Vortex

Chapter Thirty-two Isaac’s Story / Orrin’s Story / The Sum of All Paths

My name is Isaac Dvali, and this is what happened after the end of the world.

In the end, Vox was mine. Its people (whom I had hated) were dead (which I regretted), and there was no one left alive but Turk Findley and the impersona of Allison Pearl.

Do you blame me for hating Vox?

The people of Vox had resurrected me when all I wanted was to die. They had believed I was something more than human, when in fact I was something less. All I had ever received at their hands was pain and incomprehension.

I had been among the Hypotheticals, my captors insisted, the Hypotheticals had “touched” me; but that wasn’t true. Because the Hypotheticals (as Vox imagined them) simply didn’t exist.

My father had made me so that I could hear the Hypotheticals talking to themselves, the whispers they sent between stars and planets, and what I had learned was that the Hypotheticals were a process —an ecology, not an organism. I could have told my captors so… but it was a truth they would have rejected, and it would have changed nothing.

The Hypotheticals were already billions of years old when they first intervened in human history.

They had originated with the first sentient biological civilizations to arise in the galaxy, long before the Earth and its sun condensed from interstellar dust. Like the first shoots rising from a wheat field in the spring, those forerunner civilizations were fragile, vulnerable, and alone. None of them survived the exhaustion and ecological collapse of their host planets.

But before they died they launched fleets of self-replicating machines into interstellar space. The machines were designed to explore nearby stars and broadcast home whatever data they acquired, and they did that, patiently and faithfully, long after their creators had ceased to exist. They moved from star to star, competing for scarce heavy elements, exchanging behavioral templates and fractions of operating code, changing and evolving over time. They were, in a sense, intelligent, but they were never (and would never become) self-aware.

What had been released into the desert vacuum and starry oases of the galaxy was the inexorable logic of reproduction and natural selection. What followed was parasitism, predation, symbiosis, interdependency—chaos, complexity, life.

I hated the people of Vox—whom I could hate collectively, because they behaved collectively—for their deeply embedded limbic superstitions, and for calling me back from the indifference of death into the pain of my physical body. But I could not hate Turk Findley or the woman who had come to call herself Allison Pearl.

Turk and Allison were broken and imperfect things—like me. Like me, they had been created or summoned by the will of Vox. And, like me, they proved to be something more and less than Vox had anticipated.

I had first met Turk in the Equatorian desert, before he or I had passed through the temporal Arch. Out of ignorance or spite, and not quite by accident, Turk had once killed a man, and he had built a life on the foundation of that guilt. His best acts were acts of atonement. His failures he accepted as a kind of punishment. He craved a forgiveness he could never earn, and he was horrified when the Coryphaeus offered him that forgiveness. Accepting it would have dishonored the man Turk had killed (who was named Orrin Mather); and the people of Vox, by submerging all such feelings in their closed limbic collectivity, had made themselves monstrous in Turk’s eyes.

Allison was a different case. She was a native of Vox whose artificial persona had allowed her a rare glimpse beyond the boundaries and limitations of her life. By adopting that persona as her own, she had successfully liberated herself from the Coryphaeus. The liberation had come at the expense of her family, her friends, and her faith.

It was a bargain I understood very well.

I wanted these two people to survive. That was why I abetted their escape. Even then, I had doubted they could successfully cross the failing Arch. But I made it possible for them to live a little longer, depending on how you measure time.

For more than a millennium the Hypothetical machines had been scouring the surface of the Earth, dismantling and interpreting and remembering the ruins of the civilization we had built on the planet that gave us birth.

There was no conscious will behind this act of scavenging, no thought, no agency. It was simply behavior that had evolved over time, like photosynthesis. The devices Turk had confronted on the Antarctic plain had accumulated a rich storehouse of data. Earth’s tangible resources—rare elements that had been refined by human activity and concentrated in the wreckage of our cities—had already been extracted and transferred to orbit and beyond, where the space-faring elements of the Hypothetical ecology had feasted on them. The Hypotheticals were very nearly finished with the Earth.

But their sensors (orbital arrays of devices no bigger than grains of dust, complexly networked) had detected Vox as soon as it crossed the Arch and directed ground-based scavengers toward it. What the Voxish prophecies had imagined as an apotheosis was just a mopping-up exercise: the last berry plucked from a barren, dying bush.

The Hypotheticals arrived not long after Turk and Allison had fled, as a cloud of insect-sized disassemblers. They were sharp-toothed and efficient. They exuded complex catalysts that unzipped chemical bonds; they came through the melting walls like smoke, followed by the toxic external atmosphere. Gusts of poison blew down the corridors and walkways of Vox Core. This was a mercy, in a way—most of the citizens succumbed to asphyxiation before they could be devoured alive.

Could I have saved them?

I hated the people of Vox for compounding my suffering by resurrecting me, but I wouldn’t have wished such a fate on them. In fact I did what I could to protect them—which was nothing.

I was lucky to be able to save myself.

Of course I was protected in the most basic sense. Like Turk, I had passed through the temporal Arch. For ten thousand years I had been a memory in the archival functions of the Hypotheticals, and they had re-created me in the Equatorian desert because that was the business of the temporal Arches: to faithfully reconstruct certain information-dense structures so that the data they contained could be used to correct errors that might have crept into local systems. It was a homeostatic mechanism, nothing more.

