  Kibble mechanism drastically underestimates the production of topological
defects, as confirmed recently in atomic and condensed matter systems. If
non-thermally produced, they can be cosmological dark matter of mass 1-10 PeV.
If thermalized, skyrmion of mass 1-10 TeV is also a viable dark matter
candidate, whose decay may explain $e^\pm$ spectra in cosmic rays recently
measured by PAMELA, FERMI, and HESS. Models that produce magnetic monopoles
below the inflation scale, such as Pati-Salam unification, are excluded.
