  Starting with geometrical premises, we infer the existence of fundamental
cosmological scalar fields. We then consider physically relevant situations in
which spacetime metric is induced by one or, in general, by two scalar fields,
in accord with the Papapetrou algorithm. The first of these fields, identified
with dark energy, has exceedingly small but finite (subquantum) Hubble mass
scale (~ 10^-33 eV), and might be represented as a neutral superposition of
quasi-static electric fields. The second field is identified with dark matter
as an effectively scalar conglomerate composed of primordial neutrinos and
antineutrinos in a special tachyonic state.
