Abstract

In this paper, the Selleri transformations along with the light speed predictions of “equivalent” space-time transformations, clock synchronization, and one-way light speed measurement are discussed. First, using a one-way light speed calculation, it is reaffirmed that the Selleri transformations are not equivalent to any in the set of “equivalent” transformations developed by Selleri (which includes the Lorentz transformations). They stand alone as the only transformations that accord with light speed observation and for which the condition of absolute simultaneity is satisfied. Second, it is shown that one-way light speed can and has been measured despite claims suggesting otherwise since synchronized clocks associated with the highly successful GPS are available for this measurement. Third, a new one-way light speed test is described that does not require clock synchronization of any kind. This is contrary to the popular belief that one-way light speed cannot be measured independently of a convention on clock synchronization.
