Could rotating black holes be the wind turbines powering the distant future? We tested the physics

By Marion Cromb, Research Fellow in Physics, University of Southampton
Black holes are mysterious objects – there’s a lot we don’t know about them. One longstanding question has been whether rotating black holes, which are so powerful they drag space-time along with them, could be used as an energy source.

The physicist Roger Penrose suggested that, if an object fell into a rotating black hole in such a way that it split – with one part escaping – the part that left should effectively gain energy from the black hole.

So if we sent objects or light towards a…The Conversation
