Despite its critical role in forming galaxies, the nature of dark matter remains mysterious. This talk will introduce the theories that have been proposed to explain dark matter and will explore how scientists search for a substance that is virtually undetectable.

About Alex Moskowitz:

Alex Moskowitz recently earned his PhD in Astrophysics from Carnegie Mellon University. His research focuses on the tiny dwarf spheroidal galaxies that orbit the Milky Way, which he uses to test theories of dark matter and gravity. Alex has shared his expertise and enthusiasm for the cosmos for many years at the Science Center’s “Skywatch” public observing nights, first as a volunteer, and now as an official Buhl planetarium presenter. In his free time, Alex enjoys playing the cello and participating in improv comedy at the Steel City Improv Theater.
