April 13, 2024. 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.

Do Naked Singularities Break the Rules of Physics?

WitrynaThis is the location of the inner event horizon. For the extremal black hole, Q = 0.5, the escape velocity rises to c at r = 0.5 r s but then falls again. There is a single horizon at r = 0.5 r s. Finally for the naked singularity Q = 0.6, the escape velocity never reaches c so there is no horizon. However something rather odd happens at small ...

Naked Singularities Can Actually Exist in a Three

Witryna15 lis 2010 · We generalize here our earlier results on particle acceleration by naked singularities. We showed recently [M. Patil and P. S. Joshi, Phys. Rev. D 82, 104049 (2010).] that the naked singularities that form due to the gravitational collapse of massive stars provide a suitable environment where particles could get accelerated … Witryna14 gru 2024 · 5. The big bang is certainly spacelike. If you use the definition in Penrose 1973, then the big bang is not a naked singularity. See pp. 85-86 of that paper. He defines a naked singularity as one that can be in both the past and future light cones of the same observer.
