90 years ago, on August 8, the British physicist and mathematician Roger Penrose was born. In 1965, Penrose published an article in Physical Review Letters in which he mathematically proved that massive stars after death must undergo gravitational collapse - a process by which their matter is compressed to a very small volume. At the center of this object, a singularity arises - an area where the usual laws of physics do not apply.
Roger Penrose, German astrophysicist Reinhard Henzel, and American astronomer Andrea Guez became recipients of the 2020 Nobel Prize in Physics. Penrose was awarded the prize for the discovery that the formation of black holes is a reliable prediction of general relativity, and Henzel and Geuze were awarded for the discovery of a supermassive compact object in the center of the Milky Way. "The discovery of the darkest secrets of the Universe" - this is how the Secretary General of the Nobel Committee of the Karolinska Institute, Goran Hansson, described the contribution of the laureates to science.
