Mark Askwith

Master of Multiple Universes

For anthropological and paleontological advice, I thank Milford H. Wolpoff, Ph.D., University of Michigan; Ian Tattersall, Ph.D., and Gary J. Sawyer (no relation), both of the American Museum of Natural History; Philip Lieberman, Ph.D., Brown University; Michael K. Brett-Surman, Ph.D., and Rick Potts, Ph.D., both of the National Museum of Natural History, Smithsonian Institution; Robin Ridington, Ph.D., Professor Emeritus, University of British Columbia; and the various experts listed in the Acknowledgments to my previous book,
Hominids
.

Special thanks to Art McDonald, Ph.D., Director, Sudbury Neutrino Observatory Institute, and J. Duncan Hepburn, Ph.D., site manager, Sudbury Neutrino Observatory. Thanks, too, to Sudbury resident Kris Holland, who went over the manuscript with a fine-toothed comb.

Huge thanks to my lovely wife, Carolyn Clink; my editor, David G. Hartwell, and his associate, Moshe Feder; my agent, Ralph Vicinanza, and his associates, Christopher Lotts and Vince Gerardis; Tom Doherty, Linda Quinton, Jennifer Marcus, Jennifer Hunt, and everyone else at Tor Books; Harold and Sylvia Fenn, Robert Howard, Heidi Winter, Melissa Cameron, David Leonard, and everyone else at H. B. Fenn and Company; and my colleagues, Terence M. Green, Andrew Weiner, and Robert Charles Wilson.

Special thanks to Byron R. Tetrick, whose invitation to contribute to his landmark 2002 anthology,
In the Shadow of the Wall: Vietnam Stories That Might Have Been
(Cumberland House), led to me focusing my thoughts on several key issues; much of Chapter 22, in a different form, first appeared in that anthology.

Beta testers for this novel were the always insightful Ted Bleaney, Michael A. Burstein, David Livingstone Clink, Marcel Gagné, Richard Gotlib, Peter Halasz, Howard Miller, Dr. Ariel Reich, Alan B. Sawyer, and Sally Tomasevic, and I was fortunate enough to be working again with the copyediting team of Bob and Sara Schwager.

Parts of this book were written at John A. Sawyer’s vacation home on Canandaigua Lake—thanks, Dad! Thanks, also, to Nicholas A. DiChario, my host on frequent visits to Rochester, New York, where some of this novel is set.

York University, the Sudbury Neutrino Observatory, and the Creighton Mine all really exist. However, all the characters in this novel are entirely the product of my imagination. They are not meant to bear any resemblance to the actual people who hold or have held positions with these or any other organizations.

If only there were evil people somewhere

insidiously committing evil deeds and it were

necessary only to separate them from the rest

of us and destroy them. But the line

dividing good and evil cuts through the heart

of every human being. And who is willing to

destroy a piece of his own heart?

“I’ve done a terrible thing,” said Ponter Boddit, straddling the saddle seat in Jurard Selgan’s office.

Selgan was a member of generation 144, ten years older than Ponter. His hair was a wise gray, and his part had widened into a deep river of scalp, emptying onto the low forehead above his browridge. “Go on.”

“I felt I had no choice,” said Ponter, looking down, his own browridge shielding him from having to meet Selgan’s emerald eyes. “I felt I
had
to do it, but…”

“But you regret it now?”

Ponter was silent, staring at the room’s moss-covered floor.

“Do
you regret it?”

“I—I’m not sure.”

“Would you do it again, if you had the moment to live over?”

Ponter snorted a laugh.

“What’s so funny?” asked Selgan, curiosity, rather than irritation, in his voice.

Ponter looked up. “I thought it was only physicists like me who engaged in thought experiments.”

Selgan smiled. “We’re not so different, you and I. We each seek to find the truth, to solve mysteries.”

“I suppose,” said Ponter. He looked at the smooth, gently curving wooden wall of the cylindrical room.

“You haven’t answered my question,” said Selgan. “Would you do it again, if you could?”

Ponter was silent for a time, and Selgan let him be silent, let him consider his answer. “I don’t know,” Ponter said at last.

“Don’t you? Or is it that you simply do not wish to say?”

Again, Ponter was silent.

“I want to help you,” said Selgan, shifting on his own saddle-seat. “That’s my only goal. I won’t judge you.”

Ponter laughed again, but this time it was a rueful laugh. “That’s the whole point, isn’t it?
Nobody
judges us.”

Selgan frowned. “What do you mean?”

“I mean, in that other world—that other Earth—they believe there is a…well, we have no word for it, but they call it
God.
A supreme, incorporeal being who created the universe.”

