Can Non Gravitational Black Holes Exists?
arXiv:gr-qc/9702054
Abstract
We claim that the existence of a mechanism such that photons may be trapped in a compact domain is not an exclusive property of gravitational forces. We show the case in which a non-linear electrodynamics allows such effect. In this latter case we should call this region an Electromagnetic Black Hole (EBH).
