Just as a point of reference: "The Black Hole War - My battle with Stephen Hawking to make the world safe for Quantum Mechanics" by Leonard Susskind. Basically Stephen Hawking said that information was lost in a black hole. This book outlines Susskind's search for a way to disprove that statement. His problem with the loss of information is that it would cause huge problems for QM.

C is the universal speed limit.
