Hello all, Thank you for taking time to read my question. I am curious, what happens if following criteria is met; 1. Place a indestructable stopwatch inside the black hole set it to 5 second 2. Place another stop watch outside of black hole and set it to 5 second 3. Place a indestructable metal bar (does not flex, bend) that goes across both in and outside of black hole with a button pusher to activate both stop watch simultaneously. Question, 1. Will the timer end at the same time? If not, why? 2. If light speed is not involved in the equation, does the time continues normally? From what I understood, time slows down to compensate for light, because light speed cannot change, so if the light were to travel the same distance when affected by gravity, time has to slow down to compensate. But what if we just take light speed out of question and place a mechanical switch that pushs both timer's button at the same time from point A to point B. Will the timer still be affected by the time dilation? Thanks for taking time to read my noob question.
