The de Broglie universal substratum, the Lochak monopoles and the dark
  universe
  We propose to interpret the dark universe (dark matter and dark energy) of
the current cosmological standard model as emerging together with ordinary
matter, from the quantum vacuum, which de Broglie called the "universal
substratum". It will be shown that this interpretation may lead to a reasonable
agreement between the current understanding of the quantum vacuum in quantum
field theory and current evidences for the existence of dark energy and dark
matter, and that dark matter can be interpreted as emerging from the QCD
vacuum, as a Bose-Einstein gluon condensate, with an energy density relative to
the baryonic energy density that agrees with observation.
