👉 Divergence is a concept in physics, particularly in quantum mechanics and general relativity, which refers to the state of an object or system as it changes from one state to another. It can also refer to the difference between two states or values in a system. For example, if an object has two different states (e.g., a black hole and a white hole) with respect to time, then the divergence of that object's energy would indicate how much energy is lost as time passes through
