Interesting article as Ethan Siegel tackles several black hole questions.
"How is angular momentum conserved when stars collapse to black holes?
What does it mean for a black hole to spin?
What is actually spinning?
How can a singularity spin?
Is there a "speed limit" to this spin rate and how does the spin
affect the size of the event horizon and the area immediately around
I won't spoil the article by quoting, but the conclusion reached at
the end is worth the effort. :)
