They are different, in the ground frame. And this is quite measurable, as the arrival times at planes equidistant from the golf ball at break-up are very different. Compare this with the contrary result with gammas from the pion. > > Tom, it is now obvious that Einstein's silly theory has to rely on fringe > experiments like this just to maintain its existence in an increasingly > skeptical scientific world. I love this: "fringe experiments". As in, "Any experiment that is specifically aimed to test a prediction of relativity and in fact shows support for relativity should be discredited as 'fringe' because... well, just because." > > >Tom Roberts > > Henry Wilson... > > .......A relativist's IQ = his snipping ability.

That depends, I suppose, on what you consider convincing. In your case, you are waiting for the theory to hold you down and force you to cry uncle, otherwise it's not convincing. Since that hasn't happened yet, you are unconvinced. But then, your average lawn ornament is unconvinced by the same metric. > His second postulate requires an aetherlike spatial reference frame, anyway. > > Henry Wilson... > > .......A relativist's IQ = his snipping ability.
