"The thing that produces quanta is the loss of energy. Electron shell-size decay is what produces quanta. What we call "light" is electromagnetic energy that has been shed. Light is also waves passing through space. The waves aren't things unto themselves, but are ripples in space. This means that light and space are one and the same thing. And since light comes from the collapse of electron shells, the electron itself is space in another form. Collapsing electron shells are like bubbles of space bursting."
