Newtonian gravity: Consider
two simple single charged matter particles 1,2 of masses M_{1}, M_{2},
and charges q_{1},q_{2}
of any signs, that are separated at a distance r in a
dielectric vacuum medium (Fig 1). Either particle, i,
is according to the IED model composed of charge q_{i}
of zero rest mass, but oscillating at characteristic frequency
_{i},
hence having a mass M_{i}=_{i}/c^{2}.
The internal total electromagnetic radiation fields
E_{1}, B_{1}
of 1, generated by its charge q_{1 }
,
induce in the vacuum dielectric depolarisation radiation (DR)
fields,
that
are propagated at time t to the location
r
of particle 2 as
E_{p1}(r,t),
B_{p1}(r,t);
E_{p1}=-E_{1},
B_{p1}=
-E_{p1}×
c/c^{2},
where
is
the susceptibility of the dielectric vacuum.

In the
DR fields
E_{p1}(r,t),
B_{p1}(r,t),
the
charge q_{2 } of particle 2 is acted on a Lorentz
magnetic force, or DR Lorentz force

See Fig 1. And conversely an attractive Lorentz magnetic force
F_{21}
is acted on q_{1} due to the radiation fields of charge
q_{2}. The mutual mean DR Lorentz force n is, for q_{1},q_{2}=±e,

where
_{
}
is the
linear mass density of the vacuum.

Remarks:

1)
F
is always attractive irrespective the signs of the charges, has
an inverse square formula, and is capable to penetrate
through matter unhinded. F resembles in all respects Newton's gravity;
hence
represents Newton's gravitational constant.

2)
E_{pi},
B_{i}
make up a gravitational wave, as a vacuuon dipole wave, in the
vacuum at the velocity of light c. and do
not interact with matter.

3) Since the electromagnetic fields
E_{i},B_{i}
are quantized, it follows that the gravitational force
F
and the gravitational fields are quantized (Pub
25).

4) The gravitational force and fields have their origins in
electromagnetism.

5) A corresponding scheme leads also to a prediction of a Doebner-Goldin form of self gravity
(See
Pub 19).

Motivated by an open remark by
Professor GtH regarding the completeness of a new gravity
theory, a (re)derivation of Newton's gravity (extended) and
general relativity (new) based on quantum electromagnetism has been obtained
recently.

Professor B Johansson
has
through the post doc funding + researches in 1995-2000
paved the way for the present unification research.
P-I Johansson has given continued funding support for the
unification research. Professor H-DD has communicated many discussions
since QTS 4 2005;
Professors NA (), IL ();Profs RL (), CB (); .
Professors B Johansson and NA were the first
professors who saw the significances of the de Broglie wave solutions for
the IED particle (2000-02) and polarizable dielectric vacuum.
