Dynamic Event Horizon: The Effects of Tidal Gravitational Forces on Black Holes

AI Thread Summary
Tidal gravitational forces may alter the curvature of space around a black hole, suggesting that the event horizon could be a dynamic, wavy structure rather than a perfect sphere. The discussion highlights the complexity of space curvature and the limited exact solutions to the Einstein Field Equations, often relying on numerical approximations. While there is speculation that passing gravitational distortions could affect the event horizon, definitive proof is lacking. It is noted that any perturbation to the event horizon dissipates quickly, typically within seconds, due to the emission of gravitational waves. This rapid stabilization implies that the event horizon might resemble a spherical liquid with a wavy surface during transient states.

as "tidal gravitational forces" ripple outward, does that not change the curvature of space, making the region around the black hole very dynamic? so wouldn't the event horizon not be a sphere, but rather a wavy dynamic structure? because the "measured gravity" at a specific radius out at any given point would constantly change?

NOBODY knows? it has to be in the maths
 
Curvature of space is really quite complicated. In fact, we only have a handful of exact solutions to the Einstein Field Equations. Most of the time, people just work with numerical approximations. I have no first hand knowledge of whether passing gravitational distortions would affect the EH of a black hole. I would suspect that it would, but I really have no proof of this.
 
so wouldn't the event horizon not be a sphere, but rather a wavy dynamic structure?
I don't have the details at hand, but any perturbation of the EH fades away very quickly, by emitting gravitational waves. It's a matter of seconds for spacetime to calm down and the EH being spherical again.
 
if the math actually says it is a matter of seconds, then it would look sort of like a spherical liquid (if we could visualize the EH that is) with a wavy surface
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
