"Inherit the Stars"

A classic SF/mystery story that shows its age somewhat. James P. Hogan really loves describing the nitty-gritty of all those communication systems.

• Like Hunt, he had survived the mine field of the age of unreason and emerged safe and single into his mid-thirties. With Hunt, he shared a passion for work, a healthy partiality for most of the deadly sins to counterbalance it, and his address book.
• Among the ceaseless stream of binary data that flowed through its antennae, it identified a call from the Boeing’s Gamma Nine master computer, requesting details of the latest weather forecast for northern California. Sirius Fourteen flashed the message to Sirius Twelve, hanging high over the Canadian Rockies, and Twelve in turn beamed it down to the tracking station at Edmonton. From here the message was relayed by optical cable to Vancouver Control and from there by microwave repeaters to the Weather Bureau station at Seattle.
• All living organisms take into their bodies known proportions of the radioactive isotopes of carbon and certain other elements. During life, an organism maintains a constant ratio of these isotopes to “normal” ones, but when it dies and intake ceases, the active isotopes are left to decay in a predictable pattern. This mechanism provides, in effect, a highly reliable clock, which begins to run at the moment of death.
• All the established rules and principles dictated that the appearance of two identical end products from two completely isolated families of evolution, unfolding independently in different corners of the universe, just couldn’t happen. Hence, if Charlie came from somewhere else, a whole branch of accepted scientific theory would come crashing down in ruins. So-Charlie couldn’t possibly have come from Earth.
• “Built-in antiglare,” Gray observed. <> “The visor is fabricated from a self-polarizing crystal,”
• They minded even less when she began turning up with some of the other girls from Naycomms in tow, adding a refreshing party atmosphere to the whole proceedings. This development met with the full approval of the visitors from out-of-town; however, it had led to somewhat strained relationships on the domestic front for one or two of the locals.
• The arrangement of internal organs leaves much to be desired, owing to our inheriting a system originally developed to suit a horizontal and not an upright posture. In our respiratory system, for example, we find that the wastes and dirt that accumulate in the throat and nasal regions drain inside and not outside, as happened originally, a prime cause of many bronchial and chest complaints not suffered by four-footed animals.
• “It’s from one of the pocket books,” Hunt replied. “I think the book is something not unlike a diary. I also believe that that”-he pointed at the sheet-“could well be a calendar.” He caught a sly wink from Lyn Garland and returned it.
• “Exactly. This is just the sort of juggling you have to do to get a sensible fit of our months into our year. It happens because there’s no simple relationship between the orbital periods of planet and satellite; there’s no reason why there should be. I’m guessing that if this is a calendar that relates to some other planet,
• nobody had told them about the tables the Mathematics section thought might be mass-unit conversion factors. Maybe one of the other tables did the same thing for units of length and distance? If so, and if they could find a reference to Charlie’s height among his papers, the simple process of measuring him would allow them to work out how many Earth meters there were in a Lunarian mile. Since they abeady had a figure for the planet’s surface gravity, its mass and mean density should follow immediately.
• “Out -out to the stars! We’re on our way to the stars over here! It started when Danchekker’s fish first crawled up out of the mud. The urge that made them do it is the same as the one that’s driven you all your life. You’ve gone inside the atom as far as you can go; there’s only one way left now-out. That’s what UNSA has to offer that you can’t refuse.”
• Hunt had the fleeting thought that had Caldwell been born three thousand years previously, Rome might well have been built in a day.
• (b) Class II Exceptions Differing from Class I in irradiation history, formation of glasses, absence of impact corroboration and positive results to tests for elements hyperium, bonnevilliuin, genevium. Example: Crater Lunar Catalogue reference MB 3O76/K2/E
  currently classed as meteoritic. Classification erroneous. Crater MB 3076/K2/E was made by a nucleonic bomb. Other cases confirmed.
• A tenth planet, christened Minerva after the Roman goddess of wisdom, is now known to have existed approximately 250 million miles from the Sun between the orbits of Mars and Jupiter, in the position now occupied by the Asteroid Belt, and is firmly established as having been the center of the Lunarian civilization.
