  ‘If they existed, they would be here’ ENRICO FERMI. In the second volume in Stephen Baxter's epic Manifold Series Reid Malenfant inhabits the universe Malenfant kick-started in TIME (‘science fiction at its best’ FHM) — and ‘they’ are here. When Nemoto, a Japanese researcher on the Moon, discovers evidence of extraterrestrial intelligence in the solar system, the Fermi Paradox provokes both Malenfant and Nemoto to question why now? Because, suddenly, there are signs of intelligent life in deep space in all directions. Deeper layers of Fermi’s paradox unravel as robot-like aliens, the Gaijin, seem to be e-mailing themselves from star to star, and wherever telescopes point, far away, other alien races are destroying worlds!

  Prologue

  My name is Reid Malenfant.

  You know me. And you know I’m an incorrigible space cadet.

  You know I’ve campaigned for, among other things, private mining expeditions to the asteroids. In fact, in the past I’ve tried to get you to pay for such things. I’ve bored you with that often enough already, right?

  So tonight I want to be a little more personal. Tonight I want to talk about why I gave over my life to a single, consuming project.

  It started with a simple question:

  Where is everybody?

  As a kid I used to lie at night out on the lawn, soaking up dew and looking at the stars, trying to feel the Earth turning under me. It felt wonderful to be alive — hell, to be ten years old, anyhow.

  But I knew that the Earth was just a ball of rock, on the fringe of a nondescript galaxy.

  As I lay there staring at the stars — the thousands I could pick out with my naked eyes, the billions that make up the great wash of our Galaxy, the uncounted trillions in the galaxies beyond — I just couldn’t believe, even then, that there was nobody out there looking back at me down here. Was it really possible that this was the only place where life had taken hold — that only here were there minds and eyes capable of looking out and wondering?

  But if not, where are they? Why isn’t there evidence of extraterrestrial civilization all around us?

  Consider this. Life on Earth got started just about as soon as it could — as soon as the rocks cooled and the oceans gathered. Of course it took a good long time to evolve us. Nevertheless we have to believe that what applies on Earth ought to apply on all the other worlds out there, like or unlike Earth; life ought to be popping up everywhere. And, as there are hundreds of billions of stars out there in the Galaxy, there are presumably hundreds of billions of opportunities for life to come swarming up out of the ponds — and even more opportunities in the other galaxies that crowd our universe.

  Furthermore, life spread over Earth as fast and as far as it could. And already we’re starting to spread to other worlds. Again, this can’t be a unique trait of Earth life.

  So, if life sprouts everywhere, and spreads as fast and as far as it can, how come nobody has come spreading all over us?

  The universe is a big place. There are huge spaces between the stars. But it’s not that big. Even crawling along with dinky ships that only reach a fraction of light speed — ships we could easily start building now — we could colonize the Galaxy in a few tens of millions of years. One hundred million, tops.

  One hundred million years. It seems an immense time — after all, one hundred million years ago the dinosaurs ruled Earth. But the Galaxy is one hundred times older still. There has been time for Galactic colonization to have happened many times since the birth of the stars.

  Remember, all it takes is for one race somewhere to have evolved the will and the means to colonize; and once the process has started it’s hard to see what could stop it.

  But, as a kid on that lawn, I didn’t see them. I seemed to be surrounded by emptiness and silence.

  Even we blare out on radio frequencies. Why, with our giant radio telescopes we could detect a civilization no more advanced than ours anywhere in the Galaxy. But we don’t.

  More advanced civilizations ought to be much more noticeable. We could spot somebody building a shell around their star, or throwing in nuclear waste. We could probably see evidence of such things even in other galaxies. But we don’t. Those other galaxies, other islands of stars, seem to be as barren as this one.

  Maybe we’re just unlucky. Maybe we’re living at the wrong time. The Galaxy is an old place; maybe They have been, flourished, and gone already. But consider this: Even if They are long gone, surely we should see Their mighty ruins, all around us. But we don’t even see that. The stars show no signs of engineering. The Solar System appears to be primordial, in the sense that it shows no signs of the great projects we can already envisage, like terraforming the planets, or tinkering with the Sun, and so on.

  We can think of lots of rationalizations for this absence.

  Maybe there is something that kills off every civilization like ours before we get too far — for example, maybe we all destroy ourselves in nuclear wars or eco collapse. Or maybe there is something more sinister: plagues of killer robots sliding silently between the stars, killing off fledgling cultures for their own antique purposes.

  Or maybe the answer is more benevolent. Maybe we’re in some kind of quarantine — or a zoo.

  But none of these filtering mechanisms convinces me. You see, you have to believe that this magic suppression mechanism, whatever it is, works for every race in this huge Galaxy of ours. All it would take would be for one race to survive the wars, or evade the vacuum robots, or come sneaking through the quarantine to sell trinkets to the natives — or even just to start broadcasting some ET version of The Simpsons, anywhere in the Galaxy — and we’d surely see or hear them.

  But we don’t.

