We wish to understand why the night sky is dark and the nature of the dark matter in the universe; these topics are intimately related. The darkness of the night sky is due to the age of the universe, its rate of expansion and its content of luminous matter in the form of stars and galaxies. However, the latter have motions, which imply the existence of large amounts of non-luminous material, probably in the form of particles. These slowly decay, producing photons. So while intergalactic space is dark, it is not completely black. Understanding the relation between the dark sky and dark matter is comparable to a modern vision of Olber's paradox.The approach of the authors is to compare the best observational data from large telescopes with the best cosmological theroy based on general relativity and particle physics. This attempts to give us a more accurate picture of the universe and the exotic material believed to constitute dark matter.
