If someone invited you to live in a world where every physical thing—granite, stars, trees, the bones in your body—lost their thingness, would you accept? The fact that things exist is very reassuring, so reassuring that we can hardly do without it. Unfortunately, this reassurance is false. We live in a world where things aren’t really things, whether we choose to or not.
Matter, the physical side of matter and energy, is one half of a duo act. We are told matter is what the universe is made of, and energy is what puts matter in motion. The dance between them constitutes the reality we inhabit, a fact so obvious that modern science relies upon it as the unquestioned basis for doing science, not to mention for leading our everyday lives.
If matter and energy are not what they seem, science could be rocked to its core—but great care is taken for this not to happen. Strangely, a nursery rhyme tells the tale. Like Humpty-Dumpty in the English nursery rhyme, physical matter—solid, tangible inert matter composed of atoms and molecules- took a great fall over a hundred year ago, when quantum mechanics demolished every one of those qualities. It is entirely inaccurate to envision the universe being built up from bits of solid matter—or bits of anything.
The ancient Greek notion that reality can be reduced to a minuscule speck of matter (the atom) was a delusion of logic, and therefore a mental construct 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.
The dissolution of physical matter isn’t controversial—quantum mechanics is the bedrock of modern physics–but it turned out to be intolerable for working scientists. They rely upon the reassuring nature of thingness just as much as ordinary people. Theoretically, doing away with thingness should have been the end of the story. As every child knows, all the king’s horses and all the king’s men couldn’t put Humpty-Dumpty together again. Physics, however, managed to do something more mysterious. It ignored that matter fell and broke in the first place.
