What the dark matter, the dominant form of matter in the Universe, consists of is one of the major fundamental open problems in physics, astrophysics and cosmology. This problem has been with us since the 1930’s and although we have made considerable progress, the nature of dark matter remains elusive. We will review what we know about dark matter, why we think of either new elementary particles with particular characteristics or primordial black holes as the potential constituents of the dark matter, and how we are trying experimentally and observationally to find out what the dark matter is made of. The extent of the worldwide effort to try to detect dark matter through interactions other than gravity in direct, indirect and collider searches is truly impressive, and has so far resulted in some hints of possible dark matter signals. We will discuss some of these hints and then future search prospects.
