De Sitter Special Relativity: Effects on Cosmology

TL;DR

This paper explores how de Sitter Special Relativity modifies the standard cosmological model, linking the cosmological constant to matter content and predicting inflation and observer modifications.

Contribution

It introduces a novel perspective where the cosmological constant arises from conformal currents, connecting it to matter content and providing estimations consistent with observations.

Findings

Cosmological constant linked to conformal current and matter content

Predicted a value of Lambda close to observational data

Identified a polynomial primeval inflation scenario

Abstract

The main consequences of de Sitter Special Relativity to the Standard Cosmological Model of Physical Cosmology are examined. The cosmological constant Lambda appears, in this theory, as a manifestation of the proper conformal current, which must be added to the usual energy-momentum density. As that conformal current itself vanishes in absence of sources, Lambda is ultimately dependent on the matter content, and can in principle be calculated. A present-day value very close to that given by the crossed supernova/BBR data is obtained through simple and reasonable approximations. Also a primeval inflation of polynomial type is found, and the usual notion of co-moving observer is slightly modified.
