Who do you think you are? Mr. Wizard? The cosmological constant proposed by Einstein is a modification of his original theory of general relativity to achieve a stationary universe (which was wrong). The lambda-cdm cosmological model introduces the cosmological constant lambda: Λ to explain cosmic acceleration, discovered in the late 1990's.The two cosmological constants are totally different concepts; one was used to keep the universe stationary; the other is to explain why the the universe expansion continues to accelerate.Don't waste your patience with me!
