Special Relativity, time dilation, Lorentz contraction, speed of light postulate, addition of velocities
In this paper, it is shown that the classical addition of velocities is unavoidable, and follows naturally from an intrinsic physics concept. It is revealed that the relativistic addition of velocities and the Lorentz contraction simply lead to time transformations contradicting the Special Relativity predictions. Ironically, the Special Relativity time dilation prediction could be obtained from the classical addition of velocities and the Lorentz contraction, when the travel time of a two-way light trip is considered. A one-way (forward or backward) travel time leads to contradictions with the Special Relativity predictions. The special relativity time dilation factor could be obtained from the classical addition of velocities for a light trip in the transverse direction, but in contradiction with the speed of light postulate. Analyzed light travel time between relatively moving frame origins offers outcomes inconsistent with the Special Relativity.
