*> you've asserted that the total gravitational energy is identically zero,* NO! Two particles have zero gravitational potential energy only if they are infinitely far apart, at any other finite distance it's negative. What I've asserted is that if General Relativity is correct then the negative gravitational potential energy plus the positive mass/energy that comes from rest mass, photons, neutrinos, kinetic motion, and all other well-known sources of energy must sum to zero. But when we actually observe the universe that doesn't seem to work because the negative gravitational energy produced by all the stuff we can see only amounts to about 30% of what would be needed to balance out the positive energy that comes from matter even if you include Dark Matter. However we've also noticed Dark Energy that causes the universe to accelerate. Accelerating the entire universe to the degree we've seen would require a very large additional negative potential energy reservoir of some sort, like the vacuum energy that is part of space itself, and it turns out that the amount needed would provide the missing 70% to make the total energy of the universe be exactly zero.
