Hi Terry, > IMHO, we will only succeed in tying ourselves into unsolvable knots similar to religious fanaticism if we insist there MUST exist an ABSOLUTE frame of reference. SR, would seem to suggest there ain't no such animal and never was - period. Ah, but that is the key. SR is not bas

Hi Harry, Thanks for posting the derivation. This is one of those cases where E=mc^2 appears to be true, because the math predicts a value that is useful. As I pointed out, however, E=mc^2 is not always true, such as in the case of nuclear binding and unbinding. Nuclear fission, regardless of w
