The Nobel Prize in Physics was awarded jointly to Roger Penrose, Reinhard Genzel and Andrea Ghez on Tuesday for their discoveries that have bettered understanding of the universe, including work on black holes.
Mr. Penrose was awarded half of the prize “for the discovery that black hole formation is a robust prediction of the general theory of relativity,” the committee said.
The second half was split between Mr. Genzel and Ms. Ghez “for the discovery of a supermassive compact object at the center of our galaxy,” the committee said.
Who else won a Nobel Prize this year?
Harvey J. Alter, Michael Houghton and Charles M. Rice on Monday received the prize for their discovery of the hepatitis C virus. The Nobel committee said the three scientists had “made possible blood tests and new medicines that have saved millions of lives.”
