Visco-elastic cosmology for a sparkling universe?

Abstract
We show the analogy between a generalization of the Rayleigh–Plesset equation of bubble dynamics including surface tension, elasticity and viscosity effects with a reformulation of the Friedmann–Lemaître set of equations describing the expansion of space in cosmology assuming a homogeneous and isotropic universe. By comparing both fluid and cosmic equations, we propose a bold generalization of the newly-derived cosmic equation mapping three continuum mechanics contributions. Conversely, the addition of a cosmological constant-like term in the fluid equation would lead also to a new phenomenology.
