i was sitting here wondering what would happen if an orbital ring world around earth for instance, were to somehow shift it's orbit toward earth due to an accidental explosion or some other mishap. so maybe part of it ends up in the atmosphere, what would happen? how much force would it take for that to happen? is it not possible due to some gyroscopic force? what kind of accidents would be survivable and what would not. what about for the other kinds of massive structures, what kinds of disasters could they survive?
maybe do an episode on disasters, that'd be cool.
man-made and otherwise. i guess it'd be mostly man-made though because at that point we'd detect incoming natural disasters -shrug-
