For the following thought experiment, How to do calculation in relativity of simultaneity
Why is simultaneity considered as an act of seeing the bolts? Even for the passenger in the train, can we not argure that the event may actually be simultaneous for him as well, just that he perceived (with eyes) at a later point of time?
Instead of person in the middle of train doing the observation, I have an observer at each end of the train who just note the time of nearest bolt and tally them later. How do you think this changes things for the given experiment?
How is this thought experiment justified for explaining relativity of simultaneity as it's based on human senses ? Even with Galilean transformation wouldn't this experiment be still valid? Can we reformulate this thought experiment to not have human perception for measurement and still validate the relativity of simultaneity?
