Apparent Source Theory and Stellar Aberration

Authors: Henok Tadesse

This author has already proposed a new theory, Apparent Source Theory ( AST ), that can explain the Michelson-Morley experiment, the Sagnac effect, the Silvertooth experiment, the Roland De Witte experiment, the Venus planet radar range data anomaly ( analyzed and reported by Bryan G Wallace ) and other experiments. According to AST, there will be an apparent change in position of a light source as seen by the observer, for absolutely co-moving source and observer. The 'null' result of the Michelson-Morley experiment (MMX) is explained as follows. The effect of absolute motion is just to create an apparent change in position of the light source relative to the detector. There will be no (significant) fringe shift in the MMX for the same reason that there will be no (significant) fringe shift if the source position was actually, physically shifted slightly. The fringe shift in Sagnac effect is explained as follows. The source will be apparently shifted away relative to the detector when looking in the backward direction and shifted towards the detector when looking in the forward direction, hence creating a path difference. Einstein's thought experiment ( 'chasing a beam of light' ) is re-interpreted and used as one of the foundational arguments in this paper. The new interpretation is that it is the phase velocity of light that is always constant irrespective of source, observer and mirror velocity. The group velocity behaves in a more conventional way: it is independent of source (absolute) velocity but depends on observer and mirror velocity. For an observer moving near the speed of light away from a light source, the phases will still move past the observer at the speed of light while the group will be at rest relative to the observer. A contradiction between Apparent Source Theory and the phenomenon of stellar aberration has been found. The contradiction if found to be due to a conflict between conventional stellar aberration theory and the unconventional nature of Apparent Source Theory and hence is only an apparent contradiction.
