But even with all that, just because of quantum fluctuations, it would take more energy than the SSC could muster to keep a hole that size open for longer than a few microseconds. So the labs biggest insight was that you didnt have to do that. You could just create a new wormhole in the same place, so to speak. Or, more specifically, along the same predictable curve on the Cauchy hypersurface. And then youd make another and another. The gamma beams that would encode my consciousness would be phased to enter each of the series of holes, and when they came out the other end, theyd be lined up at the right point behind us on the space-time curve, that is, in the past.
Actually, the trickier part was the next stage, that is, working out the angles. A2, who despite working for Taro had a degree in experimental physics from Pohang University of Science and Technology, said that it had taken more man-hours to get working than all the other elements of the Kerr space system put together.
If you just sit still, at the end of a minute youll have moved about 85,000 miles from the point in the universe you started from. So if the beam encoding my SOS emerged in the past at the same place it started, it would come out in the middle of nowhere, somewhere roughly midway between the sun and Alpha Draconis. So a little tweaking was a must. Of course, our GPS sent our exact position to the Swiss team, so where we were now wasnt a problem. But they also had to extrapolate our location into the past, to identify the point in space-time where most or at least many of the atoms in this room would have been exactly 170,551,508 minutes ago.
This requires fine-tuning to about 1 part in 1032. And of course the data on where earth was doesnt go back that far. Even using old eclipse records and whatever other astronomical archives they could find, the cone of accuracy for AD 664 was way, way too large. And of course the sun also moves. Just like the earth, it shrinks and inflates. It jiggles around its plasmic core. It gets buffeted by meteors and cosmic winds. So for beyond-astronomical precision theyd had to zero in the transmission largely by trial and error. Theyd started by blasting energy into the center of a big block of freshly cut wood sitting on a lab table in a basement room. Theyd angle the beam so that it would emerge five minutes agowhich is already in outer space, in fact a few thousand miles behind where it is nowand the gamma beams would shake up the carbon isotopes in the center of the block so that theyd decay just a little more quickly than the ones on the surface. When theyd gotten that right they started aiming for further back in the past and directing the beam at sections of well-dated historical buildings in old mining towns and abandoned pueblos around Bryce Canyon, blasting the conjectured position with enough radiation to turn the uranium 238 in the foundations halfway to lead, drilling out samples, testing them, usually coming up empty, and trying it again a few feet away on the buildings foundation and a few million miles forward or back, in the path of earth through space. The calculations were fraught with tricksome variables. Even earths internal motion, which youd think wouldnt be a lot, had turned out to be a bitch. As you probably know, its gooey down there, and that causes wobbles in the rotation that can be very close to random. And even if you had that licked you had to take into account things like continental drift, erosion, changes in absolute land level versus the core of earth, orbital slips caused by passing comets, and a hundred other things. And there were similar problems with the spin of the sun and the Milky Way galaxy. Still, over the last two years theyd drawn a tight picture of where our planet was in the past, extending an imaginary helical track from the surface of earth out into space, out of the solar system, out of the Milky Way galaxy, and far back toward the center of our expanding universe.
Luckily, the other end of our wormhole didnt have to travel that far. They didnt need to load it on a spaceship and truck it out to Vega or wherever. It could stay here, right on earth with us, and from here it could be angled so that the energy they put into it emerged in different positions in space, the same way it could come out at different positions in time. In fact, the whole project had originally gotten started, way back in 1988, as part of a NASA space-travel program. Since the nineties Warren had been continuing the research, working more on the time angle. As of today, the programwhich was still housed at one of the big Ames Research Center servers in Mountain View, Californiacould tell you how to hit any given spot on earths surface at an exact second centuries ago. It was like shooting an arrow into the air and hitting the eye of a Tralfamadorian wasp on the far side of Titan. But assuming it all worked, the stream of data would emerge at the right point in space at the right time in the past, in this case, in Sor Soledads cell, three days before her death. Taros assistant A2 had done a whiteboard sketch of the concept for the last presentation to Boyle that made it all look pretty straightforward:
Like the Kerr space system, the Consciousness Transfer Protocol hadnt originally been developed for time projection. And it had also started from humble roots and grown slowly, over decades. In the 1980s it was still just planaria swimming through simple mazes at the University of Illinois in Champaign. One flatworm would learn the routine, and theyd record pulses from its little neural node and fire a repeating pattern of x-rays based on the recording into a second one, and the second would learn how to navigate the thing a little more quickly. The goal was to develop a surgical technique that could rewire parts of donor brains to make them easier to transplant. But by the early nineties the university was doing it with macaques, and in 2002 the Warren Research Group did their first human trials on terminally ill volunteers in India and Brazil. Two years ago theyd done what they said was their last real-time human trialthe first wet test that Marena had mentioned back at the Stakeand downloaded Tony Sics SOS into the head of a sixty-one-year-old Honduran man who was dying of stomach cancer. There was no measurable loss of Sics essential memories, cognitive ability, or personality. Or so they said.
