Steve <steve7600@gmail.com> Wrote in message: > Youre suggestion that "Kinematic time dilation and space-time oscillations of G. waves are not related."Thats more or less the same as saying "inertial mass and gravitational mass are not related". It is not a fair analogy, as in classical mechanics these masses are equivalent, what is far from to be true for phenomena of time dilation and g. waves. In SR context, inertial mass is abandoned, as it is ambiguous direction dependent quantity. Some differences: Time dilation occurs even in flat spacetime. Time dilation is not periodic. Time dilation affects the mean measured time intervals. BTW, what is the supposed relation of G. waves and metre definition ? Much more relevant is to consider mechanical vibrations affecting metre reproducibility. ----- > Your comment"Every good textbook has arguments for that. The key is to realize a motion is not absolute. "Ok, so this regards whether or not there are preferred reference frames. If there was a preferred frame, then there would be observed assymetry of properties and behaviour of objects, depending on their absolute speed. As this is not observed, there is good reason to suppose there is no such a frame. > And without a preferred reference frame nobody can decide who is and who isnt moving. SR rejects a preferred reference frame and suffers the paradox that "your clock is running slower than my clock, while my clock is running slower than your clock". > No, this is SR misunderstanding. SR does not suffer paradoxes. It is the human mind that suffers, as it cannot wrap around unintuitive ideas of SR, so distant to everyday human experience. -------- > For all practical purposes a gravitating body services all the attributes of being a preferred reference frame, You confuse a frame of choice and a preferred frame. While this may be equivalent grammatically, they are very different physically. ---------- > and so this is what I have come to adopt. This more or less mashes SR and GR into a single construct, There is no mashing, SR is GR in flat spacetime, for what the S and G gives a direct hint. -- Libor Striz aka Poutnik ( a pilgrim/wanderer/wayfarer) "Humour is the only effective weapon against stupidity."
