Tandem: The Many-Worlds Trilogy

by Anna Jarzab

  “Dr. Moss is your friend with all the theories about analogs, isn’t he?”

  Thomas nodded. “About Dr. Moss,” he said cagily, tugging at the cuffs of his suit jacket. “He’s not technically a medical doctor.”

  “What are you talking about? He gave me a shot!”

  “I couldn’t call a real doctor,” Thomas explained. “Dr. Rowland, the royal physician, wouldn’t have been satisfied with giving you a little antihistamine and going about his night. He would’ve been suspicious; he would’ve wanted to do blood work and all kinds of tests on you, and I think you know what that might’ve yielded.”

  “Would it have proven I wasn’t Juliana?”

  “I don’t know.” Thomas shrugged. “But it’s possible. I knew the General wouldn’t want to risk it, so I took the liberty of calling Dr. Moss instead.”

  “What kind of doctor is Dr. Moss?”

  “Theoretical physicist,” Thomas said with a wry smile, perhaps thinking of my “family business.” My stomach dipped with the impact of a sudden sadness at the thought of Granddad and my parents, but I did my best to put it out of my mind. I couldn’t allow myself to fall apart with missing them, not when I was so close to getting answers about my mysterious ability and its implications for my quest to return home. “He’s completely brilliant, Mossie. He invented the anchors. He knows everything there is to know about parallel universes and analogs.”

  I fiddled with the anchor. Most of the time I forgot it was there. “Mossie?”

  A shy grin transformed his face. “I like Dr. Moss. And you’ll like him, too.”

  “How can you be so sure?”

  “Because,” he said with confidence as the elevator arrived at Subbasement F. “The General hates him.”

  The F level contained only a short hallway with one steel door opposite the elevator. A sign on the door read:

  SUBBASEMENT F

  HIGHLY CLASSIFIED

  NO ONE BELOW LEVEL 6 CLEARANCE ADMITTED WITHOUT A DOD ESCORT.

  The LCD screen next to the door wasn’t green, or even blue, but bright red and pulsing, a very clear sign that no one was welcome down here, me included. But Thomas had Level 6 clearance; his handprint changed the screen to blue, and the code he punched in unlocked the door. It swished open, revealing a large, slick laboratory just beyond the threshold. Loud music blasted out of unseen speakers, and strangely enough, the song was one that I recognized.

  “Mossie!” Thomas shouted. I glanced around the windowless laboratory, taking in several imposing machines, digital boards covered with hastily scribbled mathematical formulas, and tables cluttered with all manner of things: burbling Bunsen burners, stacks of files, and piles and piles of books. There was one thing missing, however—Dr. Moss.

  “Mossie!” Thomas cried again. The elderly man popped up from behind one of the shuddering machines. When Dr. Moss saw Thomas, he grinned and shuffled over to an old-fashioned record player. An earsplitting scratch filled the air as he removed the needle from the spinning LP.

  “Thomas!” He rushed forward to shake Thomas’s hand. When his eyes landed on me, his grin grew so wide I thought it might crack his face in half. “And look who you’ve brought! Our little Earthling.”

  I wrinkled my nose at the term, despite the fact that it was as accurate a description of what I was as anything else. I preferred it to “analog,” but all I could think of were the alien movies I’d seen as a kid.

  “Remind me of your name, dear,” Dr. Moss said. “I’m afraid I’ve forgotten it.” He tapped himself on the temple. “Mind like Swiss cheese, and growing holier by the day!”

  “Sasha,” I told him, gathering my confidence. It seemed like forever since I’d said my own name out loud. “Sasha Lawson.”

  “That’s right. Ms. Lawson.” Dr. Moss grinned at me. “I can’t tell you how happy it makes me to find you got through the tandem in one piece.” I didn’t doubt it; he’d invented the anchor that had brought me to Aurora, so if I hadn’t survived the journey, it would’ve been at least partially his fault. I shot Thomas a dubious look. This was the man who was supposed to help me? He seemed a little nuts.

  “Was that Chuck Berry you were playing?” I asked.

