<p>Forty hours later, Arcot was running the ship smoothly
at top speed once again. The four men had gone to bed
after more than thirty hours of hard work. That, coupled
with the exhaustion of working under four gravities, as they
had while the ship was going through the storm, was enough
to make them sleep soundly.</p>
<p>Arcot had awakened before the others and had turned
on the drive after resetting their course.</p>
<p>After that was done, there was little to do, and time
began to hang heavily on Arcot's hands. He decided to make
a thorough inspection of the hull when the others awoke.
The terrific strain might have opened cracks in the lux metal
hull that would not be detectable from the inside because
the inner wall was separated from the outer envelope.</p>
<p>Accordingly, he got out the spacesuits, making sure the
oxygen tanks were full and all was ready. Then he went
into the library, got out some books, and set about some
calculations he had in mind.</p>
<p>When Morey woke, some hours later, he found Arcot
still at work on his calculations.</p>
<p>"Hey!" he said, swinging himself into the chair beside
Arcot, "I thought you'd be on the lookout for more cosmic
rays!"</p>
<p>"Curious delusion, wasn't it?" asked Arcot blandly. "As
a matter of fact, I've been busy doing some figuring. I think
our chance of meeting another such region is about one
in a million million million million. Considering those chances,
I don't think we need to worry. I don't see how we ever
<SPAN name="Page_67" id="Page_67" />met <i>one</i>—but the chances of hitting one are better than
hitting two."</p>
<p>Just then Fuller stuck his head in the door.</p>
<p>"Oh," he said, "so you're at it already? Well, I wonder
if one of you could tell me just what it was we hit? I've
been so busy I haven't had a chance to think."</p>
<p>"Don't take the chance now, then," grinned Morey. "You
might strain your brain."</p>
<p>"<i>Please</i>!" Fuller pleaded, wincing. "Not before breakfast.
Just explain what that storm was."</p>
<p>"We simply came to a region in space where cosmic rays
are created," explained Arcot.</p>
<p>Fuller frowned. "But there's nothing out here to generate
cosmic rays!"</p>
<p>Arcot nodded. "True. I think I know their real source,
but I believe I'll merely say they are created here. I want
to do more work on this. My idea for an energy source
greater than any other in the universe has been confirmed.</p>
<p>"At any rate, they are created in that space, a perfect
vacuum, and the space there is distorted terrifically by the
titanic forces at work. It is bent and twisted far out of the
normal, even curvature, and it was that bumpy spot in space
that threw us about so.</p>
<p>"When we first entered, using the space-strain drive, the
space around the ship, distorted as it was, conflicted with
the region of the cosmic ray generation and the ship lost
out. The curvature of space that the ship caused was sometimes
reinforced and sometimes cancelled out by the twisted
space around it, and the tremendous surges of current back
and forth from the main power coil to the storage coils
caused the electric discharges that kept burning through the
air. I notice we all got a few burns from that. The field
was caused by the terrific surges of current, and that magnetic
field caused the walls of the ship to heat up due to
the generation of electric current in the walls."</p>
<p>Fuller looked around at the walls of the ship. "Well, the
<i>Ancient Mariner</i> sure took a beating."</p>
<p>"As a matter of fact, I was worried about that," said Arcot.
"<SPAN name="Page_68" id="Page_68" />Strong as that hull is, it might easily have been
strained in that field of terrific force. If it happened to
hit two 'space waves' at once, it might have given it an acceleration
in two different directions at once, which would
strain the walls with a force amounting to thousands of tons.
