The Black Hole Event Horizon as a Limited Two-Way Membrane

It is shown that under a set of straightforward propositions there exists, at the event horizon and at nonzero radii inside the event horizon of a nonrotating, uncharged, spherically symmetric black hole (BH), under reasonable curvature constraints, a nonempty set of virtual exchange particle modes which can propagate to the black hole’s exterior. This finding reveals that a BH event horizon is not a one-way membrane, but instead a limited two-way membrane. The paper’s technology also permits presentation of what is called virtual cosmic censorship, which requires that the aforesaid virtual exchange particle mode propagation tend to zero at the singularity limit.
