Time Travel Omnibus, page 637
This made a problem for time, or Time, which is neither like a rubber band nor like a spring; nor even like a river nor a carrier wave—but which, like all of these things, can be deformed by certain stresses. For instance, two people going into the future and three coming back on the same time-casting beam.
In an earlier age, when time travel was more common, time-casters would have made sure that the baby, or at least its aborted embryo, would stay in the future when the mother returned to her present. Or they could arrange for the mother to stay in the future.
But these subtleties had long been forgotten when Nine-hover relearned the dead art. So Sarah went back to her present with a hitch-hiker, an interloper, firmly imbedded in the lining of her womb. And its dim sense of life set up a kind of eddy in the flow of time, that Sarah had to share.
The mathematical explanation is subtle, and can’t be comprehended by those of us who synapse with fewer than four degrees of freedom. But the end effect is clear: Sarah had to experience all of her own life backwards, all the way back to that embrace on the beach.
Some highlights were:
In 1992, slowly dying of cancer, in a mental hospital.
In 1979, seeing Bob finally succeed at suicide on the American Plan, not quite finishing his 9,527th bottle of liquor.
In 1970, having her only son returned in a sealed casket from a country she’d never heard of.
In the 1960’s, helplessly watching her son become more and more neurotic because of something that no one could name.
In 1953, Bob coming home with one foot, the other having been lost to frostbite; never having fired a shot in anger.
In 1952, the agonizing breech presentation.
Like her son, Sarah would remember no details of the backward voyage through her life. But the scars of it would haunt her forever.
They were kissing on the beach.
Sarah dropped the blanket and made a little noise. She started crying and slapped Bob as hard as she could, then ran on alone, up to the cabin.
Bob watched her progress up the hill with mixed feelings. He took a healthy slug from the bourbon bottle, to give him an excuse to wipe his own eyes.
He could go sit on the beach and finish the bottle; let her get over it by herself. Or he could go comfort her.
He tossed the bottle away, the gesture immediately making him feel stupid, and followed her. Later that night she apologized, saying she didn’t know what had gotten into her.
GIBRALTAR FALLS
Poul Anderson
The Time Patrol base would only remain for the hundred-odd years of inflow. During that while, few people other than scientists and maintenance crew would stay there for long at a stretch. Thus it was small, a lodge and a couple of service buildings, nearly lost in the land.
Five and a half million years before he was born, Tom Nomura found that southern end of Iberia still more steep than he remembered it. Hills climbed sharply northward until they became low mountains walling the sky, riven by canyons where shadows lay blue. It was dry country, rained on violently but briefly in winter, its streams shrunken to runnels or nothing as its grass burnt yellow in summer. Trees and shrubs grew far apart, thorn, mimosa, acacia, pine, aloe; around the water holes palm, fern, orchid.
Withal, it was rich in life. Hawks and vultures were always at hover in cloudless heaven. Grazing herds mingled their millions together; among their scores of kinds were zebra-striped ponies, primitive rhinoceros, okapi-like ancestors of the giraffe, sometimes mastodon—thinly red-haired, hugely tusked—or peculiar elephants. Among the predators and scavengers were sabertooths, early forms of the big cats, hyenas, and scuttering ground apes which occasionally walked on their hind legs. Ant heaps lifted six feet into the air. Marmots whistled.
It smelled of hay, scorch, baked dung and warm flesh. When wind awoke, it boomed, pushed, threw dust and heat into the face. Often the earth resounded to hoofbeats, birds clamored or beasts trumpeted. At night a sudden chill struck down, and the stars were so many that one didn’t much notice the alienness of their constellations.
Thus had things been until lately. And as yet there was no great change. But now had begun a hundred years of thunder. When that was done, nothing would ever be the same again.
Manse Everard regarded Tom Nomura and Feliz a Rach for a squinting moment before he smiled and said, “No, thanks, I’ll just poke around here today. You go have fun.”
