These concentric [[event horizon]]s become [[Degenerate energy level|degenerate]] for 2''r<sub>Q</sub>'' = ''r''<sub>S</sub>, which corresponds to an [[extremal black hole]]. Black holes with 2''r<sub>Q</sub>'' > ''r''<sub>S</sub> are believed not to exist in nature because they would contain a [[naked singularity]]; their appearance would contradict [[Roger Penrose]]'s [[cosmic censorship hypothesis]] which is generally believed to be true.{{citation needed|date=January 2013}} Theories with [[supersymmetry]] usually guarantee that such "superextremal" black holes cannot exist.
The [[electromagnetic potential]] is
:<math>A_{\alpha} = \left(Q/r, 0, 0, 0\right).</math>
If magnetic monopoles are included in the theory, then a generalization to include magnetic charge ''P'' is obtained by replacing ''Q''<sup>2</sup> by ''Q''<sup>2</sup> + ''P''<sup>2</sup> in the metric and including the term ''P''cos θ ''d''φ in the electromagnetic potential.{{clarify|date=January 2013}}
