  A new approach to solving two of the cosmological problems (CCPs) is proposed
by introducing the Abbott-Deser (AD) method for defining Killing charges in
asymptotic de Sitter space as the only consistent means for defining the
ground-state vacuum for the CCP. That granted, Einstein gravity will also need
to be modified at short-distance nuclear scales, using instead a nonminimally
coupled scalar-tensor theory of gravitation that provides for the existence of
QCD's two-phase vacuum having two different zero-point energy states as a
function of temperature. Einstein gravity alone cannot accomplish this. The
scalar field will be taken from bag theory in hadron physics, and the origin of
the bag constant B is accounted for by gravity's cosmological constant - noting
that the Higgs mechanism does not account for either the curved-space origin of
lambda or the mass of composite hadrons. A small Hubble-scale graviton mass
naturally appears external to the hadron bag, induced by lambda. This mass is
unobservable and gravitationally gauge-dependent. It is shown to be related to
the cosmological event horizon in asmyptotic de Sitter space.
