Figure 1. I create two images labeled A and B. In image A at point P, there is a point-wave source in a two-dimensional medium that has emitted wave fronts. These wave fronts are ring shapes expanding outward from the center. According to Huygens, these wave fronts are constructed out of an infinite number of point-wave sources [6]. The line drawn from points P to Q follows the contour of the waves and is smooth and continuous. Any line that follows the contour of the waves will be smooth and continuous because the waves in all directions mesh this way. In image B, I represent some of these wave sources with arrows. Notice that there is only one arrow associated with each distinct point-wave source on the outer wave front. This is not the case for the wave source at the center, which has arrows in all directions pointing away from it. This represents an important difference between the central wave source and wave sources on a wave front. Wave sources on the wave front only emit a wave in one direction, whereas a central point-wave source emits waves in all directions.

Freezing the wave motion, I could walk along the blue circle in image B and never experience any phase change. Hence, there are no waves waving in the direction tangent to the blue circle. Therefore, point-wave sources on the blue circle are only point sources for waves in one direction. However, at the central point-wave source, waves are waving outwardly in all directions. This is a fundamental difference between the two types of wave sources. Nonetheless, I could coalesce all of the point-wave sources on the blue circle, and these would sum up to equal the central point-wave source. Because of the aforementioned differences, I illustrate that the point-wave sources that are components of a wave front are bosons and that the central point-wave source is a fermion in the cosmic quantum medium.
