Ursula's four lines hung in the group into the next day, and still no one picked them up. Zhou Yan came into the machine room at nine on Tuesday as always and first computed line one hundred five: 0.37. She copied it onto paper and set it beside the line before it for a while; nothing came of looking. The hiss, day one hundred sixty-seven, pitch unmoved; in the corner of the notebook she made the usual entry. The paper records stood at eleven thousand one hundred ninety. She filled in the day's cell and closed the folder.
The letter came in the afternoon, on a red header, from the Long Night secretariat, signed by the newly founded Standing Legacy Committee: three proposals in review—R-1, deep-space broadcast, code name Echo; R-2, closed ark, code name Seeds; R-3, star-catalog etching, no code name yet. At the foot, one line naming her to appear and testify, the subject also one line: synchronization index and sky-noise trend over the Silence. The date was set for Thursday.
Hu Yisu printed out the three summaries and spread them on the desk and read for ten minutes. He said: broadcast, ark, gravestone. The first two are keep shouting and keep running. The third is starting to write the will.
He turned up R-3's budget page and pointed it out to her. The deflection array running one year at full power draws four percent of last year's global electricity. Carving a gravestone for the dead, on a grid that belongs to the living. He pushed the page aside. He said: I'm against it. I'm saying so here first; Thursday I'll go say it there too.
She said: you weren't named.
He said: I'm coming with you. You're carrying testimony, aren't you—I'll carry it for you. He paused. One more thing. If it were me deciding, I wouldn't put up a stone at all. What's wrong with being awake? People who are awake don't put up stones.
She didn't take that one up. She read R-3's claim through once more. She recognized that claim: the waking depends on an active plasma substrate; cooled degenerate matter lies outside the substrate. Below it, the target: the white dwarf GY-1402, its number in the Gaia catalogue, surface temperature forty-one hundred kelvin, crystallized shell formed a billion years ago. The reasons for choosing it ran to four: cooled all the way through, fully crystallized; rotation period one hundred thirty-seven days, so the etching won't be smeared by spin; no companion, a clean orbit; magnetic field too weak to measure, so the grooves won't be stirred up by the magnetosphere. Under each reason stood a column of numbers, and the shortest column ran eleven lines.
Wednesday night she prepared her testimony twice. The first time she prepared words; she wrote three lines and struck out three lines—words all carry a direction, and a direction means some people claim them and some don't. The second time she prepared numbers: one table, one spectrum, one inversion value. Hu Yisu watched her pick from the side and said: you don't plan to say a single thing? She said: the numbers stand on their own. Hu Yisu said: and if someone asks what you think. She said: if they ask, I'll hand over a second table. He didn't press again. He squared the three pages she had picked into order and clipped them together, the way you book observing time for an observation.
The review was Thursday, by video, twenty-three seats on the committee. Speaking order had been drawn by lot the day before: R-1 first, R-2 in the middle, R-3 last. Amina chaired; she read the opening from the script for fourteen minutes without one wrong character. Read, close the script, wait three seconds: the reports, please.
R-1 went first. The presenter was a retired deep-space tracking director, sixty-odd, his voice raspy. He had just one core sentence: the 1968 tapes prove we were always loud enough—so we go on being loud. He wanted a transmission array on the far side of the Moon, two hundred times the combined power of every existing deep-space uplink, cycling the same content for a hundred years. From the floor someone asked, transmit what. Content committee to be convened separately, he said. Someone asked, to whom. He paused, and said: to every place still listening.
Her turn to testify came next. She had brought one sheet of paper. The hundred-day S table, one hundred four lines, a scan; the spectrum from the fourteenth day after resumption, one hundred ninety-one lines; the tapes' inversion, forty times. She put the three on screen and said: day one hundred of the Silence, 0.37. Day one hundred four, 0.37. And sat down. No one asked whether she thought the broadcast would work. One seat read out the two headlines from two weeks before—"we were never quiet," "a hundred years of noise didn't wake it"—and asked which one this data supported. She said: neither. What the data supports is day one hundred four, 0.37. The director switched off his microphone.
R-2's presenter was an engineer thirty years in closed ecosystems; the first photograph he showed was a paddy of rice growing inside a module. The ark was the thickest file of the three: self-sustaining habitat, generational crew, destination undecided, power a fusion reactor plus a lightsail. The questions from the floor were very tidy: how long does the fuel last. A thousand years, he said. And after a thousand years. After a thousand years is not this proposal's problem, he said. Someone asked him where to. He pointed at a star in the corner of the slide, said a name, and added: the sun there is stable. At once someone pointed out that that star was among the Gaia catalogue's one thousand forty-two. He said he knew. The floor stayed quiet longer than it had before. Hu Yisu caught up with her in the break area and said one sentence: move it inside the body. She understood him—wherever you go, a sail needs light, light comes from stars, and stars are in the substrate.