The disassemblers wouldn’t touch my body because I had been tagged as useful. But that protection would be worthless if Vox dissolved into its component molecules. I needed to be able to exercise conscious control over what the machines were doing.

My best opportunity lay with the Coryphaeus. The processors that constituted the Coryphaeus were heavily protected. Even the nuclear detonation that had brought down the Network had not destroyed these devices, only damaged their interface with the physical world. The disassemblers would surely devour them, but not until most of Vox Core had been pulled apart. Much of my consciousness was already embedded in these processors. The same inhibitions that prevented the disassemblers from dismantling my body might extend to the Coryphaeus’s hardware, or could be made to—or so I hoped.

The Network began to fail as the citizens of Vox died in significant numbers, and I exploited that terrible opportunity. I used dormant processors to analyze the signaling protocols of the Hypothetical machines. I linked those protocols and signaling mechanisms into the deeply nested feedback cycles of the Coryphaeus, allowing me some measure of control.

And as Vox was sterilized of human life, the Coryphaeus became a chorus of one. I became the Coryphaeus.

Once I had decoded the procedural logic of the disassemblers, it became possible to feed them false recognition signals. They promptly abandoned the deconstruction of Vox Core. I used subtler and more potent instructions to reduce them to dormancy. They lost all organizing cohesion and fell from the air like dust.

But it was too late for the inhabitants, and nearly too late for the upper levels of Vox Core, which had been eroded to a skeletal framework of girders and fractured cladding. I was able to reseal the inner portions of the city and repair the relatively minor damage to the engine decks, using a combination of robotic devices and co-opted disassembler flocks. I allowed the disassemblers to dispose of all human remains, leaving nothing half consumed.

By the time I restored the city’s lights, the corridors and tiers and plains of the city were as empty as if they had never been inhabited. The air-circulation system eventually seined away any remaining dust.

But that wasn’t all I could do, I discovered.

As I waited for Turk and Allison to return—as I hoped they would—I began to explore the newly porous borderland between the Coryphaeus and the Hypotheticals. Before long I was tapping into systems larger than the Earth itself. All Hypothetical devices were interconnected, in nested hierarchies that reached from tiny disassemblers to archival machine flocks in translunar orbit, energy-mining mechanisms in the heliosphere of the sun, signal transducers in the outer solar system, transducers circling nearby stars. All these I could now perceive and influence.

I devised filters to compress this flood of information into intelligible packets, making the secrets of the Hypotheticals small enough that I could contain them. And making myself larger in the process.

My physical body began to seem redundant, and I thought about allowing it to die. But I would need it, I thought, to interact with Turk and Allison, if and when they came back. What they found here would be difficult for them to accept, and what I planned to do next would be difficult to explain.

Over the course of their multibillion-year evolution the Hypotheticals had learned to exploit a capability they had never acquired for themselves: agency.

Agency—that is, volitional action aimed at achieving conscious ends—had arisen only sporadically in the galaxy, mostly in the climax ecologies of biologically active planets orbiting hospitable stars. Species capable of agency seldom lasted longer than it took them to overload and overwhelm their planetary ecologies. They were, as the stars measure time, an unstable and ephemeral phenomenon.

But it was just such a species that had created the self-reproducing machines that were the first progenitors of the Hypotheticals. And these blooms of organic sentience were unfailingly useful: they generated unusual information; they concentrated valuable resources in their ruins; often they launched new waves of replicators, which could be harvested or absorbed into larger networks.

In time the Hypotheticals began to actively cultivate organic civilizations.

There was no agency in this, only a blind acquisitiveness. The Hypotheticals evolved in ways that maximized their exploitation of sentient organisms. Early in the history of the galaxy, an organic civilization had constructed twin Arches in order to colonize the marginally habitable planet of a neighboring star—the species suffered decline and extinction soon after, but its technology was analyzed and adopted by the Hypotheticals. In the same way the Hypotheticals had learned to extract energy from stellar cores and gravity gradients, to manipulate atomic and molecular bonds, to order and stabilize the exchange of information over distances of hundreds of light years. Eventually the Hypotheticals had developed a means of extending the useful life of such species. If a fecund mother planet was suspended inside a temporal distortion while a system of Arches was put in place—as the Earth had been suspended during the Spin—that planet’s resource base could be expanded tenfold; its organic civilization would spill into new worlds and flourish on them, cycling through epochs of decline and expansion, reliably generating new and exploitable technologies.

Such organic species remained mortal and eventually died, of course. All biological species did. But the harvest of ruins increased exponentially.

Allison and Turk arrived at Vox Core in the storms that followed the collapse of the Arch and the dismantling of the systems that had for so many years protected Earth from its ancient, dying sun.

I welcomed them back and explained what had happened. I told them I could defend them even from the destruction of this superannuated planet—I had grown that powerful, and in a very short span of time.

