A good story, though I am not entirely sure whether formally and stilisticly it entirely matches the criteria of a short story. Anyway, I liked it!
I noticed something of which I don't know if it's deliberately so: In the end Miriam leaves her restricted code and starts using words like "ship", "stars" and even "galaxy" (a completely new one).
The story reminded me of some other stories on top of the citations already mentioned (which I didn't know myself BTW).
First Isaac Asimov's "Rendezvous with Rama" came to my mind. But of course the perspective is completely different. In Asimov's story the protagonists try to find out as much as possible about a massive interstellar ship that enters the solar system. In your story it's quite the opposite, the research being inside-out.
Then there a two stories that I read in a SF-anthology around the same time as Asimov's. I remember neither titles nor authors. One was about a human population living in the remnants of our civilization in a distant future, but not knowing anything about the technology that still runs it. That's until one of them accidentally discovers the control-room of the building they're in and learns how to switch on and off the lights. All the others can understand this only as an act of God. And the second is located in a generation ship orbiting the Earth. Something went wrong, its inhabitants don't have the slightest idea who and where they are. They have become much smaller then normal men and their biological clock ticks four times as fast. They are monitored by a human spy who lives among them under-cover, until of course one of them finds out the truth about them.
And then I seem to remember a movie I saw perhaps 30 years ago about the changes and mis-developments in the society on board, which has turned into a similar hierarchic society than you are describing, I think with "alphas", "betas" and "gammas", IIRC.
Of course, the generation-ship-motive will always result in some basic concepts that will be similar.
However, I think you have added to that some ideas I really like. And your story clarifies some issues about generation ships, that could well be reflected in Draco_Caeles' OXP.
The question of time and speed for example. The ship in your story has been travelling for a good 900 years, and its destination is still 423 years away. It originated from earth and is aiming at Tianve. Now, even if Earth is not present on the Elite and Oolite galactic map, we know it is not too far from Lave. (See
the wonderful and very informative website of Selezen for some reflections on that as well as on the timelines.) The distance from Lave to Tianve is 89.6 LY, so we can assume a distance between Earth and Tianve of roughly 90 LY as well. If we divide this 90 LY by the travel time (let's say 1350 years), we get 0.06666666666 LM as the generation ship's speed. This also seems more likely to me than the 0.145 Draco_Caeles has given them in his OXP, given the propelling technology that is assumingly in use.
This has other consequences as well. Given the speed of generation ships and the time Oolite is set in, we wouldn't expect to meet generation ships out of Galaxy 1. They simply couldn't have got out of the first galaxy by the time of Oolite, if we agree to the hypothesis that the eight galaxies are
distant areas of the same galaxy that can't be reached without wormholes. By the time of Oolite generation ships should be confined to a circle with a radius of roughly 60 LY around Lave. (Well, perhaps we shouldn't be too scrupulous about that.)
I like the idea of the Oracle and the whole religious cult. In the end we find out that "Oracle" in reality is an acronym for the ship's computer. Now, why would anybody name a computer to match
that acronym? And I guess this was deliberately done so. The answer springs to mind: Perhaps the whole religious cult is no aberration, but was carefully designed in the first place, from the very beginning, before the ship set on its journey? And why that? Because
only a religious cult would be strong enough to survive and keep the ship and the society on-board running for 45 generations, 1350 years! I find this a stunning idea.
I have however some doubts, as far as other details of the exposition are concerned. Allow me to share them here.
We learn that the people on-board obey the rules and rituals of their religious cult. Only as an enlightened person Miriam starts to question them. It seems to me that this kind of obedience perhaps is overfulfilling and therefore perverting the intentions of the generation who boarded the ship. Why is that?
It seems that even so extremely important tasks as e.g. maintenance of the ship and its engine are
only fulfilled and understood as a religious ritual. No doubt that this understanding helps the people on board to fulfill their duties to the letter, and--as I pointed out before--the religious cult may have been carefully designed to work that way. But at the same time the people seem to
completely lack any understanding of what they are actually doing, like how the engine works, what it does and, after all, what this all is good for. Even the death of a maintenance worker is understood as a punishment from God for not performing the ritual accurately, it is not understood at all as what it is, the result of contamination with some kind of radiation. My question is: Is this complete lack of engineering and, more so, scientific knowledge and skills probable? Even the word "analysis" is unknown! We have to bear in mind that the generation ship began its journey at some point in the 23rd century (Oolite being set in the 32nd), not in the middle ages or in mythological times (even if from their point of view the beginning of the journey
was in a mythological time). In other words: The civilization they came from
had scientific and engineering knowledge. After all this civilization wasn't extinct and developed the witchdrive afterwards. And that's only where they started! So: Why doesn't there seem to be any scientific knowledge preserved on the generation ship? It seems unlikely to me that in 900 years(!) the human mind shouldn't have developed any curiosity, shouldn't have done any research on what the world looks like, shouldn't have come up with new technical inventions. If all these powers and capabilities of the human mind were completely overcome by the religious cult, then the cult's designers definitely were
too successfull.
After all: What's the purpose of the journey? It's to finally arrive at Tianve and start a settlement there. How are the colonialists going to be prepared for that? They are going to need imagination, ingenuity, inventions, technical skills and a scientifically open mind, if they want to successfully colonize a completely unknown world. At this point their religious cult, which is designed to maintain their ship and the society within forever, will not help them anymore. Perhaps this is the big contradiction of their journey? When they pass the finish line, they will have forgotten everything they are going to need there? Because they
had to forget it in order to reach the finish line in the first place? That's an epic theme!
But still I'm not sure if it would be even possible to confine the human mind so much that it couldn't break free in 900 years.
Anyway, these are my toughts on--and inspired by--your story. So in inspiring these kinds of thoughts it's, by any means, a good story! I hope that some of my ideas can perhaps help you to further develop the concept of the generation ship. Feel free!
