Tachycon

It is interesting that tachyons may emerge from under the event horizon. An observer located in the vicinity of a black hole could "see" tachyons appearing that move at the speed of light. This is easy to verify by considering the propagation of light signals in the Lemaitre metric. The trajectories of tachyons lie outside the light cone and therefore these particles may move away from the center even in a collapsing T region. Without making any assumptions concerning the magnetic or electric properties of tachyons we can conclude that strong gravitational fields are needed to increase substantially the energy of background tachyons. In this respect, ideal objects for pumping energy to tachyons are black holes in whose neighborhood interaction of tachyons with ordinary particles may produce observable effects. Note that the allowance for the interaction with tachyons in the vicinity of a true singularity may be especially important.
