This question is about the relationship between information, entropy and heat.
I think it was in the 1970's the Hawking claimed "information is lost in black hole evaporation". This did not mean it was just inaccessible, but that it has literally disappeared, gone forever.
In the Black Hole War, Leonard Susskind 2008, pg 23 discusses when he first realized this must be wrong:
So assuming there IS information sitting in a black hole why is heated generated
when it evaporates? Is the existing heat with the black hole "released" beyond the event horizon and exposed so we can observe its effects...is that what Susskind is getting at?? And if so was all the "hidden stuff" necessarily so hot before it became a black hole..doesn't seem so.

What's so bad about losing a bit of information in a balck hole? Then it dawned on us. Losing information is the same as generating entropy. The virtual black holes that Stephen had so blithly postulated would create heat in empty space. . We (estimated)..that if Stephen were right empty space would heat up to a thousand billion billion billion degrees in a tiny fraction of a second.
