The Second Murray Leinster Megapack (119 page)

Burke seemed not to notice. He was busy. He thought very carefully, running through the information he’d received from the black cubes. He carefully refrained from thinking of the desperate necessity for a solution to the problem of the Enemy. If it was to be solved, it would be by a mind working without strain, just as a word that eludes the memory is best recalled when one no longer struggles to remember it.

Twice during the darkness Holmes regarded the blackness about them with suspicion, his hand on the small weapon Pam had passed to him. But nothing happened. There were sounds like bird calls, and songs like those of insects, and wind in the trees. But there was nothing else.

When gray first showed in the east, Burke shook himself. The jagged small moon rose hurriedly and floated across the sky.

“Holmes,” said Burke reflectively. “I think I’ve got what we want. You know how artificial gravity’s made, what the circuit is like.”

To anybody but Holmes and Keller, the comment would have seemed idiotic. It would have seemed insane even to them, not too long before. But Holmes nodded.

“Yes. Of course. Why?”

“There’s a chooser-circuit in the globes,” said Burke carefully, “that picks up radiation from an Enemy ship, and multiplies it enormously and beams it back. The circuit that made the radiation to begin with has to be resonant to it, as the globe burns it out while dashing down its own beam.”

“Naturally,” said Holmes. “What about it?”

“The point is,” said Burke, “that one could treat a suddenly increasing gravity-field as radiation. Not a stationary one, of course. But one that increased, fast. Like the gravity-fields of the Enemy ships, moving faster than light toward our sun.”

“Hmmmm,” said Holmes. “Yes. That could be done. But hitting something that’s traveling faster than light—”

“They’re traveling in a straight line,” said Burke, “except for orbiting around each other every few hours. There’s no faster-than-light angular velocity; just straight-line velocity. And with the artificial mass they’ve got, they couldn’t conceivably dodge. If we got some globes tricked up to throw a beam of gravity-field back at the Enemy ships, there might be resonance, and there’s a chance that one might hit, too.”

Holmes considered.

“It might take half an hour to change the circuit,” he observed. “Maybe less. There’d be no way in the world to test them. But they might work. We’d want a lot of them on the job, though, to give the idea a fair chance.”

Burke stood up, creaking a little from long immobility.

“Let’s hunt for the way back to the fortress,” he said. “There is a way. At least two crazy birds were marching around in the fortress’ corridors.”

Holmes nodded again. They began a search. Matter transposed from the fortress—specifically, the five of them—came out in a nearly three-walled alcove in the side of what had once been a magnificent building. Now it was filled with the trunks and stalks of trees and vines which grew out of every window-opening. There were other, similar alcoves, as if other matter-transposers to other outposts or other worlds had been centered here. They were looking for one that a plump, ridiculous bird might blunder into among the broken stones.

They found a metal plate partly arched-over by fallen stones in the very next alcove. They hauled at the tumbled rock. Presently the way was clear.

“Come along!” called Burke. “We’ve got a job to do! You girls want to fix breakfast and we want to get to work. We’ve a few hundred light-years to cross before we can have our coffee.”

Somehow he felt no doubt whatever. The five of them walked onto the corroded metal plate together, and the sky faded and ghosts of tube-lights appeared and became brilliant, and they stepped off the plate into a corridor one section removed from the sending-transposer which had translated them all, successively, to wherever they had been.

And everything proceeded matter-of-factly. The three men went to the room where metal globes by hundreds waited for the defenders of the fortress to make use of them. They were completely practical, those globes. There were even small footholds sunk into their moving sides so a man could climb to their tops and inspect or change the apparatus within.

On the way, Burke explained to Keller. The globes were designed to be targets, and targets they would remain. They’d be set out in the path of the coming Enemy ships, which could not vary their courses. Their circuits would be changed to treat the suddenly increasing gravitational fields as radiation, so that they would first project back a monstrous field of the same energy, and then dive down it to presumed collision with the ships. There was a distinct possibility that if enough globes could be gotten out in space, that at the least they might hit one enemy ship and so wreck the closely orbited grouping. From that reasonable first possibility, the chances grew slimmer, but the results to be hoped for increased.

