Query: Method of images applied to an opto-mechanical Fabry-Perot resonator   The method of images, when applied to an opto-mechanical Fabry-Perot
resonator with a heavy, charged mirror, and a light, charged mirror that can be
driven into motion, reveals that the highest order images can move
relativistically when the Q of the superconducting resonator is on the order of
10^10. The implications of such relativistic motions of the charge and mass of
these images to the emission of electromagnetic and gravitational radiation
within the resonator is explored.
