Time is a total figment. An illusion. If we were photons we would cross the entire universe instantly. Go ahead, resolve the illusion to a finer degree of instantaneous.
How ‘big’ is a photon? And you just made my earlier point (made a few years ago on one of these insane threads) that photons are a little bit of space, a little bit of time, and energy ... they cross the universe always in the present of when they were formed, so the background temporal reality they do not interact with until they ‘arrive’ at something with an ‘accumulation’ of time.
