In this study, a new concept is introduced into physics - gravitational cells. These cells are densely compressed elementary particles: a proton and an electron. The body of a black hole consists of a huge number of such cells.
On this theoretical basis, using the Schwarzschild radius formula and the adapted Coulomb formula, a formula for the gravitational constant was obtained and its value in the gravitational field of black holes was calculated, 𝑮𝟎=𝟔,𝟕𝟗𝟐𝟕∙𝟏𝟎−𝟏𝟏. Also, scientific substantiation of the value of the usual gravitational constant 𝑮 was obtained.
In this study, a new physical constant was determined - the mass of the gravitational cell of a black hole 𝒎𝟎=𝟏,𝟓𝟏𝟏𝟓𝟗𝟑∙ 𝟏𝟎−𝟐𝟕 kg.
Based on the results of the study, conclusions were drawn regarding the gravitational mass of the proton and the electron.
