Do Laws of Physics Break Beyond the Event Horizon in Kerr Black Holes?

AI Thread Summary
The discussion centers on whether the laws of physics break down only at the singularity of Kerr black holes or if they also fail beyond the event horizon. The singularity is defined as a mathematical point of infinite density, while the event horizon is the boundary beyond which nothing, not even light, can escape. It is noted that quantum mechanics and general relativity remain valid beyond the event horizon. Additionally, the frame-dragging effect in Kerr black holes is suggested to continue towards the singularity, despite some conflicting visual representations of light paths. Overall, the conversation highlights the complexities of physics in extreme gravitational environments.

are all laws of physics break only at singularity Or laws of physics break even after event horizon?what is the difference

The singularity is the point (and it is important to understand that it is a mathematical point -- it has no dimensions) at which density becomes infinite. Clearly, shoving anything into zero volume will produce an infinite density. This is where modern physics begin to have a problem.

The event horizon, on the other hand, is a fictitious radius around the black hole at which not even light would be able to escape in any fashion. This represents a "point of no return" because, as nothing can travel faster than light, nothing can escape the fate of falling into the black hole beyond this radius.

Is quantum mechanics valid beyond event horizon?
 
Yes, so is general relativity.
 
In respect of Kerr black holes, I'm assuming the frame-dragging effect would also carry on beyond the event horizon towards the singularity. I would normally assume this was the case though I've seen some images of light paths that show the light/frames entering the black hole perpendicular to the event horizon regardless of the extremity of the frame-dragging.

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...
