The attachment was four pages, scans, handwritten. The white wall in Vienna wasn't in frame; in the upper left corner of the paper there was a dent where her pencil had pressed. The subject line of the email was three characters: bring ears. Twenty-one days had turned into forty-two; the timestamp was 3:11 in the morning, her local time. Zhou Yan read it through twice, first pass eleven minutes, second pass forty-odd minutes.
The first two pages were derivation. The characters pressed small, the line spacing ruled out with a straightedge, and in the formulas there was one term she recognized—injection history, the quantity once audited, fourteen months, folded into a driving term and tucked into the seventh line. The seventh line was the thing that had shown only its name for over a year. The folding was on the lower half of page one: the injected contribution entered regardless of nationality, regardless of frequency band, merged into the initial value of the driving term as equivalent flux, and beside it a note: this step is the only hand put to the whole paper. In small characters at the foot of page two Ursula had added one line: the driving term's shape matches the tree-ring step from 993 to 1052, two-digit precision. Zhou Yan looked at that small line a long time. The step that had dropped away nine hundred-odd years ago and every kilowatt-hour of those forty-odd years had grown, on paper, into the same shape.
The third page held only five lines of results.
Line one: decomposition of the driving term's source, endogenous 97.6 percent, error plus or minus 4.1. Line two: injection history, 2.4 percent. Line three: with injection history set to zero, the global avalanche point moves back 470,000 years, error plus or minus 310,000. Line four: the seventh line positive definite, S monotonic, no solution that walks back exists. Line five: duration of the afterimage, not computable.
On the second pass, at the third page, the analogy assembled itself in her head. The seventh line had hung in the memo for over a year; Ursula herself called it the cosmetic, something painted on the equation's face, name given, value withheld. This night it was like that item on a physical-exam form which year after year read "no abnormality observed," and for the first time had produced a value. The value said three things: the drive to wake was essentially its own; whether humanity shouted or not, the difference was measured in hundreds of millennia; and the solution that walks back does not exist—the question of who pushed it awake had, in the mathematics, no road back.
She took a pencil and laid line three out: midpoint 470,000 years, the interval ran from 160,000 to 780,000. The width of the error was wider than the very difference that mattered. In other words, when this star would have woken on its own was less computable than the small account humanity owed it. She wrote this observation on scratch paper, read it over when done, and did not cross it out. It was the one thing she derived herself that night.
The fourth page had no derivation, two sentences. First: silence and escape are judged alike. Second: the file is timestamped, I take no questions, the numbers are all there, compute them yourselves.
She sat in the machine room until well past midnight. No reply—a reply could only contain questions, and not one question in her hands was worthy of this thing. She saved the four pages twice, one copy local, one in the 3t directory, turned off the light, and left. In the little room at the end of the corridor Lao Wu stayed in the dark, four shrimp pellets still on the tank bottom. She didn't turn on the light.
Tuesday she didn't go to the lab. This was the first day, counted later; at the time she simply didn't go. In the morning she connected the station's machines from her old laptop at home and ran the line owed from Monday night: 0.37, noted on the back of an envelope. The hiss still had a layer of cloth over it. In the afternoon she walked the third page's five lines through her head one at a time, the way a night shift walks its instruments, touching each line's switch once. At line five she stopped longest. Duration of the afterimage, not computable. In the star-carving budget defense, the retention time had been written as exceeding the current age of the universe by two orders of magnitude; that number she had signed. Now the two numbers sat face to face: on one side what the engineering had dared to write, on the other what the one who computed it refused to compute.
At ten that night, the seven-box meeting. She joined from home, camera off.
Three phone calls came after noon. One from the station's retired director, one from a PhD classmate she hadn't spoken to in ten years, one from a reporter; she took the first two, not the third. The old director asked what endogenous meant. She said: it means it has nothing to do with us. The old director was silent a few seconds on the other end, then said: then what have all these years been for. She said: for knowing. He said: that's fair too. The classmate asked only are you all right; she said all right; he said good, and hung up. The two calls together ran under five minutes.
