Unformatted text preview: 1. These are detected by observing the motions of material around the black hole 2. A nonrotating black hole has only a center and a surface 3. The entire mass of a black hole is concentrated in an infinitely dense singularity 4. The singularity is surrounded by the event horizon 5. Just three numbers completely describe the structure of a black hole 6. The three physical properties are: mass, electric charge, and angular momentum 7. A rotating black hole (one with angular momentum) has an ergoregion around the outside of the event horizon 8. In the ergoregion, space and time themselves are dragged along with the rotation of the black hole...