Keller nodded, brightly. He’d used the reading helmets more than anybody else. He understood. Moreover, his mind was trained to work in just this field.

When they reached the room of the many spheres he gestured for Burke and Holmes to wait. He climbed the footholds of one globe, deftly removed its top, and looked inside. The conductors were three-inch bars of pure silver. He reached in and did this and that. He climbed down and motioned for Burke and Holmes to look.

It took them long seconds to realize what he’d done. But with his knowledge of what could be done, once he was told what was needed, he’d made exactly three new contacts and the globe was transformed to Burke’s new specifications.

Instead of days required to modify the circuits, the three of them had a hundred of the huge round weapons changed over within an hour. Then Keller went up to the instrument-room and painstakingly studied the launching system. He began the launchings while Holmes and Burke completed the change-over task. They joined him in the instrument-room when the last of the metal spheres rose a foot from the stony floor of the magazine and went lurching unsteadily over to the breech of the launching-tube they hadn’t noticed before.

“Three hundred,” said Keller in a pleased tone, later. “All going out at full acceleration to meet the Enemy. And there are six observer-globes in the lot.”

“Observers,” said Burke grimly. “That’s right. We can’t observe anything because the information would come back at the speed of light. But if we lose, the Enemy will arrive before we can know we’ve lost.”

Keller shook his head reproachfully.

“Oh, no! Oh, no! I just understood. There are transposers of electric energy, too. Very tiny. In the observers.”

Burke stared. But it was only logical. If matter could be transposed instead of transmitted between distant places, assuredly miniature energy-transposers were not impossible. The energy would no more travel than transposed matter would move. It would be transposed. The fortress would see what the observer-globes saw, at the instant they saw it, no matter what the distance!

Keller glanced at the ten-foot disk with its many small lights and the writhing bright-red sparks which were the Enemy gravity-ships. There was something like a scale of distances understood, now. The red sparks had been not far from the disk’s edge when the first space call went out to Earth. They were nearer the center when the spaceship arrived here. They were very, very near the center now.

“Five days,” said Burke in a hard voice. “Where will the globes meet them?”

“They’re using full acceleration,” Keller reminded him gently. “One hundred sixty gravities.”

“A mile a second acceleration,” said Burke. Somehow he was not astonished. “In an hour, thirty-six hundred miles per second. In ten hours, thirty-six thousand miles per second. If they hit at that speed, they’d smash a moon! They’ll cover half a billion miles in ten hours—but that’s not enough! It’s only a fifth of the way to Pluto! They won’t be halfway to Uranus!”

“They’ll have fifty-six hours,” said Keller. The need to communicate clearly made him almost articulate. “Not on the plane of the ecliptic. Their course is along the line of the sun’s axis. Meeting, seven times Pluto’s distance. Twenty billion miles. Two days and a half. If they miss we’ll know.”

Holmes growled, “If they miss, what then?”

“I stay here,” said Keller, mildly. “I won’t outlive everybody. I’d be lonely.” Then he gave a quick, embarrassed smile. “Breakfast must be ready. We can do nothing but wait.”

But waiting was not easy.

On the first day there came a flood of messages from Earth. Why had they cut off communication? Answer! Answer! Answer! What could be done about the Enemy ships? What could be done to save lives? If a few spaceships could be completed and take off before the solar system shattered, would the asteroid be shattered too? Could a few dozen survivors of Earth hope to make their way to the asteroid and survive there? Should the coming doom be revealed to the world?

The last question showed that the authorities of Earth were rattled. It was not a matter for Burke or Keller or Holmes to decide. They transmitted, in careful code, an exact description of the sending of the globes to try to intercept the Enemy gravity-ships. But it was not possible for people with no experiential knowledge of artificial gravity to believe that anything so massive as a sun could be destroyed by hurling a mere ten-foot missile at it!

