Varying Speed of Light, Modified Chaplygin Gas and Accelerating Universe
Anup Kumar Singha, Ujjal Debnath
TL;DR
This paper explores a cosmological model combining varying speed of light, modified Chaplygin gas, and a variable gravitational constant to describe the universe's evolution from radiation to phantom phases.
Contribution
It introduces a novel integrated model of VSL theory with modified Chaplygin gas and variable G, analyzing universe evolution with statefinder parameters.
Findings
Universe evolves from radiation to phantom era
Statefinder parameters effectively depict cosmic evolution
Model provides a unified framework for different cosmic phases
Abstract
In this paper, we have considered a model of modified Chaplygin gas in VSL theory with variable gravitational constant . We have shown that the evolution of the universe starts from radiation era to phantom model. The whole evolution of the universe has been shown diagramatically by using statefinder parameters.
