How do black holes fit into the scheme of "heat death" or max entropy.
gpt
A black hole has the maximum possible entropy that can fit into a given region of space (the Bekenstein bound). If you think about all the possible configurations of the star prior to the black hole, and then that a black hole only has three properties (mass, charge, and spin), you can see that a black hole is the macrostate with the most possible microstates.
