According to foreign media reports, according to foreign media reports, China built the world's largest 500-meter spherical telescope (FAST) in the karst mountains of Guizhou Province, one of which is to receive Information on extraterrestrial civilization.
A few days ago, the "Atlantic Monthly" senior deputy editor Ross Anderson visited here and had an in-depth exchange with the famous Chinese science fiction writer Liu Cixin to discuss different views on the dark forest rule.
In January last year, the Chinese Academy of Sciences invited Liu Xixin, a splendid science fiction writer from China, to visit the latest national-level spherical radio telescope in the southwest region. This giant telescope is currently the world’s largest radio telescope, and its width is almost twice that of the telescope in Puerto Rico, the Arecibo Observatory. The accuracy of this Big Mac is so high that it can be detected by a spy satellite even if it does not transmit signals externally. But it is mainly for scientific research, but also has an extraordinary role: the first device on Earth to monitor the signal of alien civilization. This means that if the information of alien intelligent organisms comes from space in the next decade, China will probably hear it first.
From this point of view, it is not surprising that Liu Cixin was invited to visit this radio telescope. He has a very strong appeal for exploring the universe in China. The National Space Administration of China sometimes invites him to participate in various scientific investigations. Liu Cixin is a well-deserved leader in the field of science fiction in China. Many Chinese science fiction writers are accustomed to calling it "Liu Liu." In the past few years, engineers at the National Astronomical Observatory of the Chinese Academy of Sciences have been telling Liu Cixin about the progress of the construction of this large-scale radio telescope. It also shows how Liu Cixin is inspiring their work.

But I have to say that inviting Liu Cixin to visit this device is also a strange choice. In his book there is a lot about the risk of contact with alien civilization. He warned that "the emergence of other intelligent species" may be coming soon and may lead to the extermination of human beings. In a book's postscript, he wrote: "Maybe after ten thousand years, the sky staring at humanity will remain silent. But maybe when we wake up from sleep again, we will see that the earth's orbit is hovering like Moon-sized alien spacecraft."
In recent years, Liu Cixin has ranked among the world's leading writers. In 2015, his science fiction "Three-body" won the Hugo Award for Best Long Story. Barack Obama once told the New York Times that the first of the three-body trilogy brought him a new kind of cosmology during his presidency. Liu Cixin also told me that Obama’s staff had asked him to provide a sample of the third book.
At the end of the second part, a protagonist in the book described the core idea of ​​the trilogy. He said that no civilization should declare its existence to the universe. When other civilizations in the Universe realize that this civilization exists, they will be regarded as a potential threat. All the Universe civilizations will eliminate the competitors until they encounter a highly skilled competitor who will eliminate them. This cruel view of the universe is called the "dark forest rule" because it imagines every civilization in the universe as a hunter hidden in the dark forest and listens to the voices of potential opponents.
The episode of Liu Cixin's Trilogy trilogy began in the late 1960s when a young Chinese woman sent messages to nearby galaxies. The civilization that received the information began a centuries-long plan to enter the Earth, but the woman did not care about the survival of human beings. The particles emitted by the alien civilization disrupted the Earth's particle accelerator and prevented any development in basic physics. The world's development speed has been greatly slowed down.
Science fiction is sometimes called future literature, but historical allegories are still one of its main models. Isaac Asimov's "Base" is based on classical Romans, and Frank Herbert's "Sand Dune" borrows from the history of Bedouin Arabs. However, Liu Cixin is not willing to associate his book with reality. He also told me that his creation was inspired and influenced by the history of the earth civilization, especially the "more advanced technology civilization and the aboriginal encounter." Such encounters often occurred in the 19th century, when China in Asia remained closed, but with the arrival of the European sea empire, once the great heavenly state no longer exists.
This summer, I went to China to visit this newly completed observatory. Before I visited Beijing, I met with Liu Cixin. I chatted endlessly with him about the adaptation of the "Three Body" into a movie. “People want it to be the Chinese version of Star Wars,†he said, looking helpless. The shooting of the film has already ended in mid-2015 and is still in post-production. The entire effects team was even replaced during this period. "When it comes to making science fiction movies, our system is not mature enough," said Liu Cixin.
I used the object of Liu Cixin as the most important thinker in China in contact with the alien civilization, but I also want to know what will happen when I visit the new radio telescope. After the translator conveyed my question, Mr. Liu stopped smoking and laughed.
He said: "It looks like it is beyond the scope of science fiction."
A week later, I took the high-speed rail from Shanghai and headed south along an elevated railroad. I saw the high-rise buildings on both sides of the building obscure and receded. Each city's mega-buildings were filled with countless windows. From 2011 to 2013, the amount of cement concrete poured in China was greater than that of the United States throughout the 20th century. China has already started building railways in Africa and hopes that the domestic high-speed railways can be extended to Europe and even reach North America through the Bering Strait tunnel.

As the train headed inland, skyscrapers and cranes began to dwindle. The train shuttles between the verdant rice fields and the low mist. It is easy to think of ancient China. At that time, China spread the word to all parts of Asia; brought metal coins, banknotes, and gunpowder into human life; and built river trunks that are still irrigating terraces. When all the way to the west, the hills near the railway are getting steeper and steeper, and the hills are getting higher and higher until I have to lean against the windows to see the whole mountain. Every once in a while, Hans Zimmer’s bass scores and the station stop sounds. When the two trains met, the windows were full of dazzling white light, and the glass buzzed with the buzzing sound of the train at high speeds.
At noon, the train arrived at Guiyang Railway Station. This is the capital of Guizhou Province, one of the poorest and most remote provinces in China. Guiyang High Speed ​​Rail Station is a flashy sponge-like building. The social transformation driven by the government seems to be under way. The sign of persuading smoking inside the station can be seen everywhere. The speakers repeatedly remind passengers to “maintain good atmosphereâ€. When an elderly man suddenly plugged into the railway, a security guard pulled him in front of hundreds of people.
The next morning, I walked through the hotel lobby and saw the driver who took me to the Observatory. The entire journey lasted for four hours. After two hours of driving, he got off the rain and walked to farmland thirty meters away. An old woman was harvesting rice in the fields. The driver asked her about the direction of the observatory 100 kilometers away. Because of the lack of language, after the two sides repeatedly communicated intermittently, the old woman took her scythe in one direction.
We set off again, passing through a small village, more than a motorcycle and pedestrians by the roadside. The eaves of some buildings along the road have been upturned for centuries; others are new, and the residents have been relocated here from the Observatory.
