I'm wondering how close can you get to C before wind drag becomes a problem. After all, if the ship is going .999999C, then any particles it hits are also going .999999C, and even if there aren't many of them per cubic meter that's going to add up. Another factor is that with number of particles hit per second ship time goes up proportionally with time dilation (although occupants of the ship would see that as length contraction).

(And that's ignoring the gamma rays and maybe other radiation generated each time one of those .999999C particles hits the ship.)


That is a definite problem. Go fast enough and you'll quickly be reduced to subatomic particles. Don't know how fast you need to go, though. I suppose it depends on what you hit.
