Alternate Models to Dark Energy

TL;DR

This paper proposes alternative models to explain the universe's accelerated expansion observed through Type Ia supernovae, challenging the dark energy paradigm in cosmology.

Contribution

It introduces new models that account for supernovae data without relying on dark energy, offering a different perspective on cosmic acceleration.

Findings

Models successfully fit supernovae data without dark energy

Provides a potential alternative explanation for cosmic acceleration

Challenges the necessity of dark energy in cosmological models

Abstract

One of the unresolved questions currently in cosmology is that of the non-linear accelerated expansion of the universe. This has been attributed to the so called Dark Energy (DE). The accelerated expansion of the universe is deduced from measurements of Type Ia supernovae. Here we propose alternate models to account for the Type Ia supernovae measurements without invoking dark energy.
