Factoring Humanity Part 6

Kyle had been brought up in Canada's United Church, an easygoing Protestant denomination. But he'd drifted away from it over the years and today was seen in a hall of wors.h.i.+p only when weddings or funerals required it. Oh, in moments of quiet reflection, he thought there might be some sort of Creator, but ever since that day when he was fifteen, he had been unable to believe in the benevolent G.o.d his church had preached.

Kyle's parents were out for the evening, and he had decided to stay up as long as he could. He didn't get to play with the remote when his father was home, but now he was flipping channels madly, hoping for something t.i.tillating on late-night TV. Still, when he came across a nature doc.u.mentary, he paused. You never knew when some topless African woman was going to wander into the scene.

He saw a female lion stalking a herd of zebras beside a water hole. The lion's tawny hide was almost invisible in the tall yellow gra.s.ses. There were hundreds of zebras, but she was interested only in the animals at the margin. The narrator spoke in hushed tones, like the commentator on his dad's golf shows, as if words added long after the footage was shot could somehow disturb the unfolding of the scene. "The lioness looks for a straggler," he said. "She wants to pick out a weak member of the herd."

Kyle sat up; this was much more vivid than the ancient, grainy Wild Kingdom Wild Kingdom episodes he'd seen before. episodes he'd seen before.

The lion continued to stalk. The background noises consisted of zebra hooves falling on baked earth, the rustling of gra.s.s, the calls of birds, and the droning of insects. The shadows were short, hugging the animals' legs like shy toddlers clutching their parents.

Suddenly the lion surged forward, legs pumping, mouth hanging wide open. She leaped onto a zebra's haunch, biting deeply into it. The other zebras began to gallop away, clouds of dust rising in their wake, the footfalls like thunder. Birds wheeled into flight, squawking loudly.

The attacked animal now had stripes of red running between its black and white ones. It fell to its knees, propelled down by the impact of the lion. The blood mixed with the parched soil, forming a maroon-colored mud. The lion was hungry, or at least thirsty, and it bit deeply into the zebra's flesh again, scooping out a wet mound of muscle and connective tissue. All the while, the zebra's head continued to move and its eyelids beat up and down.

The poor thing was alive, thought Kyle. It's bleeding all over the savannah, it's about to be eaten, and it's still alive.

A zebra. Genus Equus, Equus, they'd said in science cla.s.s. Just like a horse. they'd said in science cla.s.s. Just like a horse.

Kyle had done some riding at summer camp. He knew how intelligent horses were, how sensitive they were, how feeling feeling they were. A zebra couldn't be that different. The animal had to be in agony, had to be panicked, had to be terrified. they were. A zebra couldn't be that different. The animal had to be in agony, had to be panicked, had to be terrified.

And it hit him. Fifteen years old, it hit him like a ton of bricks.

It wasn't just this zebra, of course. It was almost all zebras-and Thomson's gazelles and wildebeests and giraffes.

And it wasn't just Africa.

It was almost all prey animals anywhere in the world.

Animals didn't die of old age. They didn't quietly expire after long, pleasant lives. They didn't pa.s.s on unaided.

No.

They were torn apart, often limb from limb, hemorrhaging severely, usually still conscious, still aware, still sensing.

Death was a horrible, vicious act, almost without exception. Kyle's grandfather had pa.s.sed away the year before. Kyle had never really thought about getting old himself, but suddenly the litany of terms he'd heard his parents bat about during Granddad's illness came back to him.

Heart disease.

Osteoporosis.

Prostate cancer.

Cataracts.

Senility.

Throughout all of history, most people had died horrible deaths, too. Humans had generally not lived long enough to experience old age; evolution, which, as he'd learned in school, had fine-tuned so much of human physiology, had simply had no opportunity to address these problems because almost no one in previous generations had lived long enough to experience them.

The zebra gutted by the lion.

The rat swallowed whole by the snake.

The paralyzed insect that felt itself being eaten alive from within by implanted larvae.

All of them surely aware of what was happening to them.

All of them tortured.

No quick deaths.

No merciful merciful deaths. deaths.

Kyle had put down the remote after that, his interest in catching a glimpse of naked b.r.e.a.s.t.s gone. He'd gone to bed, but had lain awake for hours.

From that night on, whenever he tried to think of G.o.d, he found himself thinking instead of the zebra, its blood staining the water hole.

And to this day, try as he might, he'd been unable to repress that memory.

Heather still wasn't able to sleep. She got up off the couch, went to the closet in the bedroom and found some old photo alb.u.ms; for the last ten years or so, she'd taken only filmless electronic photos, but all of her early memories were stored as prints.

She sat back down on the couch, one leg tucked up underneath her. She opened one of the alb.u.ms, spread it on her lap.