Then there came a sudden revulsion of feeling on Earth. The truth was too horrible to believe, so it was resolved not to believe it. And therefore prominent persons broke into public print, denouncing Burke for having predicted the end of the world from his safe refuge in Asteroid M-387. They explained elaborately how he must be not only wrong but maliciously wrong.

But those denunciations were the first knowledge the public had possessed of the thing denounced. Some people instantly panicked because some people infallibly believe the worst, at all times. Some shared the indignation of the eminent characters who denounced Burke. Some were bewildered and many unstable persons vehemently urged everybody to do this or that in order to be saved. Get-rich-artists sold tickets in non-existent spacecraft they claimed had secrecy been built in anticipation of the disaster. They would accept only paper currency in small bills. What value paper money would have after the destruction of Earth was not explained, but people paid it. Astronomers swore quite truthfully that no telescope gave any sign of the alleged sun-sized masses en route to destroy Earth. Government officials heroically lied in their throats to reassure the populace because, after all, one didn’t want the half-civilized part of educated nations to run mad during Earth’s probable last few days.

And Burke and the others looked at the images sent back by the observer-globes traveling with the rest. The cosmos looked to the observer-globes just about the way it did from the fortress. There were innumerable specks of light of enumerable tints and colors. There was darkness. There was cold. And there was emptiness. The globe-fleet drove on away from the sun and from that flat plane near which all the planets revolve. Every second the spheres’ pace increased by one mile per second. Ten hours after Keller released them, they had covered five hundred eighty-eight thousand thousand miles and the sun still showed as a perceptible disk. Twenty hours out, the globes had traveled two billion six hundred million miles and the sun was the brightest star the observers could note. Thirty hours out, and the squadron of ten-foot globes had traveled five billion eight hundred thirty-odd million miles and the sun was no longer an outstanding figure in the universe.

Holmes looked fine-drawn, now, and Pam was fidgety. Keller appeared to be wholly normal. And Sandy was conspicuously calm.

“I’ll be glad when this is over,” she said at dinner in the ship in the lock-tunnel. “I don’t think any of you realize what this fortress and the matter-transposer and the planet it took us to—I don’t believe any of you realize what such things can mean to people.”

Burke waited. She smiled at him and said briskly, “There’s a vacant planet for people to move to. People occupied it once. They can do it again. Once it had a terrific civilization. This fortress was just one of its outposts. There were plenty of other forts and other planets, and the people had sciences away ahead of ours. And all those worlds, tamed and ready, are waiting right now for us to come and use them.”

Holmes said, “Yes? What happened to the people who lived on them?”

“If you ask me,” said Sandy confidentially, “I think they went the way of Greece and Rome. I think they got so civilized that they got soft. They built forts instead of fighting fleets. They stopped thinking of conquests and begrudged even thinking of defenses, though they had to, after a fashion. But they thought of things like the Rhine forts of the Romans, and Hadrian’s Wall. Like the Great Wall of China, and the Maginot Line in France. When men build forts and don’t build fighting fleets, they’re on the way down.”

Burke said nothing. Holmes waited for more.

“It’s my belief,” said Sandy, “that many, many centuries ago the people who built this fort sent a spaceship off somewhere with a matter-transposer on board. They replaced its crew while it traveled on and on, and they gave it supplies, and refreshed its air, and finally it arrived somewhere at the other side of the galaxy. And then the people here set up a matter-transposer and they all moved through it to the new, peaceful, lovely world they’d found. All except the garrison that was left behind. The Enemy would never find them there! And I think they smashed the matter-transposer that might have let the Enemy follow them—or the garrison of this fort, for that matter! And I think that away beyond the Milky Way there are the descendants of those people. They’re soft, and pretty, and useless, and they’ve likely let their knowledge die, and there probably aren’t very many of them left. And I think it’s good riddance!”
