"I know I'm right," Russell pleaded. "My hunches always been right. My hunch got us out of that prison didn't it? Listen--I tell you it's that star to the left--"
"The one to the right," said Johnson.
"We been going away from the right one all the time," said Alvar.
"We got to stay together," said Russell. "Nobody could spend a year out here ... alone...."
"Ah ... in another month or so we'd be lousy company anyway," Alvar said. "Maybe a guy could get to the point where he'd sleep most of the time ... just wake up enough times to give himself another boost with the old life-gun."
"We got to face it," Johnson said finally. "We three don't go on together any more."
"That's it," said Alvar. "There's three suns that look like they might be right seeing as how we all agree the old man was wrong. But we believe there is one we can live by, because we all seem to agree that the old man might have been right about that. If we stick together, the chance is three to one against us. But if each of us makes for one star, one of us has a chance to live. Maybe not in paradise like the old man said, but a place where we can live. And maybe there'll be intelligent life, maybe even a ship, and whoever gets the right star can come and help the other two...."
"No ... God no...." Russell whispered over and over. "None of us can ever make it alone...."
Alvar said, "We each take the star he likes best. I'll go back the other way. Russ, you take the left. And you, Johnson, go to the right."
Johnson started to laugh. Russell was yelling wildly at them, and above his own yelling he could hear Johnson's rising laughter. "Every guy's got a star of his own," Johnson said when he stopped laughing. "And we got ours. A nice red-rimmed sun for each of us to call his very own."
"Okay," Alvar said. "We cut off the gravity rope, and each to his own sun."
Now Russell wasn't saying anything.
"And the old man," Alvar said, "can keep right on going toward what he thought was right. And he'll keep on going. Course he won't be able to give himself another boost with the life-gun, but he'll keep going. Someday he'll get to that red-rimmed star of his. Out here in space, once you're going, you never stop ... and I guess there isn't any other body to pull him off his course. And what will time matter to old Dunbar? Even less than to us, I guess. He's dead and he won't care."
"Ready," Johnson said. "I'll cut off the gravity rope."
"I'm ready," Alvar said. "To go back toward whatever it was I started from."
Russell couldn't say anything. He stared at the endless void which now he would share with no one. Not even crazy old Dunbar.
"All right," Johnson said. "Good-bye."
Russell felt the release, felt the sudden inexplicable isolation and aloneness even before Alvar and Johnson used their life-guns and shot out of sight, Johnson toward the left and Alvar back toward that other red-rimmed sun behind them.
And old Dunbar shooting right on ahead. And all three of them dwindling and dwindling and blinking out like little lights.
Fading, he could hear their voices. "Each to his own star," Johnson said. "On a bee line."
"On a bee line," Alvar said.
Russell used his own life-gun and in a little while he didn't hear Alvar or Johnson's voices, nor could he see them. They were thousands of miles away, and going further all the time.
Russell's head fell forward against the front of his helmet, and he closed his eyes. "Maybe," he thought, "I shouldn't have killed the old man. Maybe one sun's as good as another...."
Then he raised his body and looked out into the year of blackness that waited for him, stretching away to the red-rimmed sun. Even if he were right--he was sure now he'd never make it alone.
The body inside the pressure suit drifted into a low-level orbit around the second planet from the sun of its choice, and drifted there a long time. A strato-cruiser detected it by chance because of the strong concentration of radio-activity that came from it.
They took the body down to one of the small, quiet towns on the edge of one of the many blue lakes where the domed houses were like bright joyful jewels. They got the leathery, well-preserved body from the pressure suit.
"An old man," one of them mused. "A very old man. From one of the lost sectors. I wonder how and why he came so very far from his home?"
"Wrecked a ship out there, probably," one of the others said. "But he managed to get this far. It looks as though a small meteor fragment pierced his body. Here. You see?"
"Yes," another of them said. "But what amazes me is that this old man picked this planet out of all the others. The only one in this entire sector that would sustain life."
