PHYSICS DEPARTMENT entrance as a shimmering sphere — just as it likely would look in real life, Thorne said. “Neither wormholes nor black holes have been depicted in any Hollywood movie in the way that they actually would appear,” Thorne said recently in an “Interstellar” science video produced by Wired magazine. “This is the first time the depiction began with Einstein’s general relativity equations. A gorgeous black hole Much of the action in “Interstellar” revolves around a giant black hole, which Cooper and his crewmates call “Gargantua.” Thorne said he and the visual-effects crew took a great deal of care to depict the lightgobbling monster accurately. The on-screen result is an exotic object that twists its infilling disk of dust and gas into complex shapes, with the overall effect further complicated by gravitational lensing — a real astronomical phenomenon in which a massive foreground object (such as a black hole) warps the light emitted by stars and other bodies located much farther away The collaboration between Thorne and the “Interstellar” visual-effects people was so successful that it will extend into the scientific literature, the physicist said. “We’re going to write several technical papers about this — one aimed at the astrophysics community, and then something for the computer-graphics community — saying, ‘Here are some things we’ve discovered about gravitational lensing by rapidly spinning black holes that we never knew before,’” Thorne said in the Wired video.
