    And as they’re massless, photons do not experience time. Regardless of how far a photon travels, from its perspective, the journey takes no time.

      A photon would somehow experience the big bang, the heath death of the universe and everything in-between all at the same time.

      It also does not experience space, as the entire universe has been length contracted in its direction of motion into a 2d plane. It is simultaneously occupying every point along its path. So it doesn’t need to experience time.
