Entropy in the interior of a black hole and thermodynamics (1510.02182v1)
Published 8 Oct 2015 in gr-qc
Abstract: Based on a recent proposal for the volume inside a black hole, we calculate the entropy associated with this volume and show that such entropy is proportional to the surface area of the black hole. Together with the consideration of black hole radiation, we find that the thermodynamics associated with the entropy is likely to be caused by the vacuum polarization near the horizon.
