How The Penrose Singularity Theorem Predicts The End
Season 6
Episode 33
The 2020 Nobel prize in physics went to black holes. It was shared by the astronomers who revealed to us the Milky Way’s central black hole and by Roger Penrose, who proved that in general relativity, every black hole contains a place of infinite gravity - a singularity. But the true impact of Penrose’s singularity theorem is much deeper. it leads us to the limits of Einstein’s great theory.
