Cooper: Mankind was born on Earth. It was never meant to die here.
Cooper: We've always defined ourselves by the ability to overcome the impossible. And we count these moments. These moments when we dare to aim higher, to break barriers, to reach for the stars, to make the unknown known. We count these moments as our proudest achievements. But we lost all that. Or perhaps we've just forgotten that we are still pioneers. And we've barely begun. And that our greatest accomplishments cannot be behind us, that our destiny lies above us.
Murph: Hey Dad. You sonabitch. Never made one of these while you were still responding because I was so mad at you for leaving. And when you went quiet, it seemed like I should live with that decision, and I have. But today's my birthday. And it's a special one, because you told me... you once told me that by the time you came back we might be the same age. And today I'm the same age you were when you left.
Murph: So it'd be a real good time for you to come back.