I laid out the suits up front, and I think we might reasonably
get out there and take a look at the old boat. When
Wade gets up—well, well—speak of the devil! My, doesn't
he look energetic?"</p>
<p>Wade's huge body was floating in through the library
door. He was yawning sleepily and rubbing his eyes. It
was evident he had not yet washed, and his growing beard,
which was heavy and black on his cheeks, testified to his
need for a shave. The others had shaved before coming
into the library.</p>
<p>"Wade," said Arcot, "we're going outside, and we have
to have someone in here to operate the airlock. Suppose you
get to work on the hirsute adornment; there's an atomic hydrogen
cutting torch down in the lab you can use, if you
wish. The rest of us are going outside." Then Arcot's voice
became serious. "By the way, don't try any little jokes like
starting off with a little acceleration. I don't think you would—you've
got good sense—but I like to make certain. If
you did, we'd be left behind, and you'd never find us in the
vast immensity of intergalactic space."</p>
<p>It wasn't a pleasant idea to contemplate. Each of the suits
had a radio for communication with each other and with the
ship, but they would only carry a few hundred miles. A
mere step in space!</p>
<p>Wade shook his head, grinning. "I have no desire to be
left all by myself on this ship, thank you. You don't
need to worry."</p>
<p>A few minutes later, Arcot, Morey, and Fuller stepped
out of the airlock and set to work, using power flashlights
to examine the outer hull for any signs of possible strain.</p>
<p>The flashlights, equipped as they were with storage coils
for power, were actually powerful searchlights, but in the
airlessness of space, the rays were absolutely invisible. They
<SPAN name="Page_69" id="Page_69" />could only be seen when they hit the relux inner wall at
such an angle that they were reflected directly into the observer's
eyes. The lux metal wall, being transparent, was
naturally invisible, and the smooth relux, reflecting one hundred
percent of the incident light, did not become illuminated,
for illumination is the result of the scattering of light.</p>
<p>It was necessary to look closely and pass the beams over
every square inch of the surface. However, a crack would
be rough, and hence would scatter light and be even more
readily visible than otherwise.</p>
<p>To their great relief, after an hour and a half of careful
inspection, none of them had found any signs of a crack,
and they went back into the ship to resume the voyage.</p>
<p>Again they hurled through space, the twin ghost ships
following them closely. Hour after hour the ship went on.
Now they had something else to do. They were at work calculating
some problems that Arcot had suggested in connection
with the velocities of motion that had been observed in
the stars at the edge of the island universe they were approaching.
Since these stars revolved about the mass of the
entire galaxy, it was possible to calculate the mass of the
entire universe by averaging the values from several stars.
Their results were not exact, but they were reliable enough.
They found the universe to have a mass of two hundred
and fifty million suns, only a little less than the home Galaxy.
It was an average-sized nebula.</p>
<p>Still the hours dragged as they came gradually nearer
their goal—gradually, despite their speed of twenty-four
light years per second!</p>
<p>At the end of the second day after their trouble with
the cosmic ray field, they stopped for observation. They
were now so near the Island Universe that the stars spread
out in a huge disc ahead of them.</p>
<p>"About three hundred thousand light years distant, I
should guess," said Morey.</p>
<p>"We know our velocity fairly accurately," said Wade. "Why
can't we calculate the distance between two of these stars
and then go on in?"</p>
<p>"<SPAN name="Page_70" id="Page_70" />Good idea," agreed Arcot. "Take the angle, will you,
Morey? I'll swing the ship."</p>
<p>After taking their measurements, they advanced for one
hour. Knowing this distance from experience, they were able
to calculate the diameter of this galaxy. It turned out to be
on the order of ninety thousand light years.</p>
<p>They were now much closer; they seemed, indeed, on the
very edge of the giant universe. The thousands of stars
flamed bright below them, stretching across their horizon
more and more—a galaxy the eyes of men had never before
seen at such close range! This galaxy had not yet
condensed entirely to stars, and in its heart there still remained
the vast gas cloud that would eventually be stars
and planets. The vast misty cloud was plainly visible, glowing
with a milky light like some vast frosted light bulb.</p>
<p>It was impossible to conceive the size of the thing; it
looked only like some model, for they were still over a quarter
of a million light years from it.</p>
<p>Morey looked up from his calculations. "I think we
should be there in about three hours. Suppose we go at
full speed for about two hours and then change to low
speed?"</p>
<p>"You're the astronomical boss, Morey," said Arcot. "Let's
go!"</p>
<p>They swung the ship about once more and started again.
As they drew nearer to this new universe, they began to
feel more interest in the trip. Things were beginning to
happen!</p>
<p>The ship plunged ahead at full speed for two hours.
They could see nothing at that velocity except the two
ghost ships that were their ever-present companions. Then
they stopped once more.</p>
<p>About them, they saw great suns shining. One was so
close they could see it as a disc with the naked eye. But
they could not see clearly; the entire sky was misty and the
stars that were not close were blotted out. The room seemed
to grow warm.</p>
<p>"<SPAN name="Page_71" id="Page_71" />Hey! Your calculations were off!" called Arcot. "We're
getting out of here!"</p>
<p>Suddenly the air snapped and they were traveling at
low speed under the drive of the space-strain apparatus.
The entire space about them was lit with a dim violet glow.
