A signal can propagate in arbitrary speed, if one solves a system of equations that doesn't take all fields in considerations. Even Maxwell equations allows that, in the coulomb gauge, and electric field to propagate faster than light. But even so, relativity is not violated, since the equations are still Lorentz invariant, because the magnetic part is not directly manifest in the solution.
A similar situation happens in quantum mechanics, in free space, if you only look for oscillations, that is signals, rather than wave packets. A wave packet carries information, the measured value. In both cases you can claim to send information faster than light. This is a wrong claim, since you are not sending information, but just recording gibberish waiting for the information to appear. 2014-03-04 17:28 GMT-03:00 Axil Axil <janap...@gmail.com>: > In an experiment, Yevgeny Podkletnov claimed to have sent a signal over a > distance of 1 kilometer at a superluminal speed of 64C. > > This was done using superconductive projections of a rapidly rotating > magnetic field.