R-3 was Mateo's to present. His slides carried no photographs; all of them were diagrams. The impactors were nickel-iron bodies chosen from near-Earth asteroids, two-hundred-ton class; the deflection array would change their orbits batch by batch and bring them onto the target one after another inside the window. The grooves were designed to a depth of two hundred thirty meters, the content encoded in the sequence of impacts: the moment, the interval, the yield—that is the alphabet. Someone asked how many grooves. The engineering, he said, is sized for thirty impactors: seventeen calibration bodies, thirteen carrying content; the number of grooves waits on the content. Someone asked where two hundred thirty meters came from. Computed, he said, from the crystallized shell's cooling age and the recrystallization rate—neither number is clean; the budget carries a hundred meters of error. When he reached "retention time exceeds the current age of the universe by two orders of magnitude," someone cut in and asked what made that number believable. He said: that isn't the point. The point is the first clause—that star is cooled through, and what has cooled through is not its department to govern.
That sentence was Ursula's. Hu Yisu had dug it out the night before from page seven of her public lecture notes; the original reads cooled degenerate matter does not participate, with no derivation underneath. For the committee to cite it, the rule was confirmation by the person herself; but she was computing line seven—twenty-one days agreed on, no asking in between. The citation column stayed blank at the end; the note beside it read: pending signature.
Zhou Yan sat in the observers' seats and passed the claim through her head once. The substrate is the flesh; the crystallized shell is the bone. A dream can move flesh; it cannot move bone. She thought of the three notches on Lao Wu's shell—the shell isn't the crayfish's department either. She pinched the thought off and kept only the numbers.
The vote came at dusk. R-3, fourteen votes; R-1, three; R-2, two; abstentions, four. Amina read the approval from the script, the formal name of R-3: the Star-Catalog Etching Project. Reading it, she lifted her head and added four characters: notify all states at once. Those four characters were praised for a long time afterward—the Secretary-General has resolve. Only the reporters who had copies of the script knew the four characters were printed on the last page; she had read them off, and afterward tapped the page once with her pen point.
The chief engineer's appointment passed by acclamation: Mateo Ibarra. Someone asked him why he was taking it. His camera was on, the white wall of Las Campanas behind him. He said: at eight years old I learned one thing. Paper goes away. This star doesn't. The first question he asked after that was the array's construction schedule; the second was whose job the impact-window orbit computation was. No one asked what he meant to carve. He didn't ask either.
Forty minutes after the session, Kramer's email arrived, asking for R-3's complete orbital data. Mateo replied: there is no data yet, only a decision. Kramer wrote back: then give me the decision. Mateo forwarded the ballot as it stood, with one line attached: the checksum is in the footer.
Saturday morning she computed line one hundred ten first. 0.37. By her old rule she reran it exactly as it was; 0.37 again. Day one hundred ten, line one hundred ten, two numbers written side by side; she couldn't have said which was harder. She entered the value on the paper page and set a pencil dot beside it. The group stayed as quiet as ever; she didn't send it. The paper records stood at eleven thousand seven hundred ninety.
Eight in the evening, the video call. Zhou Yao had seen the news at school; her class was passing around a star that was going to be carved with writing. Zhou Yao lay over the desk, her face close to the camera, and asked: does it hurt, the star?
Zhou Yan thought a moment and said: hurting takes nerves. Its nerves aren't in that.
Zhou Yao said: so it doesn't know while it's being carved?
It doesn't know.
Zhou Yao set her chin on her arms, thought a while, and said: good. And asked: then does it know when we've finished?
Zhou Yan said: the part of it that knows can't reach the bone.
Zhou Yao said: oh. The way she said it wasn't like understanding; it was like putting the matter away. Before hanging up she held her sketchbook up and turned a page: a person with closed eyes, a hand resting on an open book. She said she'd drawn three this week and picked one. Zhou Yan said: I saw it. Very good. Zhou Yao said: the teacher set an assignment—if you could leave one sentence to the people after us, what would it be. I haven't thought of it yet. Zhou Yan said: no hurry. Zhou Yao said: mm, the whole class hasn't thought of it yet.
