We propose a universal inequality that unies the Bousso bound with the classical focussing theorem. Given a surface that need not lie on a horizon, we dene a nite generalized entropy Sgen as the area of in Planck units, plus the von Neumann entropy of its exterior. Given a null congruence N orthogonal to , the rate of change of Sgen per unit area denes a quantum expansion. We conjecture that the quantum expansion cannot increase along N. This extends the notion of universal focussing to cases… Expand
