Einstein named the cosmological constant as a universal constant, introducing it to define the static cosmological model. Einstein has stated: “I should have initially set λ λ = 0 in Newton's sense. But the new considerations speak for a non-zero λ λ , which strives to bring about a non-zero mean density ρ ρ 0 of matter.” This theorem solves that contradiction between “non-zero λ λ ” and Newton’s law.
