Problems with "GR without SR: A gravitational-domain description of first-order Doppler effects" (gr-qc/9807084)

Abstract

Einstein's goal of producing an advanced gravitational model that was independent of special relativity's "non-gravitational" derivations has arguably still not been achieved. The author produced a paper in 1998 outlining a possible method of attack on the problem based on shift equivalence principles ("Doppler mass shift"). Some problems with this paper have since come to light. We list some further developments, some papers not cited in gr-qc/9807084, some experimental results missed by the author, and identify a problem with the paper's approach to aberration effects.