I got the feeling, though, that theyd also done some other tests they werent telling me about. Probably theyd done at least one test like this one and sent Sics data into the mind of someone in the past. But I couldnt find out anything about it. Some things are just so illegal nobody wants to know about them, Marena said, as though all the other shenanigans Id found out about lately were just traffic violations.
And really, what we were doing wasnt nice. Before they started with my SOS, the Swiss team had sent a salvo of photons in a pattern designed to irreversibly confuse Soledads mind, or, as A2 put it, to wipe down the targets gray matter. Obviously, her brains so-called lower functions, like sensory and motor skills, had to be left intact. So what they called the wash wave wouldnt disturb what they call noetic memories, that is, semantic and spatial knowledge, things like how to speak the language or walk down stairs. But her episodic memoriesthat is, more contingent multiple copies. You could say that what we were doing was more along the lines of a photographic print, or rather a hologram. A holographic negative contains a 2-D record of the rates that light waves bounce off an object, and when you pass light back through the negative, it sculpts the waves back into position, as though the object were still there. And every bit of the hologram has a complete picture. That is, if you cut the negative in half and put light through it, you still see the whole image, still in 3-D, although with some loss of detail.
But you do need a human eye to read it. Like a hologram, the record of my consciousness was just a template. It was only useful as a way of rewriting another system, and like I think I said already, at this stage of technology the only system large and complex enough to work was another human brain.
The upside of this was that none of the contentthat is, my SOShad to be interpreted. Beyond making sure it was as complete as possible, none of the people or programs working on the transfer had to know anything about what pattern encoded which memory, or caused what thought or action, any more than a camera would have to know whether the face it was taking a picture of was smiling. As long as the i
ntervals between each wave crest were precisely timed to mimic hippocampal outputmost long-term memories go through the hippocampusthe cortices would think they were getting information in-house.
Of course, gamma photons have a lot of charge, and they can do a lot of damage. Thats why the Gamma Knife is the hot tool in microsurgery. In this case, the hostas they liked to call her, as though she were inviting us inwould be exposed to nearly two sieverts of radiation, not an immediately terminal dose, but enough to get some tumors or personal things, like, say, what her father had looked like or what shed worn to her first communiondearticulated, and she would become an anterograde amnesiac.
So what we were doing wasnt much different from murder. No, lets be honest. It was murder.
According to Taro, who wasnt a neurobiologist but who in his polymathic way knew a lot about the research, the first tests had come out spotty. Subjects picked up some, but not enough, or the induced memories got misinterpreted, or they got confused with unerased innate ones. Maybe the poor Honduran guy had wondered whether he was himself, or Tony Sic, or just crazy. In the last year, though, theyd found a solution to this: massive redundancy. Brains dont store a single memory or skill set or whatever in a single spot. Its distributed through different neural networks and sometimes even across different cortices. So we could send each gamma packet many, many times. If one of my memories didnt take hold in a given part of Soledads brain, it still had a good shot at getting picked up by some other area on the next go-round. This strategy also took advantage of the fact that memory has a tendency not to overwrite. That is, when the neurons were in their confused, amnesiac state, right after the wash wave, they were especially eager to form new connections. But once a microregion of the brain had encoded a bit of memory, it was more or less set there, and the next induced memory would have to settle somewhere else.
Presumably, if the target brain was still healthy, everything that I needed to be me would be represented somewhere. Even though the old saw about how you use only 10 percent of your brain isnt at all true, theres still enough room in there for a lot of storage. Not that that would matter this time. Anyway, since the waves were spread out over hours, her brain wouldnt fry. Instead, it would experience something like a series of simple focal seizureswhich are too localized to interrupt consciousnessand then would immediately begin to repair itself. It would form new attachments and run new routines. It would stabilize its EEG. And as it went on livingespecially in the first few hours, but also for days afterwardit would start discarding duplicated memories in order to make room for new ones. It would react and learn and function normally. The same way your sleeping brain makes sense of random firings from sensory and motor nerves by converting the noise into a more or less coherent dream, the abadesas brain would heal by building new memories that would correlate with mine, and would even construct a way of understanding the world that would be very much like mine, so much so that it would think of itself as me. But her rewired brain would never replicate mine exactly. It would be more as though she were watching a tremendously detailed movie of my life, and then, as she left the theater, she would find that she didnt remember her own life and would begin to think that instead, shed lived mine.
In fact, if everything went well, she wouldnt even be aware of a difference. Shed be lying on her pallet staring at her crucifix, and shed start to forget things. Her face would begin to feel hot from the increased blood flow through her vertebral and carotid arteries as millions of neurons fired over and over to the point of exhaustion. Technically, thered be a short period of neural bursts and then a longer refractory period of suppression. Her breathing and digestion and everything would, presumably, cruise on as normal, but shed slowly forget who she was, and where she was, and then even how to speak. But then, like muscles rebuilding themselves after heavy lifting, her neurons would put the new connections together, and in a very little while shed have constructed a sense of identity that, if I were able to meet her, I would recognize as my own.
