A mathematical method for obtaining the parameters of the Universe is found. New cosmological equations linking the parameters of the Universe with the fine structure constant "alpha" are derived. The appearance of the constant "alpha" in cosmological equations opens new possibilities in cosmology. In this paper, we investigate the phenomenon of the appearance of the microcosm constant "alpha" in cosmological equations. Cosmological equations are combined into systems of cosmological equations. This makes it possible to obtain the parameters of the universe as the solution of the system of algebraic equations of the universe. The theory based on the law of scaling of large numbers allows us to obtain the parameters of the observed Universe with an accuracy close to the accuracy of the Newtonian constant of gravitation G. It is shown that all the main parameters of the Universe and large numbers of scales 10^20 - 10^180 are composite quantities and include the fine structure constant "alpha". The fine structure constant "alpha" shows itself not only as a fundamental constant of the microworld, but also as the main constant of cosmology. The "alpha" constant makes it possible to obtain the values of the parameters of the Universe by a mathematical method from the electron constants. The fundamental connection between the parameters of the Universe and electron constants is revealed.
