The study displays that the photon consists of a positive charge and a negative charge. A gravitational singularity in the universe generates synchronized, extremely low frequency gravitational waves consisting of extremely low frequency photons. This photon was exposed to a magnetic field resulting in that the photon was split into a separate positive charge and a separate negative charge. These charges were exposed to electric fields, revealing their nature. It is proposed that the photon’s positive charge rotates clockwise and the negative charge rotates counter clockwise perpendicular to the photons radial direction forming a double helix. The photon’s radial speed is equal to the speed of light. The charge’s rotational speed is equal to the photon frequency ν. The study describes how the photon’s charges were measured. The study describes a method to measure how e.g. an incandescent light bulb and a radio transmitter antenna generate photons, revealing the true nature of photons. The study describes the relationship between photon, gravity and the atom’s elementary particles.
