Tau Zero

She matched him drink for drink, though she had less mass and less practice. The meal that followed was lengthy even by Scandinavian standards, with considerable wine during it and considerable cognac afterward. He let her do most of the talking.

— of a house near Drottningholm, whose park and gardens were almost her own; sunlight through windows, gleaming over burnished wood floors and on silver that had been passed down for ten generations; a sloop on the lake, heeled to the wind, her father at the tiller with a pipe in his teeth, her hair blowing loose; monstrous nights at wintertime, and in their middle that warm cave named Christmas; the short light nights of summer, the balefires kindled on St. John’s Eve that had once been lit to welcome Baldr home from the underworld; a walk in the rain with a first sweetheart, the air cool, drenched with water and odor of lilacs; travels around Earth, the Pyramids, the Parthenon, Paris at sunset from the top of Montparnasse, the Taj Mahal, Angkor Wat, the Kremlin, the Golden Gate Bridge, yes, and Fujiyama, the Grand Canyon, Victoria Falls, the Great Barrier Reef—

— of love and merriment at home but discipline too, order, gravity in the presence of strangers; music around, Mozart the dearest; a fine school, where teachers and classmates brought a complete new universe exploding into her awareness; the Academy, harder work than she had known she could do, and how pleased she was to discover she was able; cruises through space, to the planets, oh, she had stood on the snows of Titan with Saturn overhead, stu

— in a good world, its people, their doings, their pleasures all good; yes, there remained problems, outright cruelties, but those could be solved in time through reason and good will; it would be a joy to believe in some kind of religion, since that would perfect the world by giving it ultimate purpose, but in the absence of convincing proof she could still do her best to help supply that meaning, help mankind move toward something loftier—

— but no, she wasn’t a prig, he mustn’t believe that; in fact, she often wondered if she wasn’t too hedonistic, a bit more liberated than was best; however, she did get fun out of life without hurting anyone else, as far as she could tell; she lived with high hopes.

Reymont poured the last coffee for her. The waiter had finally brought the bill, though he seemed in no more hurry to collect than most of his kind in Stockholm. “I except that in spite of the drawbacks,” Reynont said, “you’ll manage to enjoy our voyage.”

Her voice had gotten a bit slurred. Her eyes, regarding him, stayed bright and level. “I plan to,” she declared, “That’s the main reason I called you. Remember, during training I urged you to come here for part of your furlough.” By now they were using the intimate pronoun.

Reymont drew on his cigar. Smoking would be prohibited in space, to avoid overloading the life support systems, but tonight he could still put a blue cloud in front of him.

She leaned forward, laying a hand over his free one on the table. “I was thinking ahead,” she told him. “Twenty-five men and twenty-five women. Five years in a metal shell. Another five years if we turn back immediately. Even with antisenescence treatments, a decade is a big piece out of a life.”

He nodded.

“And of course we’ll stay to explore,” she went on. “If that third planet is habitable, we’ll stay to colonize — forever — and we’ll start having children. Whatever we do, there are going to be liaisons. We’ll pair off.”

He said, low lest it seem too blunt: “You think you and I might make a couple?”

“Yes.” Her tone strengthened. “It may seem immodest of me, whether or not I am a spacewoman. But I’ll be busier than most, the first several weeks of travel especially. I won’t have time for nuances and rituals. It could end with me in a situation I don’t want. Unless I think ahead and make preparations. As I’m doing.”

He lifted her hand to his lips. “I am deeply honored, Ingrid. Though we may be too unlike.”

“No, I suspect that’s what draws me.” Her palm curved around his mouth and slid down his cheek. “I want to know you. You are more a man than any I’ve met before.”

He counted money onto the bill. It was the first time that she had seen him move not entirely steadily. He ground out his cigar, watching it as he did. “I’m staying at a hotel over on Tyska Brinken,” he said. “Rather shabby.”

“I don’t mind,” she answered. “I doubt if I’ll notice.”

Chapter 2

Seen from one of the shuttles that brought her crew to her, Leonora Christine resembled a dagger pointed at the stars.

Her hull was a conoid, tapering toward the bow. Its burnished smoothness seemed ornamented rather than broken by the exterior fittings. These were locks and hatches; sensors for instruments; housings for the two boats that would make the planetfalls for which she herself was not designed; and the web of the Bussard drive, now folded flat. The base of the conoid was quite broad, since it contained the reaction mass among other things; but the length was too great for this to be particularly noticeable.

At the top of the dagger blade, a structure fa

Beyond this, darker in hue, extended the haft of the dagger, ending finally in an intricate pommel. The latter was the Bussard engine; the rest was shielding against its radiation when it should be activated.

Thus Leonora Christine, seventh, and youngest of her class. Her outward simplicity was required by the nature of her mission and was as deceptive as a human skin; inside, she was very nearly as complex and subtle. The time since the basic idea of her was first conceived, in the middle twentieth century, had included perhaps a million man-years of thought and work directed toward achieving the reality; and some of those men had possessed intellects equal to any that had ever existed. Though practical experience and essential tools had already been gotten when construction was begun upon her, and though technological civilization had reached its fantastic flowering (and finally, for a while, was not burdened by war or the threat of war) — nevertheless, her cost was by no means negligible, had indeed provoked widespread complaint. All this, to send fifty people to one practically next-door star?

Right. That’s the size of the universe.

It loomed behind her, around her, where she circled Earth. Staring away from sun and planet, you saw a crystal darkness huger than you dared comprehend. It did not appear totally black; there were light reflections within your eyeballs, if nowhere else; but it was the final night, that our kindly sky holds from us. The stars thronged it, unwinking, their brilliance winter-cold. Those sufficiently luminous to be seen from the ground showed their colors clear in space: steel-blue Vega, golden Capella, ember of Betelgeuse. And if you were not trained, the lesser members of the galaxy that had become visible were so many as to drown the familiar constellations. The night was wild with suns.

And the Milky Way belted heaven with ice and silver; and the Magellanic Clouds were not vague shimmers but roiling and glowing; and the Andromeda galaxy gleamed sharp across more than a million light-years; and you felt your soul drowning in those depths and hastily pulled your vision back to the snug cabin that held you.

Ingrid Lindgren entered the bridge, caught a handhold, and poised in mid-air. “Reporting for duty, Mr. Captain,” she a
