That is a cool thought. It is also cool that each arc photon that my system detected, popped into being in a star that was over half way across the universe and it happened 8 billion years ago - and then each photon travelled all that way to get here, passing galaxies, stars and dust clouds. While the photons were on their journeys, the sun and earth formed, life started up and humans evolved - eventually one of those humans had a telescope pointed in just the right direction at just the right time and a few of those tiny photons passed down the 10 inch aperture of my scope and then finally gave up their energy and information in my tiny CCD.
