How an astrophysicist uses Codex to help simulate black holes

University of Arizona astrophysicist Chi-kwan Chan uses OpenAI's Codex to write, debug, and refine the scientific code behind black hole simulations. Chan works with the Event Horizon Telescope collaboration, the international team that produced the first image of a black hole in 2019 and is now gathering data to make the first time-lapse video of a supermassive black hole. The simulations model the superheated plasma swirling near black holes and let scientists test Einstein's general theory of relativity against real telescope observations.
