I noticed an odd behavior in a mirror that still has me puzzled to this day. There is an undiscovered science there for anyone that can figure it out.
So here is the observation: I was in bed one night looking at the ceiling. I could see the reflection of light on the ceiling coming from my computer on the desk. I have a large mirror type closet sliding door. In the mirror I noticed the light reflection on the ceiling was in a different spot in the mirror. It reminded me of "Through the Looking Glass" since the reflected image was different in the mirror. Quite possibly an extra-dimensional property of light our scientists are not yet aware of.
