Webb15 sep. 2024 · In the context of the most general scalar–vector–tensor theory, we study the stability of static spherically symmetric black holes under linear odd-parity perturbations. We calculate the action to second order in the linear perturbations to derive a master equation for these perturbations. For this general class of models, we obtain …

Webb12 jan. 2016 · How to find a black hole. During star formation, gravity compresses matter until it is stopped by the star’s internal pressure. If the internal pressure does not stop the compression, it can result in the formation of a black hole. Some black holes are formed when massive stars collapse. Others, scientists believe, were formed very early in ... Webb26 maj 2024 · That is the conventional model in a nutshell—black holes, neutron stars, and white dwarfs are the corpses of dead stars. There are numerous problems with this theory, but none perhaps has been as unsettling to astrophysicists as the recent observation of supermassive black holes that reside at the edge of the visible universe and hence are …
