Let's say we try to remove the event horizon of a Kerr black hole by throwing in matter with some large angular momentum. If it starts with GM > a, could we increase a at all? Would such a particle be able to enter the black hole?

• There's no known process by which this can happen using non-exotic matter without having the additional angular momentum end up being shed off in the form of gravitational radiation. May 2, 2014 at 15:47
