Planck scale

The Planck scale is a set of physical measurements that represent the smallest possible size and time intervals in the universe, based on fundamental constants like the speed of light and gravitational force. At this scale, around \(10^{-35}\) meters for length and \(10^{-44}\) seconds for time, the usual laws of physics break down, and quantum effects of gravity become significant. Essentially, it’s where our understanding of physics, as described by general relativity and quantum mechanics, starts to merge, hinting at the limits of our current scientific theories regarding the nature of space and time.
