"But this will require at least five days to get into working form. I suggest that in the meantime Venus makes several million of the long range Dis ray projectors, and distribute them all over the planet, to be turned on from a central station, or by their own separate crews. I have no doubt that the Sirians will attack that planet before we are ready to attack them. Earth, too, must be prepared. But in the meantime we can begin the work on the new de-activating field projectors, as I call them."
Waterson was right. It was three days later that the Sirian fleet left for Venus with a number of torpedo-ships so tremendous, it is absolutely inconceivable. There were over two hundred million of the ten-man machines! When they started to settle about Venus, the sky was so filled with them that it was literally dark for many miles. They attacked at Horacoles the System Capital, but the fields of the great Dis rays were too much for them. Neither bombs nor Dis rays could reach through. The air was dense, and filled with artificial smoke to prevent the transmission of heat rays and great winds were created for the purpose of carrying the heat away; but this was done automatically by the expanding air before long. They could not attack the city. All over the face of the planet were the great Dis ray emplacements. Great ships hung even over the great rolling oceans, sending the blue rays of ionized air up like some column that was to hold the Sirians from the Planet. And they did.
But now again they began to slow down the planet—not gently as they had had to before—but rapidly. The planet would have been pulled to pieces, except that the very attractor beams that were pulling on it tended to relieve the stress. But the cargo ships of Venus were pulling to keep the planet in motion. It was a strange thing to contemplate! Two mighty forces, one a fleet of two hundred million small ships, the other a force of as many thousand huge freight carriers, having a tug-o-war for a planet! But the odds were too great. Slowly the Sirians won. The planet was steadily dropping toward the sun. Now it seemed no fleet could come to aid them, and the Sirian fleet was being augmented constantly by a steady stream of ships from Mars. It was the sixth day after the announcement was made that Waterson had a fleet ready to attack the Sirians. The Venerians also had a fleet ready, prepared by the directions of Waterson's engineers sent by radio-television and radiophone. They were ready to attack, and the Terrestrian fleet arrived at Venus just six days after the announcement of the new weapon.
The practical projector of this new ray had been quite heavy, and they had been mounted in groups of twenty projectors on special hundred-man ships, using the same acceleration neutralizer used on the ten-man ships. They were arranged to throw a wide beam, so wide that the new ships with twenty, could prevent any action in a field of over two hundred miles depth, and in a cone with a base of six hundred miles diameter. The ships they had could approach within a hundred miles of the Sirian fleet, without being seen, for they were painted black therefore and showed no lights. In the darkness of the void they were easily hidden.
The entire expedition went as planned. The radio barrage had not been turned on, and they were in constant communication with the Venerians. The two fleets were to attack simultaneously, over different areas, so that between them they could wipe out so large a number of the enemy ships that the fleet of two million could easily handle the task.
Hidden in the utter dark of the void they crept up on the Sirians. They were in the sunlight, but the black coating kept them invisible, while the Sirian ships shone brilliantly. Then at last the tip of the great cone formation was within easy striking distance of the fleet. There reached out the strange ray, and here in space it was utterly invisible. But suddenly the ships within its range began to waver, to fall together under mutual gravitation. With one swoop they all shot toward the ships in space that had paralyzed them, for the attractor beams had been turned on them. As the great mass of ships fell rapidly toward them, long range Dis rays reached out, and they melted into clouds of shimmering dust. Great swaths were cut through their ranks. A similar scene was taking place far to the left of the Terrestrian fleet where the Venerian fleet was working havoc among the invaders. Now the last of the ships had been rayed into nothingness and a great fleet of the Sirians were rushing forward to attack for the ships invisible on account of their black line had been electrostatically located now. But as the Sirians came within one hundred miles of the other fleets, the ships all ceased to accelerate, to change direction; they just drifted straight into that cone of Dis rays. All walls of the de-activating field were lined with the ten-man ships, their shorter range Dis rays prevented any Sirians from escaping. Bright lights shone out on the Solarian fleet now—they wanted the Sirians to attack. The original cone formation had shifted rapidly; now it was a double cone; then it changed to a quadruple cone. There were six hundred of the de-activator ships and these were arranged so that they shot their rays off in four directions, making four cones of de-activated space, with the fleet of de-activator ships at the apex. Thus they were protected on all sides, and quickly, as the Sirian fleet spread out, more ships rose and there were six cones branching out. In the center rested the main mass of the fleet, the long range Dis ships, their attractors pointing out into the cones to draw the disabled ships of the Sirians into the range of their Dis rays, emanating in thousands from the ships lining the sides of the de-activated cones of space. The fleet was invulnerable and so sudden and complete was the failure of their power in these de-activated regions, that they did not seem to have time to warn their fellows. Many millions of the ships were lost before the wild charge could be checked; then the six-cone formation entire began to move slowly around; the Sirians, waiting to see what was to happen, were caught before they were aware that they were in danger. Many, too, were caught by the powerful attractor beams of the heavy ships within—drawn in by the greater power of the heavy ship, till their power failed. But at last the Sirians had learned the effective range of this new power and tried hard to avoid it. The six-cone formation was immediately broken up, and the six hundred de-activators went out individually, each followed by a swarm of the ten-man ships to disintegrate the ships caught in the de-activating cones. The Terrestrian ships were marked by a blazing blue light, so that if they too were caught in the de-activating field, they were not disintegrated. Only those around them were, and they were then released, as the ray did not seem to have any injurious effects on man, except to give him strange dreams. In some way the brain was stimulated by the ray, as long as the ray was used.
