Witryna1 lut 2009 · The known laws of physics are clear that a singularity forms, but they are hazy about the event horizon. ... A naked singularity would be a "quantum star," a …
In general relativity, a naked singularity is a hypothetical gravitational singularity without an event horizon. In a black hole, the singularity is completely enclosed by a boundary known as the event horizon, inside which the curvature of spacetime caused by the singularity is so strong that light cannot escape. Hence, … Zobacz więcej From concepts drawn from rotating black holes, it is shown that a singularity, spinning rapidly, can become a ring-shaped object. This results in two event horizons, as well as an ergosphere, which draw closer … Zobacz więcej Disappearing event horizons exist in the Kerr metric, which is a spinning black hole in a vacuum. Specifically, if the angular momentum is high enough, the event horizons could disappear. Transforming the Kerr metric to Boyer–Lindquist coordinates, … Zobacz więcej • M.

LIGO events, including GW150914, are consistent with these predictions.

We investigate how the complexity=anything observables proposed by [ arXiv:2111.02429, arXiv:2210.09647] can be used to investigate the interior geometry of AdS black holes. In particular, we illustrate how the flexibility of …
