| Abstract: | We raise the question of whether velocities of left and right circularly-polarized photons might be different (for reasons
other than the well-known Faraday effect). Such a difference could manifest itself either in the time profiles of pulsed or
bursting astronomical sources or in the rotation of the direction of polarization of linearly polarized radiation from them.
The existing observations of pulsars, gamma ray bursters, and quasar jets are used to set limits to the difference in speed,
between 10-17and 10-32 |
