Über-Morlock: We all have our time machines, don`t we. Those that take us back are memories... And those that carry us forward, are dreams.
Hartdegen: My question is why can`t one change the past?
Vox: Because one cannot travel *into* the past.
Vox: Do you know what it`s like to remember everything?
Über-Morlock: Come a little closer, I don`t bite.
Teacher: If you do that again, I will re-sequence your DNA.
Über-Morlock: You built your time machine because of Emma`s death. If she had lived it would never have existed, so how could you use your time machine to go back and save her? You are the inescapable result of your tragedy, just as I am the inescapable result of you.
Hartdegen: This is a perversion of every natural law!
Über-Morlock: (grabs him by the throat) And what is time travel? But your pathetic attempted to try to control the world around you!
Phillby: A professor from Columbia University should not be corresponding with a crazy German book keeper.
Hartdegen: He`s a patent clerk, not a book keeper, and I think Mister Einstein needs all the support I can give him.
Über-Morlock: You think I don`t know you Alexander? I can look inside your memories, Your nightmares, your dreams. You`re a man haunted by those two most terrible words, What If?
Hartdegen: You`re forgetting one thing. What if?
Über-Morlock: Who are you, to question 800,000 years... of evolution?
Phillby: Nothing can change what happened.
Hartdegen: No, you`re wrong. Because *I* will change it.
Hartdegen: You were right, Philby. We did go too far.
Hartdegen: I could come back a thousand times... and see her die a thousand ways.
Phillby: (looking at a futuristic picture) I wonder if we`ll ever go too far.
Hartdegen: With what?
Phillby: (pointing at the picture) With this. With all of this.
Hartdegen: No such thing.
Phillby: I`m glad he`s gone. Maybe he`s finally found a place where he can be happy.
Jogger: Nice suit. Very retro.
Hartdegen: Thank you.
Jogger: Bet that makes a hell of a cappuccino. That thing.
Hartdegen: How did this happen?
Soldier #1: The moon. Come on, move it.
Hartdegen: That`s impossible. What happened?
Soldier #1: What, you been living under a rock?
Hartdegen: Yes, I`ve been living under a rock! Now tell me...
Soldier #1: The demolitions for the lunar colony screwed up the orbit, okay? The moon`s breaking up, all right? Now, come on.
Vox: (an image of Vox appears) Welcome. How may I help you?
Vox: (Alexander Hartdegen looks behind Vox) Over here.
Mara: Some things are better left unsaid.
