KaluzaKlein Monopole
Abstract
By adding the trivial term dt^{2} one can convert the fourdimensional (positivedefinite) NewmanUntiTamburino line element into a static solution of the fivedimensional vacuum Einstein equations. Interpreted a\` la Kaluza and Klein, the solution describes a monopole with a chargetomass ratio of 2 in rationalized Planck units. Although it is a perfectly regular fivegeometry it appears singular from a fourdimensional perspective.
