I still find fascinating that if you want to "zoom in" a lot, eventually you'll need so small wavelenght (and so much energy) that you create a tiny black hole in the process. "Coincidentally" it's at the scale of plank lenght.
Also 1000t black hole has smaller (schwarzchild) radius than atomic nucleus, which kinda makes you scratch your head (even more) about the reality of particles. Are the black holes really "particle like", but at the same time they can grow into a macroscopic sizes?
