Black holes are one of the most interesting phenomena in space, and the answer may provide insight to the nature of a black hole.

Black holes are made by a curvature in the gravitational field, which is formed by a super dense kind of matter. Its gravitational force is so strong that all real particles, even light carrying photons, get attracted to it. This causes anything with mass to be extremely attracted to the black hole, since its almost infinite mass creates a force just as large. With this notion, you would need a force greater than this gravitational force to take the black hole apart. Although this seems impossible, gravity is the weakest of nature's four fundamental forces, so we will use these other forces to attempt this problem.

First, a way to counteract the inward force of the gravity is by rotating the object as much as possible . This rotation supplies a centrifugal force outward from the black hole, and this outward force is able to counteract the inward gravitational force. Additionally, if we were to add enough charge to the black hole, where like charges repel each other, enough repelling charges would be able to supply a large enough electromagnetic force, capable of causing the black hole to explode, or just come apart.

Being able to add centrifugal force outward and electromagnetic force outward, by adding angular momentum and charge, we COULD counteract the forces of a black hole. This would cause the black hole to come apart, effectively freeing the particles that previously made up the thing.

Realistically, however, we could not get close enough to a black hole to supply charge or angular momentum. Black holes are as massive as galaxies, and it would take a lot of charge and a lot of rotational energy. Theoretically though, it is possible.

Hope this answers your question!

According to the theory of general relativity, which is our best theory that currently describes black holes (see below), all of the matter in a black hole is confined to zero volume. If the black hole is rotating, this zero volume "space" will be a ring, but if the black hole is not rotating, it will be a point at the very center of the event horizon. The event horizon of any black hole will be a perfect sphere regardless, but the rotating black hole will actually have a smaller event horizon than a nonrotating one relative to its energy. I do not know how energy of the the black hole's rotation factors into this.

We do not have a quantum mechanical description of black holes. According to quantum mechanics, the infinitely small "space" where the black hole's mass is located is impossible. One of the two theories must break down at that scale.
