Now that he has read the paper, he’s glad to see they slowed it down for a reason. “When I saw the movie, I immediately saw that the black hole did not look as it should for a near maximally spinning black hole,” says Andrew Hamilton of the University of Colorado in Boulder. “The first images we gave him didn’t have the Doppler shift, and I think he fell in love with them.” Far from realism “We base it in science, but we always give control so that artists can change it,” says James. It also made one side of the disc much darker, to the point of almost being invisible. They found that the black hole’s rotation turned the glowing red matter a cool blue, thanks to the Doppler effect shortening the wavelength of the light it gave off. As the team worked on the movie, they added levels of scientific detail.

Gargantua’s disc in the movie is also redder and brighter than it would be in real life (see above). Nolan didn’t like this asymmetry and thought moviegoers wouldn’t understand why, so the team slowed it down, says James. That’s because the movie’s time dilation effects meant the black hole had to spin very fast, causing it to drag the light to one side. The result looked good, but the central black hole seemed to be squashed up against one side. “I’d ask him a question and maybe a week later, sometimes a month, I’d get a beautifully presented paper that he’d laid out with references going into the history of the problems I’d been asking about,” says Oliver James, chief scientist of Double Negative. He got together with director and co-writer Christopher Nolan, and also with London-based visual effects studio Double Negative to create the movie’s black hole, Gargantua. Interstellar’s premise was first conceived by physicist Kip Thorne of the California Institute of Technology, who wanted to make a realistic movie about black holes.
Now, a joint paper published in the journal Classical and Quantum Gravity from the movie’s visual effects team and scientific consultant reveal that the real black hole (see above) was deemed too confusing for audiences, and some of the science had to be toned down. Last year’s hit film Interstellar used real scientific equations to depict what happens when a team of space farers venture near a supermassive black hole.
