> An error in this type of thinking is that it assumes that the observer isn’t also made of light. Well, yes. Light has an entirely different model of the universe than we have. To a photon, clocks don't tick at all, so a photon says "What is this 'time' you speak of?" And since photons are "always" exactly "where" they intend to be without time passing, they also say "What is this 'space' you speak of?" Our view of the universe must seem very weird to a photon.
