This is one of my favorites discussion of the Planck scale, I'd strongly recommend it. https://www.physicsforums.com/insights/hand-wavy-discussion-planck-length

  Indeed, very cool. Plus, John Baez commented: > Another way to think about the Planck length is that if you try to measure the position of an object to within in accuracy of the Planck length, it takes approximately enough energy to create a black hole whose Schwarzschild radius is… the Planck length! That sounds familiar, here.
