Hunt found that it took time to adjust to the idea of living as part of a tiny man-made world, with the cosmos stretching away to infinity on every side and the distance between them and everything that was familiar increasing at more than ten miles every second. 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.
He spent hours in the viewing domes along the outer hull, slowly coming to terms with the new dimension being added to his existence, gazing out at the only thing left that was familiar: the Sun. He found reassurance in the eternal presence of the Sun, with its limitless flood of life-giving warmth and light. Hunt thought of the first sailors, who had never ventured out of sight of land; they too had needed something familiar to cling to. But before long, men would turn their prow toward the open gulf and plunge into the voids between the galaxies. There would be no Sun to reassure them then, and there would be no stars at all; the galaxies themselves would be just faint spots, scattered all the way to infinity.
What strange new continents were waiting on the other side of those gulfs?
Danchekker was spending one of his relaxation periods in a zero-gravity section of the ship, watching a game of 3-D football being played between two teams of off-duty crew members. The game was based on American-style football and took place inside an enormous sphere of transparent, rubbery plastic. Players hurtled up, down, and in all directions, rebounding off the wall and off each other in a glorious roughhouse directed-vaguely-at getting the ball through two circular goals on opposite sides of the sphere. In reality, the whole thing was just an excuse to let off steam and flex muscles beginning to go soft during the long, monotonous voyage.
A steward tapped the scientist on the shoulder and informed him that a call was waiting in the videobooth outside the recreation deck. Danchekker nodded, unclipped the safety loop of his belt from the anchor pin attached to the seat, clipped it around the handrail, and with a single effortless pull, sent himself floating gracefully toward the door. Hunt’s face greeted him, speaking from a quarter of a mile away.
"Dr. Hunt," he acknowledged. "Good morning-or whatever it happens to be at the present time in this infernal contraption."
"Hello, Professor," Hunt replied. "I’ve been having some thoughts about the Ganymeans. There are one or two points I could use your opinion on; could we meet somewhere for a bite to eat, say inside the next half hour or so?"
"Very well. Where did you have in mind?"
"Well, I’m on my way to the restaurant in B section right now. I’ll be there for a while."
"I’ll join you there in a few minutes." Danchekker cut off the screen, emerged from the booth, and hauled himself back into the corridor and along it to an entrance to one of the transverse shafts leading "down" toward the axis of the ship. Using the handrails, he sailed some distance toward the center before checking himself opposite an exit from the shaft. He emerged through a transfer lock into one of the rotating sections, with simulated G, at a point near the axis where the speed differential was low. He launched himself back along another rail and felt himself accelerate gently, to land thirty feet away, on his feet, on a part of the structure that had suddenly become the floor. Walking normally, he followed some signs to the nearest tube access point, pressed the call button, and waited about twenty seconds for a capsule to arrive. Once inside, he keyed in his destination and within seconds was being whisked smoothly through the tube toward B section of the ship.
The permanently open self-service restaurant was about half full. The usual clatter of cutlery and dishes poured from the kitchens behind the counter at one end, where a trio of UNSA cooks were dishing out generous helpings of assorted culinary offerings ranging from UNSA eggs and UNSA beans to UNSA chicken legs and UNSA steaks. Automatic food dispensers with do-it-yourself microwave cookers had been tried on Jupiter Four but hadn’t proved popular with the crew. So the designers of Jupiter Five had gone back to the good old-fashioned methods.
Carrying their trays, Hunt and Danchekker threaded their way between diners, card players, and vociferous debating groups and found an empty table against the far wall. They sat down and began transferring their plates to the table.
"So, you’ve been entertaining some thoughts concerning our Ganymean friends," Danchekker commented as he began to butter a roll.
"Them and the Lunarians," Hunt replied. "In particular, 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. All these attempts people are making to show it might be different don’t convince me much at all."
"I’m very gratified to hear you say so," Danchekker declared. "The problem, however, is proving it."
"Well, that’s what I’ve been thinking about. Maybe we shouldn’t have to."
Danchekker looked up and peered inquisitively over his spectacles. He looked intrigued. "Really? How, might I ask?"
"We’ve got a big problem trying to figure out anything about what happened on Minerva because we’re fairly sure it doesn’t exist any more except as a million chunks of geology strewn around the Solar System. But the Lunarians didn’t have that problem. They had it in one piece, right under their feet. Also, they had progressed to an advanced state of scientific knowledge. Now, what must their work have turned up-at least to some extent?"
A light of comprehension dawned in Danchekker’s eyes.
"Ah!" he exclaimed at once. "I see. If the Ganymean civiization had flourished on Minerva first, then Lunarian scientists would surely have deduced as much." He paused, frowned, then added: "But that does not get you very far, Dr. Hunt. You are no more able to interrogate Lunarian scientific archives than you are to reassemble the planet."
"No, you’re right," Hunt agreed. "We don’t have any detailed Lunarian scientific records-but we do have the microdot library. The texts it contains are pretty general in nature, but I couldn’t help thinking that if the Lunarians discovered an advanced race had been there before them, it would be big and exciting news, something everybody would know about; you’ve only got to look at the fuss that Charlie has caused on Earth. Perhaps there were references through all of their writings that pointed to such a knowledge-if we knew how to read them." He paused to swallow a mouthful of sausage. "So, one of the things I’ve been doing over the last few weeks is going through everything we’ve got with a fine-tooth comb to see if anything could point to something like that. I didn’t expect to find firm proof of anything much-just enough for us to be able to say with a bit more confidence that we think we know what planet we’re talking about."
"And did you find very much?" Danchekker seemed interested.
"Several things," Hunt replied. "For a start, there are stock phrases scattered all through their language that refer to the Giants. Phrases like ‘As old as the Giants’ or ‘Back to the year of the Giants’… like we’d say maybe, ‘Back to the year one.’ In another place there’s a passage that begins ‘A long time ago, even before the time of the Giants’… There are lots of things like that. When you look at them from this angle, they all suddenly tie together." Hunt paused for a second to allow the professor time to reflect on these points, then resumed: "Also, there are references to the Giants in another context, one that suggests superpowers or great knowledge-for example, ‘Gifted with the wisdom of the Giants.’ You see what I mean-these phrases indicate the Lunarians felt a race of giant beings-and probably one that was advanced technologically-had existed in the distant past."
