In a recent question that I asked, I received a response which presented time dilation as the result of a lack of simultaneity:
“It is better to think of time-dilation as being the result of a lack of simultaneity than vice versa. Imagine walking down a long corridor where every 10 metres there is a clock on the wall. If those clocks were set so that each was 1 second ahead of the previous one, then as you walked down you would see that the time on your watch was falling a second behind the clock every ten metres. You would not know if your watch was running slow or the clocks were out of synch- the two effects are inter-related” – Marco Ocram
This is a way of thinking about time dilation that I have never seen before. Previously, I have only thought of it in terms of the thought experiment of a light clock with a longer light path in the moving frame relative to the rest frame. Is this light clock perspective derived from the perspective of time dilation as the result of a lack of simultaneity? Are the two reconcilable ideas or completely different concepts? Thanks in advance.