The pictures were from fifteen or so years ago-the turn of the century. The old house on Merton. G.o.d, how she missed that place.

She flipped a page. The photos were under acetate, held in place by a slight adhesive on the backing sheets.

Becky's fifth birthday party-the last one they'd had in the Merton house. Balloons clinging to the wall with static electricity. Becky's friends Jasmine and Brandi-such sophisticated names for such little girls!-playing pin the tail on the donkey.

Of course, that was the party that Heather's sister, Doreen, had failed to show up at-Becky was crushed that her aunt hadn't made it. Heather was still angry about that; she'd bent over backward making a fuss for Doreen's children's birthdays, baking cakes, picking out gifts, and more. But Doreen had been too busy, begging off because some better offer had come along . . .

She turned the page again and- Well, fancy that.

More pictures from the party.

And there was Doreen. She had shown up after all.

Heather peeled up the acetate sheet; it made a sucking sound as it pulled away from the adhesive backing. She then removed the print and read the caption she'd written on the back: "Becky's 5th B-Day." And just in case there was any doubt, there was the date printed by the photofinisher, two days after Rebecca's actual birthday.

She'd been mad at Doreen for a decade and a half over this. Doreen must have originally said she wasn't coming, but had actually shown up at the last minute. Heather had remembered the first part, but had completely forgotten the second.

But there was the photograph: Doreen crouching down next to Becky.

Photos didn't lie.

Heather exhaled.

Memory was was an imperfect process. Of course, the photos reminded her of things. But they were also telling her things she'd never known, or had completely forgotten. an imperfect process. Of course, the photos reminded her of things. But they were also telling her things she'd never known, or had completely forgotten.

And yet, how many rolls of film had she ever shot? Maybe a couple of hundred-meaning that scattered about in photo alb.u.ms and s...o...b..xes, there were a few thousand still frames from her life. Of course there were some home videos, too, and the electronic snapshots she'd saved to disk.

And there were diaries, and copies of old correspondence.

And little mementos and souvenirs that brought to mind events long past.

But that was it. The rest was stored nowhere else but in her fallible brain.

She closed the alb.u.m. The word "Memories" was stamped in gold foil on its beige vinyl cover, but the gold was flaking off.

She looked across the room, down the hallway.

Her computer was down there; when he'd still lived here, Kyle's had been in the bas.e.m.e.nt.

They had practiced safe computing. Every morning when she went to work, she had a memory wafer in her purse containing the previous night's backup of Kyle's optical drive; the drive itself was almost crash-proof, but off-site storage was the only real insurance against loss due to fire or theft. Kyle, likewise, had always taken a memory wafer to his lab with Heather's backup on it.

But what of real value was on their home computers? Financial records, all of which could be reconstructed with some effort. Correspondence, most of it utterly ephemeral. Student grades and other work-related stuff, which all could be redone, if need be.

But for the most important events of their lives, there were no backups, no archives.

Her gaze fell on the stereo cabinet. On top of it sat some framed photographs-of herself, of Kyle, of Becky, and yes, of Mary.

What had really gone on?

If only there were an archive of our memories-some infallible record of everything that had ever happened.

Irrefutable proof, one way or the other.

She closed her eyes.

If only.

9.

Kyle had a huge demonstration coming up; it was vitally important to the continued funding of his research project. He should have been worrying about that-but he wasn't. Instead, as always these days, he was preoccupied with Becky's accusation.

So far, besides Heather and Zack, he'd spoken about it with no one except Cheetah. The only person he'd confided in wasn't a person at all; he might as well have unburdened himself to Mr. Coffee.

Kyle needed to talk this over with somebody really really human. He thought long and hard about whom he could confide in. No one in the Computer Science Department would do; he wanted to leave that pristine, except for his locked talks with Cheetah. In the months ahead, his lab might be the only haven he would know. human. He thought long and hard about whom he could confide in.

Mullin Hall was right next door to the Newman Centre, which housed the Roman Catholic Chaplaincy at U of T. Kyle thought briefly about speaking to the chaplain, but that wouldn't do, either. The pattern was completely different, but a ca.s.sock was black and white. Just like a zebra's hide.

And then it hit him.

The perfect person.

Kyle didn't know him well, but they'd served on three or four committees together over the years, and they'd eaten lunch together, or at least as part of the same group, in the Faculty Club from time to time.

Kyle picked up his office phone and spoke the name he wanted. "Internal directory: Bentley, Stone."

The phone bleeped, then a reedy voice came on. "h.e.l.lo?"

"Stone? It's Kyle Graves."

"Who? Oh-Kyle, sure. Hi."

"Stone, I wonder if you might be free for drinks tonight."

