So Art tried that. As the car slowed, he began to lose weight, and his gorge began to rise in an exact correspondence. By the time the far door opened he was sweating and had somehow launched himself at the ceiling, where he hurt his wrist catching himself before hitting his head. Pain battled nausea, and the nausea was winning; it took him a couple of caroms to get to the control panel and hit the button to get him moving again, and back into the gravity ring. When the far door closed he settled gently back to the floor, and in a minute Martian gravity returned, and the door he had come in through reopened. He bounced gratefully out, suffering no more than the pain of a sprained wrist. Nausea was far more unpleasant than pain, he reflected— at least certain levels of pain. He would have to get his outside view over the TVs.

He would not be lonely. Most of the passengers and all of the crew spent the majority of their time in the gravity ring, which was therefore fairly crowded, like a full hotel in which most of the guests spent most of their time in the restaurant and bar. Art had seen and read accounts of the continuous shuttles that made them seem like flying Monte Carlos, with permanent residents made up of the rich and bored; a popular vid series had had just such a setting. Art’s ship, the Ganesh, was not like that. It was clear that it had been hurtling around the inner solar system for a good long time now, and always at full capacity; its interiors were getting shabby, and when restricted to the ring it seemed very small, much smaller than the impression one had of these kinds of ships from watching history shows about the Ares. But the First Hundred had lived in about five times as much space as the Ganesh’s g ring, and the Ganesh carried five hundred passengers.
