::'''Re: #24.'''  The second law of thermodynamics only applies to closed systems.  In the case of stellar black hole formation, gravitational pressure must exceed the sum of the thermal pressure, supplied by ongoing fusion in the stellar core, and the core degeneracy pressure, provided courtesy of the Pauli exclusion principle.  Achieving this condition is, necessarily, a very violent event, complete with giant explosions, gamma ray bursts, and spewing jets of super-heated gas.  When considering the entirety of the system giving rise to a black hole, and not just the resulting black hole itself, entropy certainly ''does'' increase. --[[User:RudrickBoucher|RudrickBoucher]] 23:19, 8 January 2012 (EST)

:::Hello! Thanks for the comments.  And sorry about #24, like I said, the model I gave is slightly idealized b/c I haven't studied the subject in detail. [[User:AndyFrankinson|AndyFrankinson]] 07:58, 9 January 2012 (EST)
