    • Abstract

       

      We study the relative rates of expansion in cosmologies admitting curvature dependent and energy dependent bulk viscosity. It is conjectured that curvature dependant bulk viscosity may be a phenomenological way of representing gravitational vacuum polarization around the time of the Planck era.
