I don't. I wasn't thinking that light years is also a distance because I looking at an example for the problem that combined the two equations (length contraction & time dilation) which threw me off. It's basically t=d/v after you figure out velocity right?
Homework Statement
Suppose you decide to travel to a star 65 light-years away at a speed that tells you the distance is only 25 light-years. How many years would it take you to make the trip?
Homework Equations
∆t=∆t0/(√ (1−v2/c2 )) / ∆t0 = ∆t √(1−v2/c2)
L=L0√ (1−v2/c2)
