Time doesn’t pass for a light particle, I don’t think.  Just like Vonnegut’s Tralfamadorians, light “experiences” all its moments, everywhere it will ever go, at once.

I think this “inverted” way of thinking about time and space is the right one.  We aren’t moving around in time — we’re moving with respect to fixed light cones in both space and time.

This way of thinking makes unparadoxical the constancy of light’s speed in all reference frames. Rigid space-marking rods are not the guideposts by which the universe is measured — timeless, spatially extended photons are.

UPDATE: Nice video rendering of photons by NASA.
