The gondola leaped wildly: a cable giving way. It almost pitched Corson overside, but the rope he had lashed around him saved his life. He caught a glimpse of the horizon, and uttered such a tremendous cry that for a brief moment it outdid the roaring of the wind.
There was a horizon on this planet after all. But not a mere skyline. A black streak, swiftly widening, into a band, into a wall! Its darkness was absolute, the darkness of empty space. And, incredibly, the parallel edges of this wall of shadow, instead of being curved to follow a planetary surface, were—for all any human eye could tell—perfect and unqualified straight lines.
Chapter 19
That was where the universe came to an end.
This universe, at any rate.
And they were being hurled toward that black gulf…
The wind had lost a little of its violence, but the waves grew higher and ever higher as though, somewhere ahead, they were breaking against an unseen obstacle. They hollowed now into glaucous valleys hundreds of meters deep.
At the horizon the ocean stopped dead, like the edge of a table. Beyond lay the. abyss, filling the space between the sky and the sea.
“There’s only one chance left,” Touray said. “And that’s a slim one! If a Breather comes along before…”
There was no need for him to finish. They stared, fascinated, at the edge of the world.
“Unless the wind drops,” Corson said.
Touray shrugged. “It won’t. That’s vacuum pulling us along. This whole world is going to go the same way.”
“But why?”
“Oh, something must have broken in the big machine!”
As they drew closer, the black space became populated with lights, shining motionless points which, from time to time, winked out and reappeared as though some dark object had passed in front of them. The balloon seemed to be heading toward a patch of black even more total, even more absolute, than the rest of the wall. It was haloed by bright lines that spread in all directions like forked lightning.
What it reminded Corson of was a broken window.
And that, he realized a second later, was exactly what he was looking at. A window, shattered by something dashed against it. The moveless lights were stars. That patch of blacker-than-black was a hole through which Aergistal—or at least that section of Aergistal that included the balloon—was being sucked into the void.
A colossal whirlpool bit into the surface of the sea, near the interface. The water likewise was being emptied out into nowhere.
Corson wondered whether this space was infinite, whether the whole of Aergistal with its lunatic wars, its legions and fleets and pitiable heroes, its generals and its nuclear mushrooms, would all find peace at last among those stars. Were not the creators, or the operators, of Aergistal going to step in? Was this accident beyond their powers to cope with? Or… were they simply emptying a test tube? Had Touray been right to talk about model soldiers? Could it be that after all Aergistal was nothing but an artificial world, huge but not boundless, floating in space and in the course of being drained owing to damage or by deliberate decision? What would happen if, along the fissures he could see, the “glass” shattered all of a sudden? Would the sky and the land join up again? Or would the structure of this senseless world—senseless in human terms, at least—survive forever, preserved in uncorrupting vacuum?
As the balloon approached the hole, the temperature dropped and the air grew ever thinner. Oddly, however, the gap seemed to grow narrower. A moment ago it had yawned kilometer-wide. Now, at its broadest, it was only a few hundred meters across. It was repairing itself, and swiftly at that. The balloon was so close that Corson could see circular ripples cross the interface, dying at the edges of the hole.
The sea was disappearing under an icepack which drew a white line along the straight underside of that wall of space. Not a window, then! Not a wall, even—but a force screen capable of mending itself, overloaded by an inconceivable shock.
“We’re going throughl” Touray gasped. “If it doesn’t close up too fast!”
Antonella hid her face against Corson’s shoulder. He himself, panting for breath, found energy to point toward the hole. The wreck of a vast spaceship floated in the void, a little below the level of the ocean. It might have been spindle-shaped; at any rate that was the form suggested by the stem section, which seemed to be stuck to the transparent wall. In repairing itself, the force field had trapped it.
What amazed Corson was the biological slowness of the repair process. One might better term it “healing.” He only recalled force fields which, as far as human perceptions were concerned, propagated instantly over short distances. Then he reminded himself that here the energies involved were so immense that time itself could be deformed by them. The mass equivalent of that barrier must be fantastic. Long before his own day, relativity theory had shown that time at the surface of a giant star would pass more slowly than in free space.
Even more surprising was that this time-dilation effect did not apparently extend into the space surrounding the barrier. If this was indeed a field in which time was slowed, it must have immense gravitational potential. One would have expected the balloon to be hurled toward the screen so fast that it would have burned up from friction even before it crashed.
Corson found himself able to hope again. There were only a few hundred meters to go. The healing was becoming more rapid, the fissures were vanishing. The blank black patch was shrinking. All around space seemed to glisten as though newly varnished, no doubt from a side effect of the field.
Any second now! Corson reached out to protect Antonella. Crash. Bounce! The universe spun giddily. The rope he had tied around him sawed into his ribs. He rocked, fell forward. His head struck the rim of the gondola. A steep angle. He could still hear a soft noise. The balloon smashed against the barrier, the gondola rocked. Crash. Bounce. Not so fiercely now. Something resilient in the way.
Fainted.
Chapter 20
Coolness on his forehead. He awoke. Almost at once—maybe. His head was resting on Antonella’s knees and she was wiping his face with a rag dipped in wine. He brought his hand up to his right eyebrow, which was painful, and saw blood when he withdrew it. Then he met the worried gaze of Touray.
Giddy, he sat up, and with a great effort managed to stand.
“The balloon has plugged the hole,” Touray explained.
Indeed, the gasbag was half sunk in the barrier, a good kilometer above the water, which had ceased to seethe. The underwater breach must have healed as well. The air pressure was returning rapidly to normal. Corson’s ears hurt; he pinched his nose and blew hard.
Then he leaned over the side of the gondola and stared, fascinated, into the void. Above them the sky, below them the ocean, stopped as cleanly as though they had been cut with a knife. The barrier was almost within arm’s reach. Leaning dangerously outboard, he stretched his hand toward it, but without managing to make contact. All he felt was a slight tingling which could simply have been imaginary.
Beyond was free space. But not empty space. There were stars, thousands and thousands of them in unfamiliar constellations, the sort of multicolored stars you only saw in vacuum, through a ship’s viewport or a space-suit helmet. A red splotch shone out which might be a whole galaxy very far away. And there were not only stars and galaxies to be seen.
Among and sometimes in front of them colossal battle cruisers prowled. Naturally, in spite of their size, Corson could not perceive them directly, but they made the stars twinkle, or rather distorted the path of their light. Mass and energy, he thought. A photon being such a tiny thing, so easily turned aside… Under his trained eyes the mad dance of the stars took on a pattern that made sense. Out there two fleets were engaged in desperate combat. In the course of a skirmish one of the cruisers had been disabled and slammed into the barrier so violently that it caused major damage. Doubtless unaware of this cosmic accident, the others kept on with the fight, all-important to them, but reduced on this side of the barrier to a mere abstract weaving back and forth, a shaking of space that made the stars waver like reflections on a rough sea.
