One of the cool things about space is that you can always rationalize it with
some kind of nifty technology, like navigational shields. :D
I don't think those micro-particles would care if your ship is aerodynamic,
since there's no air in space to carry the particles around the aerodynamic
shape. (does that make sense?)