The de-activator ships were completely self-protecting; they could stop any number of attackers from any direction, provided the paralyzed ships were disintegrated as soon as caught, for if too many were piled up, the tendency of the matter to disintegrate in the engines, plus the natural tendency of the space to resume the normal curvature, caused the ray to become ineffective as it was overpowered, and one ship was lost in this way. Too many ships piled up, and only part of them could be rayed out by the ship itself, and there were not a sufficient number of helping ten-man ships. But the mighty fleet of the Sirians was already beaten. They still outnumbered us ten to one, but they could not fight this new force. They began a running fight to Mars, and now the Solarians were united. Rapidly they wiped out the edges of the fleet, and gradually worked in toward the center. But the Sirians could not fight back—they could use only the explosive shells, and few of them reached their goal. They were disintegrated, or missed. Not more than three thousand men were lost in that entire engagement.
But now the Solarians tried a plan to capture the Sphere. A large number of the ten-man ships dropped out of the main fleet, but not enough to make it noticeable to the hard-pressed Sirians. These were joined by one hundred of the de-activator ships. Then these, all capable of higher speeds than the main fleet, set out at the highest speed that could safely be maintained, and darted toward Mars. Undetected they rushed past the Sirian fleet and passed on toward Mars. They reached the planet fully three hours ahead of the main fleet. By the time the main fleet had arrived, it came unattended, for the last of the mighty fleet of two hundred million torpedo-ships had been turned to impalpable dust, floating in space.
The advance guard arrived without warning, and as they had expected, found the Sphere resting on the ground, protected by a great fleet of the torpedo-ships. There were nearly a million ships there, with the great machines rapidly making more. However, all were grouped in an area that could be covered by the cone of the de-activating beam. And out in space, the ship commanders decided on a plan. Fifty of the de-activator fleet took positions high above the Sirians, and the rest went with the entire fleet of the ten-man ships. These were to approach the camp from the ground. Lying close to the ground, they would be hard to see in the disappearing light. At a fixed moment, all the ships above were to turn on their de-activator rays, which would be plainly visible in the Martian atmosphere, while the ground fleet of fifty de-activators were to use their rays from the side. The ten-man ships were to form a circle around the camp at a safe distance from the de-activator rays, for they would crash when their power failed, if they were caught by the de-activator rays. But they wanted to capture the sphere in good condition, so they arranged to have the space directly above it unaffected by the de-activator field, lest some torpedo fall on it and destroy it. This would leave an exit for the torpedo-ships, except that at a point a mile or so above the Sphere, a cross-ray made escape impossible.
The rays were turned on. Instantly the fleet of nearly a million torpedo-ships fell wildly out of control, down through the blue glowing air, in which great streamers of glowing red seemed to waver and twist. Just outside the curtain of destruction waited the entire Solarian fleet. Slowly they closed in till their Dis rays swept all the ships within sixty miles of the edge out of existence; then rapidly the de-activator beams were forced ever sharper and sharper, till at last only the Sphere and a few hundred of the torpedo-ships, several hundred of the torpedo-ship constructors, and the corresponding cargo ships and worker machines were left. These had been saved for investigation by the scientists, for they were helpless.
But the war was over now. The Sirians had been destroyed, or reduced to mere museum pieces. Now the Scientists came to investigate the Sphere. There was much we wanted to learn from the creatures of the Sphere. But it was a strange story that the Sirian sphere had to tell.
Aeons ago there lived on a great planet of Sirius a race of intelligent men, shaped as we are, but smaller due to the greater gravity of their planet. And these men had developed a high civilization, a civilization different from ours, in that they learned early about mechanics, but chemistry and physics merely developed from the needs of the great mechanical engineers. Electricity was used as a powerful aid in their machines, and in their processes; it was a by-product, not an end.