• The stream of data taken in by the cameras flashed back to preprocessors in the low-level control room, and from there via cable to the surface of Ganymede. After encoding by the computers in the Site Operations Control building, it was relayed by microwave repeaters seven hundred miles to Ganymede Main Base, restored to full strength, and redirected up to the orbiting command ship. Here, the message was fed into the message exchange and scheduling processor complex, transformed into high-power laser modulations, and slotted into the main outgoing signal beam to Earth. For over an hour the data streaked across the Solar System,
• To the still unresolved question of whether the Lunarians and the Minervans had been one and the same or not, there was immediately added the further riddle: Where had the Ganymeans come from, and had they any connection with either? One bemused UNSA scientist summed up the situation by declaring that it was about time UNSA established an Alien Civilizations Division to sort out the whole damn mess!
• “It is not obvious at first sight,” Danchekker replied, “but by detailed comparison it is possible to relate the structure of that fish, bone for bone, to that of the Ganymean skeleton. They’re both from the same evolutionary line.” <> “That fish is one of those that were found on the Lunarian base on Farside,” Hunt said suddenly... All that was wrong with the earlier assumption was our failure to appreciate the gap in time between the presence of the Ganymeans on Minerva, and that of the Lunarians.”
• There are no traces of their civilization to be found on Earth, because it never existed on Earth-but neither was it the product of any parallel process of evolution. The Lunarian civilization developed independently on Minerva from the same ancestral stock as we did and all other terrestrial vertebrates-from ancestors that were transported to Minerva, twenty-five million years ago, by the Ganymeans!”
• The trail behind this rapid succession of new developments was by this time littered with the abandoned carcases of dead ideas.
• 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.
• 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,
• Strange emotions welled inside him as he stared at the spot where, millennia before the first page of history had been written, a huddled figure had painfully scrawled the last page of a story that Hunt had read so recently in an office in Houston, a quarter of a million miles away. He thought of the time that had passed since those events had taken place-of the empires that had grown and fallen, the cities that had crumbled to dust, and the lives that had sparkled briefly and been swallowed into the past-while all that time, unchanging, the secret of these rocks had lain undisturbed.
• Now they depended utterly for survival on the skills of those who had designed and built the ship. The green hills and blue skies of Earth were no longer factors of survival and seemed to shed some of their tangible attributes, almost like the aftermath of a dream that had seemed real. Hunt came to think of reality as a relative quantity-not something absolute that can be left for a while and then returned to. The ship became the only reality; it was the things left behind that ceased, temporarily, to exist.
• I like your idea that the Lunarians evolved on Minerva from terrestrial animal species that the Ganymeans imported. It’s the only thing that accounts acceptably for no traces of any civilization showing up on Earth.
• it all adds up to a very peculiar thing: ‘Manlike’ and ‘dry-land’ became synonymous on Minerva because they did in fact mean the same thing. All the land animals on Minerva were new models. We coined the word terrestoid to describe them in English.” <> “All of them? You mean that by Charlie’s time there were none of the original Minervan species left at all?”
• “Any air-breathing life form that evolved from the same primitive ancestors as this fish and inherited the same fundamental system of microchemistry, would be extremely susceptible to a family of toxins that includes carbon dioxide-far more so than the majority of terrestrial species.” <> For once, everything added up. About twenty-five million years ago, the concentration of carbon dioxide in the atmosphere of Minerva apparently increased suddenly, possibly through some natural cause that had liberated the gas from chemical combination in rocks, or possibly as a result of something the Ganymeans had done. This could also explain why the Ganymeans had brought in all the animals. Perhaps their prime objective had been to redress the balance... The native life succumbed, and the more highly resistant immigrants flourished and spread out over a whole new world denuded of alien competition.
• at least one chapter in the early history of Minerva had been cleared up. Everything now pointed to the Lunarians and their civilization as having developed on Minerva and not on Earth. It explained the failure of Schorn’s early attempt to fix the length of the day in Hunt’s calendar by calculating Charlie’s natural periods of sleep and wakefulness. The ancestors of the Lunarians had arrived from Earth carrying a deeply rooted metabolic rhythm evolved around a twenty-four-hour cycle. {???}
• How could he manipulate into being a situation in which the things they had in common outweighed their differences? Well, what did they have in common? Starting with the simplest and most obvious thing-they were both human beings from planet Earth. So where would this fundamental truth come to totally overshadow anything else? <> Where but on the barren wastes of the Moon or a hundred million miles out in the emptiness of space?
