The World Turned Upside Down

by Eric Flint

  Tark took one last look at the female bending over the male. He saw her raise her head, and saw the tears in her eyes, and heard the sobs that shook her. Then, in a rising, inchoate series of bewildering emotions, he turned his eyes away, and hurriedly flapped after Vascar. And all that day they pursued Blacky. They circled him, they cornered him; and Vascar tried to speak to him in friendly tones, all to no avail. It only cawed, and darted away, and spoke volumes of disappointingly incomprehensible words.

  When dark came, Vascar alighted in a tree beside the strangely quiet Tark.

  "I suppose it's no use," she said sadly. "Either it is terribly afraid of us, or it is not as intelligent as we supposed it was, or else it has become mentally deranged in these last years of loneliness. I guess we might as well leave now, Tark; let the poor creature have its planet to itself. Shall we stop by and see if we can help the female beast whose mate we shot?"

  Tark slowly looked at her, his red eyes luminous in the gathering dusk. "No," he said briefly. "Let us go, Vascar."

  The spaceship of the creatures from Alcon left the dead planet Earth. It darted out into space. Tark sat at the controls. The ship went faster and faster. And still faster. Fled at ever-increasing speed beyond the Solar System and into the wastes of interstellar space. And still farther, until the star that gave heat to Earth was not even visible.

  Yet even this terrible velocity was not enough for Tark. Vascar looked at him strangely.

  "We're not in that much of a hurry to get home, are we, Tark?"

  "No," Tark said in a low, terrible voice; but still he urged the ship to greater and greater speed, though he knew it was useless. He could run away from the thing that had happened on the planet Earth; but he could never, never outrun his mind, though he passionately wished he could.

  Answer

  by Fredric Brown

  Preface by David Drake

  Fredric Brown's fiction has many virtues. The one that most impressed me when I was first trying to write was that he was the master of the short-short story, the vignette. It is remarkably difficult to tell a real story in 300-500 words. Others have done it—Arthur C. Clarke has done it very successfully—but no one I can think of did it more often and more consistently well than Brown.

  This is an example. It looks as though it should be easy to duplicate it.

  But you just try. Heaven knows, I have . . . and I failed every time.

  Dwar Ev ceremoniously soldered the final connection with gold. The eyes of a dozen television cameras watched him and the sub-ether bore through the universe a dozen pictures of what he was doing.

  He straightened and nodded to Dwar Reyn, then moved to a position beside the switch that would complete the contact when he threw it. The switch that would connect, all at once, all of the monster computing machines of all the populated planets in the universe—ninety-six billion planets—into the supercircuit that would connect them all into one supercalculator, one cybernetics machine that would combine all the knowledge of all the galaxies.

  Dwar Reyn spoke briefly to the watching and listening trillions. Then after a moment's silence he said, "Now, Dwar Ev."

  Dwar Ev threw the switch. There was a mighty hum, the surge of power from ninety-six billion planets. Lights flashed and quieted along the miles-long panel.

  Dwar Ev stepped back and drew a deep breath. "The honor of asking the first question is yours, Dwar Reyn."

  "Thank you," said Dwar Reyn. "It shall be a question which no single cybernetics machine has been able to answer."

  He turned to face the machine. "Is there a God?"

  The mighty voice answered without hesitation, without the clicking of a single relay.

  "Yes, now there is a God."

  Sudden fear flashed on the face of Dwar Ev. He leaped to grab the switch.

  A bolt of lightning from the cloudless sky struck him down and fused the switch shut.

  Afterword by Jim Baen

  I read "Answer" some years after I'd read "The Last Question." My first thought was, "It's the same story!"

  But it wasn't the same story. It wasn't anything like the same story. It just happened to have the same plot.

  That realization made me much less concerned by "originality," because I began to see that nothing was really original, and I became much more concerned about story values. Over the years I've built three SF lines on that principle.

