Recent work has questioned whether nature can extract the rotational energy of a black hole via electromagnetic fields. Although we show that the Blandford–Znajek effect is sound, the deeper physics of the electric nature of black holes remains unresolved.

从黑洞中提取旋转能量的天体物理学

最近的工作质疑大自然是否可以通过电磁场提取黑洞的旋转能量。尽管我们证明 Blandford-Znajek 效应是合理的，但黑洞电性质的更深层次物理学仍未解决。
