Superluminal communication, move and tachyon are incompatible with the special relativity. Introduction to the special relativity superluminal particles - tachyons (quantino) allows movement to the past, leads to disruption of causality denies Lorentz invariance and invariance of the speed of light - the second postulate of special relativity. Moving of superluminal particles into the past and violation of causality - this phenomenon, inherent only the special relativity. In reality no the movement to the past and there is no violation of causality. Predictions of special relativity in regarding to tachyon are wrong, absurd and rejects the invariance of the speed of light. Invariant`s should be the speed of tachyons. In this case, there is no movement in time and violation of causality. However, in the limits of its applicability, in part of their postulates the mathematic of the special relativity is irrefutable by any thought experiments.
Путенихин Петр Васильевич. Сверхсветовые связь, движение и тахион несовместимы со специальной теорией относительности. Введение в теорию относительности сверхсветовых частиц - тахионов (квантино) позволяет движение в прошлом, приводит к нарушению причинности, отрицает Лоренц-инвариантность и инвариантность скорости света - второй постулат специальной теории относительности.