Did an eyelid of the big, bent-nosed, slightly grizzled man droop a little in Nomura’s direction? The latter couldn’t be sure. They were from the same milieu, indeed the same country. That Everard had been recruited in New York, A.D. 1954, and Nomura in San Francisco, 1972, ought to make scant difference. The upheavals of that generation were bubble pops against what had happened before and what would happen after. However, Nomura was fresh out of the Academy, a bare twenty-five years of lifespan behind him. Everard hadn’t told how much time his own farings through the world’s duration added up to; and given the longevity treatment the Patrol offered its people, it was impossible to guess. Nomura suspected the Unattached agent had seen enough existence to have become more foreign to him than Feliz—who was born two millenniums past either of them.
“Very well, let’s start,” she said. Curt though it was, Nomura thought her voice made music of the Temporal language.
They stepped from the veranda and walked across the yard. A couple of other corpsmen hailed them, with a pleasure directed at her. Nomura agreed. She was young and tall, the curve-nosed strength of her features softened by large green eyes, large mobile mouth, hair that shone auburn in spite of being hacked off at the ears. The usual gray coverall and stout boots could not hide her figure or the suppleness of her stride. Nomura knew he himself wasn’t bad-looking—a stocky but limber frame, high-cheeked regular features, tawny skin—but she made him feel drab.
Also inside, he thought. How does a new-minted Patrolman—not even slated for police duty, a mere naturalist—how does he tell an aristocrat of the First Matriarchy that he’s fallen in love with her?
The rumbling which always filled the air, these miles from the cataracts, sounded to him like a chorus. Was it imagination, or did he really sense an endless shudder through the ground, up into his bones?
Feliz opened a shed. Several hoppers stood inside, vaguely resembling wheelless two-seater motorcycles, propelled by antigravity and capable of leaping across several thousand years. (They and their present riders had been transported hither in heavy-duty shuttles.) Hers was loaded with recording gear. He had failed to convince her it was overburdened and knew she’d never forgive him if he finked on her. His invitation to Everard—the ranking officer in hand, though here-now simply on vacation—to join them today had been made in a slight hope that the latter would see that load and order her to let her assistant carry part of it.
She sprang to the saddle. “Come on!” she said. “The morning’s getting old.”
He mounted his vehicle and touched controls. Both glided outside and aloft. At eagle height, they leveled off and bore south, where the River Ocean poured into the Middle of the World.
Banks of upflung mist always edged that horizon, argent smoking off into azure. As one drew near afoot, they loomed topplingly overhead. Farther on, the universe swirled gray, shaken by the roar, bitter on human lips, while water flowed off rock and gouged through mud. So thick was the cold salt fog that it was unsafe to breathe for more than a few minutes.
From well above, the sight was yet more awesome. There one could see the end of a geological epoch. For a million and a half years the Mediterranean basin had lain a desert. Now the Gates of Hercules stood open and the Atlantic was coming through.
The wind of his passage around him, Nomura peered west across unrestful, many-hued and intricately foam-streaked immensity. He could see the currents run, sucked toward the new-made gap between Europe and Africa. There they clashed together and recoiled, a white and green chaos whose violence toned from earth to heaven and back, crumbled cliffs, overwhelmed valleys, blanketed the shore in spume for miles inland. From them came a stream, snow-colored in its fury, with flashes of livid emerald, to stand in an eight-mile wall between the continents and bellow. Spray roiled aloft, dimming the torrent after torrent wherein the sea crashed onward.
Rainbows wheeled through the clouds it made. This far aloft, the noise was no more than a monstrous millstone grinding. Nomura could clearly hear Feliz’s voice out of his receiver, as she stopped her vehicle and lifted an arm. “Hold. I want a few more takes before we go on.”
“Haven’t you enough?” he asked.
Her words softened. “How can we get enough of a miracle?”
His heart jumped. She’s not a she-soldier, born to lord it over a ruck of underlings. In spite of her early life and ways, she isn’t. She feels the dread, the beauty, yes, the sense of God at work—
A wry grin at himself: She’d better!
