Cixin Liu - The Dark Forest

“Excellent.” Zhang Beihai nodded approvingly, then turned to the formation. “From now on, we are each of us citizens of Starship Earth. This moment might be a second starting point for human civilization. There are many things we need to do, so I would ask all of you to return to your posts now.”

The two hologram formations vanished, and Natural Selection ’s formation began to disperse.

“Sir, should our four ships rendezvous?” the captain of Deep Space asked. The captains had not vanished.

Zhang Beihai shook his head firmly. “That’s not necessary. You are currently around two hundred thousand kilometers from Natural Selection, and although that’s close, a rendezvous would expend nuclear fuel. Energy is the foundation of our survival, and with what little we have, we must conserve as much as we can. We are the only humans in this part of space, so I understand your desire to gather together, but two hundred thousand kilometers is a short distance. From now on, we have to think about the long term.”

“Yes, we have to think about the long term,” Dongfang Yanxu repeated softly, her eyes still staring at the horizon as if surveying the long years ahead of them.

Zhang Beihai continued, “A citizens’ assembly must be convened immediately to set down basic issues, then the majority of the people need to be put into hibernation as soon as possible so that the ecological systems can be operated at a minimum…. Whatever transpires, the history of Starship Earth has begun.”

Zhang Beihai’s father’s eyes emerged from the beyond once again, like rays from the edge of the cosmos that penetrated everything. He felt the gaze, and in his heart he said, No, Dad. You really can’t rest. It’s not over. It’s started up again.

The next day, still keeping Earth time, Starship Earth convened its first plenary Citizens’ Assembly, held in a venue formed from the combination of five holographic subvenues. The citizens in attendance numbered around three thousand, and the remainder who were unable to leave their posts networked in.

First off, the assembly identified an urgent matter: the destination of Starship Earth’s voyage. Maintaining the current heading unchanged was passed by unanimous vote. This target was the one Zhang Beihai had set for Natural Selection, a heading in the direction of Cygnus—or, more precisely, the star NH558J2, one of the planetary systems closest to the Solar System. It had two planets, both of which were gaseous like Jupiter and not suitable for human life, but could provide supplemental nuclear fuel. It now appeared that the choice of destination had been made after considerable thought, because along a different heading, at a distance just 1.5 light-years farther than their present destination, there was another planetary system which, according to observations, contained a planet whose natural environment was similar to Earth’s. But that system had just one planet, and if it turned out to be an inhospitable world—the conditions for a hospitable world were more exacting than the rough observations from light-years away could reveal—then Starship Earth would miss the chance to refuel. After reaching NH558J2 and refueling, they could fly at even higher speeds toward their next target.

NH558J2 was eighteen light-years away from the Solar System. At their present speed, taking into account various uncertainties in the voyage, Starship Earth would reach it in two thousand years.

Two millennia. The grim number presented another clear picture of the present and the future. Even taking hibernation into account, most of the citizens of Starship Earth would never live to see their destination. Their lives would last just a small part of the twenty-century-long voyage, and even for their descendants who would reach it, NH558J2 was just a way station. No one knew what their next destination would be, much less when Starship Earth would finally reach its true, hospitable home.

In fact, Zhang Beihai had been exceptionally rational in his thinking. He clearly knew that Earth’s suitability for human life was no coincidence, much less an effect of the anthropic principle, but rather was an outcome of the long-term interaction between the biosphere and the natural environment, an outcome that would not likely be repeated on another planet around some far-flung star. His choice of NH558J2 implied another possibility: Perhaps a hospitable world would never be found, and the new human civilization would forever voyage on a starship.

But he did not make this idea explicit. It might take the next generation born on Starship Earth to truly be able to accept a starship civilization. The present generation would have to live their lives sustained by the thought of a home on an Earth-like planet.

The assembly also determined Starship Earth’s political status. It decided that the five ships would remain part of the human world forever, but under the present circumstances, it was impossible for Starship Earth to be politically subordinate to Earth or the three fleets, so it would become a totally independent country.

When this resolution was transmitted back to Solar System, the UN and the SFJC were silent for quite some time before replying. Without taking a position, they merely sent their tacit blessing.

And thus the human world was divided into three internationals: the ancient Earth International, the Fleet International of the new era, and the Starship International that was voyaging into the depths of the cosmos. The last group had just over five thousand people, but it carried with it all the hope of human civilization.

At the second meeting of the Citizens’ Assembly, they began discussing the issue of Starship Earth’s leadership structure.

When the meeting began, Zhang Beihai said, “I think it’s too early for this agenda item. We’ve got to determine the shape of society on Starship Earth before we can decide what sort of governing bodies we need.”

“You mean, we need to draft a constitution first,” Dongfang Yanxu said.

“At least the basic principles for a constitution.”

So the meeting continued along those lines. The inclination of the majority was that because Starship Earth was a highly fragile ecosystem traveling through the harsh environment of space, a disciplined society had to be established to guarantee a unified will to survive under these conditions. Someone proposed maintaining the present military system, and the idea received majority support.

“You mean a totalitarian society,” Zhang Beihai said.

“Sir, there ought to be a nicer name for it. We’re military, after all,” the captain of Blue Space said.

“I don’t think it’ll work.” Zhang Beihai shook his head decisively. “Staying alive is not enough to guarantee survival. Development is the best way to ensure survival. During our voyage, we’ll have to develop our own science and technology to expand the size of our fleet. The historical facts of the Middle Ages and the Great Ravine prove that a totalitarian system is the greatest barrier to human progress. Starship Earth requires vibrant new ideas and innovation, and this can only be accomplished through the establishment of a society that fully respects freedom and individuality.”

“Are you talking about establishing a society like the modern Earth International, sir? Starship Earth has certain intrinsic conditions,” a low-ranking officer said.

“That’s right.” Dongfang Yanxu nodded at the speaker. “Starship Earth may have few people, but it possesses a highly refined information system through which any problem can easily be put to discussion and vote by all citizens. We can establish the first truly democratic society in human history.”
