Theory of unification

The Theory of unification is a unified theory of everything; one that unifies gravity to the strong and weak nuclear forces, and electro magnetism. One such theory is string theory.

When Rodney Mckay thought he was about to die after becoming infected with alien nanites in an Ancient viral lab in Atlantis, he said to tell everyone that he was close to having a theory of unification, but the papers were lost when he was saving children.

When Rodney Mckay was implementing a hyperdrive generator on a gateship, he said "This makes non-linear dynamics look like string theory" (which is one theory of unification).
