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.
