smaller than the resolution with which the measurements were recorded. Though Maurice Allais and James DeMeo do not accept Shankland's refutation and hold to the belief that Miller's experiment invalidates the theory of relativity, Einstein's theory is today regarded by most physicists as proven, based largely on the vastly more accurate repetitions of Miller's measurements made using modern optical technology by numerous independent researchers that have shown conclusively that Miller's reported positive signal was spurious. Miller's data, and Shankland's analysis of it, are now of only historical interest. External links and references AIP International Catalog of Sources, summary of Robert S. Shankland audio archive.
