   • 2012, Steven Kenneth Kauffmann, “A Self-Gravitational Upper Bound on Localized Energy, Including that of Virtual Particles and Quantum Fields, which Yields a Passable "Dark Energy" Density Estimate”, in arXiv‎^[1]:

     The self-gravitational correction to a localized spherically symmetric static energy distribution is obtained from the negative Newtonian gravitational work done to successively assemble each spherical energy shell in the gravitational field of the already energy-corrected subsphere which that shell abuts.
