Is it dangerous to explore out -of -the -world civilization?

Recently, the news of "China Eye Discovery Suspicious Signals on the Earth" appeared on the hot search, which attracted attention. There is a curiosity of the Internet: Is there really existence of external civilization? Some netizens have asked questions: Is it dangerous to explore out -of -the -earth civilization?

Whether there is an extra -civilized civilization is a probability question.

The birth of life and the formation of civilization are random incidents with low probability, but when the base is large enough, accidental becomes inevitable. There are tens of billions of galaxies in the universe. There are more than 200 billion suns in the galaxy. Many star and satellites in many scholars are enough to produce many livable planets. The age of the earth is about 4.6 billion years, and the age of the universe is about 13.82 billion years. This long time is enough to bred life and civilization. Although it has not been able to confirm the existence of out -of -earth civilization and the form of extraterrestrial life, most people believe that humans will not be a lonely wisdom life in the universe.

"China Eye" is currently the largest and most sensitive radio telescope in the world. Searching for off -site civilization is one of its major scientific goals. In 2018, the "China Eye" was installed and debugged the back -end equipment specially used for outbound civilization search. It can exclude celestial and artificial signals from the vast electromagnetic signals, and screen a useful narrowband candidate signal. The news of the hot search this time is that Professor Zhang Tongjie of Beijing Normal University uses "China Sky Eye" and found several cases of technical traces from outside the earth and a candidate signal of overseas civilization.

Exploring the risk of civilization on the ground is a topic.

We must choose between actively sending and passive receiving. Many people think that contact with outgressive civilizations will bring huge risks. The encounter between humans and alien wisdom may not necessarily be beautiful, or it will become a story like the American indigenous people encounter European colonists. Active behavior of sending human information to alien civilization or the location of the earth has always been huge controversy. The science fiction "Three Body" depicts the tragedy brought about by this. However, the current "China Eye" is only passively received and analyzed various possible signals from space. The United States has repeatedly sent signals many times: for example, in 1974, the United States used the Ares Bo Telescope to aimonize the three -minute human civilization signal to the Wuxian ball -shaped star group; The number has become a "drifting bottle" after completing the detection task, and it takes many human civilized information to roam in the interstellar space.

We need to choose a choice between actively exploring and solid. There are many factors in the existence of civilization. Although active exploration may be dangerous, it is more difficult to obtain itself. For humans, the exploration of extraterritical civilization is not only part of the exploration of the universe, but also has a profound impact on the evolution of human beings and the development of science and technology. Seeking development and progress, human civilization can be from weak to strong in the vast universe.

Human imagination of external civilization is rich, but it has not been explored to the exact answer so far. From the perspective of civilization survival strategy, low -level civilizations can indeed "build high walls, accumulate grains, and slowly call kings", and do not actively expose their position in the universe to reduce the risk of being hit by high -level civilization and dimension. However, the exploration of low -level civilizations to high -level civilization is essential to exploration of the universe. The use of "China Sky Eyes" to collect signals of extraterrestrial civilization to promote human scientific and technological progress is the beauty of both and Chinese wisdom.