  The Last Question

  by Isaac Asimov

  Preface by David Drake

  The term "pulp" tends to be used as a synonym for any magazine that isn't printed on slick (coated) paper, but it has a more technical meaning also: a magazine measuring seven inches by ten inches, printed on coarse (pulp) paper. The pulps were replaced by the digests (magazines five and a half inches by seven and a half inches, generally but not necessarily on a slightly better grade of paper). In some cases a preexisting title switched to the smaller format (Astounding, Future, etc); in other cases, newly founded digest magazines shot to immediate prominence in the field (Galaxy, Fantasy and Science Fiction).

  The shift in size would be of interest only to collectors if it weren't for the fact the contents also changed to stories of much higher literary quality. I have no idea why that should be—perhaps it was merely coincidence. (There had been no comparable change when magazines shrank from the still-larger bedsheet size to pulp size.)

  Isaac Asimov was a prominent regular in the first SF digest, Astounding, but although he published most of his best-known work in digest magazines, he remained a regular right up to the end in the last of the SF pulps, Science Fiction Quarterly.

  This story appeared in the November 1956 issue of SFQ, about a year before the publisher finally closed down the magazine in favor of its digest titles. "The Last Question" is in every sense a pulp story.

  But you'll note that I never said pulp fiction was stupid.

  The last question was asked for the first time, half in jest, on May 21, 2061, at a time when humanity first stepped into the light. The question came about as a result of a five-dollar bet over highballs, and it happened this way:

  Alexander Adell and Bertram Lupov were two of the faithful attendants of Multivac. As well as any human beings could, they knew what lay behind the cold, clicking, flashing face—miles and miles of face—of that giant computer. They had at least a vague notion of the general plan of relays and circuits that had long since grown past the point where any single human could possibly have a firm grasp of the whole.

  Multivac was self-adjusting and self-correcting. It had to be, for nothing human could adjust and correct it quickly enough or even adequately enough. So Adell and Lupov attended the monstrous giant only lightly and superficially, yet as well as any men could. They fed it data, adjusted questions to its needs and translated the answers that were issued. Certainly they, and all others like them, were fully entitled to share in the glory that was Multivac's.

  For decades, Multivac had helped design the ships and plot the trajectories that enabled man to reach the Moon, Mars, and Venus, but past that, Earth's poor resources could not support the ships. Too much energy was needed for the long trips. Earth exploited its coal and uranium with increasing efficiency, but there was only so much of both.

  But slowly Multivac learned enough to answer deeper questions more fundamentally, and on May 14, 2061, what had been theory, became fact.

  The energy of the sun was stored, converted, and utilized directly on a planet-wide scale. All Earth turned off its burning coal, its fissioning uranium, and flipped the switch that connected all of it to a small station, one mile in diameter, circling the Earth at half the distance of the Moon. All Earth ran by invisible beams of sunpower.

  Seven days had not sufficed to dim the glory of it and Adell and Lupov finally managed to escape from the public function, and to meet in quiet where no one would think of looking for them, in the deserted underground chambers, where portions of the mighty buried body of Multivac showed. Una
ttended, idling, sorting data with contented lazy clickings, Multivac, too, had earned its vacation and the boys appreciated that. They had no intention, originally, of disturbing it.

  They had brought a bottle with them, and their only concern at the moment was to relax in the company of each other and the bottle.

  "It's amazing when you think of it," said Adell. His broad face had lines of weariness in it, and he stirred his drink slowly with a glass rod, watching the cubes of ice slur clumsily about. "All the energy we can possibly ever use for free. Enough energy, if we wanted to draw on it, to melt all Earth into a big drop of impure liquid iron, and still never miss the energy so used. All the energy we could ever use, forever and forever and forever."

  Lupov cocked his head sideways. He had a trick of doing that when he wanted to be contrary, and he wanted to be contrary now, partly because he had had to carry the ice and glassware. "Not forever," he said.

  "Oh, hell, just about forever. Till the sun runs down, Bert."

  "That's not forever."

