“I, I think—hell. I assumed that if it was possible to do something, it would already have been done, surely?”
“That’s the assumption everyone who has given the subject a moment’s thought comes up with. It tends to deter experimentation, doesn’t it, if you believe an alley of inquiry has already been tried and found wanting? Even if the assumption is wrong.”
“I—I feel dumb.”
(Pause.) “You’re not the only one of us who’s kicking himself. There have been a number of unexplained disappearances over the centuries, and simple murder surely doesn’t explain all of them—but the point is, nobody who succeeded came back to tell the tale. Which brings me to the matter at hand. When Helge reappeared with the family Lee in unwilling thrall, I had reason to send for the archivists. And to have my staff conduct certain preliminary tests. It appears that the Lee family design has never been tested in the United States of America. And our clan symbol doesn’t work in New Britain. That is, it doesn’t in the areas that correspond to the Gruinmarkt. The east coast. But that’s all we know, Huw, and it worries me. In the United States, the authorities have made their most effective attack on our postal service for a hundred years. This would be a crisis in its own right, but on top of that we have the pretender to the throne raising the old aristocracy against us in Niejwein. He can be contained eventually—we have means of communication and transport that will permit us to meet his army with crushing force whenever he moves—but that, too, would be crisis enough on its own. And I cannot afford to deal with any new surprises. So I want you—I have discussed this with members of the
council—to set your very expensively acquired skills to work and do what our none-too-inquisitive ancestors failed to do.”
“You want me to, to find out how the sigil works? Or…what?”
(Clink of glassware.) “When there was just one knot, life was simple. But we’ve got two, now, and three worlds. I want to know if there are more worlds out there. And more knots. I want to know why sometimes trying a design gives the world-walker a headache, and why sometimes the experimenter vanishes. I want to know, Sir Huw, so that I can map out the terrain of the battlefield we find ourselves on.”
“Is it really that bad?”
(Pause.) “I don’t know, boy. None of us know. That’s the whole point. Can you do it? More importantly, what would you do?”
“Hmm.” (Pause.) “Well, I’d start by documenting what we already know. Maps and times. Then there are a couple of avenues I would pursue. On the one hand, we have two knots. I can see if the clan knot is failing to work in New Britain because of a terrain anomaly. If, say, it leads to a world where the world-walker would emerge in the middle of a tree, or underwater, that would explain why nobody’s been able to use it. And I’d do the same for the Lee family knotwork in the United States, of course. That’s going to take a couple of world-walkers, some maps and surveying tools, and someone to report back if everything goes wrong. Next, well…once we’ve exhausted the possibilities, we’ve got two knots. I need to talk to a mathematician, see if we can work out the parameters of the knots and come up with a way of generating a family of relatives. Then we need to invent a protocol for testing new designs: not so much what to do if they don’t work, but how to survive if they take us somewhere new. If this works, if there are more than two viable knots, we’re going to lose world-walkers sooner or later. Aren’t we?”
“I expect so.”
“That’s awfully cold-blooded, isn’t it, sir?”
“Yes, boy, it is. In case it has slipped your attention, it is my job to be cold-blooded about such things. I would not authorize—I suspect my predecessors did not authorize—such research, if the situation was not so dangerous. The risk of losing world-walkers is too high and our numbers too few for gambling. Already there have been losses, couriers taken in transit by American government agents. You met the Countess Helge. Your opinion…?”
“Helge? She’s, she’s—what happened to her? Shouldn’t she be here, given her experience?”
“I am asking the questions, Sir Huw. What was your opinion of her?”
“Bright…inquisitive…fun, I think, in a scary way. Where is she?”
“‘Fun, in a scary way’…yes, that’s true enough. But she scared too many cousins, Huw, cousins who lack your sense of fun. I did what I could to protect her. If she surfaces again, well, circumstances have changed, and it may be possible to distract her pursuers, as long as she is not involved in the regrettable business unfolding in New York. But for the time being, she is not available, and so I am turning to you.”
“I’m, um, I’m at your disposal, sir. How would you like to proceed?”
