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

In summary, the singularity is the point where density becomes infinite and modern physics begin to have a problem. The event horizon is a fictitious radius where not even light can escape, representing a "point of no return." Quantum mechanics and general relativity are valid beyond the event horizon, and in Kerr black holes, the frame-dragging effect may also continue towards the singularity. However, there are images that show light entering the black hole perpendicular to the event horizon regardless of the intensity of the frame-dragging.

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.

1. What are the laws of physics?

The laws of physics are fundamental principles that explain the behavior of matter and energy in the universe. They are based on mathematical equations and govern everything from the tiniest subatomic particles to the largest galaxies.

2. How do the laws of physics apply to black holes?

The laws of physics apply to black holes just as they do to any other object in the universe. However, the extreme conditions within a black hole, such as its immense gravitational pull and the presence of a singularity, can challenge our understanding of these laws.

3. What is the law of gravity and how does it relate to black holes?

The law of gravity states that any two objects with mass will attract each other. In the case of black holes, their immense mass creates a gravitational pull so strong that not even light can escape it. This is why black holes are often referred to as "gravity wells."

4. Can anything escape from a black hole?

According to current understanding and the laws of physics, nothing can escape from a black hole once it has passed the event horizon, which is the point of no return. This includes light, making black holes invisible to the naked eye.

5. How do black holes relate to the laws of thermodynamics?

The laws of thermodynamics, which govern the transfer of energy in a system, also apply to black holes. For example, the second law states that the total entropy (disorder) of a closed system will never decrease. This applies to black holes as well, as their entropy is directly related to their event horizon and the information it contains.
