Comparison of the Falling Light Experiment and the Ultracentrifuge Gamma Radiation Study

The discovery of the Mőssbauer effect had a great impact on experimental attempts to study basic open questions in the field of relativity.  Pound et al. carried out an experiment to measure the variation of the speed of light with gravitational potential by mounting a gamma ray Mőssbauer emitter on the roof of a building and detecting the radiation at ground level.  Hay et al. and others measured the dependence of the frequency of gamma radiation as a function of the speed of an absorber mounted on the rim of an ultracentrifuge/  In both cases the theoretical interpretation was based squarely on Einstein’s Equivalence Principle (EP), which assumes that kinetic and gravitational acceleration are basically indistinguishable.  In the present study these experimental results are analyzed on the basis of the Uniform Scaling method. It assumes that the units of physical properties vary with both the state of motion and position of the object and observer in a predictable manner.  It is pointed out that the properties of light do not change as the radiation descends in a gravitational field, thereby indicating that the local acceleration due to gravity on the photons is equal to zero.  This conclusion is supported by the assumption made by Schiff which successfully predicts the angle of displacement of star images observed during solar eclipses.  The conclusion for the variation of the frequency of the gamma rays is that it decreases with the rotational speed of the centrifuge, thereby indicating that a blue shift is observed at the rim of the rotor for radiation emitted near the axis.  It is pointed out that this result stands in contradiction to Einstein’s Symmetry Principle, which claims that two clocks in motion will both be running slower than one another at the same time.
