Of course, I’ve only brought up two examples. Other universal laws of physics have been used as weapons as well, though we don’t know all of them. It… - Liu Cixin

Why not? Of the four possible sites, this has the best electromagnetic environment.” “What about the human environment? Comrades, don’t just focus on the technical side. Look at how poor this place is. The poorer a village, the craftier the people. Do you understand? If the observatory were located here, there would be trouble between the scientists and the locals. I can imagine the peasants thinking of the astronomy complex as a juicy piece of meat that they can take bites from.” This site was indeed not approved, and the reason was just what the task force leader had said.

Cheng Xin gazed up at the giant black columns reaching into space. They lifted up the domed sky and seemed to turn the universe into a Palace of Death. Is this the ultimate end for everything? In the sky, Cheng Xin could see the end of the columns. She pointed in that direction. “So the ships entered lightspeed at the end?” “That’s right. These are only about a hundred kilometers high. We’ve seen columns even shorter than these, presumably left by ships that entered lightspeed almost instantaneously.” “Are these the most advanced lightspeed ships?” “Maybe. But this is a rarely seen technique. Death lines are usually the products of Zero-Homers.” “Zero-Homers?” “They’re also called Resetters. Maybe they’re a group of intelligent individuals, or a civilization, or a group of civilizations. We don’t know exactly who they are, but we’ve confirmed their existence. The Zero-Homers want to reset the universe and return it to the Garden of Eden.” “How?” “By moving the hour hand of the clock past twelve. Take spatial dimensions as an example. It’s practically impossible to drag a universe in lower dimensions back into higher dimensions, so maybe it’s better to work forward in the other direction. If the universe can be lowered into zero dimensions and then beyond, the clock might be reset and everything returned to the beginning. The universe might possess ten macroscopic dimensions again.

Those two axioms are solid enough from a sociological perspective … but you rattled them off so quickly, like you’d already worked them out,” Luo Ji said, a little surprised. “I’ve been thinking about this for most of my life, but I’ve never spoken about it with anyone before. I don’t know why, really.… One more thing: To derive a basic picture of cosmic sociology from these two axioms, you need two other important concepts: chains of suspicion, and the technological explosion.” “Interesting terms. Can you explain them?” Ye Wenjie glanced at her watch. “There’s no time. But you’re clever enough to figure them out. Use those two axioms as a starting point for your discipline, and you might end up becoming the Euclid of cosmic sociology.” “I’m no Euclid. But I’ll remember what you said and give it a whirl. I might come to you for guidance, though.” “I’m afraid there won’t be that opportunity.… In that case, you might as well just forget I said anything. Either way, I’ve fulfilled my duty. Well, Xiao Luo, I’ve got to go.” “Take care, Professor.” Ye Wenjie went off through the twilight to her final meet-up.