“Write me a report. No more than three pages. Tell me what you’re going to do, what resources you need, what people you need, and what you expect to learn from it. I want your report no later than the day after tomorrow, and I want you to be ready to begin work the day after that.”
“Sir! That’s rather—”
“What, you’re going to tell me you’ve never written a grant proposal in a hurry? Please don’t insult my intelligence.”
“I wouldn’t dream of it, sir! But it’s going to cost, people and money—”
“Let me worry about that. You just tell me what you need, and I’ll make sure you get it.”
“Wow! Thank you—”
“Don’t thank me, boy. Not until it’s over, and we’re still alive.”
END TRANSCRIPT
Dr. Hu was alarmingly young and bouncy, a Vietnamese-American postdoc with a ponytail, cargo pants, sandals, and a flippant attitude that would have annoyed the hell out of Eric if Hu had been working for him. Luckily Hu was someone else’s problem, and despite everything, he’d been cleared by security to work on JAUNT BLUE. Which probably means the Republic is doomed, Eric thought mordantly. Ah well, we work with what we’re given.
“Hey man, the professor told me to give you the special tour. Where you wanna start? You been briefed or they dropping you in it cold?”
Eric stared at him. “I’ll take it cold.”
“Suits me! Let’s start with…hell. What do you know about parallel universes?”
Eric shrugged. “Not a lot. Seen some episodes of Sliders. Been catching up on some sci-fi books in my copious free time.” The writers they’d sounded out hadn’t been good for much more than random guesses, and without priming them with classified information that was all they could be expected to deliver. It had been a waste of time, in his opinion, but—“and then there’s the day job.”
“Heh. You bet, boss!” Hu laughed, a curious chittering noise. “Okay, we got parallel universes. There’s some theoretical basis for it in string theory, I can give you some references if you like, but I can only tell you one thing for sure right now: we’re not dealing with a Tegmark Level I multiverse—that’s an infinite ergodic universe, one where the initial inflationary period gave rise to disjoint Hubble volumes realizing all possible initial conditions.”
Eric crossed his arms and frowned. “So you’ve ruled that out.” Asshole? Or show-off?
“Yup!” Hu seemed unaccountably pleased with himself. “We can get there from here, which rules out Level I, because in a Level I multiverse the parallel universes exist in the same space time, just a mind-bogglingly huge distance apart. Which means we’re dealing with either a Level II, Level III, or Level IV multiverse. I’m in the cosmology pool—we’ve got an informal bet running—that it’ll turn out to be a Level IV theory. Level II depends on a Linde chaotic inflationary cosmology, in which you get multiple branching universes connected by wormholes, but travel between universes in that kind of scheme involves singularities, and the phenomenon we’re studying doesn’t come with black holes attached.”
Bumptious enthusiast, no social skills. Eric decided. He forced himself to nod, draw the guy out. “So you’re saying this isn’t a large scale cosmological phenomenon—then what is it?” Some of this stuff sounded half-familiar from his phys
ics minor, but the rest was just weird.
“We’re trying to work out what it is by a process of elimination.” Hu thrust his hands in his pockets, looking distant. “The thing is, we have no theoretical framework. We’ve got a lot of beautiful theories but they don’t account for what we’re seeing: we’re looking at an amazingly complex artifact and we don’t understand how it works. It’s like handing a nuclear reactor to a steam engineer in the nineteenth century. If you don’t understand the physics behind it you might as well say it works by magic pixie dust as slow neutron-induced fission. Absent a theoretical understanding all we can do is poke it and see if it twitches. And coming up with the theory is, uh, proving difficult.” He slowed down as he spoke, finishing on a thoughtful note.
Now’s as good a time as any… “What’s the black box you think you’re trying to reverse-engineer?” Eric asked, hoping to draw Hu back on track.
“Ah!” Hu jerked as if a dozing puppeteer had just realized he’d slackened off on the strings: “That would be the cytology samples Dr. James provided two months ago. That’s how we got started,” he added. “Want to see them? Come down to the lab and see what’s on the slab?”
