Let me put it like this, in future there might be better movies on astro physics with new updated theories and multiple researches but even when humans crack the fifth dimension (could take centuries from now) they just can't give a better evaluation about this a powerful but a non observable force not the gravity but love. No matter how many laws or theorems or equations they propose, no physics can explain like Nolan made us feel. This is what separates Interstellar with other Sci-fi films.
