Where does the energy of gravity come from?

[QUOTE="Nugatory, post: 6852678, member: 382138"] ”Extending to infinity” is indeed problematic, but the problem is in the very common but imprecise natural language wording. There’s no infinity involved when we state it differently: if the gravitational potential is non-zero at a finite distance ##R## from the gravitating body and ##\Delta R## is some small number, then the gravitational potential will be smaller but still non-zero at the finite distance ##R+\Delta R##. Informally, there is no hard edge detectable even with arbitrarily precise instruments. [/QUOTE]
