Some
IMDB triviarelated to that, they had an actual physicist as executive producer and consultant on the film for all of that stuff:
Early in pre-production, Dr. Kip Thorne laid down two guidelines to strictly follow: nothing would violate established physical laws, and that all the wild speculations would spring from science and not from the creative mind of a screenwriter. Christopher Nolan accepted these terms as long as they did not get in the way of the making of the movie. That did not prevent clashes, though; at one point Thorne spent two weeks talking Nolan out of an idea about travelling faster than light.
To create the wormhole and black hole, Dr. Kip Thorne collaborated with VFX supervisor Paul J. Franklin and his team at Double Negative. Thorne provided pages of deeply sourced theoretical equations to the team, who then created new CGI software programs based on these equations to create accurate computer simulations of these phenomena. Some individual frames took up to 100 hours to render, and ultimately the whole CGI program reached to 800 terabytes of data. The resulting VFX provided Thorne with new insight into the effects of gravitational lensing and accretion disks surrounding black holes, and led to him writing two scientific papers: one for the astrophysics community and one for the computer graphics community.
According to Dr. Kip Thorne, the largest degree of creative license in the film are the clouds of the ice planet, which are structures that probably go beyond the material strength which ice would be able to support.
Kip Thorne won a scientific bet against Stephen Hawking upon the astrophysics theory that underlies Interstellar (2014). As a consequence, Hawking had to subscribe Penthouse magazine for a year. This famous bet is depicted in The Theory of Everything (2014) which was released in the same year as Interstellar.
A lot of good ones there, kinda liked this one:
The wormhole shown in this film near Saturn is exactly the same place shown in Man of Steel (2013), produced by Christopher Nolan. In Man of Steel (2013), Superman as a child arrives into our solar system in a spaceship when it drops out of warp.
Sorry if these were posted before, really only just saw it and started reading the thread.
