ABSTRACT: In this paper, we suggest that a toy model of our universe is based on FRW bulk viscous cosmology in presence of modified Chaplygin
gas. We obtain modified Friedman equations due to bulk viscosity and Chaplygin
gas and calculate time-dependent energy density for the special case of flat
space.
