The Planck Distance

Introduction The Planck distance is traditionally defined as the smallest physically meaningful scale, below which classical notions of space and geometry cease to be valid. In directional geometry, this distance plays a fundamental role: it represents the minimal granularity of internal directions, meaning the smallest directional unit a domain can sustain. In this framework, the Planck distance is not merely a theoretical limit arising from quantum physics; it becomes a directional measure, directly linked to a domain’s ability to generate internal subdivisions. The central question is therefore: Is the Planck distance truly the minimal granularity of the universe? Directional geometry proposes a unique way to verify this hypothesis: analyzing the directional saturation of a black hole.
