Peter Hamilton: Pandora's Star

Dudley closed his eyes and sighed. “And yet it moves,” he whispered.

As rebellions went, Dudley’s was fairly pitiful. He knew he couldn’t ignore what he’d seen out there among the eternal, unchanging constellations. Somewhat thankfully, he realized, he still had enough dignity left to make sure he didn’t take the easy burial option. Yet announcing the envelopment to the public would be the end of his own particular world. What others regarded as his essential meekness, he liked to think of as a caution that went with age. Similar to wisdom, really.

Old habits die hard, so he broke the problem down into stages, the way he always taught his students, and set about solving each one with as much logic as he could apply. Very simply, his overwhelming priority was to confirm the speed of envelopment. A wavefront of proof that was currently receding from Gralmond at the speed of light. And Gralmond was almost the farthest extent of the Commonwealth in this section of space. Almost, but not quite.

The Intersolar Commonwealth occupied a roughly spherical volume of space with Earth at the center, measuring four hundred light-years across. Gralmond was two hundred forty light-years from Earth, among the last of the second expansion phase planets to be settled. It didn’t require a great deal of calculation for Dudley to find that the next planet to witness the envelopment would be Tanyata, right on the edge of phase two space. Tanyata was even less developed than Gralmond—there was certainly no university yet—but a unisphere datasearch did find him a list of local amateur astronomers. There was one name on it.

Five months and three days after the evening he’d seen Dyson Alpha vanish, Dudley nervously waved good-bye to his wife as the Carlton pulled out of their driveway. She thought his trip to Tanyata was legitimate, sanctioned by the university. Even after eleven years of marriage, he didn’t have the courage to tell her the absolute truth. Or maybe it was that after five marriages he knew what to keep quiet about.

The Carlton drove him directly to the CST planetary station, on the other side of Leonida City from the university campus. Spring was just arriving, bringing a sprinkling of vivid green buds to the terrestrial saplings in the city’s parks. Even the full-grown native trees were responding to the longer, brighter days; their dark purple bark had acquired a new lustrous sheen as they prepared to unfurl their leaf awnings. Dudley watched the city’s residents from his seat: businesspeople striding about with purpose; parents being tolerant or exasperated with their kids; first-life adolescents milling about together outside coffeehouses and mall entrances, hopelessly gauche yet still managing to look like the most lethal gang members in human history. All of them so bright and normal. Dudley had chosen to settle here late in his second life because frontier planets always had an infectious air of expectation and hope; this was where new dreams really could take root and grow. And he’d done so little with that second life. His slightly desperate relocation here was an acknowledgment of that.

CST had opened their planetary station on Gralmond over twenty-five years ago. About the time Dudley was getting his colorful OCtattoo, in fact—an irony that hadn’t escaped him. The planet had done well for itself during its first quarter century of human history. Farmers had set their tractorbots and herds loose on the land. Urbanites brought prefab buildings that they lined up in neat grids and called cities in homage to the great metropolises they hoped would one day evolve from such humble beginnings. Factories were imported, riding in on the strong tide of investment money; hospitals, schools, theaters, and government offices multiplied fruitfully around them. Roads expanded out from the population center, sending exploratory tendrils across the continent. And as always, the trains came after them, bearing the greater load of commerce.

Dudley’s Carlton drove along the side of the Mersy rail route as he neared CST’s planetary station. A simple chain-link fence and a plastic safety barrier was all that separated the dual lane highway from the thick lines of carbon-bonded steel rails. The Mersy rail route was one of five major track lanes that had so far been laid out of the station. Gralmond’s population was rightly proud of them. Five in twenty-five years: a good sign of a healthy expanding economy. Three of the rail routes, including the Mersy, led away to vast industrial parks squatting on the outskirts of Leonida City, while the remaining two stretched out into the countryside, where forking again and again, they connected with the principal agricultural towns. Goods flowed in and out of the CST planetary station day and night, slowly increasing in quantity as the years progressed; circulating money, material, and machinery across fresh lands, advancing the human boundary month by month.

A big freight train grumbled alongside, going only slightly faster than the Carlton. Dudley looked over at the sound, seeing long olive-green wagons rolling along steadily, the sulfur-yellow lettering on their sides faded from age and sunlight. There must have been fifty of them linked together, all pulled along by a giant twenty-wheel engine. It was one of the GH7-class engines, he thought, though which particular marque he wasn’t sure; those brutes had been in use for nearly eighty years, a thirty-five-meter body filled with superconductor batteries, powering massive electric axle motors. Gralmond wouldn’t see anything bigger until the planet reached full industrialization status, in maybe another seventy years or so.

Already, such a monster trundling through the flourishing city seemed slightly incongruous. This district still contained a lot of the original prefab buildings, two- or three-story cubes of whitened aluminum with solar cell roofs. Redevelopment was hardly necessary on a world where the government gave land away to anyone who asked for it. Gralmond’s total population barely reached eighteen million, nobody was crowded here. The prefabs, however, remained as useful housing and commercial centers for the newest and poorest arrivals. But many city blocks of the shabby metal boxes had been torn down and replaced by new stone or glass-fronted buildings as the local economy bootstrapped itself upward. More common was the encroachment of drycoral, a plant originally found on Mecheria. New residents planted the genetically tailored kernels along the bases of their houses, carefully tending the long flat strands of spongy pumicelike stone that grew quickly up the walls, broadening out to form a sturdy organic shell around the entire structure, with simple pruning keeping the windows clear.

The passenger terminus was only a small part of the ten square kilometers that was the CST planetary station; most of the area was given over to marshaling yards and engineering works. At one end was the gateway itself, sheltered from the weather beneath a broad arching roof made from crystal and white concrete. Dudley could barely remember it from his arrival eleven years ago, not that it would have changed.

The Carlton drew up at the departures rank at the front of the terminal, then trundled off home as soon as he stepped out with his luggage. He walked into the station to find himself immersed in a throng of people who seemed to be going in every direction but the one he wanted. Even though it was relatively new, the concourse had an old-fashioned look to it: tall marble pillars held up a high glass roof; franchise stalls lurked in the cathedral-style archways; the short stairways between levels were implausibly wide, as though they led to some hidden palace; statues and sculptures occupied deep high alcoves, every surface covered in bird droppings. Big translucent holographic projections hung in the air, crimson and emerald signs that backed up the train timetable information for anyone who didn’t have an interface with the local network; little birds zipped through them continuously, hooting in puzzlement at the trail of sparkles their membranous wings whipped up.
