Spinity and impelity (Momentity) in universe Frame dragging force is a newly identified force. Here, I rename this force “spinity ” or “spinnism ” because this force is generated by spinning mass. I propose here that “rest mass produces gravity, spinning mass produces spinity; rest charge produces Coulomb electric force, spinning and moving charge produces magnetism”. Frame dragging effect was derived by Dr. Lense and Thirring to describe the procession of an orbiting object using general relativity1. Nobel prize winner Dr. LD Landau also derived orbiting object’s lagrangian around central spinning mass using general relativity2. However, these professors didn’t point out that frame dragging is actually a new basic force which has a close relation with gravity. When an object has mass, it will have gravity to attract its parts to the center. In order to overcome this continuously centripetal force, the object needs to spin to produce centrifugal force to balance gravity. When the object spins, spinity occurs. I propose to call this new force “spinity ” because it is a combination of “spin ” meaning origin of this force and “ity ” meaning basic force. Frame dragging means a spinning mass can drag nearby space-time to rotate around the mass, so it is actually a force which can cause peripheral smaller object to orbit around the central mass according to the basic concept of general relativity. Below is the summary of Professor Landau’s derivation from general relativity: (J:central mass angular momentum,r’=unit vector, vector g direction=Jxr’, vector g is spinity field
