## The Dirac Equation in a Gravitational Field

**Authors:** Jack Sarfatti

Einstein's equivalence principle implies that Newton's gravity force has no local objective meaning.
It is an inertial force, i.e. a contingent artifact of the covariantly tensor accelerating
(non-zero g's) Local Non-Inertial Frame (LNIF) detector. Indeed, Newton's gravity force disappears
in a locally coincident non-accelerating (zero g) Local Inertial Frame (LIF). The presence or
absence of tensor spacetime curvature is completely irrelevant to this fact. In the case of an
extended test body, these remarks apply only to the Center of Mass (COM). Stresses across
separated parts of the test body caused by the local objective tensor curvature are a logically
independent separate issue. Garbling this distinction has generated not-even-wrong critiques of
the equivalence principle among "philosophers of physics" and even among some venerable confused
theoretical physicists. Non-standard terms coupling the spin-connection to the commutator of the
Dirac matrices and to the Lorentz group Lie algebra generators are conjectured.
