The wonderful contribution Nolans did to Science! They talk about Black Holes, worm holes, higher dimensions, space- time dilation, Zero-gravity and centripetal/centrifugal force and more. Better to brush up high school physics before. Its a wonderful visualization of things considered to be "edge of science". The effort to visualize complicated things are the one to watch out for.This has paid off in some cases that they have gone scientifically so accurate to have considered to make scientific papers out of the equations and visuals.
Of course, trying to compress such huge amount of concepts in 3 hours and convey it in a simplified format, so even non-science people could have a sneak-peek and get inspired, is highly appreciable. Such compression also demands some cinematic liberties, which can be ignored, or rather necessary for commercialization. Else, this could easily become a documentary and return of investment would be improbable. Still it is touted to be the one of those movies ever to be closer to real science
Science and logic, can take you only to a certain point and what lies after that is mystery. Watch out for Nolan's clever imagination and fantasy to have a guess over the mysteries. That part is fiction, but nice to imagine
Enjoy the movie! - Interstellar _/\_ Nolans, Kip Thorne and Team
