So Alpha Centauri is about 4.37 lightyears from earth, but that's in Earth's frame of reference, if you could build a spaceship to go, say 9/10c relative to Earth how long would it take to get to alpha centauri, because then space-time would be warped and therefore it would no longer be 4.37 lightyears away relative to the space craft. Also what equation did you use so I can modify it if it takes to long(i'm writing a story, and it needs to be reasonable like 50 years or so if possible)
