Islands Of Space
I
Three men sat around a table which was littered with graphs, sketches of mathematical functions, and books of tensor formulae. Beside the table stood a Munson-Bradley integraph calculator which one of the men was using to check some of the equations he had already derived. The results they were getting seemed to indicate something well above and beyond what they had expected.
And anything that surprised the team of Arcot, Wade, and Morey was surprising indeed.
The intercom buzzed, interrupting their work.
Dr. Richard Arcot reached over and lifted the switch. âArcot speaking.â
The face that flashed on the screen was businesslike and determined. âDr. Arcot, Mr. Fuller is here. My orders are to check with you on all visitors.â
Arcot nodded. âSend him up. But from now on, Iâm not in to anyone but my father or the Interplanetary Chairman or the elder Mr. Morey. If they come, donât bother to call, just send âem up. I will not receive calls for the next ten hours. Got it?â
âYou wonât be bothered, Dr. Arcot.â
Arcot cut the circuit and the image collapsed.
Less than two minutes later, a light flashed above the door. Arcot touched the release, and the door slid aside. He looked at the man entering and said, with mock coldness:
âIf it isnât the late John Fuller. What did you doâ âtake a plane? It took you an hour to get here from Chicago.â
Fuller shook his head sadly. âMost of the time was spent in getting past your guards. Getting to the seventy-fourth floor of the Transcontinental Airways Building is harder than stealing the Taj Mahal.â Trying to suppress a grin, Fuller bowed low. âBesides, I think it would do your royal highness good to be kept waiting for a while. Youâre paid a couple of million a year to putter around in a lab while honest people work for a living. Then, if you happen to stub your toe over some useful gadget, they increase your pay. They call you scientists and spend the resources of two worlds to get you anything you wantâ âand apologize if they donât get it within twenty-four hours.
âNo doubt about it; it will do your majesties good to wait.â
With a superior smile, he seated himself at the table and shuffled calmly through the sheets of equations before him.
Arcot and Wade were laughing, but not Robert Morey. With a sorrowful expression, he walked to the window and looked out at the hundreds of slim, graceful aircars that floated above the city.
âMy friends,â said Morey, almost tearfully, âI give you the great Dr. Arcot. These countless machines we see have come from one idea of his. Just an idea, mind you! And who worked it into mathematical form and made it calculable, and therefore useful? I did!
âAnd who worked out the math for the interplanetary ships? I did! Without me they would never have been built!â He turned dramatically, as though he were playing King Lear. âAnd what do I get for it?â He pointed an accusing finger at Arcot. âWhat do I get? He is called âEarthâs most brilliant physicistâ, and I, who did all the hard work, am referred to as âhis mathematical assistant.âââ He shook his head solemnly. âItâs a hard world.â
At the table, Wade frowned, then looked at the ceiling. âIf youâd make your quotations more accurate, theyâd be more trustworthy. The news said that Arcot was the âSystemâs most brilliant physicistâ, and that you were the âbrilliant mathematical assistant who showed great genius in developing the mathematics of Dr. Arcotâs new theoryâ.â Having delivered his speech, Wade began stoking his pipe.
Fuller tapped his fingers on the table. âCome on, you clowns, knock it off and tell me why you called a hardworking man away from his drafting table to come up to this play room of yours. What have you got up your sleeve this time?â
âOh, thatâs too bad,â said Arcot, leaning back comfortably in his chair. âWeâre sorry youâre so busy. We were thinking of going out to see what Antares, Betelguese, or Polaris looked like at close range. And, if we donât get too bored, we might run over to the giant model nebula in Andromeda, or one of the others. Tough about your being busy; you might have helped us by designing the ship and earned your board and passage. Tough.â Arcot looked at Fuller sadly.
Fullerâs eyes narrowed. He knew Arcot was kidding, but he also knew how far Arcot would go when he was kiddingâ âand this sounded like he meant it. Fuller said: âLook, teacher, a man named Einstein said that the velocity of light was tops over two hundred years ago, and nobodyâs come up with any counter evidence yet. Has the Lord instituted a new speed law?â
âOh, no,â said Wade, waving his pipe in a grand gesture of importance. âArcot just decided he didnât like that law and made a new one himself.â
âNow wait a minute!â said Fuller. âThe velocity of light is a property of space!â
Arcotâs bantering smile was gone. âNow youâve got it, Fuller. The velocity of light, just as Einstein said, is a property of space. What happens if we change space?â
Fuller blinked. âChange space? How?â
Arcot pointed toward a glass of water sitting nearby. âWhy do things look distorted through the water? Because the light rays are bent. Why are they bent? Because as each wave front moves from air to water, it slows down. The electromagnetic and gravitational fields between those atoms are strong enough to increase the curvature of the space between them. Now, what happens if we reverse that effect?â
âOh,â said Fuller softly. âI get it. By changing the curvature of the space surrounding you, you could get any velocity you wanted. But what about acceleration? It would take years to reach those velocities at any acceleration a man could stand.â
Arcot shook his head. âTake a look at the glass of water again. What happens when the light comes out of the water? It speeds up again instantaneously. By changing the space around a spaceship, you instantaneously change the velocity of the ship to a comparable velocity in that space. And since every particle is accelerated at the same rate, you wouldnât feel it, any more than youâd feel the acceleration due to gravity in free fall.â
Fuller nodded slowly. Then, suddenly, a light gleamed in his eyes. âI suppose youâve figured out where youâre going to get the energy to power a ship like that?â
âHe has,â said Morey. âUncle Arcot isnât the type to forget a little detail like that.â
âOkay, give,â said Fuller.
