"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. Now that he has read the paper, he's glad to see they slowed it down for a reason. "I had not realised just how careful the Interstellar team had been with their renderings."
Alain Riazuelo of the Paris Institute of Astrophysics says he appreciates the team's efforts, but a pure science project would have done things differently, because astronomers want to create models of what their telescopes might see from afar. "From an astrophysics perspective you would want to simulate different configurations of matter around the black hole, then try to predict what your observations would give you," he says – the team just choose a disc they thought looked nice.
Riazuelo met with Thorne a few years ago and gave him some early visualisations, so was slightly disappointed when the film wasn't totally realistic. "I understood after a few minutes why they had done this, but I would have preferred they stick a little more close to realism," he says, though it could have been much worse. "You should keep in mind there was nothing that obliged Christopher Nolan to try to stick to realistic science."
I'm a fan of Desplat's film music - particularly the pieces he wrote for Moonrise Kingdom and the closing fugue which nods to Benjamin Britten's Young Person's Gide to the Orchestra - The Heroic Weather-Conditions of the Universe, Part 7: After The Storm (track 21 on the album)
