### Local Pressure of the Gravity Field & Vacuum

#### Abstract

The existence of negative pressure of vacuum follows from the cosmological models, based on the results of observations. But, is it possible to detect the pressure of the vacuum as per the geometry of the space around the local gravity system? The gravitational defect of mass is interpreted as the transfer of energy to the vacuum, which becomes apparent from its deformation. We determine the gravitational impact of matter on the vacuum and opposite in the sign pressure of it in case of weakly gravitating static centrally symmetric distribution of matter. We have evaluated a possibility to extend the obtained results to arbitrary gravitational systems. The equation of state gives the deceleration parameter of the universe consistent with its accelerating expansion.
