<p>Morey thought he was the first to waken when, seven hours
later, he dressed and dove lightly, noiselessly, out into the
library. Suddenly, he noticed that the telectroscope was in
operation—he heard the low hum of its smoothly working
director motors.</p>
<p>He turned and headed back toward the observatory. Arcot
was busy with the telectroscope.</p>
<p>"What's up, Arcot?" he demanded.</p>
<p>Arcot looked up at him and dusted off his hands. "I've
just been gimmicking up the telectroscope. We're going around
this dead dwarf once every three milliseconds, which
makes it awfully hard to see the stars around us. So I put
in a cutoff which will shut the telectroscope off most of the
time; it only looks at the sky once every three milliseconds.
As a result, we can get a picture of what's going on around
us very easily. It won't be a steady picture, but since we're
getting a still picture three hundred times a second, it will
be better than any moving picture film ever projected as
far as accuracy is concerned.</p>
<p>"I did it because I want to take a look at that bright
streak in the sky. I think it'll be the means to our salvation—if
there is any."</p>
<p>Morey nodded. "I see what you mean; if that's another
white dwarf—which it most likely is—we can use it to escape.
I think I see what you're driving at."</p>
<p>"If it doesn't work," Arcot said coolly, "we can profit by
the example of the people we left back there. Suicide is
preferable to dying of cold."</p>
<p><SPAN name="Page_92" id="Page_92" />Morey nodded. "The question is: How helpless are we?"</p>
<p>"Depends entirely on that star; let's see if we can get
a focus on it."</p>
<p>At the orbital velocity of the ship, focussing on the star
was indeed a difficult thing to do. It took them well over an
hour to get the image centered in the screen without its
drifting off toward one edge; it took even longer to get the
focus close enough to a sphere to give them a definite
reading on the instruments. The image had started out as a
streak, but by taking smaller and smaller sections of the
streak at the proper times, they managed to get a good,
solid image. But to get it bright enough was another problem;
they were only picking up a fraction of the light, and
it had to be amplified greatly to make a visible image.</p>
<p>When they finally got what they were looking for, Morey
gazed steadily at the image. "Now the job is to figure the
distance. And we haven't got much parallax to work with."</p>
<p>"If we compute in the timing in our blinker system at opposite
sides of the orbit, I think we can do it," Arcot said.</p>
<p>They went to work on the problem. When Fuller and
Wade showed up, they were given work to do—Morey gave
them equations to solve without telling them to what the
figures applied.</p>
<p>Finally Arcot said: "Their period about the common
center of gravity is thirty-nine hours, as I figure it."</p>
<p>Morey nodded. "Check. And that gives us a distance of
two million miles apart."</p>
<p>"Just what are you two up to?" asked Fuller. "What
good is another star? The one we're interested in is this
freak underneath us."</p>
<p>"No," Arcot corrected, "we're interested in getting <i>away</i>
from the one beneath us, which is an entirely different
matter. If we were midway between this star and that one,
the gravitational effects of the two would be cancelled out,
since we would be pulled as hard in one direction as the
other. Then we'd be free of both pulls and could escape!</p>
<p>"If we could get into that neutral area long enough to
turn on our space strain drive, we could get away between
<SPAN name="Page_93" id="Page_93" />them fast. Of course, a lot of our energy would be eaten
up, but we'd get away.</p>
<p>"That's our only hope," Arcot concluded.</p>
<p>"Yes, and what a whale of a hope it is," Wade snorted
sarcastically. "How are you going to get out to a point
halfway between these two stars when you don't have enough
power to lift this ship a few miles?"</p>
<p>"If Mahomet can not go to the mountain," misquoted
Arcot, "then the mountain must come to Mahomet."</p>
<p>"What are you going to do?" Wade asked in exasperation.
"Beat Joshua? He made the sun stand still, but this
is a job of throwing them around!"</p>
<p>"It is," agreed Arcot quietly, "and I intend to throw that
star in such a way that we can escape between the twin
fields! We can escape between the hammer and the anvil
as millions of millions of millions of tons of matter crash into
each other."</p>
<p>"And you intend to swing that?" asked Wade in awe as
he thought of the spectacle there would be when two suns
fell into each other. "Well, I don't want to be around."</p>
<p>"You haven't any choice," Arcot grinned. Then his face
grew serious. "What I want to do is simple. We have the
molecular ray. Those stars are hot. They don't fall into
each other because they are rotating about each other.
