What two properties of the universe are determined by the values of Ω _mass and Ω _Λ? A)size and temperature B)expansion rate and size C)size and age D)age and expansion rate E)age and temperature

Question

Quizplus · Accepted Answer

The values of Ωmass and ΩΛ determine the age and expansion rate of the universe. Ωmass is the density parameter for matter in the universe and sets the rate of deceleration of the expansion, while ΩΛ is the density parameter for dark energy which sets the rate of acceleration of the expansion. The age of the universe is determined by the expansion rate, and so both of these properties are affected by the values of Ωmass and ΩΛ.
