  Based on first principles solutions in a unified framework of quantum
mechanics and electromagnetism we predict the presence of a universal
attractive depolarisation radiation (DR) Lorentz force ($F$) between quantum
entities, each being either an IED matter particle or light quantum, in a
vacuuonic dielectric vacuum. Given two quantum entities $i=1,2$ of either kind,
of characteristic frequencies $\nu_i^0$, masses $m_i^0=h\nu_i^0 / c^2$ and
separated at a distance r^0, the solution is $F=- G m_1^0 m_2^0/ (r^0)^2$,
where $G= \chi_0^2 e^4/12 \pi^2 \epsilon_0^2 \rho_\lambda$, $\chi_0$ is the
susceptibility and $\rho_\lambda$ is the reduced linear mass density of the
dielectric vacuum. This force $F$ is accurate at the weak $F$ limit and
resembles in all respects Newton's gravity; hence $G$ is the gravitational
constant. The DR wave fields and hence the gravity is propagated in the
dielectric vacuum at the speed of light $c$; these can not be shielded by
matter. A test particle $\mu$ of mass $m^0$ at $r^0$ apart from a large mass
$M$ is therefore gravitated by all of the building particles of M directly, by
a total gravitational potential $V = -G M m^0/ r^0$. For a finite $V$ and hence
a total Hamiltonian $H= m^0 c^2 +V$, solution for the eigenvalue equation of
$\mu$ presents a red-shift in the eigen frequency $\nu= \nu^0 (1- GM/r^0 c^2)$
and accordingly other wave variables. The quantum solutions combined with the
wave nature of the gravity further lead to dilated gravito optical distance
$r=r^0/(1- GM/r^0 c^2) $ and time $t=t^0/(1- GM/r^0 c^2) $, and modified
Newton's gravity and Einstein's mass energy relation. Applications of these
give predictions of the general relativistic effects manifested in the four
classical test experiments of Einstein's general relativity (GR), in direct
agreement with the experiments and the predictions given based on GR.
