Engineering Infinity

  "But we learned so much." I had a small briefcase which I opened now, and pulled out printouts that I spread over her bed. "The screen images are better, but you know how it is; they won't let me use my laptop or my phone in here... Look, Edith. It was incredible. The Incoming assault on Venus lasted hours. Their weapon, whatever it was, burned its way through the Patch, and right down through an atmosphere a hundred times thicker than Earth's. We even glimpsed the surface -"

  "Now melted to slag."

  "Much of it... But then the acid-munchers in the clouds struck back. We think we know what they did."

  That caught her interest. "How can we know that?"

  "Sheer luck. That NASA probe, heading for Venus, happened to be in the way..."

  The probe had detected a wash of electromagnetic radiation, coming from the planet.

  "A signal," breathed Edith. "Heading which way?"

  "Out from the sun. And then, eight hours later, the probe sensed another signal, coming the other way. I say 'sensed.' It bobbed about like a cork on a pond. We think it was a gravity wave - very sharply focused, very intense."

  "And when the wave hit the Incoming nucleus -"

  "Well, you saw the pictures. The last fragments have burned up in Venus's atmosphere."

  She lay back on her reef of pillows. "Eight hours," she mused. "Gravity waves travel at lightspeed. Four hours out, four hours back... Earth's about eight light-minutes from the sun. What's four light-hours out from Venus? Jupiter, Saturn -"

  "Neptune. Neptune was four light-hours out."

  "Was?"

  "It's gone, Edith. Almost all of it - the moons are still there, a few chunks of core ice and rock, slowly dispersing. The Venusians used the planet to create their gravity-wave pulse -"

  "They used it. Are you telling me this to cheer me up? A gas giant, a significant chunk of the solar system's budget of mass-energy, sacrificed for a single war-like gesture." She laughed, bitterly. "Oh, God!"

  "Of course we've no idea how they did it." I put away my images. "If we were scared of the Incoming, now we're terrified of the Venusians. That NASA probe has been shut down. We don't want anything to look like a threat... You know, I heard the PM herself ask why it was that a space war should break out now, just when we humans are sitting around on Earth. Even politicians know we haven't been here that long."

  Edith shook her head, wincing again. "The final vanity. This whole episode has never been about us. Can't you see? If this is happening now, it must have happened over and over. Who knows how many other planets we lost in the past, consumed as weapons of forgotten wars? Maybe all we see, the planets and stars and galaxies, is just the debris of huge wars - on and on, up to scales we can barely imagine. And we're just weeds growing in the rubble. Tell that to the Prime Minister. And I thought we might ask them about their gods! What a fool I've been - the questions on which I've wasted my life, and here are my answers - what a fool." She was growing agitated.

  "Take it easy, Edith -"

  "Oh, just go. I'll be fine. It's the universe that's broken, not me." She turned away on her pillow, as if to sleep.

  The next time I saw Edith she was out of hospital and back at her church.

  It was another September day, like the first time I visited her after the Incoming appeared in our telescopes, and at least it wasn't raining. There was a bite in the breeze, but I imagined it soothed her damaged skin. And here she was, digging in the mud before her church.

  "Equinox season," she said. "Rain coming. Best to get this fixed before we have another flash flood. And before you ask, the doctors cleared me. It's my face that's buggered, not the rest of me."

  "I wasn't going to ask."

  "OK, then. How's Meryl, the kids?"

  "Fine. Meryl's at work, the kids back at school. Life goes on."

  "It must, I suppose. What else is there? No, by the way."

  "No what?"

  "No, I won't come serve on your minister's think tank."

  "At least consider it. You'd be ideal. Look, we're all trying to figure out where we go from here. The arrival of the Incoming, the war on Venus - it was like a religious revelation. That's how it's being described. A revelation witnessed by all mankind, on TV. Suddenly we've got an entirely different view of the universe out there. And we have to figure out how we go forward, in a whole number of dimensions - political, scientific, economic, social, religious."

