<p>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.</p>
<p>And anything that surprised the team of Arcot, Wade,
and Morey was surprising indeed.</p>
<p>The intercom buzzed, interrupting their work.</p>
<p>Dr. Richard Arcot reached over and lifted the switch.
"Arcot speaking."</p>
<p>The face that flashed on the screen was businesslike and
<SPAN name="Page_8" id="Page_8" />determined. "Dr. Arcot, Mr. Fuller is here. My orders are
to check with you on all visitors."</p>
<p>Arcot nodded. "Send him up. But from now on, I'm not
in to anyone but my father or the Interplanetary Chairman
or the elder Mr. Morey. If they come, don't bother to call,
just send 'em up. I will not receive calls for the next ten
hours. Got it?"</p>
<p>"You won't be bothered, Dr. Arcot."</p>
<p>Arcot cut the circuit and the image collapsed.</p>
<p>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:</p>
<p>"If it isn't the late John Fuller. What did you do—take
a plane? It took you an hour to get here from Chicago."</p>
<p>Fuller shook his head sadly. "Most 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." Trying to suppress a grin,
Fuller bowed low. "Besides, I think it would do your royal
highness good to be kept waiting for a while. You're 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 want—and apologize if they
don't get it within twenty-four hours.</p>
<p>"No doubt about it; it will do your majesties good to
wait."</p>
<p>With a superior smile, he seated himself at the table and
shuffled calmly through the sheets of equations before him.</p>
<p>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.</p>
<p>"My friends," said Morey, almost tearfully, "I give you
the great Dr. Arcot. These countless machines we see have
come from one idea of his. Just an idea, mind you! And
<SPAN name="Page_9" id="Page_9" />who worked it into mathematical form and made it calculable,
and therefore useful? I did!</p>
<p>"And who worked out the math for the interplanetary
ships? I did! Without me they would never have been built!"
He turned dramatically, as though he were playing King
Lear. "And what do I get for it?" He pointed an accusing
finger at Arcot. "What do I get? <i>He</i> is called 'Earth's most
brilliant physicist', and I, who did all the hard work, am
referred to as 'his mathematical assistant'." He shook his head
solemnly. "It's a hard world."</p>
<p>At the table, Wade frowned, then looked at the ceiling.
"If you'd make your quotations more accurate, they'd be
more trustworthy. The news said that Arcot was the '<i>System's</i>
most brilliant physicist', and that you were the 'brilliant
mathematical assistant who showed great genius in developing
the mathematics of Dr. Arcot's new theory'." Having delivered
his speech, Wade began stoking his pipe.</p>
<p>Fuller tapped his fingers on the table. "Come on, you
clowns, knock it off and tell me why you called a hard-working
man away from his drafting table to come up to this
play room of yours. What have you got up your sleeve this
time?"</p>
<p>"Oh, that's too bad," said Arcot, leaning back comfortably
in his chair. "We're sorry you're so busy. We were
thinking of going out to see what Antares, Betelguese, or
Polaris looked like at close range. And, if we don't 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." Arcot looked at
Fuller sadly.</p>
<p>Fuller's eyes narrowed. He knew Arcot was kidding, but
he also knew how far Arcot would go when he was kidding—and
this sounded like he meant it. Fuller said: "Look,
teacher, a man named Einstein said that the velocity of
light was tops over two hundred years ago, and nobody's
come up with any counter evidence yet. Has the Lord instituted
a new speed law?"</p>
<p>"<SPAN name="Page_10" id="Page_10" />Oh, no," said Wade, waving his pipe in a grand gesture
of importance. "Arcot just decided he didn't like that law
and made a new one himself."</p>
<p>"Now <i>wait</i> a minute!" said Fuller. "The velocity of light
is a property of space!"</p>
<p>Arcot's bantering smile was gone. "Now you've got it,
Fuller. The velocity of light, just as Einstein said, is a property
of space. What happens if we change space?"</p>
<p>Fuller blinked. "Change space? How?"</p>
<p>Arcot pointed toward a glass of water sitting nearby.
"Why 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, <i>it slows down</i>.
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?"</p>
<p>"Oh," said Fuller softly. "I 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."</p>
<p>Arcot shook his head. "Take a look at the glass of water
again. What happens when the light comes <i>out</i> of the water?
