Supermen: Tales of the Posthuman Future

by Gardner Dozois

  I opened my mouth, but this time I had no answer. Something of his primitivism, his heedless, reckless thirst for life which discounted peril and hardship, reminded me of the person I had once been, an age ago.

  I considered the next one hundred years, and beyond. I had reached that time of my life when all experience seemed jejune and passé; I had come to the point, after all, where I had even considered Quietus.

  To go beyond the uncharted, to endanger oneself in the quest for knowledge, to think the unthinkable…

  It was ridiculous— but why, then, did the notion bring tears to my eyes?

  I hurried across the dome and took his arm. "Come," I said, leading him toward the skin of the hemisphere.

  "Where—?" he began.

  But we were already outside the dome, and then through the skin of another, and walking across the silver-gray regolith of the lunar surface.

  He stopped and gazed about in wonder. "Christ," he whispered. "Oh, Christ, I never thought…"

  "Over here," I said, leading him.

  We crossed the plain toward the display, unchanged in thirty thousand years. He stared at the lunar module, stark beneath the unremitting light of the Sun. We stood on the platform encircling the display and stared down at the footprints the first astronauts had laid upon the surface of another world.

  He looked at me, his expression beatific. "I often dreamed," he said, "but I never thought I'd ever return."

  I smiled. I shared the emotions he experienced then. I knew what it was to return. I recalled the time, not long after my rebirth in this miraculous age, when I had made the pilgrimage to Earth and looked again upon the cell where over thirty thousand years ago, I, Galileo Galilei, had been imprisoned for my beliefs.

  Haltingly, I told Armstrong who I was. We stared up into the dark sky, past the earth and the brilliant Sun, to the wonders awaiting us in the uncharted universe beyond.

  We embraced for a long minute, and then turned and retraced our steps across the surface of the Moon toward the domes of the Academy, where Severnius would be awaiting my decision.

  GREG EGAN

  Looking back at the century that has just ended, it's obvious that Australian writer Greg Egan was one of the Big New Names to emerge in SF in the nineties, and is probably one of the most significant talents to enter the field in the last several decades. Already one of the most widely known of all Australian genre writers, Egan may well be the best new "hard science" writer to enter the field since Greg Bear, and he is still growing in range, power, and sophistication. In the last few years, he has become a frequent contributor to Interzone and Asimov's Science Fiction, and has made sales as well as to Pulphouse, Analog, Aurealis, Eidolon, and elsewhere. Many of his stories have also appeared in various "Best of the Year" series, and he was on the Hugo Final Ballot in 1995 for his story "Cocoon," which won the Ditmar Award and the Asimov's Readers Award. His first novel Quarantine appeared in 1992; his second novel Permutation City won the John W. Campbell Memorial Award in 1994. He won the Hugo Award in 1999 for his novella "Oceanic." His other books include the novels Distress and Diaspora and three collections of his short fiction, Axiomatic, Luminous, and Our Lady of Chemobyl. His most recent book is a major new novel, Teranesia. He has a Web site at http://www.netspace.netau/^gregegan/.

  Almost any story by Egan would have served perfectly well for this anthology. In fact, with the possible exception of Brian Stableford, Egan has probably written more about the posthuman future than any other writer of the last decade— being one of the key players in shaping current ideas about that future— and there were more than a dozen possibilities to choose from, including stories such as "Learning to Be Me," "Dust," "Fidelity," "Reasons to be Cheerful," "The Planck Dive," "Tap," "Oceanic," and many others ("Wang's Carpets" would have been perfect, but I had already used it in another of these anthologies). In fact, if I'd had room here to include two stories by any one author (which I didn't have), Egan would have been the one.

  I finally settled on the dazzlingly imaginative story that follows, as it takes us as deep into that posthuman future as anything that Egan has yet written, for a compelling study of old loyalties and new possibilities.

  In the early afternoon of his fourth day out of sadness, Jamil was wandering home from the gardens at the center of Noether when he heard shouts from the playing field behind the library. On the spur of the moment, without even asking the city what game was in progress, he decided to join in.

  As he rounded the corner and the field came into view, it was clear from the movements of the players that they were in the middle of a quantum soccer match. At Jamil's request, the city painted the wave function of the hypothetical ball across his vision, and tweaked him to recognize the players as the members of two teams without changing their appearance at all. Maria had once told him that she always chose a literal perception of color-coded clothing instead; she had no desire to use pathways that had evolved for the sake of sorting people into those you defended and those you slaughtered. But almost everything that had been bequeathed to them was stained with blood, and to Jamil it seemed a far sweeter victory to adapt the worst relics to his own ends than to discard them as irretrievably tainted.

