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.
