==Abstract==

Special relativity theory is not able to provide a satisfactory physical explanation for the behavior of matter and light. For example, when we move away at speed, from a source emitting light at speed, the photons appear to reach us at speed c and not c - v. This apparent constant speed of light with respect to a moving frame is perhaps the most fascinating phenomenon in science. The conventional explanation in terms of special relativity theory implies an esoteric space-time distortion, which is not compatible with logic. How can we explain the phenomenon more logically? We show here that all such phenomena can be explained using Newton's physics and mass-energy conservation, without space contraction or time dilation. We have seen previously that the principle of mass-energy conservation requires that clocks run at a slower rate in a moving frame, and that physical bodies become longer because of an increase of the Bohr atomic radius. The present paper gives a physical explanation for the apparent constancy of light speed. Constant light speed is an illusion: light speed is really c - v with respect to the observer, even if his tools always measure. The key to the explanation is the question: With respect to what does light travel? A physical understanding is crucial in clock synchronization and in running the Global Positioning System (GPS).
