Logical analysis of concepts and conclusions reveals that key concepts of SRT, such as ‘simultaneity’ and ‘relativity principle’, are ambiguous, and that Einstein’s conclusions, derived from questionable thought experiments, are false. Empirical data, obtained from recent supernovae observations, point to the fact that the velocity of light is not constant across the radiation spectrum. But the most convincing argument against SRT comes from the fact that it is based on the Lorentz Transformation (LT) which is mathematically correct but physically invalid.
The Doppler effect, in all standard textbooks, is treated as though it applied only to waves - whether of light or of sound. But it applies equally well to pulses, and is much easier to comprehend and to characterize mathematically.
The Doppler effect for light is symmetric (it doesn't matter if the source is moving or the receiver), and depends only on the separation rate between the source and receiver. In the case of sound, where there is a carrying medium, the effect is asymmetric.
Supernovae, and in particular, type 1A supernovae, give us some insight into the age of the universe, as well as its rate of expansion. Type 1A refers to those supernovae which lack hydrogen in their spectra. This differentiates them from other stars and supernovae, and suggests that they originated near the very beginning of time. The data, reinterpreted using the results developed here, point to a much smaller and younger universe than currently believed.
The chapter on the Lorentz Transformation has been revised and shortened. It shows that on empirical grounds Einstein's most basic principle that the speed of light is independent of the motion of the source is false.
