Here's my thinking: The faster you go relative to the universe, the more the universe appears to contract. However, c remains constant as measured by distance/time. Now, what about to a photon? To a photon, the entire universe would appear as a single point, correct? To this same photon, c would remain constant as observed by the photon. But how can the photon know this? It's entire distance is infinitely small, and therefore it can't perform the distance/time measurement. Is my logic wrong?
