‘I don’t understand, Frank.’
‘Maybe it’s better that you don’t.’
The truth? No, she thought. Maybe for these wretched creatures, here on this bizarre star relic. Not for us; not for humans, the solar system. Even if this is the cosmos’s cruel logic, why do we have to submit to it? Maybe we ought to find a way to fix it.
Maybe Reid Malenfant would know the answer to such questions by now – wherever he was, if he was still alive. She wondered if it would ever be possible to find him.
… But none of that mattered now, for electric blue light enveloped her, like fusion summer.
Chapter 10
TRAVELS
And, far from home, here was Malenfant, all alone save for a sky full of Gaijin, orbiting a planet that might have been Earth, circling a star that might have been the sun.
He peered down at the planet, using the telescopic features of his softscreen, for long hours. It might have been Earth, yes: a little heavier, a little warmer, but nevertheless compellingly familiar, with a jigsaw arrangement of grey-brown continents and blue oceans and streaky white clouds and even ice caps, all of it shining unbearably brightly. Was that textured greenery really forest? Did those equatorial plains breed some analogy of grass? And were those sweeping shadows great herds of herbivores, the buffalo or reindeer of this exotic place?
But, try as he might, he found no sign of intelligent life: no city geometries, no glowing artificial light, not even the thread of smoke or the sprinkling of firelight.
This wasn’t a true copy of Earth. Of course not, how could it be? He knew there was no Africa here, no America, no Australia; these strange alien continents had followed their own long tectonic waltz. But those oceans really were made of liquid water – predominantly anyhow – and the air was mainly a nitrogen – oxygen mix, a bit thicker than Earth’s.
Oxygen was unstable; left to itself it should soon combine with the rocks of the planet. So something had to be injecting oxygen into the atmosphere: free oxygen was a sure sign of life – life that couldn’t be so terribly dissimilar to his own.
But that atmosphere looked deeper, mistier than Earth’s; the blue of the oceans, the grey of the land, had a greenish tinge. And if he looked through the atmosphere towards the edge of the planet, he could see a pale yellow-green staining, a sickly, uncomfortable colour. The green was the mark of chlorine.
He tried to explain to his Gaijin companion, Cassiopeia, what it was that kept him staring down at this new world, long after he had exhausted the analytic possibilities of his eyeball scrutiny. ‘Look down there.’ He pointed, and he imagined interpretative software aligning his finger with the set of his eyes.
IT IS A PENINSULA.
‘True …’ Pendant from a greater continent, set in a blue equatorial sea, and surrounded by blue-white echoes of its outline, echoes that must be some equivalent of a coral reef. ‘It reminds me of Florida. Which is a region of America –’
I KNOW OF FLORIDA. THIS PENINSULA IS NOT FLORIDA. Over the months (subjective) they’d been together, Cassiopeia’s English had got a lot better, and now she spoke to him using a synthesized human voice relayed over his old Shuttle EMU headset.
‘But it’s like Florida. At least, enough to make me feel …’
WHAT?
He sighed.
It had taken him forty years to get here from Alpha Centauri – including around six months of subjective time, as he had coasted between various inner systems and Saddle Point gateways. System after system, world after world. Six months as he had tried to get to know the Gaijin, and they to know him.
It seemed very important to them that they understood how he saw the universe, what motivated him. As for himself, he knew that understanding was going to be the only way humans were ever going to deal with these strangers from the sky.
But it was hard.
Cassiopeia would never have picked out that peninsula’s chance resemblance to Florida. Even if some mapping routine had done it for her, he supposed, it would have meant nothing, save as an example of convergent processes in geology. The Gaijin sought patterns, of course – it was hard to imagine a science which did not include elements of pattern recognition, of correlation and trend analysis – but they were not distracted by them, like humans.
No doubt this was simply a product of differing evolutionary origins. The Gaijin had evolved in the stately stillness of deep space, where there was, in general, time to think things through; humans had evolved in fast-moving, crowded environments where it paid to be able to gaze into the shadows of a tree, a complex visual environment of dapples and stripes, and pick out the tiger fast.