But they were shocked by the deaths that had taken place. For days they wandered the empty corridors of the city. The rooms they once shared had been carved away in the initial attack of the disassemblers; they could have chosen any of tens of thousands of abandoned suites and rooms in which to make a home, but Allison told me she was unnerved by everything the dead had left behind them… the unsorted possessions, the place settings abandoned on tables, the nurseries without children. The city was full of ghosts, she said.

So I built them a new residence in a forested tier deep to starboard, using the city’s fleet of robotic constructors. I chose a location far from the public corridors, accessible by footpath. The tier’s artificial sunlight was bright and convincing, its ambient temperature consistently pleasant, its average humidity low. The recycling system stirred up gentle breezes every morning and evening, and rain fell every fifth day.

They agreed to live there until they found a better home.

I believed there might be a better home for them, though not on Vox, and certainly not on Earth. But most of my attention was occupied with the business of keeping Vox Core intact in an increasingly harsh environment.

At the equator of the Earth the oceans had begun to boil. Cyclonic winds scoured the lifeless continents, and the atmosphere grew thick with superheated water vapor. Monstrous surge tides threatened to force what remained of Vox into the rocky Antarctic shelf. And it would only get worse.

I needed to manipulate very powerful Hypothetical technology, which meant extending and elaborating my control of it.

I was able to call down from orbit a small fleet of nanoscale devices—versions of the disassemblers that had first swarmed us—to encase and protect Vox Core. Scalding waves crashed over the rocky part of the island and broke against the city’s jagged towers, but the city itself remained stable, temperate, and undisturbed. Preserving this equilibrium required gigajoules of energy, drawn directly from the heart of the sun.

It was still little more than a stopgap. Before long we would need to leave the planet altogether. I believed I could accomplish that, though it would necessitate an even greater disconnection between my mortal body and my mind.

Often during this time, walking through the passageways of Vox Core, I was startled by the sight of my reflection in a glassy surface—by the reminder that I was still a collation of blood and bone and tissue, bearing the scars of my forcible reconstruction. And the subtler scars of less visible injuries.

My father had made me what I was because he had believed in the power of the Hypotheticals to liberate humanity from death. The Voxish religion had fostered a similar belief, a programmed limbic rebellion against the tyranny of the grave.

And now the stone had rolled away, revealing only the weakling prophet of a mindless god. How disappointed my father would have been!

“I can control the passage of time,” I told Turk and Allison. “Locally, I mean.”

Although they were my friends, they were afraid of me and of what I was becoming. I didn’t blame them for that.

I had come to visit them in their home in the forest. The house I had built for them was as pleasant as I had planned it to be. The trees beyond the windows were tall and graceful. The air that whispered through the portcullis smelled of living things. They asked me to sit down at their table. Allison offered me fruit from a bowl and Turk poured me a glass of water. I was too thin, Allison said. It was true that lately I had been forgetting to eat.

I told them about the world outside. The bloated sun was scouring away the Earth’s atmosphere. Before long the crust of the planet itself would begin to melt, and Vox would be afloat on a sea of molten magma.

“But you can keep us alive,” Turk said, repeating what I had told him weeks ago. “Right?”

“I believe I can, but I don’t see the point in staying here.”

“Where is there to go?”

The solar system wasn’t entirely inhospitable, despite the swollen sun. The Jovian and Saturnian moons were relatively warm and stable. Vox could have sailed indefinitely on the blue-gray seas of Europa, for instance, under an atmosphere no more toxic than Earth’s.

“Mars,” Allison said suddenly. “If you’re serious, I mean if we can really travel between planets—there’s an Arch on Mars—”

“No, not anymore.” The Hypotheticals had protected Mars as long as there was a human presence there. But the last native Martians had died centuries ago and their ruins had been thoroughly scavenged; in recent decades the Arch had been allowed to decay and collapse. (I extracted this knowledge from the Hypotheticals’ pool of data, which had become my second memory.) Mars was a closed door.

“But you’re saying Vox Core can function as a kind of spaceship,” Allison persisted. “How far can it go, how fast?”

“It can go almost any distance. But only at a very small fraction of the speed of light.”

She didn’t have to explain what she was thinking. The planets that comprised the Ring of Worlds were linked by Arches but separated by vast physical distances. Some of these distances had been calculated by astronomers even in Turk’s time. The nearest human world was more than a hundred light-years from Earth. Reaching it would take several lifetimes. “But I can modify the passage of time so that it would seem like much less. A few hundred days, subjectively.”

“But it won’t be the same Ring of Worlds when we get there,” Allison said.

“No. Thousands of years will have passed. It’s impossible to predict what you might find.”

She looked out at the forest. Beams of artificial sunlight raked through the trees like bright, vague fingers. The tier’s high ceiling was the color of cobalt. No birds or insects lived here. There was no sound but the rustling of leaves.

After a while she turned back to Turk. He nodded once. “All right,” she said. “Take us home.”

I let my physical body sleep while I defined a sphere to contain Vox Core and part of the island beneath it. That sphere constituted our border with the exterior universe. Spacetime curved around us in a complex new geometry. Vox Core soared away from the dying Earth as if it had been fired from a gun, though we didn’t feel it: I further modified the local curvature of space to create the illusion of gravity. After a few hours we had passed beyond the orbits of Uranus and Neptune.

