TACHYONS AND PSEUDOTACHYONIC RELATIVITY

I propose a reinterpretation of “Lorentz tachyonic transformations” — for |v| > c — and subsequently the fundaments of a Pseudotachyonic Relativity. We’ll see that some usually “absurd results” become comprehensible. Besides some brief reflections on issues of time inversion and causality, the main ideas and conclusions presented here are: • a tachyonic reference frame may only be detected as its “associated frame”, which has lower-than-light velocity (ˆv = c 2 /v) and in which time appears in an inverted flow; • we cannot directly detect tachyons but instead their pseudotachyonic “images”.
