We prove that quantum effects, Hawking effect together with Shwinger effect inevitably lead to violation of cosmic censorship.

Curvature, torsion and non-metricity are geometric trinity. F(T) theory modifies the metric teleparallel gravity. We constructed a thick brane model in f(T) theory. Tensor perturbations are analyzed and the localization of graviton zero mode is studied. Besides, we also studied the quasinormal modes of f(T) thick brane and gravitational echos can also be found.

The inaccessibility of a black hole’s internal structure, due to the one-way nature of the event horizon, remains a fundamental challenge in astrophysics. Nevertheless, gravitational interactions can bridge our understanding between the black hole’s internal structure and the external spacetime. Specifically, the spacetime structure is characterized by its multipole moments, which vary...

20. Complete quasinormal modes of Type-D black holes

Changkai Chen

We developed a revolutionary new method to precisely calculate the full spectrum of vibrations (quasinormal modes, QNMs) emitted by black holes after collisions. This solves two major, decades-old theoretical puzzles: 1. The Spin Discrepancy Solved: The apparent discontinuity between spinning (Kerr) and non-spinning (Schwarzschild) black hole vibrations as the spin vanishes (a → 0) is an...
