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.
We are going to be sorry we ever listened to Einstein. From 1905 to now we have been thinking there are photons and that time is another spatial dimension. There are no photons, Einstein invented them, and while he didn’t make time out to be another spatial dimension he didn’t object when Minkowski did that very thing. Einstein misread Kant, as do most of us.
