In 1916 Karl Schwarzchild found a solution to the field equations of relativity which predicted a special distance from the black hole called the Schwarzchild radius, but is also known as the event horizon, beyond which nothing can escape.
A classical field theory is a physical theory that predicts how one or more physical fields interact with matter through field equations. The term 'classical field theory' is commonly reserved for describing those physical theories that describe electromagnetism and gravitation, two of the fundamental forces of nature. Theories that incorporate quantum mechanics are called quantum field theories.
