Description
A black hole is a location in spacetime having gravity so extreme that no particles or even light can escape from it. Supermassive black holes are at the center of all galaxies and smaller ones occur after the explosive end of massive stars. Astronomers have imaged large black holes. The presentation reviews what is known about black holes including how they form and how they are detected.
