First off, E = mc<sup>2</sup> describing a relationship between energy and matter is only one corollary. It is also part of a well known problem in chemistry... Or is isotopic mass not less than the sum of it's parts? The equation itself HAS been derived from the Theory of Relativity, and is a direct consequence of the energy momentum four vector for an object with 0-momentum. The quote you provide from the paper states that the theory is not enough for a rigorous PROOF, but it never tries to deny the derivability of the equation. Derivation and proof are two entirely different things. | First off, E = mc<sup>2</sup> describing a relationship between energy and matter is only one corollary.
