This is exorbitantly correct.

Well, this gymnastics is again courageously hypothetical. Merely a 
gedanken. You can't possibly project anything, travelling at that high 
speed, on a stationary axis. To do that you need some shadows of some art, 
also considered straight and not curved. (yes, if light can curves, its 
shadow may curves as well)
