Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] Changing the world is simple Max Alben pulled the little red switch toward him. It was a good job and Max Alben knew whom he had to thank for it—his This was the first time he had seen it, since he had been taught how to operate it on a dummy model, and now he stared at the great transparent coils and the susurrating energy bubble with much respect. This machine, the pride and the hope of 2089, was something almost outside his powers of comprehension. But Max Alben knew how to run it, and he knew, roughly, what it was supposed to accomplish. He knew also that this was the first backward journey of any great duration and, being scientifically unpredictable, might well be the death of him. If his great-grandfather had not volunteered for the earliest time-travel experiments way back in the nineteen-seventies, back even before the Blight, it would never have been discovered that he and his seed possessed a great deal of immunity to extra-temporal blackout. And if that had not been discovered, the ruling powers of Earth, more than a century later, would never have plucked Max Alben out of an livestock wealth of the Western Hemisphere—thoroughly content with the half-pail of dried apricots he received each and every payday. No, if his great-grandfather had not demonstrated long ago his unique capacity for remaining conscious during time travel, Max Alben would not now be shifting from foot to foot in a physics laboratory, facing the black market kings of the world and awaiting their final instructions with an uncertain and submissive grin. Men like O'Hara, who controlled mushrooms, Levney, the blackberry Alben. alter human history for the better. Very much for the better. Yes." He paused, having evidently stumbled out of his thought sequence. originally planned." The Secretary-General of the United Nations beamed. "Thus preventing the Blight, making it nonexistent, as it were, producing a present-day Alben kept his eyes deferentially in their direction, too, as he had throughout this period of last-minute instruction. He knew who ruled his world—these stolid, well-fed men in clean garments with a minimum of patches, and where patches occurred, at least they were the color of the surrounding cloth. where Alben stood in the entrance of the time machine and handed the Max Alben gulped and nodded violently. He darted to the rear of the being put into operation. But it meant a lot more to Mac Albin than merely saving a world. It meant an adventurous mission with the risk of If his great-grandfather had not volunteered for the earliest time-travel experiments way back in the nineteen-seventies, back even before the Epidemic, it would never have been discovered that he and his seed possessed a great deal of immunity to extra-temporal blackout. And if that had not been discovered, the Albins would not have become physicists upon the passage of the United Nations law that everyone been reluctantly selected by his two co-workers as the one to carry the forbidden banner of dangerous experiment. No, if his great-grandfather had not demonstrated long ago his unique laboriously working out dreary gene problems instead of embarking on the greatest adventure Man had known to date. Even if he didn't come back, he had at last found a socially useful escape from genetic responsibility to humanity in general and his own their way, the conservative way: a worldwide concentration on genetics research coupled with the maximum preservation of existing human lives, Albin turned it around curiously. "How?" "I hope you do," Bob Skeat sighed. "I hope you do know that. A twentieth century poet once wrote something to the effect that the world will end not with a bang, but a whimper. Well, our world is forces that drove the time machine. flick! It was strange, Max Alben reflected, that this time travel business, he had been told. There must be some complicated scientific explanation for it, he decided—and that would make it none of his business. Better was the first man to note that, while the symptoms of this disease were substantially milder than those of its unmutated parent, practically no one was immune to it and its effects on human reproductivity were truly for a long time, it successfully defied all the vaccines and serums attempted against it. Then, when a vaccine was finally perfected, humanity discovered to its dismay that its generative powers had been permanently and fundamentally impaired. Strict eugenic control was instituted by the Security Council of the United Nations so that fertile men and women would not be wasted upon non-fertile mates. Fertility was the most important avenue to social was now so limited in proportion to the great resources available, all physical labor had long been done by robots. The government saw to it that everybody had an ample supply of goods and, in return, asked only that they experiment without any risk to their own lives—every human being was now a much-prized, highly guarded rarity. point, it had been estimated, where a species might be wiped out by a new calamity. Not that another calamity would be needed. Since the end of the Epidemic, the birth rate had been moving further and further behind the death rate. In another century.... That was why a desperate and secret attempt to alter the past was being made. This kind of world was evidently impossible. Max Alben finished the manuscript and sighed. What a wonderful world! Experiment. Carefully, carefully, like an obstetrician supervising surgical robots at an unusually difficult birth, he watched the simplicity, like a textbook composed by a stuffy pedagogue for the use of morons. The problems all began with the Guided Missile Experiment of 1976, he But the nutritive potential of Earth was steadily diminishing in a horrifying geometric progression. Recently, it had been observed, But the Blight was still adjusting to new plants and the food supply kept shrinking. In another century.... That was why the planet's powerful individuals had been persuaded to pool their wealth in a desperate attempt to alter the past. This kind of world was manifestly impossible. Mac Albin finished the document and sighed. What a magnificent world! even the black market kings, had all warned him not to go ahead with his instructions if anything unusual turned up. That was an awful lot of power to disobey: he knew he should return with this new information and let better minds work on it. They with their easy lives, what did they know what existence had been all, lots and lots of food. He'd even be a scientist— everyone The fear left him and, for the first time in his life, Max Alben felt Max Alben pulled the little red switch toward him. reality all around him, Mac Albin felt a bit of shame at what he was doing. He'd promised Bob and Hugo to drop the experiment at any stage if a new factor showed up. He knew he should go back with this new adjustment to their thoroughly blueprinted lives? They, at least, had been ordered to marry women they could live with he'd drawn a female with whom he was completely incompatible in any but a genetic sense. Genetics! He was tired of genetics and the sanctity of human life, tired to the tip of his uncalloused fingers, tired to the recesses of his unused muscles. He was tired of having to undertake a simple adventure like a thief in the night. But in this other world, this other 2089, someone like himself would be a monarch of the black market, a suzerain of chaos, making his own rules, taking his own women. So what if the weaklings, those unfit to carry on the race, went to the wall? His kind wouldn't. He'd formed a pretty good idea of the kind of men who ruled that other they had not grasped the idea that an alternate time track would mean their own place than where he'd come from. It deserved a chance. Yes, that was how he felt: his world was drowsily moribund this alternate was Albin decided that he was experiencing renunciation and felt proud.
