Seveneves: A Novel Read online

  In academic settings, such as when he was keynoting astronomical meetings and writing papers, he was, of course, Dr. Harris.

  The moon blew up while he was attending a fund-raising reception in the courtyard of the Caltech Athenaeum. At the beginning of the evening it was a fiercely cold bluish-white disk rising above the Chino Hills. Lay observers would fancy it a good night for moon watching, at least by Southern California standards, but Dr. Harris’s professional eye saw a thin border of fuzz around its rim and knew that aiming a telescope at it would be pointless. At least if the objective were to do science. Public relations was another matter; operating more in his Doc Dubois persona, he occasionally organized star parties where amateur astronomers would set their telescopes up in Eaton Canyon Park and aim them at crowd-pleasing targets such as the moon, the rings of Saturn, and the moons of Jupiter. Tonight would be a fine night for that.

  But that wasn’t what he was doing. He was drinking good red wine with rich persons, mostly from the tech industry, and being Doc Dubois, the affable science popularizer of television and of four million Twitter followers. Doc Dubois knew how to size up his audience. He knew that self-made tech zillionaires liked to argue, that Pasadena aristocracy didn’t, and that society wives liked to be lectured to, as long as the lectures were brief and funny. And he knew that his job was to charm these people, nothing more, so that they could later be handed off to professional fund-raisers.

  He was going back to the bar for another glass of the pinot noir, fully in the Doc Dubois persona, slapping shoulders and bumping fists and exchanging grins, when a man gasped. Everyone looked at him. Doob was afraid that the poor guy had been struck by a stray bullet or something. He was frozen, poised on one leg, gazing up. A woman followed his gaze and screamed.

  And Doob became one of perhaps a few million people around the dark half of the planet all looking up into the sky, in a state of shock so profound as to shut off the parts of the brain responsible for higher functions like talking. His first thought, given that they were in Greater Los Angeles, was that they were looking at a black projection screen that had been stealthily hoisted into the air above the neighboring property, and were seeing a Hollywood special effect thrown onto it by a concealed projector. No one had informed him that any such stunt was under way, but perhaps it was some incredibly bizarre fund-raising gambit, or part of a movie production.

  When he came to his senses, he was aware that a large number of telephones were singing their little electronic songs. Including his. The birth cry of a new age.

  IVY XIAO WAS IN OVERALL COMMAND OF IZZY AND SPENT ALMOST all of her time in the torus, partly because her office was there and partly because she was more susceptible to space sickness than she liked to admit. That physical separation—Ivy back in the torus, Dinah up in the forward end, close to Amalthea—was symbolic, in many people’s minds, of a difference between them that didn’t really exist. Other contrasts were obvious enough, beginning with the physical: Ivy was four inches taller, with long black hair that she kept under control usually by braiding it and trapping the braid under the collar of her jumpsuit. She had the build of a volleyball player. Raised in Los Angeles, the only child of high-strung parents, Ivy had SATed, science faired, and spiked her way to Annapolis, then followed that up with a Ph.D. in applied physics from Princeton. Only then had the navy demanded the years of service that she owed it in return for her tuition. After learning how to pilot helicopters, she had spent most of that time in the astronaut program, in whose ranks she had risen quickly. Unlike most astronauts, who were mission specialists—scientists or engineers carrying out specific tasks after the launch vehicle had reached orbit—Ivy, with her training as a pilot, was a flight specialist as well, meaning that she knew how to fly rockets. The days of the Space Shuttle were long over, so there was no need to joystick a winged vehicle back to a runway. But docking and maneuvering spacecraft in orbit was a good clean match for someone with the motor control of a chopper pilot and the mathematical mind of a physicist.

  The pedigree was intimidating, even off-putting to people who were impressed by such things. Dinah, who wasn’t, cared little one way or the other. Her informal behavior toward Ivy was interpreted by some observers as disrespectful. Two very different women in conflict with each other made for a more dramatic story than what was actually true. They were continually bemused by the efforts made by Izzy personnel, and their handlers on the ground, to heal the nonexistent rift between them. Or, what was a lot less funny, to exploit it in the pursuit of byzantine political schemes.