  The wave function appeared as a vivid auroral light, a quicksilver plasma bright enough to be distinct in the afternoon sunlight, yet unable to dazzle the eye or conceal the players running through it. Bands of color representing the complex phase of the wave swept across the field, parting to wash over separate rising lobes of probability before hitting the boundary and bouncing back again, inverted. The match was being played by the oldest, simplest rules: semiclassical, nonrelativistic. The ball was confined to the field by an infinitely high barrier, so there was no question of it tunneling out, leaking away as the match progressed. The players were treated classically: their movements pumped energy into the wave, enabling transitions from the game's opening state— with the ball spread thinly across the entire field— into the range of higher-energy modes needed to localize it. But localization was fleeting; there was no point forming a nice sharp wave packet in the middle of the field in the hope of kicking it around like a classical object. You had to shape the wave in such a way that all of its modes— cycling at different frequencies, traveling with different velocities— would come into phase with each other, for a fraction of a second, within the goal itself. Achieving that was a matter of energy levels, and timing.

  Jamil had noticed that one team was under-strength. The umpire would be skewing the field's potential to keep the match fair; but a new participant would be especially welcome for the sake of restoring symmetry. He watched the faces of the players, most of them old friends. They were frowning with concentration, but breaking now and then into smiles of delight at their small successes, or their opponents' ingenuity.

  He was badly out of practice, but if he turned out to be dead weight he could always withdraw. And if he misjudged his skills, and lost the match with his incompetence? No one would care. The score was nil all; he could wait for a goal, but that might be an hour or more in coming. Jamil communed with the umpire and discovered that the players had decided in advance to allow new entries at any time.

  Before he could change his mind, he announced himself. The wave froze, and he ran onto the field. People nodded greetings, mostly making no fuss, though Ezequiel shouted, "Welcome back!" Jamil suddenly felt fragile again; though he'd ended his long seclusion four days before, it was well within his power, still, to be dismayed by everything the game would involve. His recovery felt like a finely balanced optical illusion, a figure and ground that could change roles in an instant, a solid cube that could evert into a hollow.

  The umpire guided him to his allotted starting position, opposite a woman he hadn't seen before. He offered her a formal bow, and she returned the gesture. This was no time for introductions, but he asked the city if she'd published a name. She had: Margit.

  The ump
ire counted down in their heads. Jamil tensed, regretting his impulsiveness. For seven years he'd been dead to the world. After four days back, what was he good for? His muscles were incapable of atrophy, his reflexes could never be dulled, but he'd chosen to live with an unconstrained will, and at any moment his wavering resolve could desert him.

  The umpire said, "Play." The frozen light around Jamil came to life, and he sprang into motion.

  Each player was responsible for a set of modes, particular harmonics of the wave that were theirs to fill, guard, or deplete as necessary. Jamil's twelve modes cycled at between 1,000 and 1,250 milliHertz. The rules of the game endowed his body with a small, fixed potential energy, which repelled the ball slightly and allowed different modes to push and pull on each other through him, but if he stayed in one spot as the modes cycled, every influence he exerted would eventually be replaced by its opposite, and the effect would simply cancel itself out.

  To drive the wave from one mode to another, you needed to move, and to drive it efficiently, you needed to exploit the way the modes fell in and out of phase with each other: to take from a 1,000-milliHertz mode and give to a 1,250, you had to act in synch with the quarter-Hertz beat between them. It was like pushing a child's swing at its natural frequency, but rather than setting a single child in motion, you were standing between two swings and acting more as an intermediary: trying to time your interventions in such a way as to speed up one child at the other's expense. The way you pushed on the wave at a given time and place was out of your hands completely, but by changing location in just the right way, you could gain control over the interaction. Every pair of modes had a spatial beat between them— like the moiré pattern formed by two sheets of woven fabric held up to the light together, shifting from transparent to opaque as the gaps between the threads fell in and out of alignment. Slicing through this cyclic landscape offered the perfect means to match the accompanying chronological beat.

  Jamil sprinted across the field at a speed and angle calculated to drive two favorable transitions at once. He'd gauged the current spectrum of the wave instinctively, watching from the sidelines, and he knew which of the modes in his charge would contribute to a goal and which would detract from the probability. As he cut through the shimmering bands of color, the umpire gave him tactile feedback to supplement his visual estimates and calculations, allowing him to sense the difference between a cyclic tug, a to and fro that came to nothing, and the gentle but persistent force that meant he was successfully riding the beat.

  Chusok called out to him urgently, "Take, take! Two-ten!" Everyone's spectral territory overlapped with someone else's, and you needed to pass amplitude from player to player as well as trying to manage it within your own range. Two-ten— a harmonic with two peaks across the width of the field and ten along its length, cycling at 1,160 milliHertz— was filling up as Chusok drove unwanted amplitude from various lower-energy modes into it. It was Jamil's role to empty it, putting the amplitude somewhere useful. Any mode with an even number of peaks across the field was unfavorable for scoring, because it had a node— a zero point between the peaks— smack in the middle of both goals.

  Jamil acknowledged the request with a hand signal and shifted his trajectory. It was almost a decade since he'd last played the game, but he still knew the intricate web of possibilities by heart: he could drain the two-ten harmonic into the three-ten, five-two and five-six modes— all with "good parity," peaks along the center-line— in a single action.

