I propose a reinterpretation of cosmic dark matter in which a rigid network
of cosmic strings formed at the end of inflation. The cosmic strings fulfill
three functions: At recombination they provide an accretion mechanism for
virializing baryonic and warm dark matter into disks. These cosmic strings
survive as configurations which thread spiral and elliptical galaxies leading
to the observed flatness of rotation curves and the Tully-Fisher relation. We
find a relationship between the rotational velocity of the galaxy and the
string tension and discuss the testability of this model.Comment: 5 page
