Dissipative Future Universe without Big Rip

preprint2011arXivOpen access

Abstract

The present study deals with dissipative future universe without big rip in context of Eckart formalism. The generalized chaplygin gas, characterized by equation of state p=−Aρ1αp=-\frac{A}{ρ^\frac{1}α}, has been considered as a model for dark energy due to its dark-energy-like evolution at late time. It is demonstrated that, if the cosmic dark energy behaves like a fluid with equation of state p=ωρp=ωρ; ω<−1ω< -1, as well as chaplygin gas simultaneously then the big rip problem does not arises and the scale factor is found to be regular for all time.
