What makes unexpected discoveries in science so exciting?

[Wakaleo]

I am far from being an expert in any field but like to keep my mind active and have a number of interests. I am here mainly to learn.
I believe the most interesting discoveries come when the seeker of answer/s (whether scientist, student, John Layman or other) says "Hmmm, that was unexpected!" rather than "I found it!"

Welcome!
I'm glad you're inquisitive. That's a good trait to have.
