I have a basic grasp of special relativity and understand why different observers will have different perspectives on the timing of events. My question is this, if Observer 1 sees two events occuring which change in time i.e of 2 lights opposite each other with the same color which change simultaneously, so red-red blue-blue green- green, and an observer moving at speed relative to Observer 1 may see red-blue blue-green green-red due to the change in angle of his time slice Both obervers are justified in saying that their observations are correct ( equivalence principle ?) Does this mean that for a moving observer 2 the observations of observer 1 are his past, and for observer 1 they are his present and the observations of observer 2 are observer 1's future So in effect Observer 1's future as "already occured" as observer 2 is experencing it. Am i living in someone elses past and someone elses future ? If so when does the future stop being mapped out ? Is/Was the whole of all time ( past future and present) concieved at once ? Clearly i am blaberring now and there is a good reason why the future is not already mapped out !! Please enlighten me !!
