So I wake up this morning and find this on my floor, peeking out from a door cracked open. Now I’m not scientist but I’m not unfamiliar with the simple workings of physics. I can’t quite pin down what is going on here. I’m familiar with how light can bend around things and I considered the possibility what I could be seeing here is just light reflecting off the white walls of the room inside. Both possibilities just didn’t feel completely right. Ahh how simple things in life can be so confounding… I'd appreciate it if someone can help me understand what I'm seeing here.
