Gauge-Dependent Cosmological "Constant"
Bahram Mashhoon, Paul S. Wesson
TL;DR
This paper demonstrates that in 5D induced-matter gravity, a gauge transformation can turn a constant cosmological term into a variable one, affecting cosmological evolution and galaxy formation.
Contribution
It introduces a gauge-dependent approach to the cosmological constant within 5D gravity, showing its variability over cosmic time.
Findings
The cosmological constant becomes infinite at the big bang.
It decays to a value compatible with current observations.
Implications for cosmology and galaxy formation are discussed.
Abstract
When the cosmological constant of spacetime is derived from the 5D induced-matter theory of gravity, we show that a simple gauge transformation changes it to a variable measure of the vacuum which is infinite at the big bang and decays to an astrophysically-acceptable value at late epochs. We outline implications of this for cosmology and galaxy formation.
