The term “Hard Science Fiction” refers to any story where the science used is more than just a futuristic setting or a MacGuffin for the characters to chase after. Larry Niven’s Ringworld and Scott Westerfeld’s The Risen Empire are two examples of this genre; the reader has to be able to grasp at least a little bit of concepts like man-made worlds or artificial intelligence in order to keep up. The way technology in these stories affects the main characters, or an entire civilization, is essential to the plot.
In Cixin Liu’s newly-translated masterpiece The Three-Body Problem, the story begins in the Chinese Cultural Revolution and ends in the present day with humanity’s realization that a war with an alien species scheduled to start in four centuries may already be lost. It’s hard science fiction, and the science that the reader is expected to understand is theoretical physics. Brace yourselves, this one gets really deep.