"Uh, okay. Sure. The Faculty Club?"

"No, no. Somewhere off campus."

"How about The Water Hole, on College Street?" said Stone. "Know it?"

"I've walked past it before."

"You'll be coming from Mullin?"

"That's right."

"Stop by my office at five. Persaud Hall, Room Two Twenty-two-just like the old TV show. It's on the way."

"I'll be there."

Kyle clicked off, wondering what exactly he'd say to Stone.

Heather entered her office at U of T. It wasn't huge, but at least universities had never adopted cubicles for their academics. Normally, she shared the office with Omar Amir-another a.s.sociate prof-but he spent all of July and August at his family's cottage in the Kawarthas. So, for the summer at least, she had total privacy in which to think and work. Indeed, although some of the newer offices had frosted-gla.s.s panes running floor-to-ceiling next to their thin doors, Heather and Omar's office was an old fas.h.i.+oned inner sanctum, with a solid wooden door that squeaked on hinges, and a window that looked east, out over the concrete courtyard between Sid Smith and St. George Street. It also had drapes, once probably a rich burgundy but now a pale brown. In the morning, they had to be drawn to s.h.i.+eld her from the rising sun.

Yesterday's alien radio message was still displayed on her monitor. Since the interval between the beginnings of successive messages was thirty hours and fifty-one minutes, every message began almost eight hours later in the day than the one before. The most recent message had been received at 4:54 AM., Eastern time Wednesday; today's was expected to begin at 11:45 A.M. The messages were picked up by different nations' radio telescopes, depending on what part of Earth happened to be pointing at Alpha Centauri at the appropriate time, but they were all posted as they were received to the World Wide Web. An additional orbital receiver was also always aimed at Alpha Centauri.

Heather kept hoping that one day she would look at the latest message and it would all make sense. She missed the simplicity of the first eleven messages: straightforward representations of the Pythagorean theorem and chemical formulas and planetary systems. Although, she had to admit, even those posed some puzzles: the chemicals specified by the formulas had been synthesized on Earth, but no one had ever figured out what they were for.

Heather got herself a mug of coffee and sat down to look again at yesterday's message.

As always, the message was shown as two rectangular grids. Each message was sent as a string of a hundred thousand or so binary digits, over a period of two or three hours. The total number of digits in each message was always the product of two prime numbers, meaning that the digits could be arrayed in two possible ways. According to the header from the Alien Signal Center in Karachi, Pakistan, this message was 108,197 bits long. That number was the product of the prime numbers 257 and 421, which meant that the digits could be set up either as 257 rows of 421 columns or as 421 rows of 257 columns. Sometimes one image looked more intuitively correct than the other-squares or circles would appear in one, while the alternative decoding would simply result in a mishmash. But since no one had yet determined what the messages were supposed to represent, one couldn't be certain which was really the correct interpretation.

When the messages had first started arriving in 2007, millions of people had pored over each one. But as the years had pa.s.sed, the numbers had reduced. Although there was a popular screensaver that downloaded each day's message from the aliens and magnified various portions of it in turn, Heather knew there were now fewer than three hundred researchers actively a.n.a.lyzing each new message.

The more correct-looking version of today's message showed three rectangles and two circles in what otherwise seemed to be a random sea of black-and-white squares; the black squares represented zero bits and the white squares represented ones. Heather stared at it, frustrated. She felt sure she had to be missing something simple. Somewhere in the hundreds of millions of bits of data already received from Alpha Centauri there must have been a Rosetta stone-a key that would let all the other messages make sense.

There were dissenting views: one researcher in Portugal had long argued that the key would come as the final message, not as one of the initial ones; that way, the aliens would automatically weed out any races that lacked the patience required for interstellar communication. And others had opined that the alien senders were simply too too alien-that we were incapable of communicating. A third camp argued that humanity simply wasn't bright enough, or advanced enough, to figure out what was being said. The aliens might indeed still be on what they considered basics, but the material had already gone over the collective head of humanity. alien-that we were incapable of communicating.

Heather was a Jungian psychologist. She believed that all human minds shared a vocabulary of symbols and archetypes that formed the underpinnings of thought. The Centaurs, she felt sure, simply had a different set of underlying metaphors and symbols, and if she could figure out what those were, she could crack the code.

She took a sip of coffee. This message was as baffling as the others. Maybe it was all a giant crossword puzzle, she thought. The grids of black-and-white squares certainly suggested that, although filling in the blanks was a human concept, possibly-if she could wax Freudian for a moment-related to our s.e.xual biology. Still, it wasn't the first time she'd wondered if the messages might be deliberately incomplete-yin, but no yang-and the aliens were waiting for humanity to provide the complement, to make it all whole.
