General Relativity in the Radius of Particles

Through Minkowsky’s Geometry and the equation on the curva- ture of a light ray, derived from the Theory of General Relativity, we deduce that in the presence of a mass, a constant volume must always be subtracted from that volume containing that mass, by decreasing the radius of a sphere containing such a mass. So we show that the same phenomenon physic leads also to a reduction in the radius of mass of particles with mass.
