Abstract

In this paper the various “presence of matter” and “absence of matter” conditions, in gravitational field regions, of the vacuum of space-time, in the General Relativity (GR) Einstein Field Equations (EFEs) is discussed. The Static & Dynamic Vacuum Solutions of the (EFEs) and the various conditions are discussed using simplified ** Classical Mathematics and Mechanics**.

Predicted in the various “absence of matter” or “presence of matter” conditions of the (EFEs), “empty space” is shown to be filled with “Electromagnetic Heat Radiation Energy” or “Dark Expansion Space Energy” in gravitational field regions, of the vacuum of space-time, where there is no mass present in that location. Furthermore, it will be validated in the mathematics, of General Relativity (GR), and the Einstein Field Equations (EFEs), that the solution of the Black Hole Event Horizon, describes the maximum curvature, and the smallest, infinitesimal, most minimum space-time distance, of a gravitational field.
