An ounce, in the US, is 1/16th of a pound. So, there is more matter in the average ounce of material on the earth than the average ounce of material on the sun. >I never did grasp those old > units. In any case, surely what you meant to say is "a kilogram of > flesh on Earth has more gravitational potential energy than a kilogram > of material in the sun". No, what I meant to say was that the total energy in an average ounce of material on the earth is greater than the total energy of an average ounce of material on the sun, because the mass of the material on the earth would be so much greater. This is true in virtually every inertial reference frame with E^2= p^2 + m^2 (using units that allow us to set c=1). It is certainly true in the inertial reference frame of the entire solar system.
