Photon

Photons were the particles that carried electromagnetism. These particles had no mass, and thus traveled at the speed of light (in fact, the speed of the photon was the definition for the speed of light, as photons were the particles that made up light). Photons had a spin of 1, making them part of the Grand Unified Forces, which also included Gluons, Debilons and Nullons.

Photons were responsible for creating electromagnetic charge in particles (although they themselves had no charge). Photons within an electromagnetic system would flow from the negative pole to the positive pole, creating the force between them. This kind of interaction was responsible for binding electrons to nuclei, creating atoms, and in turn was responsible for all chemical reactions between atoms. It was also responsible for creating planetary magnetic fields, which were often important in shielding life-bearing planets from stellar wind.

Light was made up of free photons (photons that were not part of an electromagnetic field). Like all other spin 1 force carriers, photons exhibited wavelength, which corresponded to energy. Short wavelength photons were gamma rays, whereas longer wavelength photons were visible light, and the longest of all were radio waves.