After all, her task was to make a full-sensory record of the whole thing, from its beginning until that day when, a hundred years hence, the basin was full and the sea lapped calm where Odysseus would sail. It would take months of her lifespan. (And mine, please, mine.) Everybody in the corps wanted to experience this stupendousness; the hope of adventure was practically required for recruitment. But it wasn’t feasible for many to come so far downstairs, crowding into so narrow a time-slot. Most would have to do it vicariously. Their chiefs would not have picked someone who was not a considerable artist, to live it on their behalf and pass it on to them.
Nomura remembered his astonishment when he was assigned to assist her. Short-handed as it was, could the Patrol afford artists?
Well, after he answered a cryptic advertisement and took several puzzling tests and learned about intertemporal traffic, he had wondered if police and rescue work were possible and been told that, usually, they were. He could see the need for administrative and clerical personnel, resident agents, historiographers, anthropologists, and, yes, natural scientists like himself. In the weeks they had been working together, Feliz convinced him that a few artists were at least as vital. Man does not live by bread alone, nor guns, paperwork, theses, naked practicalities.
She restowed her apparatus. “Come,” she ordered. As she flashed eastward ahead of him, her hair caught a sunbeam and shone as if molten. He trudged mute in her wake.
The Mediterranean floor lay ten thousand feet below sea level. The inflow took most of that drop within a fifty-mile strait. Its volume amounted to ten thousand cubic miles a year, a hundred Victoria Falls or a thousand Niagaras.
Thus the statistics. The reality was a roar of white water, spray-shrouded, earth-sundering, mountain-shaking. Men could see, hear, feel, smell, taste the thing; they could not imagine it.
When the channel widened, the flow grew smoother, until it ran green and black. Then mists diminished and islands appeared, like ships which cast up huge bow waves; and life could again grow or go clear to the shore. Yet most of those islands would be eroded away before the century was out, and much of that life would perish in weather turned strange. For this event would move the planet from its Miocene to its Pliocene epoch.
And as he flitted onward, Nomura did not hear less noise, but more. Though the stream itself was quieter here, it moved toward a bass clamor which grew and grew till heaven was one brazen bell. He recognized a headland whose worn-down remnant would someday bear the name Gibraltar. Not far beyond, a cataract twenty miles wide made almost half the total plunge.
With terrifying ease, the waters slipped over that brink. They were glass-green against the darkling cliffs and umber grass of the continents. Light flamed off their heights. At their bottom another cloud bank rolled white in never-ending winds. Beyond reached a blue sheet, a lake whence rivers hewed canyons, out and out across the alkaline sparkle, dust devils, and mirage shimmers of the furnace land which they would make into a sea.
It boomed, it brawled, it querned.
Again Feliz poised her flyer. Nomura drew alongside. They were high; the air whittered chilly around them.
“Today,” she told him, “I want to try for an impression of the sheer size. I’ll move in close to the top, recording as I go, and then down.”
“Not too close,” he warned.
She bridled. “I’ll judge that.”
“Uh, I . . . I’m not trying to boss you or anything.” I’d better not. I, a plebe and a male. “As a favor, please—” Nomura flinched at his own clumsy speech. “—be careful, will you? I mean, you’re important to me.”
Her smile burst upon him. She leaned hard against her safety harness to catch his hand. “Thank you, Tom.” After a moment, turned grave: “Men like you make me understand what is wrong in the age I come from.”
She had often spoken kindly to him: most times, in fact. Had she been a strident militant, no amount of comeliness would have kept him awake nights. He wondered if perhaps he had begun loving her when first he noticed how conscientiously she strove to regard him as her equal. It was not easy for her, she being almost as new in the Patrol as he—no easier than it was for men from other areas to believe, down inside where it counted, that she had the same capabilities they did and that it was right she use herself to the full.
She couldn’t stay solemn. “Come on!” she shouted. “Hurry! That straight dropoff won’t last another twenty years!”
Her machine darted. He slapped down the face screen of his helmet and plunged after, bearing the tapes and power cells and other auxiliary items. Be careful, he pleaded, oh, be careful, my darling.