Selgan shook his head. “How can the universe have a creator? For something to be created, it has to have a beginning. And the universe didn’t. It has always existed.”

“You know that,” said Ponter. “I know that. But
they
don’t know that. They think the universe is only—well, they’d say twelve billion years old; a hundred and fifty billion months or so.”

“Then what existed
before
that time?”

Ponter frowned, remembering back to his conversations with the female Gliksin physicist Lou Benoît—how he wished he could pronounce their names properly! “They say there was
no
time before then, that time began when the universe was created.”

“What an astonishing notion,” said Selgan.

“That it is,” agreed Ponter. “But if they accepted that the universe had always existed, there would be no role for this God of theirs.”

“Your man-mate is a physicist, isn’t he?” asked Selgan.

“Adikor Huld,” said Ponter, naming him. “Yes.”

“Well, I’m sure you often get to talk about physics with Adikor. Me, I’m more interested in other things. You brought up this—this ‘God’—in connection with the concept of judging. Tell me more about that.”

Ponter was quiet for a few moments, trying to figure out how to present the concept. “It seems most of them, these other humans, believe in what they call an ‘afterlife’—an existence that follows death.”

“But that’s ridiculous,” said Selgan. “It’s a contradiction in terms.”

“Oh, yes,” said Ponter, smiling. “But such things are common in their thinking—so common that they give them a special name, as if by naming them it resolves the paradox. I can’t quite say it the way they do; it’s something like
ox-uh-mor-on.”

Selgan smiled. “I would love to treat one of them—learn how such a mind functions.” He paused. “This existence that follows death: what do they believe it is like?”

“That’s the most interesting thing,” said Ponter. “It can take one of two forms, depending on how you comported yourself while living. If you have lived a virtuous life, then you are rewarded with an exceedingly pleasant existence afterward. But if your life—or even a single major action you did during it—has been evil, then the subsequent existence is one of torment.”

“And who decides?” said Selgan. “Oh, wait. I get it. This God decides, right?”

“Yes. That’s what they believe.”

“But why? Why would they believe something so outlandish?”

Ponter lifted his shoulders slightly. “Supposed historical accounts of those who have communicated with this God.”

“Historical
accounts?” said Selgan. “Does anyone currently communicate with this God?”

“Some claim to. But I gather it has not been substantiated.”

“And this God, he serves as judge of every individual?”

“Supposedly.”

“But there are 185 million people in the world, with many thousands dying every day.”

“That’s in
this
world. In the other world, there are over six billion people.”

“Six billion!” Selgan shook his head. “And each one is assigned, somehow, at death, to one of the two possible further existences you mentioned?”

“Yes. They are judged.”

Ponter saw Selgan make a face. The personality sculptor was clearly intrigued by the details of Gliksin belief, but his real interest was in Ponter’s thoughts. “‘Judged,’” he repeated, as if the word were a choice piece of meat worth savoring.

“Yes, judged,” said Ponter. “Don’t you see? They don’t have Companion implants. They don’t have alibi archives. They don’t keep perfect records of every action they take in their lives. They don’t have any of that, because they don’t believe they need it. They think this God is watching over all, seeing all—even looking out for them, protecting them. And they think that it’s impossible to get away—to
really,
ultimately—get away with an evil act.”

“But you did something terrible, you said?”

Ponter looked out the window, out at his world. “Yes.”

“Over there? In the other world?”

“Yes.”

“And you do not accept the existence of this God of theirs?”

Ponter made a derisive sound. “Of course not.”

“And so you believe that you will not ever be judged for this bad thing you feel you did?”

“Exactly. I won’t say it’s the perfect crime. But there is no reason why suspicion will ever fall on me in that world, and no reason why anyone here would ever have cause to demand to see that portion of my alibi archive.”

“You called it a crime. Was it a crime by the standards of this other world you were in?”

“Oh, yes.”

“And would
we
have considered it a crime, had you done it here?”

Ponter nodded.

“What did you do?”

“I—I am ashamed to say,” said Ponter.

“I told you, I will not judge you.”

Ponter found himself surging to his feet. “That’s the whole point!” he shouted.
“No one
will judge me—not here, not there. I have committed a crime. I
enjoyed
committing the crime. And, yes, to indulge in your thought experiment, I would do it again if I had the opportunity to relive the event.”

Selgan said nothing for a time, apparently waiting for Ponter to calm down. “I can help you, Ponter, if you’ll let me. But you have to talk to me. You have to tell me what happened. Why did you commit this crime? What led up to it?”

Ponter sat back down, swinging his legs over the saddle-seat. “It began on my first trip to the other Earth,” said Ponter. “I met a woman there, named Mare Vaughan…”