Turk and Allison had expressed curiosity about the journey. I would have liked to show them where we were—show them directly, I mean, without mediation—but it was impossible to look at the exterior universe from inside Vox—to human eyes it would have appeared as a literally blinding cascade of blue-shifted energy, even the longest electromagnetic waves compressed to lethal potency. But I could sample that cascade at intervals and downshift it to visible wavelengths to create a series of representative images. I compiled these images and displayed them to Allison and Turk in their forest home. The result was spectacular but not soothing. The sun was a sullen ember against the darkness of space, the Earth already invisible at the edge of the heliosphere. Stars rolled past as Vox Core slowly rotated—a remnant motion I hadn’t bothered to correct. “Lonesome,” Allison remarked in a small voice.

To an outside observer we would have looked like something paradoxical: an event horizon without a black hole, a lightless bubble from which nothing escaped but a few wisps of radiation.

In fact the barrier that enclosed us was more complex than any natural event horizon. There were no words in any human vocabulary to describe how it functioned, though I told Turk, when he asked, that it was both a barrier and a conduit. Through it, I maintained my contact with the Hypotheticals. And as we counted years for seconds I began to feel the long rhythms of the galactic ecology—the voids of abandoned or dying stars, the bright World Rings (only one of which was the familiar human one) thriving under Hypothetical cultivation, the intense activity that surrounded newly formed stars and emerging biologically active planets.

But there was no soul or agency in any of this, only the mindless pulse of replication and selection, unspeakably beautiful but as empty as a desert. The ecology of the Hypotheticals would churn on inexorably until it had depleted every heavy element, exhausted every source of energy within its reach. When the last star blinked into darkness, the Hypothetical machines would mine the gravity wells of ancient singularities; when those singularities evaporated and the universe grew dark and blank… well, then, I supposed the Hypotheticals would die too. And unlike human beings, they would die without complaint. No one would mourn them, and nothing would inherit the ruins they left behind.

It became ever more difficult to remember to tend to the needs of my organic body. I lived in the quantum processors at the heart of Vox Core, and, increasingly, I lived in the cloud of Hypothetical devices that surrounded and followed us as we fell between the stars.

I allowed myself to wonder what would happen when Turk and Allison eventually left me. Where I would go. What I would become.

Allison had preserved, or perhaps inherited, her namesake’s penchant for writing. I discovered she was setting down a narrative of everything she had experienced between the Equatorian desert and the holocaust of the Vox Archipelago, the words painstakingly hand-printed on crisp white paper. When I asked her who she was writing it for, she shrugged. “I don’t know. Myself, I guess. Or maybe it’s more like a message in a bottle.”

And wasn’t that what Vox Core had become? A bottle adrift and far from shore, its glass baked green by sun and starlight, bearing messages of bone and blood?

I encouraged her to keep writing and I memorized each page she showed me: that is, I committed it to every repository of memory available to me, not just my mortal brain but the processors of the Coryphaeus and the archival clouds of the Hypothetical entities surrounding us. One day these words might be all that remained of her.

I suggested to Turk that he might write his own story, but he didn’t see the point of it. So I settled for conversation. We talked, often for hours, whenever I sent my mortal body to visit their forest home. I knew everything the Coryphaeus had once known about him, including what Turk had said to Oscar about the man he had killed, and he was able to speak freely.

“I made it my business to learn about Orrin Mather,” he said. “He was born with some kind of brain damage. He lived most of his life with an older sister in North Carolina. He got into a lot of fights, drank some, eventually left home and made his way west. He held up a few stores when he ran out of cash and put a man in the hospital once. He wasn’t a saint—far from it. But I didn’t know any of that when I did what I did. Really he was just somebody who got dealt a bad hand at birth. Other circumstances, he might have been something else.”

Which was true of all of us, of course.

I told Turk that if he wrote down what he remembered about Orrin Mather and Vox Core I would keep the words safe, along with Allison’s, as long as Vox and the Hypothetical ecology survived.

“You think that’ll make any kind of difference?”

“Not to anyone but us.”

Turk said he would think it over.

These people, Allison and Turk, were my friends. They were the only real friends I had ever had, and I was sorry I would have to leave them. I wanted something of theirs to carry with me.

The Hypothetical ecology was a forest, lush and mindless, but that didn’t mean it was uninhabited. You might say it was haunted.

I had had hints of this before. I wasn’t the first human being to access the memory of the Hypotheticals, though my case was certainly unique. The Martians had attempted such connections, sporadically, in the years before the bionormative movement suppressed all such experiments. The first human being on Earth to make the link was Jason Lawton: he had survived his own death by colonizing the computation space of the Hypotheticals—still survived there, perhaps; but his capacity to act, his agency, had been very limited. (It occurs to me that this is almost the definition of a ghost.)

And many of the nonhuman civilizations that had come before us had found their own ways into the forest.

They remained there still, long after their physical civilizations had declined and vanished. They were difficult for me to detect, since their activity was disguised to prevent the Hypothetical host networks from identifying and deleting them. They existed as clusters of operative information—virtual worlds—running inside the data-gathering protocols of the galactic ecosystem.

