Their ship angled through jump-space along its calculated course. It kept its fragile human cargo warm, fed them and supplied breathable air. It had orders to worry about Brion's health, so it did, checking constantly against its recorded instructions and noting his steady progress. Another part of the ship's brain counted microseconds with moronic fixation, finally closing a relay when a predetermined number had expired in its heart. A light flashed and a buzzer hummed gently but insistently. Ihjel yawned, put away the report he had been reading, and started for the control room. He shuddered when he passed the room where Brion was listening to a playback of his Disan efforts. "Turn off that dying brontosaurus and get strapped in," he called through the thin door. "We're coming to the point of optimum possibility and we'll be dropping back into normal space soon." The human mind can ponder the incredible distances between the stars, but cannot possibly contain within itself a real understanding of them. Marked out on a man's hand an inch is a large unit of measure. In interstellar space a cubical area with sides a hundred thousand miles long is a microscopically fine division. Light crosses this distance in a fraction of a second. To a ship moving with a relative speed far greater than that of light, this measuring unit is even smaller. Theoretically, it appears impossible to find a particular area of this size. Technologically, it was a repeatable miracle that occurred too often to even be interesting. Brion and Ihjel were strapped in when the jump-drive cut off abruptly, lurching them back into normal space and time. They didn't unstrap, but just sat and looked at the dimly distant pattern of stars. A single sun, apparently of fifth magnitude, was their only neighbor in this lost corner of the universe. They waited while the computer took enough star sights to triangulate a position in three dimensions, muttering to itself electronically while it did the countless calculations to find their position. A warning bell chimed and the drive cut on and off so quickly that the two acts seemed simultaneous. This happened again, twice, before the brain was satisfied it had made as good a fix as possible and flashed a NAVIGATION POWER OFF light. Ihjel unstrapped, stretched, and made them a meal. Ihjel had computed their passage time with precise allowances. Less than ten hours after they arrived a powerful signal blasted into their waiting receiver. They strapped in again as the NAVIGATION POWER ON signal blinked insistently.