But the end-result was that he simply could not communicate to Cassiopeia why it pleased him to pick out an analogue of Florida off the shore of some unnamed continent, on a planet light years from Earth.
Cassiopeia was still waiting for a reply.
‘Never mind,’ he said. He opaqued the membrane and began his routine for sleep.
Talking to aliens:
It didn’t help that he didn’t really have any idea who, or what, he was talking to.
He had no idea how complex an individual Gaijin was. Was Cassiopeia equivalent to a car, a bacterium, a person, something more?
And the question might have no meaning, of course. Just because he communicated with a discrete entity he called Cassiopeia, it didn’t mean there had to be anything like a corresponding person behind his projection. Maybe he was talking to a limb, or a hand, or a digit, of some greater organism – a super-being, or some looser Internet of minds.
Still, he had found places to start. His first point of contact had been navigation.
Both he and Cassiopeia were finite, discrete creatures embedded in a wider universe. And that universe split into obvious categories – space, stars, worlds, you, me. It had been straightforward to agree on a set of labels for Sol, Earth and the nearby stars – even if that wasn’t the custom of the Gaijin. They thought of each star as a point on a dynamic four-dimensional map, defined not by a name but by its orientation compared to some local origin of coordinates. So their label for Sol was something like get-to-Alpha-Centauri-and-hang-a-left-for-four-light-years … except that Alpha Centauri, the local centre of Gaijin operations, was itself defined by an orientation compared to another, more remote origin of coordinates – and so on, recursively back, until you reached the ultimate origin: the starting point, the home world of the Gaijin.
And this recursive web of directions and labelling was, of course, subject to constant change, as the stars slid through the sky, changing their orientations to each other.
It was a system of thinking that was logical, and obviously useful for a species who had evolved to navigate among the stars – a lot more so than the Earthbound human habit of seeking patterns in the random lamps of the sky, patterns called constellations, which shifted because of perspective if you moved more than a couple of light years from Earth. But it was a system that was far beyond the capacity of any human mind to absorb.
Another point of contact: You. Me. One. Two. In this universe, it seemed, it was impossible not to learn to count.
Malenfant’s math extended (shakily) as far as differential calculus, the basic tool mathematicians used to model reality. It did appear that Cassiopeia thought of the world in similar terms. Of course, Cassiopeia’s mathematical models were smarter than any human’s. The key to such modelling was to pick out the right abstractions from a complex background: close enough to reality to give meaningful answers, not so detailed they overwhelmed the calculations. For the Gaijin, the boundaries of abstraction and simplification were much further back than any human’s, her models much richer.
And there were more fundamental differences. Cassiopeia seemed much smarter at solving the equations than Malenfant, or any human. He managed to set out for her the equations of fluid mechanics, one of his specialities at college, and she seemed to understand them qualitatively: she could immediately see how thes
e equations, which in themselves merely described how scraps of flowing water interacted with each other, implied phenomena like turbulence and laminar flow, implications it had taken humans years – using sophisticated mathematical and computational tools – to tease out.
Could Cassiopeia look at the equations of relativity and see an implied universe of stars and planets and black holes? Could she look at the equations of quantum mechanics and see the intricate chemistry of living things?
Of course, that increased smartness must lead to a qualitative jump in understanding. A chimp didn’t think about things more simply than Malenfant did; it couldn’t grasp some of his concepts at all. There were clearly areas where Cassiopeia was simply working above Malenfant’s wretched head.
Cassiopeia had spent time trying to teach him about a phenomenon just a little beyond his own horizon – as chaos theory might have been to an engineer of, say, the 1950s. It was something to do with the emergence of complexity. The Gaijin seemed able to see how complexity, even life, naturally emerged from the simplest of beginnings: not fundamental physical laws, but something even deeper than that – as far as he could make out, the essential mathematical logic which underlaid all things. Human scientists had a glimmering of this. His own DNA somehow contained, in its few billion bases, enough information to generate a brain of three trillion connections …
But for the Gaijin this principle went further. It was like being given a table of prime numbers and being able to deduce atoms and stars and people, as a necessary consequence of the existence of the primes. And since prime numbers, of course, existed everywhere, it followed there was life and people, humans and Gaijin, everywhere there could be.
