We know the case of the twin paradox and the explanation provided for it.
What about the following simplified example : A train moves relatively to a station (and vice versa):
-Station, with station guy in it and his clock, located at point B
-Train, with train guy in it and his clock, sitting at the exit door of the train.
>The train starts to move at point A at the beginning of the station and stops at point B at the end of the station.
(Let's just say there's no accellaration going on, it happened at a constant speed.)
>Say station guy observes a time dilatation of 1 minute as a result of this :
The station clock says 11.00h, and the train clock says 10.59h according to station guy, at point B.
At the same time train guy does the same experiment : He watches the station come closer :
The train clock says 11.00h and the station clock says 10.59h, according to train guy, at point B.
Nice,now the experiment is over, both guys sit down at the bar in the station, precisely located where the train stopped : point B.
The train is standing still in the station, and both guys can observe both clocks in the same instant.
>> What times do the clocks show ?
My personal view :
During both experiments :
Only the train moved relatively to : the station and the spacetime surrounding the earth.
The station did not move relatively to the spacetime surrounding the earth.
Therefore only the train clock has been influenced, and both guys will read the train clock at 10.59h and the station clock at 11.00h (or 10 minutes later at the bar they will read 11.09h and 11.10h)
Additional remarks:
Precisely the fact that both clocks indicate a different time, show that both experiments are not interchangeable.
I know of experiments proving the first experiment (or experiment of similar context), such as Hafele-Keating,
but i don't know of any experiments proving the second experiment, the one done by the train guy that is.
What are your comments ?
