RC_BEC – Emergence of Spacetime Grains via Chronological Rule (RC) in Universal Condensate

We propose a theoretical framework in which spacetime emerges from a universal condensate through a 'Chronological Rule' (RC). Each spacetime grain is stitched to at least one pre-existing grain if coherence surpasses a threshold θ. At the limit T → 0, the rule predicts an operational disappearance of measurable signals across independent detection channels. This prediction allows an experimental falsification using Bose–Einstein condensates (BEC) and ultracold solids. The theory provides a minimal effective description of spacetime emergence and suggests a testable pathway connecting quantum coherence to macroscopic reality.
