### Class subject: Black Hole Structure.

 These parts collectively form the intricate structure of a black hole, shaping its gravitational field and influencing the behavior of surrounding matter and energy in the cosmos: 1. Singularity: The singularity is the core of a black hole, where the mass is concentrated to an infinitely small point. It is surrounded by an event horizon, beyond which nothing can escape, not even light. 2. Event Horizon: The event horizon is the boundary surrounding the singularity of a black hole. Once an object crosses the event horizon, it is inexorably pulled into the black hole's gravitational grip. The escape velocity at the event horizon exceeds the speed of light, making it the point of no return in the gravitational field of the black hole. 3. Photon Sphere: Located just outside the event horizon, the photon sphere is a region where photons (particles of light) can orbit the black hole. Photons traveling along certain paths in this region can become trapped in unstable orbits, creating a luminous ring around the black hole. 4. Ergosphere: The ergosphere is an oblate spheroid region surrounding a rotating black hole, where spacetime is dragged along with the black hole's rotation. Objects within the ergosphere are forced to move in the direction of the black hole's rotation, potentially gaining energy in the process. 5. Accretion Disk: The accretion disk is a swirling disk of hot gas, plasma, and other matter orbiting around a black hole. As matter falls towards the black hole, it forms a disk due to conservation of angular momentum. The intense gravitational forces and friction within the disk cause it to heat up, emitting powerful radiation across the electromagnetic spectrum. 6. Jet Streams: Jet streams are narrow, high-energy beams of particles and radiation ejected from the vicinity of a black hole's poles. These jets are formed by the acceleration and compression of matter in the accretion disk, channeled along magnetic field lines and propelled outward at nearly the speed of light. 7. Hawking Radiation (Theoretical): Hawking radiation is a theoretical form of radiation predicted by physicist Stephen Hawking. According to quantum mechanics, pairs of virtual particles are constantly being created and annihilated near the event horizon of a black hole. In certain cases, one particle falls into the black hole while the other escapes, resulting in a net loss of mass for the black hole and the emission of radiation.
