ABSTRACT: The particle identity of dark matter is one of the most pressing open questions in high energy physics. In this talk, we review recent theoretical and experimental progress in the search for dark matter and the existence of dark forces. We highlight a particular class of searches based on dark matter collecting in the Earth or Sun that subsequently annihilates into dark force particles that are the analog of the ordinary photon. The observation of this "dark sunshine" or "dark earthshine" would be a smoking-gun signature for dark matter that would confirm a set of theories that have become particularly interesting from a range of recent experimental hints for new physics.