• “The walls of those outer casings are sixteen feet thick,” he informed them. “They’re made from an alloy that would cut tungsten-carbide steel like cream cheese. The mass concentration inside them is phenomenal. We think they provided closed paths in which masses of highly concentrated matter were constrained in circulating or oscillating resonance, interacting with strong fields. It’s possible that the high rates of change of gravity potential that this produced were somehow harnessed to induce a controlled distortion in the space around the ship. In other words, it moved by continuously falling into a hole that it created in front of itself-kind of like a four-dimensional tank track.” <> “You mean it trapped itself inside a space-time bubble, which propagated somehow through normal space?” somebody offered.
• And beyond every new world, another beckoned. And always the faces around him were unfamiliar ones-they drifted into his life like the transient shadows of the rocks that now moved toward him from the mists ahead. Like the rocks, for a while the people seemed to exist and take on form and substance, before slipping by to dissolve into the shrouds of the past behind him, as if they had never been.
• Above him, five times larger than the Moon seen from Earth, was the full disk of Jupiter. <> No photograph he had ever seen, or any image reproduced on a display screen, could compare with the grandeur of that sight. It filled the sky with its radiance. All the colors of the rainbow were woven into its iridescent bands of light, stacked layer upon layer outwards from its equator. They faded as they approached its edge and merged into a hazy circle of pink that encircled the planet. The pink turned to violet and finally to purple, ending in a clear, sharp outline that traced an enormous circle against the sky. Immutable, immovable, eternal… mightiest of the gods-and tiny, puny, ephemeral man had crawled on a pilgrimage of five hundred million miles to pay homage.
• That this requirement was evidently met could suggest that relative to its size, the crust of Minerva was exceptionally thin, and the structure of this crust unstable. This is significant, as becomes clear later. Fuller’s model also ties in with the latest information from the Asteroid surveys. The thin crust could be the result of relatively rapid surface cooling caused by the vast distance from the Sun, but with the internal molten condition being prolonged by heat sources below the surface.
• Many fossil finds have been made on Earth of creatures that represented various branches of development from the early progressive apes in the general direction of man. All finds to date, however, have been classed as belonging to offshoots from the main stream; a specimen of a direct link in the chain leading to Homo sapiens has always persistently eluded us.
• Minerva exploded and dispersed to become the Asteroid Belt. The greater part of its mass, we’re fairly sure, was thrown into the outer regions of the Solar System and became Pluto. Its moon, although somewhat shaken, was left intact. During the gravitational upheaval that occurred when its parent planet broke up, the sateffite’s orbital momentum around the Sun was reduced and it began to fall inward.
• “We can’t tell how long the orphaned moon plunged steadily nearer the Sun. Maybe the trip lasted months, maybe years. Next comes one of those million-to-one chances that sometimes happen in nature.
• The trajectory followed by the moon brought it close to Earth, which had been pursuing its own solitary path around the Sun ever since the beginning of time!” ... until this point in time, some fifty thousand years ago, planet Earth had no moon! The two bodies drew close enough for their gravitational fields to interact to the point of mutual capture; the new, common orbit turned out to be stable, and Earth adopted a foundling it has kept right up to this day.
• “But why speculate? What’s the point in saying they should have diverged, when it’s clear that they didn’t?” <> Danchekker beamed and showed his teeth. “What makes you say they didn’t?” he challenged.
• Danchekker straightened up and regarded the room with an unblinking stare. “Now perhaps you see the point of all this. I am stating that, on the evidence we have just examined, the human race did not evolve on Earth at all. It evolved on Minerva!”
• Man, on the other hand, does not know how to give in. He is capable of summoning up reserves of stubbornness and resilience that are without parallel on his planet. He is able to attack anything that threatens his survival, with an aggressiveness the like of which the Earth has never seen otherwise. It is this that has enabled him to sweep all before him, made him lord of all the beasts, helped him tame the winds, the rivers, the tides, and even the power of the Sun itself.
• “Well, where did it come from? It seems out of character with the sedate and easygoing pattern of evolution on Earth. Now we see where it came from: It appeared as a mutation among the evolving primates that were isolated on Minerva. It was transmitted through the population there until it became a racial characteristic... “That same driving force we see in man today. Man has proved invincible in every challenge that the Universe has thrown at him.
