but he’s not saying that the Planck’s length is the pixel size of our universe.
And neither was I. But what he IS saying is that there’s a limit to how closely you can measure length in any dimension. Thinking of it like pixels is a useful metaphor because that’s an indivisible unit, and it’s what’s behind Planck’s constant. But a Planck length is really only relative to quantum gravity, not QM generally.
