The whole of our reality exists in a wave-particle duality.
What the wave-particle duality means at a quantum level is that our supposedly solid reality is not actually solid at all.
Everything exists in an oscillation or a hazy-wave; it is ill defined. This hazy-wave condition remains the same until a particle is observed, whereupon it changes from being somewhere in a hazy-wave state to being solid and existing in a definable place.
