This is only partially related to the original question, but it struck me from reading this thread.

Can photons be said to experience time at all? Or is the duration of time in the photon's frame of reference between emission and absorption the same regardless of whether it was emitted from a quasar 10 billion light years away and hits our retina compared to if it is emitted from our LCD tv 5 feet away and hits our retina?
