Conversely, it can be put like this:
“The emotion of Interstellar is three-fold: Nolan’s script, co-written with his brother as with all his best stuff, masters not only notions of black holes, wormholes, quantum data and telemetry, but it also makes a case for love as the one thing—feeling, fact, movement, message—that can mean more and do more than anyone in our current time, on our existing planet, can comprehend.”
The writer of this stirring summation, our own Ella Kemp, is paraphrasing a critical section of the film, when Nolan goes full literal on the concept of love and has Cooper and Dr Amelia Brand (Anne Hathaway) debate its very nature, quoted in part at the top of this story. It comes when the pair are trying to decide which potentially humanity-saving planet to use their dwindling fuel reserves to travel to. Brand is advocating for the planet where a man she loves might be waiting for her, instead of the planet that has ostensibly better circumstances for life.
Brand: “Love is the one thing we’re capable of perceiving that transcends dimensions of time and space. Maybe we should trust that even if we can’t understand it.”
“Love has meaning, yes,” responds Cooper, heretofore the film’s most outwardly love-centric character, exhibiting a stoic longing for his dead wife, while also abandoning his ten-year-old daughter on Earth for a space adventure (albeit one designed to save humanity) than has now inadvertently taken decades. “Social utility. Social bonding. Child rearing.” Ouch.
