СКАЧАТЬ gap between his own time and culture and this one that he’d yet encountered.

      Humankind had been working with direct man-machine neural interfaces for the major part of the species’ technic history—nineteen hundred years at least—and with various forms of artificial intelligence for longer than that. Implant technology had begun as crude molecular arrays of 2K protein processor nodes that facilitated direct downloads of data from primitive computer nets. Eventually, those early implants had evolved into nanochelated structures of complex design, organic-machine hybrids residing within the brain and running an enormous variety of software that usually included a resident personal AI. These personal secretaries or “essistants” could so perfectly mimic their fully organic host that it was possible to hold a conversation with one on any topic and be unaware that you were speaking with a machine—the final evocation of the ancient proposal known as the Turing Test.

      Such essistants were considered vital in modern communications and interface technologies, and more and more interactions with machines, from accessing research data banks or piloting spacecraft to growing furniture or opening doors or turning on a room’s illumination system, required an implant.

      Which left people without implants, the Disimplanteds, or “Disimps,” out in the cold and dark, often literally.

      But the AIs of Garroway’s day had been designed to pick up only on those thoughts that were appropriately coded, preceded by a mental symbol that told the AI that it was welcome. The idea of allowing any intelligence, even a manmade one, into his thoughts without permission was profoundly disturbing.

      And allowing machines to read minds for purposes of “social control” was, to Garroway’s way of thinking, horrifying. Did that mean they had artificial intelligences prowling the streets of human worlds and habs, listening for stray thoughts that might lead to social unrest, crime, or dissidence?

      And how did you tell the difference between an artificial intelligence and a member of that new species Schilling had mentioned … what had she called them? The Homo telae? Could they read minds as well?

      “I don’t think I like this full-access idea,” he told them.

      “I don’t imagine you do,” Schilling said. “It probably feels pretty strange … even creepy. It’s not a bad thing, however. Crime—at least outside of the free zones—is almost unknown. Intraspecies war—both civil war and war between separate human governments or religious groups—is all but obsolete. Humankind has never known such an era of peace and general well-being.”

      “So what do the AIs do in this utopia of yours?” Garroway said. “Eavesdrop on street corners, and call the cops when they hear the random, disgruntled rant against the government?”

      “Not ‘cops,’?” Socrates told him. “That’s antiquated terminology. We refer to socons. Agents of social control.”

      “This is sounding worse and worse.”

      “Most socons are AIs,” Schilling said. “Though there are human agents, of course. In most cases, they can correct aberrant behavior directly and immediately, and the person involved—whether he’s a criminal, a political dissident, or mentally ill—can be adjusted, healed … and never even know the adjustment has taken place.”

      “Captain,” he replied slowly, “you are scaring the hell out of me. Who decides what is dissident, and what is just an expression of a less-than-mainstream opinion? Who determines what mentally ill is? What are the standards? It’s not like you can diagnose mental illness by pulling a throat culture, damn it!”

      “Gently, General,” Socrates told him. “It’s not as bad as you think. Our system has worked, and worked well, for over five centuries.”

      Garroway started to reply, then thought better of it. Until he had a better feel for this culture, and for its rules and regulations both written and unwritten, he was going to need to keep his mouth shut and his eyes, ears, and implant open. Something he said now, in ignorance, might well prejudice these people against both him and his own Marines.

      “I’ll take your word for it,” he said, but his reservations remained. “You were telling me, though, about alien intelligences inhabiting stars.”

      “Indeed. They seem to be relatively rare, but several species, existing as coherent plasmas, have evolved within stellar atmospheres, or, in two cases of which we know, deep within the stellar core. Obviously, our communications with such beings are somewhat … limited.”

      The view of the Core Detonation had continued to grow and change as they talked. The scene now appeared to be centered on a glowing disk, a pinwheel of light shading from red at the outer rim to an intense, eye-watering violet at the center.

      “Is that the Galactic Core?” Garroway asked. The pinwheel, obviously, was an accretion disk. At its center was a tiny void, an emptiness, into which compressed gas and stellar material appeared to be funneling, a large and massive black hole. Dying matter shrieked its death scream in X-rays and the far ultraviolet.

      “No,” Socrates told him. “The Core is about 350 light years in that direction.” Garroway sensed the gesture, deeper into an impenetrable haze of blue-white radiance beyond. “This is the Great Annihilator.”

      Garroway had heard of it. A black hole, yes … but not, as once had been imagined, the supermassive black hole at the Galaxy’s exact center. The true Galactic Core consisted of a black hole of about two million solar masses, but, until the Core Detonation wavefront reached the vicinity of Earth, there would be no physical evidence pinpointing it from Earth’s vicinity save for the observed movements of core stars, no light, no radiation of any sort.

      The Great Annihilator, on the other hand, was a black hole of only about fifteen solar masses, but it was far noisier—as heard from Earth, at any rate—than its far larger brother nearby. Twin shafts of high-energy radiation speared in opposite directions from the poles of its central hub, streams of positrons emerging from the turbulent areas above the black hole’s north and south poles. The interaction of antimatter with normal matter hundreds of light years from the singularity filled the Core with radio noise—the 511?keV screech of positronium annihilating its normal-matter counterpart—electrons. The object had been detected and named “The Great Annihilator” by Earth astronomers millennia ago, but the discovery had only deepened the mystery of the actual nature of the Galactic Core. By measuring the velocities of stars in the Annihilator’s immediate vicinity, astronomers had proven that it was a black hole, but not the far more massive one at the exact center that they’d been looking for.

      In Garroway’s day, of course, it had been well understood that the Xul Dyson cloud had been masking the radiation leakage from the actual Core, and would continue to do so until the Core Detonation crawled out into the Galactic suburbs and impinged upon waiting detectors and sense organs. The Great Annihilator, though, had become a footnote to Galactic cosmography, a little-brother satellite of the larger, better known singularity at GalCenter.

      The Core Detonation would have swallowed the Great Annihilator centuries ago. Evidently, the object had not been destroyed, as might have been expected. Clouds of dust and gas sweeping out from the Core explosions had spiraled into the Annihilator’s accretion disk, which glowed now as brightly as a supernova. So much matter continued to fall into the singularity itself that vast quantities, instead of being swallowed, were flung outward as radiant plasmas, and the radio shriek of annihilating matter was far louder now than it had been twelve hundred years before. Garroway could hear that shriek overlaid upon the visual image. Inset windows gave scrolling blocks of data describing СКАЧАТЬ
