true vaccuum, is it? There is all sorts of stuff out there, even if it is only
on a molecular or atomic level. So if a spaceship had a revolutionary drive
which would allow it to travel close to lightspeed (let's stay true to Einstein
and assume faster is no option) it should be very aerodynamic or its would
sustain heavy damage from even the smallest of particles out there. Am I right
or have I completely overlooked something?

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, I thought that when they would develop near lightspeed capabilities, they would develop shields, too! What if you just put water all over the hull? It would instantly turn to very hard ice and that would shield the ship against (...) (21 years ago, 23-Jun-03, to lugnet.space)

(...) 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. (...) (21 years ago, 23-Jun-03, to lugnet.space, FTX)

(...) Ah, now your not talking about dynamics as such, but surface area too. the aerodynamic comes into play with the angle of reflection. Trav (-|-) (21 years ago, 24-Jun-03, to lugnet.space)