I sensed their presence but could discern little else about them. The content of these clusters was fractally distributed and impenetrably complex. But there was genuine agency there—not just consciousness but deliberative action that affected external systems.

So I was not alone!—though these alien virtualities were so well defended that I couldn’t contrive a way to contact them, and so ancient and inhuman that I probably wouldn’t have understood anything they might have had to say.

Most of a year had passed since our initial conversation when Turk handed me, without comment, a sheaf of papers on which he had written the history of his experiences in Vox Core. (My name is Turk Findley, it began, and this is the story of the life I lived long after everything I knew and loved was dead and gone. ) I thanked him gravely and said nothing further about it.

We were approaching one of the stars that hosted a planet in the Ring of Worlds. I decelerated Vox Core, dumping kinetic energy into this new system’s energy mines (thus raising the temperature of its sun by some imperceptible fraction of a degree), and began to ramp down the time differential between Vox and the external universe. As we passed the orbit of the star’s outermost planet I showed Turk and Allison an image I had captured: the host star, just beginning to show a discernible disc, seen past the rim of a cold gas giant orbiting far outside the habitable zone. Deep in this stellar system, but still too far away to be visible as anything but a pinprick of reflected light, was the planet its human occupants called (or had once called) Cloud Harbor (in a dozen languages, none of them English).

It was a watery world, laced with island chains where the tectonic plates of the planet’s mantle ground against one another. It had once hosted a benign and relatively peaceful human society, occupying both the available dry land and a number of artificial archipelagos. Most of Cloud Harbor’s polities had been cortical democracies, with a few settlements of radically bionormative Martians. But thousands of years had passed since then. We had to assume that any or all of this might have changed.

Allison asked me in a small voice whether I could tell anything about the planet as it was now.

In fact I had been trolling for stray signals. There had been none, or none that I could identify. But that might only mean that the resident civilization had adopted highly lossless modes of communication. Certainly the Hypotheticals were still active here. The icy planetesimals in the far reaches of the system swarmed with busily breeding machine entities.

I was with Allison and Turk as the time differential between Vox Core and the external environment counted down to 1:1. I had created a viewscreen which filled an entire wall of the largest room of their home—in effect, a window to the world beyond Vox. It had been blank. Suddenly it filled with stars.

Cloud Harbor swam into view, an amplified image; we were still light-minutes away.

“It’s beautiful,” Allison said. She had never seen a world like this from space—the people of Vox had never been very interested in space travel. But Cloud Harbor would have been beautiful even to a jaded eye. It was a swirled crescent of cobalt and turquoise, its icy white moon standing half a degree off the sunlit horizon.

“A lot like the way Earth used to be,” Turk said.

He looked at me for a response. When I didn’t speak he said, “Isaac? Are you all right?”

But I couldn’t answer.

No, I wasn’t all right. My body was numb. My mind was full of inexplicable lights and motion. I tried to stand and toppled over.

Before my senses faded I heard the wail of a distant siren—it was the old autonomic defense system built into the city’s deep infrastructure, warning of an invasion I couldn’t see.

The people of Cloud Harbor had seen us coming. The warped spacetime around our temporal bubble, bleeding energy as it decelerated into the system, had broadcast easily detected bursts of Cherenkov radiation. So they had come to meet us.

They thought we might be hostile. They knew we weren’t an ordinary Hypothetical machine—they had learned a great deal about the nature of the Hypotheticals in the centuries since Vox left Earth. As soon as we dropped our temporal barrier, they isolated Vox Core from local energy sources and infiltrated our processors with finely tuned suppressor protocols. The effect was that the Coryphaeus went to sleep. And since much of my awareness was embedded in the Coryphaeus, I promptly lost consciousness.

I was eventually able to reconstruct what followed. Spacecraft with human passengers swarmed through the disabled barriers and docked with Vox Core. Unopposed, they entered the city and tracked down Turk and Allison, who were able to explain—once linguistic difficulties had been sorted out—who they were and where they were from. They insisted that I was not dangerous and demanded that I be released from what amounted to an induced coma. The troops of Cloud Harbor declined to do that until they were certain I was harmless.

It was an inauspicious meeting, but by the time I came to myself again it had become a more or less friendly one. I woke in my mortal body, in a comfortable bed in a medical suite in Vox Core. My mental functions had been fully restored. A woman who claimed to represent “the combined polities of Cloud Harbor” entered the room, introduced herself, and apologized for the way I had been treated.

She was tall and dark-skinned. Her eyes were large and widely set. I asked her about Turk and Allison.

“They’re waiting outside,” she said. “They want to see you.”

“They’ve come a long way, looking for a home. Do you have one to offer them?”

She smiled. “I believe we can make them welcome. If you’re curious about our world, I’ve made public records from every polity available to your external memory. Judge for yourself what kind of people we are.”

I accessed the records in an eyeblink and was reasonably satisfied, though I didn’t tell her so.

She said, “You’ve come a great distance yourself, Isaac Dvali. We can make a place for you, too.”

“Thank you,” I said, “but no.”

She frowned. “You’re a unique individual.”

