“Moving Clocks Run Slow” plus “Moving Clocks Lose Synchronization” plus “Length Contraction” leads to consistency! The object of this exercise is to show explicitly how it is possible for two observers in inertial frames moving relative to each other at a relativistic speed to each see the other’s clocks as running slow and as being unsynchronized, and yet if they both look at the same clock at the same time from the same place (which may be far from the clock), they will agree on what time it shows! Suppose that in Jack’s frame we have two synchronized clocks C 1 and C 2 set 18 x 10 8 meters apart (that’s about a million miles, or 6 light-seconds). Jill’s spaceship, carrying a clock C' , is traveling at 0.6 c , that is 1.8 x 10 8 meters per second, parallel to the line C 1 C 2 , passing close by each clock. Suppose C' is synchronized with C 1 as they pass, so both read zero. As measured by Jack the spaceship will take just 10 seconds to reach
