Gravity is a form of energy since it is capable of doing work (moving objects over a distance). How much gravitational energy exists in the known universe?
Is the total gravitational energy simply a function of the total mass of the universe, or does it depend on the distance between planets?
How does gravitational energy compare to the quantity of other forms of energy (EM radiation, heat, any others?) in the known universe?
