Kerr metric equation
A rotating black hole is a solution of Einstein's field equation. There are two known exact solutions, the Kerr metric and the Kerr–Newman metric, which are believed to be representative of all rotating black hole solutions, in the exterior region. In the vicinity of a black hole, space curves so much that light rays are deflected, and very nearby light can be deflected so much that it travels several times around the black hole. Hence, when … Web14 apr. 2024 · Bethe-Salpeter equation for classical bound states via the \amplitude-action" relation [25, 53, 73{76]. Interestingly, the Hamilton-Jacobi action can be also used to describe massive probe particles moving in a Kerr metric beyond the equatorial case [77]. This raises the question of whether the boundary to bound dictionary
