Grossly Inefficiencies in Lifestyles, Glass bottles and cups, livestock
I can understand having some extra space and comforts for a life time journey. But seriously, livestock? How can they grow the extra grain to feed them and handle their waste? Or have all that booze, and in glass bottles too? Don't forget all the make-up and cosmetics for the women. And would they have the luxury of even ejecting a dead body into space? No doubt they would have to let a human corpse decompose and get recycled just like the carcasses of the livestock. They seem to treat the star ship as if it was a luxury liner that would be no more than 2 weeks from the next port.
I can accept the plot device of a class structure. But how class divergent can you get in a sealed community of 600? How can you have luxury positions like the stewardesses or hair stylists? People will have to know a bit about every important job on the ship, much like even a cook on a submarine has to be competent on all the basic ship's systems. Not to say you wouldn't have a class structure after a while, but you'd think a community that was planned and led by scientists wouldn't strive for some level of egalitarianism. and how can a woman get pregnant and give birth to an "unclaimed" child in a sealed ship?
What are they doing? Why do they come here?
Some kind of instinct, memory, what they used to do.
