This question already has an answer here:
A couple of years ago I've heard about an interesting (based on the hearing) story.
I didn't know what it is: a small tale or a novel.
The storyline is evolved around a first interstellar Spacecraft and life there - it allows for many peoples to live there. In this story (based on the hearing of mine) the evolution of life of people is described. And the most memorable thing was, in my interpretation:
Children start to asking, why in the old movies and books the sky often described as blue, red with no stars. But they knew that the sky is always black, they knew it by looking out of a porthole.
That's all I remember about the story.
