However, it is hypothesized that light entering a singularity would similarly have its geodesics terminated, thus making the naked singularity look like a black hole. [19] [20] [21] Disappearing event horizons exist in the Kerr metric, which is a spinning black hole in a vacuum, if the angular momentum () is high
The parameters of the singularity are M=1, a²+Q²=2M². The singularity is viewed from its equatorial plane at θ=90° (edge on). Comparison with an extremal black hole with M=1, a²+Q²=1M². Disappearing event horizons exist in the Kerr metric, which is a spinning black hole in a vacuum.
The singularity at the center of a Schwarzschild black hole is an example of a strong singularity. Space-like singularities are a feature of non-rotating uncharged black holes as described by the Schwarzschild metric , while time-like singularities are those that occur in charged or rotating black hole exact solutions.
A black hole is a region of spacetime where gravity is so strong that no matter or electromagnetic radiation, ... black hole, it is possible to avoid the singularity.
An observer falling into a Kerr black hole may be able to avoid the central singularity by making clever use of the inner event horizon associated with this class of black hole. This makes it theoretically (but not likely practically) [ 2 ] possible for the Kerr black hole to act as a sort of wormhole , possibly even a traversable wormhole.
There is no evidence that the electron is a black hole (or naked singularity) or not. Furthermore, since the electron is quantum-mechanical in nature, any description purely in terms of general relativity is incomplete until a better model based on understanding of quantum nature of black holes and gravitational behaviour of quantum particles ...
For black holes, this manifests as Hawking radiation, and the larger question of how the black hole possesses a temperature is part of the topic of black hole thermodynamics. For accelerating particles, this manifests as the Unruh effect, which causes space around the particle to appear to be filled with matter and radiation.
Any event inside the black hole interior region will have a future light cone that remains in this region (such that any world line within the event's future light cone will eventually hit the black hole singularity, which appears as a hyperbola bounded by the two black hole horizons), and any event inside the white hole interior region will ...
