Future Universe With w < -1 Without Big Smash

Abstract

It is demonstrated that if cosmic dark energy behaves like a fluid with equation of state p=wρ(pp = {\rm w} \rho (p and ρ\rho being pressure and energy density respectively) as well as generalized Chaplygin gas simultaneously, Big Rip or Big smash problem does not arise even for equation of state parameter w<1{\rm w} < -1.Unlike other phantom models, here, scale factor for the future universe is found regular for all time.
