Web14 apr. 2024 · It’s a touchless sphere surrounding the black hole. And that’s as close as we can get to a black hole. The region from a singularity, the center of a black hole, up to the event horizon, called the Schwarzschild radius, makes up the black hole. Everything inside it is hidden from us, forever. WebLight can orbit a black hole. However, this is possible at exactly one radii, the innermost bound circular orbit (IBCO). The only possible orbit for light is therefore an unstable circular orbit. The possible orbital planes of light at the IBCO form a sphere around the black hole called the photon sphere. In this article, we’ll be going over ...

Since a Schwarzschild black hole has spherical symmetry, all possible axes for a circular photon orbit are equivalent, and all circular orbits have the same radius. This derivation involves using the Schwarzschild metric, given by For a photon traveling at a constant radius r (i.e. in the φ-coordinate direction), . Since it is a photon, (a "light-like interval"). We can always rotate the coordinate system such that is constant, WebThe outer surface of the ergosphere is the surface at which light that moves in the direction opposite to the rotation of the black hole remains at a fixed angular coordinate, according to an external observer. Since massive particles necessarily travel slower than light, massive particles will necessarily move along with the black hole's rotation.
