Space is full of gravitons. Gravitons interact with each other and convert to color-charges. Interaction between gravitons depends on their density in a given volume. Energy production is given by:

However, positive color-charges repel each other, and the same action applies to the negative color-charges.

Therefore, when the intensity of color-charges grows, about each field (negative and positive fields), a magnetic field forms. This magnetic field maintains the electric field. This mechanism is explainable by the Larmor radius (gyroradius or cyclotron radius) given by:

This defines the radius of circular motion of a charged particle in the presence of a uniform magnetic field. When color-charges change in the structure of a photon, then magnetic-color changes too. Therefore the electric fields do not decay in the structure of a photon.

In general, a photon has been formed of two parts:
