1 electron carries 1 negative charge

if we smash the electron into 1000000 equal pieces, each piece will carry 1/1000000 negative charge. Let's call it enertron.

since enertrons carry the same negative charge, they repel each other.

if we have a perfect bottle, which means no leakage, no react, like glass bottle to air.

we put 1000000 enertrons into the perfect bottle, since enertrons repel each other, they put a pressure on the bottle wall. let's measure and call that pressure 1 vote.

if we put 2000000 enertrons into the same bottle, the pressure on the wall should be 2 vote.

now if 1 enertron is moving or vibrating, the rest all enertrons will share the force according to their distance.

that is the mechanism of light/quantum.
