Miller: Vacate! I want off this ship.
Dr. Weir: You can't leave. She won't let you.
Miller: You just get your gear and get back on the Lewis and Clark, Doctor, or you'll find yourself walkin' home.
Dr. Weir: I am home.
Dr. Weir: What was made public about the Event Horizon - that she was a deep space research vessel, that her reactor went critical, and that the ship blew up - none of that is true. The Event Horizon is the culmination of a secret government project to create a spacecraft capable of faster-than-light flight.
Smith: Uhm, excuse me. See, you can't actually do that.
Miller: I will launch TAC missiles at the Event Horizon until I'm satisfied that she is vaporized. Fuck this shit!
Cooper: Listen up, doc. I'm your best friend. I'm the lifesaver and the heartbreaker.
Claire Wier: I have such wonderful, wonderful things to show you.
Cooper: What about you, Stark? You want something hot and black inside you?
[Stark gives him the middle finger.]
Cooper: Ooh, is that an offer?
Stark: It is not.
Cooper: How about some coffee then?
DJ: This ship has been beyond the boundaries of our universe. Who knows where it's been, what it's seen, and what's it brought back with it?
[Smitty uses a clamp to anchor Lewis and Clark to Event Horizon].
Wier: Be careful here. That is not a load bearing structure!
[The clamp crushes the antenna].
Smitty: It is now, doctor.
Miller: What are you telling me, that this ship is alive?
Lt. Starck, Executive Officer: You wanted an answer, and it's the only one I've got.
Miller: No, what I want lieutenant, is to survive the next 10 hours.
Miller: You miss me, you blow out the hull.
Dr Weir: What makes you think I'll miss?
Dr. Weir: Where we're going... we don't need eyes to see.
Dr. Weir: Our orders were specific.
Miller: Rescue the crew, salvage what's left of the ship. The crew is dead, doctor. Your ship killed them.
Dr. Weir: We came here to do a job.
Miller: WE'RE aborting, doctor.
Miller: I want you cool, I want you calm, NOW.
Dr. Weir: They're not your crew any more. They belong to the ship.
Chosen answer: The movie never explicitly says; but science is as yet unsure what happens to a given piece of matter once it crosses a black hole's event horizon, so who knows? The ship could have been thrown seven years forward in time, or far enough away that it took seven years for it to drift close to Neptune. Pick any explanation you like.
