Spacetime Foam Model of the Schwarzschild Horizon
arXiv:gr-qc/0307025 · doi:10.1103/PhysRevD.69.124008
Abstract
We consider a spacetime foam model of the Schwarzschild horizon, where the horizon consists of Planck size black holes. According to our model the entropy of the Schwarzschild black hole is proportional to the area of its event horizon. It is possible to express geometrical arguments to the effect that the constant of proportionality is, in natural units, equal to one quarter.
