Just a coincidence?

I am sure it's happened to you, too. You're scrolling through your feed and two pictures from completely different sources seems to interact in a way that makes sense to you. 

This is a screenshot of my Google+ feed this morning. The one on the left is of a spiral galaxy far far away, and the one on the right is of dancers spiraling around a bit closer. 

Coincidence? I like to think there is more to it than that. We receive insights everyday. Some are so obvious we just fail to notice them. I noticed this one.
