✦ Synopsis


Cosmic strings are linear topological defects which are predicted in many "grand unified" models of particle physics, and which are used to construct a promising theory of large-scale structure formation. Cosmic strings share many features with vortices in helium 3. Similarities and differences are reviewed in this paper. A couple of experiments with helium 3 vortices which would yield important information for cosmology are suggested.
