2020 Nobel Prize in physics for work on black holes awarded to 3 scientists: Sir Roger Penrose, Reinhard Genzel and Andrea Ghez
Robert Penrose is a theoretical physicist who works on black holes. Sir Roger Penrose won half the prize for his seminal work in 1965 which proved, using a series of mathematical arguments, that under very general conditions, collapsing matter would trigger the formation of a black hole. The remaining half of the prize was shared between astronomers Reinhard Genzel and Andrea Ghez, who each lead a team that discovered the presence of a supermassive black hole, 4 million times more massive than the Sun, at the center of our Milky Way galaxy.
