…truct only. In reality the elementary particles that comprise the atom have a mysterious existence. They have no measurable weight, position, or any other characteristic until they are observed. Before that, they exist as waves that extend infinitely in all directions. These waves have no properties you can assign to any solid object. They arise as ripples in the quantum field, and the entire structure of the universe is mathematically described as interference patterns among these ripples, like the pattern formed on the surface of a pond if you throw two rocks in at the same time.
