Version 3 - Gravitational Memory and Cosmic Self-Observation: A Scalar Field Approach

This updated version presents an extended theoretical framework where rotating black holes act as dynamic gravitational sensors, analogous to optical systems. We formalize their role as active transducers of information, extracting energy via the Blandford–Znajek mechanism and emitting directional memory through relativistic jets. These jets couple back to a cosmological scalar field phi(x,t), interpreted as a memory field encoding gravitational history. A new dynamical equation with a directional coupling term is introduced. The model suggests that the universe may function as a distributed, self-observing system. Observational tests involving polarization (EHT, VLBI) and galaxy-scale feedback (JWST, Euclid) are proposed. This version also includes a new Annex F and updated conclusions on the epistemological implications of a self-regulating cosmology.
