What is the Planck Length, why’s it significant, and how could we even detect something that small?

Been a while since I’ve studied the Planck length, but will try to give it a go.
Instead of thinking of it as the small possible measurement of length, I’ve always thought of it as the resolution or “pixel” of the universe. For example you can stand in place and move forward one foot. You can say you made a journey of 1 foot in length. That means you started at point zero and ended one foot away. You moved through all the infinite points in between. You can also make a journey that is 1 inch long or 1 cm long….all the way down.
When you get to the Planck length you no longer can make such a journey. You start at point zero and move 1 Planck length away. You did not cross all the points in between. You teleported 1 Planck length away from your starting point.
Welcome to the quantum scale – where all the “rules” are wrong…and so much more exciting.
