Peter Watts - Firefall

Valerie began to convulse. She tried to arch her back; something stopped her. Her fingers fluttered, her arms shook against the padded arms of the chair; for the first time Brüks realized that she was strapped into the thing.

Fireworks exploded across her brain. Her heart, so immutably stable until now, threw jagged spikes onto the time series and shut down completely. The body paused for a moment in midconvulsion, frozen in bone-breaking tetany for an endless moment; then the chair’s defibrillators kicked in and it resumed dancing to the rhythm of new voltage.

“Thirty-five total degrees of arc,” the invisible voice reported calmly. “Three-point-five degrees axial. Rep twenty-three, oh-nine-nineteen.” The recording ended.

Brüks let out his breath.

“Has to be real,” Sengupta grunted.

“What?”

“Horizon’s not real . It’s, it’s between . They don’t glitch on hypotheticals.”

He thought he understood: vampires were immune to horizons. No matter how flat, no matter how perfect, they were zero thickness. You couldn’t build a cross with a horizon, not one that stopped Valerie and her buddies at least: for that, you’d need something with depth .

“Really hard to get this,” Sengupta remarked. “The explosion scrambled the records.”

“Explosion?”

“Simon Fraser.”

Realist attack, he remembered. A couple of months before he’d gone on sabbatical; the bomb had taken out a lab working on spindle emulation. He hadn’t heard anything about the vamp program being targeted, though.

“There would’ve been backups,” he guessed.

“For the footage sure. But how do you know it’s her, huh? You never see her face. The embeds just give a subject code. Gait recognition not so great when your target’s tied down.”

“The voice,” Brüks said.

“That’s what I used. Now try trawling the cloud with a random voice sample, no stress data, no contextuals.” Sengupta jerked her chin. “Like I said. Hard. But I got it now it’s getting easier all the time.”

“They tortured her,” Brüks said softly. We tortured her . “Does—does Jim know about this?”

Sengupta barked out a humorless laugh. “I wouldn’t tell that asshole what time zone he was in.”

You don’t have to do this, Brüks thought. You don’t have to work so hard turning all that pain into anger. You could be free, Rakshi. Fifteen-minute tweak and they’d cut the grief right out of you, the same way they wired in the love. Twenty-five minutes and you’d forget you’d ever been in pain.

But you don’t want to forget, do you? You want the grief. You need it. Your wife’s dead, she’ll be dead forever but you can’t accept that, you’re clinging to Moore’s Law like a life jacket in a hurricane. Maybe they can’t bring her back now but maybe in five years, maybe ten, and in the meantime you’ll make do on hope and hate even if you haven’t figured out where they belong.

He closed his eyes while she smoldered at his side.

God help me when you do.

Back in the Hub, she’d stripped the sun naked. It seethed and roiled overhead, close enough to touch (which he did, just for the surrealistic hell of it: a gentle push off the grille, a weightless drift, and Daniel Brüks could kiss the sky). But the curve of its edge was as clean and sharp as if razored: no flares, no prominences, no great gouts of plasma to dwarf a dozen Jupiters and fuck with Earthly broadcasts.

“Where’s the corona?” he asked, thinking: Filters .

“Ha that’s not the sun that’s the sun side .”

Of Icarus, she meant: the sun and Icarus face-to-face, the light of one bouncing off the disk of the other into the eye of some remote camera, massively shielded, floating out front on the breath of a trillion hydrogen bombs.

“Perfect reflector if you crank it up high enough,” Sengupta said. “Won’t do much for the rads but if you’re talking about thermal and visible spectrum I could turn this place into the coldest spot from here to the Oort.”

“Wow,” Brüks said.

“That’s nothing look at this .”

The sun—the sun’s reflection—darkened by degrees. Those brilliant writhing coruscations began to dim: the sunspots, the weather systems, the looping cyclones of magnetic force began to fade from sight, sink into some colder cosmic background. Within moments the sun was a pale phantom on a dark mirror.

Something else was there, though: other currents, convecting like a pot of molten glass brought to a rolling boil. Liquid mass upwelled near the center of the disk, swirled outward in an endless bloom of turbulent curlicues, cooled and slowed and stagnated near the darker perimeter. It was as though the solar photosphere had been stripped away to reveal some other, completely separate weather system churning beneath.

Except, Brüks realized after a moment, he wasn’t looking at the sun at all, not even in reflection. This was—

“That’s Icarus, ” he murmured. A great convex solar cell a hundred kilometers across: transparent or opaque, solid or liquid, its optical properties slaved to the whims of a glorified thermostat and Rakshi Sengupta’s little finger. Darker now, just a few degrees closer to blackbody status, the convection currents swirled ever faster as it worked to dump the excess heat.

Off in some distant corner, an alarm woke with a soft beeping.

“Um…,” Brüks began.

“Don’t worry roach just throttling up a bit to build some extra ergs don’t want Earth to fall below quota do you?”

The beeping continued, increasingly urgent. Insistent little tags began flashing near the bottom of the display, albedo falling, absorbance and ΔT on the rise.

“I thought we’d already tanked up.” It had been the final phase of the reconstruction: the last of the Bicams had stowed their tools and abandoned the Crown ’s refitted hull for a group hug around Portia , twelve hours before. (Apparently their brains fell out of contact beyond some limited range.)

“Got some need more that’s a lot of mass we gotta get out from under.”

Brüks couldn’t take his eyes off the sunside view: like looking down at a blooming mushroom cloud in the wake of an airburst. He knew it was only imagination but the Hub felt— warmer …​

He bit his lip. “Aren’t we overheating? Those tags—”

“More product takes more power right? Basic physics.”

“Not that much more.” Surely she hadn’t dialed down the reflectivity this far the last time, surely this was just—

“Want to double-check my numbers roach? Don’t trust my math think you can do better?”

—showing off…​

The sunside sparked and vanished from the dome: NO SIGNAL pulsed above the warning icons left behind.

“ Shit, ” Sengupta spat. “Stupid cambot melted.”

“I’m impressed,” Brüks said quietly. “Now will you please just dial it back a—”

“Quit fucking around, Rak.” Lianna ricocheted up from the southern hemisphere, bounced off the Tropic of Cancer and arced toward the forward hatchway. “We’ve got more important things to do right now.”

“Yeah right more important than putting charge in the tank.” But her fingers twitched in the air, and the alarms dimmed a little. “Like what?”

Lianna spun around a handhold and planted herself on the arctic circle. “Like Oldschool’s slime mold. It’s talking to us.” And disappeared through magnetic north.

TALKING WAS GENEROUS: the images that had begun crawling across Portia ’s skin were crude, chunky things, primitive mosaics built from pixels a centimeter on a side. There was no window per se, no distinct bounded area within which relevant information was neatly displayed. The mosaics simply faded into existence and out again, the oily gray of default epidermis stippling gradually into a roughly circular area of increasing contrast, a black-and-white scratchpad reminiscent of a crossword puzzle. Brüks’s secular circuitry couldn’t discern any pattern there.
