Cosmic Microwave Background Fluctuation Amplitude from Dark Energy   De-Coherence
  Standard cosmology connects the scale generated at late times by the cosmological constant with that generated in early times by the energy dynamics. Assuming dark energy de-coherence occurs during early times when the scale parameter expansion rate is no longer supra-luminal specifies a class of cosmological models in which the cosmic microwave background fluctuation amplitude at last scattering is approximately $10^{-5}$.