Ursula spoke for four minutes. She read no derivation; she read the third page's five lines aloud, paused once at line four, pencil held in her hand, not turning it. Zhou Yan had watched that box for more than half a year; there had not been one second when that pencil was still. Ursula said: there is nothing that needs doing. That is the one benefit of this document. In those four minutes she said nothing else.
One box was the funding agency's observer, a new face, a name that had never been on any list. He asked: what should we activate. No one picked it up. His question hung on the shared screen for two minutes, and the box withdrew it itself. Mateo's box said three sentences, all of them orbits: after the budget deferral, the three departure windows had closed to two, the shortest one had forty-odd days left, drag past that and it's see-you-in-three-years. No one picked that up either, and the agenda moved on. Before the meeting broke up Kramer asked for the raw data, said he'd rerun it, and only accept it once he had. Ursula replied: the scan is the raw data. Kramer said what he wanted was the numbers. She replied: the numbers are all there, compute them yourselves.
Lu Weiming's box stayed dark the whole time, his name lit all evening, not one word said. The meeting ran from ten to ten nineteen, nineteen minutes, done. Afterward dozens of messages popped into the group; someone asked who had authorized the release, someone posted the download link, someone posted only a period. The period was Van der Merwe's; he had always given numbers, never names—this time he hadn't even given numbers. Zhou Yan answered none of them. She closed the window and went to boil water. Before it boiled her phone lit once: a private message from Lu Weiming, one line: this is everyone's illness, not your discovery. She stood at the stove and read the sentence twice; the water boiled, and she turned off the flame. That letter she later saved into 3t, filed with the two from the family of cluster nineteen, unanswered. Saving it, she understood the three characters in the email's subject line. The document took no questions; whoever opened it had to be the ear. Including her.
The document went public in the small hours. At 2:11 a directory appeared in the shared library, the four scanned pages posted as they stood—no explanation page, no signature, downloads unlimited. By eight in the morning the directory's download count was six digits. By noon the third page's five lines were in the news everywhere, most quoted as they stood; one outlet had turned lines one and two into a pie chart, and the 97.6 percent wedge was blue. In the evening someone moved the whole directory into the open paper repository, format untouched, the format field left blank; the administrator gave it a provisional number, filed after some April paper on asteroid mining. That day's headline came in only one version: it woke itself. The second day brought a second version: awake, and not ours to manage either. The authors of the two headlines, as ever, did not cite each other.
Kramer started running that very night. He keyed the numbers out of the scans into his own programs one by one, and when he reached the third page he said in the group: I'll take handwritten too. At two Wednesday morning his first version went up: decomposition reproduced, 97.4. Below it he added one line: your two-digit precision I can't reach; the third digit I won't accept. Ursula sent back one line: neither can I. Those were the only words she spoke after the document went public. Kramer asked for no more numbers.
Two pieces of footage came out over Wednesday. The first ran eleven seconds: someone from the Sleepkeepers carried the sign out of his house, the one printed last year—let them sleep—walked it to the corner, pushed it into a trash bin, turned, and left. Whoever filmed it sat in a car, no commentary. Later someone went to that corner: the bin was still there, the sign in the bin, the characters facing out. Sanitation didn't touch it; the next day it was still there. The second piece was the fifth clause of He Zhaoting's two-page proposal. Nobody forwarded the clause whole; what went around was the second half of the last sentence: at least we stopped once. Someone had subtitled it, seven languages, a black screen behind it, no music. The subtitler had checked the source and marked it in the reposts: a two-page proposal, 2021, the author holding no position. Zhou Yan called the proposal's scans out of 3t and turned to the fifth clause. Three lines in all, on why to stop, the half-sentence at the very end. Late the year before, when Old Tang brought her those two pages, she had read through that last line without stopping; today she stopped. She closed the file, and did not screenshot it for anyone. Old Tang called in the afternoon: reporters in Beijing had the guesthouse surrounded; the old man hadn't opened the door. Zhou Yan asked about the light. Old Tang said: the light was still on; someone at the guesthouse looked at two in the morning—still on. Old Tang added that among the reporters someone was holding up a phone, livestreaming the guesthouse gate, eighty thousand watching. Zhou Yan asked whether the old man knew. Old Tang said: if he knew, he wouldn't be the old man.
