The Arrow of Time as an Intrinsic Property of Quantum Gravitational Collapse

The origin of time's arrow---the asymmetry between past and future---remains unexplained within time-reversal-symmetric fundamental physics. We argue that the arrow of time is not a consequence of special initial conditions or entropy gradients but an intrinsic feature of quantum gravitational collapse. Each collapse event irreversibly converts quantum superposition into classical definiteness, creating a monotonically increasing record of information that defines the direction of time. In this
