Some mirrors reverse left and right, others close and far. Some mirrors, crafted especially for NASA, reverse top and bottom.
Not mine. It reverses past and future. I smile then frown while the mirror me frowns then smiles. I bounce a ball off the mirror and in the image, the ball bounces before being released from my hand.
It's just an optical illusion, of course. The mirror can't see into the future or anything mystical like that. It just reflects a distorted image, and the easiest way for your mind to interpret the image is to imagine that cause and effect have been reversed.
But it still gets me to thinking every once in a while. Like the other day, when I was using two normal mirrors to comb the back of my head, I wondered what would happen if I had two of my time reversing mirrors. If I could just position them to reflect off each other, I could use them to see into the future!
Then I realized that in order to position them correctly, you would have to put one of them ten seconds into the past, which just goes to show you how easy it is to get confused thinking about mirrors.
[In the mirror image, I wrote this posting before logging on before coming to the realization about not being able to see into the future before combing my hair before bouncing the ball before frowning before smiling before I got the mirror.]
