Cities in Flight

that I’m quizzing you, by the way. You’re at perfect liberty to say that any given question is none of my business, and I’ll take no offense and hold no grudge. Also, ‘I hereby disavow the authenticity of any tape or other tapping of which this statement may be a part.’ In short, our conversation is unofficial, highly so.”

“Thank you.”

“It’s to my interest; I’m hoping that you’ll talk freely to me. Of course, my disavowal means nothing, since such formal statements can always be excised from a tape; but later on I’m going to tell you some things you’re not supposed to know, and you’ll be able to judge by what I say that anything you say to me is privileged. Paige and Anne are your witnesses. Okay?”

A steward came in silently with the drinks and left again. Helmuth tasted his. As far as he could tell, it was exactly like many he had mixed for himself back in the control shack from standard space rations. The only difference was that it was cold, which Helmuth found startling but not unpleasant after the first sip. He tried to relax. “I’ll do my best,” he said.

“Good enough. Now: Dillon says that you regard the Bridge as a monster. I’ve examined your dossier pretty closely—as a matter of fact I’ve been studying both you and Paige far more intensively than you can imagine—and I think perhaps Dillon hasn’t quite the gist of your meaning. I’d like to hear it straight from you.”

“I don’t think the Bridge is a monster,” Helmuth said slowly. “You see, Charity is on the defensive. He takes the Bridge to be conclusive evidence that no possible set of adverse conditions will ever stop man for long, and there I’m in agreement with him. But he also thinks of it as Progress, personified. He can’t admit—you asked me to speak my mind, Senator—he can’t admit that the West is a decadent and dying culture. All the other evidence that’s available shows that it is. Charity likes to think of the Bridge as giving the lie to that evidence.”

“The West hasn’t many more years,” Wagoner agreed, astonishingly.

Paige Russell mopped his forehead. “I still can’t hear you say that,” the spaceman said, “without wanting to duck under the rug. After all, MacHinery’s with that pack on Ganymede—”

“MacHinery,” Wagoner said calmly, “is probably going to die of apoplexy when we spring this thing on him, and I for one won’t miss him. Anyhow, it’s perfectly true; the dominoes have been falling for some time now, and the explosion Anne’s outfit has cooked up is going to be the final blow. Still and all, Mr. Helmuth, the West has been responsible for some really towering achievements in time. Perhaps the Bridge could be considered as the last and mightiest of them all.”

“Not by me,” Helmuth said. “The building of gigantic projects for ritual purposes—doing a thing for the sake of doing it—is the last act of an already dead culture. Look at the pyramids in Egypt for an example. Or at an even more enormous and more idiotic example, bigger than anything human beings have accomplished yet—the laying out of the ‘Diagram of Power’ over the whole face of Mars. If the Martians had put all that energy into survival instead, they’d probably be alive yet.”

“Agreed,” Wagoner said, “with reservations. You’re right about Mars, but the pyramids were built during the springtime of the Egyptian culture. And ‘doing a thing for the sake of doing it’ is not a definition of ritual; it’s a definition of science.”

“All right. That doesn’t greatly alter my argument. Maybe you’ll also agree that the essence of a vital culture is its ability to defend itself. The West has beaten the Soviets for half a century now—but as far as I can see, the Bridge is the West’s ‘Diagram of Power,’ its pyramids, or what have you. It shows that we’re mighty, but mighty in a non-survival sort of way. All the money and the resources that went into the Bridge are going to be badly needed, and won’t be there, when the next Soviet attack comes.”

“Correction: it has already come,” Wagoner said. “And it has already won. The USSR played the greatest of all von Neumann games far better than we did, because they didn’t assume as we did that each side would always choose the best strategy; they played also to wear down the players. In fifty years of unrelenting pressure, they succeeded in converting the West into a system so like the Soviets’ as to make direct military action unnecessary; we Sovietized ourselves, and our moves are now exactly predictable.