Eric nodded, and followed Hu out through the door. If this is the Rocky Horror Picture Show, all we’re missing is the mad scientist. Hu made a beeline towards the maze of brown cubicle-farm partitions at the edge of the floor, and dived into a niche. When Eric caught up, he found him sitting at a desk with a gigantic tube monitor on it, messing with something that looked like the bastard offspring of a computer mouse and a joystick. “Here!” he called excitedly.
Eric glanced round. The neighboring cubicles were empty: “Where is everybody?”
“Team meeting,” Hu said dismissively. “Look. Let me show you the slides first, then we’ll go see the real thing.”
“Okay.” Eric stood behind him. “Take it from the top.”
Hu pulled up a picture and Eric blinked, taken aback for a moment. It was in shades of gray, somehow messy and biological looking. After a moment he nodded. “It’s a cellular structure, isn’t it?”
“Yeah! This slide was taken at 2,500 magnification on our scanning electron microscope. It’s a slice from the lateral geniculate nucleus of our first test sample. See the layering here? Top two layers, the magnocellular levels? They do fast positional sensing in the visual system. Now let’s zoom in a bit.”
The image vanished, to be replaced by a much larger, slightly grainier picture in which individual cells were visible, blobs with tangled fibers converging on them like the branches of a dead umbrella, stripped of fabric.
“Here’s an M-type gangliocyte. It’s kind of big, isn’t it? There are lots of dendrites going in, too. It takes signals from a whole bunch of rod and cone cells in the retina and processes them, subtracting noise. You with me so far?”
“Just about,” Eric said dryly. Image convolution had been another component of his second degree, the classified one he’d sweated for back when he’d been attached to NRO. “So far this is normal, is it?”
“Normal for any dead dried human brain on a microscope slide.” Hu giggled. It was beginning to grate on Eric’s nerves.
“Next.”
“Okay. This is where it gets interesting, when we look inside the gangliocyte.”
“What—” it took Eric longer, this time, to orient himself: the picture was very grainy, a mess of weird loops and whorls, and something else—“the heck is that? Some kind of contamination—”
“Nope.” Hu giggled again. This time he sounded slightly scared. “Ain’t nothing like this in the textbooks.”
“It’s your black box, isn’t it?”
“Hey, quick on the uptake! Yes, that’s it. We went through three samples and twelve microscopy preparations before we figured out it wasn’t an artifact. What do you think?”
Eric stared at the screen.
“What is it?”
A different voice said, “it’s a Nobel Prize—or a nuclear war. Maybe both.”
Eric glanced round in a hurry, to see Dr. James standing behind him. For a bureaucrat, he moved eerily quietly. “You think?”
“Cytology.” James sounded bored. “These structures are in every central nervous system tissue sample retrieved so far from targeted individuals. Also in their peripheral tissues, albeit in smaller quantities. At first the pathology screener thought he was looking at some kind of weird mitochondrial malfunction—the inner membrane isn’t reticulated properly—but then further screening isolated some extremely disturbing DNA sequences, and very large fullerene macromolecules doped with traces of heavy elements, iron and vanadium.”
“I’m not a biologist,” said Eric. “You’ll have to dumb it down.”
“Continue the presentation, Dr. Hu,” said James, turning away. Show-off, thought Eric.
Hu leaned back in his chair and swiveled round to face Eric. “Cells, every cell in your body, they aren’t just blobs full of enzymes and DNA, they’ve got structures inside them, like organs, that do different things.” He waved at the screen. “We can’t live without them. Some of them started out as free-living bacteria, went symbiotic a long time ago. A very long time ago.” Hu was staring at Dr. James’s back. “Mitochondria, like this little puppy here—” he pointed at a lozenge-shaped blob on the screen “—they’re the power stations that keep your cells running. This thing, the thing these JAUNT BLUE guys have, they’re repurposed mitochondria. Someone’s edited the mitochondrial DNA, added about two hundred enzymes we’ve never seen before. They look artificial, like it’s a tinker-toy construction kit for goop-phase nanotechnology—well, to cut a long story short, they make buckeyballs. Carbon-sixty molecules, shaped like a soccer ball. And then they use them as a substrate to hold quantum dots—small molecules able to handle quantized charge units. Then they stick them on the inner lipid wall of the, what do you call them, the mechanosomes.”
