Dark goo: Bulk viscosity as an alternative to dark energy
dark energy theory cosmological perturbation theory
2011/9/29
We present a simple (microscopic) model in which bulk viscosity plays a role in explaining the present acceleration of the universe. The effect of bulk viscosity on the Friedmann equations is to turn ...
