Recent observations indicate the existence of significant large-scale structure on scales >40 h0-1Mpc. That this is also the typical scale for surviving structure in the hot dark matter models for galaxy formation (for example, neutrinos with masses mν ≈ 30 eV) may not be a coincidence. If neutrinos are to be reinstated as the leading candidates for the dark matter of the universe, it becomes crucial to understand the origin of their mass in the context of the superstring. The authors examine the possibility for small but non-zero neutrino masses in a class of superstring models giving rise to acceptable low-energy phenomenology.
