May 22, 2021, Dr. Janna Levin (Columbia University's Barnard College)
Dr. Levin helps us to understand, and to find delight in, black holes – perhaps the most opaque theoretical construct ever imagined by physicists. She takes us on an exploratory tour of the neighborhood of a black hole, and help us feel the visceral experience of encountering black holes of different masses. The title of the talk is also the title of her recently published popular-level book. (Originally scheduled for April, this talk had technical problems, and was re-recorded successfully in May.)