Life sprouting everywhere, like weeds in the cracks of a pavement. It was a remarkable, chilling thought.
‘Take me to your home,’ he’d said one day.
Cassiopeia’s choice of a human label for her remote home was Zero-Zero-Zero-Zero, the great sky map’s origin of coordinates.
I AM THE SUCCESSOR OF A REPLICANT CHAIN WHICH EMERGED THERE. I am descended from emigrants? Not exactly, because she went on: I RETAIN RECORDS OF ZERO-ZERO-ZERO-ZERO. Memories? Did each Gaijin come to awareness with copies of the memories of those who bore her – or constructed her? Were they, then, her memories, or a mere copy? IT IS POSSIBLE TO TRANSLATE TO ZERO-ZERO-ZERO-ZERO. THERE IS NO PURPOSE.
‘I’d like to see it.’
THERE ARE RECORDS WHICH –
‘Your records only show me your world through your eyes. If we’re ever going to understand each other, you have to let me see for myself.’
There was a long hesitation after that.
FINALLY.
‘What?’
THERE ARE MANY PLACES TO SEE. MANY WORLDS. BEFORE ZERO-ZERO-ZERO-ZERO.
‘I understand. One day …’
ONE DAY.
But not today, Malenfant thought, as he opened his eyes to the light of a foreign sun. Not today. Today, we are both far from home.
Cassiopeia provided him with an environment suit, a loosely cut coverall of what felt like a high-grade plastic. It had no zippers; he learned to seal it up by passing his thumb along the open seams. He lifted a hood-like helmet over his head. There was a clear faceplate, a slightly opaque filter near his mouth.
There was no independent air supply, just one layer of fabric. The whole thing jarred with Malenfant’s intuition of the protection he would need to walk on an alien world. But Cassiopeia assured him it would be enough. And besides, the only alternative was his battered Shuttle EMU suit, still with him, crammed into a corner of the lander, his only possession, long past its operational lifetime.
‘Open the door. Please.’
The lander door dilated away. The world beyond was green and black.
The lander’s cabin floor was almost flush with the ground, and he stepped out, pace by pace, testing his suit. Gravity was a little more than Earth normal, comfortingly familiar, and the air pressure just a little higher than Earth’s sea level.
First impressions:
He was in an open forest, like park land. There were objects that were recognizably trees, about the size of Earth trees, and what appeared to be grass under his feet. Above his head a sun sailed through a sky littered with high, wispy cirrus clouds.
He closed his eyes. He could hear the soft hiss of wind over the grass, and a distant piping, for all the world like a bird’s song, and when he breathed in he filled his lungs with cool, crisp air.
It might have been Earth.
But, when he opened his eyes, he saw a sky that was a lurid yellow-green. It was like a haze of industrial smog. The vegetation was a very deep green, almost black.
And he could smell chlorine.
His filter removed all but a trace of the chlorine compounds that polluted the atmosphere – including phosgene, toxic stuff humans had once used to slaughter each other. If not for his suit, this friendly-looking world would soon kill him.
Chlorine: that was the big difference here. Most of Earth’s chlorine was locked up in the oceans, in the form of a stable chloride ion. This world seemed to have started out as roughly Earth-like. But something, one small detail, had been different: here, something had pumped all that chlorine into the air.
He walked forward, over grass that crushed softly under his feet.
He reached a narrow valley, a rushing brook. There was a stand of trees nearby. The bed of the little stream was just a soft muddy clay, no sign of any rocks. The water was colourless, clear. He knelt down, stiffly, and dipped his fingers into the water. It was cold, its pressure gentle against his gloved hands.
WARNING. SOLUTION OF HYDROGEN CHLORIDE. HYPOCHOLOROUS ACID.
He snatched back his fingers. Like a swimming pool, he thought: chlorine plus water gave a solution of acid and bleach. The weathering of any rocks here must be ferocious; no wonder only clays survived.
He straightened up to inspect a tree. He touched branches, leaves, a trunk, even blossom. But to his gloved fingers the leaves felt slippery, soapy.
