She was a wonder junkie. In her mind, she was a hill tribesman standing slack-jawed before the real Ishtar Gate of ancient Babylon; Dorothy catching her first glimpse of the vaulted spires of the Emerald City of Oz; a small boy from darkest Brooklyn plunked down in the Corridor of Nations of the 1939 World’s Fair, the Trylon and Perisphere beckoning in the distance; she was Pocahontas sailing up the Thames estuary with London spread out before her from horizon to horizon.
Her heart sang in anticipation. She would discover, she was sure, what else is possible, what could be accomplished by other beings, great beings–beings who had, it seemed likely, been voyaging between the stars when the ancestors of humans were still brachiating from branch to branch in the dappled sunlight of the forest canopy.
Drumlin, like many others she had known over the years, had called her an incurable romantic; and she found herself wondering again why so many people thought it some embarrassing disability. Her romanticism had been a driving force in her life and a fount of delights. Advocate and practitioner of romance, she was off to see the Wizard.
A status report came through by radio. There were no apparent malfunctions, so far as could be detected with the battery of instrumentation that had been set up exterior to the Machine. Their main wait was for the evacuation of the space between and around the benzels. A system of extraordinary efficiency was pumping out the air to attain the highest vacuum ever reached on Earth. She double-checked the stowage of her video microcamera system and gave the palm frond a pat. Powerful lights on the exterior of the dodecahedron had turned on. Two of the spherical shells had now spun up to what the Message had defined as critical speed. They were already a blur to those watching outside. The third benzel would be there in a minute. A strong electrical charge was building up. When all three spherical shells with their mutually perpendicular axes were up to speed, the Machine would be activated. Or so the Message had said.
Xi’s face showed fierce determination, she thought; Lunacharsky’s a deliberate calm; Sukhavati’s eyes were open wide; Eda revealed only an attitude of quiet attentiveness. Devi caught her glance and smiled. She wished she had had a child. It was her last thought before the walls flickered and became transparent and, it seemed, the Earth opened up and swallowed her.

CHAPTER 19
Naked Singularity
…mount to paradise By the stairway of surprise.
– RALPH WALDO EMERSON
“Merlin,” Poems (1847)
It is not impossible that to some infinitely superior being the whole universe may be as one plain, the distance between planet and planet being `only as the pores in a grain of sand, and the spaces between system and system no greater than the intervals between one grain and the grain adjacent.

THEY WERE falling. The pentagonal panels of the dodecahedron had become transparent. So had the roof and the floor. Above and below she could make out the organosilicate lacework and the implanted erbium dowels, which seemed to be stirring. All three benzels had disappeared. The dodecahedron plunged, racing down a long dark tunnel just broad enough to permit its passage. The acceleration seemed somewhere around one g. As a result, Ellic, facing forward, was pressed backward in her chair, while Devi, opposite her, was bending slightly at the waist. Perhaps they should have added seat belts.
It was hard not to entertain the thought that they had plunged into the mantle of the Earth, bound for its core of molten iron. Or maybe they were on their way straight to…She tried to imagine this improbable conveyance as a ferryboat upon the River Styx.
There was a texture to the tunnel walls, from which she could sense their speed. The patterns were irregular soft-edged mottlings, nothing with a well-defined form. The walls were not memorable for their appearance, only for their function. Even a few hundred kilometers beneath the Earth’s surface the rocks would be glowing with red heat. There was no hint of that. No minor demons were managing the traffic, and no cupboards with jars of marmalade were in evidence.
Every now and then a forward vertex of the dodecahedron would brush the wall, and flakes of an unknown material would be scraped off. The dodec itself seemed unaffected. Soon, quite a cloud of fine particles was following them. Every time the dodecahedron touched the wall, she could sense an undulation, as if something soft had retreated to lessen the impact. The faint yellow lighting was diffuse, uniform. Occasionally the tunnel would swerve gently, and the dodec would obligingly follow the curvature. Nothing, so far as she could see, was headed towardthem. At these speeds, even a collision with a sparrow would produce a devastating explosion. Or what if this was an endless fall into a bottomless well? She could feel a continuous physical anxiety in the pit of her stomach. Even so, she entertained no second thoughts.
