The 2020 Nobel Prize in physics was announced: half of the prize was awarded to Roger Penrose for “discovering that general relativity predicted the formation of black holes”; the other half was awarded to Reinhard Genzel and Andrea Ghez for “discovering super dense objects in the center of the galaxy”. < p > < p > Roger Penrose invented a clever mathematical method to explore Einstein’s general theory of relativity. His research reveals how general relativity predicts the formation of black holes. Roger Penrose was born in Colchester, England in 1931. He graduated from Cambridge University in 1957. He is a professor at Oxford University. Reinhard Genzel was born in 1952 in barthenburg, Germany. He received his doctorate from the University of Bonn in 1978. He is the director of Max Planck Institute of extraterrestrial physics in Germany and professor of University of California, Berkeley. Andrea Ghez was born in 1965 in New York.
