The Merriam-Webster dictionary defines reality as 'something that is neither derivative nor dependent but exists necessarily'. In nature, the position and momentum of a particle cannot both simultaneously be known with infinite precision (Heisenberg uncertainty principle). For something to be real, its existence must be confirmed by some sort of interaction/measurement/observation (direct or indirect).
If no interaction/measurement/observation can be made with a "thing", from your perspective that "thing" does not exist. Because "things" in the universe are separated (spatially and temporally) they each have a unique perspective (coined term: "perspective-state"). Because things have unique perspective-states, the "reality" (interactions) they see is also unique. It is my view that there can be no global definition of reality, each "perspective-state" necessicarily has its own reality (universe). Perspective-states are quantized (plank-scale and plank-time) and so reality, because it springs from the interactions (which are quantized) between things at other "perspective-states" makes reality a quantized property of each perspective-state.
