Their velocity had been five thousand miles per second when they entered hyperspace, and they were swiftly adding to their original velocity. They did not, of course, feel the pull of the sun, since they were in free fall in its field; they could only feel the five and a half gravities of the molecular drive.
Hence it must be, viz, because our sisters are too much occupied with the playful things of this earth, and our brothers with its gravities, that neither party sufficiently watches the skies.
"Nope!" Arcot said grimly. "I want a couple of those ships, and I'm going to get them!" At four gravities of acceleration, the Ancient Mariner drove after the fleeing ships of Sator, but the enemy ships soon dropped rapidly from sight. Twenty five thousand miles out in space, Arcot cut the acceleration. "We'll catch them now, I think," he said softly.
She started for it at four gravities acceleration, and Joe got his headphones to his ears and lay panting while he waited for the figures and information he had to have. He got them. When the four-gravity rockets burned out, the tug's crew painstakingly adjusted the ship's nose to a certain position. They flung themselves back into the acceleration chairs and Joe fired a six-g blast.
He would expect guided missiles but he probably wouldn't expect to be attacked by space wagons. Joe said suddenly: "Chief! I'm going to burn a twelve-two. We've got to match velocities coming back. Join me? Three two one." He fired a twelve-two. Twelve seconds burning, two gravities acceleration. It built up his speed away from the Platform to a rate which would have been breathless, on Earth.
Then the walls drew back, straining against their netting, and Joe waited for the door to open to empty space. Instead, there came a sharp voice in his helmet-phones. It was Brown. "Radar says there's a rocket on the way up! It's over at what is the edge of the world from here. Three gravities only. Better not go out!" Joe hesitated. Brown still issued no order.
The feeling of deceleration increased. For part of a second they had the sensation of three gravities. Then there was a curious, yielding jar really very slight and then the feeling of excess weight ended altogether. But not the feeling of weight. They still had weight. It was constant. It was steady. But it was very slight. They were on the moon, but Cochrane felt no elation.
An objection to the foregoing theory will, perhaps, be drawn from the plutonic rocks not being separated into two evidently distinct series, of different specific gravities; although, like the volcanic, they have been liquified.
Acceleration-chairs of remarkably effective design, plus the pre-saturation of one's blood with oxygen, made so high an acceleration safe and not unendurable for the necessary length of time it lasted. Now, at three gravities, one did not feel on the receiving end of a violent thrust, but one did feel utterly worn out and spent.
"And the sum of the specific gravities of these two substances is 10, precisely the number that represents Gallia's density." "A comet of gold!" ejaculated the captain. "Yes; a realization of what the illustrious Maupertuis has already deemed probable," replied the astronomer.
