Hypotheses
The hypotheses (rules) that are applied to the behavior of light follow from the previous considerations and an analysis of the examples discussed later. All of the hypotheses except possibly #2 have previously been declared incorrect and discarded when considered alone. Since they are interactive, they must all be considered as part of a single package in order to evaluate their relationship to the physical behavior of light. The hypotheses are listed below.
Hypotheses #1 and #2 are suggested by Maxwell’s equations of electromagnetism. Hypothesis #3 is suggested by and is consistent with the general behavior of light in a moving system. Hypothesis #4 is relevant to the calculations about the behavior of light rather than the behavior of light itself ; it applies to space and not specific objects, which may possibly vary their size as a function of their time/gravity environment.
If the behavior of light is analyzed with strict adherence to the above assumptions, its theoretical behavior should be consistent with its observed behavior in all circumstances.
