I am having trouble wrapping my head around the concept of the constant speed of light. Imagine I am moving in a ship at a certain speed (let's say 1/4 the speed of light). I send two probes out at the same speed, one directly ahead of me, one directly behind me. They are set to activate a timer when they separate from me, move an identical distance relative to me, and await a beam of light from me. I send a beam of light in each direction which stops each probe's timer. The probes then return to my ship and I compare timers. Will the timers have stopped at the same values, or will one probe's time value be higher than the other's? Thanks for any feedback.
