Whither Dark Matter

In a chapter to be published in the Annual Reviews of Astronomy and Astrophysics, available online now here, Jonathan Feng of the Universit of California, Irvine, provides the reader a readable summary of the latest discoveries associated with the search for the nature of dark matter. As the author notes, “the identity of dark matter is a question of central importance in both astrophysics
and particle physics.” While the author presents a picture of the standard model of the atom, he also addresses the very nature of the dark matter in the universe which dominates the universe itself. He addresses many possibilities but concludes that “upcoming experiments will discover or exclude many of these candidates, and progress may open up an era of unprecedented synergy between studies of the largest and smallest observable length scales.”
