Rama: The Omnibus

by Arthur C. Clarke

  It had been three days since the missile's existence—and origin—had been announced; all that time, the Hermians had remained stubbornly silent. They could be very good at that, when it suited them.

  Some psychologists had claimed that it was almost impossible to understand fully the mentality of anyone born and bred on Mercury. Forever exiled from Earth by its three-times-more-powerful gravity, Hermians could stand on the Moon and look across the narrow gap to the planet of their ancestors—even of their own parents—but they could never visit it. And so, inevitably, they claimed that they did not want to.

  They pretended to despise the soft rains, the rolling fields, the lakes and seas, the blue skies—all the things that they could know only through recordings. Because their planet was drenched with such solar energy that the daytime temperature often reached six hundred degrees, they affected a rather swaggering roughness that did not bear a moment's serious examination. In fact, they tended to be physically weak, since they could only survive if they were totally insulated from their environment. Even if he could have tolerated the gravity, a Hermian would have been quickly incapacitated by a hot day in any equatorial country on Earth.

  Yet in matters that really counted, they were tough. The psychological pressures of that ravening star so close at hand, the engineering problems of tearing into a stubborn planet and wrenching from it all the necessities of life—these had produced a spartan and in many ways highly admirable culture. You could rely on the Hermians; if they promised something, they would do it—though the bill might be considerable. It was their own joke that, if the sun ever showed signs of going nova, they would contract to get it under control—once the fee had been settled. It was a non-Hermian joke that any child who showed signs of interest in art, philosophy or abstract mathematics was ploughed straight back into the hydroponic farms. As far as criminals and psychopaths were concerned, this was not a joke at all. Crime was one of the luxuries that Mercury could not afford.

  Commander Norton had been to Mercury once, had been enormously impressed—like most visitors—and had acquired many Hermian friends. He had fallen in love with a girl in Port Lucifer, and had even contemplated signing a three-year contract, but parental disapproval of anyone from outside the orbit of Venus had been too strong. It was just as well.

  'Triple A message from Earth, Skipper,' said the bridge. 'Voice and back-up text from Commander-in-Chief. Ready to accept?'

  'Check and file text; let me have the voice.'

  'Here it comes.'

  Admiral Hendrix sounded calm and matter-of-fact, as if he was issuing a routine fleet order, instead of handling a situation unique in the history of space. But then, he was not ten kilometres from the bomb.

  'C-in-C to Commander, Endeavour. This is a quick summary of the situation as we see it now. You know that the General Assembly meets at 14.00 and you'll be listening to the proceedings. It is possible that you may then have to take action immediately, without consultation; hence this briefing.'

  'We've analysed the photos you have sent us; the vehicle is a standard space probe, modified for high-impulse and probably laser-riding for initial boost. Size and mass are consistent with fusion bomb in the 500 to 1,000 megaton range; the Hermians use up to 100 megatons routinely in their mining operations, so they would have had no difficulty in assembling such a warhead.'

  'Our experts also estimate that this would be the minimum size necessary to assure destruction of Rama. If it was detonated against the thinnest part of the shell—underneath the Cylindrical Sea—the hull would be ruptured and the spin of the body would complete its disintegration.'

  'We assume that the Hermians, if they are planning such an act, will give you ample time to get clear. For your information, the gamma-ray flash from such a bomb could be dangerous to you up to a range of a thousand kilometres.'

  'But that is not the most serious danger. The fragments of Rama, weighing tons and spinning off at almost a thousand kilometres an hour, could destroy you at an unlimited distance. We therefore recommend that you proceed along the spin axis, since no fragments will be thrown off in that direction. Ten thousand kilometres should give an adequate safety margin.'

  'This message cannot be intercepted; it is going by multiple-pseudo-random routing, so I can talk in clear English. Your reply may not be secure, so speak with discretion and use code when necessary. I will call you immediately after the General Assembly discussion. Message concluded. C-in-C, out.'

  CHAPTER 38

  GENERAL ASSEMBLY

  ACCORDING TO THE HISTORY books—though no one could really believe it—there had been a time when the old United Nations had 172 members. The United planets had only seven; and that was sometimes bad enough. In order of distance from the Sun, they were Mercury, Earth, Luna, Mars, Ganymede, Titan and Triton.

  The list contained numerous omissions and ambiguities which presumably the future would rectify. Critics never tired of pointing out that most of the United Planets were not planets at all, but satellites. And how ridiculous that the four giants, Jupiter, Saturn, Uranus and Neptune were not included…

  But no one lived on the Gas Giants, and quite possibly no one ever would. The same might be true of the other major absentee, Venus. Even the most enthusiastic of planetary engineers agreed that it would take centuries to tame Venus; meanwhile the Hermians kept their eyes on her, and doubtless brooded over long-range plans.

  Separate representation for Earth and Luna had also been a bone of contention; the other members argued that it put too much power in one corner of the solar system. But there were more people on the Moon than all the other worlds except Earth itself—and it was the meeting place of the UP. Moreover, Earth and Moon hardly ever agreed on anything, so they were not likely to constitute a dangerous bloc.

