A potentially important consequence follows for future interstellar flight. Simply by traveling fast enough, an astronaut can reach any destination within a specified amount of (shipboard) time. The table below gives the travel times, as measured by onboard clocks, to Arcturus, located 36 light-years (11 parsecs) from the Sun, for a spacecraft traveling at various speeds (given as fractions of the speed of light, c).
Impressive though these results seem, they do not take into account the profound human problems which would surely follow from time dislocation.
