Oppenheimer: Remembering the physics that first made him great
The HinduThere is a scene in Christopher Nolan’s new film, Oppenheimer, where the eponymous physicist is thronged by his adoring pupils after his paper is published. They have gathered to celebrate the ‘black hole paper’ that J. Robert Oppenheimer wrote with his student Hartland Snyder. The work of Oppenheimer and Hartland Snyder helped transform black holes from figments of mathematics to real, physical possibilities – something to be found in the cosmos out there. Oppenheimer and Snyder had to work out how the contraction of the star would affect the spacetime inside it.. For all their simplifications, their final result provided a remarkably accurate picture of the birth of a black hole. Unfortunately, most physicists were not ready to accept the weirdness of black holes yet and argued that the idealisations that Oppenheimer and Snyder had made were too unrealistic.