  As he pounded across the grass, carefully judging the correct angle by sight, increasing his speed until he felt the destructive beats give way to a steady force like a constant breeze, he suddenly recalled a time— centuries before, in another city— when he'd played with one team, week after week, for forty years. Faces and voices swam in his head. Hashim, Jamil's ninety-eighth child, and Hashim's granddaughter Laila had played beside him. But he'd burned his house and moved on, and when that era touched him at all now, it was like an unexpected gift. The scent of the grass, the shouts of the players, the soles of his feet striking the ground, resonated with every other moment he'd spent the same way, bridging the centuries, binding his life together. He never truly felt the scale of it when he sought it out deliberately; it was always small things, tightly focused moments like this, that burst the horizon of his everyday concerns and confronted him with the astonishing vista.

  The two-ten mode was draining faster than he'd expected; the seesawing center-line dip in the wave was vanishing before his eyes. He looked around, and saw Margit performing an elaborate Lissajous maneuver smoothly orchestrating a dozen transitions at once. Jamil froze and watched her, admiring her virtuosity while he tried to decide what to do next; there was no point competing with her when she was doing such a good job of completing the task Chusok had set him.

  Margit was his opponent, but they were both aiming for exactly the same kind of spectrum. The symmetry of the field meant that any scoring wave would work equally well for either side— but only one team could be the first to reap the benefit, the first to have more than half the wave's probability packed into their goal. So the two teams were obliged to cooperate at first, and it was only as the wave took shape from their combined efforts that it gradually became apparent which side would gain by sculpting it to perfection as rapidly as possible, and which would gain by spoiling it for the first chance, then honing it for the rebound.

  Penina chided him over her shoulder as she jogged past, "You want to leave her to clean up four-six, as well?" She was smiling, but Jamil was stung; he'd been motionless for ten or fifteen seconds. It was not forbidden to drag your feet and rely on your opponents to do all the work, but it was regarded as a shamefully impoverished strategy. It was also very risky, handing them the opportunity to set up a wave that was almost impossible to exploit yourself.

  He reassessed the spectrum, and quickly sorted through the alternatives. Whatever he did would have unwanted side effects; there was no magic way to avoid influencing modes in other players' territory, and any action that would drive the transitions he needed would also trigger a multitude of others, up and down the spectrum. Finally, he made a choice that would weaken the offending mode while causing as little disruption as possible.

  Jamil immersed himself in the game, planning each transition two steps in advance, switching strategy halfway through a run if he had to, but staying in motion until the sweat dripped from his body, until his calves burned, until his blood sang. He wasn't blinded to the raw pleasures of the moment, or to memories of games past, but he let them wash over him, like the breeze that rose up and cooled his skin with no need for acknowledgment. Familiar voices shouted terse commands at him; as the wave came closer to a scoring spectrum, every trace of superfluous conversation vanished, every idle glance gave way to frantic, purposeful gestures. To a bystander, this might have seemed like the height of dehumanization: twenty-two people reduced to grunting cogs in a pointless machine. Jamil smiled at the thought but refused to be distracted into a complicated imaginary rebuttal. Every step he took was the answer to that, every hoarse plea to Yann or Joracy, Chusok or Maria, Eudore or Halide. These were his friends, and he was back among them. Back in the world.

  The first chance of a goal was thirty seconds away, and the opportunity would fall to Jamil's team; a few tiny shifts in amplitude would clinch it. Margit kept her distance, but Jamil could sense her eyes on him constantly— and literally feel her at work through his skin as she slackened his contact with the wave. In theory, by mirroring your opponent's movements at the correct position on the field, you could undermine everything they did, though in practice, not even the most skillful team could keep the spectrum completely frozen. Going further and spoiling was a tug of war you didn't want to win too well: if you degraded the wave too much, your opponent's task— spoiling your own subsequent chance at a goal— became far easier.

  Jamil still had two bad-parity modes that he was hoping to weaken, but every time he changed veloc
ity to try a new transition, Margit responded in an instant, blocking him. He gestured to Chusok for help; Chusok had his own problems with Ezequiel, but he could still make trouble for Margit by choosing where he placed unwanted amplitude. Jamil shook sweat out of his eyes; he could see the characteristic "stepping stone" pattern of lobes forming, a sign that the wave would soon converge on the goal, but from the middle of the field it was impossible to judge their shape accurately enough to know what, if anything, remained to be done.

  Suddenly, Jamil felt the wave push against him. He didn't waste time looking around for Margit; Chusok must have succeeded in distracting her. He was almost at the boundary line, but he managed to reverse smoothly, continuing to drive both the transitions he'd been aiming for.

  Two long lobes of probability, each modulated by a series of oscillating mounds, raced along the sides of the field. A third, shorter lobe running along the center-line melted away, reappeared, then merged with the others as they touched the end of the field, forming an almost rectangular plateau encompassing the goal.

  The plateau became a pillar of light, growing narrower and higher as dozens of modes, all finally in phase, crashed together against the impenetrable barrier of the field's boundary. A shallow residue was still spread across the entire field, and a diminishing sequence of elliptical lobes trailed away from the goal like a staircase, but most of the wave that had started out lapping around their waists was now concentrated in a single peak that towered above their heads, nine or ten meters tall.
