If a photon experiences no time, could all photons we observe from our reference frame really just be the same photon in every possible position in the universe?

I'm a photon/relativity noob, so please excuse my ignorance. I often wonder about the fact that an object that moves at c experiences no time. Does this not imply that a) from our reference frame the same photon must be at every conceivable point in the universe simultaneously, and that b) there is just one single photon? Could this explain the strange results of the double slit experiment? Just a thought!

Nope. It's pretty trivial to show that a photon propagating along a geodesic trajectory cannot deviate from that trajectory. If it did, then there would exist some inertial reference frame in which the photon, during deviation, was not propagating at *c,* which is prohibited by the principle of covariance.
