Particle dark matter in the universe: at the brink of discovery?

The nature of dark matter is one of the central problems of cosmology, particle physics, and gravity. It may be made of still unknown particles produced in the early universe. Much progress has been made in attempts to detect these particles and in the development of the required experimental techniques. Results from direct searches, the Large Hadron Collider, and the Gamma-ray Large Area Space Telescope offer promising opportunities within the next decade to find the missing dark matter.
