Sense of Wonder: A Century of Science Fiction (137 page)

“You realize, of course, that the history of civilization on Lagash displays a cyclic character—but I mean
cyclic!
”

“I know,” replied Theremon cautiously, “that that is the current archaeological theory. Has it been accepted as a fact?”

“Just about. In this last century it’s been generally agreed upon. This cyclic character is—or rather, was—one of the great mysteries. We’ve located series of civilizations, nine of them definitely, and indications of others as well, all of which have reached heights comparable to our own, and all of which, without exception, were destroyed by fire at the very height of their culture.

“And no one could tell why. All centers of culture were thoroughly gutted by fire, with nothing left behind to give a hint as to the cause.”

Theremon was following closely. “Wasn’t there a Stone Age, too?”

“Probably, but as yet practically nothing is known of it, except that men of that age were little more than rather intelligent apes. We can forget about that.”

“I see. Go on!”

“There have been explanations of these recurrent catastrophes, all of a more or less fantastic nature. Some say that there are periodic rains of fire; some that Lagash passes through a sun every so often; some even wilder things. But there is one theory, quite different from all of these, that has been handed down over a period of centuries.”

“I know. You mean this myth of the “Stars” that the Cultists have in their
Book of Revelations.
”

“Exactly,” rejoined Sheerin with satisfaction. “The Cultists said that every two thousand and fifty years Lagash entered a huge cave, so that all the suns disappeared, and there came
total darkness all over the world
! And then, they say, things called Stars appeared, which robbed men of their souls and left them unreasoning brutes, so that they destroyed the civilization they themselves had built up. Of course they mix all this up with a lot of religio-mystic notions, but that’s the central idea.”

There was a short pause in which Sheerin drew a long breath. “And now we come to the Theory of Universal Gravitation.” He pronounced the phrase so that the capital letters sounded—and at that point Aton turned from the window, snorted loudly, and stalked out of the room.

* * * *

The two stared after him, and Theremon said, “What’s wrong?”

“Nothing in particular,” replied Sheerin. “Two of the men were due several hours ago and haven’t shown up yet. He’s terrifically short-handed, of course, because all but the really essential men have gone to the Hideout.”

“You don’t think the two deserted, do you?”

“Who? Faro and Yimot? Of course not. Still, if they’re not back within the hour, things would be a little sticky.” He got to his feet suddenly, and his eyes twinkled. “Anyway, as long as Aton is gone—”

Tiptoeing to the nearest window, he squatted, and from the low window box beneath withdrew a bottle of red liquid that gurgled suggestively when he shook it.

“I
thought
Aton didn’t know about this,” he remarked as he trotted back to the table. “Here! We’ve only got one glass so, as the guest, you can have it. I’ll keep the bottle.”

And he filled the tiny cup with judicious care. Theremon rose to protest, but Sheerin eyed him sternly.

“Respect your elders, young man.”

The newsman seated himself with a look of anguish on his face. “Go ahead, then, you old villain.”

The psychologist’s Adam’s apple wobbled as the bottle upended, and then, with a satisfied grunt and a smack of the lips, he began again. “But what do you know about gravitation?”

“Nothing, except that it is a very recent development, not too well established, and that the math is so hard that only twelve men in Lagash are supposed to understand it.”

“
Tcha!
Nonsense! Baloney! I can give you all the essential math in a sentence. The Law of Universal Gravitation states that there exists a cohesive force among all bodies of the universe, such that the amount of this force between any two given bodies is proportional to the product of their masses divided by the square of the distance between them.”

“Is that all?”

“That’s enough! It took four hundred years to develop it.”

“Why that long? It sounded simple enough, the way you said it.”

“Because great laws are not divined by flashes of inspiration, whatever you may think. It usually takes the combined work of a world full of scientists over a period of centuries. After Genovi 4I discovered that Lagash rotated about the sun Alpha rather than vice versa—and that was four hundred years ago—astronomers have been working. The complex motions of the six suns were recorded and analyzed and unwoven. Theory after theory was advanced and checked and counterchecked and modified and abandoned and revived and converted to something else. It was a devil of a job.”

