So, I'm debating on buying the new computer game Elite - Dangerous. Stay with me, I'm not on the wrong forum. I was looking at all the 'cool looking' spaceships in the game and this thought occured to me. Since it's in space, why do spaceships have to be shaped aerodynamically? Here on earth where you have air molecules engineers spend a lot of time designing the shapes of surfaces to interact with those air molecules to optimise lift and minimize drag. But, if you are out in space that wouldn't really matter would it? I mean a spaceship that looks like a 'really cool airplane from the future' shouldn't fly any better than a spaceship that looks like a big cube or rectangle, correct? Or am I missing something?
