TWELVE
The briefing room into which Fazil escorted Khouri was unlike any she had ever visited. It was clearly far too large for the bubbletent to have ever held it. And while Khouri had experienced many projection devices, none of them would have been capable of displaying the thing that was now being presented to her. It covered the entire floor, across a space about twenty metres wide, and was circumnavigated by a metal-railinged walkway.
It was a map of the entire galaxy.
And what made it impossible that the map could ever have been projected by the devices with which she was familiar was one simple fact. Looking at it, she apprehended — saw, and, somehow noted — every single star in the galaxy, from the coolest, barely fusing brown dwarf up to the brightest, transient white-hot supergiant. And it was not just that every star in the galaxy was there to be noticed, if her gaze chanced upon it. It went beyond that. It was, simply, that the galaxy was knowable in one glance. She was assimilating it in its entirety.
She counted the stars.
There were four hundred and sixty-six billion, three hundred and eleven million, nine hundred and twenty-two thousand, eight hundred and eleven of them. As she watched, one of the white supergiants expired in a supernova, so she revised her count down by one.
‘It’s a trick,’ Fazil said. ‘A codification. There are more stars in the galaxy than there are cells in the human brain, so for you to know them all would tie up an undesirable fraction of your total connective memory. Which doesn’t mean that the sensation of omniscience can’t be simulated, of course.’
The galaxy was in fact too perfectly detailed to really be described as a map. Not only had every star been accorded due prominence — colours, sizes, luminosities, binary associations, positions and space velocities all represented with absolute fidelity — but there were also star-forming regions, wispish, gently glowing veils of condensing gas, in which were embedded the hottening embers of embryo suns. There were newly formed stars surrounded by disks of protoplanetary material, and — where she cared to apprehend them — planetary systems themselves, ticking round their central suns like microscopic orreries, at a vastly accelerated rate. There were also aged stars which had ejected shells of their own photospheres into space, enriching the tenuous interstellar medium: the basic protoplasmic reservoir from which future generations of stars, worlds and cultures would eventually be created. There were regular or irregular supernova remnants, cooling as they expanded and shed their energy to the interstellar medium. Sometimes, at the heart of one of these stellar death-events, she observed a newly forged pulsar, emitting radio bursts with ever-slowing but stately precision, like the clocks in some forgotten imperial palace which had been wound one final time and would now tick until they died, the time between each tick lengthening towards some chill eternity. There were also black holes in the hearts of some of these remnants, and one massive (though now dormant) one at the heart of the galaxy, surrounded by an attendant shoal of doomed stars which would one day spiral into its event-horizon and fuel an apocalyptic burst of X-rays as they were ripped asunder.
But there was more to this galaxy than astrophysics. As if a new layer of memories had been quietly overlaid over her previous ones, Khouri found herself knowing something more. That the galaxy was teeming with life; a million cultures dispersed pseudo-randomly across its great slowly rotating disk.
But this was the past — the deep, deep past.
‘Actually,’ Fazil said, ‘somewhere in the region of a billion years ago. Given that the Universe is only about fifteen times older than that, that’s quite a hefty chunk of time, especially on the galactic timescale.’ He was leaning over the railinged walkway next to her, as if they were a couple pausing to stare at their reflections in a dark, bread-strewn duckpond. ‘To give you some perspective, humanity didn’t exist a billion years ago. In fact, neither did the dinosaurs. They didn’t get around to evolving until less than two hundred million years ago; a fifth of the time we’re dealing with here. No; we’re deep into the Precambrian here. There was life on Earth, but nothing multicellular — a few sponges if you were lucky.’ Fazil looked at the galaxy representation again. ‘But that wasn’t the case everywhere.’
The million or so cultures (although she could be infinitely precise about the number, it suddenly struck her as childishly pedantic to do so, like specifying one’s age to the nearest month) had not all arisen at the same time, nor they did all hang around for the same length of time. According to Fazil (though she understood it on some basic level) it had taken until four billion years ago for the galaxy to reach the required state at which intelligent cultures could begin to arise. But once that point of minimal galactic maturity had been reached, the cultures had not all suddenly appeared in unison. It had been a progressive emergence of intelligence, some cultures having arisen on worlds where, for one reason or another, the pace of evolutionary change was slower than the norm, or life’s ascendancy was subject to more than the usual quota of catastrophic setbacks.
But eventually — two or three billion years after life had first arisen on their homeworlds — some of these cultures had become spacefaring. When that point was reached, most cultures expanded rapidly into the galaxy, although there were always a few stay-at-homes who preferred to colonise only their own solar systems, or sometimes even just their own circum-planetary environments. But generally the pace of expansion was rapid, with a mean drift rate between one tenth and one hundredth of the speed of light. That sounded slow, but was in fact blindingly fast, given that the galaxy was billions of years old and only a hundred thousand light-years wide. Unrestricted, any of these spacefarers could have dominated the entire galaxy in the totally inconsequential time of a few tens of millions of years. And maybe if it had happened like that — a neatly imperialist domination by one power — things would have been very different.
But instead, the first culture had been at the slower end of the expansionist speed-range, and had impacted on the expansion wave of a second, younger upstart. And while younger, the second civilisation was not technologically inferior to the first, nor less capable of mustering aggression when it was required. There was what — for want of a better word — one might describe as a galactic war; a sudden sparking friction where these two swelling empires brushed against one another, grinding like vast flywheels. Soon, other ascendant cultures were embroiled in the conflict. Eventually — to one degree or another — several thousand spacefaring civilisations fell into the fray. They had many names for it, in the thousand primary languages of the combatants. Some of these names could not easily be translated into any meaningful human referent. But more than one culture called it something which might — with due allowance for the crudities of interspecies communication — be termed the Dawn War.
It was a war encompassing the entire galaxy (and the two smaller satellite galaxies which orbited the Milky Way) — one which consumed not just planets, but whole solar systems, whole star systems, whole clusters of stars, and whole spiral arms. She understood that evidence of this war was visible even now, if one knew where to look. There were anomalous concentrations of dead stars in some regions of the galaxy, and still-burning stars in odd alignments; husked components of weapons-systems light-years wide. There were voids where there ought to have been stars, and stars which — according to the accepted dynamics of solar-system formation — ought to have had worlds, but which lacked them: only rubble, cold now. The Dawn War had lasted a long, long time — longer even than the evolutionary timescale of the hottest stars. But on the timescale of the galaxy, it had indeed been mercifully brief; a transforming spasm.
