensity and frequency repeatability, suggesting that it may be derived from some highly developed civilization technology. The repetition and regularity of the signals hint at the intelligent life forms that may exist behind them. This assumption is based on the fact that, on the scale of the universe, the probability of natural phenomena producing such regular signals is extremely low.
It has been said that when considering whether to respond to this signal, we must first assess the potential risks. Renowned scientist Stephen Hawking has warned that contact with extraterrestrial civilizations could be similar to the scenario of Columbus's arrival in the Americas, which could be a disaster for humans on Earth. If the technological level of extraterrestrial civilizations far exceeds that of Earth, then they may have the ability to pose a serious threat to us. Moreover, even if they do not harbor malicious intent, the mere way and content of communication can cause confusion to human society.
There are also many points in favor of replying. First, contact with extraterrestrial intelligent life would be a giant leap forward in the history of human civilization and could lead to revolutionary advances in our science, technology, and culture. Second, if we do receive signals from extraterrestrial civilizations, then it is likely that we have been observed that the window of communication has opened whether we reply or not. Finally, by replying, we can demonstrate humanity's desire for peace and friendship, and the presence of our intelligent life.
If we decide to reply, we have to be cautious. First and foremost, any response should be discussed and agreed upon at the international level to ensure that the common voice of all humanity is represented. Second, the content of the reply should be demilitarized and low-tech, avoiding revealing too much information about our location, technical capabilities, and defensive weaknesses. In addition, the means of recovery should also take into account security considerations and avoid the use of technologies that could be exploited to target the planet.
Whether or not to reply to this strong signal from 1.3 billion light-years away is not only a matter of science and technology, but also a choice of the future destiny of mankind. Any decision should be based on a thorough assessment of risk, as well as an awe of the unknown. Whatever the outcome, this step will be a big step in the history of human civilization, and let us look forward to this day, and at the same time we must be fully prepared for it.
