“…Although different tachyon detection techniques have been considered for more than four decades (see, e.g., [159]), these particles remain to be discovered; however, one case is known in which experimental indications of the existence of tachyons were observed [160,161]. In these works, A.A. Tyapkin (1926Tyapkin ( -2003 from relativistic lead ions generated by the accelerator at CERN.…”

Prior to the development of Special Relativity, no restrictions were imposed on the velocity of the motion of particles and material bodies, as well as on energy transfer and signal propagation. At the end of the 19th century and the beginning of the 20th century, it was shown that a charge that moves at a velocity faster than the speed of light in an optical medium, in particular, in vacuum, gives rise to impact radiation, which later was termed the Vavilov-Cherenkov radiation. Shortly after the development of Special Relativity, some researchers considered the possibility of superluminal motion. In 1923, the Soviet physicist L.Ya. Strum sug gested the existence of tachyons, which, however, have not been discovered yet. Superluminal motions can occur only for images, e.g., for so called "light spots," which were considered in 1972 by V.L. Ginzburg and B.M. Bolotovskii. These spots can move with a superluminal phase velocity but are incapable of transferring energy and information. Nevertheless, these light spots may induce quite real generation of microwave radi ation in closed waveguides and create the Vavilov-Cherenkov radiation in vacuum. In this work, we consider various paradoxes, illusions, and artifacts associated with superluminal motion.

“…The coordinate transformations expressed by (20) show that the origin of the frame S ′ moves with respect to the frame S with a uniform velocity v along the common Z-axis in the flat spacetime background [12]. The solution of the Einstein-Maxwell equations obtained by us has the following characteristics: (a) the gravitational field given by the line element (5) has all the geometrical characteristics of the Reissner-Nordström field, (b) the solution is axially symmetric which is required as there cannot be a tardyonic observer which can find a tachyon at rest, and (c) it contains a velocity parameter v, which is not possible to be transformed away for |v| > 1. However, for |v| < 1, the solution transforms to the Reisnner-Nordström solution.…”

An axially symmetric exact solution of the Einstein-Maxwell equations is obtained and is interpreted to give the gravitational and electromagnetic fields of a charged tachyon. Switching off the charge parameter yields the solution for the uncharged tachyon which was earlier obtained by Vaidya. The null surfaces for the charged tachyon are discussed.Comment: 8 pages, LaTex, To appear in Pramana- J. Physic
