The inexhaustible source of insights revealed by every photon

We present several quantum mechanical experiments involving photons that strain the notions of space, time and causality. One for these experiments gives rise to the "quantum liar paradox," where Nature seems to contradict herself within a single experiment. In the last section we propose an outline for a theory that aspires to integrate GR and QM. In this outline, i) "Becoming," the creation of every instant anew from nothingness, is real. ii) Force-carrying particles, such as photons, do not merely mediate the interaction by propagating in some pre-existing, empty spacetime; rather, they are the very progenitors of the spacetime segment within which the interaction takes place.
