How an astrophysicist uses Codex to help simulate black holes

June 11, 2026Applied AIHow an astrophysicist uses Codex to help simulate black holesCodex helps Chi-kwan Chan to refine and test algorithms that simulate the movement of electrons and ions around a black hole.Loading…ShareThe gravity around a black hole is so extreme that nothing, not even light, can escape once it gets close enough. Astrophysicists like Chi-kwan Chan study black holes with computer simulations and observations. But current algorithms and computing power limit how realistic those simulations can be.With Codex, Chan—a researcher at the University of Arizona and Steward Observatory—is tackling this problem.Black holes are among the best places to test Einstein’s general theory of relativity, he said.
