True scientists must use the Natural Phenomena demonstrated by Nature to advance knowledge. Nevertheless, are the conclusions about the effects of these empirical experiments reached by these people correct and true? Or are these tainted by dogmas. D.Y.K.

If you mean by the models we construct of reality .. if they are found to be at odds with the experimental evidence, it is the models that are changed. Unless any tainting is consistent with the evidence, then it won't last.

Whats wrong, didn't see this? John Archibald Wheeler is repitable, isn't he? I guess me and that other author are in good company. http://www.google.com/search?sourceid=navclient&ie=UTF-8&rlz=1T4TSHB_.... Using above Google search I found Spacetime physics: introduction to special relativity - Google Books Result by Edwin F. Taylor, John Archibald Wheeler - 1992 - Science - 312 pages Use the Einstein relation between photon energy £ and classical wave frequency / namely £CTM = WOT E = hf/c2 and £' = hf/c2, to derive the transformations Conrad J Countess
