Observational Tests of Instanton Cosmology

TL;DR

This paper introduces a new cosmological model that makes distinct, testable predictions from standard models, notably achieving a zero deceleration parameter without exotic matter, challenging existing cosmological paradigms.

Contribution

It proposes a novel cosmological model that predicts q_0=0 without requiring exotic matter, differing from both standard and cosmological constant models.

Findings

Predicts q_0=0 without exotic matter

Offers testable differences from standard cosmology

Aligns with coasting universe models

Abstract

A new cosmological model leads to testable predictions that are different from those of both standard cosmology and models with a cosmological constant. The prediction that q_0=0 is the same as in other ``coasting universe'' models, but arises without the need for any exotic form of matter or other ad hoc assumptions.
