Last January, the Chinese Academy of Sciences invited Liu Cixin, China’s preeminent science-fiction writer, to visit its new state-of-the-art radio dish in the country’s southwest. Almost twice as wide as the dish at America’s Arecibo Observatory, in the Puerto Rican jungle, the new Chinese dish is the largest in the world, if not the universe. Though it is sensitive enough to detect spy satellites even when they’re not broadcasting, its main uses will be scientific, including an unusual one: The dish is Earth’s first flagship observatory custom-built to listen for a message from an extraterrestrial intelligence. If such a sign comes down from the heavens during the next decade, China may well hear it first.

In some ways, it’s no surprise that Liu was invited to see the dish. He has an outsize voice on cosmic affairs in China, and the government’s aerospace agency sometimes asks him to consult on science missions. Liu is the patriarch of the country’s science-fiction scene. Other Chinese writers I met attached the honorific Da, meaning “Big,” to his surname. In years past, the academy’s engineers sent Liu illustrated updates on the dish’s construction, along with notes saying how he’d inspired their work.
But in other ways Liu is a strange choice to visit the dish.