  Dr. Moss snapped his fingers, impressed. “Right you are. I was introduced to the Father of Rock and Roll by another one of your kind many years ago, and I’ve never lost the taste.”

  Dr. Moss sat down on a nearby stool and drummed his fingertips on his knee. The steel tabletop was littered with notebooks containing lines of cramped, handwritten notes. Seeing them—the whole place, in fact—reminded me of Granddad’s lab at the university, except larger and shinier. On the table there stood a large glass bottle of the type that might once have contained vodka, and it was filled with tiny origami stars in a rainbow of colors. In fact, they were scattered all about, piling up in the empty spaces and peeking out from beneath his notes.

  I picked up a green one and held it between my thumb and forefinger. I wondered if the one I’d found in Juliana’s nightstand had its origin here, in Dr. Moss’s lab. “Did you make these?”

  “Actually,” Thomas said, taking it and dropping it into the bottle, “they’re mine.”

  “Yours?” Then had Thomas given Juliana the blue star, as some sort of token or memento? Was that why she’d kept it? Was that why she’d hidden it away?

  He nodded. “When I was little, I was anxious and fidgety. One of my teachers taught me how to make these, and told me that whenever I felt antsy, I should just take out a piece of paper, rip it up, and make stars.” He gave me a wry smile. “The habit stuck.”

  I smiled at the mental image of a boyish Thomas sitting at a classroom desk, making stars with his restless hands. “Aw, that’s sweet.”

  He rolled his eyes; apparently, “sweet” was not a compliment to a soldier. He ran his fingers through his hair and dipped his head to hide a faint pinkness that colored the tips of his ears. “Anyway,” he said. “I spent a lot of time down here with Mossie during the planning stages of Operation Starling, which is, you know, why they’re here.”

  “I’ve been keeping them safe for you, boy,” Dr. Moss said, not even bothering to look up from a nearby text that had drawn his attention away from us.

  “What’s Operation Starling?” I asked. Dr. Moss swiveled around and Thomas lifted his eyes to mine. A moment of silence passed. “Oh,” I said, my voice flat with realization. “Right. Why do you call it that?”

  “It’s, um … kind of a joke,” Thomas said, with a soft snort of self-effacing laughter.

  “Oh really? What’s so funny about it?”

  “Not funny,” he said. “It’s just that Juliana’s KES code name is ‘Sparrow.’ Sparrows and starlings are related, I guess.”

  “They’re from the same biological order,” Dr. Moss explained. “Passeriformes.”

  “Fascinating.”

  “It was his idea,” Thomas said, pointing at Dr. Moss. “As you can probably imagine.”

  “Well, children, I haven’t got all day,” Dr. Moss said. “And I assume it wasn’t an interest in ornithology that brought you here, so why don’t you tell me what did, eh?”

  Thomas drew in a deep breath. “We have a situation.”

  “Oh? What sort of situation?”

  “Go ahead,” Thomas said, putting a hand on the small of my back and pushing me forward. “Tell Mossie what you told me.”

  I still wasn’t quite sure about Dr. Moss, but I didn’t see that I had a better option, so I explained everything as best I could. This time, it came out easier, and more intelligibly. As he listened to me describe my “situation,” excitement bloomed across Dr. Moss’s face.

  “Well,” he said when I was finished, with soft but potent enthusiasm. “That is interesting.”

  Just interesting? “Have you heard of that happening to other people?”

  “Other people?” He tapped his chin with his fingers. “Not as such.” The wheels of Dr. Moss’s mind were turning swiftly
and energetically, fueled by a new mystery, and his eyes held that same glint of excitement Granddad used to get when he was on the verge of a particularly gratifying discovery in his own work. “What do you know about parallel universes, Ms. … ?”

  “Lawson,” Thomas and I provided in unison.

  “Right.” His hands flapped in the air, an impatient gesture meant to spur me to answer.

  “Not a lot,” I admitted. “My grandfather is a physicist, but it’s not something I was personally very interested in—up till now, anyway.”

  “Hmmm.” My lack of knowledge disappointed Dr. Moss, but he soldiered on with an air of great burden. “Then I guess I’ll have to start with the basics, won’t I?”

