Why does physics break down at the Planck scale?
Briefly

The article discusses the enduring nature of physical laws throughout the universe, encompassing known Standard Model particles and theoretical extensions like grand unification. It highlights the inherent limitations imposed by the Planck scale, where traditional physical predictions become uncertain due to the incompatibility of quantum mechanics and general relativity. Notably, while black holes can form from concentrated masses or energies, their lifespan is curtailed by Hawking radiation acting within Planck time. The future goal of quantizing gravity aims to explore the trans-Planckian regime, unveiling deeper cosmic mysteries.
The laws of physics are constant across time and space, forming the backbone of our understanding of the Universe's fundamental structure.
At the Planck scale, traditional physics gives way to uncertainties, indicating a fundamental disconnect between quantum mechanics and general relativity.
Particles exhibit wave-like behavior attributed to their inherent wavelengths, complicating predictions at high energies and short distances.
While black holes may form in extreme conditions, they decay rapidly via Hawking radiation within a time frame defined by the Planck unit.
