The Black hole in Interstellar wasn't just good CGI. The VFX team accidentally created real science that even physicists had never seen before.
We all know how obsessed Christopher Nolan is when it comes down to accuracy in his movies. For the Black hole scene in Interstellar, he brought in Kip Thorne a world renowned physicist who would go on to win the Nobel prize in 2017.
To make the scene as realistic as possible, Thorne got to work and sent the VFX team equations about how light bends around a spinning black hole. They created a new software called DNGR to run the simulation. The process was so complex that each single IMAX frame took over 100 hours to render.
When it was complete, Thorne revealed that even he was seeing a fast spinning black hole in ultra high definition for the very first time.
The VFX team had accidentally made a major contribution to astrophysics. Their simulation revealed spacetime warping into shapes nobody had ever seen before.Their findings were so significant that they were published in two peer reviewed scientific journals. They also won the Oscar for Best visual effects that year.