  “That would probably be best,” I said.

  Dr. Moss nodded, rushing to a keyboard and typing a series of quick commands. There was a large screen on the opposite end of the laboratory that took up almost the entire wall. When Dr. Moss was finished, the screen, previously blank, held one inscrutable image.

  I know that symbol, I thought with a sudden, grave certainty. I struggled to remember where I had last seen it, but I couldn’t. Was it something Granddad had once shown me? Then I realized—it was the Libertas insignia, except that instead of stars it was made up of dots.

  “What’s that?” I asked, advancing toward the screen.

  “No touching the equipment, if you please,” Dr. Moss scolded. I drew my hand away.

  “That is a tetractys,” Dr. Moss told me. “A mathematical symbol dating back to about 500 BC. But the shape doesn’t matter—it’s what the tetractys represents that’s important.”

  “And what’s that?” I asked, squinting so that I could read the type.

  “Universes.” I could hear a grin in his voice when he said the word. If nothing else, Dr. Moss certainly had a flare for the dramatic.

  “As we are all well aware, there is a large number—perhaps infinite number—of universes in existence,” Dr. Moss continued. “But what you may not know is that there are many different kinds of universes. What you see on the screen is a method I’ve developed for categorizing universes in their many forms.” Dr. Moss took one look at my baffled expression and said, “Allow me to explain further.”

  “Please do,” I urged.

  “For the purposes of this demonstration, let us consider Earth to be our home universe,” Dr. Moss said with a nod in my direction. “At the top of the pyramid, you have Earth, and all of the universes that are separated from it by what I’ve taken to calling zero degrees. These are universes that are virtually indistinguishable from Earth itself. They are nearly identical, apart from minuscule changes that have no global consequences. For instance, Thomas is wearing a blue tie today. In a zero-degree universe, he’s wearing a black tie. A small difference with no measurable impact.

  “The second row is representative of all universes that are separated from Earth by one degree. These are distinguishable from Earth, but are not so different that the world appears substantially changed. For instance, if you were comparing Earth to another world with one degree of separation, at any given time the President of the United States could be a different person in each world, but there would still be a President of the United States. Do you understand?”

  “I guess.”

  “The third row is where it gets interesting,” Dr. Moss said. “It represents universes that are substantially differentiated from one another. At some point in time, history took a very different turn, resulting in an altered worldscape. Earth and Aurora are universes separated by two degrees.”

  “Because of the Last Common Event,” I said, remembering what Thomas had told me—in Aurora, George Washington had died during the Revolutionary War, and the war was lost. As a result, history had forged a new route.

  “Precisely!” Dr. Moss was growing more and more excited by the second.

  “So what’s the fourth row?” I asked. Granddad would’ve thought Dr. Moss was a lunatic, but he would’ve loved his theories, and his penchant for organization.

  “Universes separated by three degrees are highly differentiated from each other,” Dr. Moss said. “In these universes, something happened that was so major that it completely changed the world scape. Of course, at the moment these third-degree universes are entirely theoretical. We’re incapable of proving that they actually exist. And there might be other universes still, separated by four, five, six degrees, with entirely different laws of physics, perhaps! You can see how difficult it is to imagine what such universes might look like.”

  “What does any of this have to do with analogs?”

  “Everything!” Dr. Moss cried. “People are products of their environments. The more different two universes are, the more different the analogs in those universes will be from each other, not in appearance but in circumstance. In a universe where the differences are subtle—universes of zero, or even one degree—your analog is much more likely to be like you. In these universes, analogs share names and genealogical backgrounds and identities, and if you were to compare the lives of analogs in these universes, you would find that they are being lived almost entirely in parallel with your own, allowing for relatively few slight variations. Of course, there are exceptions. There are always exceptions.”

  “Can I ask you something?” Dr. Moss gave me a curious look. “How come Juliana and I have different parents?”

  “I’m not sure I understand your meaning,” Dr. Moss said. “You’re different people.”

