1. The problem statement, all variables and given/known data You wish to travel to the Pleiades (at a distance of 130 pc) in 10 years, according to the clock that you carry. How fast do you have to travel to accomplish this (express the velocity as a fraction of speed of light, v/c)? 2. Relevant equations [tex] \Delta T = \gamma \Delta T_0 [/tex] 3. The attempt at a solution I've been stuck on this for hours, and I really don't know how I'm supposed to set this up. If someone could just help me set it up, I can do all the calculations myself.
