So, I'm creating this language and culture for these humans, where in the future, technology has allowed them to build orbital factories and they have successfully created one working prototype of an intergalactic star-ship.
Thousands of French (at about 30% of the total ship population), American/English (30%), Spanish (20%), and other Europeans from smaller countries board on a treaty agreed to by the members of a UN council.
Naturally, the language and culture are influenced heavily by the three main categories (and the people leaving for the other planet have studied the common language, which has a phonology and grammar structure based on French, English, Spanish, etc.).
They leave for a pre-agreed planet which would be similar to portions of the Earth, given that they use the Terraforming module installed on the ship. They would reach the planet after a period of 300+ years at maybe 50% c, as near-light-speed travel had not been invented yet (and simply because I hate the idea of things going faster than or at the speed of light; Einstein would have a headache).
Naturally, life-support systems include: a carbon dioxide to oxygen converter, a gigantic farming and ranching system, a water source (maybe from a water-recycling unit that re-uses all shower water, waste water, etc.?), an artificial gravity source (simple enough, just rotate), and etc. Their engine would primarily use matter-antimatter reactions to gain its initial velocity, and thrusters are arranged at three angles to the center engine for turning (however slow it would be) the ship.
My questions are:
Is this a realistic situation? Could somebody provide a reasonable answer for why they would agree to go on this mission (maybe as a method to demonstrate mutual peace after a devastating war, or maybe just to explore space)?
Is space travel realistic on this scale (as in, millions of people on one spacecraft)? Would a spaceship this size have structural integrity? Would local stars on the journey knock the ship off course enough to cause problems?
- If, during the travel (a few years before landing), they went through an asteroid belt unexpectedly (which is sketchy at best, maybe they couldn't turn fast enough?), could the structure be damaged enough in a focused impact so that one of the modules would break off?
And, if it did, assuming that this was one of the very specialized modules (maybe full of transportation devices for when they landed, or maybe full of vital electronics), would their technology timeline be sufficiently offset to set them back into a pseudo-Renaissance or Imperial time period, where the people are too busy colonizing the new worlds to advance technologically?
This is all very theoretical and highly improbable, but it is one of the axioms of my world. I want it to be isolated from Earth for centuries, but still have very poor technology so innovations would need to be redone. I'm sure I could rework it if it's implausible.
EDIT: I suppose the size of the spaceship and life-support systems would be a concern given this amount of people, so I'll rework the initial population to be about ~10,000 people. Is that a better estimate?