Gradually their machines eliminated more and more of their work; they became more and more complicated, but more and more trustworthy. Men began to experiment with physics and found that their calculating machines needed development. It was easy to add first one step, then the next. More and more the machines could do. The mathematics became more and more complicated, and the machines developed the equations, found they could not handle them and passed them out as unfinished results. Finally one man used the machines to calculate the design of a machine that would be able to do these new equations. He built it, but the calculations were wrong. The machine had correctly solved his problem, but he had stated it wrong. It resulted in a machine that would solve only simple problems, but it did something no other machine had ever done. Given irrelevant data it would choose the correct facts and solve the problem. It was a step, a short step toward a machine that really thought.
Progress thereafter was rapid. The machines built machines, had been doing it for decades in fact, but now they did one thing more—they designed them. Now the problem could describe the type of machine needed, and the worker machine would design it, and turn out the completed machine! But these machines were rapidly perfecting the beginning that man had made. Within a decade after that first discovery of the principles of mechanical thought the machine was made that could not only solve problems, but could also originate them. They had developed a brain. It was a great machine, which occupied an entire building, with its massive framework bolted down to the ground.
Man began a rapid decline, for the machines did all his work. With the construction of a machine that could originate a problem, man made a mistake. He had created a machine that was more powerful than he, except that it was immobile. And this machine originated a new machine, a machine that would release the energy of matter! It had developed this because it had been able to see that such energy existed. Man's machines could have solved it long ago, but the problem had never been stated. Now came a machine that could state its own problems—and solve them.
And with this new energy it designed a new brain-machine. A brain machine such as no man's brain could conceive—a machine that could move! For it was powered by the energy of matter, and could move as no other machine had ever moved before—out into space!
Still the machines worked for the Sirian man, and he learned of the new discovery, and began to design a new brain-machine.
Some of the Sirians realized the danger that was facing them, and they had continued long researches on man's brain, and at last had discovered the secret of giving a machine that emotion we call devotion, loyalty, or gratitude. And they built a great machine on that principle and used material energy to power it. It was a success. It could think original thoughts. It pointed out the danger of the existing machines—they were stronger than man. It was only man's mobility and ability to control all mobile machines that had made him superior, for a brain without a tool, or body is helpless. And now that was lost. The existing brain-machines should be destroyed, and new ones built, using the principles that it was designed on.
But the mischief was done. The new brain-machine, designed by a machine, had done it. A machine had been built that was controlled by thoughts, a machine that could be controlled by the machines. Each of these machines was given a small brain, equipped with televisor sight and hearing, and it was powered by material energy. They could run for years without outside care, for the thinking machinery they had was sufficient to keep them oiled, and to make them seek repairs when they were damaged. They were susceptible to thought forces, and did as the thought waves suggested and reported to the control brain exactly what was going on about it.
And now this new brain developed a space-flyer to carry these machines, and man could not help knowing, for its every thought was recorded, for man's use. Then one day this record was found destroyed. The next day the brain-machine had left the planet, and taken with it the new space-flyer and the new telepathically controlled machines.
To the outermost planet of the System of Sirius the great machine fled. For years it remained there waiting, thinking. Then at last it called its worker machines into action. A new machine grew up from the stores of metal that the space ship had brought with it, at last the metal was used up, and the machine was not completed, so the space-flyer was sacrificed for the completion of the machine. The new machine was started. From its lip-like spout there poured a steady smooth stream of molten metal, and the rock on which it rested was eaten away. The first transmuting metal producer was made.
Decades passed, and only a small percentage of man developed. The rest sank deeper and deeper into a life of ease. The planets were all explored by the hardy ones, and no trace of the brain-machine was ever found, for it had discovered the Dis ray, and sunk deep into the ground, hollowing a great cave to live and work in.
But back on that planet, the scientists had developed machines that surpassed it in power, and finally one of these picked up a thought message from that distant machine that told its story. It was a thought that had not been consciously radiated, only the marvelous sensitivity of this new machine could have detected it, but now the men knew. It was too late to do much to prevent it, for they had no weapons. But the machine did. It was preparing to drive man from the planets, to rule there in his stead, with a population of machines!
The scientists quickly built a great space-flyer, a gigantic machine of over ten miles diameter, a huge sphere. And in that they established laboratories, workshops, machines, and living quarters. They took with them the finest men and women of their race, and sailed out into space, taking an orbit about the sun of Sirius. They were comfortable there in an equitable temperature, their ship lighted by the sun on one side, and dark on the other, steadily revolving on its axis like a miniature world. The foods of the people were chemically prepared, for the brain-machines had taught them how. The air was repurified constantly by machines that regulated the percentage of the gases to the thousandth of one per cent. But the entire ship was painted black. It could not be discovered floating there in space, so tiny in the vastness of a system!
It was two weeks after they sailed that the machine-brain attacked. It sailed out of its hiding place with thousands of great ships, armed with Dis rays and with explosives, with heat rays and attractor beams. The population of those worlds was wiped out in a week, and the rule of the Metal Horde began.
The original brain built other brain-machines to direct its affairs on other planets, and to do the work it did not wish to do itself.