Eric shook his head. “You’re telling me they’re artificial. It’s nanotechnology. Right?”
“No.” Dr. James turned round again. “It’s more complicated than that. Dr. Hu, would you mind demonstrating preparation fourteen to the colonel?”
Hu stared at Eric. “Prep fourteen is down for some fixes. Can I show him a sample in cell twelve, instead?”
“Whatever. I’ll be in the office.” James walked away.
Hu stood up: “If you follow me?”
He darted off past the row of cubicles, and Eric found himself hurrying to keep up. The underground tunnel looked mostly empty, but the sense of emptiness was an illusion: there was a lot of stuff down here. Hu led him past a bunch of stainless steel pipework connecting something that looked like a chrome-plated microbrewery to a bunch of liquid gas cylinders surrounded by warning barriers, then up a short flight of steps into another of the ubiquitous trailer offices. This one had been kitted out as a laboratory, with worktops stretching along the wall opposite the windows. Extractor hoods and laminar-flow workbenches hunched over assemblages of tubes and pumps that resembled a bonsai chemical plant. Someone had crudely sliced the end off the trailer and built a tunnel to connect it to the next one along, which seemed to be mostly full of industrial-size dish-washing machines to Smith’s uneducated eye. A technician in a white bunny suit and mask was doing something in a cabinet at the far end of the room. The air conditioning was running at full blast, blowing a low-grade tropical storm out through the door: “Viola, the lab.”
Eric winced: the horrible itch to correct Hu’s behavior was unbearable. “It’s voilà,” he snapped waspishly. “I see no medium-sized stringed instruments here. And you’ll have to tell me what everything is. I know that’s a laminar-flow workbench, but the rest of this stuff isn’t my field.”
“Hey, stay cool, man! Um, where do you want me to start? This is where we work on the tissue cultures. Over there, that’s the incubation lab. You see the far end behind the glass wall? We’ve got a full filtered air flow and a Class two environment; we’re trying to get a
ccess to a Class four, but so far AMRIID isn’t playing ball, so there’s some stuff we don’t dare try yet. But anyway, what we’ve got next door is a bunch of cell tissue cultures harvested from JAUNT BLUE carriers. We keep them alive and work on them through here. We’re using a 2D field-effect transistor array from Infineon Technologies. They’re developing it primarily as an artificial retina, but we’re using it to send signals into the cell cultures. If we had some stem cells it’d be easier to work with, but, well, we have to work with what we’ve got.”
“Right.” The president’s opinion on embryonic stem-cell research was well known; it had never struck Eric as being a strategic liability before now. He leaned towards the contraption behind the glass shield of the laminar-flow cabinet. “So inside that box, you’ve got some live nerve cells, and you’ve, you’ve what? You’ve got them to talk to a chip? Is that it?”
“Yup.” Hu looked smug. “It’d be better if we had a live volunteer to work with—if we could insert microelectrodes into their optic nerve or geniculate nucleus—but as the action’s happening at the intracellular level this at least lets us get a handle on what we’re seeing.”
Live volunteers? Eric stifled a twitch. The “unlawful combatant” designation James had managed to stick on Matthias and the other captured Clan members was one thing: performing medical experiments involving brain surgery on them was something else. Somehow he didn’t see any of them volunteering of their own free will: was Hu really that stupid? Or just naive? Or had he not figured out how the JAUNT BLUE tissue cultures came to be in his hands in the first place? “What have you been able to do with the materials available to you?”
“It’s amazing! Look, let me show you preparation twelve in action, okay? I need to get a fresh slide from Janet. Wait here.”
Hu bustled off to the far end of the lab and waved at the person working behind the glass wall. While he was preoccupied, Eric took inventory. Okay, so James wants me to figure it out for myself. He wants a sanity check? So far, so obvious. But the next bit was a little more challenging. So there’s evidence of extremely advanced biological engineering, inside the Clan members’ heads. Quantum dots, fullerene stuff, nanotechnology, genetic engineering as well. Artificial organelles. He shivered. Are they still human? Or something else? And what can we do with this stuff?
