Kassir radwan.elkassir@dargroup.com 1 Mechanical Department, DAH (S & P), Beirut, Lebanon The perception of events in two inertial reference frames in relative motion was analyzed from the perspective of the Special Relativity postulates, leading to the Lorentz transformation equations for the time and space coordinate in the relative motion direction. Yet, straightforward inconsistencies were identified upon examining the conversion of the time interval between two co-local events in the traveling reference frame. The approach used in the Special Relativity formulation to get around the identified inconsistencies was revealed. Subsequent mathematical contradictions in the Lorentz transformation equations, disproving the Special Relativity predictions, were shown. http://pubs.sciepub.com/ijp/2/6/3/ijp-2-6-3.pdf special relativity time dilation length contraction Lorentz transformation mathematical contradictions co-local and simultaneous events
