Death's End (The Three-Body Problem Series Book 3)

Supposing a spaceship could somehow iron flat the space behind it and decrease its curvature, the more curved space in front of it would pull it forward. This was the idea of curvature propulsion. Unlike folding space, curvature propulsion couldn’t get a spaceship to its destination instantaneously, but it would be possible to drive it asymptotical

People realized that the Deterrence Era was a strange time. On the one hand, human society had reached unprecedented heights of civilization: Human rights and democracy reigned supreme everywhere. On the other hand, the entire system existed within the shadow of a dictator.

Later, people would call a black hole formed by lowering the speed of light a “black domain.” Compared to black holes where the speed of light was unaltered, a reduced-lightspeed black hole had a much larger Schwarzschild radius.

People dug up an ancient story, Ivan Turgenev’s “Threshold,” and used it to describe her. Like the young Russian girl in that story, Cheng Xin had stepped over the threshold that no others
