    "abstract": "Hydrodynamic derivation of the entrainment of matter induced by a surface\nelastic wave propagating along the flexible vacuum-matter interface is\nconducted by considering the nonlinear coupling between the interface and the\nrarefaction effect. The critical reflux values associated with the product of\nthe second-order (unit) body forcing and the Reynolds number (representing the\nviscous dissipations) decrease as the Knudsen number (representing the\nrarefaction measure) increases from zero to 0.1. We obtained the critical\nbounds for matter-freezed or zero-volume-flow-rate states corresponding to\nspecific Reynolds numbers (ratio of wave inertia and viscous dissipation\neffects) and wave numbers which might be linked to the evolution of the\nUniverse. Our results also show that for positive evolution of the matter (the\nmaximum speed of the matter (gas) appears at the center-line) there might be\nexistence of negative pressure.",
