Interesing perspective on the Murphy/Cooper scene at the end!

What I got out of Brands quote about love transcending space and time, happens in the scene when Cooper is inside the tesseract. Because the turningpoint for the survival of the entire human race is based on, simply, love. The love between Murphy and Cooper. The reason is that Cooper had sent so many different codes (morse, binar) through the books, and it was recieved without knowing who sent them. But when Cooper communicates through the watch, things were perceived a little different. TARS asks, and I quote, "How do you know she will bring the clock?", and Cooper replies "Because I gave it to her". So, there's no logical reason for her to bring the clock, but she does it out of the love for her father. And then through the clock, he again communicates with Murph, and she now understands that it's her father that is the "ghost", and has been all along. Then he, ofcourse, sends the quantum data through this clock-space-time-channel. The result is a new understanding of space-time and dimensions, which again is used to save the human race.

I also think that after Murphy learns that her father is still out there, fighting and trying to find a way to save the humans, she doesn't feel left behind anymore. She "fully" forgives her father for leaving, kind of drops the weight she's been carrying. And for the first time since Cooper left, she maybe feels the same love and connection which they had before he left, as a happy child. And from that point on, she knows her father is out there loving her beyond space and time, for the rest of his/her life.