The group's silence took on a shape this week. Someone left; before leaving, they changed their display name to "forget it." No one came in. Hu Yisu counted: seven days, zero messages. He wrote that number on paper too, on the same page as the S values.
The second week's days passed like checking clocks. The project approval ran in every country's wire copy, and this time the headlines came in only one kind: humanity begins writing its will. The second kind of headline took three more days: it's the living who write wills. The two kinds' writers never cited each other.
The array's survey team went out into the gobi and stopped by the station for fuel on the way back. Eli pointed them the road; coming in he told Zhou Yan that in his youth he'd pulled cable through that country, and underneath it was one solid slab of granite—a nail wouldn't go in. A place nails won't go into is a fine place to put an array, he said; the things won't wander on their own. When the fueling trucks left he stood in the doorway watching a while, and said: this time it's really something being done.
She sat in on the content committee's first conference call for forty minutes. The first three items were format: encoding and error correction, time base, coordinate base—ten minutes each, gone through smoothly. The fourth item had barely reached the word content when the American spoke up first: the constants—mathematical and physical constants go at the very front; every civilization knows them. The Russian proposed the genome: everyone has the constants; the genome there's only one copy of. Hu Yisu waited until the two sides finished, and asked one question: where does the list go. The chair said the list item was scheduled later. Hu Yisu said: I only want to know whether it goes in front of the genome or behind it. The meeting ran twenty minutes over, no conclusion; before it broke up, the minutes-reader read out the next meeting's date, got it wrong, and corrected himself.
Zhou Yan did her one line of S each day, all 0.37, with one 0.36 wedged among them. As always she reran every tenth line and only recorded the rest. The paper records reached thirteen thousand five hundred ninety; two thousand ten left. Lao Wu hadn't molted. Water twenty degrees; five shrimp pellets; when he reached the third he stopped moving, and she left the other two on the stone and switched off the light.
The second letter from the cluster-nineteen family came Wednesday. Squared exercise paper, fountain pen again. Two lines: we played the tape through last night; it sounds the same as what I heard as a child outside the machine room. Thank you. Nothing besides. She photographed the letter into 3t, set it with the first one, and did not write back—there was nothing left to write back; the thing had been said out.
Old Tang telephoned, saying He Zhaoting had asked him to carry a message. The Sleepkeepers had been loud about the bone carving these past days—calling it the surrender project, saying the hundred days of silence had been silent for nothing. Zhou Yan asked what He Zhaoting had said. Old Tang said, the old man's answer was one line: that thing isn't loud. Zhou Yan asked whether he'd read the communiqué. Old Tang said he had, read it and set it down, and that was all. Old Tang paused, and added: the guesthouse says the old man's light was still on—two in the morning, and it wasn't off.
Hu Yisu filed his application to join the content committee. When the roster was posted he stood last, the duty column reading advisory member. He told Zhou Yan: I'm going in to raise the objection. Whoever proposes the scheme pays the power bill; somebody has to be in the room doing the arithmetic. She said fine. On his way out he asked one more: tell me—when the grooves on that star are really there, who is it that goes to look? She said she didn't know. He said: neither do I. That sentence he didn't lace with anything.
Saturday night Mateo posted four lines in the group. That day she had computed through line one hundred twenty-two, 0.37; the hiss, day one hundred eighty-five. The window is computed. The first batch of impactors has three departure windows; a departure decision must be made inside fourteen months, or everything slips three years. After departure, the arrival windows converge into one: eleven days. He sent it to her separately as well, with one line attached: check the dates for me.
She went through his three pages of orbital tables. The three departure windows ran eleven days, nine days, and five days, the latest of them starting no later than March of next year; the arrival window opens on Julian date 2461152 and closes on 2461162. Thirty impactors, nickel-iron, two-hundred-ton class: seventeen calibration, thirteen with content; the first seven calibration bodies land first, their footpoints strung into a baseline, and the content bodies follow the sequence from the eighth on. She counted backward off the ephemeris, from 2461152 back to today: one thousand four hundred sixty-one days; four years to the day. She wrote back: checked; the dates are right. He sent back two words: thank you. After a while, one more: three departure windows—I'm betting on the shortest. She asked why. He said: short decisions save time.
She opened the paper notebook to the page with 21 written on it. Three days now she hadn't touched that page; under 21, two days were left unstruck. She rested the pen on those two characters a moment, turned the page over, and in the blank on the back wrote 2461152. Looked at it a while, and after it added a two-character note: first strike.
