I think I'm wrong. You don't know where you're going cause the light hasn't left. but technically speaking FTL is impossible for various reasons. it breaks time travel and causality. But also any collision at speeds close to the speed of light would create nuclear fission or fusion. Check out this video as well from spacetime
