👉 In physics, a breakoff is an abrupt transition or change in state between two states. It refers to a point at which one system of particles (the "break" part) begins to occupy space and another system (the "breakaway" part) becomes stationary. The term was introduced by physicist Eugene Wigner in his 1937 paper "On the Breakoff of Particles". The breakoff hypothesis posits that this transition between two states can occur spontaneously without any external influence