It speeds up again <i>instantaneously</i>. 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
wouldn't feel it, any more than you'd feel the acceleration
due to gravity in free fall."</p>
<p>Fuller nodded slowly. Then, suddenly, a light gleamed in
his eyes. "I suppose you've figured out where you're going
to get the energy to power a ship like that?"</p>
<p>"He has," said Morey. "Uncle Arcot isn't the type to forget
a little detail like that."</p>
<p>"Okay, give," said Fuller.</p>
<p>Arcot grinned and lit up his own pipe, joining Wade in
an attempt to fill the room with impenetrable fog.</p>
<p>"<SPAN name="Page_11" id="Page_11" />All right," Arcot began, "we needed two things: a
tremendous source of power and a way to store it.</p>
<p>"For the first, ordinary atomic energy wouldn't do. It's
not controllable enough and uranium isn't something we could
carry by the ton. So I began working with high-density currents.</p>
<p>"At 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.</p>
<p>"I don't know why they didn't go on from there, but
they didn't. Possibly it was because they didn't 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.</p>
<p>"At any rate, I tried it, using <i>lux</i> metal as an insulator
around the wire."</p>
<p>"Hold it!" Fuller interrupted. "What, may I ask, is <i>lux</i>
metal?"</p>
<p>"That was Wade's idea," Arcot grinned. "You remember
those two substances we found in the Nigran ships during
the war?"</p>
<p>"Sure," said Fuller. "One was transparent and the other
was a perfect reflector. You said they were made of light—photons
so greatly condensed that they were held together
by their gravitational fields."</p>
<p>"Right. 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. <i>Lux</i> is the Latin for light, so he named
the transparent one <i>lux</i> and the reflecting one <i>relux</i>."</p>
<p>"It sounds peculiar," Fuller observed, "but so does every
coined word when you first hear it. Go on with your story."</p>
<p>Arcot relit his pipe and went on. "I put a current of ten
thousand amps through a little piece of lead wire, and
that gave me a current density of 10<sup>10</sup> amps per square inch.<SPAN name="Page_12" id="Page_12" /></p>
<p>"Then 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 anti-neutrons.</p>
<p>"Result: total annihilation of matter! When the contraterrene
lead atoms met the terrene lead atoms, mutual annihilation
resulted, giving us pure energy.</p>
<p>"Some of this power can be bled off to power the mechanism
itself; the rest is useful energy. We've got all the
power we need—power, literally by the ton."</p>
<p>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.</p>
<p>"The second thing," Arcot continued, "was, as I said, a
way to store the energy so that it could be released as rapidly
or as slowly as we needed it.</p>
<p>"That was Morey's baby. He figured it would be possible
to use the space-strain apparatus to store energy. It's
an old method; induction coils, condensers, and even gravity
itself are storing energy by straining space. But with Morey's
apparatus we could store a lot more.</p>
<p>"A torus-shaped induction coil encloses all its magnetic
field within it; the torus, or 'doughnut' coil, has a perfectly
enclosed magnetic field. We built an enclosed coil,
using Morey's principle, and expected to store a few watts
of power in it to see how long we could hold it.</p>
<p>"Unfortunately, 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.</p>
<p>"<SPAN name="Page_13" id="Page_13" />At any rate, the gadget can store power and plenty of
it, and it can put it out the same way."</p>
<p>Arcot knocked the ashes out of his pipe and smiled at
Fuller. "Those 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."</p>
<p>"Yes, sir! Right away, sir! Do you want a gross or only
a dozen?" Fuller asked sarcastically. "You sure believe in big
orders! And whence cometh the cold cash for this lovely
dream of yours?"</p>
<p>"That," said Morey darkly, "is where the trouble comes
in. We have to convince Dad. As President of Transcontinental
Airways, he's my boss, but the trouble is, he's 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, Arcot's dad
has a lot of influence around here, too, and I have a
healthy hunch he won't like the idea, either."</p>
<p>"I rather fear he won't," agreed Arcot gloomily.</p>
<p>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.</p>
<p>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.</p>
<p>Finally, Wade said: "I think we'll stand a much better
chance if we show them a big, spectacular exhibition; something
really impressive. We'll point out all the advantages
and uses of the apparatus. Then we'll show them complete
plans for the ship. They might consent."</p>
<p>"They might," replied Morey smiling. "It's worth a try,
anyway. And let's get out of the city to do it. We can go
up to my place in Vermont. We can use the lab up there
<SPAN name="Page_14" id="Page_14" />for all we need. We've got everything worked out, so
there's no need to stay here.</p>
<p>"Besides, I've got a lake up there in which we can indulge
in a little atavism to the fish stage of evolution."</p>
<p>"Good enough," Arcot agreed, grinning broadly. "And
we'll need that lake, too. Here in the city it's only eighty-five
because the aircars are soaking up heat for their molecular
drive, but out in the country it'll be in the nineties."</p>
<p>"To the mountains, then! Let's pack up!"</p>
