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…
