It is assumed that dark energy (69.1% of what constitutes our Universe) is quantized and behaves as a superfluid. We hypothesize that the flux described in Gauss's law for gravity is real and corresponds to dark energy absorption into massive particles, driven by spin. A quantum potential consequently arises from the pressure gradient around massive bodies, allowing us to obtain a formula for quantum gravity without resorting to gravitons. The Newtonian gravitational constant disappears and Einstein field equations, along with their metrics, are presented in a modified form, highlighting the role of dark energy's fluid dynamics, indicated as the quantum cause of the relativistic effects predicted in special and general relativity. We also analyze the consequences of light propagation through dark energy, we explain gravitational waves as negative pressure waves propagating through dark energy and Lorentz factor as the rheogram of dark energy. Considering the unifying and clarifying faculty of an approach to relativity and cosmology based on the hydrodynamics of superfluid dark energy, it seems appropriate to continue with further investigations. Experimental verifications are eventually suggested.
