Question

what is the accretion disk of black hole?

Answer 1

The most spectacular accretion disks found in nature are those of activegalactic nuclei and of quasars, which are believed to be massive black holes at the center of galaxies. As matter enters the accretion disc, it follows a trajectory called a tendex line, which describes an inward spiral.

Answer 2

black hole is a massive object whose gravitational field is so intense that no light electro magnetic radiaton can escape it .around many black holes iz an accretion disk of material emiting energy as it fall into black hole .this animation shows a cutaway of the accretion disk the gap between the accretion disk and the black hole represent the innermost orbit matter can be in before plunging into the black hole the radius of this innermost orbit depends on whether the black hole is rating are not if the black hole is rotating material can orbit in more closely , causing the material to move faster than if black hole is not rotating
