We trivialy understand the concept by reading a vague sci-fi scenario of it in the gp post. Wouldn't the travellers have movies, books and stuff and understand the concept of planet life too?
It would have to be relatable? So instead of talking about planets, it might call it a giant spaceship orbiting a single star for billions of years. One so big you can’t even walk in a single lifetime with water reservoirs so big you can’t see the other side of them. Even with pictures and movies, it would be like looking at pictures and movies of the 18:00s today. It’s cool to see, but the people in them are dressed weird, their problems so foreign to us, and their speech barely makes sense. Instead, they’ll be watching “Wives In Corridor 84” and all with slang we can’t even begin to predict. Add another thousand years to that, and there’ll have to be translators who can convey the original text/voices of the originals. They’ll even have to translate how to do survival, which nobody will have actual experience with, so they might even view it as religious acts that few people will believe. Like, why would you need to learn how to build a shelter when youve had one passed down through generations? When we stop at this spacecraft orbiting a star, and transfer to it, surely there would be shelter on a spacecraft?
Sure I think I agree with you but I believe that the travel itself is the main issue not like figuring out how to make a fishing rod and setup an anarchist commune when you arrive (assuming habitable planet).
I.e. some 'Lord of the Flies' bottleneck where there are no wise adults to convey culture etc on the ship.
