Gas falling into a black hole spirals inward like water down a drain. In this flow, magnetic loops constantly form and pop — somewhat like solar flares, but far more powerful. Each loop is a tiny magnet living its own life. When many of them are present, they start to influence each other: their north and south poles attract and repel in turn.

In quantum field theory, there is a long-standing mystery: infrared divergences. Usually they are seen as an annoying technical nuisance that must be carefully 'papered over' in calculations. But what if this is not a bug, but a feature?
