sddfds Posted August 28, 2022 Share Posted August 28, 2022 hello i would like to ask if circular polarizers generate wormholes and warp drives. thanks very much. Link to comment Share on other sites More sharing options...

MigL Posted August 28, 2022 Share Posted August 28, 2022 IIRC, linear polarization confines the EM field along a plane in the direction of travel. Circular polarization has two such linear components, confinment to planes along the direction of travel, but perpendicular and 90o out of phase. I would hate to think my sunglasses can create wormholes ... Link to comment Share on other sites More sharing options...
swansont Posted August 29, 2022 Share Posted August 29, 2022 Black holes are one example of a singularity. Not all singularities are black holes. Optical singularities would likely have nothing to do with GR phenomena. The Laser Focus World link explains one kind of circular polarization optical singularity The waves interfere constructively in the bright outer zone, and destructively in the inner dark area, forming the central vortex where the amplitude is zero and the phase is thus undefined.
