How an astrophysicist uses Codex to help simulate black holes
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. The theory is currently our best explanation of gravity: instead of a force pulling objects together, gravity is the result of mass and energy bending the fabric of space and time.Chan is part of the international Event Horizon Telescope (EHT) collaboration, which published the first image of a black hole in 2019.
