Here’s a preview of an article of interest at Scientific American (August 1):
Many physicists think that particles are not things at all but excitations in a quantum field, the modern successor of classical fields such as the magnetic field. But fields, too, are paradoxical.
If neither particles nor fields are fundamental, then what is? Some researchers think that the world, at root, does not consist of material things but of relations or of properties, such as mass, charge and spin.
But information is fundamentally relational, so is this saying that the basic substance of the universe is information? Or … or what?
