  An unexpected explanation for neutrino mass, Dark Matter (DM) and Dark Energy
(DE) from genuine Quantum Chromodynamics (QCD) of the Standard Model (SM) is
proposed here, while the strong CP problem is resolved without any need to
account for fundamental axions. We suggest that the neutrino sector can be in a
double phase in the Universe: i) relativistic neutrinos, belonging to the SM;
ii) non-relativistic condensate of Majorana neutrinos. The condensate of
neutrinos can provide an attractive alternative candidate for the DM, being in
a cold coherent state. We will explain how neutrinos, combining into Cooper
pairs, can form collective low-energy degrees of freedom, hence providing a
strongly motivated candidate for the QCD (composite) axion.
