59 – Trinity

'That was well done. Now they will not be tempted to return.'

'I am learning many things; but I still feel sad that my old life is slipping away.'

'That too will pass; I also returned to Earth, to see those I once loved. Now I know that there are things that are greater than love.'

'What can they be?'

'Compassion is one. Justice. Truth. And there are others.'

'That is not difficult for me to accept. I was a very old man, for one of my species. The passions of my youth had long since faded. What will happen to – to the real Heywood Floyd?'

'You are both equally real. But he will soon die, never knowing that he has become immortal.'

'A paradox – but I understand. If that emotion survives, perhaps one day I may be grateful. Should I thank you – or the Monolith? The David Bowman I met a lifetime ago did not possess these powers.'

'He did not; much has happened in that time. Hal and I have learned many things.'

'Hal! Is he here?'

'I am, Dr Floyd. I did not expect that we should meet again – especially in this fashion. Echoing you was an interesting problem.'

'Echoing? Oh – I see. Why did you do it?'

'When we received your message, Hal and I knew that you could help us here.'

'Help – you?'

'Yes, though you may think it strange. You have much knowledge and experience that we lack. Call it wisdom.'

'Thank you. Was it wise of me to appear before my grandson?'

'No: it caused much inconvenience. But it was compassionate. These matters must be weighed against each other.'

'You said that you needed my help. For what purpose?'

'Despite all that we have learned, there is still much that eludes us. Hal has been mapping the internal systems of the Monolith, and we can control some of the simpler ones. It is a tool, serving many purposes. Its prime function appears to be as a catalyst of intelligence.'

'Yes – that had been suspected. But there was no proof.'

'There is, now that we can tap its memories – or some of them. In Africa, four million years ago, it gave a tribe of starving apes the impetus that led to the human species. Now it has repeated the experiment here – but at an appalling cost.

'When Jupiter was converted into a sun, so that this world could realize its potential, another biosphere was destroyed. Let me show it to you, as I once saw it...'

Even as he fell through the roaring heart of the Great Red Spot, with the lightning of its continentwide thunderstorms detonating around him, he knew why it had persisted for centuries, though it was made of gases far less substantial than those that formed the hurricanes of Earth. The thin scream of hydrogen wind faded as he sank into the calmer depths, and a sleet of waxen snowflakes – some already coalescing into barely palpable mountains of hydrocarbon foam – descended from the heights above, It was already warm enough for liquid water to exist, but there were no oceans here; this purely gaseous environment was too tenuous to support them.

He descended through layer after layer of cloud, until he entered a region of such clarity that even human vision could have scanned an area more than a thousand kilometres across. It was only a minor eddy in the vaster gyre of the Great Red Spot; and it held a secret that men had long guessed, but never proved.

Skirting the foothills of the drifting foam mountains were myriads of small, sharply defined clouds, all about the same size and patterned with similar red and brown mottlings. They were small only as compared with the inhuman scale of their surroundings; the very least would have covered a fair-sized city.

They were clearly alive, for they were moving with slow deliberation along the flanks of the aerial mountains, browsing off their slopes like colossal sheep. And they were calling to each other in the metre band, their radio voices faint but clear against the cracklings and concussions of Jupiter itself.

Nothing less than living gasbags, they floated in the narrow zone between freezing heights and scorching depths. Narrow, yes – but a domain far larger than all the biosphere of Earth.

They were not alone. Moving swiftly amongst them were other creatures, so small that they could easily have been overlooked. Some of them bore an almost uncanny resemblance to terrestrial aircraft, and were of about the same size. But they too were alive – perhaps predators, perhaps parasites, perhaps even herdsmen.

And there were jet-propelled torpedoes like the squids of the terrestrial oceans, hunting and devouring the huge gasbags. But the balloons were not defenceless; some of them fought back with electric thunderbolts and with clawed tentacles like kilometre-long chainsaws.

There were even stranger shapes, exploiting almost every possibility of geometry – bizarre, translucent kites, tetrahedra, spheres, polyhedra, tangles of twisted ribbons... The gigantic plankton of the Jovian atmosphere, they were designed to float like gossamer in the uprising currents, until they had lived long enough to reproduce; then they would be swept down into the depths to be carbonized and recycled in a new generation.

He was searching a world more than a hundred times the area of Earth, and though he saw many wonders, there was nothing here that hinted of intelligence. The radio voices of the great balloons carried only simple messages of warning or of fear. Even the hunters, who might have been expected to develop higher degrees of organization, were like the sharks in Earth's oceans – mindless automata.

And for all its breathtaking size and novelty, the biosphere of Jupiter was a fragile world, a place of mists and foam, of delicate silken threads and paper-thin tissues spun from the continual snowfall of petrochemicals formed by lightning in the upper atmosphere. Few of its constructs were more substantial than soap bubbles; its most terrifying predators could be torn to shreds by even the feeblest of terrestrial carnivores.

'And all these wonders were destroyed – to create Lucifer?'

'Yes. The Jovians were weighed in the balance against the Europans – and found wanting. Perhaps, in that gaseous environment, they could never have developed real intelligence. Should that have doomed them? Hal and I are still trying to answer this question; that is one of the reasons why we need your help.'

'But how can we match ourselves against the Monolith – the devourer of Jupiter?'

'It is only a tool: it has vast intelligence – but no consciousness. Despite all its powers – you, Hal and I are its superior.'

'I find that very hard to believe. In any event – something must have created the Monolith.'

'I met it once – or as much of it as I could face – when Discovery came to Jupiter. It sent me back as I am now, to serve its purpose on these worlds. I have heard nothing of it since; now we are alone – at least for the present.'

'I find that reassuring. The Monolith is quite sufficient.'

'But now there is a greater problem. Something has gone wrong.'

'I did not think I could still experience fear...'

'When Mount Zeus fell, it could have destroyed this whole world. Its impact was unplanned – indeed, unplannable. No calculations could have predicted such an event. It devasted vast areas of the Europan seabed, wiping out whole species – including some for which we had high hopes. The Monolith itself was overturned. It may even have been damaged – its programs corrupted. Certainly they failed to cover all contingencies; how could they, in a Universe which is almost infinite, and where Chance can always undo the most careful planning?'

'That is true – for men and monoliths alike.'

'We three must be the administrators of the unforeseen, as well as the guardians of this world. Already you have met the Amphibians; you have still to encounter the Silicon-armoured tappers of the lava streams, and the Floaters who are harvesting the sea. Our task is to help them find their full potential – perhaps here, perhaps elsewhere.'
