“Unless an expedition went off since we left,” pilot Lenkei suggested. “It’s been centuries on Earth. I imagine they’re doing marvelous things.”

“Not dispatching probes to the core, surely,” cosmologist Chidambaran objected. “Thirty millennia to get there, and as much to flash a message back? It does not make sense. I expect man will spread slowly inward, colony by colony.”

“Failing a faster-than-light drive,” Lenkei said.

Chidambaran’s swarthy features and small-boned body came as near registering scorn as had ever been seen on him. “That fantasy! If you want to rewrite everything we have learned since Einstein— no, since Aristotle, considering the logical contradiction involved in a signal without a limiting velocity— proceed.”

“Not my line of work.” Lenkei’s greyhound slenderness seemed abruptly haggard. “I don’t want faster-than-light, anyhow. The idea that others might be speeding from star to star like birds— like me from town to town when I was home— while we’re caged here… that would be too cruel.”

“Our fate would not be changed by their fortune,” Chidambaran replied. “Indeed, irony would add another dimension to it, another challenge if you will.”

“I’ve more challenge than I want,” Lenkei said.

Their footfalls resounded on the winding stairs and up the well. They had come together from a low-level shop where Nilsson had been consulting Foxe-Jameson and Chidambaran about the design of a large crystal diffraction grating.

“It’s easier for you,” exploded from the pilot. “You’ve got a real use. We depend on your team. If you can’t produce new instruments for us— Me, till we reach a planet where they need space ferries and aircraft, what am I?”

“You are helping build those instruments, or will be when we have plans drawn up,” Chidambaran said.

“Yes, I apprenticed myself to Sadek. To pass this bloody empty time.” Lenkei collected his wits. “I’m sorry. An attitude we’ve get to steer clear of, I know. Mohandas, may I ask you something?”

“Certainly.”

“Why did you sign on? You’re important today. But if we hadn’t had the accident— couldn’t you have gone further toward understanding the universe back on Earth? You’re a theoretician, I’m told. Why not leave the fact gathering to men like Nilsson?”

“I would scarcely have lived to do much with reports from Beta Virginis. It seemed of possible value that a scientist of my sort expose himself to wholly new experiences and impressions. I might have gained insights that would never come otherwise. If I didn’t, the loss would not be large, and at a minimum I would have continued thinking approximately as well as at home.”

Lenkei tugged his chin. “Do you know,” he said, “I suspect you don’t need dream-box sessions.”

“It may be. I confess I find the process undignified.”

“Then for heaven’s sake, why?”

“Regulations. We must all receive the treatment. I did request exemption. Constable Reymont persuaded First Officer Lindgren that special privilege, albeit justified, would set a bad precedent.”

“Reymont! That bastard again!”

“He may be correct,” Chidambaran said. “It does me no harm, unless one counts the interruption of a train of thought, and that happens too seldom to be a major handicap.”
