    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. Space, time, and energy are all quantized, and maybe even gravity though we haven’t figured that one out yet.

      A finite level to how close you can zoom in is very different from pixels. Pixels (or voxels in this case) are indivisible elements of a larger whole that exist along an evenly spaced grid. The universe doesn’t have a Cartesian coordinate system measured in Planck lengths

        Pixels (or voxels in this case) are indivisible elements of a larger whole that exist along an evenly spaced grid.

        That’s exactly what a Planck unit of spacetime is. And yes, the Universe–like a screen–is divided into an evenly-spaced grid any time you choose a coordinate system.
