On the Theory of Everything (or TOE)
When all is said and done, the mathematical equation for the most sought-after Theory of Everything will be E=mc2 without the subjectivity associated with c2 as in E=m where mass (m) is merely the manifestation of energy (E). This also means that the ultimate mathematical symbol is E without even a need for that m for mass since classical physics follow quantum mandates dictated by the energy fields.
