An example is considered (clock riddle) which demonstrates that opposite results are obtained for the length of an object depending on whether FitzGerald-Lorentz contraction (FLC) is assumed or instead the determination is based on the elapsed time required for a light pulse to traverse between its endpoints.…

Lorentz pointed out in 1899 that a relativistic space-time transformation that leaves Maxwell’s equations invariant could only be defined to within a common factor on the basis of then-existing experimental data. The present Note calls attention to the fact that Einstein’s subsequent derivation of the…

An experimental procedure is considered to measure the change in the length of an object when it is accelerated. The same theoretical assumptions that form the basis of the methodology for the Global Positioning System (GPS) are used in order to predict the results of the experiment. It is concluded…

Recent work has shown that the underlying assumptions of the Global Positioning System (GPS) are incompatible with a number of conclusions of conventional relativity theory, including Fitzgerald-Lorentz contraction (FLC) and the supposed ambiguity in the relative rates of clocks in motion. The challenge…

Recent evidence for neutrinos moving faster than light in free space is consistent with earlier measurements of the speed of light in condensed media in wavelength regions of anomalous dispersion. Both findings are widely assumed to be ruled out theoretically because they would violate Einstein causality,…

An experiment with cesium clocks carried onboard two aircraft as they circumnavigated the globe in opposite directions provided an important confirmation of the time-dilation effect of the special theory of relativity (STR). A key element in the discussion of this event was the fact that since a clock…
