Much work remains to be done by resolving General Relativity with Quantum Field Theory. Semi-classical theory is self-inconsistent because when coupled with Relativity's stress-energy tensor, it violates the Uncertainty Principle (Riggs, 1996). Interestingly however, Quantum Field Theory allows for the suppression of vacuum fluctuations, leading to sub-vacuum phenomena. This sub-vacuum phenomena can appear as negative energy density (Ford, 1996). Further research by Krasnikov into quantum inequalities supports the physical nature of negative energy (Krasnikov, 2003). Interestingly, Dan Solomon demonstrated a negative energy density for a Dirac-Maxwell field. Negative energy density can be formulated for a Dirac field interacting with an Electromagnetic field (Solomon, 1999), hinting that negative energy experimentation may be possible with more than just photon squeezing. Specifically, Solomon arranged a Dirac-Maxwell field as  \begin{equation}  \usepackage{physics}  \xi_{ave}\left( \ket{\Omega^{\prime}} \right)  \end{equation}
