It is possible, but not very likely, that viscosity could account for all the acceleration that has been attributed to dark energy," said Disconzi in a news bulleting by Vanderbilt University . "It is more likely that a significant fraction of the acceleration could be due to this more prosaic cause. As a result, viscosity may act as an important constraint on the properties of dark energy."

Previous equations and theories suggested that viscosity would prevent the Universe from "ripping" apart. The new formulation by Desconzi-Kephart-Shcerrer provides a plausible way for viscosity to allow structures to just pull apart after a certain threshold is reached.

"In previous models with viscosity the Big Rip was not possible," said Scherrer in the bulletin. "In this new model, viscosity actually drives the Universe toward this extreme end state."
