Abstract
With the aid of General Relativity it has become possible, in the last twenty years, to go back in the history of the universe to its very infancy, and approach, but not solve, the enigma of its origin. Our investigation, however, brings to light new mysteries, such as that of the “missing mass”. The current competition among different alternative models and theories is a clear sign that much further progress is needed.

The free-streaming length is the average distance a particle can travel without interacting with matter scattered along the way. The weaker the coupling with ordinary matter, the longer the free-streaming length.
