Sorry, I was oversimplifying/you’re right, time doesn’t slow down the smaller you get; I was thinking of how the smallest interval of time at the Planck scale can’t be defined with physics as we know it right now.

But iirc the closer you are to a higher concentration of gravity the more time slows down? I read it in a book Reality is Not What it Seems so I’m just lazily parroting things I have a casual interest in.

We can define time at any arbitrary scale, Planck time is more like a limit to what we can measure.

Time doesn't slow down on a massive object in its own reference frame. Think of the "one hour here is seven years on Earth" meme from Interstellar. To them, time is moving normally, but relative to Earth, it's moving really slowly.

Time only passes differently relative to other reference frames (their planet and Earth, for example). Thus the theory of relativity!
