One of the most spectacular predictions of Einstein's theory of general relativity is that black holes may form from the gravitational collapse of a star. Using ideas in differential geometry, Penrose proved in his Nobel prize-winning theorem that black hole formation is in fact a stable prediction of general relativity. In this talk, I will discuss the many insights of Penrose that led us to what he called the "establishment viewpoint" on gravitational collapse, and where we go from here.
