I get that, TARS. But we've got to figure something out or the people on Earth are gonna die. Think! Cooper... they didn't bring us here to change the past. Say that again. They didn't bring us here to change the past. No, they didn't bring us here at all. We brought ourselves. TARS, give me the coordinates for NASA in binary. In binary. Roger. Feeding data. "It's not a ghost." "it's gravity." Don't you get it yet, TARS? I brought myself here! We're here to communicate with the three-dimensional world. We're the bridge! I thought they chose me. - But they didn't choose me, they chose her. For what, Cooper? To save the world. All of this is one little girl's bedroom. Every moment. It's infinitely complex. They have access to infinite time and space, but they're not bound by anything! They can't find a specific place in time. They can't communicate. That's why I'm here. I'm gonna find a way to tell Murph... just like I found this moment. - How, Cooper? - Love, TARS, love. It's just like Brand said. My connection with Murph, it is quantifiable. it's the key! What are we here to do? Find how to tell her. The watch. The watch. That's it. We code the data into the movement of the second hand. TARS, translate the data into Morse and feed it to me. Translating data to Morse. Cooper, what if she never came back for it? She will. She will. Murph, I can see his car! He's coming, Murph! Okay. I'm coming down. How do you know? Because I gave it to her.
