The Planck scale is a theoretical framework in physics that seeks to understand the smallest possible scales of length, time, energy, and matter in the universe. It is named after the physicist Max Planck, who first proposed the concept. At the Planck scale, gravity is believed to become as strong as the other fundamental forces, leading to the need for a unified theory of quantum gravity. Research in the Planck scale seeks to reconcile the principles of quantum mechanics and general relativity, as well as explore the fundamental building blocks of nature at these extreme scales. This area of research has the potential to revolutionize our understanding of the fundamental laws of physics and the nature of reality itself.
