Gregory Benford: Shipstar

Redwing had used the repair bots to inspect SunSeeker ’s hull soon after entering the Bowl system, and he privately agreed with Karl. In interstellar mode, their strong magnetic fields had kept the ship from the blizzard of neutral atoms and dust. SunSeeker was less effective dealing with erosions while it maneuvered at low thrust around the Bowl. The externals looked pitted and scarred now, and he wondered about whether the repair bots could spot flaws that could prove fatal in a personnel transfer. Or if the flexi would sustain pitting from random debris. A thousand questions nagged at him.

Redwing said, “We could try a fit with our dorsal hatch. We’d have to rig some kind of docking collar.”

This they liked. Redwing let them toss ideas around for a while as he tried to envision exactly how that configuration might work. Ayaan Ali had little to say, but he saw a quick widening of her eyes and nodded at her, holding up a hand to draw attention.

“I … have an idea,” she said quietly. “But we must work quickly.”

Beth watched the Bowl’s outer hull, a fast-forward world flittering by below the hard black of space. Even protrusions the size of skyscrapers were just passing gray blurs. In contrast, though the Bowl itself had a surface rotation speed in the range of many kilometers a second, the array of gas clouds and nearby suns hung still. Even high speeds on the interplanetary scale meant nothing to the solemn stars.

Their tubular craft traveled down the outside of the Bowl, hovering close on magnetically secured trap-rails. She watched enormous plains of gray steel and off-white ceramic flash by. Images jittered so fast, she could not tell what was important. A wall with crawling maggot robots, doing unknown labors. A sliding cascade of liquid metal fuming in high vacuum as it slid into jet-black chunks, then ivory cylinders, then shapely gray teardrops—all to descend into intricate new works, objects meant for mysterious use. All that went by in a stretched display she processed in a few seconds—an entire industrial process carried out in cold vacuum, far from the Bowl star’s intrusions. It seethed with robot motion. Fumes danced, billowed, and evaporated away in lacy blue streamers.

Now enormous tangled structures the size of mountains flowed by them. She could see lattice works and cup-shaped constructs but not what they did. It was difficult to keep perspective and their speed seemed to increase still, pressing her at an angle. She was sitting in a chair designed for some other being, one wider and taller. Windows on all sides showed landscapes flitting by, lit by starlight and occasional bright flares amid the odd buildings. From above her head came occasional clanking noises and whispery whistles—sounds of the mag-rail.

“All this industrial infrastructure,” Fred said quietly beside her. “Kept out of their living zone.”

“Ah, yes,” Beth said, not taking her eyes from the images flashing by in the big board window. “We hardly saw any cities before, either.”

“Sure, the Bowl’s land area is enormous, but then you realize that their whole mechanistic civilization is clinging to the outer skin. So they have twice the area we thought.”

Beth glanced upward into the “sky,” where the hull’s burnished metal gleamed beneath fitful lights. “And anyone who lives here, does so wrong way up. Centrifugal gravity pushes them away from the hull, so the Bowl is always over their heads. The stars are at their feet.” Beth laughed softly. “An upside-down world of its own.”

“Smart, really.” Fred was watching, too, his eyes darting at the spacious spectacle zooming past. “You can do your manufacturing and then throw your waste away in high vacuum.”

Beth shook herself; enough gawking. “Look, we’re in a cargo drone. We have to be ready in case we stop and get new passengers.”

“Relax. We’ll feel the deceleration, get ready.”

“At least we should search for food dispensers. This passenger compartment is for whoever’s accompanying the cargo—”

“Plants, yeah,” Fred said distantly, still distracted by the view. “Those finger snakes arranged to escort the plants, fit us in. Neat.”

Beth smiled. Fred had summed up days of negotiations. Their halting efforts had been beset by translation errors and mistakes. Even sharing a sort-of common language, a mix of Bird and Anglish, there were ambiguities that came from how different minds saw the universe. The snakes used wriggles and tiny movements of their outsized faces to convey meaning, and it took a while to even notice that. Words meant different things if a right-wriggle came with it, versus a left-wriggle. The snakes had similar troubles reading “primate face gestures” as they termed it.

Fred turned to her. “You’re worried about Tananareve.”

“I … yes.”

“You’re surprised I noticed.”

“Not really, I—”

“Look, I know what’s in my personnel file. I’m classic Asperger’s, yep. But I hope I make up for it by, well, my quirky ability to see how things work. Or that’s what the file says.”

To stall for time she asked, “How did you see your file?”

Fred was honestly surprised. She realized he did not actually know how to be dishonest, or at least without detection. “An easy hack.”

“Well … yes. I read everybody’s file before we left SunSeeker. Standard field-prep method.”

“So I should overlook how you fret about us, especially Tananareve.”

“She’s not really recovered, and I should’ve noticed she didn’t get in here with us.”

Fred gave her an awkward smile. “Look, the place was confusing and we didn’t have any time. She wandered off. There were the finger snakes making a racket and shooting questions at us.” A sigh. “Anyway, put it aside. We’ve got the boarding problem coming up.”

She sighed. “Right, of course.” So much for Asperger’s patients not picking up on social signals. What had that training program said? “Cognitive behavioral therapy can improve stress management relating to anxiety.” Yet Fred seems calmer than the rest of us.…

Fred pressed on. “The snakes say we’re due for a stop about where SunSeeker could rendezvous with us. But we have to come out at high speed, so they have to match us. But—”

“Nothing like pressure suits aboard,” Lau Pin said. “The snakes say they can’t make anything like that, not in time.”

He and Mayra had come up, carrying a bowl of what looked like gruel. Mayra scooped some out with a spoon, tasted it. “Bland, but no harm on my bioregister. This comes out of a dispenser in the next car.”

So they all fell to eating. Beth was hungry, so the lack of taste in the muddy mixture of carbs and sugars didn’t stop her. She was thinking, anyway. Silence, except when two snakes came by and chattered in their high, fluting voices. Beth ignored them while Mayra carried on a halting conversation with the aliens. Intelligent aliens, the goal of centuries of searching, and I don’t have time for them.…

Her hand stopped with her spoon in midair as she stared into the distance. Slowly she turned to Mayra. “Ask them if we can disconnect this car from the track,” she said.

The big problem was hard to sense when you were blithely standing in fractional gravity and not paying attention to the sky. Here on the mag-train, that sky was filled with stars, and it took an hour or two to notice that they were moving. As she thought, Beth watched a bright star move off the window where she sat. The Bowl rotated in thirty-two hours, so the night sky seemed to move a bit slower than it did on Earth. She recalled how, in elementary school, she had been amazed that while sitting at her desk she was really whizzing around at well over a thousand kilometers an hour. The Earth’s rotation did that, and its orbit moved her at thirty kilometers a second, too. Now she was sitting in a fast train car and also moving with the Bowl’s rotation, hundreds of kilometers a second. Leaving the Bowl meant launching into space at that huge velocity.
