Query: The Static Gravitational Field of a Spherically Symmetric Body   We continue here the exam \cite{LuMa} of a theory of gravity that satisfies
the Einstein Equivalence Principle (EEP) for any kind of matter/energy, except
for the gravitational energy. This is part of a research program that intends
to re-examine the standard Feynman-Deser approach of field theoretical
derivation of Einstein\rq s General Relativity. The hypothesis implicit in such
precedent derivations \cite{Feynman} \cite{Deser} concerns the universality of
gravity interaction. Although there is a strong observational basis supporting
the universality of matter to gravity interaction, there is not an equivalent
situation that supports the hypothesis that gravity interacts with gravity as
any other form of non-gravitational energy. We analyse here a kind of
gravity-gravity interaction distinct from GR but, as we shall see, that
conforms with the actual status of observation. We exhibit the gravitational
field produced by a spherically symmetric static configuration as described in
this field theory of gravity. The values that we obtain for the standard PPN
parameters ($\alpha = \beta = \gamma = 1$) coincide with those of General
Relativity. Thus, as we pointed out in a previous paper, the main different
aspect of our theory and GR concerns the velocity of the gravitational waves.
Since there is a large expectation that the detection of gravitational waves
will occur in the near future, the question of which theory describes Nature
better will probably be settled soon.
