A photon is the smallest piece of light. This is one photon trapped, one particle, seen from the inside like before. You saw before how it hides space and makes gravity. The direction it goes makes charge.
Where the head meets the tail you can see how it hides the space around it, strongest up close, fading at the speed of light as it moves away. As it spins, it swooshes a bright ribbon through the grey, the swoosh always curls the same way it spins.
spins this way, minus charge
spins the other way, plus charge
