Observed relativistic effects are due to a moving clock second contains a different amount of absolute time than the observer's clock second.

From: Michael Moroney on 20 Mar 2010 21:57 Hey, fool. A crazy musician composes his musical masterpiece where one of the "instruments" is a train horn. The audience, on a train platform, is supposed to hear the horn at the tone of "A" above Middle C (which is 440 Hz BTW). The train will approach the station at 60 mph. 1) What frequency horn should the composer request to be installed on the train, so that the audience will hear it at the correct frequency? 2) Has the composer, (or the train engineer, or anyone else,) by installing the correct horn, redefined "A" above Middle C? Why or why not?

Hey idiot....you are describing a doppler situation. It got nothing to do with the sychronization of two relatively moving clocks.

Hey idiot because the rate of the GPS clock compared to the ground clock is not doppler effect dependent. |
