Dark Matter Day: The Lighter Side of Dark Matter

Yesterday was Halloween, but did you know it was also Dark Matter Day? Since Oct. 31, 2017 Dark Matter Day has been a globally recognized celebration of the hunt for mysterious dark matter, which makes up about 85 percent of the total mass of the universe. In this video from a Q&A livestreamed yesterday, Berkeley Lab’s Dan McKinsey, Simone Pagan-Griso, and Matt Pyle of the Physics Division share their expertise and insights about dark matter and the experiments designed to search for it.
