Operational Causal Witnesses in Kinematic Space Explained

Explore how operational causal witnesses map cause‑and‑effect into kinematic space, why causal order alone lacks scale, and whether the weighted shape of witness loci encodes spacetime curvature. The video walks through probing spacetime with causal diamonds, distinguishes signaling from correlation, builds witness loci via order, operational, and weight layers, examines limits in holographic settings, and includes retrieval exercises.