Theremon nodded thoughtfully and held out his glass for more liquor. Sheerin grudgingly allowed a few ruby drops to leave the bottle.

“It was twenty years ago,” he continued after remoistening his own throat, “that it was finally demonstrated that the Law of Universal Gravitation accounted exactly for the orbital motions of the six suns. It was a great triumph.”

Sheerin stood up and walked to the window, still clutching his bottle. “And now we’re getting to the point. In the last decade, the motions of Lagash about Alpha were computed according to gravity, and if
did not account for the orbit observed;
not even when all perturbations due to the other suns were included. Either the law was invalid, or there was another, as yet unknown, factor involved.”

Theremon joined Sheerin at the window and gazed out past the wooded slopes to where the spires of Saro City gleamed bloodily on the horizon. The newsman felt the tension of uncertainty grow within him as he cast a short glance at Beta. It glowered redly at zenith, dwarfed and evil.

“Go ahead, sir,” he said softly.

Sheerin replied, “Astronomers stumbled about for years, each proposed theory more untenable than the one before—until Aton had the inspiration of calling in the Cult. The head of the Cult, Sor 5, had access to certain data that simplified the problem considerably. Aton set to work on a new track.

“What if there were another nonluminous planetary body such as Lagash? If there were, you know, it would shine only by reflected light, and if it were composed of bluish rock, as Lagash itself largely is, then, in the redness of the sky, the eternal blaze of the suns would make it invisible—drown it out completely.”

Theremon whistled. “What a screwy idea!”

“You think
that’s
screwy? Listen to this: Suppose this body rotated about Lagash at such a distance and in such an orbit and had such a mass that its attention would exactly account for the deviations of Lagash’s orbit from theory—do you know what would happen?”

The columnist shook his head.

“Well, sometimes this body would get in the way of a sun.” And Sheerin emptied what remained in the bottle at a draft.

“And it does, I suppose,” said Theremon flatly.

“Yes! But only one sun lies in its plane of revolution.” He jerked a thumb at the shrunken sun above. “Beta! And it has been shown that the eclipse will occur only when the arrangement of the suns is such that Beta is alone in its hemisphere and at maximum distance, at which time the moon is invariably at minimum distance. The eclipse that results, with the moon seven times the apparent diameter of Beta, covers all of Lagash and lasts well over half a day, so that no spot on the planet escapes the effects.
That eclipse comes once every two thousand and forty-nine years.
”

Theremon’s face was drawn into an expressionless mask.

“And that’s my story?”

The psychologist nodded. “That’s all of it. First the eclipse—which will start in three quarters of an hour—then universal Darkness and, maybe, these mysterious Stars—then madness, and end of the cycle.”

He brooded. “We had two months” leeway—we at the Observatory—and that wasn’t enough time to persuade Lagash of the danger. Two centuries might not have been enough. But our records are at the Hideout, and today we photograph the eclipse. The next cycle will
start off
with the truth, and when the
next
eclipse comes, mankind will at last be ready for it. Come to think of it, that’s part of your story too.”

A thin wind ruffled the curtains at the window as Theremon opened it and leaned out. It played coldly with his hair as he stared at the crimson sunlight on his hand. Then he turned in sudden rebellion.

“What is there in Darkness to drive
me
mad?”

Sheerin smiled to himself as he spun the empty liquor bottle with abstracted motions of his hand. “Have you ever experienced Darkness, young man?”

The newsman leaned against the wall and considered. “No. Can’t say I have. But I know what it is. Just—uh—“ He made vague motions with his fingers and then brightened. “Just no light. Like in caves.”

“Have you ever been in a cave?”

“In a
cave
! Of course not!”

“I thought not. I tried last week—just to see—but I got out in a hurry. I went in until the mouth of the cave was just visible as a blur of light, with black everywhere else. I never thought a person my weight could run that fast.”

Theremon’s lip curled. “Well, if it comes to that, I guess I wouldn’t have run if I had been there.”

