This paper explores the role of quantum black holes – rotating charged microstructures, in deciphering the quantization properties of elementary particles. It introduces the limits of physics, resulting from applying the principles of "Uniformity of Physical Laws in the Universe" and "Energy Conservation," ensuring there is no infinite Energy anywhere in space-time. Following these principles introduces the known speed of light limit and a new limit: the highest possible matter density in the Universe limit. Quantum black holes release their Energy, altering the curvature of nearby space-time. Their inability to retain additional Energy positions them as the structures for elementary particles. If considered elementary particles, the radii of quarks and leptons as quantum black holes fall significantly short of observations' measurements. Therefore, this paper suggests that quarks and leptons are complex particles made up of much tinier elementary particles, and it further elaborates on these fundamental components.
