Inherit the Stars

by James P. Hogan

  On Day Eighteen, the departure from the dome was recorded as follows: Formed up in two columns of vehicles. Ours moved out half an hour ahead of the second as a small advanced scouting group. We reached a ridge about three miles from the dome and could see the main column finish loading and begin lining up. That was when the missiles hit. The first salvo caught them all out in the open. They didn't have a chance. We trained our receivers on the area for a while, but there was nothing. The only way we'll ever get off this death furnace is if there are ships left at Gorda. As far as I know, there are 340 of us, including over a hundred girls. The column comprises five scout cars, eight tracked trucks, and ten heavy tanks. It will be a grim journey. Even Koriel isn't taking bets on how many get there.

  Minerva is just a black, smoky ball, difficult to pick out against the sky. Two of the red spots have joined up to form a line stretching at an angle across the equator. Must be hundreds of miles long. Another red line is growing to the north. Every now and then, parts of them glow orange through the smoke clouds for a few hours and then die down again. Must be a mess there.

  The column moved slowly through the desert of scorched gray dust, and its numbers shrank rapidly as wounds and radiation sickness took their toll. On Day Twenty-six they encountered a Lambian ground force and for three hours fought furiously among the crags and boulders. The battle ended when the remaining Lambian tanks broke cover and charged straight into the Cerian position, only to be destroyed right on the perimeter line by Cerian women firing laser artillery at point-blank range. After the battle there were 165 Cerians left, but not enough vehicles to carry them.

  After conferring, the Cerian officers devised a plan to continue the journey leapfrog fashion. Half the company would be moved half a day's distance forward and left there with one truck to use as living accommodation, while the remaining vehicles returned to collect the group left behind. So it would go on all the way to Gorda. Charlie and Koriel were among the first group lifted on ahead.

  Day Twenty-eight. Uneventful drive. Set up camp in a shady gorge and watched the convoy about-face again and begin its long haul back for the others. They should be back this time tomorrow. Nothing much to do until then. Two died on the drive, so there are fifty-eight of us here. We take turns to rest and eat inside the truck. When it's not your turn, you make yourself as comfortable as you can sitting among the rocks. Koriel is furious. He's just spent two hours sitting outside with four of the artillery girls. He says whoever designed space suits should have thought of situations like that.

  The convoy never returned.

  Using the single remaining truck, the group continued the same tactic as before, ferrying one party on ahead, dumping them, and returning for the rest. By Day Thirty-three, sickness, mishaps, and one suicide had depleted the numbers such that all the survivors could be carried in the truck at once, so the leapfrogging was discontinued. Driving steadily, they estimated they would reach Gorda on Day Thirty-eight. On Day Thirty-seven, the truck broke down. The spare parts needed to repair it were not available.

  Many were weak. It was clear that an attempt to reach Gorda on foot would be so slow that nobody would make it.

  Day Thirty-seven. Seven of us—four men (myself, Koriel, and two of the combat troopers) and three girls—are going to make a dash for Gorda while the others stay put in the truck and wait for a rescue party. Koriel is cooking a meal before we set out. He has been saying what he thinks of life in the infantry—doesn't seem to think much of it at all.

  Some hours after they left the truck, one of the troopers climbed a crag to survey the route ahead. He slipped, gashed his suit, and died instantly from explosive decompression. Later on, one of the girls hurt her leg and lagged farther and farther behind as the pain worsened. The Sun was sinking and there was no time for slowing down. Everybody in the group wrestled with the same equation in his mind—one life or twenty-eight?—but said nothing. She solved the problem for them by quietly closing her air valve when they stopped to rest.

  Day Thirty-eight. Just Koriel and me now—like the old days. The trooper suddenly doubled up, vomiting violently inside his helmet. We stood and watched while he died, and could do nothing. Some hours later, one of the girls collapsed and said she couldn't go on. The other insisted on staying with her until we send help from Gorda. Couldn't really argue—they were sisters. That was some time ago. We've stopped for a breather; I am getting near my limit. Koriel is pacing up and down impatiently and wants to get moving. That man has the strength of twelve [?lions?].

