There is a maximum spin rate that any black hole can have. If it spins faster than that maximum, its horizon disappears, leaving the singularity inside it wide open for all the universe to see; that is, making it naked — which is probably forbidden by the laws of physics

Why are black holes so different from all other objects in the macroscopic Universe? Why are they, and they alone, so elegantly simple? If I knew the answer, it would probably tell me something very deep about the nature of physical laws. But I don’t know.

cuando un cálculo confirma las propias expectativas, uno simplemente se reafirma un poco en su comprensión intuitiva de las leyes de la física. Pero cuando un cálculo contradice las expectativas, uno está en el camino hacia una nueva intuición.