  “I know that, but, if we’re analogs, shouldn’t our parents be analogs, too? And our grandparents? Isn’t that how biology works?” This was something I had been wondering for a while, but no one seemed capable of explaining it to me. If anyone knew the answer, though, Dr. Moss would.

  “Not necessarily,” Dr. Moss said. “Because of the LCEs, those linchpin moments that create divergent histories, analogs in second-degree universes and higher do not, for the most part, share the same genealogical backgrounds or identities. Although, again, there are outliers; analogs in second-degree universes can, in unique cases, live their lives along very similar paths, but it’s rare. And your analog in a third-degree universe is likely to be even more different from yourself than Juliana is.”

  “I don’t see how that’s possible,” I said. I was a normal high school junior; Juliana was a princess. How much more different could two lives be?

  “Believe me, Ms. Lawson—anything is possible.”

  “I still don’t understand,” I said. “What about DNA? If we look the same, shouldn’t we come from the same parents?”

  “Are you familiar with Anaximander’s theory of apeiron?” Dr. Moss asked. I stared at him blankly. He sighed. “No, I thought not. Anaximander was a Greek philosopher in the sixth century BC. Apeiron means ‘boundless’ or, perhaps more colloquially, ‘infinity.’ It describes a sort of hyperreality from which everything ultimately descends. Anaximander believed that everything we see in every world originates in apeiron, that what exists in the universes is a mere fragment of a greater whole. As far as I can tell, that’s what an analog is—a worldly fragment of one whole and perfect being that exists only in apeiron.

  “Have you ever visited a hall of mirrors, Ms. Lawson?” I nodded. “Imagine standing in one, then. Everywhere you turn, there are multiple reflections of your own image. The mirrors are expertly arranged so that these reflections appear to multiply in every direction, stretching out into infinity. You look alike, you move in perfect harmony, but the reflections are not you. They simply have their origin in you. You are the primary being, and they are mere copies. That is an imperfect but adequate example of what I mean.”

  “And in this scenario, I’m the apeiron being and they’re … analogs?” I ventured.

  “In a manner of speaking. Technically, in a hall of mirrors, you—your physical self that stands before the mirrors—is a sort of source code that exists only in apeiron. Your DNA—and everything else that makes you look as you do—adjusts in orde
r to deliver that predetermined result.”

  He turned back to his keyboard and brought up a three-dimensional illustrated rendering of ten or so human beings standing in a dispersed group, connected to each other by dotted lines. Dr. Moss indicated one of the lines.

  “Dr. March and I—”

  “Who’s Dr. March?”

  “Don’t ask,” Thomas muttered under his breath.

  “Dr. March was my research partner,” Dr. Moss said. I shot Thomas a questioning look. What was so weird about that?

  “Dr. March and I developed a theory—that analogs with a single apeiron source are connected across the universes by what we call a ‘tether,’ ” Dr. Moss said. “An invisible cord that binds you all together, through the tandem and beyond.”

  “A cord? A cord made of what?”

  “Energy,” Dr. Moss said. “Dark energy, to be precise. Don’t worry, it’s not nearly as ominous as it sounds. The word ‘dark’ merely implies that it’s hypothetical. We believe it exists because when two analogs come into contact with one another, energy is released, which causes the destruction you witness as a disruption event.”

  “So this tether … ,” I prompted, trying to get him back on point.

  “It’s the thing that makes you and Juliana—and countless, perhaps infinite copies of you out there in the multiverse—analogs and not identical twins, or clones, or mere coincidental look-alikes. Every analog is connected to each of their other analogs by one of these tethers, forming an intricate web across multiple parallel cosmos. Like DNA, the tether is what carries the code that informs your physical similarity to your other analogs.” Dr. Moss smiled, impressed with himself. “To put it simply: you aren’t connected to your analogs because you look alike—you look alike because you are connected. Your appearance is a kind of echo, and the tether is the medium upon which it travels. The bond is stronger than genetics; it’s probably one of the strongest forces we’ve ever encountered. Theoretically, of course.”

  “An echo?” The word sounded so empty and lifeless. “Does that mean that I’m not really a person? That I’m not really me?”
