In its gravitational form, it can be re-written as the Poisson equation by replacing the gravitational field with the gravitational potential.
Rossi and Testa noticed an inconsistency between it and the canonical commutation relations, and a pure-glue form of it was implemented to apply to both gluons and quarks by Chen and Belloni. In theories of quantum gravity, this law implies that the total energy-momentum density at every point in space vanishes, and it is non-linear in QCD, while in QED it can be implemented by choosing wave functions that are dependent only on the transverse parts of the vector potential. In its gravitational form, it can be re-written as the Poisson equation by replacing the gravitational field with the gravitational potential. It can be used to demonstrate the safety of a Faraday cage, and in the case of stationary charges it is equivalent to Coulomb's law. The first of Maxwell's equations, for 10 points, name this physical law that states the total electric flux out of a closed surface is equal to the charge divided by the permittivity.
