Published in physic.philica.com Observation There are three orthogonal vectors associated with the propagation of a photon. These will be investigated utilizing a pyramidal coordinate system that doubles as a physical model. Draw a pyramid and label the xy base legs 1/Pe and 1/Pm (the inverses of the vacuum electric permittivity and the vacuum magnetic permeability). The xy base surface area now represents the electromagnetic susceptance properties of spacetime as well as C^2, light speed squared. Label the zaxis to be a perpendicular vector pointing in the direction of travel of a photon, times C. As the xy field boils up and down inside the volume of the pyramid, it acts just as the surface of the sun. Here are three related situations:
1. A hydrogen atom electron has just now dropped down one orbit, thereby “pinging” the xy “spacetime susceptance field”, thus causing a single photon to move up the zaxis. This photon is at all times at C, because the spacetime electromagnetic susceptance is an energy carrier that is always oscillating in all directions at C, with granularity of action = Planck’s constant, h. The upper area of the pyramid gets smaller, just as the volume of spacetime appears to diminish with distance.
2. Now equate the speed of light to be the speed of time. The pyramid demonstrates the properties of time.
3. Next, label the zaxis to represent potential energy. Place the mass of an object, or the electron energy bands of an atom, or the relative energy of a moving object, upon this zaxis, which now represents the potential energy of the spacetime field. As objects of our world are tested in this pyramid, what they have in common is this: the xy base represents the potential energy available in spacetime’s orthogonal susceptance structure.
