Interstellar in my opinion was a very revolutionary movie. It amalgamated both hard science and science fiction and wove them to tell a spectacular story. For example did you know that gravity influences time? that is why we say time is relative because the more gravity there is in a place the more time goes slower relative to that place. That is why all the satellites in space that we use for GPS are actually milliseconds faster because there is no gravity in space. After the information comes down our technology has to adjust for that error to give us the precise information, now in the movie Interstellar they took this to an interesting extreme. The astronauts landed on a planet with high gravity and after spending a few mins there they came back to oribt only to realize they have been gone for 23 years! wow!