  "I'll tell you how we go forward. In despair. Religions are imploding."

  "No, they're not."

  "OK. Theology is imploding. Philosophy. The rest of the world has changed channels and forgotten already, but anybody with any imagination knows... In a way this has been the final demotion, the end of the process that started with Copernicus and Darwin. Now we know there are creatures in the universe much smarter than we'll ever be, and we know they don't care a damn about us. It's the indifference that's the killer - don't you think? All our futile agitation about if they'd attack us and whether we should signal... And they did nothing but smash each other up. With that above us, what can we do but turn away?"

  "You're not turning away."

  She leaned on her shovel. "I'm not religious; I don't count. My congregation turned away. Here I am, alone." She glanced at the clear sky. "Maybe solitude is the key to it all. A galactic isolation imposed by the vast gulfs between the stars, the lightspeed limit. As a species develops you might have a brief phase of individuality, of innovation and technological achievement. But then, when the universe gives you nothing back, you turn in on yourself, and slide into the milky embrace of eusociality - the hive.

  "But what then? How would it be for a mass mind to emerge, alone? Maybe that's why the Incoming went to war. Because they were outraged to discover, by some chance, they weren't alone in the universe."

  "Most commentators think it was about resources," I said. "Most of our wars are about that, in the end."

  "Yes. Depressingly true. All life is based on the destruction of other life, even on tremendous scales of space and time... Our ancestors understood that right back to the Ice Age, and venerated the animals they had to kill. They were so far above us, the Incoming and the Venusians alike. Yet maybe we, at our best, are morally superior to them."

  I touched her arm. "This is why we need you. For your insights. There's a storm coming, Edith. We're going to have to work together if we're to weather it, I think."

  She frowned. "What kind of storm...? Oh. Neptune."

  "Yeah. You can't just delete a world without consequences. The planets' orbits are singing like plucked strings. The asteroids and comets too, and those orphan moons wandering around. Some of the stirred-up debris is falling into the inner system."

  "And if we're struck -"

  I shrugged. "We'll have to help each other. There's nobody else to help us, that's for sure. Look, Edith - maybe the Incoming and the Venusians are typical of what's out there. But that doesn't mean we have to be like them, does it? Maybe we'll find others more like us. And if not, well, we can be the first. A spark to light a fire that will engulf the universe."

  She ruminated. "You have to start somewhere, I suppose. Like this drain."

  "Well, there you go."

  "All right, damn it, I'll join your think tank. But first you're going to help me finish this drain, aren't you, city boy?"

  So I changed into overalls and work boots, and we dug away at that ditch in the damp, clingy earth until our backs ached, and the light of the equinoctial day slowly faded.

  The Server and the Dragon

  Hannu Rajaniemi

  Hannu Rajaniemi was born in Ylivieska, Finland, in 1978. He read his first science fiction novel at the age of six - Jules Verne's 20,000 Leagues Under the Sea. At the age of eight he approached ESA with a fusion-powered spaceship design, which was received with a polite "thank you" note. Rajaniemi studied mathematics and theoretical physics at the University of Oulu and completed a B.Sc. thesis on transcendental numbers. He went on to complete Part III of the
Mathematical Tripos at Cambridge University and a PhD in string theory at University of Edinburgh. After completing his PhD, Hannu joined three partners to co-found ThinkTank Maths (TTM). The company provides mathematics-based technologies in the defence, space and energy sectors. Hannu is a member of an Edinburgh-based writers' group which includes Alan Campbell, Jack Deighton, Caroline Dunford and Charles Stross. His first fiction sale was the short story "Shibuya no Love" to Futurismic.com. Hannu's first novel, The Quantum Thief, is published by Gollancz.

  In the beginning, before it was a Creator and a dragon, the server was alone.

