CMB fluctuation amplitude from dark energy partitions

Abstract

It is assumed that the dark energy observed today is frozen as a result of a phase transition involving the source of that energy. Postulating that the dark energy de-coherence which results from this phase transition drives statistical variations in the energy density specifies a class of cosmological models in which the cosmic microwave background (CMB) fluctuation amplitude at last scattering is approximately 10 −5 .PACS numbers: 98.80. Bp, 98.80.Jk, 95.30.Sf In a previous paper (reference [1], equation 14), it has been shown that the fluctuation amplitude of the Cosmic Microwave Background (CMB) can be theoretically estimated to be of the order 10 −5 , in agreement with observational evidence, using a minimal set of assumptions. Although the scale parameter of the cosmological expansion at the time of dark energy de-coherence (as defined in reference [1]) enters the calculation, the final result depends only on the normalized dark energy density Ω Λ , the red shift at last scattering z LS , and the red shift at the time when the energy density of the non-relativistic pressure-less matter observed today was equal to the radiation energy density z eq . The observation that the final result was independent of any specifics at the time of de-coherence suggested to the authors of this paper that *

Evidence for a Cosmological Phase Transition on the TeVScale

“…The basic assumption in this paper is that the quantum zero-point energies whose effects on the subsequent cosmology are fixed by the phase transition mentioned in the previous paragraph are to be identified with the cosmological constant, or "dark energy". It has been shown elsewhere [9] that the expected amplitude of fluctuations driven by dark energy as the energy density de-coheres is of the order needed to evolve into the fluctuations observed in CMB radiation and in galactic clustering. From the time of this phase transition until this scale factor expansion rate again becomes supra-luminal due to the cosmological constant, the usual expansion rate evolution predicted by FL dynamics, including a cosmological constant, is expected to hold.…”

“…As an intuitive guide into how dark energy might freeze out as as system de- state, one should be able to use counting arguments to quantify these variations [9,20].…”

“…An interacting sea of the quantum fluctuations due to zero point motions should exhibit local statistical variations in the energy. For a sufficiently well defined phase state, one should be able to use counting arguments to quantify these variations [9,20].…”

Consequences of a Cosmological Phase Transition at the TeV Scale

“…Statistical arguments can be made (17,18) which infer that the dark energy E is expected to have uniform density, and to drive fluctuations of the order…”

Scientific Eschatology

“…On the Silver Jubilee of the founding of the Alternative Natural Philosophy Association it was possible to present a new piece of natural philosophy [1,2,3] which the authors believe has profound implications for the new field of particle-astrophysics/cosmology; SLAC has recently made this discipline an important part of its mission. What follows is a discussion of a few of the important questions raised by the future implications of this cosmology if it, and other cosmologies which share with it a positive "cosmological constant", survive the rigorous scientific scrutiny they are now receiving.…”
