By Dewey, G. Gordon [Transcriber's Note: This etext was produced from Orbit volume 1 number 2, 1953. Extensive research did not uncover any evidence that the U.S. was not clever enough to remold the outlines of a were only room. But this is an experimental flight—no more than two can go." about the flight tomorrow." The young spaceman's eyes were puzzled, hurt. "But Ninon, I've told you from him. But he blundered on. "... or very old, no longer the Ninon I know ... oh, all right. But you know all this already. We've had space flight for years, but only rocket-powered, restricting us to our own system. Now we have a new kind of drive. Theoretically we can travel faster than light—how many times faster we don't know yet. I'll start finding out tomorrow, with the first test flight of the ship in which the new drive is installed. If it works, the universe is ours—we can go anywhere." "Will it work?" Ninon could not keep the avid greediness out of her voice. time tomorrow." "What of you—of me—. What does this mean to us—to people?" Again the young spaceman hesitated. "We ... we don't know, yet. We think that time won't have the same meaning to everyone...." "... When you travel faster than light. Is that it?" "Well ... yes. Something like that." "And I'll be—old—or dead, when you get back? If you get back?" But of what use is it to you? I have neither money nor power. I'll be gone from this Earth in an hour. And you'll be gone from it, permanently—at your age—before I get back. I have nothing to lose, and you have nothing to gain." Venomous with triumph, Ninon's voice was harsh even to her ears. "On the contrary, my proud and impetuous young spaceman, I have much to gain, more than you could ever understand. When it was announced that you were Space Research knew that you had not...." "I see. That's why you recorded my visit tonight. But I leave in less than an hour. You'd never be able to tell Commander Pritchard in time to affects the success of the flight." The young spaceman's face was white and stricken as he stared for long where his car waited. "We must hurry," she said breathlessly. "We can get to the spaceship ahead of schedule, before your flight partner arrives, and be gone from Earth before anyone knows what is happening. I'll be with you, in his place." waited until she closed the door behind her, then sped away from the curb and through the streets to the spaceport. Earth at the speed of light, and if we could watch it as it did so, it would still be running but it would never show later time?" The young man said gruffly, "Roughly so, according to theory." "And if the clock went away from Earth faster than the speed of light, wouldn't it run backwards?" The answer was curtly cautious. "It might appear to." "Then if people travel at the speed of light they won't get any older?" Robert flicked a curious glance at her. "If you could watch them from Earth they appear not to. But it's a matter of relativity...." Ninon rushed on. She had studied that book carefully. "And if people travel faster than light, a lot faster, they'll grow younger, won't they?" Robert said, "So that's what's in your mind." He busied himself with his gaze a curious mixture of amusement and pity. Then, "Come on," he said flatly, turning to lead the way to the gleaming space ship which poised, towering like a spire, in the center of the blast-off basin. And added, "I think I shall enjoy this trip, Madame, more than you will." frown again. And after a few years she could make the trip again ... and again.... The space ship stood on fiery tiptoes and leaped from Earth, high into the heavens, and out and away. Past rusted Mars. Past the busy asteroids. Past the sleeping giants, Jupiter and Saturn. Past pale Uranus and Neptune and frigid, shivering Pluto. Past a senseless, flaming comet rushing inward towards its rendezvous with the Sun. And on out of the System into the steely blackness of space where the stars "Barely crawling, astronomically," he said shortly. "About forty-six thousand miles a minute." "Is that as fast as the speed of light?" "Hardly, Madame," he said, with a condescending chuckle. "Then make it go faster!" she screamed. "And faster and faster—hurry! What are we waiting for?" The young spaceman swivelled about in his seat. He looked haggard and all operations are plotted. There is nothing we can galaxy, shooting into her face like blazing pebbles from a giant slingshot. She asked, "How fast are we going now?" speed of light." "Make it go faster!" she cried. "Faster! Faster!" of space. She shuddered, and knew without asking that these were stars dropping behind at a rate greater than light speed. "Now how fast are we going?" she asked. She was sure that her voice was stronger "Nearly twice light speed." "Faster!" she cried. "We must go much faster! I must be young again. Youthful, and gay, and alive and happy.... Tell me, Robert, do you feel now, Robert?" He answered without turning. "Yes. Many times the speed of light." springy vitality of a girl of twenty. And then as she watched through the ingenious ports she saw the stars of the far galaxies beginning to wheel about through space, and she knew that the ship had reached the halfway point and was turning to speed back through space to Earth, uncounted light-years behind them—or before them. And she would still continue to grow younger and younger.... becoming more and more beautiful? Am I not in truth the most desirable she got back to Earth. And that would be soon. She must rest more, and be ready. The light drive cut off, and the great ship slowly decelerated as it found its way back into the galaxy from which it had started. Found its way back into the System which had borne it. Ninon watched through the distance from it, waiting until they could come closer and greet the brave passengers who had voyaged through space from no one knew where. There was shouting and laughing and talking, and much speculation. And another: "No, no! It is not of this system. See how the hull is pitted—it has traveled from afar." to that in the space ship we are building, yet not the same. It is obviously not of our Aerth." And a savant said, "Yes, not of this Aerth. But perhaps it is from a parallel time stream, where there is a system with planets and peoples like us." other. She said, "I wonder, Robin, what it would be like to travel through far space on such a ship as that." He squeezed her hand and said, "We'll find out, Nina. Space travel will come, in our time, they've always said—and there is the proof of it." The girl rested her head against the young man's shoulder. "You'll be one of the first, won't you, Robin? And you'll take me with you?" He slipped an arm around her. "Of course. You know, Nina, our scientists say that if one could travel faster than the speed of light one could live in reverse. So when we get old we'll go out in space, very, very fast, and we'll grow young again, together!" Then a shout went up from the two men who had gone up the ramp into the alive on the ship," they cried. "Only an old, withered, white-haired lady, lying dead ... and alone. She must have fared long and far to have lived so long, to be so old in death. Space travel must be pleasant, indeed. It made her very happy, very, very happy—for there is a smile on her face."
