But he knew this much; when the ship generated the frequencies which accelerated it beyond the speed of light, in effect the ship went into a sort of fourth dimension, and came out of it a good many light-years away. As far as Bart knew, no human being had ever survived warp-drive except in the suspended animation which they called cold-sleep. While the medic was professionally reassuring him and strapping him in his bunk, Bart wondered what humans would do with the Lhari star-drive if they had it. Well, he supposed they could use automation in their ships.

The Mentorian paused, needle in hand. "Do you wish to be wakened for the week we shall spend in each of the Proxima, Sirius and Pollux systems, sir? You can, of course, be given enough drug to keep you in cold-sleep until we reach the Procyon system."

Bart wondered if the room steward had mentioned the passenger so bored with the trip that he didn't even visit the Observation Lounge. He felt tempted—he was getting awfully tired of staring at the walls. On the other hand, he wanted very much to see the other star-systems. When he passed through them on the trip to Earth, he'd been too young to pay much attention.
