Norman: "What, what?"
Harry: "You see, it's curious. Ted did figure it out, time travel. And when we get back we all get back, we're all going to tell everyone. How it's possible, how it's done, what the dangers are. But then why 50 years in the future when the spacecraft reaches a black hole does does the computer call it an unknown entry event? Why don't they know? If they don't knowm, it means we never told anyone. And if we never told anyone, it means we never made it back. Hence, we die down here."
