Definition. A subatomic particle is a unit of matter or energy that's the fundamental makeup of all matter. According in modern atomic theory, an atom has a nucleus, which is its center, or core. The nucleus contains subatomic particles: protons and neutrons. Protons are positively-charged particles. Neutrons are neutral particles. Surrounding the nucleus is a cloud of very small subatomic particles, called electrons. Electrons are negatively-charged particles.
The Schwarzschild radius of a black hole is the distance from the singularity (center) to. the point where the gravitational field becomes zero. the event horizon, from which light cannot escape. the outside radius of the massive solid body forming the black hole.. The black hole modifies spacetime around it so much that particles and X-rays are created in the vacuum itself, just outside the event horizon. The X-rays are produced by vibrations of the black hole itself, and therefore they come from the event horizon, and not from inside the black hole.
