WebApr 15, 2024 · In the case of Schwarzschild black holes, the event horizon is a spherical surface surrounding a singularity at the center of the sphere; the latter is a point at which the density would be infinite and the laws of physics, according to the theory of general relativity, lose their meaning. WebJan 19, 2024 · Spherical time-like orbits around a Kerr black hole were first studied by Wilkins [ 14 ], almost 50 years ago. In his groundbreaking work, he analysed many of their properties. In particular, he plotted out the parameter space of stable spherical orbits around an extremal Kerr black hole.

The no-hair theorem postulates that, once it achieves a stable condition after formation, a black hole has only three independent physical properties: mass, electric charge, and angular momentum; the black hole is otherwise featureless. If the conjecture is true, any two black holes that share the same values for these properties, or parameters, are indistinguishable from one another.
