Chapter Seventeen

With the first comprehensive translation of the handwritten notebook, the paradox was complete. Now there were two consistent and apparently irrefutable bodies of evidence, one proving that the Lunarians must have evolved on Earth, and the other proving that they couldn't have.

All at once the consternation and disputes broke out afresh. Lights burned through the night at Houston and elsewhere as the same inevitable chains of reasoning were reeled out again and yet again, the same arrays of facts scrutinized for new possibilities or interpretations. But always the answers came out the same. Only the notion of the Lunarians having been the product of a parallel line of evolution appeared to have been abandoned permanently; more than enough theories were in circulation already without anyone having to invoke this one. The Navcomms fraternity disintegrated into a myriad of cliques and strays, scurrying about to ally first with this idea and then with that. As the turmoil subsided, the final lines of defense fortified themselves around four main camps.

The Pure Earthists accepted without reservation the deductions from Charlie's diary, and held that the Lunarian civilization had developed on Earth, flourished on Earth, and destroyed itself on Earth and that was that. Thus, all references to Minerva and its alleged civilization were nonsense; there never had been any civilization on Minerva apart from that of the Ganymeans, and that was too far in the remote past to have any bearing on the Lunarian issue. The world depicted on Charlie's maps was Earth, not Minerva, so there had to be a gross error somewhere in the calculations that put it at 250 million miles from the Sun. That this corresponded to the orbital radius of the Asteroids was just coincidence; the Asteroids had always been there, and anything from Iliad that said they hadn't was suspect and needed double-checking.

That left only one question unexplained: Why didn't Charlie's maps look like Earth? To answer this one, the Earthists launched a series of commando raids against the bastions of accepted geological theory and methods of geological dating. Drawing on the hypothesis that continents had been formed initially from a single granitic mass that had been shattered under the weight of immense ice caps and pushed apart by polar material rushing in to fill the gaps, they pointed to the size of the ice caps shown on the maps and stressed how much larger they were than anything previously supposed to have existed on Earth. Now, if in fact the maps showed Earth and not Minerva, that meant that the Ice Age on Earth had been far more severe than previously thought, and its effects on surface geography correspondingly more violent. Add to this the effects of the crustal fractures and vulcanism as described in Charlie's observations of Earth (not Minerva), and there was, perhaps, enough in all that to account for the transformation of Charlie's Earth into modern Earth. So, why were there no traces to be found today of the Lunarian civilization? Answer: It was clear from the maps that most of it had been concentrated on the equatorial belt. Today that region was completely ocean, dense jungle, or drifting desert—adequate to explain the rapid erasure of whatever had been left after the war and the climatic cataclysm.

The Pure Earthist faction attracted mainly physicists and engineers, quite happy to leave the geologists and geographers to worry about the bothersome details. Their main concern was that the sacred principle of the constancy of the velocity of light should not be thrown into the melting pot of suspicion along with everything else.

By entrenching themselves around the idea of Earth origins, the Pure Earthists had moved into the positions previously defended fanatically by the biologists. Now that Danchekker had led the way by introducing his fleet of Ganymean Noah's Arks, the biologists abruptly turned about-face and rallied behind their new assertion of Minervan origin from displaced terrestrial ancestors. What about Charlie's Minerva-Luna flight time and the loop delay around the Annihilator fire-control system? Something was screwed up in the interpretation of Minervan time scales that accounted for both of these. Okay, how could Charlie see Minerva from Luna? Video transmissions. Okay, how could they aim the Annihilator over that distance? They couldn't. The dish at Seltar was only a remote-control tracking station. The weapon itself was mounted in a satellite orbiting Minerva.

