Dark matter is one of the grandest unsolved mysteries in physics. What is it? What is it made of? How does it interact with “normal” matter? At the Oct. 15, 2020, Midday Science Café, viewers learned about two projects that explore the nature of dark matter, one of the most pressing questions in contemporary physics. Vetri Velan discussed how experimental particle physicists are trying to search for dark matter here on Earth. Or, more precisely, under the Earth. Sinéad Griffin discussed how scientists are taking a new approach to searching for dark matter by designing materials specifically suited to detect dark matter.
