  We provide a derivation of the Einstein Weak Equivalence Principle (WEP)
based on our Quantum Field Theory (QFT) of the masseon and graviton particles
called ElectroMagnetic Quantum Gravity (EMQG, ref. 1). EMQG provides a
framework for understanding Newtonian Inertia as a pure QFT process involving
the photon as the vector boson exchange particle. Photons are exchanged between
the electrically charged masseon particles (which are the ultimate consistuents
of the fermion particles of ordinary matter, and contain electrical charge and
mass-charge) of an accelerated mass, and the electrically charged virtual
masseon particles of the quantum vacuum. The sum of all the tiny
electromagnetic forces contributed by each masseon particle of the mass from
the surrounding quantum vacuum is the source of the total inertial force of an
accelerated mass in Newton's F=MA. We found that gravity involves this same
process, where now the virtual masseons of the quantum vacuum are accelerated
by the graviton exchanges between the masseons in the earth (which have mass
charge) and the virtual masseons of the quantum vacuum (which also have mass
charge). Equivalence occurs because of the reversal of the roles of the quantum
vacuum and masseons in accelerated frames and under gravity. Equivalence is not
perfect. There is a tiny imbalance between gavitational mass and inertial mass
(in favor of gravity) caused by the direct graviton exchanges with the mass
(not present in inertial mass).
