  The ubiquitous ether coming from the ancient times up to middle of the twenty
century is replaced by a superfluid quantum space. It represents by itself a
Bose-Einstein condensate consisting of enormous amount of virtual
particle-antiparticle pairs emerging and disappearing in an infinitely ongoing
dance. Flowing of this medium in the non-relativistic limit is described by the
modified Navier-Stokes equation along with the continuity equation. The first
equation admits the splitting on to two coupled equations. They are the quantum
Hamilton-Jacobi equation and the equation for vorticity. The quantum
Hamilton-Jacoby equation paired with the continuity equation can be reduced to
the \Schrodinger equation. These two equations representing the kernel of the
Bohmian mechanics give finding bundle of the Bohmian trajectories. Whereas the
vorticity equation gives solutions for vortices moving along such trajectories.
As the result we come to the de Broglie's interpretation of quantum mechanics
according to which there is a pilot-wave guiding the particle (in our case it
is a vortex clot) from a source up to its detection along an optimal path that
is the Bohmian trajectory.
