How do you know?

- How big is the universe? 

- Infinite. 

- How do you know? - I know because all the data indicates it's infinite. - But it hasn't been proven yet. 

- No. - You haven't seen it. - No. - How do you know for sure? - I don't, I just believe it. 

- It's the same with love I guess.