But of course I wouldnt meet her. Back in 1686, the abadesa would live two more days, do a few thingssecret things that werent yet represented in our historical recordand then she would die on schedule. Shed be laid out in the habit she died in, without being embalmed or even washedin those days, the brides of Christ trusted that their sempiternal purity would keep them from putrefyingand cured for one year in a well-ventilated room in the almacén. Then she would have been moved to where she was now, and if shed still been able to see with her deflated and shriveled eyes, the window in the casket would have let her see silhouettes in the chapel archway, her aging sisters hobbling in, praying, and rustling out, and then new sisters and priests, and then strangers, and then strangers in odd and immodest clothing, peering at her through boxes and not praying at all. One evening an oddly colored flood of unvarying light would spill in from the nave, and it would come back every evening after that. The offering candles that had lit her through most nights would dwindle but never quite stop. And then, on one of the nearly identical and almost innumerable afternoons, she would have seen Marena, Dr. Lisuarte, Grgur, Hitch, and me as we walked in, a little hesitantly, to desecrate her corpse.
Can you go wake up that queen? Marena asked Grgur, who was trailing behind with Hitch. Thanks. She meant the priest.
They set up a halogen work light and turned it on the retablo and it squelched any touch of Gothic mood the scene otherwise would have had. Padre Panuda came in with a little sort of camp stool and sat in front of the casket. He got out his keysthere were about a hundred of them, on a loop of green twenty-pound fishing linefound the right one, teased open the old Yale padlock, and tried to pull up the dark oak lid. It stuck. He stood up and tugged. The coffin lifted up but the lid stayed on. Hitch found a kind of miniature pry bar in his kit and we tried that, but it was no good. Finally Grgur found a couple of old squarehead nails on the head and foot ends of the frame and yanked them out with a multitool. Padre Menudo jiggled the thing and pulled at the thing again and it croaked open. There was a cloud of vegetal smells, like basil and old roses. He peered in through the cloud and moved aside a couple of big corsages or nosegays or whatever. The petals shattered and the shards fluttered around.
Mejor hacemos nosotros esta cosa, Marena said in surprisingly decent Spanish. Wed better do this part ourselves. The priest said okay, blessed the place again, and left. The three of us stood there for a minute, looking at the corpse.
Me da rabia, Hitch said. That is to say, This is giving me rabies. Meaning, Its bumming me out. I could hear his arm move like he was crossing himself.
We were all going to hell anyway, I said.
Hey, lets get Jed, Marena said, imitating the old Life cereal commercial. Hell touch anything.
Its okay, I trust you, I said.
No, really, go ahead.
Im sure you dont have anything up your sleeve.
I know, justfor crying out loud, just go for it. Really. Im serious.
Okay, fine, I said. I squatted down. Lisuarte had thought I was still a little speedy, so shed given me a hypospray of noraephron, and now I was wobbling a little. I reached into the casket and started to peel back the layers of homespun wool and then muslinish cotton skirts from around the bodys crotch level, but they were all sort of oily and crumbly and just broke where I folded them back. She was an air mummy, so underneath the fabric her skin was in pretty good condition, almost a dark green, dripping over this little delicate abstract Henry Moorish pelvis. I felt for the anterior iliac spine and then down at a forty-five-degree angle, pressed to find the pubic symphysis, and hooked two fingers up under it. There was all this hard, sharp skin in there and under it there was this sort of stringy greasy stuff. Grave wax. I found what felt like the right two flaps of skin, like dried jade-plant leaves, and moved my fingers up into the vagina, through clogs of c
rumbly adipocere. Poor lady. Of course, Id done this with one or two shall-we-say mature women in my day, but this was a new record. Just relax, babe. My finger hit what I thought at first was the coccyx, but then I realized it was what I was looking for and got two fingertips around it. A flood of mixed relief and anxiety sort of inflated my blood vessels, to what felt like Michelin Man proportions. I pulled my hand out and rolled the thing around on my palm. It was a little hexagonal box, about the size of a large calcium-magnesium tablet, black now but I supposed made of copper. It was crusted with crumbs of grave wax and I scuffed them off with my thumbnail. It wasnt a locket. I guess it must have been a needle case or something. Lisuarte had laid out a little lightbox and magnifier on a towel on the floor, and I set the thing down and looked at it. Some of the goo on one end looked like it might be red sealing wax. After a minute of messing around with tweezers and a dental scraper I got the little lid off. There was a black roll inside. I tweezed it out and when I put it down on the plastic it seemed to be made of metal. I started unrolling it carefully, but then it turned out it was really a thin, triangular sheet of hammered silver foil, about the size and shape of a Cape of Good Hope stamp. Maybe shed torn it off a pyx or something. Maybe I had, rather. At first it looked blank, but when I breathed on it you could see lines scratched on with a needle, in a twitchy mix of uncial script and my own five-thumbed south-paw handwriting:
