Temporal Asymmetry (Theorem V*)

arrow of timetheorem V*indestructibility of past

Definition

Theorem V* of ODTOE establishes temporal asymmetry of past and future states in H: the past is indestructible (norm conservation under Φ-iterations), the future is constructible (not fixed). Projectors π_past and π_future are mutually orthogonal, which gives the arrow of time from first principles and connects to Penrose's CCC and Wheeler's delayed-choice.