  This paradox was first stated clearly by a twentieth-century physicist called Enrico Fermi. It strikes me as a genuine mystery. The contradictions are basic: Life seems capable of emerging everywhere; just one star-faring race could easily have covered the Galaxy by now; the whole thing seems inevitable — but it hasn’t happened.

  Thinking about paradoxes is the way human understanding advances. I think the Fermi paradox is telling us something very profound about the universe, and our place in it. Or was.

  Of course, everything is different now.

  …And he felt as if he were drowning, struggling up from some thick, viscous fluid, up toward the light. He wanted to open his mouth, to scream — but he had no mouth, and no words. What would he scream?

  I.

  I am.

  I am Reid Malenfant.

  He could see the sail.

  It was a gauzy sheet draped across the crowded stars of this place.

  Where, Malenfant? Why, the core of the Galaxy, he thought, wonder breaking through his agony.

  And within the sail, cupped, he could see the neutron star, an angry ball of red laced with eerie synchrotron blue, like a huge toy.

  A star with a sail attached to it. Beautiful. Scary.

  Triumph surged. I won, he thought. I resolved t
he koan, the great conundrum of the cosmos; Nemoto would be pleased. And now, together, we’re fixing an unsatisfactory universe. Hell of a thing.

  But if you see all this, Malenfant, then what are you?

  He looked down at himself.

  Tried to.

  A sense of body, briefly. Spread-eagled against the sail’s gauzy netting. Clinging by fingers and toes, monkey digits, here at the center of the Galaxy. A metaphor, of course, an illusion to comfort his poor human mind.

  Welcome to reality.

  The pain! Oh, God, the pain.

  Terror flooded over him. And anger.

  And, through it, he remembered the Moon, where it began…

  Chapter 1

  Gaijin

  A passenger in the Hope-3 tug, Reid Malenfant descended toward the Moon.

  The Farside base, called Edo, was a cluster of concrete components — habitation modules, power plants, stores, manufacturing facilities — half buried in the cratered plain. Comms masts sprouted like angular flowers. The tug pad was just a splash of scorched moondust concrete, a couple of kilometers farther out. Around the station itself, the regolith was scarred by tractor traffic.

  Robots were everywhere, rolling, digging, lifting; Edo was growing like a colony of bacilli in nutrient.

  A hi-no-maru, a Japanese Sun flag, was fixed to a pole at the center of Edo.

  “You are welcome to my home,” Nemoto said.

  She met him in the pad’s air lock: a large, roomy chamber blown into the regolith. Her face was broad, pale, her eyes black; her hair was elaborately shaved, showing the shape of her skull. She smiled, apparently habitually. She could have been no more than half Malenfant’s age, perhaps thirty.

  Nemoto helped Malenfant don the suit he’d been fitted with during the flight from Earth. The suit was a brilliant orange. It clung to him comfortably, the joints easy and loose, although the sewn-in plates of tungsten armor were heavy.

  “It’s a hell of a development from the old EMUs I wore when I was flying shuttle,” he said, trying to make conversation.

  Nemoto listened politely, after the manner of young people, to his fragments of reminiscence from a vanished age. She told him the suit had been manufactured on the Moon, and was made largely of spider silk. “I will take you to the factory. A chamber in the lunar soil, full of immense spinnerets. A nightmare vision!…”

  Malenfant felt disoriented, restless.

  He was here to deliver a lecture, on colonizing the Galaxy, to senior executives of Nishizaki Heavy Industries. But here he was being led off the tug by Nemoto, the junior researcher who’d invited him out to the Moon, just a kid. He hoped he wasn’t making some kind of fool of himself.

  Reid Malenfant used to be an astronaut. He’d flown the last shuttle mission — STS-194, on Discovery — when, ten years ago, the space transportation system had reached the end of its design life, and the International Space Station had finally been abandoned, incomplete. No American had flown into space since — save as the guest of the Japanese, or the Europeans, or the Chinese.

  In this year 2020, Malenfant was sixty years old and feeling a lot older — increasingly stranded, a refugee in this strange new century, his dignity woefully fragile.

  Well, he thought, whatever the dubious politics, whatever the threat to his dignity, he was here. It had been the dream of his long life to walk on another world. Even if it was as the guest of the Japanese.

  And even if he was too damn old to enjoy it.

  They stepped through a transit tunnel and directly into a small tractor, a lozenge of tinted glass. The tractor rolled away from the tug pad. The wheels were large and open, and absorbed the unevenness of the mare; Malenfant felt as if he were riding across the Moon in a soap bubble.

  Every surface in the cabin was coated with fine gray moondust. He could smell the dust; the scent was, as he knew it would be, like wood ash, or gunpowder.

  Beyond the window, the Mare Ingenii — the Sea of Longing — stretched to the curved horizon, pebble-strewn. It was late in the lunar afternoon, and the sunlight was low, flat, the shadows of the surface rubble long and sharp. The lighting was a rich tan when he looked away from the Sun, a more subtle gray elsewhere. Earth was hidden beneath the horizon, of course, but Malenfant could see a comsat crawl across the black sky.

