Cosmological Instantaneous Classicalisation

We introduce a promising, albeit speculative design, that peers through the spectrum of Cosmological Instantaneous Classicalisation by integrating the microphysics
of Loop Quantum Gravity (LQG) with the entropic framework of the Event Driven First Passage Model (EDFPM) and by extension the Entropic Bridge Model (EBM). We adopt three core axioms: (1) The microphysical stochasticity of quantum geometry, driven by a fundamental Poisson process on spin network edges, defines a universal frequency ω ≈ 10^43 Hz. This value is shown to be consistent with the Loop Quantum Cosmology (LQC) bounce timescale tb ∼ lPl/c. (2) The EBM’s entropic instability governs collapse via a hazard rate α = ω ln N (t), where N (t) counts the combinatorial degrees of freedom in the spin network boundary. (3) Cosmological N (t) scales holographically as N (t) ∝ (RH (t)/lPl)2, with horizon radius RH (t) ≈ ct. The unified model yields a mean collapse time ⟨T0⟩ = 1/α(t) ≪ 10−32 s during inflation, enforcing instantaneous classicalisation. This mechanism delivers the classical, universe essential for Big Bang Nucleosynthesis (BBN), addressing a central dilemma in cosmology.
