Robert Dicke's Momentous Error - A Comment on Rev.Mod.Phys. 29 (1957), p.363

Authors: Alexander Unzicker

It is shown that the paper `Gravitation without a principle of equivalence' by American Astrophysicist Robert Dicke (1916-1997) contains a simple, but consequential, technical mistake. The purpose of this comment however is not to blame Dicke, but to bring to mind the intriguing idea exposed in his article. The cosmology proposed by Dicke would have been in full agreement with Dirac's Large Number Hypothesis, had Dicke not gone astray at that decisive step. Instead of igniting the dispute with Dirac that followed (R. Dicke, Nature 192 (1961), p. 440; P. A. M. Dirac, Nature 192 (1961) p.441), the two researchers could have joined forces in creating an alternative cosmology that incorporated Mach's principle.
