Query: Mechanical analogies for gravitation   A quasielastic model of gravitation is developed. Gravitational field is
modeled by the flow of the transient point dilatation, which is supposed to be
continually emitted by a discontinuity of the turbulent fluid. Gravitational
attraction arises from the contact interaction of the dilatation centers.
Gravitational wave is viewed microscopically as the axisymmetric wave
propagating at a high speed along a vortex tube.
