Of all the life-bearing planets in the galaxy, this overgrown wilderness of purple jungles was the last place they would have expected to find a space-faring race. But for the parabolic reflector melted into the planet's highest mountain and perfect crystal rising fifty meters to the focus, they would have said life here had not progresses to any technological level.
There was life, common enough on any planet with the right conditions, but not even the brief flicker of a technological civilization that flared as intelligent inhabitants discovered a planets untapped reserves. From experience, such short-term societies tended to collapse as soon as those resources ran out. But for some quirk in human history, perhaps they would have gone the same way but now they were out among the stars, finding the companionship of equals has become an obsession.
"Any luck with those marks, Su?" asked Will.
"Some," Su replied poring over the discolored lines in the walls. "These first few seem to be scalar values; base 16, fortunately."
Will smiled. "Why not?" he conceded. "The universe does love hex."
"These next ones have a familiar distribution. I think they're chemicals, it represents the periodic table, so this last more complicated one should be a chemical formula. I've got our Web node working on it now but it would be a lot faster if we had full Web connection."
Will sighed patiently. "We didn't solve the light-speed limit, we just found a few work-arounds," he said. "They work with physical objects, not data streams. Just another piece of technology that's failed to live up to its early promise."
"What's that supposed to mean?" snapped Su.
Six months in the confined quarters of their ship had left Will less conciliatory than usual. "Immortality," he snapped. "Weren't we supposed to have longer to work on these problems?"
"There's nothing wrong with the process," Su protested. "If there were, you and I would be long dead."
"And yet, we are the two oldest human beings by a wide and growing margin," insisted Will.
"The problems's not physiological. After five hundred years they just stop. Without hindsight, I would have expected those born to it to be better adjusted than us instead of the reverse being true. We expected nothing but thirty five years of meaningless struggle on a dying planet, we never had the luxury of asking why. You and I had a gradual introduction via longevity, and even that was unintentional. Our problems and theirs are completely different."
"They think they have so much time, it's impossible to get anything done," griped Will. "You know it took only fifty years to get the first probes designed and launched? Another hundred to solve the problem of sending living things beyond light speed? It seems the less there is to do, the longer they take. Immortality, even perceived, doesn't give them much incentive to actually finish anything. Working on the ship, they would spend decades arguing over the most trivial details. In the end, I just took it for a test flight."
"How did that go?"
"Pretty well so far, don't you think?"
Su laughed. "Will, did you ever have a vehicle you didn't steal?"
"How else do you think we would get a spacecraft for just the two of us?" asked Will. "Besides, they may not realize it but they need the results urgently. We had to leave Earth. The survivors descended from those mobile enough to dodge the worst of the climatic changes and find resources. Once that problem was solved we were suffocating on that tiny planet."
"And instead we find the loneliness and futility of space." Su pointed out.
"We've barely reached the stars and already we're in decline," mused Will. "Is it possible for an entire race to be lonely?"
"For want of a better word. We're not the first civilization, we've found their traces, so they must be out there."
"We are rare, Su," Will pointed out. "Perhaps not across the life of the universe but at any given time."
Su snapped out of the descending gloom as the results came back. She examined the screen closely. "It's a crystalline data store," she announced.
"But it's black, opaque," said Will, stating the obvious.
"All the better for absorbing solar energy to power its signal," Su flashed. "In which case, that last number must be the resonant frequency to access it." She adjusted the tool on a tripod and it began to hum. "Ah yes, up there in the x-rays. It looks like all we'll need to make sense of it is a translation matrix."
"How long is that going to take?" asked Will.
Su shrugged. "Probably not long, they wanted the data to be read."
"If we're not done by sunset, there's going to be another pulse," Will said. "Enhanced as we are, that microwave energy won't do us any good."
Su examined the results so far. "We have most of the concrete concepts and...oh,"
Will recognized the tone of disappointment in her voice. "You have a date?"
Su nodded glumly. "A quarter of a billion years,"
Will gazed in awe at the bowl. "But the mountain!" he protested.
"It's artificial, tough, probably the same material as the crystal."
They stared in silence. Finally, Will shrugged. "The closest so far," he said weakly. "Did it pinpoint their homeworld? Say where they went?"
"This was their homeworld. They came back here to die. They were trying to contact us and we weren't even there."
Will sighed. "I'm not ready to give up yet. We'll send a probe back to Earth, try and play up the positive side and give them something to strive for. That might buy us a few thousand years to find the real thing."
"And if we don't?"
"Then, perhaps, a few million years is all we get. Our species will join those who came before and be joined by those who come after."
They packed up their equipment and left as the mountaintop flared.