The third flag flew over the Cutoff Colony Theory. According to this, an early terrestrial civilization had colonized Minerva, and then declined into a Dark Age during which contact with the colony was lost. The deteriorating conditions of the Ice Age later prompted a recovery on both planets, with the difference that Minerva faced a life-or-death situation and began the struggle to regain the lost knowledge in order that a return to Earth might be made. Earth, however, was going through lean times of its own and, when the advance parties from Minerva eventually made contact, didn't react favorably to the idea of another planetful of mouths to feed. Diplomacy having failed, the Minervans set up an invasion beachhead on Luna. The Annihilator at Seltar had thus been firing at targets on Earth; the translators had been misled by identical place-names on both planets—like Boston, New York, Cambridge, and a hundred other places in the USA, many of the towns on Minerva had been named after places on Earth when the original colony was first established.

The defenders of these arguments drew heavily from the claims of the Pure Earthists to account for the absence of Lunarian relics on Earth. In addition, they produced further support from the unlikely domain of the study of fossil corals in the Pacific. It had been known for a long time that analysis of the daily growth rings of ancient fossil corals provided a measure of how many days there had been in the year at various times in the past, and from this how fast the forces of tidal friction were slowing down the rotation of the Earth about its axis. These researchers showed, for example, that the year of 350 million years ago contained about four hundred days. Ten years previously, work conducted at the Darwin Institute of Oceanography in Australia, using more refined and more accurate techniques, had revealed that the continuity from ancient to modern had not been as smooth as supposed. There was a confused period in the recent past—at about fifty thousand years before—during which the curve was discontinuous, and a comparatively abrupt lengthening in the day had occurred. Furthermore, the rate of deceleration was measurably greater after this discontinuity than it had been before. Nobody knew why this should have happened, but it seemed to indicate a period of violent climatic upheaval, as the corals had taken generations to settle down to a stable growth pattern afterward. The data seemed to indicate that widespread changes had taken place on Earth around this mysterious point in time, probably accompanied by global flooding, and all in all there could be enough behind the story to explain the complete disappearance of any record of the Lunarians' existence.

The fourth main theory was that of the Returning Exiles, which found these attempts to explain the disappearance of the terrestrial Lunarians artificial and inadequate. The basic tenet of this theory was that there could be only one satisfactory reason for the fact that there were no signs of Lunarians on Earth: There had never been any Lunarians on Earth worth talking about. Thus, they had evolved on Minerva as Danchekker maintained and had evolved an advanced civilization, unlike their contemporary brothers on Earth, who remained backward. Eventually, compelled by the Ice Age threat of extinction, the two superpowers of Cerios and Lambia had emerged and begun the race toward the Sun in the way described by Linguistics. Where Linguistics had gone wrong, however, was that by the time of Charlie's narrative, these events were already historical; the goal was already achieved. The Lambians had drawn ahead by a small margin and had already commenced building settlements on Earth, several of them named after their own towns on Minerva. The Cerians followed hard on their heels and established a fire base on Luna, the objective of course being to knock out the Lambian outposts on Earth before moving in themselves.

This theory did not explain the flight time of Charlie's ship, but its supporters attributed the difficulty to unknown differences between Minervan and local (Lunar) dating systems. On the other hand, it required only a few pilot Lambian bases to have been set up on Earth by the time of the war; thus, whatever remained of these after the Cerian assault, could credibly have vanished in fifty thousand years.

And as the battle lines were drawn up and the first ranging shots started whistling up and down the corridors of Navcomms, in no-man's-land sat Hunt. Somehow, he was convinced, everybody was right. He knew the competence of the people around him and had no doubt in their ability to get their figures right. If, after weeks or months of patient effort, one of them pronounced that x was 2, then he was quite prepared to believe that, in all probability, 2 it would turn out to be. Therefore, the paradox had to be an illusion. To try to argue which side was right and which was wrong was missing the whole point. Somewhere in the maze, probably so fundamental that nobody had even thought to question it, there had to be a fallacy—some wrong assumption that seemed so obvious they didn't even realize they were making it. If they could just get back to fundamentals and identify that single fallacy, the paradox would vanish and everything that was being argued would slide smoothly into a consistent, unified whole.