  Four hours after the moon blew up, Dinah and Ivy and the other ten crew members of the International Space Station had a meeting in the Banana, which was what they called the longest uninterrupted section in the spinning torus. Most of the torus was chopped up into segments short enough that the brain could talk the eye into believing that the floor was flat and that gravity always pointed in the same direction. But the Banana was long enough to make it obvious that the floor was in fact curved through about fifty degrees of arc from one end to the other. “Gravity” at one end of it was aimed in a different direction from that at the other end. Accordingly, the long conference table that ran down its length was curved too. People entering into one end looked “uphill” to the opposite end, but experienced no sensation of climbing as they moved toward it. New arrivals tended to expect that anything placed elsewhere on the table would roll and slide down toward them.

  The walls were pale yellow. The usual collection of malfunctioning audiovisual equipment purported to show live video streams of people on the ground, in theory enabling them to teleconference with colleagues in Houston, Baikonur, or Washington.

  When the meeting began at A+0.0.4 (zero years, zero days, and four hours since the Agent had acted upon the moon), nothing was working, and so the occupants of Izzy had a few minutes to talk among themselves while Frank Casper and Jibran Haroun wiggled connectors, typed commands into computers, and rebooted everything. Relatively new arrivals to Izzy, Frank and Jibran had made the mistake of letting on that they were good at that sort of thing, so they always got saddled with it. Both of them were more comfortable with it anyway than with making chitchat.

  “Primordial singularity” were the first words Dinah heard upon gliding into the room. Gravity here was only one-tenth of that on Earth, and “walking” wasn’t the right word for how people moved around—it was halfway between that and flying, a sort of long, bounding gait.

  The words had been spoken by Konrad Barth, a German astronomer. It was clear from how the others reacted that Ivy, who was sitting directly across the table from him, was the only other person in the Banana who had the faintest idea what he was talking about.

  “And that is?” Dinah asked, since that sort of thing had become her role. Others tended to be so worshipful of Ivy, or so reluctant to show ignorance, that they wouldn’t ask.

  “A small black hole.”

  “Why ‘primordial’?”

  “Most black holes are formed when stars collapse,” Ivy said. “But there’s a theory that some of them were created shortly after the Big Bang. The universe was lumpy. Some of the lumps might have been dense enough to undergo gravitational collapse. They could form black holes that instead of weighing what a star weighs could be a lot smaller.”

  “How small?”

  “I don’t think there’s a lower limit. But the point is that one of them could zip through space invisibly and punch all the way through a planet and out the other side. There used to be a theory that the Tunguska event was caused by one, but it’s been disproved.”

  Dinah knew about that, because her dad liked to talk about it: a huge explosion in Siberia, a hundred years ago, that had knocked down millions of trees out in the middle of nowhere.

  “That was a big deal,” Dinah said, “but not enough to blow up the moon.”

  “To blow up the moon would take a bigger one, going faster,” Ivy said. “Look, it’s just a hypothesis.”

  “But it’s gone now?”

  “It would be long gone now. Like a bullet through an apple.”

  It struck Dinah as odd that they were talking about such an event so matter-of-factly. But there was no other way to address it. Emotions were not large enough to encompass such a thing. Besides, it was just a visual effect so far, like something seen in a movie with the sound turned off.

  “Is it going to affect the tides?” asked Lina Ferreira. As a marine biologist, Lina would naturally be somewhat concerned about the tides. “Since those are caused by the moon’s gravity?”

  “And by the sun’s,” Ivy added with a nod and a little smile. Which was why she was in charge of Izzy and Dinah wasn’t. She was willing to correct a Ph.D. marine biologist in front of a roomful of people, but she could carry it off in a way that didn’t sting. “But the answer is, probably surprisingly little. The moon’s mass is still all there, close to where it was before. It’s just spread out a little. But the pieces still have the same collective center of gravity, still in the same orbit as the moon had before. Your tide tables will still pretty much work.”