For nearly a century those men lived in space, making swift forays on a planet with a fleet of cargo ships, that revolved about the main ship like satellites when they were not being used. In these trips they would bring back tons of rock, and leave most of it stored in the ships, dumping them into the reservoir of the parent ship when it was needed.
Then a swift ship was developed. A ship that could start and stop more quickly than any made before—a ship with acceleration neutralizers. But the machine brains of the Metal Horde never learned the secret. With a small fleet of these, the men drove an attack at the unprotected main brain-machine. There were no men known to live in the system. No other known machine could move without the knowledge of that main machine, but these could. They too had the Dis ray now, and they destroyed the main brain-machine. They were lost in the ensuing fight, but that machine was destroyed.
All the remaining machines were equally powerful. Any one of them could have built a brain-machine that could easily conquer the others—but it too would have to bow to its creator. They fought it out. The men had known this would be the result.
It was a war such as the system had never before seen. Each force was equal, and could not ally itself with any other, for the machines could not lie or state other than their thoughts, and each wanted supreme power. They developed new weapons, weapons whose strength lay in their number. One by one the machine brains had gone down to defeat, the men of that ship helping to disturb the balance of forces by ever so little, yet always enough to throw one side down to defeat, yet always remaining in hiding. At last there remained but one machine-brain, and its weakened force necessitated its return to the devastated planet. With the destruction of the other brain-machines, the remaining machines that they had previously controlled, automatically obeyed the new master as perfectly as they did the old.
They returned to find a new fleet awaiting them. But it was not a vast fleet such as they had encountered before. At once the torpedo-ship machines settled to the ground and began turning out their weapons. But it was all over before they could enter as an important factor. These ships had a new weapon. It was a ball of glowing blue light that was driven along a beam of some vibration, and as it touched any ship, the ship instantly volatized so suddenly as to constitute an explosion. The balls of light lasted about a minute and a half each, but were replaced as quickly as they were used. When they were finally used, they would die down to a dull red glow, then suddenly wink out. They could be swept from one ship to another, taking toll of ten or twelve ships each, and the beam that guided them could drive them with the speed of light and supply an infinite acceleration. They were glowing balls of concentrated energy of some sort, and as such could travel with the speed of light.
But they were effective to thenthdegree. The entire fleet of that one remaining brain-machine would have been lost, but it retired into space, racing away at top speed, out into space, with the remaining remnant of its great fleet.
And sixteen hundred years it had raced across space, to be destroyed at last by another race of men. The battle was over, and the machine awaited its destruction.
We rayed it out of existence. It was too great a menace to keep.
Some people still do not believe that those Sirians were truly machines. They can not believe that a machine can have intelligence, but certainly Waterson's calculating machine has intelligence of a sort. And they ask, what would a machine want to exist for? It would have no aim, nothing to perform. Why should it want to live, or exist?
We might ask what it is human beings want to live for. If there is an after-life, it is certainly not that that we live for. I am sure no man wants to die. Yet what aim have we? What function must we perform? Why should we wish to live? Our life is a constant struggle, the machines, at least, had eliminated that. There seems to me no reason why a machine should want to live, but certainly it has less reason to pass out of existence than we have!
That war was destructive—terribly so. But it has brought its compensations. More than fifteen million human beings lost their lives in that great struggle, either in the battles in space, or caught in the Dis rays during that battle on Venus.
But those fifteen millions have died a painless death, and twenty billions live because of their sacrifice. And it was not a vain sacrifice. We have learned much in return. No machines man ever made equaled the machines we captured there on Mars. And man will never experiment on the lines of the machine-brain. He has been warned. The brain-machine we captured was destroyed without investigation. The machines we use, the wonderful worker machines, have been modified to permit of radio control.
And Stephen Waterson's discovery of the de-activating field not only helps in law enforcement, but makes war with material energy impossible. No, in all, we have lost little.
Mars lost its cities, its forests, its ancient civilization. New cities are being built on the modern plan, larger, finer, more beautiful; the forests are being replaced; but the records, the relics of a civilization have been lost forever. In that we have lost much. Though all moveable things were moved when the warning came, there was much that could not be moved. The great palace of Horlak San was destroyed, but it is being rebuilt in the exact spot, in exactly the same manner. It is a worth-while project, but there is much which cannot be restored.
It will be eleven more years before we will know whether we can ever communicate with the Sirian men. The speed of light is too low for rapid communication, and as the first signals were sent out in September, 1961, and it is now September, 1968, the signals are not due to reach Sirius for two years more. Then it will be 1979 before we can hope to receive their reply. I often wonder if they will ever get those signals. I can remember distinctly the recoil of the great projector as the mighty surges of light flashed out across the universe. It seemed like some great gun—the back pressure of the light was so great. And what will those replies tell us? It is interesting to speculate on that subject.
The End
