Rewinding the Void: How One Solution of Einstein's Field Equations Describes Both the Birth of a Universe and the End of Time
Charles W. Robson, Marco Ornigotti
The type D Kasner vacuum solution of general relativity is reviewed, highlighting the little-known, intriguing property that it can describe both an anisotropic cosmology and the s…
Take the A-Metric: Interpretations of Some Known Solutions of Einstein's Vacuum Field Equations
Charles W. Robson, Marco Ornigotti
In this work, we present a new interpretation of the only static vacuum solution of Einstein's field equations with planar symmetry, the Taub solution. This solution is a member of…
Hidden Depths in a Black Hole: Surface Area Information Encoded in the (,) Sector
Charles W. Robson, Marco Ornigotti
Based on an investigation into the near-horizon geometrical description of black hole spacetimes (the so-called "(,) sector"), we find that the surface area of the event hori…
The Hawking Temperature of Anti-de Sitter Black Holes: Topology and Phase Transitions
Charles W. Robson, Leone Di Mauro Villari, Fabio Biancalana
In this work we determine how the description of a four-dimensional Schwarzschild-anti de Sitter black hole affects the topological calculation of its Hawking temperature. It is sh…
Global Hawking Temperature of Schwarzschild-de Sitter Spacetime: a Topological Approach
Charles W. Robson, Leone Di Mauro Villari, Fabio Biancalana
We introduce a calculation, based on purely topological reasoning, of the global equilibrium Hawking temperature of the Schwarzschild-de Sitter spacetime, where a Schwarzschild bla…
On the Topological Nature of the Hawking Temperature of Black Holes
Charles W. Robson, Leone Di Mauro Villari, Fabio Biancalana
In this work we determine that the Hawking temperature of black holes possesses a purely topological nature. We find a very simple but powerful formula, based on a topological inva…