She had gotten well ahead. He saw her like a comet, a dragonfly, everything vivid and swift, limned athwart yonder mile-high precipice of sea. The noise grew in him till there was nothing else, his skull was full of its doomsday.
Yards from the waters, she rode her hopper chasmward. Her head was buried in a dial-studded box, her hands at work on its settings; she steered with her knees. Salt spray began to fog Nomura’s screen. He activated the self-cleaner. Turbulence clawed at him; his carrier lurched. His eardrums, guarded against sound but not changing pressure, stabbed with pain.
He had come quite near Feliz when her vehicle went crazy. He saw it spin, saw it strike the green immensity, saw it and her engulfed. He could not hear himself scream through the thunder.
He rammed the speed switch, swooped after her. Was it blind instinct which sent him whirling away again, inches before the torrent grabbed him too? She was gone from sight. There was only the water wall, clouds below and unpitying blue calm above, the noise that took him in its jaws to shake him apart, the cold, the damp, the salt on his mouth that tasted like tears.
He fled for help.
Noonday glowered outside. The land looked bleached, lay moveless and lifeless except for a carrion bird. The distant falls alone had voice.
A knock on the door of his room brought Nomura off the bed, onto his feet. Through an immediately rackety pulse he croaked, “Come in. Do.”
Everard entered. In spite of air conditioning, sweat spotted his garments. He gnawed a fireless pipe and his shoulders slumped.
“What’s the word?” Nomura begged of him.
“As I feared. Nothing. She never returned home.”
Nomura sank into a chair and stared before him. “You’re certain?”
Everard sat down on the bed, which creaked beneath his weight. “Yeah. The message capsule just arrived. In answer to my inquiry, et cetera, Agent Feliz a Rach has not reported back to her home milieu base from the Gibraltar assignment, and they have no further record of her.”
“Not in any era?”
“The way agents move around in time and space, nobody keeps dossiers, except maybe the Danellians.”
“Ask them!”
“Do you imagine they’d reply?” Everard snapped—they, the supermen of the remote future who were the founders and ultimate masters of the Patrol. One big fist clenched on his knee. “And don’t tell me we ordinary mortals could keep closer tabs if we wanted to. Have you checked your personal future, son? We don’t want to, and that’s that.”
The roughness left him. He shifted the pipe about in his grip and said most gently, “If we live long enough, we outlive those we’ve cared for. The common fate of man; nothing unique to our corps. But I’m sorry you had to strike it so young.”
“Never mind me!” Nomura exclaimed. “What of her?”
“Yes . . . I’ve been thinking about your account. My guess is, the airflow patterns are worse than tricky around that fall. What should’ve been expected, no doubt. Overloaded, her hopper was less controllable than usual. An air pocket, a flaw, whatever it was, something like that grabbed her without warning and tossed her into the stream.”
Nomura’s fingers writhed against each other. “And I was supposed to look after her.”
Everard shook his head. “Don’t punish yourself worse. You were simply her assistant. She should have been more careful.”
“But—God damn it, we can rescue her still, and you won’t allow us to?” Nomura half screamed.
“Stop,” Everard warned. “Stop right there.”
Never say it: that several Patrolmen could ride backward in time, lay hold on her with tractor beams and haul her free of the abyss. Or that I could tell her and my earlier self to beware. It did not happen, therefore it will not happen.
It must not happen.
For the past becomes in fact mutable, as soon as we on our machines have transformed it into our present. And if ever a mortal takes himself that power, where can the changing end? We start by saving a glad girl; we go on to save Lincoln, but somebody else tries to save the Confederate States—No, none less than God can be trusted with time. The Patrol exists to guard what is real. Its men may no more violate that faith than they may violate their own mothers.
“I’m sorry,” Nomura mumbled.
“It’s okay, Tom.”
“No, I . . . I thought . . . when I saw her vanish, my first thought was that we could make up a party, ride back to that very instant and snatch her clear—”
In an earlier age, when time travel was more common, time-casters would have made sure that the baby, or at least its aborted embryo, would stay in the future when the mother returned to her present. Or they could arrange for the mother to stay in the future.
