Cixin Liu - The Dark Forest

Luo Ji continued on ahead, but realized that he didn’t know where he was going. He stopped, found Hines and Jonathan in the crowd, and walked over to them.

“So what should I do now?” he asked when he reached them.

“You’re a Wallfacer, so of course you can do anything within the scope of the Wallfacer Act,” Hines said to him with a bow. “Although the act still has restrictions, you can now mobilize practically all of the resources of Earth International.”

“That includes the Fleet International’s resources, too,” Jonathan added.

Luo Ji thought for a moment, and said, “I don’t need to tap any resources right now. But if I’ve really recovered the power granted by the Wallfacer Act…”

“There’s no doubt about that,” Hines said. Jonathan nodded.

“Then I’ll make two requests. First, order will be restored in all cities, and normal life will resume. There’s no mystery about this request. I’m sure you understand.”

Everyone nodded. Someone said, “The world is listening, oh god.”

“Yes, the world is listening,” Hines said. “Restoring stability will require time, but because of you we have faith that it can be done.” His words were echoed in the crowd.

“Second: Everyone, go home. Leave this place in peace. Thank you!”

The people were silent after hearing this, but soon began to buzz as his words were passed back through the crowd. The crowd began to disperse, slowly and unwillingly at first, but eventually the pace picked up and car after car headed off down the road in the direction of the city. The many people walking along the roadside looked like a long glowing colony of ants in the night.

Then the desert was empty once again. Only Luo Ji, Shi Qiang, Hines, and Jonathan were left on the sand littered with chaotic footprints.

“I am truly ashamed of my former self,” Hines said. “Human civilization has a history of just five thousand years, yet we cherish life and freedom so highly. There must be civilizations in the universe with a history of billions of years. What sort of morality do they possess? Is there any point to that question?”

“I’m ashamed for myself, too. The past few days, I’ve even begun to doubt God,” Jonathan said. When he saw Hines about to cut in, he raised his hand to stop him. “No, friend. We might be talking about the same thing.”

They embraced, tears streaming down their faces.

“So, gentlemen,” Luo Ji said as he patted them on the back. “You can go back. If I need you, I’ll get in touch. Thank you.”

He watched them go off, supporting each other like a happy pair of lovers. Now he and Shi Qiang were the only ones left.

“Da Shi, anything you’d like to say now?” he said, turning to Shi Qiang with a smile.

Shi Qiang stood rooted to the spot, as stunned as if he had just witnessed a thrilling magic trick. “My boy, I’m damn confused.”

“What? You don’t believe I’m an angel of justice?”

“You’d have to beat me to death before I’d say that.”

“And a spokesperson of a superior civilization?”

“A little better than an angel, but I don’t believe that either, to tell you the truth. I’ve never thought that was the case.”

“Don’t you believe in fairness and justice in the universe?”

“I don’t know.”

“But you’re in law enforcement.”

“I said I don’t know. I’m genuinely confused.”

“Then you’re the most sober one here.”

“So can you tell me about the justice of the universe?”

“Very well. Come with me.” Then Luo Ji walked straight out into the desert, with Shi Qiang following close behind him. They walked a long while in silence, then crossed the highway.

“Where are we going?” Shi Qiang asked.

“To the darkest place.”

They crossed the highway to where the embankment blocked out the lights of the residential area. Groping about in the dark that surrounded them, Luo Ji and Shi Qiang sat down on the sandy ground.

“Let’s begin,” Luo Ji’s voice sounded in the dark.

“Give me the easy version. At my level, I’m not going to understand anything complicated.”

“Everyone can understand, Da Shi. The truth is simple. It’s the kind of thing that, once you hear it, you’ll wonder why you didn’t come up with it yourself. Do you know about mathematical axioms?”

“I took geometry in high school. ‘Only one straight line can be drawn between two points.’ That kind of thing.”

“Right. So now we’re going to set out two axioms for cosmic civilization. First, survival is the primary need of civilization. Second, civilization continuously grows and expands, but the total matter in the universe remains constant.”

“And then?”

“That’s it.”

“What can you derive from those little things?”

“The same way you can figure out an entire case from a bullet or a drop of blood, cosmic sociology is able to describe a complete picture of galactic and cosmic civilization from those two axioms. That’s what science is like, Da Shi. The cornerstone of every discipline is quite simple.”

“So let’s see you derive something.”

“First, let’s talk about the Battle of Darkness. Would you believe me if I said that Starship Earth was a microcosm of cosmic civilization?”

“No. Starship Earth lacked resources like parts and fuel, but the universe doesn’t. It’s too big.”

“You’re wrong. The universe is big, but life is bigger! That’s what the second axiom means. The amount of matter in the universe remains constant, but life grows exponentially. Exponentials are the devils of mathematics. If there’s a microscopic bacterium in the ocean that divides once every half hour, its descendants will fill the entire ocean in the space of a few days, so long as there are sufficient nutrients. Don’t let humanity and Trisolaris give you a false impression. These two civilizations are tiny, but they are only in their infancy. Once a civilization passes a certain technological threshold, the expansion of life through the universe is frightening. For instance, take humanity’s present navigation speed. In a million years, Earth civilization could fill the galaxy. And a million years is a short time measured against the universe.”

“So you’re saying that, taking the long view, the entire universe might have that kind of… what are they calling it, a ‘dead hand’?”

“No need for the long view. Right now the entire universe has been dealt that dead hand. Like Hines said, civilization may have started in the universe billions of years ago. Looking at the signs, the universe might be packed full already. Who knows how much empty space there is in the Milky Way or the universe, or how many resources are left?”

“But that’s not right, is it? The universe looks empty. We haven’t seen any other alien life apart from Trisolaris, right?”

“That’s what we’ll talk about next. Give me a cigarette.” Luo Ji groped about in the dark for a while before taking the cigarette from Shi Qiang’s hand. When Luo Ji next spoke, Shi Qiang realized he had moved to a spot three or four meters away. “We need to increase the distance to make it feel more like outer space,” Luo Ji said. Then he lit the cigarette by twisting its filter, and Shi Qiang lit one of his own. In the dark, two tiny red planets stood in distant opposition.

“Okay. To illustrate the problem, we now need to establish the most elementary model of cosmic civilization. These two balls of flame represent two civilized planets. The universe is made up of only these two planets, and apart from them there’s nothing else. Erase all of our surroundings. Can you locate that feeling?”