  "All right, then. Billions and billions of years. Twenty billion, maybe. Are you satisfied?"

  Lupov put his fingers through his thinning hair as though to reassure himself that some was still left and sipped gently at his own drink. "Twenty billion years isn't forever."

  "Well, it will last our time, won't it?"

  "So would the coal and uranium."

  "All right, but now we can hook up each individual spaceship to the Solar Station, and it can go to Pluto and back a million times without ever worrying about fuel. You can't do that on coal and uranium. Ask Multivac, if you don't believe me."

  "I don't have to ask Multivac. I know that."

  "Then stop running down what Multivac's done for us," said Adell, blazing up, "It did all right."

  "Who says it didn't? What I say is that a sun won't last forever. That's all I'm saying. We're safe for twenty billion years, but then what?" Lupov pointed a slightly shaky finger at the other. "And don't say we'll switch to another sun."

  There was silence for a while. Adell put his glass to his lips only occasionally, and Lupov's eyes slowly closed. They rested.

  Then Lupov's eyes snapped open. "You're thinking we'll switch to another sun when ours is done, aren't you?"

  "I'm not thinking."

  "Sure you are. You're weak on logic, that's the trouble with you. You're like the guy in the story who was caught in a sudden shower and who ran to a grove of trees and got under one. He wasn't worried, you see, because he figured when one tree got wet through, he would just get under another one."

  "I get it," said Adell. "Don't shout. When the sun is done, the other stars will be gone, too."

  "Darn right they will," muttered Lupov. "It all had a beginning in the original cosmic explosion, whatever that was, and it'll all have an end when all the stars run down. Some run down faster than others. Hell, the giants won't last a hundred million years. The sun will last twenty billion years and maybe the dwarfs will last a hundred billion for all the good they are. But just give us a trillion years and everything will be dark. Entropy has to increase to maximum, that's all."

  "I know all about entropy," said Adell, standing on his dignity.

  "The hell you do."

  "I know as much as you do."

  "Then you know everything's got to run down someday."

  "All right. Who says they won't?"

  "You did, you poor sap. You said we had all the energy we needed, forever. You said 'forever.'"

  It was Adell's turn to be contrary. "Maybe we can build things up again someday," he said.

  "Never."

  "Why not? Someday."

  "Never."

  "Ask Multivac."

  "You ask Multivac. I dare you. Five dollars says it can't be done."

  Adell was just drunk enough to try, just sober enough to be able to phrase the necessary symbols and operations into a question which, in words, might have corresponded to this: Will mankind one day without the net expenditure of energy be able to restore the sun to its full youthfulness even after it had died of old age?

  Or maybe it could be put more simply like this: How can the net amount of entropy of the universe be massively decreased?

  Multivac fell dead and silent. The slow flashing of lights ceased, the distant sounds of clicking relays ended.

  Then, just as the frightened technicians felt they could hold their breath no longer, there was a sudden springing to life of the teletype attached to that portion of Multivac. Five words were printed: INSUFFICIENT DATA FOR MEANINGFUL ANSWER.

  "No bet," whispered Lupov. They left hurriedly.

  By next morning, the two, plagued with throbbing head and cottony mouth, had forgotten the incident.

  Jerrodd, Jerrodine, and Jerrodette I and II watched the starry picture in the visiplate change as the passage through hyperspace was completed in its non-time lapse. At once, the even powdering of stars gave way to the predominance of a single bright marble-disk, centered.

  "That's X-23," said Jerrodd confidently. His thin hands clamped tightly behind his back and the knuckles whitened.

  The little Jerrodettes, both girls, had experienced the hyperspace passage for the first time in their lives and were self-conscious over the momentary sensation of inside-outness. They buried their giggles and chased one another wildly about their mother, screaming, "We've reached X-23—we've reached X-23—we've—"

  "Quiet, children," said Jerrodine sharply. "Are you sure, Jerrodd?"

