Ergosphere: Regions, Radial pull & Rotation

In astrophysics, the ergosphere is a region located just outside a rotating black hole, between its event horizon and a further external surface predicted by the Kerr metric which describes these objects. Its name was proposed by Remo Ruffini and John Archibald Wheeler during the Les Houches lectures in 1971 and is derived from Ancient Greek ἔργον…
