Dark Energy as Emergent Stochastic Time Field Dynamics: Micro–Big Bangs, Wave-Lump Expansion, and the End of Λ

Dark energy, traditionally modeled as a cosmological constant (Λ) or a dynamical scalar field, is reimagined in the Time Field Model (TFM) as an emergent phenomenon driven by stochastic time wave dynamics. TFM posits that cosmic acceleration arises from micro–Big Bangs—quantum-scale energy bursts that generate space quanta—and entropy-driven expansion governed by time wave interactions. This framework elim inates Λ, predicting an oscillatory dark energy equation of state w(z) and unique observational signatures: • Hubble Tension Resolution: H0 ≈ 72kms−1Mpc−1 via entropy-coupled ex pansion. • Supernova Luminosity Deviations: δm(z) ≈ 0.02 sin(ωz), detectable around z ∼1. • Gravitational Wave Background: ΩGW(f) ∝ f−1/3, arising from micro–Big Bangs in the nHz–µHz range. TFM emphasizes testability and aims to unify dark energy, dark matter, and aspects of quantum measurement within a single stochastic framework.
