Can general relativity be reinterpreted via continuum mechanics or in particular Non-Newtonian fluid mechanics of some hypothetical continuous medium filling space-time ? That is, gravitation and gravitational waves relate to the stress, strain, compression and oscillations of this medium ? The Ricci tensor is like the Cauchy stress tensor, Ricci curvature like pressure ? Galaxies as vortices ? Maybe what we call mass, is nothing more than a manifestation of structured (self-similar) turbulence ? Ordinary gravitation is some kind of current or flow towards the direction of the mass.
