Intrinsic brightness of SDSS objects is similar at all redshifts in de Sitter space

TL;DR

This paper compares SDSS galaxy and quasar data under Hubble and de Sitter redshift models, finding that a de Sitter universe implies consistent intrinsic brightness across all redshifts, contrasting with the luminosity evolution suggested by Hubble's model.

Contribution

It introduces the idea that a de Sitter redshift model can explain SDSS data with uniform intrinsic brightness, challenging the conventional Hubble-based interpretation.

Findings

De Sitter redshift implies similar intrinsic brightness at all redshifts.

95% of SDSS objects fall within a 2.8 magnitude range in de Sitter space.

Hubble redshift interpretation shows a much larger luminosity range.

Abstract

The redshift-luminosity distributions for well-defined galaxies and quasars in the Sloan Digital Sky Survey (SDSS) are compared for the two redshift-distance relations of a Hubble redshift and a de Sitter redshift. Assuming a Hubble redshift, SDSS data can be interpreted as luminosity evolution following the Big Bang. In contrast, given a de Sitter redshift, the intrinsic brightness of objects at all redshifts is roughly the same. In a de Sitter universe, 95 per cent of SDSS galaxies and quasars fall into a magnitude range of only 2.8, and 99.7 per cent are within 5.4 mag. The comparable Hubble luminosity ranges are much larger: 95 per cent within 6.9, and 99.7 per cent within 11.5 mag. De Sitter space is now widely discussed, but the de Sitter redshift is hardly mentioned.
