&lt;br /&gt;
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&amp;#039;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).[[Category:Scientific Paper]]&lt;br /&gt;