But these subtleties had long been forgotten when Nine-hover relearned the dead art. So Sarah went back to her present with a hitch-hiker, an interloper, firmly imbedded in the lining of her womb. And its dim sense of life set up a kind of eddy in the flow of time, that Sarah had to share.
The mathematical explanation is subtle, and can’t be comprehended by those of us who synapse with fewer than four degrees of freedom. But the end effect is clear: Sarah had to experience all of her own life backwards, all the way back to that embrace on the beach.
Some highlights were:
In 1992, slowly dying of cancer, in a mental hospital.
In 1979, seeing Bob finally succeed at suicide on the American Plan, not quite finishing his 9,527th bottle of liquor.
In 1970, having her only son returned in a sealed casket from a country she’d never heard of.
In the 1960’s, helplessly watching her son become more and more neurotic because of something that no one could name.
In 1953, Bob coming home with one foot, the other having been lost to frostbite; never having fired a shot in anger.
In 1952, the agonizing breech presentation.
Like her son, Sarah would remember no details of the backward voyage through her life. But the scars of it would haunt her forever.
They were kissing on the beach.
Sarah dropped the blanket and made a little noise. She started crying and slapped Bob as hard as she could, then ran on alone, up to the cabin.
Bob watched her progress up the hill with mixed feelings. He took a healthy slug from the bourbon bottle, to give him an excuse to wipe his own eyes.
He could go sit on the beach and finish the bottle; let her get over it by herself. Or he could go comfort her.
He tossed the bottle away, the gesture immediately making him feel stupid, and followed her. Later that night she apologized, saying she didn’t know what had gotten into her.

Everard sat down on the bed, which creaked beneath his weight. “Yeah. The message capsule just arrived. In answer to my inquiry, et cetera, Agent Feliz a Rach has not reported back to her home milieu base from the Gibraltar assignment, and they have no further record of her.”
“Not in any era?”
“The way agents move around in time and space, nobody keeps dossiers, except maybe the Danellians.”
“Ask them!”
“Do you imagine they’d reply?” Everard snapped—they, the supermen of the remote future who were the founders and ultimate masters of the Patrol. One big fist clenched on his knee. “And don’t tell me we ordinary mortals could keep closer tabs if we wanted to. Have you checked your personal future, son? We don’t want to, and that’s that.”
The roughness left him. He shifted the pipe about in his grip and said most gently, “If we live long enough, we outlive those we’ve cared for. The common fate of man; nothing unique to our corps. But I’m sorry you had to strike it so young.”
“Never mind me!” Nomura exclaimed. “What of her?”
“Yes . . . I’ve been thinking about your account. My guess is, the airflow patterns are worse than tricky around that fall. What should’ve been expected, no doubt. Overloaded, her hopper was less controllable than usual. An air pocket, a flaw, whatever it was, something like that grabbed her without warning and tossed her into the stream.”
Nomura’s fingers writhed against each other. “And I was supposed to look after her.”
Everard shook his head. “Don’t punish yourself worse. You were simply her assistant. She should have been more careful.”
“But—God damn it, we can rescue her still, and you won’t allow us to?” Nomura half screamed.
“Stop,” Everard warned. “Stop right there.”
Never say it: that several Patrolmen could ride backward in time, lay hold on her with tractor beams and haul her free of the abyss. Or that I could tell her and my earlier self to beware. It did not happen, therefore it will not happen.
It must not happen.
For the past becomes in fact mutable, as soon as we on our machines have transformed it into our present. And if ever a mortal takes himself that power, where can the changing end? We start by saving a glad girl; we go on to save Lincoln, but somebody else tries to save the Confederate States—No, none less than God can be trusted with time. The Patrol exists to guard what is real. Its men may no more violate that faith than they may violate their own mothers.
“I’m sorry,” Nomura mumbled.
“It’s okay, Tom.”
“No, I . . . I thought . . . when I saw her vanish, my first thought was that we could make up a party, ride back to that very instant and snatch her clear—”
