APPLICATIONS OF THE GENERALIZED UNCERTAINTY PRINCIPLE IN MODERN PHYSICS

Abstract

The Generalized Uncertainty Principle (GUP) introduces a modification to the Heisenberg Uncertainty Principle by incorporating a minimal length scale, expected to emerge from quantum gravity theories. This modification suggests that at scales close to the Planck length, the conventional description of spacetime may break down, necessitating new physics. Despite its theoretical appeal, experimental evidence for the GUP has yet to be established. This article surveys the current experimental efforts and future proposals aimed at testing the GUP. This article reviews the diverse applications of GUP, including black hole thermodynamics, quantum cosmology, and high-energy physics. We discuss theoretical implications, potential observational evidences and experimental constraints highlighting the GUP’s role in the advancement of our understanding of fundamental physics.
