Three scientists who unravelled some of the deep mysteries of black holes, the awe-inspiring pockets of the universe where space and time cease to exist, have won the 2020 Nobel Prize in Physics.
Britain's Roger Penrose, professor at the University of Oxford, won half the prize of 10 million Swedish crowns (£867,411) for his proof that black holes are a direct consequence of Albert Einstein's general theory of relativity.
German Reinhard Genzel, of the Max Planck Institute and University of California, Berkeley, and Andrea Ghez, at the University of California, Los Angeles, shared the other half for discovering that an invisible and extremely heavy object governs the orbits of stars at the centre of our galaxy.
