Abstract: The Theory of Special Relativity has two requirements i relation to the behavior of light.  The first is that the speed of light is independent of the speed of its source.  The second is that the speed of light is measured as a constant by observers in Inertial Frames, who are travelling at uniform speed relative to each other.  the first requirement is confirmed as correct in this paper; the second is contradicted.  The fact that a light signal that is sent both clockwise and anti-clockwise, around a path on a rotating disk, takes different times to return to the source. was discovered by Sagnac over eighty years ago.  An explanation of this phenomenon is put forward, which leads to the conclusion that time recorded aboard a moving abject does not differ from time recorded by a stationary observer, and that the dimensions of moving and stationary objects are the same.  It is also shown fro tests that electromagnetism does not depend solely on relative motion.  A new theory is put forward which is in conformity with both the Michelson-Morley and Sagnac experiments, and with tests on electromagnetism.
