Where is the electrostatic self-energy localized in general relativity?

Abstract

We discuss an alternative way of prescribing the spacetime geometry associated with a non-radiating distribution of charged matter. It is based on the possibility that the electrostatic self-energy does not reside on the Coulombian field but in a matter pressure term of electromagnetic origin localized at the sources. We work out completely the well controlled spherically symmetric case, questioning the realization of Reissner-Nordstrom geometry in nature. Finally, we sketch an experiment that could distinguish between the standard and the alternative scenario.
