farico, you are exactly right, and that is the point. You just add mirrors to make the distance needed shorter and shorter.
I was just taking the example to a logical absurdity to reason that we could potentially make a small array of millions of mirrors, here on earth, that could see back in time in "real-time" if you pointed it at something.
But as I soon realized, this is basically a video camera =(