  Mars held the asteroids in trust—except for the Icarian group (supervised by Mercury) and a handful with perihelions beyond Saturn—and thus claimed by Titan. One day the larger asteroids, such as Pallas, Vesta, Juno and Ceres, would be important enough to have their own ambassadors, and membership of the UP would then reach two figures.

  Ganymede represented not only Jupiter—and therefore more mass than all the rest of the solar system put together—but also the remaining fifty or so Jovian satellites, if one included temporary captures from the asteroid belt (the lawyers were still arguing over this). In the same way, Titan took care of Saturn, its rings and the other thirty-plus satellites.

  The situation for Triton was even more complicated. The large moon of Neptune was the outermost body in the solar system under permanent habitation; as a result, its ambassador wore a considerable number of hats. He represented Uranus and its eight moons (none yet occupied); Neptune and its other three satellites; Pluto and its solitary moon; and lonely, moonless Persephone. If there were planets beyond Persephone, they too would be Triton's responsibility. And as if that was not enough, the Ambassador for the Outer Darkness, as he was sometimes called, had been heard to ask plaintively: 'What about comets?' It was generally felt that this problem could be left for the future to solve.

  And yet, in a very real sense, that future was already here. By some definitions, Rama was a comet; they were the only other visitors from the interstellar deeps, and many had travelled on hyperbolic orbits even closer to the Sun than Rama's. Any space-lawyer could make a very good case out of that—and the Hermian Ambassador was one of the best.

  'We recognize His Excellency the Ambassador for Mercury.'

  As the delegates were arranged counter-clockwise in order of distance from the sun, the Hermian was on the President's extreme right. Up to the very last minute, he had been interfacing with his computer; now he removed the synchronizing spectacles which allowed no one else to read the message on the display screen. He picked up his sheaf of notes, and rose briskly to his feet.

  'Mr. President, distinguished fellow delegates, I would like to begin with a brief summary of the situation which now confronts us.'

  From
some delegates, that phrase 'a brief summary' would have evoked silent groans among all listeners; but everyone knew that Hermians meant exactly what they said.

  'The giant spaceship, or artificial asteroid, which has been christened Rama was detected over a year ago, in the region beyond Jupiter. At first it was believed to be a natural body, moving on a hyperbolic orbit which would take it round the sun and on to the stars.'

  'When its true nature was discovered, the Solar Survey Vessel Endeavour was ordered to rendezvous with it. I am sure we will all congratulate Commander Norton and his crew for the efficient way in which they have carried out their unique assignment.'

  'At first, it was believed that Rama was dead—frozen for so many hundreds of thousands of years that there was no possibility of revival. This may still be true, in a strictly biological sense. There seems general agreement, among those who have studied the matter, that no living organism of any complexity can survive more than a very few centuries of suspended animation. Even at absolute zero, residual quantum effects eventually erase too much cellular information to make revival possible. It therefore appeared that, although Rama was of enormous archaeological importance, it did not present any major astropolitical problems.'

  'It is now obvious that this was a very naïve attitude, though even from the first there were some who pointed out that Rama was too precisely aimed at the Sun for pure chance to be involved.'

  'Even so, it might have been argued—indeed, it was argued—that here was an experiment that had failed. Rama had reached the intended target, but the controlling intelligence had not survived. This view also seems very simple-minded; it surely underestimates the entities we are dealing with.'

  'What we failed to take into account was the possibility of non-biological survival. If we accept Dr. Perera's very plausible theory, which certainly fits all the facts, the creatures who have been observed inside Rama did not exist until a short time ago. Their patterns, or templates, were stored in some central information bank, and when the time was ripe they were manufactured from available raw materials—presumably the metallo-organic soup of the Cylindrical Sea. Such a feat is still somewhat beyond our own ability, but does not present any theoretical problems. We know that solid-state circuits, unlike living matter, can store information without loss, for indefinite periods of time.'

  'So Rama is now in full operating condition, serving the purpose of its builders—whoever they may be. From our point of view, it does not matter if the Ramans themselves have all been dead for a million years, or whether they too will be re-created, to join their servants, at any moment. With or without them, their will is being done and will continue to be done.'

  'Rama has now given proof that its propulsion system is still operating. In a few days, it will be at perihelion, where it would logically make any major orbit change. We may therefore soon have a new planet—moving through the solar space over which my government has jurisdiction. Or it may, of course, make additional changes and occupy a final orbit at any distance from the sun. It could even become a satellite of a major planet—such as Earth…'

  'We are therefore, fellow delegates, faced with a whole spectrum of possibilities, some of them very serious indeed. It is foolish to pretend that these creatures must be benevolent and will not interfere with us in any way. If they come to our solar system, they need something from it. Even if it is only scientific knowledge—consider how that knowledge may be used.'

  'What confronts us now is a technology hundreds, perhaps thousands, of years in advance of ours, and a culture which may have no points of contact whatsoever. We have been studying the behaviour of the biological robots—the biots—inside Rama, as shown on the films that Commander Norton has relayed, and we have arrived at certain conclusions which we wish to pass on to you.'