In ten minutes, the glow was gone and Arcot cut the drive.</p>
<p>They were out in ordinary dark space, with its star-studded
blackness.</p>
<p>"What was the matter with my calculations?" Morey wanted
to know.</p>
<p>"Oh, nothing much," Arcot said casually. "You were only
about thirty thousand light years off. We landed right in
the middle of the central gas cloud, and we were plowing
through it at a relative velocity of around sixteen thousand
miles per second! No wonder we got hot!</p>
<p>"We're lucky we didn't come near any stars in the process;
if we had, we could have had to recharge the coil."</p>
<p>"It's a wonder we didn't burn up at that velocity," said
Fuller.</p>
<p>"The gas wasn't dense enough," Arcot explained. "That
gas is a better vacuum than the best pump could give you
on Earth; there are fewer molecules per cubic inch than
there are in a radio tube.</p>
<p>"But now that we're out of that, let's see if we can
find a planet. No need to take photographs going in; if
we want to find the star again, we can take photos as we
leave. If we don't want to find it, we would just waste
film.</p>
<p>"I'll leave it to Morey to find the star we want."</p>
<p>Morey set to work at once with the telescope; trying to
find the nearest star of spectral type G-0, as had been agreed
upon. He also wanted to find one of the same magnitude,
or brilliance. At last, after investigating several such suns,
he discovered one which seemed to fulfill all his wishes. The
ship was turned, and they started toward the adventure they
had really hoped to find.</p>
<p>As they rushed through space, the distorted stars shining
vividly before them, they saw the one which was their
<SPAN name="Page_72" id="Page_72" />goal. A bright, slowly changing violet point on the cross-hairs
of the aiming telescope.</p>
<p>"How far is it?" asked Arcot.</p>
<p>"About thirty light centuries," replied Morey, watching
the star eagerly.</p>
<p>They drove on in silence. Then, suddenly, Morey cried
out: "Look! It's gone!"</p>
<p>"What happened?" asked Arcot in surprise.</p>
<p>Morey rubbed his chin in thought. "The star suddenly
flared brightly for an instant, then disappeared. Evidently,
it was a G-0 giant which had burned up most of the hydrogen
that stars normally use for fuel. When that happens,
a star begins to collapse, increasing in brilliance due to the
heat generated by the gas falling toward the center of the
star.</p>
<p>"Then other nuclear reactions begin to take place, and,
due to the increased transparency of the star, a supernova
is produced. The star blows away most of its gaseous envelope,
leaving only the superdense core. In other words, it leaves
a white dwarf." He paused and looked at Arcot. "I wonder
if that star did have any planets?"</p>
<p>They all knew what he meant. What was the probable
fate of beings whose sun had suddenly collapsed to a tiny,
relatively cold point in the sky?</p>
<p>Suddenly, there loomed before them the dim bulk of the
star, a disc already, and Arcot snapped the ship over to the
molecular motion drive at once. He knew they must be close.
Before them was the angry disc of the flaming white star.</p>
<p>Arcot swung the ship a bit to one side, running in close
to the flaming star. It was not exceedingly hot, despite the
high temperature and intense radiation, for the radiating
surface was too small.</p>
<p>They swung about the star in a parabolic orbit, for, at
their velocity, the sun could not hold them in a planetary
orbit.</p>
<p>"Our velocity, relative to this star, is pretty high," Arcot
announced. "I'm swinging in close so that I can use the
star's attraction as a brake. At this distance, it will be about
<SPAN name="Page_73" id="Page_73" />six gravities, and we can add to that a molecular drive braking
of four gravities.</p>
<p>"Suppose you look around and see if there are any planets.
We can break free and head for another star if there aren't."</p>
<p>Even at ten gravities of deceleration, it took several hours
to reduce their speed to a point which would make it possible
to head for any planet of the tiny sun.</p>
<p>Morey went to the observatory and swept the sky with
the telectroscope.</p>
<p>It was difficult to find planets because the reflected light
from the weak star was so dim, but he finally found one.
He took angular readings on it and on the central sun. A
little later, he took more readings. Because of the changing
velocity of the ship, the readings were not too accurate,
but his calculations showed it to be several hundred million
miles out.</p>
<p>They were decelerating rapidly, and soon their momentum
had been reduced to less than four miles a second.
When they reached the planet, Arcot threw the ship into
an orbit around it and began to spiral down.</p>
<p>Through the clear lux windows of the control room, the
men looked down upon a bleak, frozen world.</p>
