Main Question or Discussion Point
Thermodynamics asserts that energy can neither be created nor destroyed and thus the total energy of the universe is always constant. Thus the accelerating expansion of the universe indicates that some form of energy is being converted into another form at increasing rate? Can this be explained in simple terms? On the other hand, if the total energy of the universe was not constant but was instead tied to, say, the state of evolution of the universe, would this neccessarily violate the first law of thermodynamics?
