A proof? Verifiable data? Um...okay.
Well, how big is the universe?
I'm sorry, just give me a moment.
How do you know?
I know because all the data indicate it.
But it hasn't proven yet?
No.
You haven't seen it.
How do you know for sure?
I don't, I just believe it.
Mmm.
It's the same with love, I guess.