#OutsideMyWindow# surged again that day, the room count climbing back past four hundred seventy thousand. Hu Yisu resumed his stream in the afternoon, the camera aimed at a table this time: one laptop, one glass of water, nothing else. The chat asked what there was to watch. In the chat, someone also started scrolling that half-sentence, half a screen of it. He waited for the scrolling to run out before he spoke: that line isn't mine; an old man wrote it last year; if you want to scroll it, go scroll the original, don't scroll me. Then he said: nothing's changing out there. Here, it is. He stood the phone up on the table, sat down, and began revising the content committee's minutes. The minutes stopped at the committee's last meeting before it stopped meeting; item nine was the list question, and the minutes read: not discussed. He called that page up and sat facing it ten minutes; the chat sat with him ten minutes, nobody rushing. That night his viewership was back to seven digits; the chat gradually stopped asking and read the minutes along with him—people typed out page so-and-so, item so-and-so, like calling page numbers.
Eight o'clock, the video call. Outside Zhou Yao's window the sky was still light, the clothesline empty. The call ran four minutes twenty-two seconds. Zhou Yao brought up the document first; she had seen the news at school, and the class was passing that pie chart around. Zhou Yao said: I understood it. The blue piece is so big. The things you all did are the useless kind.
Zhou Yan said: mm.
Zhou Yao asked: what's the little piece that's left. Zhou Yan said: that's us. Zhou Yao went looking for that corner, found it, and said: so small. Zhou Yan said: mm.
Zhou Yao brought her face closer to the lens and said: I'll feel bad for her, just for a moment. She meant Zhou Yan, and used the third person; when she'd said it she waved a hand, as if filing the gesture too into the useless pile. She changed the subject: the art class assignment was settled, same question as before—leave only one sentence for the people who come after. She said: I've thought of mine, but I'm not saying it; said out loud, it wouldn't count as left. Zhou Yan said: all right. Zhou Yao said: and you don't ask either. Zhou Yan said: I won't ask. Zhou Yao added: Dad asked whether I'd thought of it; I didn't tell him either.
Just before hanging up, Zhou Yao asked suddenly: are you going to work tomorrow.
Zhou Yan said: going.
Zhou Yao said: then that's good. She said it very flat, and hung up.
When Zhou Yan got back to the kitchen, the dried noodles in the pot had clumped, four strands gone into one, the broth boiled dry. She stood at the stove and nudged at them; they wouldn't stir; she served them as they were and ate. Afterward she checked her mail. The duty sequence, on its overnight trial run, had computed the day's line and sent it over: line 160, 0.37. She sent back one word: received.
Whether Thursday was the second day or the third she couldn't have said herself. Not going to the lab had still resembled rest on day two; by day three it no longer did. In the morning Dr. Shen texted: the slot was hers until Wednesday, ten a.m.; held any longer, the system would dock his points. She replied: another day. After sending it she counted; that made the seventeenth. Dr. Shen sent back three characters: I'll keep it. Ten minutes later one more came: ear things don't heal themselves by being put off—you know that. She didn't reply again.
Day two hundred eleven of the hiss. She entered it in the ledger and added the second half: the cloth is a little thicker. She didn't know how many more days the description would hold; she logged it for now.
