What exists between a black hole's event horizon and its singularity?

Question

Lincoln Adams · Accepted Answer

We can't be sure what exists between the event horizon and singularity of a black hole.

What occurs inside a black hole is beyond the scope of what we currently understand about the laws of physics. By definition, nothing can escape from inside the vent horizon, not even light, which leads to an issue called the information paradox: information about an object is lost if it falls through the event horizon, which is not permitted. Stephen Hawking is developing a theory that the information about the object gets stored in the event horizon itself, which would circumvent the information paradox. A singularity, or point of infinite curvature of space time and infinite density, is predicted by general relativity to exist inside a black hole. Infinities are a problem in mathematics and physics, and new physics is needed that may be able to eliminate the infinities. Whatever passes the event horizon eventually joins the singularity, and since we can never see inside a black hole, we can never know what is inside. According to our best theories, there are objects that have crossed the event horizon and are moving toward the singularity between it and the singularity.

undefined Extreme gravitational forces and intense spacetime curvature characterize the region known as the black hole's interior or central core, which is located between the event horizon and the singularity of the black hole.
