- Question about its formulation
Given that the Minkowski metric implies the Lorentz transformations and special relativity, why do the equations of relativistic quantum mechanics, i.e., the Dirac and Klein-Gordon equations, require a mass term to unite quantum mechanics and special relativity? Shouldn't their formulation in Minkowski 4-space be sufficient for the unification of QM and SR? Furthermore, why wouldn't formulating the Schrodinger equation in Minkowski 4-space also make that equation relativistic?
