Aurora (30 page)

Freya wandered the biomes as she had in her wandering years. She did not speak in the meetings she attended, or in the cafés where she had worked just a few years previously, but merely listened. She stood at the back of a room like the figurehead of a sailing ship, or sat in a corner, looking at each speaker mutely.

As she wandered, she inspected each biome with a close regard. How was it doing? she asked the inhabitants. What had it been good for, during the voyage out? Could it continue to help them to survive another 170 years of enclosure, if they decided to go back?

She found that some of the biomes that were doing the best in
ecosystem terms were in fact the least useful to the ship’s humans during a voyage. These biomes had been brought along to convey their species to the new world, to help terraform the planet they were to have established. As farms they were less useful. But it occurred to Freya that they could be altered to make them better farms. Going back to the solar system, they would not be needed as seed banks or arks.

Song’s idea was this: proceed with the inhabitation of Aurora, by introducing to it their Terran bacteria and viruses, in the hope that after a war of microbiota, Aurora would end up habitable by humans. Some of their ecologists and bacteriologists thought that might work.

The group centered on Heloise and Bao called for them to inhabit and terraform F’s second moon, the best of the remaining candidates for inhabitation in the Tau Ceti system. It was a Mars analog and had been their previous second option, and there was no reason it wouldn’t work.

Speller continued to lead those who said they should move on, that they should refuel and resupply the ship and head to the star RR Prime. They would cross interstellar space for another eighty years, and try again in that system, which in many ways looked so promising.

Or they could stay in the ship and live in it in perpetuity.

Or they could go back to the solar system.

All these ideas were discussed endlessly, in every possible iteration.

As they talked, there grew a sense among many of them that if they stayed in the Tau Ceti system, they could combine some of these options, which were not in the deepest sense mutually exclusive. They could try again on Aurora, with test inoculations of bacteria and so on, while proceeding on F’s second moon; and refurbish the ship while living on it; and inspect and explore F’s first moon.

Options, yes; just no good ones, others said. Different ways of running out the string; different ways of going extinct, after a long, fruitless struggle, trapped in chambers even smaller than the ship’s biomes.

But they could live in the biomes!

But they couldn’t live in the biomes!

Freya spoke very little in public, but in private she continued to assert that their best chance would be to resupply the ship and head back to Earth. It was the one destination they had where they knew their descendants could survive.

“But of course,” Speller said, dropping by the little café in Olympia where Freya was staying the night. “But what’s the point of that? Why did we ever leave? Why have we gone through all this, we and all our ancestors and descendants, if not to make it work here?”

Freya shook her head at her old friend and said, “They never should have left.”

They talked and talked and talked. Twenty-four biomes, ten thousand conversations. Talk talk talk. As they talked, it began to come clear to them that they had no very effective method of governance, when it came to making decisions as a group. Had humans ever had such a thing, they asked themselves, since leaving the savannah? Since congregating in cities? They could not be sure. The histories suggested maybe not.

In the ship, ever since the troubles of Year 68, the four generations that followed had been careful to work within the system established after that upheaval, always deliberating peacefully toward consensus on all important decisions. Now even the definition of consensus was contested, and they came to realize that their political system, simple as it was, had never faced a crisis. Suspended in their voyage as they had been, there had never been anything to choose, except methods of homeostasis.

Now the test was upon them, and very quickly cracks in their façade of civility began to appear. Where there is faction, there is conflict; where there is conflict, there is anger. And anger distorts judgment. So now they were getting angry with each other, and thus scared of each other. And anger and fear were not the right emotions for the situation facing them.

In the wake of the events of Year 68, the survivors had settled on a government of representative democracy, based on a constitution setting out their political first principles. The first principles were to be upheld in everything they decided to do. More than anything else, the survivors understood that they needed to behave in ways that kept a balanced flow of elements going in their closed life-support system. To do this, their population had to be capped at no more than 2,152 people. There were also population caps for all the rest of the mammals on board. Within these carrying capacities, a maximum amount of individual human autonomy was to be maintained. But this necessarily did not include the right to reproduce; nor did it include free movement around the ship, at least in terms of residency. Each biome had its own particular carrying capacities. Nor could certain jobs and functions be neglected by the totality of the group. Any number of jobs simply had to be performed, or the ship would not remain in working balance, able to support them over the long haul of interstellar solitude.

So habitation, reproduction, education, work: all expressed ecological necessities. They had to attend to these or go extinct; that was just the way it was, that was reality. Everyone was taught that in childhood. There were limits, there were needs. Every person in the ship was part of the team, integral to society, necessary to the survival of the group. Everyone was equal in that respect, and had to be treated the same as everyone else.

Only within that set of first principles, after fulfilling the
necessities, could they find and exercise what liberties were still left. Some said that what remained was trivial. But no one had any suggestions as to how to give themselves more liberties than what they had, given their constraints. Duty first.

So, now each biome’s population met in a town meeting. Anyone who wanted to speak, spoke.

This lasted for two weeks, after which a series of polls and votes were held. They polled themselves to get an accurate count on the questions at hand. Who preferred what course of action? How many for each, and how strongly did they feel about it?

Then in most biomes there was a vote for representatives, one representative for every hundred people. In most towns there was no campaigning. People voted anonymously. Those elected who also agreed to serve then spoke to their neighbors about what they should say in the general assembly. In other biomes they chose representatives by lottery, and those selected had to promise to speak for the majority opinion in their biome; or, in some, merely to do what they thought right.

These representatives then met in Costa Rica, in the town of San Jose, and discussed matters in a general conference. This was an open-ended conference, the idea being that when everyone had discussed matters thoroughly, a poll would be taken of the entire population and then the representatives would be tasked with executing the will of the majority of the people. If it turned out to be close to a split decision, which they decided meant any minority vote larger than 33 percent, then they would work on ways to ameliorate the situation by finding some kind of middle ground, if they could. Successive votes would be taken, until a supermajority of 67 percent, or hopefully more, agreed on a course of action. At that point the minority would have to accept the judgment of the majority.

That was the theory.

While trying to come to a decision, they agreed to ask the ship to relocate itself to Tau Ceti’s Planet F, and enter into orbit around F’s second moon. This was to make a reconnaissance, to judge that moon better for habitability.

As ship made this transfer, which took seven months following a Hohmann path of least energy expenditure and used 2.4 percent of ship’s remaining fuel supply, the policy discussion raged on.

Meanwhile, many biologists on board studied samples of the Auroran pathogen, which Jochi kept in a sealed room in his ferry, a room that he had turned into a clean lab, tele-operated by him. There were still those who supported Song’s idea that they could learn to live with this Auroran thing if they could understand it better. So the studying of the pathogen went on, even though they never settled on what to call it. Vector, disease, pathogen, invasive species, bug; these were all Earthly terms, and Aram for one regarded them as various kinds of category error. “The best we can do in terms of terminology,” he said, “is to call it the alien.”

That it definitely was. The individual proteinlike samples Jochi had isolated, and put into an electron microscope that was sent over to him, were so small that it was hard to understand how they could be alive. They were certainly alive in some senses of the term, since they reproduced, but it was hard to tell how, or what else they did. In this they shared qualities with viruses and their viris, prions, and RNA; but in other ways they did not seem similar to any of these entities. Processes were happening within them at nanometer scale, even picometer scale, but what was small enough for them to eat? How could they eat? Or to put it more simply, where did they get their energy? How did they grow? Why did they grow so quickly when they got inside a human?