  Dinah’s facial expression was blank, but she was enjoying Ivy’s ability to talk about science with a kind of little-nerd-girl sense of wonder even in spite of the disturbing subject matter. This was why Ivy always got the media interviews, while Dinah had to be dragged out of her den of robots and told, over and over again, to smile. The tone of voice was the giveaway; when Ivy was giving orders or reading PowerPoint slides, she went clipped and military, but when she talked about science her face opened up and her voice went into a vaguely Mandarin singsongy lilt.

  “Where are you getting all this?” Dinah asked, drawing startled or disapproving glances from a few who worried that she was being t
oo brusque with the boss. “It’s only been, what, four hours?”

  “There’s a lot of noisy comment thread traffic, as you’d expect, and a few ad hoc email lists sort of congealing out of that,” Ivy explained.

  A blue screen appeared on the lightweight monitor stretched above one end of the long table, and was replaced by a NASA logo. “Okay, got it,” muttered Jibran, who made a sideways bound toward a chair.

  Then they were looking at the familiar environs of the ISS Flight Control Room, which was at Johnson Space Center in Houston. The director of mission operations was sitting in front of the camera stroking his iPad. He didn’t seem to be aware that the camera was on. A few moments later they heard a door open off camera. The DMO, who was ex-military, stood up out of habit. He reached out and shook hands with a woman who entered from stage right: NASA’s deputy administrator, the number two person in the whole org chart and a rare sight at such meetings. She was a retired astronaut named Aurelia Mackey, dressed for business in the environment of D.C., where she spent most of her time.

  “Are we on?” she asked someone off camera.

  “Yes,” said several people in the Banana.

  Aurelia looked a little startled by that. Both she and the DMO were looking a little stunned to begin with, of course.

  “How are you all today?” Aurelia said, in an absolutely rote, businesslike voice, as if nothing had happened. Running on autopilot while her brain caught up with events.

  “Fine,” said some people in the Banana, mixed in with a few nervous chuckles.

  “I’m sure you are all aware of the event.”

  “We have a good view of it,” Dinah said. Ivy shot her a warning look.

  “Of course you do,” Aurelia admitted. “I would love to have an extended conversation with you all about what you have seen and what you are experiencing. But this is going to have to be brief. Robert?”

  The DMO peeled his eyes off the iPad and sat forward in his chair. “We’re expecting an increase in the number of rocks floating around up there.” He meant loose chunks of the moon. “Not huge because most will be gravitationally bound. But some may have escaped. So other missions are suspended while you batten down the hatches. Make preparations for impacts.”

  Everyone in the Banana listened silently, thinking about what that would mean for them. They would tighten precautions, dividing Izzy up into separate compartments so that damage to one wouldn’t suck the air from all. They would review procedures. Lina’s biology experiments might take a hit. Dinah’s robots would enjoy a holiday.

  Aurelia spoke into the camera. “All spaceflight operations are suspended until further notice. No one is coming up and no one is going down.”

  Everyone in the Banana looked at Ivy.

  AS SOON AS THEY GOT INTO IVY’S TINY OFFICE, WHERE SHE FELT IT was okay to let tears come into her eyes, they slipped into their Q code.

  Q codes were ham radio slang. Dinah had learned them from Rufus. They were three-letter combinations, beginning with Q. To save time in Morse code transmissions, they were substituted for frequently used phrases such as “Would you like me to change to a different frequency?”

  Dinah and Ivy’s Q codes didn’t actually begin with Q. But some of them were three-letter combinations.

  Uppity Little Shitkicker was a name that had been hung on Dinah when she had first arrived at private school and, during a soccer scrimmage, intercepted a pass meant for a girl from New York.

  Straight Arrow Bitch had been bestowed on Ivy at Annapolis when she had declined to take part in a drinking game during a tailgate party.

