Acceleration of cosmic expansion through huge cosmological constant progressively reduced by submicroscopic information transfer

TL;DR

This paper proposes a model where the decay of dark energy density and information transfer in a multiverse context explain the accelerated cosmic expansion, aligning with standard scalar field cosmology.

Contribution

It introduces a novel mechanism where information transfer delays cause a friction-like effect, reducing the cosmological constant's influence over time.

Findings

Decay of dark energy density by a factor of 10^{-120}

Expansion velocity increases over time, but is impeded by information transfer delays

Model aligns with standard scalar field cosmological solutions

Abstract

In a previous paper (Ref. [1]) the presence of dark energy in our universe was explained as the fingerprint of a comprehensive, much older and expanding multiverse with positive spatial curvature, whose space-time is spanned by this energy, and which was created out of nothing. This concept is expanded by the addition of a model for explaining the decay of the mass density $\varrho$ of dark energy from its origin until now by a factor of approximately $10^{-120}$. Elementary particles contain information about which laws of nature they obey, but not what exactly these are. Most likely, the laws are not followed by obedience to a categorical imperative. Rather, it is assumed, that from the very beginning the information about them is coded in submicroscopic patches of the space-time. The initial density $\varrho_i$ is supposed to belong to the unimpaired cosmological constant obtained from elementary particle theory. Due to its huge value it causes an extremely fast spatial expansion by which continuously new space-time elements are created. To them, the information about the physical laws must be transmitted from the already present space-time. This process needs time which with ever-increasing expansion velocity is getting scarcer and scarcer. It is concluded that this impedes the expansion through a friction-like process which can be described by a term proportional to the expansion-velocity. This term is subtracted from the expansion-acceleration. It is shown that the solutions thus obtained are also solutions of the cosmological standard equations employing a scalar field $\Phi$. In consequence, the present model can be considered as a re-interpretation of results which can be obtained with acknowledged methods.
