Supermassive black holes: most powerful objects in the universe | Martin Gaskell | TEDxMeritAcademy

Have you ever wondered whether black holes exist? And if so, how do astronomers study them? What would it be like to be close to a black hole? UCSC astrophysicist Dr. Martin Gaskell has spent his career studying what happens around supermassive black holes in the centers of distant galaxies. He explains in simple, everyday language recent progress in understanding what is going on around these extraordinary objects as they eat up matter around them. Martin Gaskell is a researcher in the Department of Astronomy and Astrophysics at UCSC. He has over four decades of experience working on issues related to supermassive black holes (including a Ph.D.), a couple of hundred publications, and many research grants. He was a finalist for five years in a row for top teaching award at the University of Nebraska. Martin also engages in many popular talks to the public.
