  We provide a quantum field theoretic derivation of Einstein's Weak
Equivalence Principle of general relativity using a new quantum gravity theory
proposed by the authors called Electro-Magnetic Quantum Gravity or EMQG (ref.
1). EMQG is based on a new theory of inertia (ref. 5) proposed by R. Haisch, A.
Rueda, and H. Puthoff (which we modified and called Quantum Inertia). Quantum
Inertia states that classical Newtonian Inertia is a property of matter due to
the strictly local electrical force interactions of each of the (electrically
charged) elementary particles of the mass (masseon particles) with the
surrounding (electrically charged) virtual particles (virtual masseons) of the
quantum vacuum. The sum of all the tiny electrical forces (photon exchanges
with the vacuum particles) that originate in each charged elementary particle
of the accelerated mass is the source of the total inertial force of a mass
which opposes accelerated motion in Newton's law 'F = MA'. We invoked
Einstein's principle of equivalence of inertial and gravitational mass to
understand the origin of gravitational mass from the perspective of quantum
inertia. We found that gravity also involves the same 'inertial' electrical
force component that exists in inertial mass. We propose that Einstein's
general relativistic Weak Equivalence Principle originates from common 'lower
level' quantum vacuum processes occurring in both gravitational mass and
inertial mass in accordance with the principles of quantum field theory.
