Some grand unified theories predict very heavy examples, especially in certain gauge theories containing Higgs bosons. In 1931, Dirac proposed that they would explain why electric charge comes only in multiples of the electron charge, but Maxwell's third equation holds that they do not exist. FTP, what are these hypothetical particles with an isolated elementary north or south magnetic charge?
