Abstract This paper introduces the Neopt particle as the fundamental agent of cosmic continuity, replacing the Big Bang paradigm with a model of eternal fusion. The Neopt is defined as a spin‑2 boson carrying a unique quantum property: eternalmemory, encoded through a non‑Markovian interaction with a living wave‑lattice fabric. Its dynamics are governed by an extended Lindblad equation, and gravity emerges as a memory‑induced correlation between particles sharing an origin code. Cosmic expansion is reinterpreted as continuous information–energy injection driven by Hawking radiation. Three testable predictions distinguish this model from Newtonian gravity and General Relativity.
