    Calling Planck units “pixels” is extremely reductive. This is just naively applying video game concepts to physics with a poor understanding of both.

      I took an entire graduate course in QM and a quantized Universe does, in fact, seem pixelated. That’s exactly how I explain it to people. There’s simply a finite level to how closely you can zoom in.

        isn’t the most recent explanation on planck’s length saying that we simply can’t observe further down, but it is hypothesised that smaller lengths actually exist?

          Just searched a bit, looking into how the length came to be and found this from wikipedia. https://simple.m.wikipedia.org/wiki/Planck_length “The Planck length does not have any precise physical significance, and it is a common misconception that it is the inherent pixel size of the universe.” What I found elsewhere was that it’s the only length one can get out of the universal constans of G, c and h. So as far as I know with my limited know how is that the planck length is useful or more convenient than other lengths in quantum physics.