"Maybe he was just a very lucky old man. Yes ... a man who attains such an age was usually lucky. Or at least that is what they say about the lost sectors."
"Maybe he knew the way here. Maybe he was here before--sometime."
The other shook his head. "I don't think so. They say some humans from that far sector did land here--but that's probably only a myth. And if they did, it was well over a thousand years ago."
Another said. "He has a fine face, this old man. A noble face. Whoever he is ... wherever he came from, he died bravely and he knew the way, though he never reached this haven of the lost alive."
"Nor is it irony that he reached here dead," said the Lake Chieftain. He had been listening and he stepped forward and raised his arm. "He was old. It is obvious that he fought bravely, that he had great courage, and that he knew the way. He will be given a burial suitable to his stature, and he will rest here among the brave.
"Let the women dance and the music play for this old man. Let the trumpets speak, and the rockets fly up. And let flowers be strewn over the path above which the women will carry him to rest."
THE WORLDS OF IF.
By Stanley G. Weinbaum
I stopped on the way to the Staten Island Airport to call up, and that was a mistake, doubtless, since I had a chance of making it otherwise. But the office was affable. "We'll hold the ship five minutes for you," the clerk said. "That's the best we can do."
So I rushed back to my taxi and we spun off to the third level and sped across the Staten bridge like a comet treading a steel rainbow. I had to be in Moscow by evening, by eight o'clock, in fact, for the opening of bids on the Ural Tunnel. The Government required the personal presence of an agent of each bidder, but the firm should have known better than to send me, Dixon Wells, even though the N. J. Wells Corporation is, so to speak, my father. I have a--well, an undeserved reputation for being late to everything; something always comes up to prevent me from getting anywhere on time. It's never my fault; this time it was a chance encounter with my old physics professor, old Haskel van Manderpootz. I couldn't very well just say hello and good-bye to him; I'd been a favorite of his back in the college days of 2014.
I missed the airliner, of course. I was still on the Staten Bridge when I heard the roar of the catapult and the Soviet rocket Baikal hummed over us like a tracer bullet with a long tail of flame.
We got the contract anyway; the firm wired our man in Beirut and he flew up to Moscow, but it didn't help my reputation. However, I felt a great deal better when I saw the evening papers; the Baikal, flying at the north edge of the eastbound lane to avoid a storm, had locked wings with a British fruitship and all but a hundred of her five hundred passengers were lost. I had almost become "the late Mr. Wells" in a grimmer sense.
I'd made an engagement for the following week with old van Manderpootz. It seems he'd transferred to N.Y.U. as head of the department of Newer Physics--that is, of Relativity. He deserved it; the old chap was a genius if ever there was one, and even now, eight years out of college, I remember more from his course than from half a dozen calculus, steam and gas, mechanics, and other hazards on the path to an engineer's education. So on Tuesday night I dropped in an hour or so late, to tell the truth, since I'd forgotten about the engagement until mid-evening.
He was reading in a room as disorderly as ever. "Humph!" he grunted. "Time changes everything but habit, I see. You were a good student, Dick, but I seem to recall that you always arrived in class toward the middle of the lecture."
"I had a course in East Hall just before," I explained. "I couldn't seem to make it in time."
"Well, it's time you learned to be on time," he growled. Then his eyes twinkled. "Time!" he ejaculated. "The most fascinating word in the language. Here we've used it five times (there goes the sixth time--and the seventh!) in the first minute of conversation; each of us understands the other, yet science is just beginning to learn its meaning. Science? I mean that I am beginning to learn."
I sat down. "You and science are synonymous," I grinned. "Aren't you one of the world's outstanding physicists?"
"One of them!" he snorted. "One of them, eh! And who are the others?"
