About the Author

Gregory Benford is an American science fiction writer born on January 30, 1941, in Mobile, Alabama. Along with his twin brother Jim Benford, who like him went on to a career in physics, he was active in science fiction fandom in the 1950s and 1960s; the two brothers co-founded the well-regarded science fiction fanzine Void, which was later co-edited by Ted White, Peter Graham, and Terry Carr. Benford began selling SF professionally in 1965, with "Stand-in" in The Magazine of Fantasy and Science Fiction. Since then he has published many short stories and well over two dozen novels. Timescape (1980), an ambitious and well-wrought SF novel notable for its close depictions of how twentieth-century science is actually done, won the Nebula Award and the John W. Campbell Award. He has won one other Nebula, for the novelette "If the Stars Are Gods" co-written with Gordon Eklund. Aside from Timescape, Benford is probably best-known for his far-future, often lyrical "Galactic Center" novels: In the Ocean of Night (1976), Across the Sea of Suns (1984), Great Sky River (1987), Tides of Light (1989), Furious Gulf (1994), and Sailing Bright Eternity (1995). Gregory Benford lives in Southern California, where he is a professor of physics at the University of California at Irvine.

GREGORY BENFORD teaches at the University of California and lives in Irvine, California. Benford is a winner of the United Nations Medal for Literature, and the Nebula Award for his novel Timescape. In 1995 he received the Lord Prize for contributions to science. Benford conducts research in plasma turbulence theory and experimentation, and in astrophysics. He has published well over a hundred papers in fields of physics from condensed matter, particle physics, plasmas and mathematical physics, and several in biological conservation.

CHAPTER 1

We are blooming flowers on the plain — which He picks.

— Old hymn

He suddenly thought that they had not seen anyone for quite a while. Amid the vast voyages, adventures, striking vistas — and yes, while basking in symphonies of sensation — they had not needed company.

Even as twilight closed in. But now —

"Do you recall —?" He asked, turning to Her, and could not recall an ancient name. Names were unimportant, mere symbols, yes ... but He did remember that names had existed to distinguish between multitudes. When? First task: to name the beasts. When had He and She said that?

"I do," She said mildly, for She was always mild. "Any: one. A logical category."

"They were Other, yes. I recall. Lesser but Other."

"Just so."

Thoughts rippled light-quick among them. The concept of Other as separate and different commingled in a burst of flavors–musky, crisp, sweet, sad, noisy — and tempted him. Somehow, in the long run of time they shared, the portions of himself and herself had moved away from overt Others, leaving the two of them to interweave as their binary Self. The details of why had quite washed away.

Yet the Others were part of him and her, and He and She could bring them forward when needed or desired. And desire played a role in all of this. Memories strummed, mellow notes rang redly, old victories sang and trilled.

The Others were good company, He thought.

Desire radiated from them both. They were, of course, the two who gave tension to this finite, bounded existence. This universe. Duality was fundamental, as was helicity itself, which necessarily had to be included in this exponentially expanding space-time.

How long now, since the Beginning? He wondered. The question did not actually have deep meaning, He saw, because in the early stages space and time were so entwined, feeding each other. Duration did not endure, after all.

Still, the end of all this was sharp, clear. The accelerating expansion had calmed, died, and the great coolness descended. Time coiled now, in the final, languid waltz between space and time.

She nodded at the firmament around them, saying, "Let us have Others again." — and brilliant acrid displays frothed, with ruby scents, soft gliding pleasures and deep bass rolls, all blending with the views. They swam in coasting galactic clusters, amid simmering amber stars, and worlds and variety beyond measure — or at least, measures that He and She now cared about. In the long past times, near the very start of all this, they had needed to be more careful. Not now.

The firmament shuddered, rumbled, brimmed. A fresh persona came gliding toward them, swimming in liquid light.

"You called me forth?" the self said, and He saw it had no sex. It did not need any. She and He did need that, had from the Beginning. Sultry love and sex were the essence of the great dance. But sex was not necessary in their subselves, the Others.

"You are One," He said.

"Yes! Such joy," One said with liberated intelligence. "You wanted me to become overt, not buried in your inner self? Why?"

Fondly, He recalled that this ancient way — allowing a subself to manifest, bringing a different, fresh perspective — meant questions. Always questions. "For company. If needed, many of you, for ... interest."

To have someone independent to talk to, He thought but did not say. To summon up insights that lie within the two of us, but that we cannot express overtly. To be vast meant having parts of yourself that you could not readily find. The uncoiling of space-time had taken long eras of detail that rolled on without inspection — that was the function of natural law.

One said, "I was in my mortal time a human. We had many visions of you."

"Human?" asked She.

"One of the ancient variants," He explained, for to Him went the tedious detail work of categories. "They appeared quite early. A type that our worlds quite commonly brought forth."

