The universe wreckers

by Edmond Hamilton

"It was evident, therefore, that the second force-ray would need to be shot out toward that star long before the first, since it was vitally necessary that the two rays strike their objects at the same moment.

"The first thing to do, therefore, was to prepare the great generators and send that second ray out toward Sagittarius. That work was begun at once, for only a short time was left us. On Triton's dark side, beneath the great roof, countless great generators were constructed, giant generators of the force-vibrations which could by their massed power produce a colossal ray of unthinkable power. Then a great pit or giant well was sunk in the roof, one whose sides sank down from the roof toward the surface of Triton. At the bottom of that great pit, on Triton's surface, was set the mighty mechanism or ray-concentrator that would send the gathered power of all the massed generators driving out into the great void in one colossal ray. That mechanism was, of course, upon Triton's surface, and was cut off from the rest of that surface by the metal walls that rose around it to the roof, since in that way it was possible to send the great ray out from Triton's surface through an opening in the great roof, the enclosing walls or sides of the pit preventing the warm air beneath the roof from escaping outward, and keeping it air-tight as ever.

"With that much done, the controls of the colossal ray and its generators were then constructed. Those controls were not single but were repeated no less than twenty times, there being a score of control-boxes for the great ray, set around the walls of the huge pit from which the ray would spring forth, and entered not from without but from within those walls, of course. A single control-box would have been enough, but our object in having a score of control-boxes was clear enough. It was a matter of life or death for all the Neptunian races that those controls should function properly. If this great second force-ray ceased but for a moment to go toward the star in Sagittarius, as mentioned, the backward pressure of the other great force-ray pressing against the sun would hurl Triton out of the solar system for all time, with all the Neptunians upon it. So those controls were not entrusted to a single control-box but were duplicated in twenty, so that if any one control-box was destroyed or harmed in any way, or even if a half-score or more were so destroyed or harmed, the great ray would continue to go forth.

"With that done, with the great generators ready, the ray-mechanism or opening ready, and the control-boxes and their intricate controls all completed, the first step was finished and there remained but to turn on the giant ray, to send it forth to that bright star in Sagittarius. So on the day that had been designated, the Neptunians to whom had been entrusted the all-important watch of the twenty controls, took their places in the control-boxes. The great ray-mechanism had been so placed in Triton's dark side, of course, that it pointed directly toward that star which the ray was to strike, and so it was needed only to turn on the giant ray. And so, at last, with all the Neptunians gathered there beneath the roof around the walls of the giant pit, staring through those walls, transparent from within, we gave the word. Then, as one, the twenty controls were opened, and from the gathered throbbing generators from the great ray-mechanism at the huge pit's bottom, there drove upward and outward into the great void of space the colossal force-ray, visible only near its source as pale light, flashing out at almost the speed of light itself, on its stupendous journey across the void toward that bright star in Sagittarius that was its goal!

"There was no push against Triton, of course, when that colossal ray went forth, for there could be no push against Triton until that ray struck a solid body, struck the star that was its goal, and then it would push back against Triton. Just as if you reach forth to push yourself away from a wall, there is no push on your body until your hand reaches the wall. Not until dozens of years had passed, we knew, would that great ray strike the star in Sagittarius that was its goal, and not until then would come the back-push against Triton, the bracing back-push that was its purpose. And in those dozens of years, with the great ray shot ceaselessly forth to that star, of course, Neptune and Triton themselves would be moving somewhat, would be moving as Neptune followed its slow orbit around the sun. But so slow and so vast is Neptune's orbit-movement, that it would have moved but little, and as it moved, the ray-mechanism would be turned constantly a very little so that its great ray would still be directed ceaselessly toward the star in Sagittarius, and so that when that ray struck that star, Neptune and Triton would be just between or in line with the sun and that distant star.

"Thus half of our great task was finished, and there remained but to complete the other half, to make ready for the sending forth of the other great force-ray, the first one as we called it, toward the sun. In the years that followed, while the great force-ray traveled ceaselessly, on and on through the great void, toward that distant star that was its goal, we Neptunians were busy here upon Triton with the making ready of the newer force-ray. On Triton's sunward side, directly opposite to the other force-ray's source, we constructed again the great generators that would be used for this newer ray, massing them there beneath the great roof. With those generators finished, we began again to construct a great pit or well in the roof, and to place at its bottom the ray-mechanism that would send this newer force-ray in through the solar system toward the sun.

"Terrible years were those for us, though now at last this terrible time approaches its end. For in those years we had not only to keep on the immense task of constructing generators and mechanisms for the newer force-ray, and to keep operating the other great generators and mechanisms that were sending forth ceaselessly the great force-ray toward Sagittarius; we had also to fight against the ever-encroaching cold that was deepening ever its dread menace over us, and that seemed on the point of overcoming us even as we reached the climax of our giant fight against doom. For ever that cold on Triton grew greater as it grew still cooler at its heart, and ever we must make greater and greater efforts to keep operating the innumerable heat-mechanisms that alone held death back from us. Yet we spurred ourselves onward by the thought that now at last we were approaching victory over this dread menace of cold that had beset us for so long, for at last the dozens of years required were drawing to an end and the great force-ray was fast nearing the star in Sagittarius that was its goal.

"So we labored on with all our strength, and soon the mechanisms of the new giant force-ray were finished, its great pit ready in Triton's sunward side, and the twenty control-boxes set in that pit's walls. Now at last was approaching the crucial moment of our great plan, that moment in which all must be calculated and performed with infinite care lest we meet disaster. The greatest of our scientists had many times, in those years, calculated the exact moment when the huge force-ray we had shot forth would meet at last the star in Sagittarius, would strike against that star. It was necessary that the other giant force-ray that we were to send forth against the sun would strike the sun's edge at the same moment exactly as the other ray struck that star, and with the same power exactly. So all was anxiety unutterable as we approached this great climax of our plan.

"By this time, scores of your Earth-days ago, Neptune in following its orbit had moved so that it was almost exactly between the sun and that distant star in Sagittarius toward which the ray was shooting. The fact that Triton revolved about Neptune did not impede that ray, of course, since as you know Triton moves about Neptune in an orbit slanted greatly, inclined greatly from the ecliptic, and so even when on the outer side of Neptune its ray would be able to go straight toward the sun, through the upper limits of Neptune's atmosphere, and so in the same way, even when it was on the sunward side of Neptune, its great ray, that we had sent forth years before, could shoot directly toward the star in Sagittarius. The only thing needful was that the ray we sent forth toward the sun be of the same power and strike it exactly when the other ray struck that distant star, so that they would push back against Triton with the same force at the same time.

"So in tense anxiety we remained and at last there came the moment for which we waited, more than four hours before the time when we calculated the other ray would strike the star in Sagittarius. And when that moment came the signal was given and the new mighty force-ray was shot forth, from Triton's sunward side, shot forth toward that edge of the sun turning away from us! That ray, of course, had no planets directly between it and the sun, we having chosen long before a time for the whole plan when this would not happen. But in the four hours and more that followed, we millions of Neptunians waited here on Triton with suspense unutterable. The moment was approaching when this giant force-ray would strike the sun. If we had calculated wrongly, if the other giant ray did not strike that star in Sagittarius at the same moment, Triton would be hurled out to doom in the great void by the sun-ray's pressure! Tensely we waited and then at last there came the moment for which we had waited. That moment came, and passed—that moment in which the new giant ray struck the sun—yet Triton did not move beneath its pressure.
