No, I am not making it up and it was not a dream A *charged black hole* is a black hole<http://en.wikipedia.org/wiki/Black_hole> that possesses electric charge <http://en.wikipedia.org/wiki/Electric_charge>. Since the electromagnetic repulsion in compressing an electrically charged mass is dramatically greater than the gravitational attraction (by about 40 orders of magnitude), it is not expected that black holes with a significant electric charge will be formed in nature.
A charged black hole is one of three possible types of black holes that could exist in the theory of gravitation called general relativity<http://en.wikipedia.org/wiki/General_relativity>. Black holes can be characterized by three (and only three<http://en.wikipedia.org/wiki/No_hair_theorem>) quantities, its - mass <http://en.wikipedia.org/wiki/Mass> *M* (called a Schwarzschild black hole <http://en.wikipedia.org/wiki/Schwarzschild_black_hole> if it has no angular momentum and no electric charge), - angular momentum <http://en.wikipedia.org/wiki/Angular_momentum> *J* (called a Kerr black hole <http://en.wikipedia.org/wiki/Kerr_black_hole> if it has no charge), and - electric charge <http://en.wikipedia.org/wiki/Electric_charge> *Q* (charged black hole or Reissner-Nordström black hole<http://en.wikipedia.org/wiki/Reissner-Nordstr%C3%B6m_black_hole> if the angular momentum is zero or a Kerr-Newman black hole<http://en.wikipedia.org/wiki/Kerr-Newman_black_hole> if it has both angular momentum and electric charge). A special, mathematically-oriented article describes the Reissner-Nordström metric <http://en.wikipedia.org/wiki/Reissner-Nordstr%C3%B6m_metric> for a charged, non-rotating black hole. The solutions of Einstein's field equation<http://en.wikipedia.org/wiki/Einstein%27s_field_equation> for the gravitational field <http://en.wikipedia.org/wiki/Gravitational_field> of an electrically charged point mass (with zero angular momentum) in empty space was obtained in 1918 by Hans Reissner<http://en.wikipedia.org/wiki/Hans_Reissner> andGunnar Nordström <http://en.wikipedia.org/wiki/Gunnar_Nordstr%C3%B6m>, not long after Karl Schwarzschild<http://en.wikipedia.org/wiki/Karl_Schwarzschild> found the Schwarzschild metric <http://en.wikipedia.org/wiki/Schwarzschild_metric> as a solution for a point mass without electric charge and angular momentum.
