The Kerr-Newman Horizon Condition for the Electron

Author: Egor Nikiforov

Abstract

The aim of this report is to investigate whether the electron can satisfy the horizon condition of a Kerr-Newman black hole. Since the electron has mass, spin, and electric charge, its physical parameters can be formally compared with the classical black-hole condition. After converting the electron's mass, charge, and spin into geometrized units, the calculation shows that the electron does not satisfy the black-hole condition because its spin and charge are very large compared with its gravitational mass. As a result, the electron cannot be described as a classical black hole. This illustrates why classical general relativity should be applied to quantum particles only with caution.
