Grand unification magnetic monopoles inside the Earth

Nature volume 288, pages 348–350 (1980)Cite this article

Abstract

Elementary particle grand unification theories admit the possibility of very massive magnetic monopoles, but standard cosmology gives too many poles. Massive monopoles are affected both by gravity and magnetism, requiring reassessment of existing monopole searches. Monopoles inside the Earth would be able to annihilate with each field reversal, thereby giving rise to additional internal heat. This perspective is used to estimate an upper limit for the monopole-to-baryon ratio at accretion of 10−28.