"Oh, Corveille and Hastings and Shrimski--"
"Bah! Would you mention them in the same breath with the name of van Manderpootz? A pack of jackals, eating the crumbs of ideas that drop from my feast of thoughts! Had you gone back into the last century, now--had you mentioned Einstein and de Sitter--there, perhaps, are names worthy to rank with (or just below) van Manderpootz!"
I grinned again in amusement. "Einstein was considered pretty good, wasn't he?" I remarked. "After all, he was the first to tie time and space to the laboratory. Before him they were just philosophical concepts."
"He didn't!" rasped the professor. "Perhaps, in a dim, primitive fashion, he showed the way, but I--I, van Manderpootz--am the first to seize time, drag it into my laboratory, and perform an experiment on it."
"Indeed? And what sort of experiment?"
"What experiment, other than simple measurement, is it possible to perform?" he snapped.
"Why--I don't know. To travel in it?"
"Like these time-machines that are so popular in the current magazines? To go into the future or the past?"
"Bah! Many bahs! The future or the past--pfui! It needs no van Manderpootz to see the fallacy in that. Einstein showed us that much."
"How? It's conceivable, isn't it?"
"Conceivable? And you, Dixon Wells, studied under van Manderpootz!" He grew red with emotion, then grimly calm. "Listen to me. You know how time varies with the speed of a system--Einstein's relativity."
"Very well. Now suppose then that the great engineer Dixon Wells invents a machine capable of traveling very fast, enormously fast, nine-tenths as fast as light. Do you follow? Good. You then fuel this miracle ship for a little jaunt of a half million miles, which, since mass (and with it inertia) increases according to the Einstein formula with increasing speed, takes all the fuel in the world. But you solve that. You use atomic energy. Then, since at nine-tenths light-speed, your ship weighs about as much as the sun, you disintegrate North America to give you sufficient motive power. You start off at that speed, a hundred and sixty-eight thousand miles per second, and you travel for two hundred and four thousand miles. The acceleration has now crushed you to death, but you have penetrated the future." He paused, grinning sardonically. "Haven't you?"
"And how far?"
"Use your Einstein formula!" he screeched. "How far? I'll tell you. One second!" He grinned triumphantly. "That's how possible it is to travel into the future. And as for the past--in the first place, you'd have to exceed light-speed, which immediately entails the use of more than an infinite number of horsepowers. We'll assume that the great engineer Dixon Wells solves that little problem too, even though the energy out-put of the whole universe is not an infinite number of horsepowers. Then he applies this more than infinite power to travel at two hundred and four thousand miles per second for ten seconds. He has then penetrated the past. How far?"
Again I hesitated.
"I'll tell you. One second!" He glared at me. "Now all you have to do is to design such a machine, and then van Manderpootz will admit the possibility of traveling into the future--for a limited number of seconds. As for the past, I have just explained that all the energy in the universe is insufficient for that."
"But," I stammered, "you just said that you--"
"I did not say anything about traveling into either future or past, which I have just demonstrated to you to be impossible--a practical impossibility in the one case and an absolute one in the other."
"Then how do you travel in time?"
"Not even van Manderpootz can perform the impossible," said the professor, now faintly jovial. He tapped a thick pad of typewriter paper on the table beside him. "See, Dick, this is the world, the universe." He swept a finger down it. "It is long in time, and"--sweeping his hand across it--"it is broad in space, but"--now jabbing his finger against its center--"it is very thin in the fourth dimension. Van Manderpootz takes always the shortest, the most logical course. I do not travel along time, into past or future. No. Me, I travel across time, sideways!"
I gulped. "Sideways into time! What's there?"
"What would naturally be there?" he snorted. "Ahead is the future; behind is the past. Those are real, the worlds of past and future. What worlds are neither past nor future, but contemporary and yet--extemporal--existing, as it were, in time parallel to our time?"
I shook my head.
"Idiot!" he snapped. "The conditional worlds, of course! The worlds of 'if.' Ahead are the worlds to be; behind are the worlds that were; to either side are the worlds that might have been--the worlds of 'if!'"
