Forbes: Brian Koberlein, "The Tale Of A 1986 Experiment That Proved Einstein Wrong" (6 Apr 2018)

• Secondary: popular-science commentary by an astrophysicist contributor. It is that author's characterization, and it relies on Marett (2012).

Points [web]

• The Nature 322 item is "a one column letter to the editor ... claiming he did an experiment with details to follow". Koberlein: "no peer review". Note: Nature correspondence is not refereed like articles, so this describes the format [memory, medium].
• He notes that geocentrist ("fixed Earth") websites cite the Nature letter heavily. That describes how the letter is used today, not the inventor's own aims.
• Gives the CMB dipole velocity as 371 km/s, against Silvertooth's 378.
• "the experiment was done several times and seemed to be consistent". Biography: Paramount engineer, Oscar for technical merit 1942, Air Force think tank.
• Summarises Marett: "Silvertooth's results were real, but his conclusions were wrong". The apparent wavelength shift tracked room temperature through laser alignment.
• References Winnie (1970), "Special relativity without one-way velocity assumptions", Philosophy of Science 37(2) 223-238. This is the conventionality-of-simultaneity literature, related to the inventor's claim 1.

Bearing

Claims 1 and 4. A mainstream-leaning popular account that accepts the observation and rejects the interpretation. Useful as the "mainstream view" input for the Physicist.
