A little off subject, but a few years ago I went out fishing just as the sun was rising. Perfect morning, not a cloud in the sky. The moon at this stage, was still clearly visible and both the moon and the entire sun were sharing the same sky. Which is pretty cool but what to this day makes me question reality is the fact that the sun was directly behind me and the moon was directly infront of me and yet I could only see half the moon. How does that happen?
