	Timeline of black hole physics - Wikipedia, the free encyclopedia
		1969 - Roger Penrose discusses the Penrose process for the extraction of the spin energy from a Kerr fl hole
		1972 - James Bardeen, Brandon Carter, and Stephen Hawking propose four laws of fl hole mechanics in analogy with the laws of thermodynamics
		2002 - Astronomers present evidence for the hypothesis that Sagittarius A* is a supermassive fl hole at the centre of the Milky Way galaxy

	Black Hole Thermodynamics
		We imagine a fl hole as the singularity in the center surrounded by a spherical event horizon.We know that when a fl hole is created by a collapsing neutron star that the neutrons are crushed out of existence; by this I mean that all their neutronness is wiped out.
		Above we mentioned the Black Hole Has No Hair theorem, which states that no matter what falls into a fl hole, the only properties that remain are the total mass, charge, and angular momentum of the object.
		After it falls into the hole, however, we have seen that the description of its mass-energy becomes a combination of the possible standing wave states that can exist with nodes on the event horizon.

	Black Hole Evaporation and Information Loss (Site not responding. Last check: 2007-10-24)
		The lower the mass of a fl hole, the higher the energy of the emitted Hawking radiation.
		As a fl hole radiates, its mass decreases, and it starts emitting more and more radiation, causing it to evaporate more and more rapidly.
		Another proprosal is that fl hole evaporation ends with a massive remnant, and that all the information about how the fl hole was formed is somehow stuffed into this single Planck scale object.
