The astrophysics of rotational energy extraction from a black hole
arXiv:2111.07796 · doi:10.1038/s41550-021-01527-5
Abstract
Recent work has called into question whether nature can extract the rotational energy of a black hole via electromagnetic fields by appealing to an alleged ability to absorb current. We describe the strategies needed to properly treat the astrophysics in curved spacetime near black holes, showing that while the Blandford-Znajek effect is sound, the deeper nature of the electric nature of black holes remains unresolved.
