Magnetic ‘balding’ of black holes saves general relativity prediction
Black holes aren’t what they eat. Einstein’s general relativity predicts that no matter what a black hole consumes, its external properties depend only on its mass, rotation and electric charge. All other details about its diet disappear. Astrophysicists whimsically call this the no-hair conjecture. (Black holes, they say, “have no hair.”)