“Too unique to leave this city.” I repeated what she already knew, that I shared too much of my consciousness with the processors of the Coryphaeus to allow me to leave—my body would be little more than a drooling piece of meat if it was extracted from Vox Core.

“We can address that problem,” she said confidently.

Humanity had learned a few things about the nature of the Hypotheticals, she explained. The polities of Cloud Harbor had already begun to establish virtual colonies inside the computational space of the local Hypothetical networks. Colonists were generally the elderly and infirm, who were eager to leave their physical bodies behind—I could do the same, she said.

“I’m happy enough here.”

“Alone?”

“Alone, yes.”

“Do you understand what you’re sentencing yourself to? Solitary confinement—for eternity, or until your sense of self erodes and becomes chaotic.”

“I can take precautions against that.”

I could tell she didn’t believe me. “What do you mean to do, then? Tumble through the galaxy until the end of time?”

Like a bottle on the sea.

“Long ago,” I said, “my father owned a library of books. One of the authors I read there was a man named Rabelais. When he learned he was dying, Rabelais said, Je m’en vais chercher un grand peut-être. It means, I go to seek a great perhaps. ”

“But all he found was death.”

I smiled. “Peut-être.”

She smiled in return, though I think she felt sorry for me.

I said good-bye to Allison and Turk. Allison begged me to take up the offer the ambassador had made and stay here, embodied or not. She wept when I refused, but I was adamant. I didn’t want another incarnation. I hadn’t sought or wanted this one.

Turk stayed a while after Allison left the room. He said, “I sometimes wonder whether something singled us out for all this—for everything that happened to us. It all seems so strange, doesn’t it? Not like other people’s lives.”

Not much like, I agreed. But I didn’t think we had been singled out. “It all could have happened countless other ways. There’s nothing special about us.”

“You think you’ll find something at the end of it? Something that makes it all make sense?”

“I don’t know.” Peut-être. “We all fall. We all land somewhere.”

“You have a long trip ahead of you.”

“It won’t seem long to me. I’m traveling light.”

“You carry what you carry,” Turk Findley said.

I enclosed the city in its bubble of slowtime and borrowed sunlight for acceleration. Vox Core soared beyond the orbit of the system’s outermost planet, out into the interstellar vacuum and far from Cloud Harbor. From my vantage point this took only a moment. The city’s clocks ticked seconds for centuries.

I had no destination. Occasional brushes with massive stars skewed my trajectory in unpredictable vectors, a drunkard’s walk through the galaxy. Apart from avoiding obstacles, I did nothing to intervene.

In the physical body of Isaac Dvali I often wandered the tiers and passageways of Vox Core. The city persisted in its daily rhythms, regulating its atmosphere, tending its empty parks and gardens. On these walks I occasionally passed robotic maintenance machines as they rolled down public passageways, steel monks hurrying to their matins. They resembled people but they lacked moral agency, and I resisted the unreasonable urge to speak to them.

It was a pointless anachronism to preserve the cycle of day and night, but my mortal body preferred it. Days, I basked in artificial sunlight. Evenings, I read ancient books reproduced from the Voxish archives, or reread the memoirs Turk and Allison had left me.

Nights, while my body slept, I expanded my sense of self to include all of Vox Core. I modeled the aging galaxy and my place in it. I tapped trickles of information from the ever more complex skein of the Hypothetical ecology. Stars that had been young only moments ago exhausted their nuclear fuel and decayed into simmering embers: brown dwarfs, neutron stars, singularities in their bottomless graves. Compared to the passage of time in the exterior universe, my consciousness was vast and slow. This would have been the true viewpoint of the Hypotheticals, I imagined, had the Hypotheticals possessed a unitary consciousness.

Signals propagating at the speed of light passed between stars as quickly as one neuron communicated with the next in Isaac Dvali’s mortal brain. I began to become aware of the galaxy as a whole form, not just a collation of stellar oases separated by light-years of emptiness. Hypothetical networks ran through it like fungal hyphae through a rotten tree. In my night vision I saw this activity as threads of multicolored light, revealing a complex and otherwise invisible galactic structure. Thriving world-rings stood out like the closed chains of carbon atoms in an organic molecule. Ancient, dead rings shimmered like pale ghosts as the Hypothetical machines associated with them died for lack of resources or scattered to nearby stellar nurseries.

The living galaxy pulsed with exhaustion and renewal. New technologies and energy sources were discovered, exploited, shared.

And as the universe aged and expanded, other galaxies, already immensely distant, fled toward the limits of perceptibility. But even these faint, far structures had begun to reveal a hidden life of their own, emissions of stray signals suggesting they had evolved their own Hypothetical-like networks. They sang like unintelligible voices in the darkness, fading.

It was inevitable that I would have to abandon my mortal body and live exclusively in the processors of the Coryphaeus and in the cloud of Hypothetical nanotechnology surrounding Vox Core. But I still wanted to be able to move about the city in a physical way. So—as I allowed the body of Isaac Dvali to lie in a self-induced coma, dying of starvation—I fashioned a more durable substitute, a robotic body equipped with equivalent senses, in which I could instantiate my consciousness. When this project was complete I gathered the remains of my organic self in my inorganic arms and carried the corpse to a recycling station, feeding its useful proteins into the closed biochemical loops of Vox Core. I felt no remorse or grief, and why should I? I was what I had become. The fragile meat in which the message of myself had first traveled to the stars, the old somatic galaxy in its border of skin, I gladly fed to the city’s forests.