  He longed to step through the glass, to touch that ancient soil.

  Nemoto locked in the autopilot and went to a little galley area. She emerged with green tea, rice crackers and dried ika cuttlefish. Malenfant wasn’t hungry, but he accepted the food. Such items as the fish were genuine luxuries here, he knew; Nemoto was trying to honor him.

  The motion of the tea, as she poured it in the one-sixth gravity, was complex, interesting.

  “I am honored you have accepted my invitation to travel here, to Edo,” Nemoto said. “You will, of course, tour the town, as you wish. There is even a Makudonarudo here: a McDonald’s. You may enjoy a bifubaaga ! Soya, of course.”

  He put down his plate and tried to meet her direct gaze. “Tell me why I’ve been brought out here. I don’t see how my work, on long-term space utilization, can be of real interest to your employers.”

  She eyed him. “You do have a lecture to deliver, I am afraid. But… no, your work is not of primary concern to Nishizaki.”

  “Then I don’t understand.”

  “It is I who invited you, I who arranged the funding. You ask why. I wished to meet you. I am a researcher, like you.”

  “Hardly a researcher,” he said. “I call myself a consultant, nowadays. I am not attached to a university.”

  “Nor I. Nishizaki Heavy Industries pays my wages; my research must be focused on serving corporate objectives.” She eyed him, and took some more fish. “I am salariman. A good company worker, yes? But I am, at heart, a scientist. And I have made some observations which I am unable to reconcile with the accepted paradigm. I searched for recent scientific publications concerning the subject area of my… hypothesis. I found only yours.

  “My subject is infrared astronomy. At our research station, away from Edo, the company maintains radiometers, photometers, photo-polarimeters, cameras. I work at a range of wavelengths, from twenty to a hundred microns. Of course a space-borne platform is to be preferred: The activities of humankind are thickening the Moon’s atmosphere with each passing day, blocking the invisible light I collect. But the lunar site is cheap to maintain, and is adequate for the company’s purposes. We are considering the future exploitation of the asteroids, you see. Infrared astronomy is a powerful tool in the study of those distant rocks. With it we can deduce a great deal about surface textures, compositions, internal heat, rotation characteristics—”

  “Tell me about your paradigm-busting hypothesis.”

  “Yes.” She sipped her green tea. “I believe I have observational evidence of the activity of extraterrestrial intelligences in the Solar System,” she said calmly.

  The silence stretched between them, electric. Her words were shocking, quite unexpected.

  But now he saw why she’d brought him here.

  Since his retirement from NASA, Malenfant had avoided following his colleagues into the usual ex-astronaut gravy ponds: lucrative aerospace executive posts and junior political positions. Instead, he’d thrown his weight behind research into what he regarded as long-term thinking: SETI, using gravitational lensing to hunt for planets and ET signals, advanced propulsion systems, schemes for colonizing the planets, terraforming, interstellar travel, exploration of the venerable Fermi paradox.

  All the stuff that Emma had so disapproved of. You’re wasting your time, Malenfant. Where’s the money to be made out of gravitational lensing?

  But his wife was long gone, of course, struck down by cancer: the result of a random cosmic accident, a heavy particle that had come whizzing out of an ancient supernova and flown across the universe to damage her just so… It could have been him; it could have been neither of them; it could have happened a few years later, w
hen cancer had been reduced to a manageable disease. But it hadn’t worked out like that, and Malenfant, burned out, already grounded, had been left alone.

  So he had thrown himself into his obsessions. What else was there to do?

  Well, Emma had been right, and wrong. He was making a minor living on the lecture circuit. But few serious people were listening, just as she had predicted. He attracted more knee-jerk criticism than praise or thoughtful response; in the last few years, he’d become regarded as not much more than a reliable talk-show crank.

  But now, this.

  He tried to figure out how to deal with this, what to say. Nemoto wasn’t like the Japanese he had known before, on Earth, with their detailed observance of reigi — the proper manner.

  She studied him, evidently amused. “You are surprised. Startled. You think, perhaps, I am not quite sane to voice such speculations. You are trapped on the Moon with a mad Japanese woman. The American nightmare!”

  He shook his head. “It’s not that.”

  “But you must see that my speculations are not so far removed from your own published work. Like myself, you are cautious. Nobody listens. And when you do find an audience, they do not take you seriously.”

  “I wouldn’t be so blunt about it.”

  “Your nation has turned inward,” Nemoto said. “Shrunk back.”

  “Maybe. We just have different priorities now.” In the U.S., flights into space had become a hobby of old men and women, dreams of an age of sublimated warfare that had left behind only images of charmingly antique rocket craft, endlessly copied around the data nets. Nothing to do with now.

  “Then why do you continue to argue, to talk, to expose yourself to ridicule?” she said.

  “Because…” Because if nobody thinks it, it definitely won’t happen.
