<b>12.Gravitational Wave Echoes as Entangled Feedback</b>

This section demonstrates how gravitational wave echoes act as entangled feedback mechanisms rather than simple spacetime perturbations. Echoes originate from recursive collapse of causal regions in the entanglement lattice and reflect internal memory processing of the universe’s quantum structure. The A+M[S] model predicts waveform inversions, amplitude modulations, and frequency recurrences—patterns observed in LIGO/VIRGO data—stemming from structured entanglement decay. These echoes are not post-event ripples but encoded informational rebounds critical to structure formation and cosmological timing.