  'On Mercury we are perhaps unlucky in having no indigenous life forms to observe. But, of course, we have a complete record of terrestrial zoology, and we find in it one striking parallel with Rama.'

  'This is the termite colony. Like Rama, it is an artificial world with a controlled environment. Like Rama, its functioning depends upon a whole series of specialized biological machines: workers, builders, farmers—warriors. And although we do not know if Rama has a queen, I suggest that the island known as New York serves a similar function.'

  'Now, it would obviously be absurd to press this analogy too far; it breaks down at many points. But I put it to you for this reason: What degree of cooperation or understanding would ever be possible between human beings and termites? When there is no conflict of interest, we tolerate each other. But when either needs the other's territory or resources, no quarter is given.'

  'Thanks to our technology and our intelligence, we can always win, if we are sufficiently determined. But sometimes it is not easy, and there are those who believe that, in the long run, final victory may yet go to the termites…'

  'With this in mind, consider now the appalling threat that Rama may—I do not say must—present to human civilization. What steps have we taken to counter it, if the worst eventuality should occur? None whatsoever; we have merely talked and speculated and written learned papers.'

  'Well, my fellow delegates, Mercury has done more than this. Acting under the provisions of Clause 34 of the Space Treaty of 2057, which entitled us to take any steps necessary to protect the integrity of our solar space, we have dispatched a high-energy nuclear device to Rama. We will indeed be happy if we never have to utilize it. But now, at least, we are not helpless—as we were before.'

  'It may be argued that we have acted unilaterally, without prior consultation. We admit that. But does anyone here imagine—with, all respect, Mister President—that we could have secured any such agreement in the time available? We consider that we are acting not only for ourselves, but for the whole human race. All future generations may one day thank us for our foresight.'

  'We recognized that it would be a tragedy—even a crime—to destroy an artifact as wonderful as Rama. If there is any way in which this can be avoided, without risk to humanity, we will be very happy to hear of it. We have not found one, and time is running out.'

  'Within the next few days, before Rama reaches perihelion, the choice will have to be made. We will, of course, give ample warning to Endeavour—but we would advise Commander Norton always to be ready to leave at an hour's notice. It is conceivable that Rama may undergo further dramatic transformations at any moment.'

  'That is all, Mister President, fellow delegates. I thank you for your attention. I look forward to your cooperation.'

  CHAPTER 39

  COMMAND DECISION

  'WELL, ROD, how do the Hermians fit into your theology?'

  'Only too well, Commander,' replied Rodrigo with a humourless smile. 'It's the age-old conflict between the forces of good and the forces of evil. And there are times when men have to take sides in such a conflict.'

  I thought it would be something like that, Norton told himself. This situation must have been a shock to Boris, but he would not have resigned himself to passive acquiescence. The Cosmo-Christers were very energetic, competent people. Indeed, in some ways they were remarkably like the Hermians.

  'I take it you have a plan, Rod.'

  'Yes, Commander. It's really quite simple. We merely have to disable the bomb.'

  'Oh. And how do you propose to do that?'

  'With a small pair of wire-cutters.'

  If this had been anyone else, Norton would have assumed that they were joking. But not Boris Rodrigo.

  'Now just a minute! It's bristling with cameras. Do you suppose the Hermians will just sit and watch you?'

  'Of course; that's all they can do. When the signal reaches them, it will be far too late. I can easily finish the job in ten minutes.'

  'I see. They certainly will be mad. But suppose the bomb is booby-trapped so that interference sets it off?'

  'That seems very unlikely; what would be the purpose? This bomb was built for a specific deep-spa
ce mission, and it will be fitted with all sorts of safety devices to prevent detonation except on a positive command. But that's a risk I'm prepared to take—and it can be done without endangering the ship. I've worked everything out.'

  'I'm sure you have,' said Norton. The idea was fascinating—almost seductive in its appeal; he particularly liked the idea of the frustrated Hermians; and would give a good deal to see their reactions when they realized—too late—what was happening to their deadly toy.

  But there were other complications, and they seemed to multiply as Norton surveyed the problem. He was facing by far the most difficult, and the most crucial, decision in his entire career.

  And that was a ridiculous understatement. He was faced with the most difficult decision any commander had ever had to make; the future of the entire human race might well depend upon It. For just suppose the Hermians were right?

  When Rodrigo had left, he switched on the DO NOT DISTURB sign; he could not remember when he had last used it, and was mildly surprised that it was working. Now, in the heart of his crowded, busy ship, he was completely alone—except for the portrait of Captain James Cook, gazing at him down the corridors of time.

  It was impossible to consult with Earth; he had already been warned that any messages might be tapped—perhaps by relay devices on the bomb itself. That left the whole responsibility in his hands.

  There was a story he had heard somewhere about a President of the United States—was it Roosevelt or Pérez?—who had a sign on his desk saying 'The buck stops here'. Norton was not quite certain what a buck was, but he knew when one had stopped at his desk.

  He could do nothing, and wait until the Hermians advised him to leave. How would that look in the histories of the future? Norton was not greatly concerned with posthumous fame or infamy, yet he would not care to be remembered for ever as the accessory to a cosmic crime—which it had been in his power to prevent.
