Invaders from the Infinite by John W. Campbell (well read books .txt) 📕

made on a world of huge size. Those men, their stocky, block legs and arms, their entire build and their desire for the largest of your planets, would indicate that. Their own world was probably even larger⁠—they were forced to wear pressure suits even on that large world, and could jump all over, you said. On so huge a sphere as their native world seems to be, the gravity would be so intense as to distort space. Geometry, such as yours seems to be, and such as ours was, could never be developed, for you assume the existence of a straight line, and of an absolute plane surface. These things cannot exist in space, but on small worlds, far from the central sun’s mass, the conditions approach that without sufficient discrepency to make the error obvious. On so huge a globe as their world the space is so curved that it is at once obvious that no straight line exists, and that no plane exists. Their geometry would never be like ours. When you went close to your sun, the attraction was sufficient to curve space into a semblance of the natural conditions on their home planet, then your senses and the ship met a compromise condition which made it seem more or less normal, not so obviously strange to you.

“But continue.” Arcot looked at Afthen interestedly.

“There were none left in their ship now, and we had been careful in locating the first hole, that it should not damage the propulsive machinery. The second hole was accidental, due to the shift of the machine. The machine itself was wrecked now, crushed by its own reaction. We forgot that any pencil of force powerful enough to do what we wanted, would tear the machine from its moorings unless fastened with great steel bolts into the solid rock.

“The second hole had been far to the rear, and had, by ill-luck, cut out a portion of the driving apparatus. We could not repair that, though we did succeed at last in lifting the great discs into place. We attempted to cut them, and put them back in sections. Our finest saws and machines did not nick them. Their weight was unbelievable, and yet we finally succeeded in lifting the things into the wall of the ship. The actual missing material did not represent more than a tiny cut, perhaps as wide as one of your credit-discs. You could slip the thin piece of metal in between them, but not so much as your finger.

“Those slots we welded tight with our best steel, letting a flap hang over on each side of the cut, and as the hot metal cooled, it was drawn against the shining walls with terrific force. The joints were perfectly airtight.

“The machines proper were repaired to the greatest possible extent. It was a heartbreaking task, for we must only guess at what machines should be connected together. Much damage had been done by the rushing air as it left, for it filled the machines, too, and they were not designed to resist the terrific air pressure that was on them when the pressure in the ship escaped. Many of the machines had been burst open, and these we could repair when we had the necessary elements and knew their construction from the remnants, or could find unbroken duplicates in the stock rooms.

“Once we connected the wrong things. This will show you what we dealt with. They were the wrong poles⁠—two generators, connected together in the wrong way. There was a terrific crash when the switch was thrown, and huge sheets of electric flame leaped from one of them. Two men were killed, incinerated in an instant, even the odors one might expect were killed in that flash of heat. Everything save the shining metal and clear glass within ten feet of it was instantly wiped out. And there was a fuse link that gave. The generator was ruined. One was left, and several small auxiliary generators.

“Eventually, we did the job. We made the machine work. And we are here.

“We have come to warn you, and to ask aid. Your system also has a large planet, slightly smaller than the largest of our system, but yet attractive. There are approximately 50,000 planetary systems in this universe, according to the records of the Invaders. Their world is not of this system. It is the World Thett, sun Antseck, Universe Venone. Where that is, or even what it means, we do not know. Perhaps you understand.

“But they investigated your world, and its address, according to their records, was World 3769⁠–⁠8482730⁠–⁠3. This, I believe, means, Universe 3769, sun 8482730, world 3. They have been investigating this system now for nearly three centuries. It was close to 200 years ago that they visited your world⁠—two hundred years of your time.”

“This is 2129⁠—which makes it about the year 1929⁠–⁠30 that they floated around here investigating. Why haven’t they done anything?” Arcot asked him.

“They waited for an auspicious time. They are afraid now, for recently they visited your world, and were utterly amazed to find the unbelievable progress your people have made. They intend to make an immediate attack on all worlds known to be intelligently populated. They had made the mistake of letting one race learn too much; they cannot afford to let it happen again.

“There are only twenty-one inhabited worlds known, and their thousands of scouts have already investigated nearly all the central mass of this universe, and much of the outer rings. They have established a base in this universe. Where I do not know. That, alone, was never mentioned in the records. But of all peoples, they feared only your world.

“There is one race in the universe far older than yours, but they are a sleeping people. Long ago their culture decayed. Still, now they are not far from you, and perhaps it will be worth the few days needed to learn more about them. We have their location and can take you
