Goldstone Bosons as Fractional Cosmic Neutrinos
  It is suggested that Goldstone bosons may be masquerading as fractional
cosmic neutrinos, contributing about 0.39 to what is reported as the effective
number of neutrino types in the era before recombination. The broken symmetry
associated with these Goldstone bosons is further speculated to be the
conservation of the particles of dark matter.
