A Large Anthology of Science Fiction

  The first man nudged him. “Wake up,” he said. “Here’s a astronomical picture about the stars. Wake up. It’ll be good. ‘The Burning of Rome’s’ next.”

  “I ain’t asleep,” Tubby whispered back. “I’m thinking.”

  The wonders of celestial space were unfolding before Tubby’s eyes. But he hardly saw them. He was thinking of what Jake had said—those tremendous figures Jake had reeled off to him. What was it he had said? One hundred and

  eighty-six thousand miles in a second. There were sixty seconds in a minute, and sixty minutes in an hour! That would be—

  “ ’Taint so,” he muttered to himself doggedly.

  He felt a light touch on his arm and looked up to see a little man standing beside him in the aisle. In the dim light Tubby could not see the little man very well; but he could see that he did not know him.

  The little man bent down toward Tubby’s ear.

  I want to talk to you,” he whispered.

  “What about?” said Tubby.

  The little man shook his head. “I can’t talk in here. Come outside for a moment.”

  Tubby hesitated.

  “It’s very important,” the little man added. “You must come—just for a moment. I’ve wanted to see you for a very long time.”

  Tubby clambered to his feet; his two friends, absorbed in the picture before them, did not notice him leave. In silence he followed the stranger back up the aisle to the lighted theater lobby.

  “I’ve wanted to see you for along time,” the little man repeated. Tubby could see now he was a very little man, with a thin, frail body and a very big head set upon a long spindly neck. His hair was snow-white and long about his ears. His yellow face was seamed with lines, but most of it was hidden by flowing side-whiskers and by a pair of huge iron-rimmed spectacles. He wore a long black frock coat that hung from his thin shoulders like a shroud.

  “I’m a professor,” said the stranger. He held out a shriveled, taloned hand. “A Professor of Light,” he added impressively.

  “Oh,” said Tubby.

  “My name is Qbadiah Oats.”

  Tubby shook hands. “Mine’s Tubby,” he said. “Pleased to meet you.”

  The professor put on his high hat, which made him nearly as tall as Tubby.

  “I want to consult you on a matter of very great importance to both of us,” he said slowly.

  Tubby waited.

  “About light,” the professor added. He linked his arm in Tubby’s confidentially. “I need your help. They tell me you’re the smartest man in town. I wanted to find you. With a brain like yours and mine—”

  “Yes,” said Tubby breathlessly, when the professor paused.

  “My laboratory’s right across the street,” said the little man. “I’ll show you.” Tubby followed the professor out of the theater, through a little doorway across the street and up several flights of rickety stairs into a room on the top floor of the house.

  “This is where I work,” said the professor. “Sit down.”

  It was a large room with endless row of bottles upon tiers of shelves lining its walls. Several long tables stood about, and Tubby saw they were crowded with curious apparatus—little tubes in racks, microscopes, triangular pieces of glass with candles behind them, and several contrivances of wheels and weights that looked like clock works. In the exact center of the room was one larger apparatus of a sort Tubby had never seen before; it seemed very complicated and he stared at it with awe. He could make nothing out of it except that part of it was a huge telescope, extending up through the skylight of the room. He glanced upward, and there, through a narrow, open slit in the glass, he could see the stars shining.

  “That’s a Light Machine,” said the professor, following his glance. “There’s only one in the world, and there it is.”

  “Yes,” said Tubby.

  “It’s the most wonderful machine that was ever built,” the professor went on softly. “I built it; and now you are going to help me make money out of it.”

  “Yes,” said Tubby. “How?”

  “That’s what you are going to tell me. Don’t you see? I am a man of science—you are a business man. That’s the difference between us.”

  “Yes,” said Tubby.

  “First I’ll have to explain. You have a head for figures, of course?”

  “No—yes,” said Tubby. “Of course.”

  “But you don’t know much about light?”

  “Yes—no,” said Tubby.

