ELI5: Explain Like I'm 5

Scale invariance

Scale invariance means that an object looks the same no matter how much it is zoomed in or out. To explain it another way, an object that is larger or smaller can still look or be the same as the original object. For example, if you have a picture of a square and you zoom in on it, the shape of the square will still look the same, no matter how much you zoom in.
