Photons

Photons are built up somewhat like atoms of smaller particles.

The yin is responsible for the positive charge.

The yang is responsible for the negative charge.

The yin and the yang combine to form the primary yu photon.

The primary yu photon's equivalent wavelength is in the microwave region. Is it the "primordial" background radiation?

Photons with equivalent wavelengths longer than microwaves are composed of yin and yang.

Photons with equivalent wavelengths shorter than microwaves are composed of primary yu photons.

Photons have inertia therefore they have mass. Energy is mass in relative motion.

Photons with shorter equivalent wavelengths have greater mass and composed of more yu photons than photons with longer equivalent wavelengths.
