The Concept of Plank Length and Minimum Distance

They delve into the fundamental nature of reality, the imposition of coordinate systems, and the possibility of space being pixelated. They explain that the Planck length is a candidate for the minimum distance in the universe, but it is oversold and only a rough estimate. They emphasize that it is a hand-wavy argument and a terrible estimate, but it is still used because there is currently no better alternative.
