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

Then once more they were racing toward Venone. Soon the giant star of which it was a planet loomed enormous. Then, at Morey’s direction, they swung, and before them loomed a planet. Large as Thett, near a half million miles in diameter, its mass was very closely equal to that of our sun. Yet it was but the burned-out sweepings of the outermost photospheric layers of this giant sun, and the radioactive atoms that made a sun active were not here; it was a cold planet. But its density was far, far higher than that of our sun, for our sun is but slightly denser than ordinary sea water. This world was dense as copper, for with the deeper sweepings of the tidal strains that had formed it, more of the heavier atoms had gone into its making, and its core was denser than that of Earth.

About it swept two gigantic satellite Worlds, each larger than Jupiter, but satellites of a satellite here! And Venone itself was inhabited by countless millions, yet their low, green tile and metal cities were invisible in the aspect of rolling lands with tiny hillocks, dwarfed by gigantic bulbous trees that floated their enormous weight in the water-dense atmosphere.

Here, too, there were no seas, for the temperature was above the critical temperature of water, and only in the self-cooling bodies of these men and in the trees which similarly cooled themselves, could there be liquid.

The sun of the world was another of the giant red stars, close to three hundred and fifty times the mass of our sun. It was circled by but three giant planets. Its enormous disc was almost invisible from the surface of the world as the Thought sank slowly through fifteen thousand miles of air, due to the screening effect on light passing through so much air. Earth could have rested on this planet and not extended beyond its atmosphere! Had Earth been situated at this planet’s center, the Moon could have revolved about it, and would not have been beyond the planet’s surface!

In silent wonder the terrestrians watched the titanic world as they sank, and their friends looked on amazed, comprehending even less of the significance of what they saw. Already within the titanic gravitational field, they could see that indescribable effects were being produced on them, and on the ship. Arcot alone could know the enormous gravitation, and his accelerometer told him now that he was subject to a gravitational acceleration of three thousand four hundred and eighty-seven feet per second, or almost exactly one hundred and nine times Earth’s pull.

“The Thought weighs one billion, two hundred and six million, five hundred thousand tons, with tender, on Earth. Here it weighs approximately one hundred and twenty-one billion tons,” said Arcot softly.

“Can you set it down? It may crush under this load if the gravity drive isn’t supporting it,” asked Torlos anxiously.

“Eight inches cosmium, and everything else supported by cosmium. I made this thing to stand any conceivable strain. Watch⁠—if the planet’s surface will take the load,” replied Arcot.

They were still sinking, and now a number of small marvelously streamlined ships were clustered around the slowly settling giant. In a few moments more people, hundreds, thousands of men were flying through the air up to the ship.

A cruiser had appeared, and was very evidently intent on leading them somewhere, and Arcot followed it as it streaked through the dense air. “No wonder they streamline,” he muttered as he saw the enormous force it took to drive the gigantic ship through this air. The air pressure outside their ship now was so great, that the sheer crushing effect of the air pressure alone was enormous. The pressure was well over nine tons to the square inch, on the surface of that enormous ship!

They landed approximately fifty miles from a large city which was the capital. The land seemed absolutely level, and the horizon faded off in distance in an atmosphere absolutely clear. There was no dust in the air at their height of nearly three hundred feet, for dust was too heavy on this world. There were no clouds. The mountains of this enormous world were not large, could not be large, for their sheer weight would tear them down, but what mountains there were were jagged, tortured rock, exceedingly sharp in outline.

“No rain⁠—no temperature change to break them down,” said Wade looking at them. “The zone of fracture can’t be deep here.”

“What, Wade, is the zone of fracture?” asked Torles.

“Rock has weight. Any substance, no matter how brittle, will flow if sufficient pressure is brought to bear from all sides. A thing which can flow will not break or fracture. You can’t imagine the pressure to which the rock three hundred feet down is subject to. There is the enormous mass of atmosphere, the tremendous mass of rock above, and all forced down by this gravitation. By the time you get down half a mile, the rock is under such an inconceivably great pressure that it will flow like mud. The rock there cannot break; it merely flows under pressure. Above, the rock can break, instead of flowing. That is the zone of fracture. On Earth the zone of fracture is ten miles deep. Here it must be of the order of only five hundred feet! And the planetary blocks that made a planet’s surface float on the zone of flowage⁠—they determine the zone of fracture.”

The gigantic ship had been sinking, and now, suddenly it gave a very unexpected demonstration of Wade’s words. It had landed, and Arcot shut off the power. There was a roaring, and the giant ship trembled, rocked, and rolled along a bit. Instantly Arcot drove it into the air.

“Whoa⁠—can’t do it. The ship will stand it, and won’t bend under the load⁠—but the planet won’t. We caused a Venone-quake. One of those planetary blocks Wade was talking about slipped under the added strain.”

Quickly Wade
