I’m not really into physics and what not, I just know the bare minimum. I’m a law student, so please believe I’m like 5 when it comes to this discipline of education.
Why is the Planck Length the “smallest thing in the world?” Or at least I hope I asked it right.
I’ve read that you cannot go smaller than this length, otherwise blackholes will occur and the world doesn’t make sense anymore.
Could you explain the main steps to understanding “length” and it’s relationship to energy before diving into the planks length? This concept is super interesting and I really want to understand it. From what I have read, understanding this concept is broken down like this:
(1) What is a wavelength actually?
(2) How are wavelengths and energy related?
(3) Why is the Plancks Length the smallest thing in the universe?
(4) What happens when something is smaller than a Planck Length?
Thanks!

Paul Shillito (Curious Droid) just did an excellent video on scales from the very big (light-year) to the very small (Planck length): [The Scale of Everything](https://www.youtube.com/watch?v=ST7EP7xnriM). Worth a look!
He explains the Planck length as such:
>Think of a dot that has the same diameter as a human hair, about 0.1mm. This is about the smallest thing we can see unaided. If that 0.1mm dot were magnified to the size of the observable universe, all 93 billion light-years of it, then the Planck length would be the size of a 0.1mm dot in comparison.