He looked long at One and took pity upon this pale mote before them. "You are from a common kind, those of four appendages. A local optimum, from natural selection, acting where beings sprung from the most likely place where life began — that is, in the realm of gravitation. You and others such must fight and profit from the press of gravity."

She remembered. "Ah. The dwellers among worlds, yes — they are among our best work."

Still, He recalled, the total amount of information that One could absorb in its mortal lifetime was about 1016 bits, which severely limited what it could distinguish. Since its death, it had dwelled within He and She, and so had taken in vastly more. But knowledge was not wisdom, as made clear by One's inner confusions, which He could see easily.

One hesitated. "May I ask ... why? Why did you call me forth?"

She said, "Because this is the end time. We want to bask in your light once more."

The One seemed to fathom this compliment, though of course it could not be true. "We had a poet, Milton, who thought you would suffer from loneliness."

Together they laughed — and the One was startled that they did. This made them laugh again. "A hominid narrow idea," She said, mirth rippling through her.

He reached into her and felt the surges of emotion, saw echoes them in his own, larger self, and loved her all the more. Alone? Never.

Around them time hammered on, as it must — that was one of the basic constraints designed in from the Creation, of course. He realized that the One was worrying through an ancient problem, one expressed in musty eras and epochs long past. But persistent.

"Is there a fresh challenge, then?" One said.

She said, "In a way. The laws grind."

One said, "Of course. That is the way You set."

"Just so," She said. "But now it leaches meaning from all."

"That was inevitable?" One wondered.

"Disorder gathers unavoidably," He said.

One registered sharp colors of surprise. "Can you not —?"

"A finite system may be capable of an infinite amount of computation, in due time," He said. "But it can only store a finite number of memories."

"And you are finite?" One was perplexed.

"Necessarily," She said. "We dwell in a bounded space-time."

He said, "The initially finite must remain so."

She added, "Any additional mass with which to build new 'memory' has redshifted beyond the event horizon, no matter where we are — and is therefore unavailable."

The One said slowly, "Inescapably?"

"Life itself is doomed to mortality," He said with finality. This was going slower than it should. He had forgotten that about Others.

One said strongly, "I do not accept this."

At last, the point. She said with love and deep feeling, "Then strive to alter."

* * *

A vast age passed. The last suns dimmed into red sleep. Through it all, One and those he represented — the faithful — labored long and hard. Crafty and deft, they could manifest in the universe through mechanisms He and She opened for them. It was at least amusing to watch, and always interesting. This was how the universe taught itself.

The faithful built great arches of slumbering mass, cobbled together from whole clusters of dead galaxies. The basic energy of the expansion then stretched these fresh structures. Vast motors worked like elastic bands, extending and releasing, harnessing the swelling of space-time itself. These extracted useful energy, avoiding the dead end of collapsed matter. Energies burst forth and new life forms of plasma flourished. The faithful watched these beings, far larger than the dark galaxies, frolic in what was, for them, a fresh new universe.

* * *

Vastly later, One approached He and She again. "We dedicate these young plasma civilizations to you."

She said, "Excellent! Your works are wondrous. We are happy to witness them."

One rippled with a bright frisson of pleased color. "We estimate that the young ones can persist for as long as the older life — born of silicon and even raw dust — can endure."

She said, "True, at least until the protons decay."

One beamed. "After that, there is no fundamental reason that information cannot be lodged in electron-positron plasmas, or even atoms made from them. So the plasma forms will go on eternally. Your laws demand that we change our physical basis. We the faithful shall now transform into those diffuse structures. For your eternity, as promised."

She said, "No, not eternity. That is the Law."

One rippled with puzzlement and gray despair. "But if even You cannot —"

"We wrote all this into the Beginning," He said to One.

This had been clear even in the long, bright era when light flared everywhere. The accelerating expansion of space-time, which was essential in the planning of all this, none the less yielded a more constricted long-term future. For long ages now, galaxies had faded from view, ebbed, and shifted more and more into the deep red. They seemed to run slower and slower as well, due to the expansion. But now all that even He and She could witness had frozen. All about them lay galaxies still, dark and ever-colder, seizing up.

The One said with fizzing, fast energies, "But what of we!?"

Both She and He realized that One spoke now for all mortals, including the giddy plasma forms that fizzed and jostled in the darkening skies. One and his kind arose from the intricate wealth of biology, and had sensed the existence of He and She behind the lattice that was this universe. They had once lived their small lives in small worlds.

"You," She said, "our faithful."

"Yes! One said. "We believed that the universe had to have come from a Someone. You."

He said, "We two made our Creation so it led to this encroaching night, also."

"Ah ..." Carefully, One went on, "So how can we persist? The energy stores of your universe are thinning out as the expansion accelerates."

She said sympathetically, "Any conceivable form of life would have to keep ever-cooler, think slowly, and hibernate for ever-longer periods. So with you, as well."

One did not seem to think this was an answer. "New, fresh life — yes. But what of we?"