From a hollow in the tree trunk, at about his eye level, a small face peered out: the size and shape of a mouse’s, perhaps, but with a central mouth, three eyes arranged symmetrically around it. The mouth opened, showing flat grinding surfaces, and the little creature hissed, emitting a cloud of greenish gas. Then it ducked back into the hole, out of his sight.
The trunk didn’t feel like wood. He reached up and broke off a twig; it snapped reluctantly. The interior was springy, fibrous. The leaves, the tree trunk, were made of some kind of natural plastic – perhaps a form of polyvinyl chloride, PVC. If he could smell the blossom, it would surely stink like toxic waste.
It was like a grotesque model of a tree, a thing of plastic and industrial waste. And yet the breeze ruffled it convincingly, and sunlight dappled the green-black grass beneath.
In his ear, Cassiopeia, from orbit, began to lecture him about biochemistry. THE LIVING THINGS HERE ARE CONSTRUCTED OF CELLS – ANALOGOUS TO LIVING THINGS ON EARTH, TO YOU. THEIR METABOLISM IS NOT TOLERANT OF THE CHLORINE. BUT THEY HAVE EVOLVED SHIELDING AT THE CELLULAR LEVEL …
He interrupted. ‘There are trees here,’ he said. ‘Grass. Flowers. Animals.’ You see biochemistry. I see a flower.
There was a long silence.
It was the Gaijin way of seeing reality: from the equations of quantum mechanics, working up to a world. But that wasn’t the way Malenfant thought. Humans, it seemed, were better at broad comprehension than the Gaijin, quicker at abstracting simplicity from complexity. This object before Malenfant wasn’t a tree, because trees only grew on Earth. But it helped Malenfant to think in those terms, to seek patterns and map them back to what he knew.
The Gaijin, slowly, were learning to ape his thinking.
YES, came the reply. THERE ARE TREES.
‘Cassiopeia. Why did you bring me here, to this chlorine-drenched waste dump?’
TO GATHER MORE DATA, MALENFANT.
Malenfant scowled at the s
ky.
The Gaijin seemed to be trying to educate him, for purposes of their own. They had shown him worlds, all of them very different, all of them bearing life. All of them scarred, in some way.
The Gaijin saw the universe as some immense computer program, he was coming to believe, an algorithm for generating life and, presumably, mind wherever and whenever it could.
The trouble was, the program had bugs.
He grunted. ‘All right. Where? How?’
WALK A KILOMETRE, TOWARDS THE SUN.
Muttering complaints, sipping cool water from a pipe inside his hood to dispel the swimming-pool taste of chlorine, he stalked on.
And, long before the kilometre was covered, he found people.
There was a crowd of them, a hundred or more, gathered around what appeared to be a pit in the ground. They moved in a kind of dance, chains of people weaving in and out to a murmur of noise, soft as a wind blowing.
Most of the dancers appeared to be somewhere near his own height. Few were taller, but several were a lot smaller – children? The elderly, withered by age?
Not humans, of course. But people, yes.
He glanced around, seeking cover. But Cassiopeia reassured him.
THERE IS A PERCEPTUAL DYSFUNCTION, MALENFANT. They can’t see you.
‘Why not? … Oh. Captain Cook.’
COMMUNICATION DYSFUNCTION.
There was a story – probably apocryphal – that on one of the islands visited by Cook, the natives had been unable even to see his great exploratory ships. They had never encountered such large floating artefacts before. It was only when Cook’s crew put out in landing boats that the natives were able to comprehend.
Thus, Malenfant was simply too strange an element in the dancers’ world for them to perceive.
‘… Never mind. Humans have limits like that too.’
Feeling a little bolder, he stepped forward, looked more closely.
He picked out one of the dancers. She (he decided arbitrarily) stood upright. She had a clearly defined torso and head, sets of upper and lower limbs. But she had three of everything – three arms, three legs – and her limbs articulated back and forth in a complex, graceful way he found unnerving. She didn’t walk, exactly, shifting her weight from foot to stomping foot as he did. Rather, she spun around, whirling, letting one foot after another press lightly on the ground. It was high speed and difficult to follow, like trying to figure out how a horse ran; but after he’d watched for a few seconds it seemed easy and natural.
