Abstract:
	The gravitational pull of a black hole attracts gas and forms a
physical laboratory whose extreme conditions cannot be replicated on Earth.
The infalling gas forms an accretion disk where the interplay between
hydromagnetic processes and the warping of space-time releases
gravitational energy in the form of radiation, relativistic jets, and
winds. It is likely that most gas falls into black holes when the accretion
rate approaches the Eddington limit, at which point radiation pressure
