Roberto Casadio, Alexander Kamenshchik, Jorge Ovalle
TL;DR
This paper explores cosmological models derived from a revisited Schwarzschild black hole, revealing they form a Kantowski-Sachs universe with detailed analytical solutions and insights into singularity features.
Contribution
It provides an explicit analytical example of a Kantowski-Sachs universe from a revisited Schwarzschild black hole and analyzes its singularity characteristics.
Findings
The solutions describe a non-trivial Kantowski-Sachs universe.
An explicit analytical example with detailed features is provided.
Insights into the nature of the singularity are discussed.
Abstract
We study cosmological models based on the interior of the revisited Schwarzschild black hole recently reported in [Phys.~Rev.~D{\bf 109} (2024) 104032]. We find that these solutions describe a non-trivial Kantowski-Sachs universe, for which we provide an explicit analytical example with all the details and describe some general features of the singularity.