In the afternoon Eli sent a photograph. Lao Wu pressed against the tank wall, a caliper held beside the notch in his shell, the scale row flagged with his fingertip: two millimeters. One line below: no growth. She saved the photo and replied: and the food. Eli replied: five pellets, untouched. Then one more: changed the water. Sitting made her restless; she got up and went to the little shop, bought two bundles of dried noodles, and at the foot of her building found she'd forgotten the salt. She didn't go back. The shopkeeper knew her; at the register she asked: haven't seen you off to work these days. She said: resting. The shopkeeper said: resting's good—that work of yours grinds people down. Climbing the stairs with the two bundles, she thought: that lie would hold exactly one day. At home she set the noodles with the bundle already in the cabinet—three; she counted out how many days they would feed and got six. That arithmetic needed no thinking; she finished it anyway.
Before dark she did two things. The first: she called up the scan of that 2004 duty log page again and magnified it to the width of a stroke. The remark line's pending check was one pen, ink leaning blue, a hitch at the start of the strokes; the Noted underneath was another pen, ink leaning black, the strokes thin. Same page, two pens; how many days lay between them could not be told. She cropped a small patch of each, laid the two side by side in one file, and saved it into 3t. On the flyleaf of the folder holding that log page, the station office had written under investigation; the date after those two characters was three years old. The second: she opened the draft in her mailbox, the one called "Shoulder." The draft stood where it had the autumn of the year before, 2459483.793, its body a single paragraph, the first version of a reply meant for Lu Weiming, from when she still didn't know what to say. She read it start to finish, changed not one word, closed it. Before the window shut she glanced at the modified time. Unmoved.
In the evening the duty sequence sent line 161, 0.37. She replied received, and sat down at the window. In the new camera angle the poplar stood whole, two books wedged under its left side. She thought about the first thing tomorrow: filling in the page that had run three lines empty. All three were 0.37; the numbers were on the back of an envelope and in the mailbox, the notebook in the lab. The ledger hadn't broken—it was only being kept somewhere else.
At two-thirty in the night she woke once. She turned on the phone and went to look at that directory's download count: more than double what it had been before she slept, the curve on its way down, the slope gentle. She watched two minutes and laid the phone face-down on the nightstand. No light outside the window; whether the poplar was there, you couldn't have told at that hour. She lay back and counted the hiss, and counted her way into sleep without noticing.
Friday morning, seven forty, she walked into the lab. On the way she had stood a while at the foot of the building and looked up at her own window: the phone still propped on the sill, the livestream unbroken; the viewer count was out of her reach to see, and there was no need to see it. The canteen wasn't open; at the vending machine at the end of the corridor she bought a carton of milk and held it in her hand—cold. The corridor lights were still sound-activated: stamp a foot, one stretch lights. She spread the notebook open, turned to the three empty lines, and transcribed the three 0.37s one line at a time; done, she set three dots beside them. Her handwriting was clumsier than the duty sequence's print. She didn't trace it over.
The night-shift man in the machine room hadn't left yet—Ma Qiyuan, new at the station; everyone called him Xiao Ma. He was asleep at the desk, a few printed pages pinned under his hand. Zhou Yan refilled his hot water and, in passing, glanced at the top page: he had worked the set-to-zero item through himself, by hand, moving back from the avalanche point's median, and come out with 468,000 years. In the page header, one small line: night shift, nothing to do, having a try. A few of the numbers he had circled, the circle starting from the lower left, looping a turn and a half, closing at the digit's upper right. She knew that circling. On her own printouts, the circles she had once drawn around the shoulder had begun and ended exactly that way. She did not wake him to ask about it. She set the hot water by his hand and, in passing, smoothed the lower right corner of his page—the crease he'd slept into it ran straight across the line 468,000. Then she walked away.
At seven fifty-five she turned the notebook to a fresh page and drew the cells for line 162: four blanks, side by side. Today's value would have to wait for the ten o'clock batch to finish running before it was her turn to transcribe. Beside the cells she wrote 22:00, capped the pen, and pushed the notebook to its old place at the corner of the desk.
