Black Holes With Complete Asymptotic Throats
Yi-Bo Liang, Hong-Rong Li
We investigate whether a spherically symmetric black hole can have a complete inner end at finite, nonzero areal radius while satisfying the standard energy conditions sufficiently…
Asymptotic Throat: The Geometric Inevitability of Regular Black Holes
Yi-Bo Liang, Hong-Rong Li
We reveal that a fundamental minimal length naturally replaces the Schwarzschild singularity with future infinity, formalizing the ``asymptotic throat'' as a geometric inevitabilit…
The Globally Trapped Future: A Fate for Black Holes and Wormholes
Yi-bo Liang, Hong-Rong Li
We demonstrate, for the first time, that arbitrary spherically symmetric metrics can be derived within a framework based on the coupling of two scalar fields and an electromagnetic…
Regular Power-Maxwell Black Holes
Yi-bo Liang, Hong-Rong Li
We present a new class of regular, spherically symmetric spacetimes in nonlinear electrodynamics that are asymptotically dynamical but not de Sitter, exhibiting power-law Maxwell b…
Rationalizing Unphysical Radiation in the Unruh Effect by Extending Black Hole Spacetime
Yi-Bo Liang, Hong-Rong Li
We demonstrate that Schwarzschild spacetime has a conformal extension and that, beyond null infinity, there is a black hole with a timelike singularity. In conformal extended space…
