Here’s a thought to ponder the next time you go stargazing: Scientists now believe that instead of an estimated 100 billion galaxies in the universe, there are one TRILLION! (Whoops, we were just off by a modest factor of 10!)
To me this is a wonderful metaphor for our ignorance. No matter how smart we are (or think we are), there will always be more that we simply don’t know.

P.S. Here’s another question to ponder: If there are so many stars in the universe, why is the sky still dark at night?
