Time in the "eye" of a photon
Dumb question...but thought I'd throw it out there.
So, ever since I was a little kid of 6 or so, I loved to look up at the sky. I knew all those stars were just suns. I also knew I was looking back in time, many thousands to millions of years, since all the light from those stars would have taken that long to reach me. For all I knew, everything I see doesn't even exist anymore...but I'd never know it.
Okay...to my question, since time, at the speed of light, moves very very very slowly (or not at all?) relative to the observer...IF you were a photon, how long would it seem to you that your journey from a sun, 1 million light years from Earth, took?
