Big Bang and Expanding Universe!

Couple of months back I was watching a 70's romantic comedy by Woody Allen called "Annie Hall". The movie is really good and stands up to his reputation. It is also full of hilarious dialogues between various characters. One that stood out for me is

Doctor in Brooklyn: Why are you depressed, Alvy?
Alvy's Mom: Tell Dr. Flicker.
[Young Alvy sits, his head down - his mother answers for him]
Alvy's Mom: It's something he read.
Doctor in Brooklyn: Something he read, huh?
Alvy at 9: [his head still down] The universe is expanding.
Doctor in Brooklyn: The universe is expanding?
Alvy at 9: Well, the universe is everything, and if it's expanding, someday it will break apart and that would be the end of everything!
Alvy's Mom: What is that your business?
[she turns back to the doctor]
Alvy's Mom: He stopped doing his homework!
Alvy at 9: What's the point?
Alvy's Mom: What has the universe got to do with it? You're here in Brooklyn! Brooklyn is not expanding!
Doctor in Brooklyn: It won't be expanding for billions of years yet, Alvy. And we've gotta try to enjoy ourselves while we're here!

(Alvy at 9 means, when Alvy (the main character) was 9 years old)
