Part 23 (1/2)

'My dear Jefferies, there's always evidence. I beg you not to afflict me with evidence! There's evidence for Atlantis and for Noah's flood and for fairies and for unidentified flying objects, and for a thousand impossibilities ... Are not these absurd beliefs merely unwitting admissions that our own consciousness is so circ.u.mscribed we desire to extend it through other means? Weren't the G.o.ds of the original Greek Olympus one such example, cooked up, as it were, to explain the inexplicable? I suspect that the universe, and the universes surrounding it, are really very simply comprehended, had we wit enough to manage the task.'

'We have wit enough. Our ascendancy over past centuries shows it.'

'You think so? What a comfortable lack of humility you do exhibit, Jefferies! I know you seek to do good, but heaven preserve us from those who mean well. Charles Darwin, a sensible man, admitted that the minds of mankind had evolved - if I recall his words correctly - from a mind as low as that of the lowest animal.'

Attempting a laugh, I said, 'The operative word there is evolved. The sum is continually ever greater than its parts. Give us credit, we are trying to exceed our limitations and to comprehend the universe. We'll get there one day.'

'I do not share your optimism. We have made no progress in our understanding of that curious continuity that we term life and death since - well, let's say, to be specific, because specificity is generally conceded to be desirable -since the Venerable Bede wrote his Ecclesiastical History Ecclesiastical History some time in the seventh century. I trust you are familiar with this work?' some time in the seventh century. I trust you are familiar with this work?'

'No. I've not heard of the book.'

'The news has been slow to reach you, n'est ce pas? Let me quote, from my all too fallible memory, the Venerable Bede's reflections on those grand questions we have been discussing. He says something to this effect. ”When compared with the stretch of time unknown to us, O king, the present life of men on Earth is like the flight of a solitary sparrow through the hall where you and your companions sit in winter. Entering by one high window and leaving by another, while it is inside the hastening bird is safe from the wintery storm. But this brief moment of calm is over in a moment. It returns to the winter whence it came, vanis.h.i.+ng for ever from your sight. Such too is man's life. Of what follows, of what went before, we are utterly ignorant.”'

Sighing, I told Bateson I must return to my work.

As I walked away, he called to me, so that I turned back.

'You know what the temperature is out there, Jefferies?' He indicated the surface of Mars with a pale fluttering hand. 'I understand it's round about minus 76 degrees Celsius. Even colder than a dead body in its earthly grave! Nothing mankind could do would warm that ground up to comfortable temperate zone temperatures, eh? Do you imagine any great work of art, any musical composition, was ever created at minus 76 Celsius?'

'We must set a precedent, John,' I told him.

I left him alone on the upper gallery, gazing at the bleached landscape outside.

The R&A Hospital

On the following day, when I was resting, Dayo came to visit me again. He tried to persuade me to see what 'the computer people', as he called them, were doing. I could not resist his blandishments for ever, and got myself up.

Going with him to the control room, I found that Dayo was popular there too. He had been learning to work on the big quantputer with the mainly American contingent who staffed the machines. The striking patterns on his tiles for the Lower Ground had been devised using it.

The mainframe had originally been programmed to handle the running of the Martian outpost - its humidity, atmospheric pressure, chemical contents, temperature levels and so forth. Now all these factors were being handled by a single rejigged laptop quantputer.

I was astonished, but the bearded Steve Rollins, the man in charge of the programme under Arnold Poulsen, explained they had evolved a formula whereby interrelated factors could all be grouped under one easily computable formula. Our survival and comfort were being controlled by the laptop. The change-over had taken place at the 'X' hour, during a night some five months previously. No one had noticed a shade of difference, while the big mainframe had been freed for more ambitious things.

And what things! I had wondered why the control staff took so little interest in our forums and the Utopian society. Here was the answer: they had been otherwise engaged.

At Dayo's prompting, Steve showed me the programme they were running. He spoke in an easy drawl.

