Systematical scrutiny into special relativity

This paper examines some basic propositions of the special relativity theory. A Gedanken experiment is proposed to disprove Einstein's light speed invariance; the 4-dimension invariant seems invalid because it is impossible for the time and spatial coordinate variables to be orthogonal, because of their presumed cross-correlations; and the Lorentz transformation is therefore bounded to have an intrinsic arbitrariness. In addition, the well-known topic of the “relativity of simultaneity” turns out to be a false proposition, because of at least one logical error made by Einstein that violates the two postulates of his own theory. Einstein's theory is flooded with vital errors and flaws, and must be reexamined thoroughly as soon as possible.