“So in part I agree with you. What we needed was to sink the energy and the money into the game—into social research, since the menace was social. Instead, typically, we put it into a physical research project of unprecedented size. Which was, of course, just what the theory of games said we would do. For a man who’s been cut off from Earth for years, Helmuth, you seem to know more about what’s going on down there than most of the general populace does.”

“Nothing promotes an interest in Earth like being off it,” Helmuth said. “And there’s plenty of time to read out here.” Either the drink was stronger than he had expected—which was reasonable, considering that he had been off the stuff for some time now—or the senator’s calm concurrence in the collapse of Helmuth’s entire world had given him another shove toward the abyss; his head was spinning.

Wagoner saw it. He leaned forward suddenly, catching Helmuth flat-footed. “However,” he said, “it’s difficult for me to agree that the Bridge serves, or ever did serve, a ritual purpose. The Bridge served several huge practical purposes which are now fulfilled. As a matter of fact, the Bridge, as such, is now a defunct project.”

“Defunct?” Helmuth said faintly.

“Quite. Of course, we’ll continue to operate it for a while. You can’t stop a process of that size on a dime. Besides, one of the reasons why we built the Bridge was because the USSR expected us to; the game said that we should launch another Manhattan District or Project Lincoln at this point, and we hated to disappoint them. One thing we are not going to do this time, however, is to tell them the problem that the project was supposed to solve—let alone that it can be solved, and has been.

“So we’ll keep the Bridge going, physically and publicly. That’ll be just as well, too, for people like Dillon who are emotionally tied up in it, above and beyond their conditioning to it. You’re the only person in authority in the whole station who’s already lost enough interest in the Bridge to make it safe for me to tell you that it’s being abandoned.”

“But why?”

“Because,” Wagoner went on quietly, “the Bridge has now given us confirmation of a theory of stupendous importance—so important, in my opinion, that the imminent fall of the West seems like a puny event in comparison. A confirmation, incidentally, which contains in it the seeds of ultimate destruction for the Soviets, whatever they may win for themselves in the next hundred years or so.”

“I suppose,” Helmuth said, puzzled, “that you mean antigravity?”

For the first time, it was Wagoner’s turn to be taken aback. “Man,” he said at last, “do you know everything I want to tell you? I hope not, or my conclusions will be mighty unwelcome to both of us. Do you also know what an anti-agathic is?”

“No,” Helmuth said. “I don’t even recognize the root of the word.”

“Well, that’s a relief. But surely Charity didn’t tell you we had antigravity. I strictly enjoined him not to mention it.”

“No. The subject’s been on my mind,” Helmuth said. “But I certainly don’t see why it should be so world- shaking, any more than I see how the Bridge helped to bring it about. I thought it would be developed independently, for the further exploitation of the Bridge. In other words, to put men down there, and short-circuit this remote control operation we have on Jupiter V. And I thought it would step up Bridge operation, not discontinue it.”

“Not at all. Nobody in his right mind would want to put men on Jupiter, and besides, gravity isn’t the main problem down there. Even eight gravities is perfectly tolerable for short periods of time—and anyhow a man in a pressure suit couldn’t get five hundred miles down through that atmosphere before he’d be as buoyed up and weightless as a fish—and even more thoroughly at the mercy of the currents.”

“And you can’t screen out the pressure?”

“We can,” Wagoner said, “but only at ruinous cost. Besides, there’d be no point in trying. The Bridge is finished. It’s given us information in thousands of different categories, much of it very valuable indeed. But the one job that only the Bridge could do was that of confirming, or throwing out, the Blackett-Dirac equations.”

“Which are—?”

“They show a relationship between magnetism and the spinning of a massive body—that much is the Dirac part of it. The Blackett Equation seemed to show that the same formula also applied to gravity; it says G equals (2CP/BU ² ), where C is the velocity of light, Pis magnetic moment, and U is angular momentum. B is
