Sometimes, at night, we venture outside and look up at the sky. And ponder.

What's behind at all?

An old man with a beard? Unlikely.

An old woman with a beard? Unlikely and scary.

But then what?

The Big Bang is a nice enough idea, but what came before the Big Bang? A Bigger Bang? And before that? A Biggest Bang? And before that?

At that point, we sigh, tell ourselves that smarter men have failed to figure this out, and go back inside to our loving family.

After all, there are more important things to worry about.

Like what's for dinner tomorrow night.
