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?)

Yeah, but also in aerodynamics and hydrodynamics, the sleeker it is, the less
resistance it encounters on it’s forward edge. If you minimize the amount of
forward contact on the front, less particles would hit it, causing less overall
damage. Think of it as Radar... a 747 which is big, and not very aerodynamic,
produces a huge Radar image, while the B-2, or the F-22 Raptor, which are rather
sleek and aerodynamic, produce a small radar image.
Although you still would need to deal with the ones that hit the ship.

So at 1/2 the speed of light, you would definately need some form of shielding. An old, and possible, idea is to use a barrier of (...) (21 years ago, 23-Jun-03, to lugnet.space, FTX)

Even though these ships are aerodynamic, they aren't SO aerodynamic that they deflect photons! and while photons are much smaller than your average particle out there, the particles that are present in a vacuum (...)

Well, in the space-ish situation, the number of particles you're hitting will only come down to size; regardless of its shape, a ship shaped like a perfect lozenge will hit the same number of particles as a ship shaped like a cube, if their (...)
