From the platform, we see it one way, from the train, another. All the same, it is convenient to think of the station as stationary so that it offers a reference point. The difficult arises when someone who is neither the station or the train has to report back. And where does he or she stand? If 'the train is standing in the station waiting to refuel', both the train and the station are neverthless moving in relation to the sun, the moon, and the stars: they are turning around galatically. Now, if they are turning around galactically, it is possible that they are, in turn, turning upon something else, but if they are, that something else must in turn be turning upon another thing and so on. And we can never find the last thing, simply because if we did there would have to be another last thing that found that thing, and so, forth we would have to go, but it may turn out that we are only dealing with a logical problem! Physics relies on relational movements within the relational university. As to gravity in physics, it is a bit like 'g' as a postulate in IQ assessment! There is of course an assymetry as regard the station clock- but only as regards things that are at different speeds fromit. -- Harbinger.
