Part 4

Then at last we understood the reason for this tremendous number of inoffensive worker machines. There was a great seething mass of metal around the workings now. Great blazing lights illuminated the scene as brightly as day. There was a great horde of shining metal machines working swiftly about the great plain. There seemed to be thousands of them now, and they were all busily at work on great machines--the torpedo-ship machines! There must have been nearly a thousand already completed and already the fleet that had escaped had been built up to many thousands by the rapidly working machines, and a steady stream of long glistening shapes rose--only to be lost in the darkness beyond. Steadily the great machines were being put together, and steadily the great fleet was being augmented.

Before morning that fleet had reached two hundred thousand, and was now growing at the rate of twenty-five thousand an hour. Steadily this rate was increasing. The fleet was too large to be attacked by man's weakened fleet, for the delay in putting Venus back in its orbit had given the Sirians a chance to build up an invulnerable fleet. The added time of the trip to Mars meant a still greater fleet. Already their production-rate was far greater than Man's. Man could not hope to compete successfully. We were learning the meaning of quantity production.

Had it been possible to attack them with the long range Dis rays it would have been tried, but the plan was hopeless. Before the fleet could reach them there would be 100,000,000 miles to go to reach them, and it would take approximately twenty hours, in which time, at the present rate of increase, the Sirian fleet would have reached a total of three million again. They would all concentrate their attack on the long range Dis ray ships. No Solarian ships could help without interfering with the action of the Dis ray ships, and they would need help, for each ship carried only two beams. More could not be carried. They would merely be held at bay, unable to attack their goal, useful only in breaking up the spinning sphere formation, but that could be prevented. The Solarians had learned that trick from the Sirians. The Sirians had succeeded in breaking up every spinning column formation by simply getting into the midst of it before it was formed completely. It required perfect coordination of several machines to do it, but it was always done. The long range Dis rays were excellent now in defending a city, but useless for attack because of the terrific weight of the apparatus. They could not attack the Sirian fleet. If they did the production machines would have been so built up by the time they reached the planet that any ordinary rate of destruction would be easily equaled by the production! Within three days it was decided that the Sirian fleet would be built up enough to attack. They would then attack our planets, no doubt.

A cabinet meeting was called at the Waterson laboratories on Earth. There Waterson first demonstrated the weapon that finally conquered in the terrific struggle. Before the members, on the Cabinet table, was a small portable material energy disintegrator, a machine that gave off its energy as light. There was a second machine at the other end of the table, a machine that occupied about two cubic feet of space, and on one side of it was a small switch and a dial; on the other was a familiar looking projector.

Dr. Waterson spoke:

"Gentlemen of the Cabinet: I have here a new machine that my laboratory has developed. I will demonstrate its action first." The light was switched on, throwing a brilliant shaft of light against the ceiling. Then Waterson snapped on the switch of the new machine, and there appeared a strange beam of blueish, ionized air. But unlike any other known ionizing beam, it was shot through with streamers of red fire, long, hair-thin streamers that wavered and flickered in the blue tube of the ionized air. It reached out, touched the light generator, and passed on, through a series of plates of different materials. But the instant that strange beam struck the light-machine, it went out. Then a moment later, when the new machine was turned off, the light snapped back on.

"Gentlemen, this machine will produce a field, directional in this case, that will so modify the properties of space as to make it utterly impossible to disintegrate matter into energy. There is some tendency to fix energy as matter. I think that will be interesting to us in the event that this war is successfully concluded. But at present we are interested in the properties of the beam in that it will stop the disintegration of matter. The process depends on the modification of the properties of space. It is well known that in ordinary space, such as we know, there are twenty coefficients of curvature. In ordinary empty space, ten of these have zero values, and the ten principal coefficients have certain non-zero values. This machine so affects space that it makes all the coefficients of space have non-zero values, and fixes these values to suit its own purposes. The results are amazing. I have done some things with this machine that makes me truly afraid. But we are interested in it because certain of the values we can assign operate to force space to take such curvatures, that any change of the condition of matter to condition of energy is impossible. On release of the ray, the space returns to its normal curvature.

"Working out the theory of this machine has been a tremendous task. Even the great calculating machine, the new integraph developed last year, and it is a far cry from that first one that M.I.T. developed in 1927, required many weeks of work to solve the problem in twenty coefficients of space. In so doing at one stage we had to assume a space of twenty dimensions in order that the correct values in the four true dimensions might be determined.

"But there is still a great deal of work to be done. We must develop practical machines of a range of many miles. There is no difficulty in using the ray, since, as it is a condition of space, not a vibration, it is impossible to stop it by any shield. There is only one way to work with it, to create it directionally. We make the field by projecting certain strains along a beam, then once started the field follows that line to a distance dependent on the strength of the generator.

"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.
