Special Relativity, time dilation, length contraction, speed of light postulate
For relatively moving inertial frames, the constancy of the speed of light principle physically leads to time dilation in the transverse direction. This time dilation is irreconcilable in the longitudinal direction unless a length contraction in the relative motion direction is postulated. However, time dilation is contradictorily coupled with length expansion, a fact erroneously twisted in the special relativity and related text books, as demonstrated in this paper. The typical physical demonstration of the length contraction is shown to be inconsistent and contradicts its derivation from the Lorentz transformation. The misinterpretation of the Lorentz Transformation in predicting the length contraction is revealed. The constancy of the speed of light is consequently unviable.
