Complementarity of Gravitational Collapse (I) Origin of the Bekenstein-Hawking Entropy

Abstract

Through two exact solution families to Einstein equation and one-to-one correspondence between their free parameters, we show that the ensemble of collapsars with arbitrarily close-to-implementing horizon in the Schwarzschild time definition and the over-cross-oscillatory solid-ball ergodically experiencing all possible modes in the Lemaître time definition constitute two complementary description for the inner structure of black holes formed through gravitational collapse. As a support for this complementarity, we prove that the area law formula of Bekenstein-Hawking entropy by counting the degeneracy of collapsing material's wave functional directly. In two companion works, observational signals of this inner structure picture will be reported independently.
