Assuming a black hole rotates about an axis. As more and more matter is absorbed by the black hole and there is no reduction in rotation speed would there come a time when the "equator" approaches the speed of light? Our understanding of forces means that the particles could not exceed the speed of light and the black hole would become less spherical and more shaped like a rugby ball. To extrapolate further there would come a time when the "North and South" of the black hole would emit energy as the particles escape the gravitational field. Like an ice skater spinning when they bring their arms in the rotation speed increases the black holes rotation speed should also increase. This would fuel more particles to be emitted North and South. There is also a case for Hawking radiation at the equator. Opinions please.