Vox Core wasn’t an entirely self-sufficient system. I was forced to harvest trace elements from stellar nebulae in order to replenish what couldn’t be recycled. Of course, in the long run, Vox Core was as mortal as all baryonic matter, even inside its temporal fortress. It was only a question of time.

I courted the end of all things.

Vox Core fell into a long elliptical orbit of the galactic core. I began to divide my awareness into saccades, moments of perception separated by long periods of inactivity, so that experiential time passed more quickly, even inside the temporal bubble surrounding Vox Core.

Entropy—in the form of broken chemical bonds, irreparable system failures, radioactive decay—gnawed at the city’s vitals. Blight and drought decimated the forests and rubble began to obstruct the public walkways. Maintenance robots expired for lack of maintenance. Atmospheric regulators—the city’s lungs—gasped and finally failed. The air of Vox Core would have been toxic, had there been anyone alive to breathe it.

The quantum processors of the Coryphaeus continued to function, protected by multiple redundancies. But that, too, was only temporary.

The universe grew colder. The galaxy’s stellar nurseries, the concentrations of dust and gas that gave birth to stars, had grown too thin to be fecund. Old stars guttered and died and were not replaced. The Hypothetical ecology retreated from this encroaching darkness to the galaxy’s dense core, harvesting the gravitational gradients of massive dark holes for energy.

And something else happened to the Hypothetical ecology as it sheltered in the galaxy’s still-beating heart: its information-processing mechanisms were co-opted and dominated by sentient species seeking to outlive their organic mortality. These rogue virtualities grew, encountered one another, and in some cases merged. (The human species was the source of one such sentient bloom, though its virtual descendents could hardly be called “human” in the classic sense.) Pools of post-mortal sentience began to cooperate in a collective decision-making process—a kind of cortical democracy, on a scale of light-years. The dying galaxy began to generate unitary thought.

None of these thoughts could be rendered in conventional language, though my larger self understood them, at least approximately.

I took a last walk in my robotic body through the ruins of Vox Core, its towers fractured and askew, its vast tiers dark or tremblingly half-lit. Vox had sailed the seas of several worlds, and was sailing now on the largest sea of all, but soon I would have to abandon it. I had already begun relocating my memories and identity to the cloud of Hypothetical nanodevices, which was linked in turn to the remaining Hypothetical networks, all powered by the dynamos of ancient singularities.

And even that last redoubt of order and meaning was doomed. Soon enough, the same phantom energy that had inflated the universe would unravel matter itself, leaving nothing but a dust of unbound subatomic particles. Then, I thought, the darkness would be absolute. And I could sleep.

But for now, Vox Core sailed on. Vacuum invaded its faltering defenses. Empty, it succumbed to emptiness. In the absence of induced gravity, its contents began to spill through breached walls into space.

Beyond it, outside of it, my somatic boundaries expanded disconcertingly.

The Hypothetical network grew denser and more complex as its virtual polities applied immense calculating power to the problem of survival. Gravitational anomalies suggested the existence of megastructures larger than the event horizon of the universe itself—shallow gradients of ghostly energy that might serve as a medium to carry organized intelligence out of the entropic desert. But how, and at what cost?

I didn’t participate in these debates. My own consciousness, though now totally incorporeal, was too limited to fully comprehend them. In any case the arguments could never have been rendered in words—the preamble to a single thought would have required thousands of volumes, a legion of interpreters, a vocabulary that had never existed.

The three-dimensional macrostructure of the universe began its ultimate collapse. Collapsing, it revealed new horizons. Hidden dimensions of space-time unfurled as new particles and forces crystallized from quantum foam. The ultimate darkness I had hoped for never arrived. The entity that had been the Hypothetical network—to which I was inextricably bound—expanded suddenly and exponentially.

But I can’t describe the realm we entered. We were forced to invent new senses to perceive it, new modes of thought to comprehend it.

We emerged into a vast fractal space of many dimensions and discovered we were not alone there. Multidimensional structures hosted entities that had subsumed the four-dimensional space-time that once contained us. As old as we were, these entities were older. As large as we had become, they were larger. We passed among them unnoticed or ignored.

From this new point of view, the universe I had inhabited became an object I could perceive in its entirety. It was a hypersphere embedded in a cloud of alternative states—the sum of all possible quantum trajectories from the big bang to the decay of matter. “Reality”—history as we had known or inferred it—was only the most likely of these possible trajectories. There were countless others, real in a different sense: a vast but finite set of paths not taken, a ghostly forest of quantum alternatives, the shores of an unknown sea.

Putting a message in a bottle and setting it adrift is a quixotic act, sublimely human. What would you write, if you wanted to write such a message? An equation? A confession? A poem?

This is my confession. This is my poem.

