So we all know that it takes work to build up a sphere of charge by taking charge from infinity and piling it up into a sphere. Since the sphere wants to break apart under repulsion, its like a spring. It has intrinsic potential energy. However it doesn't seem the case with a sphere of mass, with no charge. It takes energy to disassemble it. But no energy to build it, since it happens naturally under gravity. What does this all mean? Does this mean that in the classical sense, constructs of mass has no energy?
