Contemplating warp speed or FTL speeds, and after reading another thread that stated aerodynamics would become more important the faster a ship travelled through a not so complete vacuum, would collision with atomic particles be possible at those speeds? Stick with me, I'm in a philosophical mood (drunk). Being shot with a .22 caliber rifle at 1200ft/s would be the same as me running at a floating bullet at 1200ft/s, correct? This becomes a question for the sober mathematicians. If a 70 grain bullet traveling at 1.7 times the speed of sound can be lethal, at what velocity would a small molecule or speck of dust become a deadly projectile?
