"Just think of it, Vic, another day and we’ll be there. Animals that actually walked the Earth twenty-five million years ago! Any biologist would give his right arm for an experience like this." He held up the folder. "Look at that. I do believe it to be a perfectly preserved example of Trilophodon-a four-tusked Miocene mammoth over fifteen feet high. Can you imagine anything more exciting than that?"
Hunt scowled sourly across the room at the collection of pin-ups adorning the far wall, bequeathed by an earlier UNSA occupant.
"Frankly, yes," he muttered. "But equipped rather differently than a bloody Trilophodon."
"Eh? What’s that you said?" Danchekker blinked uncomprehendingly through his spectacles.
Hunt reached for his cigarette case. "It doesn’t matter, Chris," he sighed.
Chapter Twenty-Two
The flight northward to Pithead lasted just under two hours. On arrival, the group from Earth assembled in the officers’ mess of the control building for coffee, during which scientists from Jupiter Four updated them on Ganymean matters.
The Ganymean ship had almost certainly been destined for a large-scale, long-range voyage and not for anything like a limited exploratory expedition. Several hundred Ganymeans had died with their ship. The quantity and variety of stores, materials, equipment, and livestock that they had taken with them indicated that wherever they had been bound, they had meant to stay.
Everything about the ship, especially its instrumentation and control systems, revealed a very advanced stage of scientific knowledge. Most of the electronics were still a mystery, and some of the special-purpose components were unlike anything the UNSA engineers had ever seen. Ganymean computers were built using a mass-integration technology in which millions of components were diffused, layer upon layer, into a single monolithic silicon block. The heat dissipated inside was removed by electronic cooling networks interwoven with the functional circuitry. In some examples, believed to form parts of the navigation system, component packing densities approached that of the human brain. A physicist held up a slab of what appeared to be silicon, about the size of a large dictionary; in terms of raw processing power, he claimed, it was capable of outperforming all the computers in the Navcomms Headquarters building put together.
The ship was streamlined and strongly constructed, indicating that it was designed to fly through atmospheres and to land on a planet without collapsing under its own weight. Ganymean engineering appeared to have reached a level where the functions of a Vega and a deep-space interorbital transporter were combined in one vessel.
The propulsion system was revolutionary. There were no large exhaust apertures and no obvious reaction points to suggest that the ship had been kicked forward by any kind of thermodynamic or photonic external thrust. The main fuel-storages system fed a succession of convertors and generators designed to deliver enormous amounts of electrical and magnetic energy. This supplied a series of two-foot-square superconducting busbars and a maze of interleaved windings, fabricated from solid copper bars, that surrounded what appeared to be the main-drive engines. Nobody was sure precisely how this arrangement resulted in motion of the ship, although some of the theories were startling.
Could this have been a true starship? Had the Ganymeans left en masse in an interstellar exodus? Had this particular ship foundered on its way out of the Solar System, shortly after leaving Minerva? These questions and a thousand more remained to be answered. One thing was certain, though: If the discovery of Charlie had given two years’ work to a significant proportion of Navcomms, there was enough information here to keep half the scientific world occupied for decades, if not centuries.
The party spent some hours in the recently erected laboratory dome, inspecting items brought up from below the ice, including several Ganymean skeletons and a score of terrestrial animals. To Danchekker’s disappointment, his particular favorite-the man-ape anthropoid he had shown to Hunt and Caldwell many months before on a viewscreen in Houston-was not among them. "Cyril" had been transferred to the laboratories of the Jupiter Four command ship for detailed examination. The name, graciously bestowed by the UNSA biologists, was in honor of the mission’s chief scientist.
After lunch in the base canteen, they walked into the dome that covered one of the shaftheads. Fifteen minutes later they were standing deep below the surface of the ice field, gazing in awe at the ship itself.
It lay, fully uncovered, in the vast white floodlighted cavern, its underside still supported in its mold of ice. The hull cut a clean swath through the forest of massive steel jacks and ice pillars that carried the weight of the roof. Beneath the framework of ramps and scaffolding that clung to its side, whole sections of the hull had been removed to reveal the compartments inside. The floor all around was littered with pieces of machinery lifted out by overhead cranes. The scene reminded Hunt of the time he and Borlan had visited Boeing’s huge plant near Seattle where they assembled the 1017 skyliners-but everything here was on a far vaster scale. They toured the network of catwalks and ladders that had been laid throughout the ship, from the command deck with its fifteen-foot-wide display screen, through the control rooms, living quarters, and hospital, to the cargo holds and the tiers of cages that had contained the animals. The primary energy-convertor and generator section was as imposing and as complex as the inside of a thermonuclear power station. Beyond it, they passed through a bulkhead and found themselves dwarfed beneath the curves of the exposed portions of a pair of enormous toroids. The engineer leading them pointed up at the immense, sweeping surfaces of metal.
"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.
"Yes, if you like," the engineer affirmed. "I guess a bubble is as good an analogy as any. The interesting point is, if it did work that way, every particle of the ship and everything inside it would be subjected to exactly the same acceleration. Therefore there would be no G effect. You could stop the ship dead from, say, a million miles an hour to zero in a millisecond, and nobody inside would even know the difference."
"How about top speed?" someone else asked. ‘Would there have been a relativistic limit?"
"We don’t know. The theory boys up in Jupiter Four have been losing a lot of sleep over that. Conventional mechanics wouldn’t apply to any movement of the ship itself, since it wouldn’t be actually moving in the local space inside the bubble. The question of how the bubble propagates through normal space is a different ball game altogether. A whole new theory of fields has to be worked out. Maybe completely new laws of physics apply-as I said before, we just don’t know. But one thing seems clear: Those photon-drive starships they’re designing in California might turn out to be obsolete before they’re even built. If we can figure out enough about how this ship worked, the knowledge could put us forward a hundred years."
