You’ve just blown my mind.

  Another mind-blowing perspective is from that of a single photon; since time slows when approaching c, from its perspective it's eternal, and, since distance shrinks when approaching c, from its perspective it's also omnipresent.

    Well, it's not exactly eternal, it's that time is not passing for that photon. It's also (as far as I can tell) only correct to say that distances shrink as speed increases when you're talking about massive objects. A photon would not experience space contraction in any meaningful way.

    By eternal you mean the photon will "experience" being a phonon when it's absorbed by matter?
