Web13 okt. 2024 · This is exactly what is happening in the Euclidean Kerr metric. If one defines the variable Φ ≡ ϕ − Ω t where t is euclidean time, then the equivalence relations are ( t, Φ) ∼ ( t + β, Φ) ( t, Φ) ∼ ( t, Φ + 2 π). If one uses ϕ = Φ + Ω t, then this becomes ( t, ϕ) ∼ ( t + β, ϕ + β Ω) ( t, ϕ) ∼ ( t, ϕ + 2 π).

Web5 mrt. 2024 · 7.1: Killing Vectors. The Schwarzschild metric is an example of a highly symmetric spacetime. It has continuous symmetries in space (under rotation) and in time (under translation in time). In addition, it has discrete symmetries under spatial reflection and … 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.
