WebJul 11, 2024 · The ergosphere is the area around a black hole that is influenced by the black hole’s gravitational pull. This area includes everything within the Schwarzschild radius, which is the radius at which the energy and momentum of a black hole are equal and the black hole’s gravity is able to pull everything in. Anything beyond the … The size of the ergosphere, the distance between the ergosurface and the event horizon, is not necessarily proportional to the radius of the event horizon, but rather to the black hole's gravity and its angular momentum. A point at the poles does not move, and thus has no angular momentum, while at the equator … See more The ergosphere is a region located outside a rotating black hole's outer event horizon. Its name was proposed by Remo Ruffini and John Archibald Wheeler during the Les Houches lectures in 1971 and is derived from the Greek … See more A suspended plumb, held stationary outside the ergosphere, will experience an infinite/diverging radial pull as it approaches the static limit. At some point it will start to fall, resulting in a gravitomagnetically induced spinward motion. An … See more As a black hole rotates, it twists spacetime in the direction of the rotation at a speed that decreases with distance from the event horizon. This process is known as the Lense–Thirring effect or frame-dragging. Because of this dragging effect, an object within the … See more • Chandrasekhar, Subrahmanyan (1999).