  “Naturally. How could you. Nobody does—but me. And I know all about it—all.” He emphasized the last word impressively. “And now I’m going to tell it to you.”

  “Thank you very much,” said Tubby, and waited.

  “All my life,” began the professor—he spoke softly; his eyes, fixed on Tubby seemed staring at dim, distant spaces—”all my life—since I was a little boy—I have been studying the properties of light. It is a very wonderful thing—you realize that, do you not—the most wonderful thing in the whole of science?”

  “Oh, yes,” said Tubby.

  The professor drew in a deep breath, like a long sigh reversed. “Light,” he began again, “is a vibratory wave in the Ether. You know what the Ether is?”

  “No,” said Tubby.

  “It is like air. But you cannot breathe it. It exists everywhere—even in the outermost realms of Space. Now do you understand?”

  “Yes,” said Tubby.

  “Light is vibration of the Ether,” the professor went on in his droning voice. “Its vibrations travel through the Ether at the rate of one hundred and eighty-six thousand three hundred and twenty-four miles a second.”

  “I know that,” said Tubby.

  “You are learned man,” the professor said admiringly. “You have a wonderful mind. I knew you had—they said so.”

  “Yes,” said Tubby. “Go on.”

  The professor jerked his little body upright in his chair suddenly, so suddenly that Tubby started violently with fright.

  “How long is a second?” the professor asked aggressively.

  “Why—tick-tick. That’s it,” said Tubby.

  The professor relaxed in his chair. “You are a clever man. You will have your little joke.

  “But we must be serious. I will tell you how long a second is. It is exactly one-thirty-one millionth, five hundred and fifty-eight thousandth, one hundred and forty-ninth part of a year.”

  “Oh,” said Tubby.

  “Do you know what a year is?”

  “Three hundred and sixty-five days,” said Tubby promptly.

  The professor smiled again. “A year is the time it takes the Earth to revolve once around the Sun. Thus you see there are 31,558,149 seconds in a year—which is a little more than 365% days.”

  “Yes,” said Tubby. “I see.”

  “Now to find out how far light travels in a year we simply take its speed per second and multiply it by sixty. That is its speed per minute. Multiply that by sixty gives it speed per hour and so on up to a day or a year. Do you understand?”

  “Yes,” said Tubby. “How—how far does it go in a year?”

  The professor raised his hand.

  “That is a very simple problem—only mental arithmetic for me. Wait. Let us go further.”

  “Yes,” said Tubby. “Go on.”

  “The distance Light travels in one year is called a Light-year. Now, some of the stars are so far away that it takes light many centuries to come from them, traveling at that speed I have just mentioned. Thus we measure their distance from us as so many hundred Light-years. Do you see?”

  “Yes,” said Tubby. “How—‘how many miles away from us is the farthest star—the very farthest?”

  The professor leaped to his feet. “Ah, I was expecting you to ask that.” His face was beaming. “You are a clever man. But I’m ready for you. I figured it all out this afternoon and wrote it down. I’ll show you.”

  He led Tubby to a corner of the room. Tubby saw a perfectly enormous
roll of narrow paper tape, like the tape that comes from a stock ticker, or is rolled up around baby ribbon. Only this roll was bigger than he was. It was hung vertically on a spindle, which had a handle to rotate it so that the tape could be unwound and wound again easily. A few feet away there was a similar spindle, but empty.

  “I wrote it down for you,” the professor repeated—”the distance in miles of the furthest star from the Earth. I wrote it down—on this.”

  He took the loose end of the tape and reeling off a few feet hooked the end onto the empty spindle.

  “Watch closely,” he said. “I’m going to show you the number.”

  He started to wind up the tape on the empty spindle. Tubby stood close beside the strip of tape stretching the space between the two spindles; it passed directly under his face.

  “Watch closely,” said the professor again. “There comes the first of it.”

