Four-Dimensional Field of Light and Shadow: A New State of Light

The concept of a light source capable of directly exhibiting the spatial characteristics of a photon within observed reality—without reliance on instrumentation—has been previously considered and subsequently dismissed due to the complexity of its implementation. However, this discovery demonstrates that a specific type of light source allows such validation. When this nearly spherical light source—composed of vertical bands—diffuses its brightness throughout a room, bright and dark vertical fringes are visible on a screen inside a box equipped with a vertical slit. Notably, when the source is tilted, these fringes remain vertical, indicating the presence of a field that interacts with space. Introducing a three-dimensional coordinate system onto the fringe screen reveals inconsistencies as the inclination of the source changes. These inconsistencies stem from the overlapping trajectories of nearby fringes, which occupy mutually incompatible spatial positions. To resolve this, the geometry of the fringe screen must be constrained such that only one dimension is defined, with two distinct color states. Through the application of geometry links between physical parameters, these two color states necessitate a method for constructing a valid four-dimensional Euclidean coordinate system. This new system represents an advancement over the conventional four-dimensional R-vector space by explicitly defining the fourth dimension. Within the four-dimensional reality of the box, it becomes possible to derive the full geometric characteristics of an observable photon, as well as a discontinuity in the direct propagation of light and shadow through space.
