They do it with mirrors (Posted on 2006-04-26) Difficulty: 3 of 5
If I stand in front of a mirror, the light takes a finite, albeit small, amount of time to reach my eye.

So I am seeing myself as I looked some small fraction of time in the past.

Now if I stand with a second mirror behind me, I can see an infinite number of images of myself, each slightly older.

If I had my arm raised, and then I lowered it, can I still see an image of myself with raised arm?
