  We briefly review the current status of a new quantum gravity theory called
Electro-Magnetic Quantum Gravity. EMQG is manifestly compatible with Cellular
Automata (CA) theory, and is based on a new theory of inertia proposed by R.
Haisch, A. Rueda, and H. Puthoff. Newtonian Inertia is due to the strictly
local, electrical force interactions of matter particles (consisting of real
electrically charged fermions) with the surrounding, electrically charged,
virtual fermion particles of the quantum vacuum. The force originates from each
charged fermion particle of the mass undergoing relative acceleration with the
the quantum vacuum particles. The sum of all these tiny electrical forces
originating from each electrically charged particle in the mass is the source
of the total inertial force of a mass, which is the force that opposes
accelerated motion in Newton's famous inertia law 'F = MA'. Gravity also
involves the same 'inertial' electrical force component that exists for
inertial mass described above. The Weak Equivalence Principle turns out to be a
physical phenomenon, originating from common 'lower level' quantum processes in
both gravitational and inertial mass. The magnitude of the gravitational mass
of a test mass on the earth results from the same quantity of electrical force
interactions as in inertia, but on the earth it is the virtual fermions of the
quantum vacuum that are actually accelerating downward (on a statistical
average basis) with respect to the test mass.
