Madeleine glanced down for the last time through the FGB module’s picture window, at smoky accretion-disc light. The flower-ship skimmed past the flank of “God”; the netting structure swarmed around the pulsing core.
The Chaera thrashed in its tank.
Ben pulled down the heavy hatch between the modules — it hadn’t been closed since the flower-ship had swept them up from the surface of Earth’s Moon — and dogged it tight.
Madeleine was running a hasty computer program. “Remember the drill for a pressure-hull breach?” she called.
“Of course. But—”
“Three, two, one.”
There was a clatter of pyrotechnic bolts, an abrupt jolt.
“I just severed the FGB,” she said. “The explosive decompression should fire it in the right direction. I hope. I didn’t have time to check my figures, or verify my aim—”
Bits of radiation spat out like javelins as the core began to open.
“What have you done, Meacher?” Nemoto thundered.
She saw the FGB module for one last instant, its battered, patched-up form silhouetted against the gigantic cheek of “God.” In its way it was a magnificent sight, she thought: a stubby twentieth-century human artifact orbiting a black hole, fifty-four light-years from Earth.
And then the core opened.
The FGB Module got the X-ray pulse right in the rear end. Droplets of metal splashed across space… But the massive Russian construction lasted, long enough to shield the Chaera worldlets.
Just as Madeleine had intended.
The core closed; the surface of the net smoothed over. The slowly cooling stump of the FGB module drifted around the curve of the hole. Madeleine saluted it silently.
“The journey back is going to be cramped,” Ben said dryly.
The Saddle Point gateway hung before them, anonymous, eternal, indistinguishable from its copies in the Solar System, visible only by the reflected light of the accretion disc.
“You saved a world, Madeleine,” Ben said.
“But nobody asked you to,” virtual Nemoto said, her voice tinny. “You’re a meddler. Sentimental. You always were. The Chaera are still protesting. ‘Why did you hide God from us?’…”
Ben shrugged. “God is still there. I think all Madeleine has done is provide the Chaera with a little more time to consider how much perfection they really want to achieve.”
“Meacher, you’re such a fool,” Nemoto said.
Perhaps she was. But she knew that what she was learning — the dismal, stupid secret of the universe — would not leave her. And she wondered what she would find, when she reached home this time.
The blue glow of transition flooded over them, and there was an instant of searing, welcoming pain.
Chapter 17
Lessons
World after world after world.
He saw worlds something like Earth, but with oceans of ammonia or sulphuric acid or hydrocarbons, airs of neon or nitrogen or carbon monoxide. All of them alive, of course, one way or another.
But such relatively Earthlike planets turned out to be the exception.
He was shown a giant world closely orbiting a star called 70 Virginis. This world was a cloudy ball six times the mass of Jupiter. The Gaijin believed there were creatures living in those clouds: immense, whale-like beings feeding off the organics created in the air by the central star’s radiation. But colonists had visited here, long ago. At one pole of the planet there was what appeared to be an immense mining installation, perhaps there to extract organics or some other valuable volatile like helium-3. The installation was desolate, apparently scarred by battle.
Close to a star called Upsilon Andromedae, forty-nine light-years from Earth, he found a planet with Jupiter’s mass orbiting closer than Mercury to its Sun. It had been stripped of its cloud decks by the Sun’s heat, leaving an immense rocky ball with canyons deep enough to swallow Earth’s Moon. Malenfant saw creatures crawling through those deep shadows, immense beetlelike beings. They were protected from the Sun’s heat by tough carapaces and had legs like tree trunks strong enough to lift them against the ferocious gravity. Perhaps they fed off volatiles trapped in the eternal shadows, or seeping from the planet’s deep interior. Here the battles seemed to have been fought out over the higher ground; Malenfant saw a plain littered with the wreckage of starships.
Not far from the star Procyon there was a nomadic world, a world without a Sun, hurled by some random gravitational accident away from its parent star. It was in utter darkness, of course: a black ball swimming alone through space. But it was a big planet with a hydrogen-rich atmosphere; it warmed itself with the dwindling heat of the radioactive elements in its core, with volcanoes and earthquakes and tectonic shifts. Thus, under a lightless sky, there were oceans of liquid water — and in their depths life swarmed, feeding off minerals from the deeper hot rocks, not unlike the deep-sea animals that clustered around volcanic vents in Earth’s seas. Here, though, life was doomed, for the world’s core was inexorably cooling as the heat of its formation was lost.
But even this lonely planet had been subject to destructive exploitation by colonists; there were signs, Malenfant learned, of giant strip-mine gouges in the ocean floors, huge machines now abandoned, perhaps deliberately wrecked.
Everywhere, he had learned, life had emerged. But every world, every system, had been overrun by waves of colonization, followed by collapse or destructive wars — not once, but many times. Everywhere the sky was full of engineering, of ruins.
And the bad news continued. The universe itself could prove a deadly place. He was taken through a region a hundred light years-wide where world after world was dead, land and oceans littered with the diverse remains of separately evolved life.
There had been a gamma-ray burster explosion here, the Gaijin told him: the collision of two neutron stars, causing a three-dimensional shower of high-energy electromagnetic radiation and heavy particles that had wiped clean the worlds for light-years around. It had been a random cosmic accident that had cared nothing for culture and ambition, hope and love and dreams. Some life survived — on Earth, the deep-ocean forms, perhaps pond life, some insects would have endured the lethal showers. But nothing advanced made it through, and certainly nothing approaching sentience; after the accident, its effects over in weeks or months, it would require a hundred million years of patient evolution to fix the rent in life’s fabric suffered in this place.
But nothing was without cost, he learned; nothing without benefit. The intense energy pulse of nearby gamma-ray bursts could shape the evolution of young star systems; primordial dust was melted into dense iron-rich droplets that settled quickly to the central plain of a dust cloud and so accelerated the formation of planets. Without a close-by gamma-ray burst, it was possible that star systems like the Solar System could never have formed. Birth, amid death; the way of the universe.
Maybe. But such cold logic was no comfort for Malenfant.
The Gaijin seemed determined to show him as much as possible of this vast star-spanning graveyard, to drive home its significance. After a time it became unbearable, the lesson blinding in its cruelty: that if the universe didn’t get you, other sentient beings would.