"Eh?" I was puzzled. "Do you mean that you can see what will happen if I do such and such?"
"No!" he snorted. "My machine does not reveal the past nor predict the future. It will show, as I told you, the conditional worlds. You might express it, by 'if I had done such and such, so and so would have happened.' The worlds of the subjunctive mode."
"Now how the devil does it do that?"
"Simple, for van Manderpootz! I use polarized light, polarized not in the horizontal or vertical planes, but in the direction of the fourth dimension--an easy matter. One uses Iceland spar under colossal pressures, that is all. And since the worlds are very thin in the direction of the fourth dimension, the thickness of a single light wave, though it be but millionths of an inch, is sufficient. A considerable improvement over time-traveling in past or future, with its impossible velocities and ridiculous distances!"
"But--are those--worlds of 'if'--real?"
"Real? What is real? They are real, perhaps, in the sense that two is a real number as opposed to [sq]-2, which is imaginary. They are the worlds that would have been if-- Do you see?"
I nodded. "Dimly. You could see, for instance, what New York would have been like if England had won the Revolution instead of the Colonies."
"That's the principle, true enough, but you couldn't see that on the machine. Part of it, you see, is a Horsten psychomat (stolen from one of my ideas, by the way) and you, the user, become part of the device. Your own mind is necessary to furnish the background. For instance, if George Washington could have used the mechanism after the signing of peace, he could have seen what you suggest. We can't. You can't even see what would have happened if I hadn't invented the thing, but I can. Do you understand?"
"Of course. You mean the background has to rest in the past experiences of the user."
"You're growing brilliant," he scoffed. "Yes. The device will show ten hours of what would have happened if--condensed, of course, as in a movie, to half an hour's actual time."
"Say, that sounds interesting!"
"You'd like to see it? Is there anything you'd like to find out? Any choice you'd alter?"
"I'll say--a thousand of 'em. I'd like to know what would have happened if I'd sold out my stocks in 2009 instead of '10. I was a millionaire in my own right then, but I was a little--well, a little late in liquidating."
"As usual," remarked van Manderpootz. "Let's go over to the laboratory then."
The professor's quarters were but a block from the campus. He ushered me into the Physics Building, and thence into his own research laboratory, much like the one I had visited during my courses under him. The device--he called it his "subjunctivisor," since it operated in hypothetical worlds--occupied the entire center table. Most of it was merely a Horsten psychomat, but glittering crystalline and glassy was the prism of Iceland spar, the polarizing agent that was the heart of the instrument.
Van Manderpootz pointed to the headpiece. "Put it on," he said, and I sat staring at the screen of the psychomat. I suppose everyone is familiar with the Horsten psychomat; it was as much a fad a few years ago as the ouija board a century back. Yet it isn't just a toy; sometimes, much as the ouija board, it's a real aid to memory. A maze of vague and colored shadows is caused to drift slowly across the screen, and one watches them, meanwhile visualizing whatever scene or circumstances he is trying to remember. He turns a knob that alters the arrangement of lights and shadows, and when, by chance, the design corresponds to his mental picture--presto! There is his scene re-created under his eyes. Of course his own mind adds the details. All the screen actually shows are these tinted blobs of light and shadow, but the thing can be amazingly real. I've seen occasions when I could have sworn the psychomat showed pictures almost as sharp and detailed as reality itself; the illusion is sometimes as startling as that.
Van Manderpootz switched on the light, and the play of shadows began. "Now recall the circumstances of, say, a half-year after the market crash. Turn the knob until the picture clears, then stop. At that point I direct the light of the subjunctivisor upon the screen, and you have nothing to do but watch."
I did as directed. Momentary pictures formed and vanished. The inchoate sounds of the device hummed like distant voices, but without the added suggestion of the picture, they meant nothing. My own face flashed and dissolved and then, finally, I had it. There was a picture of myself sitting in an ill-defined room; that was all. I released the knob and gestured.
