Essay Abstract
In the spirit of ancient atomism, the quantum of light was renamed the photon, the fundamental element of everything. Since the photon carries energy on its period of time, a flux of photons embodies a flow of time. The flows of quanta naturally select optimal paths, i.e., geodesics, to level off energy differences in the least time. While the flow equation can be written, it cannot be solved because the flows affect their driving forces, which in turn affect the flows, and so on. Since the forces, i.e., causes, and motions, i.e., consequences, cannot be separated, the future remains unpredictable. Similarly, when a computation affects its own course, it remains uncomputable. And a problem remains undecidable when time does not advance, as the flows of quanta, instead of finishing up, get caught up in circulating.