She noticed One's troubled flex of color and desire. "Those mortals who believed that this universe had purpose, and so gained a place within He or Me?"

One said eagerly, "Yes!"

The two regarded each other for a microsecond. So this question came at last. "All winds down," He said in a long, slow way. "Energies mingle and collide. Those drive life in evolving systems. Such vexation is necessary — it builds structure, a fountain of bright wonder."

One said slowly, "I ... suppose."

He went on explaining, for this was a large lesson — one He and She had been forced by logic to learn, back before the Beginning. To have such a vibrant universe, they had to dwell within it, not stand separate. "But you must see, there is a price. Creation ebbs. We cannot question the Law. We made it, because a finite yet unbounded system — this, our Creation — must have such Law to exist at all."

She said, "Otherwise, Creation does not generate interesting structures."

"And that was our aim," He added. "The reason we did all this."

One said quickly, as if fearing the fading amber tides in the vexed sky would cut it off, "You made this all for eternity — that we believed! You said so."

She corrected, "We did not. Yourselves, all you mortals, you said so. Not us."

One insisted, "The assembled Host, we who worshipped you — we thought that time would spool on for eternity."

"Eternity depends upon the system of measuring it," She said abruptly.

One paused. "This place with You — vast spaces beyond measure, time within grace — is the wonder we all hoped for ..."

She said, "We designed for that, yes."

One said softly, "... as our eternal resting place."

He saw One's problem. "You are finite beings. You do not know of the many ranks of infinity. Within those vast legions, the band of infinities, some entries are larger than other. It is the only way that Measure — which you would call mathematics — can be ruled by logic."

This idea came buttressed with transfinite realms of suggestion. He let these spill out into the One, so that the finite being could perhaps understand. That small blessing might help in what was to come.

"Thank you —" the One said, then fell silent as it digested the realms of infinities. These cascaded around it in analytic rainbows. She and He watched them have their impact. Ramparts of theorems, clusters of corollaries. Axioms stacked in stretching libraries of rigid reason. In this rumbling cascade One struggled, juggling concepts beyond any finite being.

One fought up from this and finally said, "We all, the Host — we have dwelled here in your firmament. In wonder. Surely that is the promise all our faiths held forth."

He and She said together, "We are constrained. For this universe we made to give forth such vast wonders, all had to run down."

One said rapidly (for the clocks of eternity were racing now), "But you saved us!"

She said, "From your little deaths, yes. Not from the necessity of Law."

One paused, as shadows drew longer around them, and hissing colors lashed up on wrecked horizons. Then One said in vexed tones, "We have lived on, far past our wretched small beginnings. Lived in ecstasy. Lived in our private deliriums of desire, sensation, comfort beyond measure —"

"We know. We designed it for you," She said flatly.

He recalled. Long ago, One — and the multitude of mortals who had lived their self-aware lives since the Creation — had learned the durable crafts that logic taught. The secret of their survival amid cooling space-time lay in cooling down. Those spirits who had faith did dwell in their small ecstasies, yes. They learned as Creation itself ebbed, using up the Beginning's store of energies. Being frugal meant that those who by faith dwelled with He and She could dole out ever-smaller drops of the precious, finite energy necessary to live, to think. The mortals called it Heaven.

The mortals thought in digital systems. They were like rachets that, once kicked forward, cannot go back. As the universe cools, they eventually could not kick the rachet far enough forward.

"But this betrays us!" One said as loudly as a finite thing can.

"No," He said, "not betrayal. The final truths stretch beyond your understanding. That is all."

Silence. One rested for a tick of time. Streamers arced through it, but brought little pleasure.

Shuddering with pale joy, One said, "I ... I know that. We all do."

The three of them enjoyed the play of space and time, a froth of events.

Then One said, uncertainly, "We ... we were promised — admittedly, by texts we wrote ourselves, though they seemed inspired by You — eternal life."

She understood, but said firmly, "To bring you forth at all demanded a universe that cannot last."

"But — eternity — in heaven — that is what we thought —"

"Your thoughts are finite, as you are." He knew that this last era was the moment to be completely clear, as fading redness grew around them. Stars now burst in their final finery, and galaxies shuddered in long, acoustic waves. Dark motes ate at the hearts of the last star swarms, frying in the sky.

One stopped, regarding Them. "But must it be that You, who made and dwell in this cosmos, share the Law?"

She said solemnly, "It must."

One said it softly. "You must obey the Law you made?"

"Of course." He saw that this transfinite logic had escaped all those who invested this realm with their faith. Was it always so? This little One, for example, had the mind of a narrative-addicted human. Such beings, swimming in time, thought that the end of a story tells its meaning.

"We will die!"

"Yes."

Slowly, reluctantly, the One said, "Did you have no choice in the Beginning?"

"Limited ones," She said.

"To create variety, and spontaneous order of creative kinds," He added, "we were much constrained."
