Gargantua, the black hole from Interstellar, was not simply imagined. Its appearance was calculated using Einstein’s general theory of relativity, with light paths traced through curved spacetime and rendered on an IBM supercomputer. Every distortion, every arc of light, and the glowing ring around the event horizon followed real physics. The result was so accurate that it led to new scientific insights, later published in peer-reviewed papers — blurring the line between cinema and astrophysics.
