A Different Approach to $f(R)$-Cosmology

TL;DR

This paper presents a novel $f(R)$-cosmology model that explains various cosmic epochs, predicts future collapse, and suggests possible avoidance of collapse and universe revival, offering a new perspective on cosmic evolution.

Contribution

It introduces a different approach to $f(R)$-cosmology that unifies multiple cosmic phases and predicts future collapse with potential mechanisms for avoidance and revival.

Findings

Explains early inflation and cosmic background radiation emergence.

Predicts future collapse of the universe.

Suggests mechanisms for avoiding collapse and universe revival.

Abstract

Here $f(R)$-cosmology is discussed using a different approach. This model explains early-inflation, emergence of cosmic background radiation at the exit from inflation, cosmic deceleration during radiation-dominance followed by deceleration due to curvature-induced matter and acceleration in the very late universe due to curvature-induced phantom dark energy. This model predicts collapse in the future universe. Further, a possible avoidence of collapse as well as revival of very early universe is suggested.
