Black hole entropy counts the degrees of freedom of something unclear
Investigate common characteristics
of general theories of gravity

Identifying the canonical conjugate of Wald entropy from the action
In the classical limit (specific heat )
Non zero uncertainty at
the opening angle
Quantum black hole is expected to be super-position of metrics with conical singularities.
In string theory the “microstates“ of the black hole are metrics with (quantized) conical singularities at the horizon.
