• So when a gravitophoton pair is created the theory predicts that each particle will react with matter differently.
• The attractive gravitophotons have a large cross section of absorption and will interact with protons and neutrons, thus being able to impart a force on material objects. 
• The repulsive gravitophotons only interact with electrons and gravitons, since their cross section absorption is a lot smaller the force imparted is negligible compared to the attractive particles.
• The total force imparted to nearby objects is called the heim-lorentz force and calculated by the simplified formula: 
• This is the basis for a propulsion device.
