→Theoretical Basis
Physically, either this produces "imaginary" energy, time passage, length contraction, etc., or the imaginary number is cancelled. An example of this in the above energy equation is if the tachyon has an "imaginary mass." Further attempts at tangible clarification are pure speculation.

Also note that, in contrast with sublight particles, tachyons give Lorentz factors such that
::<math>Im( \gamma) < 1</math>
and, in fact, the further past the speed of light a tachyon goes, the closer the Lorentz factor gets to zero:
::<math>\lim_{v \to \infty} \gamma = \lim_{v \to \infty} \frac{1}{\sqrt{1 - \frac{v^2}{c^2}}} = 0</math>