Black hole, she thought. Black hole. I’m falling through the event horizon of a black hole toward the dread singularity. Or maybe this isn’t a black hole and I’m headed toward a naked singularity. That’s what the physicists called it, a naked singularity. Near a singularity, causality could be violated, effects could precede causes, time could flow backward, and you were unlikely to survive, much less remember the experience. For a rotating black hole, she dredged up from her studies years before, there was not a point but a ring singularity or something still more complex to be avoided. Black holes were nasty. The gravitational tidal forces were so great that you would be stretched into a long thin thread if you were so careless as to fall in. You would also be crushed laterally. Happily, there was no sign of any of this. Through the gray transparent surfaces that were now the ceiling and floor, she could see a great flurry of activity. The organosilicate matrix was collapsing on itself in some places and unfolding in others; the embedded erbium dowels were spinning and tumbling. Everything inside the dodec–including herself and her companions– looked quite ordinary. Well, maybe a bit excited. But they were not yet long thin threads.
These were idle ruminations, she knew. The physics of black holes was not her field. Anyway, she could not understand how this could have anything to do with black holes, which were either primordial–made during the origin of the universe–or produced in a later epoch by the collapse of a star more massive than the Sun. Then, the gravity would be so strong that–except for quantum effects–even light could not escape, although the gravitational field certainly would remain. Hence “black,” hence “hole.” But they hadn’t `collapsed a star, and she couldn’t see any way in which they had captured a primordial blackhole. Anyway, no one knew where the nearest primordial black hole might be hiding. They had only built the Machine and spun up the benzels.
She glanced over to Eda, who was figuring something on a small computer. By bone conduction, she could feel as well as hear a low-pitched roaring every time the dodec scraped the wall, and she raised her voice to be heard. “Do you understand what’s going on?”
“Not at all,” he shouted back. “I can almost prove this can’t be happening. Do you know the Boyer- Lindquist coordinates?”
“No, sorry.” “I’ll explain it to you later.” She was glad he thought there would be a “later.” Ellie felt the deceleration before she could see it, as if they had been on the downslope of a roller coaster, had leveled out, and now were slowly climbing. Just before the deceleration set in, the tunnel had made a complex sequence of bobs and weaves. There was no perceptible change either in the color or in the brightness of the surrounding light. She picked up her camera, switched to the long-focal-length lens, and looked as far ahead of her as she could. She could see only to the next jag in the tortuous path. Magnified, the texture of the wall seemed intricate, irregular, and, just for a moment, faintly self-luminous.
The dodecahedron had slowed to a comparative crawl. No end to the tunnel was in sight. She wondered if they would make it to wherever they were going. Perhaps the designers had miscalculated. Maybe the Machine had been built imperfectly, just a little bit off; perhaps what had seemed on Hokkaido an acceptable technological imperfection would doom their mission to failure here in…in wherever this was. Or, glancing at the cloud of fine particles following and occasionally overtaking them, she thought maybe they had bumped into the walls one time too often and lost more momentum than had been allowed for in the design. The space between the dodec and the walls seemed very narrow now. Perhaps they would find themselves stuck fast in this never-never land and languish until the oxygen ran out. Could the Vegans have gone to all this trouble and forgotten that we need to breathe? Hadn’t they noticed all those shouting Nazis? Vaygay and Eda were deep in the arcana of gravitational physics–twistors, renormalization of ghost propagators, time-like Killing vectors, non-Abelian gauge invariance, geodesic refocusing, eleven- dimensional Kaluza-Klein treatments of supergravity, and, of course, Eda’s own and quite different superunification. You could tell at a glance that an explanation was not readily within their grasp. She guessed that in another few hours the two physicists would make some progress on the problem. Superunification embraced virtually all scales and aspects of physics known on Earth. It was hard to believe that this…tunnel was not itself some hitherto unrealized solution of the Eda Field Equations.