Suppose that rotation were stopped—stopped suddenly and
completely? The molecular ray acts catalytically; we won't
supply the power to stop that star, the star itself will. All
we have to do is cause the molecules to move in a direction
opposite to the rotation. We'll supply the impulse, and the
star will supply the energy!</p>
<p>"Our job will be to break away when the stars get close
enough; we are really going to hitch our wagon to a star!</p>
<p>"The mechanics of the job are simple. We will have to
calculate when and how long to use the power, and when and
how quickly to escape. We'll have to use the main power
board to generate the ray and project it instead of the little
ray units. With luck, we ought to be free of this star in
three days!"</p>
<p><SPAN name="Page_94" id="Page_94" />Work was started at once. They had a chance of life
in sight, and they had every intention of taking advantage of
it! The calculating machines they had brought would certainly
prove worth their mass in this one use. The observations
were extremely difficult because the ship was rocketing around
the star in such a rapid orbit. The calculations of the
mass and distance and orbital motion of the other star were
therefore very difficult, but the final results looked good.</p>
<p>The other star and this one formed a binary, the two
being of only slightly different mass and rotating about each
other at a distance of roughly two million miles.</p>
<p>The next problem was to calculate the time of fall from
that point, assuming that it would stop instantaneously, which
would be approximately true.</p>
<p>The actual fall would take only seven hours under the
tremendous acceleration of the two masses! Since the stars
would fall toward each other, the ship would be drawn toward
the falling mass, and since their orbit around the star
took only a fraction of a second to complete, they had to
make sure they were in the right position at the halfway
point just before collision occurred. Also, their orbit would
be greatly perturbed as the star approached, and it was
necessary to calculate that in, too.</p>
<p>Arcot calculated that in twenty-two hours, forty-six minutes,
they would be in the most favorable position to start the
fall. They could have started sooner, but there were some
changes that had to be made in the wiring of the ship before
they could start using the molecular ray at full power.</p>
<p>"Well," said Wade as he finally finished the laborious
computations, "I hope we don't make a mistake and get
caught between the two! And what happens if we find we
haven't stopped the star after all?"</p>
<p>"If we don't hit it exactly the first time," Morley replied,
"we'll have to juggle the ray until we do."</p>
<p>They set to work at once, installing the heavy leads to the
ray projectors, which were on the outside of the hull in
countersunk recesses. Morey and Wade had to go outside
the ship to help attach the cables.</p>
<p><SPAN name="Page_95" id="Page_95" />Out in space, floating about the ship, they were still
weightless, for they, too, were supported by centrifugal
force.</p>
<p>The work of readjusting the projectors for greater power
was completed in an hour and a quarter, which still left
over twenty hours before they could use them. During the
next ten hours, they charged the great storage coils to capacity,
leaving the circuits to them open, controlled by the
relays only. That would keep the coils charged, ready to
start.</p>
<p>Finally, Wade dusted off his hands and said: "We're
all ready to go mechanically, and I think it would be wise
if we were ready physically, too. I know we're not very tired,
but if we sit around in suspense we'll be as nervous as cats
when the time comes. I suggest we take a couple of sleeping
tablets and turn in. If we use a mild shock to awaken us,
we won't oversleep."</p>
<p>The others agreed to the plan and prepared for their wait.</p>
<p>Awakened two hours before the actual moment of action,
Wade prepared breakfast, and Morey took observations.
He knew just where the star should be according to their
calculations, and looked for it there. He breathed a sigh of
relief—it was exactly in place! Their mathematics they had
been sure of, but on such a rapidly moving machine, it was
exceedingly difficult to make good observations.</p>
<p>The two hours seemed to drag interminably, but at last
Arcot signalled for the full power of the molecular rays.
They waited, breathlessly, for some response. Nearly twenty
seconds later, the other sun went out.</p>
<p>"We did it!" said Wade in a hushed voice. It was almost
a shock to realize that this ship had power enough to extinguish
a sun!</p>
<p>Arcot and Morey weren't awed; they didn't have time.
There were other things to do and do fast.</p>
<p>They had checked the time required for them to see that
the white dwarf had gone out. Half of this gave them the
distance from the star in light seconds.</p>
<p>The screen had already been rigged to flash the information
<SPAN name="Page_96" id="Page_96" />into a computer, which in turn gave a time signal to
the robot pilot that would turn on the drive at precisely the
right instant. There was no time for human error here; the
velocities were too great and the time for error too small.</p>
<p>Then they waited. They had to wait for seven hours
spinning dizzily around an improbably tiny star with an
equally improbably titanic gravitational field. A star only a
couple of dozens of miles across, and yet so dense that
it weighed half a million times as much as the Earth! And
they had to wait while another star like it, chilled now to
absolute zero, fell toward them!</p>
<p>"I wish we could stay around to see the splash," Arcot
said. "It's going to be something to see. All the kinetic energy
of those two masses slamming into each other is going
to be a blaze of light that will really be something!"</p>
<p>Wade was looking nervously at the telectroscope plate.
"I wish we could see that other sun. I don't like the idea
of a thing that big creeping up on us in the dark."</p>
<p>"Calm down," Morey said quietly. "It's out of our hands
now; we took a chance, and it was a chance we <i>had</i> to take.
If you want to watch something, watch Junior down there.
It's going to start doing some pretty interesting tricks."</p>
<p>As the dense black sun approached them, Junior, as Morey
had called it, did begin to do tricks. At first they seemed
to be optical effects, as though the eye itself were playing
tricks. The red, glowing ball beneath them began to grow
transparent around its surface, leaving an opaque red core
which seemed to be shrinking slowly.</p>
<p>"What's happening?" Fuller asked.</p>
<p>"Our orbit around the star is becoming more and more
elliptical," Arcot replied. "As the other sun pulls us, the
star beneath us grows smaller with the distance; then, as
we begin to fall back toward it, it grows larger again.
Since this is taking place many hundreds of times per second,
the visual pictures all seem to blend in together."</p>
<p>"Watch the clock," Morey said suddenly, pointing.</p>
<p>The men watched tensely as the hand moved slowly around.</p>
<p>"<SPAN name="Page_97" id="Page_97" />Ten—nine—eight—seven—six—five—four—three—two—one—ZERO!"</p>
<p>A relay slammed home, and almost instantaneously, everyone
on the ship was slammed into unconsciousness.</p>
