Black hole charge
Did you know?
A charged black hole is a black hole that possesses 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 … See more The two types of charged black holes are Reissner–Nordström black holes (without spin) and Kerr–Newman black holes (with spin).

WebFeb 3, 2024 · If the charge of the black hole is less than its mass (measured in geometric units G= c =1 G = c = 1 ), then the geometry contains two horizons, an outer horizon and an inner horizon. Between … WebWhen the black hole has a non-zero vector charge, the Gauss law insists on constant flux through a sphere of any radius, thus there are non-zero fields at large r and the Schwartzschild solution gets modified into a “charged black hole”. For asymptotically flat spaces there is the famous statement, much emphasized by Wheeler: there are ...
WebDec 26, 2024 · 1 Answer Sorted by: 2 A real black hole is unlikely to have any significant electric charge, because a distribution of matter that has enough charge to overcome the gravitational attraction would — for that very reason — not collapse to form a black hole. (Magnetic fields are a different story.