  Tubby saw a row of little digits start on the tape. The first three were 154. Then after the comma began a string of ciphers; after each three ciphers was another comma.

  The moving tape carried this endless row of little ciphers swiftly under Tubby’s nose. He stared at them fascinated. Faster and faster they flew by as the roll of tape wound up on the spindle the professor was turning. For half an hour he turned briskly. Then the row of ciphers stopped just as the other end of the tape fluttered off the unwinding spindle.

  The professor leaned against the wall, breathing hard.

  “That—was—the—number,” he gasped.

  Tubby blinked. “What—what number was it?” he-asked finally.

  The professor recovered his breath and sat down again in his chair wearily.

  “It was one hundred and fifty-four zintillions,” he answered. “The largest number that has ever been written down. I wrote it down this afternoon.”

  “Yes,” said Tubby. “It was a big number.”

  The professor pulled at his side-whiskers thoughtfully. “We must get on,” he said. “Now you understand how far the stars are away. And how fast light travels. That brings us to my Light Machine.”

  Tubby sat up with interest. “To the Light Machine. Yes, go on.”

  “As you can see,” the professor continued. “I know all about Light—I am its master. No one in the world knows as much about Light as I do. And only one man in the world thinks he does.” The professor’s eyes gleamed vindictively. “Ah, how I hate him, that man!”

  “Who?” Tubby asked with interest. “What is his name?”

  “His name is Einstein,” answered the professor. “I hate him—I loathe him—I despise him.”

  “Oh,” said Tubby. “I’m sorry.”

  “But he cannot harm me. I’m too clever for him. And you will help me. We still have time—he cannot prove anything yet”

  “No—yes,” said Tubby.

  The professor stood up. “Let us get on with my invention. Then you’ll see what a wonderful man I am. I will be brief.” Tubby joined him beside the telescope in the center of the room.

  “What you must understand first,” said the professor, “is my theory of Light.” Tubby waited.

  “No light is ever destroyed,” the professor continued. “It passes beyond our vision, that is all. But it always exists somewhere, in the outer realms of Space.”

  “That’s where it goes when it goes out,” Tubby put in. “Ain’t I right?”

  “Yes,” said the professor. “That’s where it goes—out into the realms of Space.

  “Now what you must understand is that light can be reflected, refracted, polarized, but never destroyed. He pointed to his instruments on one of the tables. “I can do all those things to it—and a thousand more—but I cannot destroy it.”

  “Right,” said Tubby. “But if you put it out you can’t never get it back, can you now?”

  The professor beamed on him genially. “Your brain works too keenly,” he said. “You anticipate me. No, I cannot get it back. But it comes back. That’s just the point—it comes back. That’s what nobody in the world knows except me—me and you.

  “The sun,” he went on, “gives us most of our light—it gets here to the earth from the sun in a few minutes. The moon gives us reflected sunlight. It is the same light, only it comes to us from the sun by way of the moon. It takes a little longer that way.”

  “How much?” Tubby asked.

  “Not much—just a few seconds—the moon is not far away. Now all this light that strikes the earth is reflected back into space. In a hundred years—less or more according to the distance—it strikes the different stars. There it mingles with other light. And then, mark me well, and then”—the professor paused impressively—“then in another hundred years it comes back to us again—the same light—mixed with other light of course—but some of the same light we had two hundred years before. Do you understand?”

  “No—yes,” said Tubby.

  “That,” said the professor, “is the Oats Theory of the Rationality of Light. I call it that because it is rational—it is in accordance with all known physical laws.

  “Some others I could name”—the professor’s voice shook with suppressed passon; his eyes gleamed again wickedly—“some others are not so scrupulous. Their theories do not coincide with recognized physical laws—they transgress them all. Mere astronomical outcasts—mathematical lepers—scientific pariahs—”

  “Oh—you mean that other guy?” said Tubby.

  The professor calmed himself with an effort. He pulled a huge black silk handkerchief from his pocket and mopped his dripping forehead.

