At Planck scales, things aren't so much "granular" as they are "fuzzy". Positions and such can be smeared out in a wave, rather than being discrete. Measurements, however, are often discrete, and select a single [eigen]value from the smear. Between the wave / and the measurement / falls the Shadow,
