"Space is curved in the fourth dimension, and fifth-order rays, with their velocity, may not follow the same path in that dimension that light does—in fact, they do not. If that path is to be plotted it requires the solution of five simultaneous equations, each complete and general, and each of the fifth degree, and also an exponential series with the unknown in the final exponent, before the fourth-dimensional concept can be derived ... hm—m—m. No use—we've struck something that not even Norlaminian theory can handle."
"You surprise me." Crane said. "I supposed that they had everything worked out."
"Not on fifth-order stuff—it's new, you know. It begins to look as though we'd have to stick around until every one of those torpedoes gets somewhere near its mother-ship. Hate to do it, too—it'll take six months, at least, to reach the vessels clear across the Galaxy. I'll put it up to the gang at dinner—guess they'll let me talk business a couple of minutes overtime, especially after they find out what I've got to say."
He explained the phenomenon to an interested group of white-bearded scientists as they ate. Rovol, to Seaton's surprise, was elated and enthusiastic.
"Wonderful, my boy!" he breathed. "Marvelous! A perfect subject for years after year of deepest study and the most profound thought. Perfect!"
"But what can we do about it?" asked Seaton, exasperated. "We don't want to hang around here twiddling our thumbs for a year waiting for those torpedoes to get to wherever they're going!"
"We can do nothing but wait and study. That problem is one of splendid difficulty, as you yourself realize. Its solution may well be a matter of lifetimes instead of years. But what is a year, more or less? You can destroy the Fenachrone eventually, so be content."
"But content is just exactly what I'm not!" declared Seaton, emphatically. "I want to do it, and do it now!"
"Perhaps I might volunteer a suggestion," said Caslor, diffidently; and as both Rovol and Seaton looked at him in surprise he went on: "Do not misunderstand me. I do not mean concerning the mathematical problem in discussion, about which I am entirely ignorant. But has it occurred to you that those torpedoes are not intelligent entities, acting upon their own volition and steering themselves as a result of their own ordered mental processes? No, they are mechanisms, in my own province, and I venture to say with the utmost confidence that they are guided to their destinations by streamers of force of some nature, emanating from the vessels upon whose tracks they are."
"'Nobody Holme' is right!" exclaimed Seaton, tapping his temple with an admonitory forefinger. "'Sright, ace—I thought maybe I'd quit using my head for nothing but a hatrack now, but I guess that's all it's good for, yet. Thanks a lot for the idea—that gives me something I can get my teeth into, and now that Rovol's got a problem to work on for the next century or so, everybody's happy."