  “We won’t talk of him,” he said after a moment.

  “No, we better leave him out of it,” Tubby agreed. “Ain’t I right?”

  The professor nodded. “Now we come to my great discovery. I’ll tell you about that now.

  “When this sunlight is reflected from the moon to us, it brings with it an image of ithe moon, which was not in the light when it left the sun. Do you understand?”

  “No—yes,” said Tubby.

  “That’s why we can see the moon—the light brings us the image. All light carries an image of something—that’s why we can see things.

  “Now when light leaves die earth and goes out into space it takes with it an image of the earth and everything that is happening on the earth.”

  “Right,” said Tubby. “Go on.”

  “Now some of this light may have to travel a hundred years before it reaches a star. When it does it mixes with other light and is reflected back in another hundred years to us. But—mark you this—but it still carries the image of the earth and what happened on the earth when it was here.”

  “But you don’t see that,” said Tubby. “We see the star. Ain’t I right?”

  “Yes,” said the professor. “Of course you’re right. And the reason we see the star is because that image is the last one the light got. That is predominate. All the others are there—but they are hidden away beneath the star image.”

  “Oh,” said Tubby.

  “Nobody ever knew they were there, and so of course nobody ever tried to get them out. But I knew they were there—that’s the Oats Theory of the Rationality of Light. And I have got them out!” His voice rose in triumph. “That’s the Light Machine—the greatest invention in the history of the world!”

  “Oh, the Light Machine,” said Tubby, when the professor paused.

  “The Oats Light Machine—here it is—the only one in the world. I’ll show you at once.”

  He switched off the lights. The room was quite dark except for a little beam of white light that seemed to thread its way through the intricate system of mirrors and prisms of the Light Machine. Tubby could not see where this light came from or where it went to. But he saw distinctly that it turned several corners and was alternately broad and narrow. It was white throughout most of its course; but in one short span it was a dark, angry red, and in another a deep, beautiful purple.

  “The Light Machine,” the Professor began; his
fingers caressed one of its little reflectors lovingly, “is able to extract from light all the images it holds, no matter how long they have been there.”

  “That’s wonderful, ain’t it?” said Tubby with admiration.

  “Yes. Let me show you. Here is the telescope. I train it on a star—a star, mark you, that is not a sun, but that shines by reflected light. This beam of starlight, contains moonlight, earthlight, sunlight (our sunlight, you know)—and the light from millions of other suns. The starlight comes out from here”—he touched the lower end of the telescope.

  “Now you see this ray of my own created light passes directly in front of where the starlight comes out—that’s where they mix.”

  Tubby saw the little beam of white light crossed at right angles to the telescope eyepiece and passed very close to it.

  “This light of my own is created by burning zonogen—a gas I discovered myself.

  “From this point, where the starlight joins it, my ray goes to the spectroscope”—he touched another portion of the Light Machine—”and it is polarized here. These”—he indicated a long row of tiny black compartments; Tubby could see the beam of light entering at one end and emerging at the other—“these are my image extractors. Each takes from the light some of its images—leaving finally only the earthlight and the images that belong to it.

  “There are many other processes—some day you will understand them all. But for now—let me show you the result.

  “The pure earthlight passes last of all into my projector. See it here?” He laid his hand on what looked to Tubby something like a magic lantern.

  “My operating power is electricity.” He turned a switch. Tubby first heard a low hum and then a whirring, clicking sound.

  “This projector magnifies the image—throws it up on a screen.” He pointed to the wall; Tubby saw a small square of canvas hung on the wall.

  “Now then,” the professor continued, his voice trembling with emotion, “that star my telescope is pointing at is now exactly nine hundred and twenty-seven and one half Light-years away. That means that eighteen hundred and fifty-five years ago to-night the light we are getting back now from that star left the earth. Do you know what was happening eighteen hundred and fifty-five years ago to-night.”
