>That was a pretty boring response. Do better. ;)

You'd make a good physics teacher for young teenagers... I can totally see your wide-eyed enthusiasm getting young people hyped to the point where they want to go further with the subject.

Your assumption is obviously only correct for photons that aren't absorbed by walls (i.e. anything you did inside a building isn't 'recorded'), clouds (anything you did on a cloudy day...), the Earth's atmosphere which bounces a fair bit back down, any other object between you and the observer which could absorb the photons or add so many more that your image is inseparable from the rest of the light from the Sun or another star along the way and, of course, Red Shift, which would mean that after a couple of billion light years your light wouldn't be visible light anymore, just infra-red and microwaves.

Totally mind blowing until you actually consult your mind.
