The graviton makes gravity difficult to explain. It must move in a wave form, since evidence of gravitational waves have been discovered.http://www.cnn.com/2016/02/11/us/gravitational-waves-feat/
Thus the graviton is moving in a wave form. The graviton is a particle and the gravitons on the Earth repel the gravitons from the Sun. This creates a balance and allows the Earth to maintain its orbit and not randomly move closer to the sun or further away from the sun.
The most important point about the graviton concerns its wave form or movement! As the graviton moves from its source of mass, then it acts like a push on other matter in the way. As the graviton moves from its farthest point and begins to return to its original mass, then it acts like a pull. This would be the pull of gravity that Isaac Newton described.
Gravitons can group together, just like photons and form gravitational waves. The larger the mass of the system results in the formation of a higher frequency of gravitons with smaller gravitational waves similar to blue or violet light that can be produced during electron transition of energy levels during the burning of a metal or during fusion in the sun. Most of the hydrogen in the sun resists fusion, since the majority of hydrogen in the sun is hydrogen with only one proton and zero neutron. Hydrogen with a mass of two will fuse and form Helium. Hydrogen with a mass of three will fuse with hydrogen one. Hydrogen two and Hydrogen three are not abundant, and this is the reason the sun consistently undergoes fusion for a long period of time. Moreover, the fusion process releases a lot of energy from just a small number of atoms being fused. Thus the Sun's gravitational push and pull extends farther than the Earth.
Electron transition between energy levels creates visible light, thus photons bond together forming different wavelengths. Photon bonding is a new study of science that we know very little about due to the small mass of the photon. Gravitons most likely bond together as well. The bonding of the photons can be broken physically with a prism, so the strength of its bonding will be weaker than van der Waals forces. The size of the atom determines the color of the light emitted when electrons transition during a flame test. This indicates that the gravity of a hotter or warmer object should be stronger than the gravity of a cold or cooler object. Temperature is a measure of movement and for gravitons to group together in a wave form of high frequency would require greater movement. The strenght of the gravition bonding is unknown, similar to the strength of photon bonding, since no experiment has been done to examine it. The Sun over long periods of time eventually degrades, thus the strength of the gravitational wave would decrease due to the cooling effect. Graviton bonding is most likely stronger than photon bonding, because of it's higher frequency and velocity.Can gravitons affect the movement of light?
