Hence, what remains, are the nearby paths in spacetime only-the ‘light-like’ intervals only: a small core of space which our photon effectively uses as it travels through empty space. And when it encounters an obstacle, like a sheet of glass, it may or may not interact with the other elementary particle–the electron. Hence, our photon may actually travel slower or faster than the speed of light c! There is one lucky break, however, that makes all come out alright: the arrows associated with the odd paths and strange timings cancel each other out. Now, in quantum theory, anything is possible and, hence, not only do we allow for crooked paths, but we also allow for the difference in time to differ from l/ c. the ‘distance in time’ as measured by that stopwatch hand). the ‘distance’ in space measured along the path, be it straight or crooked), and (2) the difference in time between the departure (at point A) and the arrival (at point B) of our photon (i.e. We just associate each and every possible path (in spacetime) between A and B with an amplitude: an ‘ arrow‘ whose length and direction depends on (1) the length of the path l (i.e. All points in space are connected by an infinite number of paths – straight or crooked, whatever – of which we measure the length. And then we have ‘photons’ that move from A to B, but so we don’t know what is actually moving in space here. Let’s recall the story once again. Space is an infinite number of three-dimensional points (x, y, z), and time is a stopwatch hand going round and round-a cyclical thing. In the previous posts, I showed how the ‘real-world’ properties of photons and electrons emerge out of very simple mathematical notions and shapes. I might review them one day, but I currently don’t have the time or energy for it. I keep blog posts like these mainly because I want to keep track of where I came from. In any case, we recommend you read our recent papers. In addition, some of the material was removed by a dark force (that also created problems with the layout, I see now). Pre-script (dated 26 June 2020): This post has become less relevant (even irrelevant, perhaps) because my views on all things quantum-mechanical have evolved significantly as a result of my progression towards a more complete realist (classical) interpretation of quantum physics.