  "What is there to be but sure?" asked Jerrodd, glancing up at the bulge of featureless metal just under the ceiling. It ran the length of the room, disappearing through the wall at either end. It was as long as the ship.

  Jerrodd scarcely knew a thing about the thick rod of metal except that it was called a Microvac, that one asked it questions if one wished; that if one did not it still had its task of guiding the ship to a preordered destination; of feeding on energies from the various Sub-galactic Power Stations; of computing the equations for the hyperspacial jumps.

  Jerrodd and his family had only to wait and live in the comfortable residence quarters of the ship.

  Someone had once told Jerrodd that the "ac" at the end of "Microvac" stood for "analog computer" in ancient English, but he was on the edge of forgetting even that.

  Jerrodine's eyes were moist as she watched the visiplate. "I can't help it. I feel funny about leaving Earth."

  "Why, for Pete's sake?" demanded Jerrodd. "We had nothing there. We'll have everything on X-23. You won't be alone. You won't be a pioneer. There are over a million people on the planet already. Good Lord, our great-grandchildren will be looking for new worlds because X-23 will be overcrowded." Then, after a reflective pause, "I tell you, it's a lucky thing the computers worked out interstellar travel the way the race is growing."

  "I know, I know," said Jerrodine miserably.

  Jerrodette I said promptly, "Our Microvac is the best Microvac in the world."

  "I think so, too," said Jerrodd, tousling her hair.

  It was a nice feeling to have a Microvac of your own and Jerrodd was glad he was part of his generation and no other. In his father's youth, the only computers had been tremendous machines taking up a hundred square miles of land. There was only one to a planet. Planetary ACs they were called. They had been growing in size steadily for a thousand years and then, all at once, came refinement. In place of transistors, had come molecular valves so that even the largest Planetary AC could be put into a space only half the volume of a spaceship.

  Jerrodd felt uplifted, as he always did when he thought that his own personal Microvac was many times more complicated than the ancient and primitive Multivac that had first tamed the Sun, and almost as complicated as Earth's Planetary AC (the largest) that had first solved the problem of hyperspatial travel and had made trips to the stars possible.

  "So many stars, so many planets," sighed Jerrodine, busy with her own thoughts. "I suppose families will
be going out to new planets forever, the way we are now."

  "Not forever," said Jerrodd, with a smile. "It will all stop someday, but not for billions of years. Many billions. Even the stars run down, you know. Entropy must increase."

  "What's entropy, daddy?" shrilled Jerrodette II.

  "Entropy, little sweet, is just a word which means the amount of running-down of the universe. Everything runs down, you know, like your little walkie-talkie robot, remember?"

  "Can't you just put in a new power-unit, like with my robot?"

  "The stars are the power-units, dear. Once they're gone, there are no more power-units."

  Jerrodette I at once set up a howl. "Don't let them, daddy. Don't let the stars run down."

  "Now look what you've done," whispered Jerrodine, exasperated.

  "How was I to know it would frighten them?" Jerrodd whispered back.

  "Ask the Microvac," wailed Jerrodette I. "Ask him how to turn the stars on again."

  "Go ahead," said Jerrodine. "It will quiet them down." (Jerrodette II was beginning to cry, also.)

  Jerrodd shrugged. "Now, now, honeys. I'll ask Microvac. Don't worry, he'll tell us."

  He asked the Microvac, adding quickly, "Print the answer."

  Jerrodd cupped the strip of thin cellufilm and said cheerfully, "See now, the Microvac says it will take care of everything when the time comes so don't worry."

  Jerrodine said, "And now, children, it's time for bed. We'll be in our new home soon."

  Jerrodd read the words on the cellufilm again before destroying it: INSUFFICIENT DATA FOR MEANINGFUL ANSWER.

  He shrugged and looked at the visiplate. X-23 was just ahead.

  VJ-23X of Lameth stared into the black depths of the three-dimensional, small-scale map of the Galaxy and said, "Are we ridiculous, I wonder, in being so concerned about the matter?"