Arcot grinned and lit up his own pipe, joining Wade in an attempt to fill the room with impenetrable fog.
âAll right,â Arcot began, âwe needed two things: a tremendous source of power and a way to store it.
âFor the first, ordinary atomic energy wouldnât do. Itâs not controllable enough and uranium isnât something we could carry by the ton. So I began working with high-density currents.
âAt the temperature of liquid helium, near absolute zero, lead becomes a nearly perfect conductor. Back in nineteen twenty, physicists had succeeded in making a current flow for four hours in a closed circuit. It was just a ring of lead, but the resistance was so low that the current kept on flowing. They even managed to get six hundred amperes through a piece of lead wire no bigger than a pencil lead.
âI donât know why they didnât go on from there, but they didnât. Possibly it was because they didnât have the insulation necessary to keep down the corona effect; in a high-density current, the electrons tend to push each other sideways out of the wire.
âAt any rate, I tried it, using lux metal as an insulator around the wire.â
âHold it!â Fuller interrupted. âWhat, may I ask, is lux metal?â
âThat was Wadeâs idea,â Arcot grinned. âYou remember those two substances we found in the Nigran ships during the war?â
âSure,â said Fuller. âOne was transparent and the other was a perfect reflector. You said they were made of lightâ âphotons so greatly condensed that they were held together by their gravitational fields.â
âRight. We called them light-metal. But Wade said that was too confusing. With a specific gravity of 103.5, light-metal was certainly not a light metal! So Wade coined a couple of words. Lux is the Latin for light, so he named the transparent one lux and the reflecting one relux.â
âIt sounds peculiar,â Fuller observed, âbut so does every coined word when you first hear it. Go on with your story.â
Arcot relit his pipe and went on. âI put a current of ten thousand amps through a little piece of lead wire, and that gave me a current density of 1010 amps per square inch.
âThen I started jacking up the voltage, and modified the thing with a double-polarity field somewhat similar to the molecular motion field except that it works on a sub-nucleonic level. As a result, about half of the lead fed into the chamber became contraterrene lead! The atoms just turned themselves inside out, so to speak, giving us an atom with positrons circling a negatively charged nucleus. It even gave the neutrons a reverse spin, converting them into antineutrons.
âResult: total annihilation of matter! When the contraterrene lead atoms met the terrene lead atoms, mutual annihilation resulted, giving us pure energy.
âSome of this power can be bled off to power the mechanism itself; the rest is useful energy. Weâve got all the power we needâ âpower, literally by the ton.â
Fuller said nothing; he just looked dazed. He was well beginning to believe that these three men could do the impossible and do it to order.
âThe second thing,â Arcot continued, âwas, as I said, a way to store the energy so that it could be released as rapidly or as slowly as we needed it.
âThat was Moreyâs baby. He figured it would be possible to use the space-strain apparatus to store energy. Itâs an old method; induction coils, condensers, and even gravity itself are storing energy by straining space. But with Moreyâs apparatus we could store a lot more.
âA torus-shaped induction coil encloses all its magnetic field within it; the torus, or âdoughnutâ coil, has a perfectly enclosed magnetic field. We built an enclosed coil, using Moreyâs principle, and expected to store a few watts of power in it to see how long we could hold it.
âUnfortunately, we made the mistake of connecting it to the city power lines, and it cost us a hundred and fifty dollars at a quarter of a cent per kilowatt hour. We blew fuses all over the place. After that, we used the relux plate generator.
âAt any rate, the gadget can store power and plenty of it, and it can put it out the same way.â
Arcot knocked the ashes out of his pipe and smiled at Fuller. âThose are the essentials of what we have to offer. We give you the job of figuring out the stresses and strains involved. We want a ship with a cruising radius of a thousand million light years.â
âYes, sir! Right away, sir! Do you want a gross or only a dozen?â Fuller asked sarcastically. âYou sure believe in big orders! And whence cometh the cold cash for this lovely dream of yours?â
âThat,â said Morey darkly, âis where the trouble comes in. We have to convince Dad. As President of Transcontinental Airways, heâs my boss, but the trouble is, heâs also my father. When he hears that I want to go gallivanting off all over the Universe with you guys, he is very likely to turn thumbs down on the whole deal. Besides, Arcotâs dad has a lot of influence around here, too, and I have a healthy hunch he wonât like the idea, either.â
âI rather fear he wonât,â agreed Arcot gloomily.
A silence hung over the room that felt almost as heavy as the pall of pipe smoke the air conditioners were trying frantically to disperse.
The elder Mr. Morey had full control of their finances. A ship that would cost easily hundreds of millions of dollars was well beyond anything the four men could get by themselves. Their inventions were the property of Transcontinental, but even if they had not been, not one of the four men would think of selling them to another company.
Finally, Wade said: âI think weâll stand a much better chance if we show them a big, spectacular exhibition; something really impressive. Weâll point out all the advantages and uses of the apparatus. Then weâll show them complete plans for the ship. They might consent.â
âThey might,â replied Morey smiling. âItâs worth a try, anyway. And letâs get out of the city to do it. We can go up to my place in Vermont. We can use the lab up there for all we need. Weâve got everything worked out, so thereâs no need to stay here.
âBesides, Iâve got a lake up there in which we can indulge in a little atavism to the fish stage of evolution.â
âGood enough,â Arcot agreed, grinning broadly. âAnd weâll need that lake, too. Here in the city itâs only eighty-five because the aircars are soaking up heat for their molecular drive, but out in the country itâll be in the nineties.â
âTo the mountains, then! Letâs pack up!â
