“His alarm clock ticked by the head of the bed. He gazed at its whitish face, the hands both drawing downward. There were no clocks, there. There were no hours. It was not the river of time flowing that moved the clock's hands forward; their mechanism moved them. Seeing them move men said, Time is passing, passing, but they were fooled by the clocks they made. It is we who pass through time, Hugh thought.”
― Ursula K. Le Guin, The Beginning Place

“People assume time is a strict progression of cause to effect, but actually, from a non-linear, non-subjective viewpoint, it's more like a big ball of wibbly wobbly timey wimey stuff”

“Rory: Amy. I'm gonna need a little help here.
Amy: Just stop it!
Rory: Just think it through, this will work. This will kill the Angels.
Amy: it will kill you too.
Rory: Will it? River said that this place would be erased from time, never existed. If this place never existed what did I fall off?
Amy: You think you'll just come back to life.
Rory: When don't I?
Amy: Rory—
Rory: Anyway, what else is there? Dying of old age downstairs, never seeing you again? Amy, please. If you love me, then trust me and push.
Amy: I can't.
Rory: You have to!
Amy: Could you? Could you if it was me? Could you do it?
Rory: To save you, I could do anything.
Amy: Prove it.
Rory: But I can't take you too.
Amy: You said we'd come back to life. Money-where-your-mouth-is time.
Rory: Amy, but—
Amy: Shut. Up. Together. Or not at all