  The ULS/SAB dynamic was a thing that Dinah and Ivy exploited in meetings, even having meetings-before-meetings to plan how to use it.

  Good Looks Wasted had found its way to Dinah in the aftermath of her new haircut, as the result of an improbable chain of “Reply to All” mishaps. She had brought it to Ivy, breathless with excitement, and they had enshrined “GLW” in their private codebook.

  “I forgot,” when spoken in a breathy, little-girl voice, was a shorthand way of saying “I forgot to put on my makeup,” quoted verbatim from a NASA PR flack.

  SAR was from a tart exchange between Ivy and a NASA administrator who, upon reading one of her reports, had criticized her for having an “almost pathological predilection for unnecessary abbreviations.” This had struck Ivy as a bit odd, given that every other word in NASA prose was an acronym. When Ivy had asked for clarification, she had been told that her abbreviations were “schoolgirlish and recondite.”

  Space Camp (which both Ivy and Dinah had attended as teens, though at different times) was what they called not just Izzy, but the whole subculture of NASA manned spaceflight.

  “What are you going to say to the Maternal Organism?” Dinah asked, as Ivy rummaged in the back of a storage bin for her bottle of tequila.

  Ivy stiffened for a moment, then pulled out the bottle and swung it toward Dinah’s head like a club. Dinah didn’t flinch, just watched it glide to a halt above her head. “What?”

  “I can’t believe that the Morg has so taken over my wedding that the first thing that comes into your mind is how she’s going to react.”

  Dinah looked mildly sick.

  “Don’t worry about it,” Ivy said, “you forgot.” To put on your makeup.

  “Sorry, baby. I was just thinking . . . you and Cal are still going to get married, and have a great life, no matter what.”

  “But the Morg is going to take the hit,” Ivy said, nodding, as she poured tequila into a pair of small plastic cups. “Having to reschedule everything.”

  “Sounds like she’s kind of in her element doing that, though,” Dinah said. “Not to minimize it or anything.”

  “Totally.”

  “To the Morg.”

  “The Morg.” Dinah and Ivy tapped their plastic cups together and sipped at the tequila. One of the fringe benefits that came of being in the torus was that you could drink normally instead of sucking everything through tubes. The lower gravity took some getting used to, but they were old hands at it by now.

  “What’s up with your family? Did you hear from Rufus?” Ivy asked.

  “My father desires raw data files from Konrad’s Wide-Field Infrared Observation Platform, which he has read about on the Internet, so that he can satisfy his personal curiosity about the thing that hit the moon.”

  “You going to Morse code those down to him?”

  “His Internet is working. He has already created an empty Dropbox folder. As soon as I provide him with the files, he’ll go back to his usual grousing about how his taxes are too high and the federal government needs to be scaled back to a size where he can personally stomp it to death with steel-toed boots.”

  WHAT ASTRONOMERS DIDN’T KNOW OUTWEIGHED, BY AN ALMOST infinite ratio, what they did. And for persons used to a more orderly system of knowledge, with everything on Wikipedia, this created a certain perception of incompetence, or at least failure to perform, on the part of the astronomical profession whenever weird things happened in the sky.

  Which was every day, actually. But most of them could be seen only by astronomers and so they were able to keep them a sort of trade secret. Blatantly obvious events such as meteorite strikes caused Doc Dubois’s phone to sing. The singing usually portended a series of appearances on talk shows where, among other things, he would be asked to explain why astronomers hadn’t predicted this. Why hadn’t they seen the meteor coming? Wasn’t it just the case that they were a bunch of good-for-nothing propellerheads?

  A little bit of humility seemed to go a long way, and if the pundits didn’t cut him off too soon he was frequently able to work in a plea for more government support of science. For members of the general public might not care about Wolf-Rayet stars in the Quintuplet Cluster, but they definitely saw why having hot rocks fall on one’s head was a good thing to avoid.