  Later. Stopped at last for a couple of hours sleep. I'm sure Koriel is a robot—just keeps going and going. Human tank. Sun very low in sky. Must make Gorda before Lunar night sets in.

  Day Thirty-nine. Woke up freezing cold. Had to turn suit heating up to maximum—still doesn't feel right. Think it's developing a fault. Koriel says I worry too much. Time to be on the move again. Feel stiff all over. Seriously wondering if I'll make it. Haven't said so.

  Later. The march has been a nightmare. Kept falling down. Koriel insisted that the only chance we had was to climb up out of the valley we were in and try a short-cut over a high ridge. I made it about halfway up the cleft leading toward the ridge. Every step up the cleft I could see Minerva sitting right over the middle of the ridge, gashes of orange and red all over it, like a (macabre?) face, taunting. Then I collapsed. When I came to, Koriel had dragged me inside a pilot digging of some sort. Maybe someone was going to put an outpost of Gorda here. That was a while ago now. Koriel has gone on and says help will be back before I know it. Getting colder all the time. Feet numb and hands stiff. Frost starting to form in helmet—difficult to see.

  Thinking about all the people strung out back there with night coming down, all like me, wondering if they'll be picked up. If we can hold out we'll be all right. Koriel will make it. If it were a thousand miles to Gorda, Koriel would make it.

  Thinking about what has happened on Minerva and wondering if, after all this, our children will live on a sunnier world—and if they do, if they will ever know what we did.

  Thinking about things I've never really thought about before. There should be better ways for people to spend their lives than in factories, mines, and army camps. Can't think what, though—that's all we've ever known. But if there is warmth and color and light somewhere in this Universe, then maybe something worthwhile will come out of what we've been through.

  Too much thinking for one day. Must sleep for a while now.

  Hunt found he had read right through to the end, absorbed in the pathos of those final days. His voice had fallen to a sober pitch. A long silence ensued.

  "Well, that's it," he concluded, a little more briskly. "Did you notice that bit right at the end? In the last few lines he was talking about seeing the surface of Minerva again. Now, they might have used telescopes earlier on, but in the situation he was in there, they'd hardly be lugging half an observatory along with them, would they?"

  Maddson's assistant looked thoughtful. "How about that periscope video gadget that was in the helmet?" he suggested. "Maybe there's something wrong in the translation. Couldn't he be talking about seeing a transmission through that?"

  Hunt shook his head. "Can't see it. I've heard of people watching TV in all sorts of funny places, but never halfway up a bloody mountain. And another thing: He described it as sitting up above the ridge. That implies it's really out there. If it were a view on video, he'd never have worded it that way. Right, Don?"

  Maddson nodded wearily. "Guess so," he said. "So, where do we go from here?"

  Hunt looked from Maddson to the assistant and back again. He leaned his elbows on the edge of the table and rubbed his face and eyeballs with his fingers. Then he sighed and sat back.

  "What do we know for sure?" he asked at last. "We know that those Lunarian spaceships got to our Moon in under two days. We know that they could accurately aim a weapon, sited on our Moon, at a Minervan target. We also know that the round trip for electromagnetic waves w
as much shorter than it could possibly have been talking about the right place. Finally, we can't prove but we think that Charlie could stand on our Moon and see quite clearly the surface features of Minerva. Well, what does that add up to?"

  "There's only one place in the Universe that fits all those numbers," Maddson said numbly.

  "Exactly—and we're standing on it! Maybe there was a planet called Minerva outside Mars, and maybe it had a civilization on it. Maybe the Ganymeans took a few animals there and maybe they didn't. But it doesn't really matter anymore, does it? Because the only planet Charlie's ship could possibly have taken off from, and the only planet they could have aimed that Annihilator at, and the only planet he could have seen in detail from Luna—is this one!

  "They were from Earth all along!

  "Everyone will be jumping off the roof and out of every window in the building when this gets around Navcomms."

  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.
