"Permit me to present an example. If the barytrine field went on at this instant, one thousand years from now my successor would pick up the thread of the conversation from the recording we are making, and take on from here. As far as you are concerned the only difference would be a sudden flick of the viewscreen and a rather abrupt change in the facial characteristics of your conferee." Gant Nerley waited a moment to let the point sink in. "Now, since you and I have very little in common, it should make little difference to you whether you spoke to me or to someone else. And as far as I am concerned, I feel the same. I have long since ceased feeling regretful that I cannot retain friendship with the hundreds of thousands of people with whom I must converse. I have almost stopped being regretful of the fact that there are so many worlds that no single lifetime would permit a visit to more than a fraction. I suggest that you try to take a more lasting attitude. You sound as though the troubles of a world you never saw were of prime importance to you."
"Look," said Dusty testily, "A lot of what you claim may be true. But we have a couple of thousand years of observational data on the planets and the nearby stars. You may take a thousand years out of our lives in the twinkle of a second, but then we spend another five hundred on top of that finding out where we are."
"You have time."
"We have not!" roared Dusty. "Move us to a new system and I'll tell you what'll happen. Before we can make a move into space we have to chart the new system completely, because we admit that our reaction motors are not efficient enough to take off without a well precharted course. We must know the orbits of the planets to a fine degree before we dare. Then, before we can make a try for the stars, we've got to spend years and years in observation before we can chart the nearest stars and observe whether or not they might have planets, our astronomy will be put back. Now—"
"Pardon me, but the information I have regarding your system is before me. Your space travel is primitive and any form of real commerce is as yet impossible. This I get from the license application for barytrine operations. Now, how can you justify your statements about interstellar travel?"
Dusty Britton, no matter what else, was a good actor any time he could sit in with a large Virginia Ham to carve. Dusty would never play Hamlet or Julius Caesar; a custard pie in the face was closer to Dusty's art than John Barrymore. This fact provided for Dusty a rather interesting background for the present argument. A student of science could not have faced Gant Nerley without paying deference to the Marandanian's obviously superior knowledge, position and experience. The learned man makes no flat-footed statements; this leads to the odd belief that most learned men are not entirely sure of themselves. It is the bird who is ignorant of all the myriad things that he does not know that can afford to stand up on his hind feet and reel off chapter and verse as though there could be no rebuttal.
So Dusty Britton, who could portray a reasonably convincing role of a wounded hero while mentally contemplating how long it would be before the first preprandial martini, plus being the flamboyant type who never lets a few facts stop his flow of words, was not abashed to let on that he knew a lot more than the Marandanian suspected. Furthermore, Dusty felt that he had Gant Nerley on the defensive, and if he could put the Marandanian off balance long enough to accomplish something, Dusty did not care if Nerley accused him of being a four-flusher at some later date.
Keeping this in mind, Dusty braced himself with little effort and tried to reduce to bafflegab what he recalled of Scyth Radnor's previous statements.
"Interstellar travel is, of course, based upon obvious errors in the theoretical mathematics of general relativity," said Dusty, as though he were reciting some of the science-double-talk usually included in Dusty Britton And The Space Patrol. "Of the many schools of thought which have their own theories on how to explain these obvious errors, the group-velocity field seems to be the most successful. But all of them are seeking some evidence to support their theories, and a couple of them, namely the gravitic and the magnetic-field proponents claim that such evidence has already supported their claim. Now, if such is the case, you know it will not be long before some practical experiment will disprove the illogic of providing a finite limit to an infinite system. Once this has been established it seems obvious that star-travel is the next step."