The psychologist studied the young man with an annoyed frown.

“My, don’t you talk big! I dare you to draw the curtain.”

Theremon looked his surprise and said, “What for? If we had four or five suns out there, we might want to cut the light down a bit for comfort, but now we haven’t enough light as it is.”

“That’s the point. Just draw the curtain; then come here and sit down.”

“All right.” Theremon reached for the tasseled string and jerked. The red curtain slid across the wide window, the brass rings hissing their way along the crossbar, and a dusk-red shadow clamped down on the room.

* * * *

Theremon’s footsteps sounded hollowly in the silence as he made his way to the table, and then they stopped halfway. “I can’t see you, sir,” he whispered.

“Feel your way,” ordered Sheerin in a strained voice.

“But I can’t see you, sir.” The newsman was breathing harshly. “I can’t see anything.”

“What did you expect?” came the grim reply. “Come here and sit down!”

The footsteps sounded again, waveringly, approaching slowly. There was the sound of someone fumbling with a chair. Theremon’s voice came thinly, “Here I am. I feel…
ulp
…all right.”

“You like it, do you?”

“N—no. It’s pretty awful. The walls seem to be—” He paused. “They seem to be closing in on me. I keep wanting to push them away. But I’m not going
mad
! In fact, the feeling isn’t as bad as it was.”

“All right. Draw the curtain back again.”

There were cautious footsteps through the dark, the rustle of Theremon’s body against the curtain as he felt for the tassel, and then the triumphant
roo-osh
of the curtain slithering back. Red light flooded the room, and with a cry of joy Theremon looked up at the sun.

Sheerin wiped the moistness off his forehead with the back of a hand and said shakily, “And that was just a dark room.”

“It can be stood,” said Theremon lightly.

“Yes, a dark room can. But were you at the Jonglor Centennial Exposition two years ago?”

“No, it so happens I never got around to it. Six thousand miles was just a bit too much to travel, even for the exposition.”

“Well, I was there. You remember hearing about the ‘Tunnel of Mystery’ that broke all records in the amusement area—for the first month or so, anyway?”

“Yes. Wasn’t there some fuss about it?”

“Very little. It was hushed up. You see, that Tunnel of Mystery was just a mile-long tunnel—with no lights. You got into a little open car and jolted along through Darkness for fifteen minutes. It was very popular—while it lasted.”

“Popular?”

“Certainly. There’s a fascination in being frightened
when it’s part of a game.
A baby is born with three instinctive fears: of loud noises, of falling, and of the absence of light. That’s why it’s considered so funny to jump at someone and shout ‘Boo!’ That’s why it’s such fun to ride a roller coaster. And that’s why that Tunnel of Mystery started cleaning up. People came out of that Darkness shaking, breathless, half dead with fear, but they kept on paying to get in.”

“Wait a while, I remember now. Some people came out dead, didn’t they? There were rumors of that after it shut down.”

The psychologist snorted. “Bah! Two or three died. That was nothing! They paid off the families of the dead ones and argued the Jonglor City Council into forgetting it. After all, they said, if people with weak hearts want to go through the tunnel, it was at their own risk—and besides, it wouldn’t happen again. So they put a doctor in the front office and had every customer go through a physical examination before getting into the car. That actually
boosted
ticket sales.”

“Well, then?”

“But you see, there was something else. People sometimes came out in perfect order, except that they refused to go into buildings—any buildings; including palaces, mansions, apartment houses, tenements, cottages, huts, shacks, lean-tos, and tents.”

Theremon looked shocked. “You mean they refused to come in out of the open? Where’d they sleep?”

“In the open.”

“They should have
forced
them inside.”

“Oh, they did, they did. Whereupon these people went into violent hysterics and did their best to bat their brains out against the nearest wall. Once you got them inside, you couldn’t keep them there without a strait jacket or a heavy dose of tranquilizer.”

“They must have been crazy.”

“Which is exactly what they were. One person out of every ten who went into that tunnel came out that way. They called in the psychologists, and we did the only thing possible. We closed down the exhibit.” He spread his hands.
