The speed of light is traditionally considered a fundamental constant. A core postulate of modern physics states that the speed of light in a vacuum is the same for all observers, regardless of their motion or the motion of the light source. This principle is embedded in both Special Relativity (SR) and General Relativity (GR), and its validity has never been questioned. However, several key aspects allow us to reconsider this postulate. In this article, we will examine the foundations upon which...

Modern physics operates with a number of fundamental constants, among which Planck's constant h occupies a special place. However, if we consider the process of scaling physical quantities through resonant waves, we can assume that Planck's constant is not an independent quantity, but is derived from the speed of light and geometrical characteristics of wave processes. Many physical phenomena are based on resonance. If we consider standing waves at different scales, we can identify their common patterns...
