Robert Silverberg - Ship-Sister, Star-Sister

The year-captain whirls, seizes Noelle, pulls her against him. Feels her trembling. Comforts her, where a moment before she had been comforting him. Yes, yes, yes, yes, he murmurs. With his arm around her shoulders he turns, so that both of them are facing the viewplate. As if she could see. Nospace dances and churns an inch from his nose. He feels a hot wind blowing through the ship, the khamsin, the sirocco, the simoom, the leveche, a sultry wind, a killing wind coming out of the gray strangeness, and he forces himself not to fear that wind. It is a wind of life, he tells himself, a wind of joy, a cool sweet wind, the mistral, the tramontana. Why should he think there is anything to fear in the realm beyond the viewplate? How beautiful it is out there, how ecstatically beautiful! How sad that we can never tell anyone about it, now, except one another. A strange peace unexpectedly descends on him. Everything is going to be all right, he insists. No harm will come of what has happened. And perhaps some good. And perhaps some good. Benefits lurk in the darkest places.

She plays go obsessively, beating everyone. She seems to live in the lounge twenty hours a day. Sometimes she takes on two opponents at once—an incredible feat, considering that she must hold the constantly changing intricacies of both boards in her memory—and defeats them both: two days after losing verbal-level contact with Yvonne, she simultaneously triumphs over Roy and Heinz before an audience of thirty. She looks animated and buoyant; the sorrow she must feel over the snapping of the link she takes care to conceal. She expresses it, the others suspect, only by her manic go -playing. The year-captain is one of her most frequent adversaries, taking his turn at the board in the time he would have devoted to composing and dictating the communiques for Earth. He had thought go was over for him years ago, but he, too, is playing obsessively now, building walls and the unassailable fortresses known as eyes. There is reassurance in the rhythmic clacking march of the black and white stones. Noelle wins every game against him. She covers the board with eyes.

Who can explain the interference? No one believes that the problem is a function of anything so obvious as distance. Noelle has been quite convincing on that score: a signal that propagates perfectly for the first sixteen light-years of a journey ought not suddenly to deteriorate. There should at least have been prior sign of attenuation, and there was no attenuation, only noise interfering with and ultimately destroying the signal. Some force is intervening between the sisters. But what can it be? The idea that it is some physical effect analogous to sunspot static, that it is the product of radiation emitted by some giant star in whose vicinity they have lately been traveling, must in the end be rejected. There is no energy interface between realspace and nospace, no opportunity for any kind of electromagnetic intrusion. That much had been amply demonstrated long before any manned voyages were undertaken. The nospace tube is an impermeable wall. Nothing that has mass or charge can leap the barrier between the universe of accepted phenomena and the cocoon of nothingness that the ship’s drive mechanism has woven about them, nor can a photon get across, nor even a slippery neutrino.

Many speculations excite the voyagers. The one force that can cross the barrier, Roy points out, is thought: intangible, unmeasurable, limitless. What if the sector of realspace corresponding to this region of the nospace tube is inhabited by beings of powerful telepathic capacity whose transmissions, flooding out over a sphere with a radius of many light-years, are able to cross the barrier just as readily as those of Yvonne? The alien mental emanations, Roy supposes, are smothering the signal from Earth.

Heinz extends this theory into a different possibility: that the interference is caused by denizens of nospace. There is a seeming paradox in this, since it has been shown mathematically that the nospace tube must be wholly matter-free except for the ship that travels through it; otherwise a body moving at speeds faster than light would generate destructive resonances as its mass exceeds infinity. But perhaps the equations are imperfectly understood. Heinz imagines giant incorporeal beings as big as asteroids, as big as planets, masses of pure energy or even pure mental force that drift freely through the tube. These beings may be sources of bio-psychic transmissions that disrupt the Yvonne-Noelle circuit, or, maybe, they are actually feeding on the sisters’ mental output, Heinz postulates. “Angels,” he calls them. It is an implausible but striking concept that fascinates everyone for several days. Whether the “angels” live within the tube as proposed by Heinz, or on some world just outside it as pictured by Roy, is unimportant at the moment; the consensus aboard ship is that the interference is the work of an alien intelligence, and that arouses wonder in all.

What to do? Leon, inclining toward Roy’s hypothesis, moves that they leave nospace immediately and seek the world or worlds where the “angels” dwell. The year-captain objects, noting that the plan of the voyage obliges them to reach a distance of one hundred light-years from Earth before they begin their quest for habitable planets. Roy and Leon argue that the plan is merely a guide, arbitrarily conceived, and not received scriptural writ; they are free to depart from it if some pressing reason presents itself. Heinz, supporting the year-captain, remarks that there is no need actually to leave nospace regardless of the source of the alien transmissions; if the thoughts of these creatures can come in from beyond the tube, then Noelle’s thoughts can surely go outward through the tube to them, and contact can be established without the need of deviating from the plan. After all, if the interference is the work of beings sharing the tube with them, and the voyagers seek them in vain outside the tube, it may be impossible to find them again once the ship returns to nospace. This approach seems reasonable, and the question is put to Noelle: Can you attempt to open a dialogue with these beings?

She laughs. “I make no guarantees. I’ve never tried to talk to angels before. But I’ll try, my friends. I’ll try.”

She has never done anything like this before. It seems almost an act of infidelity, this opening of her mind to something or someone who is not Yvonne. But it must be done. She extends a tenuous tendril of thought that probes like a rivulet of quicksilver. Through the wall of the ship, into the surrounding grayness, upward, outward, toward, toward—

—angels?—

Angels. Oh. Brightness. Strength. Magnetism. Yes. Awareness now of a fierce roiling mass of concentrated energy close by. A mass in motion, laying a terrible stress on the fabric of the cosmos: the angel has angular momentum. It tumbles ponderously on its colossal axis. Who would have thought an angel could be so huge? Noelle is oppressed by the shifting weight of it as it makes its slow heavy axial swing. She moves closer. Oh. She is dazzled. Too much light! Too much power! She draws back, overwhelmed by the intensity of the other being’s output. Such a mighty mind: she feels dwarfed. If she touches it with her mind she will be destroyed. She must step down the aperture, establish some kind of transformer to shield herself against the full blast of power that comes from it. It requires time and discipline. She works steadily, making adjustments, mastering new techniques, discovering capacities she had not known she possessed. And now. Yes. Try again. Slowly, slowly, slowly, with utmost care. Outward goes the tendril.
