    What is the total energy of the universe?

    I would like a gross energy, not a net energy, as I saw somewhere that the net energy of the universe is zero.

    There is no reason to think that Gross energy is a well-defined concept. Presumably there are two different references frames describing the same universe, one with a lot of kinetic energy and gravitational potential energy, and one with less kinetic energy and gravitational potential energy. This could be done just by rescaling the coordinates.

    Indeed.

    Interesting discussion... So now I know of four laws of thermodynamics.
