The analysis of Planck units reveals that they represent not merely mathematical constructs but fundamental limits of nature: distances, times, and energies smaller than these values do not exist. This eliminates singularities and necessitates a revision of the foundations of general relativity and quantum field theory. The law of integer parametrization is introduced: any interval contains an integer number of natural units, while connected field systems are characterized by a common quantum number k. It is shown that the fundamental constants (G, ħ, c, α) are expressed through ratios of these units. The fine-structure constant α = 1/137 is identified as the ratio of quantum numbers of gravity and electrostatics, revealing a deep entanglement of these interactions. A formalism is proposed in which electrostatics is treated as a modulation of the gravitational field; a dimensionless modulation function Ψmod, analogous to spherical harmonics, is introduced. The electron mass, estimated as the energy of the phase defect of modulation on the fundamental mode n = 137, yields the correct order of magnitude. It is concluded that a five-dimensional wave description of the world as a continuous energy density field is required.
