Shielding the gravitational field in space Author: Yanbikov Vildan Shavkyatovich. Volgograd.email@example.comАbstract: The study presents a model of the shielding of gravitational fields by cosmic protons. Gravity shielding is based on a principle. An elementary particle with a rest mass. In free fall. Shields all the gravitational fields in which it is located. In this paper, the intensity of the gravitational field from an infinite cosmic half-space is determined. The cross section of the proton shielding the gravitational field is determined. The radius of action of gravitational forces in space is calculated. The formula for calculating the distance to the galaxy from its "red" shift is obtained. The lifetime of a photon in space is calculated. The size of the visibility horizon of the Universe is determined.
