A three-dimensional quantum vacuum condensate is introduced as a funda-mental medium from which gravity emerges in a geometro-hydrodynamic lim-it. In this approach, the curvature of space-time characteristic of general rela-tivity is obtained as a mathematical value of a more fundamental actual varia-ble energy density of quantum vacuum which has a concrete physical meaning. The fluctuations of the quantum vacuum energy density suggest an interesting solution for the dark energy problem.
