Brian Taggert was an analyzer, an originator, a motivator—and more. The young man found himself avoiding too deep a probe into the mind of Brian Taggert; he knew that he had not yet achieved the maturity to understand the multilayered depths of a mind like that. Eventually, perhaps....

Not that Senator Gonzales was a child, nor that he was emotionally or intellectually shallow. It was merely that he was not of Taggert's caliber.

The young man absently took another drag from his cigarette. Taggert had explained the basic problem to him, but he was getting a wider picture from the additional information that Senator Gonzales had brought.

Dr. Theodore Nordred, a mathematical physicist and one of the top-flight, high-powered, original minds in the field, had shown that Einstein's final equations only held in a universe composed entirely of normal matter. Since the great Einstein had died before the Principle of Parity had been overthrown in the mid-fifties, he had been unable to incorporate the information into his Unified Field Theory. Nordred had been able to show, mathematically, that Einstein's equations were valid only for a completely "dexter," or right-handed universe, or for a completely "sinister" or left-handed universe.

Although the universe in which Man lived was predominantly dexter—arbitrarily so designated—it was not completely so. It had a "sinister" component amounting to approximately one one-hundred-thousandth of one per cent. On the average, one atom out of every ten million in the universe was an atom of antimatter. The distribution was unequal of course; antimatter could not exist in contact with ordinary matter. Most of it was distributed throughout interstellar space in the form of individual atoms, freely floating in space, a long way from any large mass of normal matter.

But that minute fraction of a per cent was enough to show that the known universe was not totally Einsteinian. In a purely Einsteinian universe, antigravity was impossible, but if the equations of Dr. Theodore Nordred were actually a closer approximation to true reality than those of Einstein, then antigravity might be a practical reality.

And that was the problem the Redford Research Team was working on. It was a parallel project to the interstellar drive problem, being carried on elsewhere.


The "pet spy," as Taggert had called him, was Dr. Konrad Bern, a middle-aged Negro from Tanganyika, who was convinced that only under Communism could the colored races of the world achieve the technological organization and living standard of the white man. He had been trained as a "sleeper"; not even the exhaustive investigations of the FBI had turned up any relationship between Bern and the Soviets. It had taken the telepathic probing of the S.M.M.R. agents to uncover his real purposes. Known, he constituted no danger.

There was no denying that he was a highly competent, if not brilliant, physicist. And, since it was quite impossible for him to get any information on the Redford Project into the hands of the opposition—it was no longer fashionable to call Communists "the enemy"—there was no reason why he shouldn't be allowed to contribute to the American efforts to bridge space.
