“The universe is a big place, perhaps the biggest.”

“The universe is a pretty big place. If it's just us, seems like an awful waste of space.”

“The universe is a big place. If I was lost up there, how would you ever find me”

“Don't play games with me! You just killed someone I like, that is not a safe place to stand! I'm the Doctor, and you're in the biggest library in the Universe. Look me up.”

“. . . but the Universe is an awfully big place. There is room enough for an awful lot of people to be right about things and still not agree.”

“I look up at the night sky, and I know that, yes, we are part of this Universe, we are in this Universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up—many people feel small, because they’re small and the Universe is big, but I feel big, because my atoms came from those stars.”
