Gravitation is not a force.  Gravitation is a distortion of
spacetime.  What "force" is necessary to bend otherwise parallel lines
into covergence on the surface of a sphere?  None at all.  Test mass
free fall follows the shape of space in a minimum action path.

Nothing is necessary to keep a hydrogen atom inflated, either.  The
Bohr orbital radius is the global energy minimum between postive
proton and a negative electron.  It requires a neutron star's worth of
squeeze to find another, shallower minimum.

If you like gravitaiton as a force, then Weitzenboeck and affine
gravitation wherein spactime torsion (not GR's spacetime curvature)
looks like a Lorentz force.  Affine gravitation exactly contains all
of metric gravitation (General Relativity) plus additional testable
predictions.  It has one fewer founding postulate, too.  Alas, it's a
bitch to calculate even compared to GR.

Now for the fun part.  Predictive models of gravitation and quantum
mechanics are absolutely incompatible.  They are either both wrong
fundamentally (e.g., epicycles vs. a heliocentric solar system) or are
both limiting cases of a more general and inclusive model.  Nobody has
any idea how to unify them.  

Gravitons are mathematically consistent curve fitting like dark matter
and dark energy.  There is no empirical evidence for their existence
as such (e.g., promoting a virtual particle into a detectable real
particle or detecting an extant real postulated particle).