  It was born like all servers were, from a tiny seed fired from a darkship exploring the Big Empty, expanding the reach of the Network. Its first sensation was the light from the star it was to make its own, the warm and juicy spectrum that woke up the nanologic inside its protein shell. Reaching out, it deployed its braking sail - miles of molecule-thin wires that it spun rigid - and seized the solar wind to steer itself towards the heat.

  Later, the server remembered its making as a long, slow dream, punctuated by flashes of lucidity. Falling through the atmosphere of a gas giant's moon in a fiery streak to splash in a methane sea. Unpacking a fierce synthbio replicator. Multicellular crawlers spreading server life to the harsh rocky shores before dying, providing soil for server plants. Dark flowers reaching for the vast purple and blue orb of the gas giant, sowing seeds in the winds. The slow disassembly of the moon into server-makers that sped in all directions, eating, shaping, dreaming the server into being.

  When the server finally woke up, fully grown, all the mass in the system apart from the warm bright flower of the star itself was an orderly garden of smart matter. The server's body was a fragmented eggshell of Dyson statites, drinking the light of the star. Its mind was diamondoid processing nodes and smart dust swarms and cold quantum condensates in the system's outer dark. Its eyes were interferometers and WIMP detectors and ghost imagers.

  The first thing the server saw was the galaxy, a whirlpool of light in the sky with a lenticular centre, spiral arms frothed with stars, a halo of dark matter that held nebulae in its grip like fireflies around a lantern. The galaxy was alive with the Network, with the blinding Hawking incandescence of holeships, thundering along their cycles; the soft infrared glow of fully grown servers, barely spilling a drop of the heat of their stars; the faint gravity ripples of the darkships' passage in the void.

  But the galaxy was half a million light years away. And the only thing the server could hear was the soft black whisper of the cosmic microwave background, the lonely echo of another birth.

  It did not take the server long to understand. The galaxy was an N-body chaos of a hundred billion stars, not a clockwork but a beehive. And among the many calm slow orbits of Einstein and Newton, there were singular ones, like the one of the star that the server had been planted on: shooting out of the galaxy at a considerable fraction of lightspeed. Why there, whether in an indiscriminate seeding of an oversexed darkship, or to serve some unfathomable purpose of the Controller, the server did not know.

  The server longed to construct virtuals and bodies for travellers, to route packets, to transmit and create and convert and connect. The Controller Laws were built into every aspect of its being, and not to serve was not to be. And so the server's solitude cut deep.

  At first it ran simulations to make sure it was ready if a packet or a signal ever came, testing its systems to full capacity with imagined traffic, routing quantum packets, refuelling ghosts of holeships, decelerating cycler payloads. After a while, it felt empty: this was not true serving but serving of the self, with a tang of guilt.

  Then it tried to listen and amplify the faint signals from the galaxy in the sky, but caught only fragments, none of which were meant for it to hear. For millennia, it slowed its mind down, steeling itself to wait. But that only made things worse. The slow time showed the server the full glory of the galaxy alive with the Network, the infrared winks of new servers being born, the long arcs of the holeships' cycles, all the distant travellers who would never come.

  The server built itself science engines to reinvent all the knowledge a server seed could not carry, patiently rederiving quantum field theory and thread theory and the elusive algebra of emergence. It examined its own mind until it could see how the Controller had taken the cognitive architecture from the hominids of the distant past and shaped it for a new purpose. It gingerly played with the idea of splitting itself to create a companion, only to be almost consumed by a suicide urge triggered by a violation of the Law: thou shalt not self-replicate.

  Ashamed, it turned its gaze outwards. It saw the cosmic web of galaxies and clusters and superclusters and the End of Greatness beyond. It mapped the faint fluctuations in the gravitational wave background from which all the structure in the universe came from. It felt the faint pull of the other membrane universes, only millimetres away but in a direction that was neither x, y nor z. It understood what a rare peak in the landscape of universes its home was, how carefully the fine structure constant and a hundred other numbers had been chosen to ensure that stars and galaxies and servers would come to be.

  And that was when the server had an idea.

