They cannot weigh more than 200 nanograms, and there cannot be more than one per 1029 nucleons.
They cannot weigh more than 200 nanograms, and there cannot be more than one per 1029 nucleons. Dirac showed their [*] charge must be 68.5 times that of an electron, or a multiple thereof. None have been found, though t'Hooft's work in Grand Unified Theories say they should exist—which would require rewriting Maxwell's equations. For 10 points—name these hypothetical magnetic particles.
