Mass and energy are convertible to each other with E = mc^2. Cosmic background radiation average intensity roughly 2.725 K, and it's all over the place with very little variation. Suppose we add up all the energy in the universe, including the cosmic background radiation, the kinetic and gravitational energies of all the objects in the universe, all the electrical and heat energies, is it likely that the amount of mass and the amount of energy in the universe are equal to each other?