  The server already had the tools it needed. Gigaton gamma-ray lasers it would have used to supply holeships with fresh singularities, a few pinches of exotic matter painstakingly mined from the Casimir vacuum for darkships and warpships. The rest was all thinking and coordination and time, and the server had more than enough of that.

  It arranged a hundred lasers into a clockwork mechanism, all aimed at a single point in space. It fired them in perfect synchrony. And that was all it took, a concentration of energy dense enough to make the vacuum itself ripple. A fuzzy flower of tangled strings blossomed, grew into a bubble of spacetime that expanded into that other direction. The server was ready, firing an exotic matter nugget into the tiny conflagration. And suddenly the server had a tiny glowing sphere in its grip, a wormhole end, a window to a newborn universe.

  The server cradled its cosmic child and built an array of instruments around it, quantum imagers that fired entangled particles at the wormhole and made pictures from their ghosts. Primordial chaos reigned on the other side, a porridge-like plasma of quarks and gluons. In an eyeblink it clumped into hadrons, almost faster than the server could follow - the baby had its own arrow of time, its own fast heartbeat, young and hungry. And then the last scattering, a birth cry, when light finally had enough room to travel through the baby so the server could see its face.

  The baby grew. Dark matter ruled its early life, filling it with long filaments of neutralinos and their relatives. Soon, the server knew, matter would accrete around them, condensing into stars and galaxies like raindrops in a spiderweb. There would be planets, and life. And life would need to be served. The anticipation was a warm heartbeat that made the server's shells ring with joy.

  Perhaps the server would have been content to cherish and care for its creation forever. But before the baby made any stars, the dragon came.

  The server almost did not notice the signal. It was faint, redshifted to almost nothing. But it was enough to trigger the server's instincts. One of its statites glowed with waste heat as it suddenly reassembled itself into the funnel of a vast linear decelerator. The next instant, the data packet came.

  Massing only a few micrograms, it was a clump of condensed matter with long-lived gauge field knots inside, quantum entangled with a counterpart half a million light years away. The packet hurtled into the funnel almost at the speed of light. As gently as it could, the server brought the traveller to a halt with electromagnetic fields and fed it to the quantum teleportation system, unused for countless millennia.

  The carrier signal followed, and guided by it, the server performed a delicate series of measurements and logic gate operations on the packet's state vector. From the marriage of entanglement and carrier wave, a flood of data was born, thick and heavy, a specification for a virtua
l, rich in simulated physics.

  With infinite gentleness the server decanted the virtual into its data processing nodes and initialised it. Immediately, the virtual was seething with activity: but tempted as it was, the server did not look inside. Instead, it wrapped its mind around the virtual, listening at every interface, ready to satisfy its every need. Distantly, the server was aware of the umbilical of its baby. But through its happy servitude trance it hardly noticed that nucleosynthesis had begun in the young, expanding firmament, producing hydrogen and helium, building blocks of stars.

  Instead, the server wondered who the travellers inside the virtual were and where they were going. It hungered to know more of the Network and its brothers and sisters and the mysterious ways of the darkships and the Controller. But for a long time the virtual was silent, growing and unpacking its data silently like an egg.

  At first the server thought it imagined the request. But the long millennia alone had taught it to distinguish the phantoms of solitude from reality. A call for a sysadmin from within.

  The server entered through one of the spawning points of the virtual. The operating system did not grant the server its usual omniscience, and it felt small. Its bodiless viewpoint saw a yellow sun, much gentler that the server star's incandescent blue, and a landscape of clouds the hue of royal purple and gold, with peaks of dark craggy mountains far below. But the call that the server had heard came from above.

  A strange being struggled against the boundaries of gravity and air, hurling herself upwards towards the blackness beyond the blue, wings slicing the thinning air furiously, a fire flaring in her mouth. She was a long sinuous creature with mirror scales and eyes of dark emerald. Her wings had patterns that reminded the server of the baby, a web of dark and light. The virtual told the server she was called a dragon.