'You may think this is unorthodox use of equipment,'

Steve said, stroking his whiskers with a gesture he had and grinning at me. 'But as that great old musician, Count Basie, said, ”You just gotta keep on keeping on”. If you regard science as a duel with nature, you must never drop your guard. Stuck here on this Ayers Rock in the sky, we must keep on keeping on or we stagnate. Guess you know that.'

'Guess I do.'

'As a kid I used to play a game called Sim Galaxy on my old computer. It produced simulations of real phenomena, from people to planetary systems. If you kept at it long enough, fighting entropy and natural disasters, it was possible to get to rule over a populated galaxy.'

Steve said that his team had adapted a more modest version of the game, into which they had fed all the quantputer records, sedulously kept, of every person and event on Mars. The simulation had become more and more accurate as the programme was refined. Every detail of our Mars habitation, every detail of each person in the habitation, was precisely represented in the simulation. They called the programme Sim White Mars.

We watched on a widescreen monitor. There people lived and moved and had their being. Our small Martian world was totally emulated; the one item missing was Olympus, a being as yet incomputable.

I fought against the suspicion that this was not a true emulation but a trick, until Steve mentioned casually that they were using a new modified quantputer that computed faster, fuzzier, than the old conventional quantputer - certainly than any of the quantcomps people carry around with them.

The scale of the thing made me feel dizzy. Dayo was immediately at hand, fetching me a stool.

In full colour, recognisable people went about their business, around the settlement and in the laboratory. They seemed to move in real time.

The scene flipped to a schoolroom, where Belle Rivers was talking with a jeuwu cla.s.s of ten children. Steve moved a pointer on to Belle, touched a key, and at once a scroll of characteristics came up: Belle's birth date and place, her entire CV and many other details. They flashed on the screen and were gone at another touch of a key.

'We call these simulated objects and people emulations, they are so precise,' said Steve. 'To them, their world is perfectly real. They sure think and act like real.'

'But they are mere electronic images. They can't be said to think.'

Steve laughed. 'Guess they don't realise they're just a sequence of numbers and colours in a computer, if that's what you mean.' He added, in lower key, 'How often do we realise we're also just a sequence in another key?'

I said nothing.

The people on screen were now gathering in the main thoroughfare. This was recognisably the day the third marathon was held. There were the runners, many with false wings attached to them. There were the officials who ran the race. There were the crowds.

A whistle blew and the runners started forward, struggling for s.p.a.ce, so closely were they packed, even as they had done weeks previously.

'All this takes real heavy puting power, even using the quantputer,' Steve said. 'That's why we are running some weeks behind real time. We're working on that problem.' The runners began to trot, jostling closely for position. 'I guess we'll catch up eventually.'

'Want to bet on who will win?' Dayo asked mischievously.

'You see this is a kind of rerun of the marathon,' Steve said. 'And now, I just tap on a couple of keys...'

He did so. The screen was filled with phantom creatures, grey skeletons with strange pumping spindles instead of legs, naked domes for heads, their teeth large and bared. The inhuman things pressed onwards, soundless, joyless ... The Race of Death, I thought.

'We got the X-ray stuff off the hospital,' Steve said. 'It's spare diagnostic equipment...'

The skeletons streamed on, with ghostly grey buildings as background, racing through their silent transparent world.

Steve tapped his keyboard once more and the world on the screen became again the one we recognised as ours.

With a flash of humour, he said, 'You have your Utopia, Tom. This is our baby. How do you like it?'

'But in the wrong hands...' I began. A feeling of nausea silenced me.

Dayo took my arm. 'I want you to watch yourself as an emulation, Tom. Please, Steve...'

Steve touched a couple of keys on his keyboard. The scene changed. An office block along the marathon course came into focus. Moving through the window, the emulation picked out a man and two women, standing close together, watching the runners pa.s.s their building. I recognised Cang Hai, Mary Fangold and myself.

My emulation clutched his head and went to the back of the room to sit on a sofa. Cang Hai came over to it and stood there in silence, looking down at its - my - bowed head. After a moment, I stirred myself, smiled weakly at Cang Hai, rose, and returned to the window to watch the runners.

'I don't remember doing that,' I said.
