Abstract
Pregeometric gravity investigates the nonmetric features of spacetime near the Planck scale, from which the gravitational interaction arises as a low-energy effective theory via a mechanism of spontaneous symmetry breaking. With a view of amending the classical singularities found in black hole geometries, in this work we study pregeometric black hole configurations with spherical symmetry, and present exact solutions for different pregeometric theories in vacuum via the correspondence principle. These solutions are the pregeometric analog of the (anti–)de Sitter-Schwarzschild metric, from which such type of black hole geometry is thus expected to emerge. In one case, the pregeometric solution also exhibits an (anti–)de Sitter core of Planckian size. The main result is supplemented with an analysis of the pregeometric version of Birkhoff’s theorem.