Deep in that cloud of unlived histories were unlived lives, infinitesimally small, buried in eons of time and light-centuries of space, unreal only because they had never been enacted or observed. I understood that it was within my power to touch them and thus to realize them. What followed, if I made such an intervention, would be a new and unpredictable tributary of time: not obliterating the old history but lying alongside it. The price would be my own awareness.

I could never enter that four-dimensional space-time. Any intervention I made would create a new history from that point forward… at the expense of my continued existence.

What is inevitable is not death but change. Change is the only abiding reality. The metaverse evolves, fractally and forever. Saints become sinners, sinners become saints. Dust becomes men, men become gods, gods become dust.

I wished I could say these things to Turk Findley.

I could have intervened in my own potential history, but I felt no urge or need to do so. I wanted my last act to be a gift, even if I couldn’t calculate its ultimate consequences.

Deep in the mirrored corridor of unenacted events, in a motel room on the outskirts of Raleigh, North Carolina, a woman performs a sexual act in exchange for a brown plastic vial containing what she believes to be a gram of methamphetamine. Her partner is an unemployed pneumatic drill operator on his way to California, where he has been offered a job in his cousin’s construction business. He doesn’t wear a condom when he penetrates the woman, and he drives away shortly after the act is consummated. The taste of meth he gave her when he rented the room was authentic, but the vial he leaves on the dresser contains only powdered sugar.

Orrin Mather’s existence is compromised from the moment of his inglorious conception. His anorexic mother delivers him prematurely. His infant body suffers the agonies of drug withdrawal. He survives, but his mother’s malnutrition and multiple addictions have taken a toll. Orrin will never be able to make and enact plans as easily as others do. He will often be surprised—usually unpleasantly—by the consequences of his actions.

I cannot make him a more perfect human being. That isn’t within my power. All I can give him are words. And by writing these words into the cerebellum of a child, I dissolve myself and make a shadow world real.

He lies sleeping on a mattress on the floor of a rented trailer home. His sister Ariel sits on a plastic chair a few feet away, eating cereal without milk from a chipped bowl, watching television with the sound turned down. Orrin dreams he is walking on a beach, though he has only seen beaches in movies. In his dream he sees something rolling in the surf—a bottle, its green glass faded by years of sunlight and salt water. He picks it up. The bottle is tightly sealed, but it opens, somehow, at his touch.

Papers tumble out and unfold themselves in his hand. Orrin hasn’t yet learned to read, but, magically, he can read these words. He reads them all, page after page. What he reads here, he will never forget.

My name is Turk Findley, he reads.

And: My name is Allison Pearl.

And: My name is Isaac Dvali.

My name is Isaac Dvali and

I can’t write this anymore.

My name is Orrin Mather. That’s what my name is.

My name is Orrin Mather, and I work in a greenhouse in Laramie, Wyoming.

In the greenhouse at this nursery where I work, there are paths between the plants and the seedling tables. That’s so you can get from one place to another. Also so you can work on the plants without stepping on them. Those paths all connect with one another. You can go this way or you can go that. It all has the same beginning and the same ending. Though you can only ever stand in one place at once.

I believe I was born with these dreams or memories about Turk Findley and Allison Pearl and Isaac Dvali. They troubled me much when I was younger. They came to me like visions. They blew through me like a wind, as my sister Ariel liked to say.

That’s why I went to Houston on the bus so suddenly. That’s why I wrote down my dreams in my notebooks.

Things in Houston didn’t happen the way I expected. (As you know, Dr. Cole, and I expect you’ll be the only one to read these pages… unless you show them to Officer Bose, which is all right with me if you do so.) I suppose I took a different path from how I dreamed it. I never robbed any stores, for instance. I guess I could have. God knows I was hungry and angry enough from time to time. But whenever I felt like hurting someone I thought about Turk Findley and the burning man (which was me!), and how terrible it would be to carry around the weight of another man’s death.

I work in the greenhouse mainly at night but they keep the big lights on all the time. It’s like a house where it’s always noon on a sunny day. I like the wetness in the air and the smell of growing things, even the sharp smell of the chemical fertilizer. Do you remember those flowers outside my room at State Care, Dr. Cole? Bird of paradise you said they were called. They look like one thing but they’re really another. But they didn’t choose to look like that. They’re just what time and nature made of them.

We don’t grow that kind of flower in the greenhouse where I work. But I remember how pretty they were. They really do look like birds, don’t they?

I don’t believe I will write to you again, Dr. Cole. Please don’t take that the wrong way. It’s only that I want to put these troublesome things behind me.

The people Officer Bose introduced me to have been real kind. They found me this job, and a place for Ariel and me to live. They are good people, even if what they do is outside of the law. They are not criminals exactly. They just think they can invent a better way of living.

Maybe they will succeed at their work. If they do then maybe the world won’t turn barren and poisonous, like in the dreams I wrote down. I hope that is the case.

I don’t know, of course. But you can trust these people, Dr. Cole.

And I know you trust Officer Bose. He helped me when he didn’t have to. He’s a good man, I believe.

I thank him, and I thank you for the same reason.

Well, that is all I have to say. I have to go to work pretty soon.

Don’t expect to hear from me again.

Ariel sends her kind regards, and asks me to tell you that Houston is too damn hot.
