New Exact Black Hole Solutions Emerge From Gravity With a Twist of Torsion
Physicists have derived two exact black hole solutions in semi-symmetric metric gravity, a torsional extension of general relativity, and constrained ...
Quantum Forces May Halt Black Hole Collapse Before the Singularity Forms
A new theoretical analysis shows that quantum effects begin to strongly oppose gravitational collapse exactly at a discontinuous transition called ...
Physicists Unveil a Rotating Black Hole Solution That Exists Only Beyond Maxwell’s Electrodynamics
Researchers have constructed an exact rotating dilatonic black hole solution of Einstein–ModMax gravity that admits no Maxwell counterpart, with a ...
Black Hole Entropy Gets a New Twist as Cotton Gravity Passes the Thermodynamics Test
A new thermodynamic formulation shows that Cotton gravity modifies black hole and cosmological horizon entropy in a way that can ...
Hairy Black Holes in a Vector-Driven Universe Reveal How Cosmic Horizons Filter Hawking Radiation
Physicists have computed grey-body factors, absorption cross-sections and thermodynamic temperatures for de Sitter black holes whose cosmological scale and primary ...
Neutrinos Skirting Black Holes Could Reveal the Universe’s Hidden Dark Matter
A new theoretical study shows that dark matter surrounding black holes subtly alters neutrino flavor oscillations, offering a potential new ...
